Maitreya's Twenty-Six Questions on Calm-Abiding and Insight

Master Cháng Bǎi opens this fascicle by placing it within the Chapter on Excellent Qualities' full sevenfold citation of the Saṃdhinirmocana Sūtra, which he divides into four topics of "object" and three of "practice and result." The first four — the characteristic of the ultimate truth, the characteristics of mind, intellect, and consciousness, the characteristic of all dharmas, and the characteristic of dharmas' lacking any nature of their own — occupied the previous two fascicles in full, laying out what a bodhisattva must come to know. This fascicle opens the fifth topic, the Chapter Distinguishing Yoga, which turns from what is known to how it is practiced: through calm-abiding and insight, the two wings of all Buddhist meditation. He explains "yoga" here in its full technical range, glossing four (and, by one later commentator's count, five) senses the term carries across the treatise and its commentaries — yoga of the object, meaning any object of contemplation approached without the distorting view of permanence, self, or purity and in accordance with the Buddha's own teaching; yoga of practice, meaning any cultivation, from the thirty-seven factors of enlightenment to the paired operation of calm-abiding and insight itself, that accords with reality, follows the teaching, and moves toward its proper fruit; yoga of result, meaning every fruit of the path, from a śrāvaka's four fruits to a bodhisattva's ten grounds, that likewise accords, follows, and fulfills its cause; and yoga of the sacred teaching itself, since the teaching that describes all of this is itself in accord with reality. He then turns to Maitreya, the questioner, explaining his name through three traditional accounts — that he took his mother's clan name, Maitrī, meaning loving-kindness; that loving-kindness samādhi was the very first meditative attainment he achieved, cultivating a heart of exceptional gentleness toward all beings from his earliest stages of practice; and that he vowed, on hearing a buddha named Maitreya teach him this same samādhi in a former life, to bear that name himself when he in turn attained buddhahood — and glosses "rely" as leaning on a cause or condition the way a drum's sound depends on both the drum and the hand that strikes it, and "abide" as the place or object one continues to dwell in and draw sustenance from once a practice has arisen, so that it may keep growing rather than degrade. He sketches calm-abiding (śamatha) as guarding the mind on a single object, free of scattering and agitation, ripening through nine progressive stages of mental abiding into a settled, luminous stillness sustained by the mental factor of concentration; and insight (vipaśyanā) as the searching, discerning examination of phenomena that this same stillness makes possible, sustained by the mental factor of wisdom, without which the subtle, deeply rooted afflictions could never actually be uprooted. Finally, he unpacks the seven marks of Mahāyāna "greatness" from an earlier fascicle that distinguish its calm-abiding and insight from the śrāvaka and pratyekabuddha vehicles' own: the greatness of its teachings, spanning countless vast and inconceivable scriptures; the greatness of its resolve, aspiring to unsurpassed awakening for the sake of all beings rather than to personal liberation alone; the greatness of its resolute faith in the Mahāyāna scriptures themselves; the greatness of its heightened aspiration, found only from the first ground onward, that never wavers back toward a lesser vehicle regardless of hardship; the greatness of the provisions of merit and wisdom it must perfect together; the greatness of the time it takes, spanning three incalculable eons; and the greatness of its final realization, unsurpassed awakening and great nirvāṇa themselves. It is within this vastly larger scope — object, motivation, scripture, resolve, provisions, duration, and result all alike expanded — that Maitreya now asks the question that will occupy this entire chapter: what must a bodhisattva rely on and abide in to cultivate calm-abiding and insight within so great a vehicle? The Buddha's answer names two things at once: the provisional teachings of the Dharma as what is relied upon, since no genuine practice can depart from the Buddha's own scriptural guidance, and an unrelinquished vow for unsurpassed awakening as what is abided in, since it is exactly this vow, held without wavering, that keeps a bodhisattva's cultivation of calm-abiding and insight from ever collapsing back into a lesser vehicle's aim.

Master Cháng Bǎi treats this exchange as the doctrinal core the entire Chapter Distinguishing Yoga builds on, and situates it within an earlier fascicle's larger map of four kinds of meditative objects: pervasive objects, which subsume every form of yogic practice and are exactly the four named here; objects for purifying conduct, five specific antidotes such as contemplating a corpse's impurity or loving-kindness for a hostile mind; objects of skill, five ways of analyzing experience by aggregates, elements, sense-fields, dependent origination, and the possible and impossible; and objects for purifying affliction, the objects of both mundane meditative absorption and the supramundane path itself. This chapter, he notes, concerns only the first, pervasive kind, because every other object a practitioner might take up still passes through these same four stages on the way to realization. He then works through what each one actually names. The image accompanied by discernment is insight's own object: a meditator who has properly learned some teaching — through direct study, a teacher's instruction, reading, or reflection — brings it to mind in meditative absorption, generating a mental image that counts as belonging to the same class as the original object contemplated; discerning wisdom then works on this image through four operations of increasing depth — judicious selection, its most thorough form, general investigation, and general, thorough examination — corresponding to grasping first the exhaustive particulars of a thing and then its true, underlying nature. The image without discernment is calm-abiding's own object: the very same counterpart image, now simply rested upon single-pointedly rather than analyzed, the mind drawn inward and settled through progressive stages until absorption is attained. The limit of things belongs to both together, since it names the twofold scope any object can be known under — its exhaustive particulars, meaning nothing remains of a thing once its constituent classes are accounted for, as there is no form outside the five aggregates and no aggregate outside its elements and sense-fields; and its suchness, meaning the reality established through four modes of reasoning — from relative dependence, from function, from what can be proven, and from the plain nature of things — corresponding, respectively, to conventional and ultimate truth. And the accomplishment of what is to be done also belongs to both together, since it names calm-abiding and insight's very fruit: joined and matured through repeated cultivation, they yield, in a practitioner who has passed beyond the image altogether, non-conceptual direct gnosis of the object itself — the same fruit the treatise elsewhere calls transformation of basis, unfolding by degrees from the provisional weakening of afflictive tendencies at the earliest stages of practice all the way to its full and final consummation at buddhahood. Master Cháng Bǎi closes by citing the Tang-dynasty master Chengguan's reading of these four through the lens of principle and phenomena interfused without obstruction: the image without discernment corresponds to principle, and the image with discernment to phenomena, practiced separately before the two are joined; the latter two objects then belong to non-conceptual wisdom itself, in which calm-abiding illuminates every phenomenon at once even as insight stills every principle at once — the paradox, as he puts it, of a wisdom that is stillness within seeing and seeing within stillness, indivisibly one.

Master Cháng Bǎi reads this as Maitreya's second question, now asking not what the objects of meditation are but how a bodhisattva actually works with them to seek calm-abiding and become skilled in insight. The Buddha's answer opens by naming the twelve traditional forms scripture itself takes, so that a bodhisattva knows what kind of teaching to bring into meditation to begin with: the discourses, plain prose teachings; verses restating in poetry what a discourse has already said in prose; explanations spoken in reply to a question, including a buddha's prophecy of a disciple's future awakening; verses standing entirely on their own, without any prose passage behind them; discourses the Buddha spoke unprompted, moved by joy or sorrow rather than any request, of which the Amitābha Sūtra is the most celebrated example; accounts naming the specific occasion — and often the specific person whose request, or whose offense, prompted a teaching or a monastic rule; parables, exemplified by the Sūtra of a Hundred Parables' hundred illustrative stories, such as the king who credited a physician's medicine for his daughter's twelve years of natural growth; accounts of disciples' own past lives, explaining a present trait through some past-life event; accounts of the Buddha's own past lives practicing the bodhisattva path, as the nine-colored deer or the elephant king; teachings of vast scope, the Mahāyāna sūtras proper, called vast because what they describe — every power, every fearlessness, every unobstructed knowledge belonging to a buddha — is itself vast beyond ordinary reckoning; accounts of what is rare and wondrous, celebrating some quality shared by no other teacher or disciple in the world; and treatises of systematic exposition, which either directly comment on a single sūtra, as the Treatise on the Great Perfection of Wisdom comments on the Larger Prajñāpāramitā Sūtra, or gather and organize a scripture's themes through questions and answers, as this very treatise does. Together, he notes, these twelve reduce to three: the discourses themselves, the monastic code folded into the "occasion" category, and the treatises of the twelfth category alone — sūtra, vinaya, and abhidharma. Only then does he unpack the fivefold practice by which a bodhisattva actually takes hold of this material, glossed by the Reflections on the Categorized Verses with real economy: listening free of any distortion is listening well; retaining free of any distortion is receiving well; reciting aloud until the words flow without hindrance is becoming well versed; applying the mind exactly as reason directs is reflecting well; and coming to know exactly as reality is, is penetrating well in view. He adds that "listening well" here means listening specifically to inner knowledge — the Buddhist canon itself, one of five traditional fields of study alongside logic, linguistics, medicine, and the practical arts — free of four faults: the arrogance of assuming one already knows it, the timidity of assuming it too deep to grasp, the distraction of a wandering mind, and the defilement of letting greed, hatred, or delusion run alongside the listening itself. Each stage, Master Cháng Bǎi stresses, is the necessary condition for the one after it — listening enables receiving, receiving enables fluency, fluency enables reflection, reflection enables penetrating insight — forming one continuous preparation before a bodhisattva ever sits down, alone in a quiet place, to apply the mind in earnest to what has been so carefully readied.

Master Cháng Bǎi maps this passage's "sustained inward reflection" onto the first four of the nine progressive stages of mental abiding an earlier fascicle lays out in full — internal abiding, continuous abiding, patched-up abiding, and close abiding — with the remaining five stages, taming, pacifying, utter pacification, single-pointed focus, and full absorption, still to come. Internal abiding is simply the mind drawn back from every outward object and bound instead to a single internal one, such as the breath or a corpse's impurity, so that it stops running out toward the senses altogether. Continuous abiding follows because that bound mind is still coarse and turbulent: the power of mindfulness is now used to sustain the continuity of attention, wearing down dullness and agitation until the mind grows subtler and less erratic than before. Patched-up abiding is needed because mindfulness still occasionally lapses, letting the mind wander outward again, so the same methods of sustaining and clarifying attention are applied once more to draw it back and resettle it. And close abiding follows once this repeated remembering has done its work, keeping the mind close enough to its object that it is no longer drawn away by sounds, sights, smells, tastes, or textures arising outside. The first two stages, he notes, are established chiefly by the power of prior hearing and reflection, while the latter two are established by the power of mindfulness itself. He is careful to stress what actually marks calm-abiding's true completion: not merely sustained concentration, however refined, but the arising of bodily and mental pliancy — a genuine ease and workability of body and mind that the Establishment of Consciousness-Only Treatise defines as what removes coarseness, renders body and mind fit for use, counteracts torpor, and functions precisely as a transformation of basis, subduing whatever had obstructed concentration so that what it rests upon becomes truly at ease. Until this pliancy actually arises, Master Cháng Bǎi notes, no amount of sustained concentration yet counts as calm-abiding accomplished — only once it does can the practitioner move on to what full skill in insight requires.

Master Cháng Bǎi stresses that calm-abiding's pliancy is not the end of practice but insight's own precondition — only once that ease of body and mind is established does the same meditative image become the ground for genuine discernment. He walks through the three steps this passage names using the classic contemplation of a corpse's impurity as illustration. Observing comes first: the four operations of judicious selection, its most thorough form, general investigation, and thorough examination are turned on the mental image itself — here, the bluish, discolored appearance of a corpse. Resolving follows, as repeated observation ripens into an unshakeable conviction that the body is indeed impure, a settled understanding rather than a passing impression. And releasing the mental aspect comes last, because true wisdom must not remain fixed even on a correct image: reflecting further that this impurity depends on the body, and that the body itself, being merely the product of causes and conditions, has no fixed reality of its own, the practitioner lets go of the very image just resolved upon, so that neither the object observed nor the mind observing it is any longer grasped as something fixed. Master Cháng Bǎi then draws out five distinct methods by which this releasing is actually carried out in practice: turning the mind inward, alternating observation with calm-abiding so that insight and stillness take turns rather than insight running on without rest; non-attending, deliberately declining to dwell on the sounds, sights, or other sensory intrusions that might otherwise disturb the nine stages of mental abiding; redirecting attention, moving on from one stage of a contemplation to the next — from a corpse's discoloration, say, to its decay, and from decay to its swelling — releasing each image in turn to take up the one that follows; applying an antidote, taking up a specific contemplation as the direct remedy for a specific affliction, such as contemplating the six elements that compose the body to dissolve the conceit of "I" and "mine," and releasing that image once the antidote has done its work; and signless attention, the most complete release of all, in which the mind finally rests on no fixed characteristic whatsoever — neither straining after some further sign to grasp, nor sinking into the subtler error of clinging to "no sign" as though it were itself a sign to hold onto — a samādhi neither forced nor slack, which the treatise elsewhere calls the very door through which liberation is finally reached.

Master Cháng Bǎi distinguishes the four operations by depth and scope. Correct discernment examines a thing's exhaustive particulars in line with the Buddha's own teaching — its specific characteristics, considered one by one. Utmost discernment goes further, examining a thing's suchness — the universal marks it shares with everything else, impermanence, suffering, emptiness, and the absence of any self. Thorough investigation is the coarser, preliminary sweep either kind of discernment first makes; thorough examination is the finer, more sustained sweep that follows once the coarser pass is done — so that every act of discernment, whether aimed at particulars or at universals, actually unfolds through this same two-stage rhythm of a first broad pass and a deeper, more careful one. He notes this same fourfold movement is described elsewhere through a different lens, as three approaches and six bases — contemplation that simply follows the image's characteristic, that follows a preliminary investigation of it, or that follows a sustained examination of it, applied respectively to a thing's meaning, its concrete instance, its mark, its category, its time, and its underlying principle — different vocabularies for one and the same discerning activity. He then unpacks the five names given to insight itself, showing them to be one faculty wearing five faces: forbearance is the settled conviction that comes once repeated contemplation has actually persuaded the mind — accepting, say, that the body truly is impure, no longer clinging to the ordinary reversed view of permanence, pleasure, self, and purity; delight is the aspiration and joy that arise on finding one's own understanding matches what the Buddha taught, fueling a wish to press further; wisdom is simply the discriminating capacity itself, at its most basic; seeing is that same capacity in its earlier, searching phase; and contemplation is its later, more thorough phase. None of the five is a separate faculty, Master Cháng Bǎi stresses — they are one and the same wisdom, named differently at different moments of its unfolding. With this, the treatise's account of skill in insight is complete, matching calm-abiding's own completion two sections earlier: a bodhisattva relies on the twelvefold scripture and an unrelinquished vow for awakening, cultivates single-pointed attention until pliancy brings calm-abiding to completion, and then, on that very basis, observes, resolves upon, and releases the resulting image through these same four operations and five names of wisdom — insight and calm-abiding trading off, each making the other possible, until both stand perfected together.

Master Cháng Bǎi places both questions within an earlier fascicle's sevenfold scheme of attention, of which only the first five apply before pliancy arises: attention discerning characteristics, still mixed with ordinary hearing and reflection rather than genuine meditative absorption; attention of resolute understanding, no longer so mixed, where real cultivation of calm-abiding begins in earnest; attention that removes the coarsest, upper grade of afflictions still to be countered; attention that gathers joy while removing the middling grade; and attention that examines whether the mind still stirs once those coarser layers seem calmed. Only the sixth, the uninterrupted attention that finally clears the subtlest remaining afflictions, and the seventh, arising the very instant after it, the attention of the fruit itself — where pliancy is actually achieved — complete the sequence. Everything short of that seventh stage, however genuinely it accords with calm-abiding or insight's own aim, is still only attention "in accord with" the practice, not the practice's own accomplishment; Master Cháng Bǎi reads the Buddha's careful refusal to call either of Maitreya's two cases "calm-abiding" or "insight" outright as guarding against a common error — mistaking real but still-preparatory effort for the finished attainment it is only pointing toward.

Master Cháng Bǎi resolves this apparent contradiction by separating what is attended to from how it is attended to. Calm-abiding and insight, in ordinary practice, share exactly one object: once a meditator has spent time discerning some meditative image through insight, that very image, when calm-abiding then rests upon it, already carries insight's settling power within it — which is why the passage calls it not merely an "image" but a "mind," since it is now an image saturated with the prior work of concentration. On the question of what each attends to, then, they are not different at all. Yet on the question of how each attends, they remain, in the very same breath, not simply identical either: insight attends to that image by discerning and analyzing it, while calm-abiding attends to the identical image without any such discernment, resting on it single-pointedly instead — and an "image accompanied by discernment" is precisely what calm-abiding, by definition, never takes as its object. He notes that practitioners in fact alternate constantly between the two rather than holding one exclusively — observing, then resting; resting, then observing again — so that at any given moment the object is neither wholly released, since calm-abiding continues to rest on it, nor wholly grasped through analysis, since insight is not, at that moment, actively discerning it. It is this same alternation, Master Cháng Bǎi notes, that sets up Maitreya's next question, which pushes the inquiry one step further: if calm-abiding and insight share their object so intimately, is the meditative image they share even different from the mind that perceives it at all?

Master Cháng Bǎi treats this exchange as one of the treatise's clearest demonstrations of consciousness-only teaching, unfolded through a genuine philosophical difficulty rather than asserted outright. The Buddha's first answer is direct: the meditative image and the mind observing it are not different, because the image is nothing but consciousness itself — whatever consciousness takes as its object is simply what consciousness has itself manifested, the way a dream's content is nothing but the dreaming mind's own activity. Maitreya presses the natural objection: if they are truly not different, how does the mind manage to see itself, when nothing else — an eye seeing itself, a knife cutting itself, a fingertip touching itself — ever does? The Buddha's answer denies the premise buried in the question: there is, strictly, no dharma that sees any other dharma at all — not because nothing is seen, but because "seeing" here never involves two separate things, one seeing and one seen. Rather, the very arising of the mind in a certain way is, simultaneously, the very arising of the image's appearance; the two are not sequential events, one causing the other, but a single occurrence described from two angles. The mirror simile then makes this vivid: a person looking into a flawless, clean mirror takes their own face as a condition and sees that same face reflected back, yet mistakenly imagines that some further image, separate from the face, is appearing inside the mirror — when in truth the reflection has no existence apart from the face at all; remove the face, and the reflected image simply disappears, because it was never a second thing to begin with. Master Cháng Bǎi notes Master Woncheuk's gloss of "face" as the mind's own essence and the mirror as its seeing aspect, so that the reflected image stands for its seen aspect — one mind, dividing itself in appearance into a seer and a seen the instant it stirs, the way a single flame throws both light and heat without ever being two things. Just so, he explains, when a meditator contemplating a corpse's impurity generates that impure image in absorption, the image only "seems" different from the observing mind — a semblance of otherness, not an actual otherness — because apart from that very mind's own activity of discrimination, no impure image exists anywhere to be found; it has no independent nature of its own, present only exactly when, and exactly because, the mind discriminates in just that way.

Master Cháng Bǎi reads Maitreya's final question here as making sure the mirror simile is not mistaken for a special truth about meditators alone: what about beings who have never practiced at all, whose five senses simply take in form, sound, and the rest in the ordinary run of daily life — is the same principle still true of them? The Buddha's answer extends the teaching without qualification: yes, without any difference at all. The gap between a meditator's insight and an ordinary being's confusion, Master Cháng Bǎi stresses, was never a gap in what is actually the case — it was always true, for every being at every moment, that whatever is perceived is nothing but consciousness manifesting itself — but only a gap in whether that fact is recognized. Ordinary beings, carrying accumulated ignorance and grasping at self and at things since beginningless time, take what consciousness itself has produced to be something existing outside and apart from mind, mistaking it for real, external objects utterly independent of the perceiving mind — a distorted understanding no different in kind from the mirror-gazer's mistake, only unexamined and so unrecognized as a mistake at all. He draws out the practical weight of this teaching with a classical illustration: a person with a smudge of ink on their own nose looks into a mirror, sees the smudge reflected there, and blames the mirror for being dirty, scrubbing at the glass instead of their own face — no amount of polishing the mirror will ever remove a mark that was never on the mirror to begin with. Just so, he says, when a person meets another's faults, likes, or dislikes and feels resentment rise, that resentment is aimed at what is, in truth, nothing but the resentful person's own mind appearing to itself; time spent trying to change the external world accordingly is time misspent, and it is only through cultivating calm-abiding and insight to eliminate one's own distorted discrimination — turning consciousness into wisdom — that affliction can actually be uprooted, since as the mind is purified, so too is what appears to it. With this, the treatise's inquiry into whether the seen image and the seeing mind are the same or different is fully closed, extended from the specific case of meditative practice to the whole of ordinary experience, and the discussion turns next to how calm-abiding and insight can be practiced exclusively, or jointly, in a single sitting.

Master Cháng Bǎi distinguishes the three modes cleanly. Exclusive insight is unbroken, continuous discernment — the fourfold operation of correct discernment, its utmost form, and their coarser and finer investigations — applied without interruption to the mental image, the object insight itself produces. Exclusive calm-abiding is unbroken, continuous rest — the mind simply attending, moment after moment, to the same "uninterrupted mind" without any further analysis, each moment resembling the one before it, like water flowing evenly rather than churning. Joined operation is reached only once one no longer needs to alternate between the two at all: insight itself becomes effortless, spontaneously yielding calm-abiding's settledness, and calm-abiding becomes fertile ground from which insight arises without further deliberate effort — an earlier fascicle requires, at minimum, the ninth and final stage of mental abiding, full absorption, as the basis from which this wisdom then operates spontaneously, undistracted, unclouded by the ten obstructive signs or the five hindrances, borne along by concentration's own stability rather than driven by continued exertion. He supports this threefold distinction with two classical formulas: the Cloud of Jewels Sūtra's "calm-abiding is one-pointedness of mind; insight is correct examination," and a verse attributed to Maitreya himself — "gathering the names of every dharma, know this as the path of calm-abiding; discerning the meaning of every dharma, know this as the path of insight." He adds an important clarification some readers miss: both calm-abiding and insight can take either conventional truth's exhaustive particulars or ultimate truth's suchness as their object, so the difference between the two was never about which truth is contemplated — a mind can rest undistracted on emptiness itself, or discern and analyze the plainest conventional fact — but strictly about how the mind engages whatever it contemplates, resting without distraction or discerning through analysis.

Master Cháng Bǎi treats this exchange as clarifying two terms the previous section had already used without fully defining. The "mental image" simply names insight's own object, the image accompanied by discernment already introduced earlier in the chapter. The "uninterrupted mind" names calm-abiding's own object — that very same image, but now taken up by a mind that rests on it moment after moment without any break in continuity, each successive moment resembling the one before it with no discriminating activity interposed between them; it is this seamless continuity, rather than any difference in content, that earns it the name "uninterrupted." He flags an important distinction the Reflections on the Categorized Verses insists on: this is not the same as insight's own ever-shifting image, since insight's object keeps changing as analysis proceeds from one aspect to the next, while calm-abiding's object is that same image held motionless, without alternation, once analysis has done its work. He returns to the corpse's impurity as illustration: insight first analyzes the discoloration through its fourfold operation, and only once that analysis has yielded genuine resolve does the practitioner release further discernment and simply rest the mind on that same, now-unchanging image — this resting alone is calm-abiding proper. He revisits, too, an earlier fascicle's painter's analogy for how the two are meant to alternate in practice: a painter dissatisfied with a sketch tears it up and starts again on a fresh sheet rather than piling more strokes onto a ruined canvas, since repeated additions only smear it further into a formless smudge; just so, a meditator observes for a time, then releases that observation and rests in calm-abiding to let the mind settle and clear, before taking up observation once more on a mind now more lucid than before — insight and calm-abiding trading places again and again, each cycle leaving the mind a little clearer than the last, until the two no longer need to alternate at all.

Master Cháng Bǎi reads this answer as unfolding across two stages, one still contaminated and one finally uncontaminated. In the first, corresponding to the stages of heat and summit among the four aids to penetration, a bodhisattva applies the fourfold investigation into a thing's name, its concrete instance, its own-nature, and its particular features, coming to realize that everything grasped as an external object — the very teaching that opened this chapter's mind-only demonstration — has no existence apart from consciousness itself; calm-abiding and insight are already joined here, but the realization achieved is still contaminated, not yet the breakthrough of the path of seeing. In the second stage, corresponding to forbearance and supreme mundane dharma, the same bodhisattva presses further: not content with knowing that the grasped object is empty, he comes to know with equal certainty that the grasping consciousness itself is, just as decisively, without any real existence of its own — object and subject empty together, neither one left standing as a final, ungrounded reality — and in a single, uninterrupted instant, this joined realization carries him across into the path of seeing itself, where the perfected nature is directly and non-conceptually realized. With this, calm-abiding and insight are no longer two practices taking turns but a single, indivisible gnosis, and the treatise's threefold account of exclusive insight, exclusive calm-abiding, and their joined operation — the latter itself unfolding from a still-contaminated preliminary stage to its final, uncontaminated consummation — comes to a close.

Master Cháng Bǎi reads these three as marking successive depths of the same discerning activity. Marked-out insight is the shallowest: purely bringing a verbal or conceptual image to mind through the power of prior hearing, without yet weighing, measuring, investigating, or examining it — thinking a phrase and simply letting its image appear, corresponding to the earlier fourfold operation's initial, coarser sweep still mixed with hearing and reflection. Inquiring insight goes further, turning coarser investigation onto whatever object among the standard objects of practice — impurity, loving-kindness, dependent origination, elemental analysis, breath-mindfulness, skillful analysis of the aggregates, elements, sense-fields, and dependent origination, or the objects proper to purifying affliction, whether mundane or supramundane — is not yet fully grasped, working to understand its exhaustive particulars, its concrete instances and specific marks. Examining insight goes deeper still, turning the same investigation onto an object already well understood, now examining its universal characteristics — impermanence, suffering, emptiness, selflessness, shared across its unwholesome and wholesome aspects, across past, present, and future, and confirmed through the four modes of reasoning — with the specific aim of actually uprooting affliction's own seeds, reaching what the treatise elsewhere calls the accomplishment of what is to be done: the transformation of basis in which every seed of coarse affliction stored in the eighth consciousness is finally stilled, and non-conceptual direct gnosis of the known thing itself arises in its place. Master Cháng Bǎi also draws a distinction the source material insists on: the "known thing" itself is whatever ordinary cognition, through the eyes and the other senses, actually perceives before meditation begins — a corpse's impurity, say, as directly seen; the "counterpart image" is what appears within meditative absorption once resolute understanding has arisen through concentration's power — closely resembling, but not identical with, the object originally perceived, the way what is seen with eyes closed in visualization resembles, without literally being, what was earlier seen with eyes open. With these three, the treatise's account of insight's varieties is complete: shallow to deep, marked-out to inquiring to examining, culminating in single-pointed union with calm-abiding once genuine liberation is reached.

Master Cháng Bǎi explains the threefold count first: since calm-abiding is always practiced on the very "uninterrupted mind" that insight's three grades each produce, calm-abiding naturally divides into the same three — one following marked-out insight, one following inquiry, one following examination. He then unpacks the eightfold count through the Abhidharma-mahāvibhāṣā-śāstra's own test for what counts as a true meditative absorption (dhyāna) at all: a state must be capable both of severing the fetters below it through reflective investigation and of clear, correct observation through stillness — desire-realm concentration can observe clearly but cannot sever fetters, while the four formless attainments can sever fetters but cannot observe clearly, so neither, strictly, counts as dhyāna; only the four form-realm absorptions hold stillness and reflection in balance, earning the name. Together with the four formless attainments — boundless space, boundless consciousness, nothing whatsoever, and neither perception nor non-perception, each possessing stillness without discursive reflection — this yields eight distinct states, each its own calm-abiding. The fourfold count follows the four immeasurable states: loving-kindness, which contemplates bringing ease to beings without joy or sorrow; compassion, which contemplates removing suffering from beings in pain; sympathetic joy, which rejoices in the happiness beings already have and wishes it to continue; and equanimity, which lets go of the residue of favoritism running through all three of the others — each, settled into its own absorption, likewise counting as its own distinct calm-abiding. Master Cháng Bǎi notes the text stops enumerating at four not because the list is complete, but because the same logic extends without limit: since insight can be turned toward countless different objects, calm-abiding, always following insight's own object, admits of countless kinds in turn — three, eight, and four are simply the most commonly named divisions, not an exhaustive census.

Master Cháng Bǎi reads this distinction as turning not on what is practiced but on where the practice comes from. A bodhisattva who follows the Dharma draws calm-abiding and insight directly from the characteristics of a teaching received and reflected upon through their own study of the twelvefold scripture, needing no further instruction from anyone else to put it into practice and reach realization; a bodhisattva who follows faith reaches the very same attainments — the same contemplation of a corpse's discoloration or decay, the same recognition that conditioned things are impermanent and suffering, that all dharmas are without self, that nirvāṇa is utterly quiescent — but only by relying on a teacher's personal instruction and guidance, without that capacity to draw it out from the texts unaided. He cross-references an earlier fascicle's definitions almost verbatim: one who follows the Dharma has, in what has been heard, received, thoroughly investigated, reflected upon, weighed, and observed, sufficient power and capacity to practice accordingly without seeking any teacher's instruction; one who follows faith must first seek out a teacher's instruction and guidance, and practices only by the strength of faith in that teacher, lacking the independent capacity to proceed from the teaching alone. The same two terms, he notes, describe the śrāvaka path's own entry-level distinction at the path of seeing — dull faculties there are also called followers of faith, sharp faculties followers of the Dharma, later maturing respectively into resolute understanding and having-arrived-at-seeing as practice deepens — and some commentators map the same pair onto the bodhisattva path's earlier stages, with the stage of provisions corresponding to following faith, not yet self-sufficient in concentration and wisdom, and the stage of preparatory effort corresponding to following the Dharma. Master Cháng Bǎi is careful to note that "sharp" and "dull" here describe a difference in method available at a given point in practice, not a fixed, permanent trait — a follower of faith who keeps studying can, in time, become capable of following the Dharma directly.

Master Cháng Bǎi contrasts a bodhisattva who takes some single scripture or treatise — a particular sūtra on breath-mindfulness, a particular philosophical treatise — as the whole basis of practice, with one who has studied broadly across many texts and now gathers all of it together without distinguishing one teaching from another. He explains the four near-synonymous gathering terms as views from slightly different angles on the same totalizing move: a single mass, no longer distinguishing form from mind, since both alike are impermanent, suffering, empty, and without self; a single accumulation, no longer distinguishing among the aggregates' own countless varieties, since feeling's many kinds, or perception's, all reduce equally to suffering; a single category, no longer distinguishing the lower fetters from the higher, since both alike must be cut; and a single aggregate, no longer distinguishing form from mind in their gathered totality — four different words circling the same point: refusing to analyze differences among teachings, and instead directly apprehending the single universal characteristic every one of them, without exception, discloses. He then traces the threefold graded reflection — according with, moving toward, and arriving at — through the three levels of wisdom: hearing-wisdom's distant approach, simply recognizing suchness's mark without yet penetrating it; reflection-wisdom's middle approach, weighing and confirming this understanding until it becomes an unshakeable resolve no longer moved by other views; and cultivation-wisdom's close approach, where meditative absorption finally carries the practitioner to the very threshold of realizing suchness directly, the uncontaminated root wisdom of the path of seeing. This same threefold movement, he notes, applies equally to suchness's three fruits: awakening, the wisdom attained as a conditioned result; nirvāṇa, the unconditioned reality realized through it, which the tradition names in dozens of ways — inherently pure by nature, with residue still remaining, without any residue at all, or, reserved for buddhahood alone, abiding nowhere between saṃsāra and quiescence; and the transformation of basis, consciousness itself turned into wisdom, the fruit of the Dharma-body. A bodhisattva who reflects in this gathered, totalizing way on the boundless wholesome dharmas every scripture proclaims is said to take the totality of the teaching as the object of calm-abiding and insight alike.

Master Cháng Bǎi reads these three as an escalating scope of the very same gathering practice already introduced. The small totality applies the gathering method to just one scripture or treatise at a time — still, in effect, an individual teaching, only now approached through the totalizing method rather than analyzed in its own particular terms. The great totality applies the same gathering method across the whole of everything a bodhisattva has personally studied, no longer distinguishing text from text at all, drawing on every sūtra, every discourse, every treatise encountered over years of learning as a single, undivided object. The immeasurable totality goes further still, beyond even one's own personal store of learning, to the boundless teachings of buddhas without number throughout the ten directions and three times, the inexhaustible phrases and words in which the Dharma has ever been or could ever be spoken, and a wisdom that keeps deepening without any final limit — Master Cháng Bǎi cites Master Woncheuk's threefold gloss on why this counts as "immeasurable": immeasurable because what is taught is itself boundless, immeasurable because the buddhas who teach it are themselves without number, and immeasurable in both senses combined. He notes this final, most expansive object calls on what the tradition names the four kinds of unhindered understanding — unhindered understanding of the teaching's own terms, of the meaning those terms express, of language itself in all its varied expression across peoples and tongues, and unhindered eloquence in expounding what has been understood — and that reaching it in its fullness is explicitly described as the domain of advanced bodhisattvas, traditionally placed at the ninth ground, where all four kinds of understanding operate without any remaining obstruction at all.

Master Cháng Bǎi maps these five signs onto five specific bodhisattva grounds, each the fruit of one of five modes of cultivation an earlier fascicle names. The first, the moment-by-moment melting away of coarse obstruction's seeds, belongs to the first ground, utmost joy, the fruit of the "gathering" mode of cultivation that draws every teaching into a single totalizing object. The second, freedom from conceptual proliferation and the attainment of what the Compendium of the Great Vehicle calls the joy of the Dharma-garden, belongs to the second ground, freedom from defilement, the fruit of the "signless" mode, which lets go of every distinction within the undivided reality it contemplates. The third, comprehending the Dharma's boundless light without any difference across the ten directions, belongs to the third ground, radiance, the fruit of the "effortless" mode — and it is specifically at this ground, as the very next exchange makes clear, that this object is said to be truly attained rather than merely penetrated. The fourth, the non-conceptual mark now constantly present without needing to be summoned, belongs to the eighth ground, immovability, the fruit of the "vigorous" mode — since every ground before the eighth still requires some exertion to call this mark forth, while from the eighth onward it simply remains, uninterrupted. And the fifth, still gathering ever more excellent causes toward the Dharma-body's full consummation, belongs to the ninth ground, excellent wisdom, the fruit of the "never-satisfied" mode — for even at this advanced a stage, buddhahood itself has not yet been reached, and a bodhisattva must not rest content until it is. Together, these five landmark grounds — first, second, third, eighth, and ninth — trace the whole arc of mastering the totality of the teaching as an object of calm-abiding and insight, from its first breakthrough to its final ripening into the Dharma-body itself.

Master Cháng Bǎi distinguishes "penetrating" from "attaining" as two different thresholds along the same path. The first ground already breaks through to a genuine realization of the suchness underlying every teaching gathered into a single object — this is penetration, real but not yet complete. Only at the third ground, where the boundless light of the Dharma is comprehended without any difference across all ten directions, does this realization become full and rounded enough to be called attainment proper. Master Cháng Bǎi closes this entire topic with a word of encouragement he clearly wants his own students to take to heart: even a bodhisattva who has only just begun — still prone to the dullness and agitation, the drowsiness and distraction that plague every beginner's meditation — is nonetheless already applying the mind in this same fundamental way, following this same training from the very first sitting. Such early effort is not yet anything to be praised, since its fruits are still far off, but this is no reason to grow lax or give it up; as water wears through stone only by falling drop after drop without pause, sustained practice, however unimpressive at the outset, eventually bears its fruit. With this encouragement, the treatise's entire account of individual versus total, and small, great, and immeasurable scope, in the object of calm-abiding and insight, comes to a close.

Master Cháng Bǎi identifies examination (vitarka) and analysis (vicāra) as two grades of investigative mental activity — examination the coarser, initial casting of attention onto an object, analysis the finer, more sustained inquiry that follows — both ultimately grounded in the mental factors of intention and wisdom, differing only in coarseness and subtlety. He maps the three resulting absorptions directly onto three actual levels of meditative attainment: the desire realm and the first form-realm absorption still carry coarse examination and analysis together; the "intermediate dhyāna" lying between the first and second absorptions — the level from which one is reborn as the great Brahmā — has let go of coarse examination but retains a subtle, sustained analysis, described here as observing through "the light of mindfulness," a term an earlier fascicle glosses in up to four senses (the light of the teaching itself, of its meaning, of calm-abiding, and of insight), essentially the mind's own unclouded clarity when no discursive thought disturbs it; and the second absorption and everything above it, through the formless attainments, are free of both, examination and analysis alike having fallen away entirely. Master Cháng Bǎi notes this is explicitly framed as only the first of two readings the passage will offer — one grounded in the literal architecture of contaminated meditative absorption, with a second, quite different reading of the same three terms still to come.

Master Cháng Bǎi reads this second interpretation as taking the very same three terms and applying them along an entirely different axis — no longer the literal levels of meditative absorption, but the stages of a bodhisattva's own progress toward realization. "Examination and analysis together" now corresponds to inquiring insight at the stages of heat and summit among the four aids to penetration, where the fourfold investigation into a thing's name, its concrete instance, its own-nature, and its distinguishing features is still actively underway, seeking to understand what is not yet fully grasped. "Analysis alone" corresponds to examining insight at the stages of forbearance and supreme mundane dharma, where the fourfold true wisdom now confirms, with settled conviction, what that earlier inquiry had found, no longer searching but simply examining more finely what is already substantially understood. And "neither examination nor analysis" corresponds to calm-abiding and insight that take the totality of the teaching as their object — the gathered, undifferentiated object described in the treatise's immediately preceding topic — where discursive investigation of any kind has given way entirely to a bodhisattva's own uncontaminated wisdom operating on the grounds themselves. Read together with the first interpretation, Master Cháng Bǎi suggests, both readings trace the identical underlying arc — from coarse investigation, to fine investigation alone, to investigation's complete stilling — one mapped onto the architecture of meditative absorption itself, the other onto the path that leads through and beyond it.

Master Cháng Bǎi treats these three signs as the practical toolkit for steering the mind through meditation's two besetting faults. When agitation arises, or threatens to, the antidote is calming: deliberately reflecting on agitation's own drawbacks until it becomes something to be shunned, then returning the mind to that same "uninterrupted mind" already introduced earlier — the settled object calm-abiding rests upon without a break. When the mind instead sinks into dullness, or threatens to, the antidote is uplifting: turning the mind toward things that genuinely inspire joy, chiefly through what the tradition calls the six recollections — recalling the Buddha's ten epithets and boundless compassion and wisdom; the Dharma's own virtues, well taught, directly visible, timeless, inviting inspection, leading onward, and to be known by the wise for themselves; the noble community's accomplishment in discipline, concentration, wisdom, and liberation; one's own efforts at pure ethical discipline; one's own generosity, given freely and without attachment; and the five qualities of faith, discipline, learning, generosity, and wisdom that lead toward a fortunate rebirth — each recollection lifting the heart the way encouragement rouses a flagging spirit, so that practice can continue. But once neither fault troubles the mind any longer, a third sign is needed, and it is subtler than the other two: equanimity, which is not a further technique applied to the mind but the release of technique itself — letting go of the very effort calming and uplifting required, and allowing the mind to function on its own, spontaneously, within whichever path it was pursuing, calm-abiding alone, insight alone, or their joined operation together. Master Cháng Bǎi closes with a caution an earlier fascicle draws out explicitly: a practitioner must apply all three signs at their proper times rather than favoring any one exclusively — one-sided calming or uplifting alone, however well executed, only ever keeps a practitioner at the level of preparatory method, while it is the timely alternation among all three, settling finally into equanimity once balance is genuinely reached, that carries the path to its completion and, through sustained investigation of dependent origination and the noble truths, to the actual exhaustion of the contaminants.

Master Cháng Bǎi opens a new inquiry here: alongside calm-abiding and insight's meditative technique, a bodhisattva must also know the Dharma itself and its meaning, and this passage supplies the first half — five aspects of knowing the Dharma. A name is simply the word attached to some dharma, defiled or pure — not inherent to the thing itself, but a provisional label the conceptualizing mind lays over it purely to make communication possible; he distinguishes three kinds — purely conventional names with no real thing behind them at all, such as "I" or "a vase"; names for things that genuinely exist through causes and conditions, such as "eye" or "form"; and names universally understood, such as "mountain" or "river," against specialized ones understood only by those trained in a particular field, Buddhist terminology among them. He grounds this in an earlier fascicle's terse definition of a name as "the shared, agreed-upon expression" — an "added-on term" laid over things that, in their own true nature, carry no name at all, needed only because ordinary life requires some way to talk about them. A phrase gathers names together to express what no single name alone can: the word "affliction" by itself says nothing about why affliction is a fault, but the phrase "affliction defiles the mind, drives one to create karma, and brings a fall after death" conveys the very point a single name could never carry — precisely the distinction the Establishment of Consciousness-Only Treatise draws in its own formula, that names denote a thing's essential nature while phrases denote its distinctions. A letter is simply the written or spoken character both names and phrases ultimately rest upon, the raw material out of which either is built. And knowing the particular and knowing the general, Master Cháng Bǎi notes, directly echo the individual and total objects of practice introduced several sections earlier: knowing the particular is attention that takes up each teaching separately, coming to understand exactly what distinguishes the four foundations of mindfulness from the four right efforts, for instance; knowing the general is attention that gathers every teaching together as one object, converging on the single truth every particular teaching, however different its specific content, ultimately discloses — suchness itself, present without difference beneath the whole, bewildering variety of the Buddha's teaching. With the Dharma's five aspects now named, the treatise turns next to what it means to know the meaning those very names, phrases, and letters exist to express.

Master Cháng Bǎi closes "knowing the Dharma" by noting that its five aspects — name, phrase, letter, particular, and general — are meant to be grasped together as a single, integrated skill, not five separate exercises: a bodhisattva who studies scripture carefully, he says, should mark every unfamiliar term while reading, look it up, and test whether the resulting sense of a passage actually holds together, exactly the discipline earlier translators and reciters were famous for bringing even to the pronunciation of a single syllable. He then turns to "knowing the meaning," unpacked here through ten aspects that together span the whole of what a bodhisattva must understand: the exhaustive particulars and suchness of things, first; then what grasps and what is grasped, the meaning of the world's own structure and of how beings make use of it, the four kinds of reversal and non-reversal that mark deluded and undeluded understanding, and finally defilement and purity themselves. He explains the exhaustive particulars as the complete classification of any topic down to its last subdivision — the five aggregates admit of nothing outside themselves, since there is no form apart from the aggregate of form, and the twelve sense-fields, six inner and six outer, likewise leave nothing further to add — so that knowing the exhaustive particulars of a topic means knowing that its classification is complete, with no remainder outside the scheme given. Suchness, by contrast, is what does not vary with classification at all: the single, unconditioned reality present equally within every defiled dharma's conventional truth and every pure dharma's ultimate truth alike, called here sevenfold not because suchness itself has seven parts, but because seven distinct approaches to dependent origination each disclose the very same single reality from a different angle — Master Cháng Bǎi flags that the treatise is about to work through each of these seven approaches in turn, in enough depth that the coming sections will need to slow down and take them one at a time, since suchness understood this way, threading through both what changes and what never changes, is the single thread that ties every other one of the ten aspects of knowing the meaning back together.

Master Cháng Bǎi treats these seven not as seven different realities but as seven angles on the one, undivided suchness, each disclosed by considering dependent origination from a different vantage. The suchness of continuous flow is what remains true of conditioned activity's endless arising and ceasing, moment after moment: no discoverable first beginning, no final last end, only cause conditioning effect and effect in turn conditioning further cause, the way asking whether the chicken or the egg came first turns out to be an idle question rather than a real one — and, crucially, no fixed self is doing the flowing and no fixed dharma is what flows, since the very flowing is itself empty, dependently arisen, and without any real self at its core. The suchness of characteristics is the twin emptiness of self and of dharmas: ordinary beings either cling to a real, independently existing person and real, independently existing things, or else collapse into denying everything as sheer nothingness, and both extremes are avoided the moment one sees that the imagined characteristic projected onto experience is simply not there at all, while what that projection is laid over — the dependent and the perfected — is not simply not-there either; this middle path, avoiding both naive existence and naive nonexistence, is what "the suchness of characteristics" names. The suchness of discernment is the mind-only teaching already demonstrated earlier in this very chapter through the mirror simile: nothing is ever experienced apart from consciousness's own manifesting of it, and realizing this thoroughly — first as an idea to be verified during the stage of preparatory effort, then directly, non-conceptually, at the path of seeing itself — is what this third suchness discloses. The remaining four turn to the four noble truths, each understood not merely as a doctrinal claim but as a reality in its own right: the suchness of what is established is suffering's own real, inescapable unsatisfactoriness running through all conditioned existence, deeper than mere pain — the very fabric of the round of rebirth, felt as coarseness, rigidity, obstruction, timidity, and a body and mind without any capacity for what is wholesome, wherever the fundamental consciousness that stores affliction's own seeds is present; the suchness of wayward conduct is affliction and the karma it drives being just as empty and dependently arisen as everything else — and it is exactly this emptiness that makes their uprooting possible at all, since were craving and karma truly, independently real, no being could ever hope to escape them; the suchness of purity is nirvāṇa's own utterly unstained reality, the complete extinguishing of both the afflictive and cognitive obstructions; and the suchness of right conduct is the true reality that every genuine practice of the path — the eightfold path chief among them — ultimately rests upon and leads toward. Master Cháng Bǎi notes the sevenfold sequence itself moves from the most general to the most specific: first, conditioned activity in general; second, all dharmas in general; third, consciousness specifically; fourth and fifth, the contaminated, worldly side of experience, suffering and its cause; sixth and seventh, the uncontaminated path to liberation, its fruit and its means — a single survey of reality narrowing, truth by truth, down to exactly what frees a being from suffering. And the way into any of the seven, he stresses, is the same middle path this whole chapter has been tracing throughout: neither asserting that what is conventionally named truly exists as named, nor denying that the reality underlying the name exists at all — avoiding both extremes is what discloses suchness, called for this very reason the middle way, free of both extremes, and unsurpassed.

Master Cháng Bǎi reads this as the treatise's own summary of what the seven suchnesses, taken together, actually deliver: four distinct kinds of equality. The first three suchnesses — continuous flow, what is established, and wayward conduct — together show that all beings are equal, since every being's round of birth and death, however different its particular karma, is equally empty, equally without any discoverable beginning or end, and equally without a real self driving it forward; beings differ endlessly in the specific unfolding of their affliction, karma, and suffering, but not at all in the fundamentally empty, dependently arisen nature underlying that unfolding. The next two — characteristics and discernment — show that all dharmas are equal, since every dharma without exception is equally empty of the imagined nature falsely projected onto it and equally nothing but consciousness's own manifesting; Master Cháng Bǎi cites the Madhyānta-vibhāga's own formula for this — "the imagination of the unreal exists; within it, the twofold division does not; yet emptiness itself exists within this very imagination, and this imagination equally exists within that very emptiness" — as the classical statement of why grasped and grasper, however really they seem to appear, share one and the same empty ground. The suchness of purity shows that liberation itself is equal across every vehicle: a śrāvaka's arhatship, a pratyekabuddha's awakening, and a buddha's own unsurpassed awakening all realize the identical, undivided suchness of nirvāṇa — differing only in what further, unshared qualities accompany the realization, a buddha alone possessing the ten powers and the rest, never in the quality of the liberation from affliction itself — which is exactly what licenses the tradition's image of all three vehicles sharing one single bed of liberation. And the suchness of right conduct shows that the very process of reaching any of this — hearing the true teaching, reflecting on it, and cultivating it through calm-abiding and insight that take the totality of the teaching as their object — is itself equal for every practitioner regardless of vehicle, since whoever actually reaches liberation does so by walking this same threefold path of hearing, reflection, and cultivation, with no shortcut around it for anyone.

Master Cháng Bǎi unpacks "what grasps" as everything standing on the subject side of cognition: the five physical sense-faculties, eye through body, which serve as the basis for the five sense-consciousnesses; mind, the eighth consciousness, which manifests the body, the surrounding world, and the seeds from which all experience grows; intellect, the seventh consciousness, which clings to the eighth consciousness's own seeing-aspect as an inner self, generating the view of self, self-conceit, self-love, and self-delusion; and consciousness, the six consciousnesses, which discern their respective objects and generate craving toward what is pleasant, aversion toward what is unpleasant, and confusion toward what is neither — together with the many mental factors, universal, object-determining, wholesome, or afflictive, that accompany each act of discernment depending on whether attention is applied correctly or distortedly. "What is grasped" is the six outer objects these faculties and consciousnesses take up — form, sound, smell, taste, touch, and mental objects. But the passage's final clause matters as much as the definitions themselves: what grasps can equally become what is grasped, since the mind can turn back and take its own faculties, its own consciousness, even its own mental factors, as a further object of cognition — the categories are not two separate territories but two roles the same dharmas can play depending on how the mind is currently engaging them. Master Cháng Bǎi draws out the practical stakes with a well-known image: the six sense faculties are like six gates through which six thieves — the six sense objects — enter and plunder a household's wealth, robbing a being of the store of merit built up over lifetimes; only mindfulness, standing guard at each gate, and wisdom, discerning what genuinely helps from what genuinely harms, can keep this theft from continuing unchecked, and it is exactly by seeing that neither the grasped object nor the grasping mind has any fixed, findable reality of its own that a practitioner finally stops the thieves from finding anything left to steal at all.

Master Cháng Bǎi walks this scale up level by level: a village's fields; landmasses reaching to the ocean's edge; the continent of Jambudvīpa itself, distinguished in an earlier fascicle from the world's three other continents by shape alone, Jambudvīpa cart-shaped, its eastern neighbor half-moon shaped, its western neighbor full-moon shaped, its northern neighbor square, with the inhabitants of each said to take on their own continent's characteristic form; the four continents together; a small-thousand world-system, one thousand sun-and-moon systems each with its own Mount Sumeru, reaching up through the first meditative heaven; a medium-thousand system, one thousand small-thousand systems, reaching to the second; a great-thousand, three-thousandfold system — not three separate great-thousand systems, but one thousand medium-thousand systems compounding the small and medium scales beneath it — reaching to the third; then koṭis, hundred-millions; asaṃkhyeyas, numbers beyond ordinary counting; and finally a scale measured not in world-systems at all but in the number of fine motes of dust countless such systems would contain if ground down completely. A bodhisattva absorbed in deep meditation, Master Cháng Bǎi notes, must be able to survey this entire scale directly, from the smallest inhabited village up through world-systems beyond any possible count — a capacity ordinary beings reach today only through instruments and calculation, but which meditative power once made directly present to sight. He closes on the teaching's real point: every physical realm arises exactly tracking the karma of the beings who come to inhabit it, so that even beings sharing the same city or the same house can experience utterly different qualities of the same place depending on their own individual karma — which is exactly why a bodhisattva who wishes to see a land made truly excellent must first purify their own mind, since as the mind is purified, so too, inevitably, is the land it comes to inhabit.

Master Cháng Bǎi explains the meaning of what is enjoyed through the ten requisites of life an earlier fascicle names — food and drink, transport, clothing, ornaments, entertainment, fragrance and garlands, household goods, lighting, and the rest — and traces their ultimate source back to generosity: whoever hoards resources without using them loses them entirely at death, whoever simply consumes or wastes them loses them just as surely, but whoever gives some portion into a genuine field of merit reaps future abundance in return, which is why the Buddha is said to teach the practice of giving before any other topic, since the mere ability to survive and pursue any further practice at all depends on it. He then works through the fourfold reversal at the root of ordinary delusion — mistaking the impermanent for permanent, suffering for pleasurable, the impure for pure, and what has no self for having one — each operating in three successive layers: a reversal of perception, the initial misreading of what is actually there; a reversal of mind, the craving or aversion that misreading then stirs up; and a reversal of view, the settled, entrenched conviction eventually built on top of both. An earlier fascicle correlates each layer with specific afflictions — identity-view underlying the self-reversal, an extreme view of eternalism underlying the permanence-reversal, clinging to views underlying the purity-reversal, and clinging to rules and vows together with craving underlying the pleasure-reversal — and Master Cháng Bǎi notes that the meaning of what is not reversed is simply this entire structure inverted: the four foundations of mindfulness' own wisdom, seeing impermanence as impermanence, suffering as suffering, impurity as impurity, and no-self as no-self, directly countering each layer of the corresponding delusion. The meaning of defilement he unpacks as three interlocking defilements running through all three realms — the afflictions themselves, disturbing the mind (a topic the treatise elsewhere analyzes across nine separate dimensions, down to a full inventory of twenty-six distinct terms for affliction and its many consequences); the karmic action, bodily, verbal, and mental, that affliction drives a being to commit; and the resulting rebirth itself, which in turn breeds further affliction and further karma, keeping the whole cycle turning without any built-in end. Against this stands the meaning of purity: the thirty-seven factors of enlightenment — the four foundations of mindfulness foremost among them — which alone free a being from bondage to all three defilements at once. With these ten aspects complete, Master Cháng Bǎi closes by noting they are said to comprehensively include every kind of meaning that exists: nothing in the entire forward current of saṃsāra or its reverse current back toward nirvāṇa falls outside this tenfold scheme, and it is this completeness that lets the treatise now turn to restating the very same ground through fewer and fewer categories still.

Master Cháng Bǎi frames this second, fivefold scheme as covering the same ground as the ten aspects just closed, only reorganized around the shape of the path itself: an object to be known, its full meaning, the cause that leads to realizing it — the path itself — the fruit that realization yields, and, finally, full personal awakening to the whole of it, including the capacity to explain it fully to others. Comprehensively knowing the object simply repeats the aggregates and sense-fields already introduced as the exhaustive particulars, the raw material every other kind of knowing works on. Comprehensively knowing its meaning, though, opens into thirteen distinct ways of approaching that same material, and Master Cháng Bǎi works through each in turn. By way of the conventional and the ultimate: he distinguishes four ascending grades of each — the conventional running from the everyday world of houses and persons up through a bodhisattva's own two-fold emptiness expressed conventionally, the ultimate running from the aggregates and elements a sage understands through subsequent wisdom up to the single reality realized only by non-conceptual wisdom itself, beyond every one of the lower three tiers. By way of virtue and fault: genuine virtue belongs only to the pure, unconditioned qualities of buddhas and bodhisattvas, while the virtues ordinary beings cultivate remain conditioned and still capable of leading back into saṃsāra, and fault names the boundless harm the three defilements bring in their wake. By way of conditions: the four conditions any dharma may depend on — the causal condition of a seed itself, the immediately antecedent condition of one moment of mind clearing the way for the next, the objective-support condition of whatever a mind takes as its object, and the dominant condition of anything with the power to help or hinder another dharma's arising. By way of time: three distinct senses of past, present, and future — one tracking actual phenomena, one tracking consciousness's own projected sense of time, and one, available only through meditative power, that directly perceives times otherwise hidden from ordinary perception. By way of arising, abiding, and ceasing: the three marks any conditioned thing passes through, coming into being, persisting for a moment, and then falling away. By way of what is like a sickness and the rest: contemplating the five aggregates as a sickness, a festering wound, a deeply lodged dart, and an affliction — vivid images meant to break the ordinary complacency beings feel toward their own bodies. By way of suffering and the rest: the four noble truths' own inner logic, oppression, accumulation, quiescence, and the path that leads to it. By way of suchness, the ultimate limit of reality, and the realm of dharmas: three names for the identical single truth, distinguished only by the angle from which each name approaches it. By way of the extensive and the concise: the Buddha's own habit of teaching some listeners at great length and others through the barest summary, matched to whether a listener wants many details or only the essential principle — exactly the balance, Master Cháng Bǎi notes, this treatise itself strikes by pairing vast doctrinal elaboration with terse summary verses throughout. By way of the four kinds of answer: a categorical answer given outright, an answer that first distinguishes before answering, an answer that turns the question back on the questioner, and an answer set aside as unfit to answer at all — the classical fourfold typology of how a teacher may respond to any question put to them. And by way of the hidden and the openly revealed: the very distinction, Master Cháng Bǎi notes, that the second and third turnings of the Dharma wheel embody in miniature — the same reality first veiled behind a language of pure negation, and only later stated in a language that leaves nothing further concealed.

Master Cháng Bǎi identifies comprehensively knowing the cause as the thirty-seven factors of enlightenment — the four foundations of mindfulness, four right efforts, four bases of supernormal power, five faculties, five powers, seven factors of awakening, and the eightfold path — the very path that takes hold of the object already known and its meaning already understood, and turns that knowledge into realization. He stresses the distinctly Mahāyāna angle an earlier fascicle adds to these same factors: a bodhisattva practicing, say, mindfulness of the body does not simply contemplate its impurity in the śrāvaka's direct manner, but contemplates the body as neither truly existing the way ordinary clinging imagines it, nor as utterly nonexistent the way its own dependent and perfected nature must still be accounted for — the identical thirty-seven factors, walked through the very same middle path this whole chapter has traced from the beginning, rather than through the śrāvaka's more direct route alone. Attaining the fruit of comprehensive knowing, he explains, unfolds in two stages already familiar from a śrāvaka's own progress — first subduing affliction's active manifestation through discipline, then permanently cutting off its underlying seeds to reach the fruits of stream-entry through arhatship — but with a crucial bodhisattva twist: even a bodhisattva who fully understands how to eliminate every contaminant deliberately declines to bear witness to that cessation prematurely, remaining engaged with conditioned existence for the sake of benefiting others without being stained by it, and reserving full witness for the ultimate fruit of buddhahood itself, where the qualities shared with śrāvakas — freedom from affliction — are joined by the vast, unshared qualities belonging to a buddha alone. And awakening fully to all of this, Master Cháng Bǎi notes, is not private attainment alone but attainment turned outward: exactly as the Buddha, having reached unsurpassed awakening, did not keep the path to himself but explained the entire causal sequence in full so that others could walk it too, a bodhisattva who has genuinely realized liberating wisdom must, in turn, proclaim and reveal it broadly for the benefit of other beings. With these five aspects closed, Master Cháng Bǎi notes Maitreya's evident confidence carrying forward into what comes next: however many further frameworks the Buddha now offers — four aspects, and then three — each one, in its own way, will turn out to comprehensively cover this very same single field of reality, approached each time through a different number of gates.

Master Cháng Bǎi maps these four directly onto the four foundations of mindfulness. The meaning of what the mind appropriates corresponds to mindfulness of the body, since it is the mind that appropriates and animates the physical body in the first place; the Larger Prajñāpāramitā Sūtra has a bodhisattva reflect, from head to foot, that this body holds nothing but impurity, is without self, without lasting pleasure, impermanent and doomed to decay, bound together by sinew and vein, foul and rank — a reflection that dissolves both craving for the body and the view that clings to it as a self. The meaning of what is received corresponds to mindfulness of feeling, since feeling is precisely what is received in each moment of experience; the same sūtra has a bodhisattva recognize that every feeling is, at root, suffering, and that only the deluded reverse this into a perception of pleasure — a reflection meant to dissolve the reflexive chase after pleasant feeling that keeps saṃsāra turning. The meaning of what discerns corresponds to mindfulness of mind, since discernment is simply the mind's own defining activity; the sūtra pictures the mind as impermanent though mistaken for permanent, the root of every unwholesome destiny, spinning as fast as a whirling firebrand and as untrustworthy as a wild horse, so that whoever masters this one mind masters every dharma that mind gives rise to. And the meaning of defilement and purity corresponds to mindfulness of dharmas, since it is specifically in relation to dharmas — the standing possibility of clinging to a self within them — that defilement and purity are distinguished at all; the sūtra has a bodhisattva see that greed, hatred, delusion, and the rest of the afflictions arise only through attachment to what is, in truth, empty and illusion-like, dependently arisen without any real self at its core. Master Cháng Bǎi also notes an alternate reading some commentators favor, mapping all four instead onto the eighth consciousness alone — the ālaya as what appropriates the body and its seeds, what receives the manifested physical world, what discerns every realm however subtly, and what stores the seeds of both defilement and purity together — citing the Compendium of the Great Vehicle's own verse that this beginningless realm is the equal support of all dharmas, and that from it come both the various destinies of rebirth and the very realization of nirvāṇa. Either way, he says, these four aspects, tracking the four foundations of mindfulness precisely, comprehensively include every kind of meaning there is.

Master Cháng Bǎi treats this third and most condensed framework as circling back to the very starting point of the whole discussion of "knowing the Dharma" several sections earlier: the meaning of the text is simply the body of names, phrases, and letters already unpacked there — the linguistic vehicle a scripture is built from, necessary for conveying any teaching at all even though the vehicle itself is never identical with the truth it carries. He notes that this three-part scheme is about to unfold, in the passage now following, into first ten further sub-varieties of "the meaning of the meaning" — what the text's words actually point to — and only then a definition of "the meaning of the realm" closing out the third and final term; a bodhisattva who has followed the treatise's whole progression from ten aspects, through five, through four, arrives here at the most compressed statement yet of the same total field of meaning, three gates now standing in for what earlier took ten.

Master Cháng Bǎi identifies the first as the two truths themselves, worldly and ultimate, unpacked in an earlier fascicle into as many as six distinct grades of what counts as "truly real," from what is simply agreed upon by ordinary convention up to the reality realized only by wisdom purified of the subtlest cognitive obstruction. The next four map directly onto the four noble truths' own fourfold task: comprehensively knowing corresponds to suffering, which must be fully understood; permanently cutting off corresponds to origination, which must be eliminated at the root; bearing witness to corresponds to cessation, which must be directly realized; and cultivating corresponds to the path, which must be practiced and developed — the same four verbs the treatise has used throughout to describe how a practitioner actually engages each truth rather than merely believing it. The sixth is simply the specific subdivisions running through all of the above — the five aggregates' own distinct characteristics, say, within the broader category of suffering to be comprehended. The seventh concerns how what is depended upon and what depends on it relate to each other — the four great elements as the basis for derived form, the eye as the basis for eye-consciousness, a denoting word as the basis for what it denotes — bound up entirely with defilement before the transformation of basis is reached, and entirely with purity once it is. The eighth is whatever specifically obstructs comprehensive knowledge of the four truths — the afflictions themselves, or more specifically whatever obstructs the cultivation of the factors of enlightenment. The ninth is its precise opposite: whatever specifically accords with and assists that same comprehensive knowledge — the very wisdom that cuts through affliction, gained by diligently cultivating those same factors. And the tenth weighs the stakes of the whole matter: the manifold faults that follow from failing to comprehend, cut off, bear witness to, and cultivate the four truths — continued entanglement in the round of rebirth without end — against the manifold merits that follow from succeeding at all four, culminating in genuine liberation. Together, Master Cháng Bǎi notes, these ten characteristics complete "the meaning of the meaning," the second of the three terms — text, meaning, and realm — that make up this final, most compressed of all the frameworks the treatise has offered for knowing the meaning of what the Buddha teaches.

Master Cháng Bǎi identifies these five as the same five limitless objects an earlier fascicle calls a bodhisattva's five kinds of boundless attention. The physical world-system revisits, on a meditative rather than merely descriptive register, the cosmological scale already surveyed earlier in this very chapter, now understood as illusion-like, arising and passing through cycles of formation, endurance, decay, and emptiness, some realms defiled like this present world and some pure like a buddha's own land, all ultimately without any fixed, independent reality despite their vast and varied appearance. The realm of beings draws on an earlier fascicle's inventory of some sixty-two ways of classifying beings — by destiny, caste, sex, capacity, ordination status, ascetic practice, discipline observed or broken, meditative attainment, and spiritual lineage, whether fixed toward liberation, fixed away from it, or undetermined — so that a bodhisattva who would guide any being at all must first understand the full range of what a being can be. The realm of dharmas is everything the mind can take as an object, sorted through dozens of paired categories: form or formless, visible or invisible, offering resistance or none, contaminated or uncontaminated, conditioned or unconditioned, wholesome, unwholesome, or neutral, bound to the desire realm, the form realm, or the formless realm, belonging to one still learning, one beyond training, or an ordinary being neither — a bodhisattva's wisdom must range across every one of these distinctions without exception. The realm of what is to be tamed considers not dharmas in the abstract but the actual beings a bodhisattva sets out to guide, differing in lineage — śrāvaka, pratyekabuddha, or bodhisattva — in the sharpness of their faculties, the scope of their understanding, and the particular affliction, whether greed, hatred, or delusion, that dominates their temperament, since only knowing a listener this precisely lets a teaching actually land. And the realm of the skillful effort that tames them is the corresponding range of methods a bodhisattva must hold ready — gentle words for one listener, harsh rebuke for another, expulsion for a third, the display of supernormal power to inspire faith in a fourth, brevity for one question and elaborate explanation for the next — matched moment by moment to whichever being is actually being addressed. Master Cháng Bǎi closes by noting that a bodhisattva who has genuinely mastered both the exhaustive particulars and the suchness of these five realms can teach beings of every kind without exhausting their own resourcefulness, and can do so without ever clinging to a fixed notion of self, of another, of a being, or of a lifespan while doing it. With this fifth realm named, the entire discussion of knowing the Dharma and knowing its meaning — unfolded across ten aspects, then five, then four, and finally these three — comes to a close, completing the twelfth of Maitreya's questions to the Buddha in this chapter.

Master Cháng Bǎi walks through the same six marks across all three wisdoms to show a single, continuous deepening. On reliance on the text: hearing-wisdom cannot depart from the words at all, taking the meaning only as the text states it; reflection-wisdom still relies on the text but gains the power to judge which teachings are definitive and which merely provisional; cultivation-wisdom sometimes relies on the text and sometimes transcends it entirely, grasping the meaning directly without needing the words that first conveyed it. On taking things only as stated: hearing-wisdom cannot get behind the literal statement, while reflection and cultivation wisdom both can. On penetrating underlying intent: hearing-wisdom has not yet learned to hear what the Buddha left unstated between the lines — the treatise elsewhere catalogs as many as sixteen distinct kinds of such underlying intent — while reflection-wisdom and cultivation-wisdom both skillfully catch it; Master Cháng Bǎi illustrates the gap with the well-known story of the monk Fǎdá, who had recited the Lotus Sūtra three thousand times yet still bowed to the Sixth Patriarch with his head not quite touching the ground, betraying a hidden pride in his own recitation count — until the Patriarch's verse, "when the mind is deluded, the Dharma Flower turns you about; when the mind awakens, you turn the Dharma Flower instead," broke through to him in an instant what three thousand literal recitations alone had never delivered. On meditative presence: only cultivation-wisdom, grounded in genuine meditative absorption, brings the very image of the known thing vividly before the mind; hearing and reflection wisdom remain conceptual, however deep their understanding, because neither has yet achieved actual concentration. On according with liberation: hearing-wisdom, like a traveler still far from the shore, merely orients toward liberation from a distance, planting its seed; reflection-wisdom, discerning and subduing affliction through judgment, draws nearer still, sometimes closer and sometimes farther depending on how sustained the reflection is; and cultivation-wisdom, alone among the three, accords with liberation most fully of all, standing at the water's very edge. And on receiving and completing liberation's meaning: only cultivation-wisdom actually achieves this, since only it unites calm-abiding and insight in a single, joined operation capable of uprooting affliction's seeds rather than merely restraining their outward expression. Master Cháng Bǎi notes commentators across the tradition frame this same threefold progression in strikingly similar terms elsewhere — an early Abhidharma school's simile of a swimmer crossing a deep, fast river, clinging to a float at first, sometimes letting go and sometimes not as skill grows, and finally swimming free without any support at all — and closes by naming the practical stakes: a bodhisattva who mistakes hearing-wisdom's grasp of a teaching for the real thing, without ever pressing on to reflection and cultivation, remains permanently at the water's edge, however many times the words themselves have been recited.

Master Cháng Bǎi glosses the core distinction simply: wisdom takes hold of principle in its universal aspect, the gathered, undifferentiated suchness already introduced as the total object of practice, while seeing takes hold of a particular matter through the direct investigation of some individual teaching. He then draws out nine further distinctions an earlier fascicle offers between the two, note by note: wisdom knows what is not currently present, past and future, while seeing knows what is present before it now; wisdom takes the object grasped as its condition, while seeing takes the grasping mind itself as its condition; wisdom is produced through hearing and reflection, while seeing is produced through actual cultivation; seeing is what cuts affliction off, while wisdom is what, once affliction is cut off, goes on to realize liberation; wisdom takes a thing's own particular characteristic as its object, while seeing takes the universal characteristic shared across many things; wisdom engages the merely conventional designations laid over experience — a self, a being, an army, a forest, a house — while seeing grasps particular and universal characteristics more directly; wisdom is the initial searching investigation of a dharma, while seeing is the sustained examination that follows it; wisdom takes the image without discernment as its object, while seeing takes the image with discernment as its object; and seeing takes an image still bearing some trace of form as its object, while wisdom takes an image entirely free of form. He notes Venerable Yìnshùn's own summary of the same distinction in simpler terms — wisdom carries a note of decisiveness, the capacity to judge and settle a matter outright, while seeing carries a note of ongoing investigation, still searching and weighing — and stresses, as with insight's own five earlier names, that wisdom and seeing are ultimately two names for one and the same faculty of discernment, distinguished only by which of its many functions is being highlighted in a given context.

Master Cháng Bǎi treats this as the treatise turning, at last, to dismantle everything the previous several sections have so carefully built up — because knowing the Dharma's five aspects and the meaning's four nested frameworks were never meant to become new objects of clinging in their own right. The mechanism works in two steps at once, illustrated through the simplest case, a single name: first, nothing whatsoever is found when one searches for the name and its supposed own-nature, since a name is purely imagined, projected by the conceptualizing mind onto experience and never actually residing in the thing it labels — this alone would risk collapsing into nihilism if left there, denying that anything real underlies the name at all. So a second, simultaneous step is needed: one also stops observing what that name was imagined onto in the first place — not by declaring that underlying dependently-arisen reality to be simply nonexistent either, but by no longer fixing it as a separate object to be grasped, superimposed upon, or denied. Held together, these two steps release both of the classic extremes this whole treatise has traced since its opening sections: neither superimposing a fixed reality onto what is merely conventionally designated, nor denying the dependently-arisen and perfected reality that designation was always resting upon — precisely the double release that discloses the perfected nature and carries a bodhisattva into genuine, non-conceptual realization of mind-only truth. Master Cháng Bǎi then notes the passage's own instruction that this identical two-step release applies, without exception, to every single category the treatise has spent so long establishing — not only names, but phrases, letters, and every one of the meanings gathered under the ten-fold, five-fold, four-fold, and three-fold frameworks, all the way through to the very last of them, knowing the realm itself. Nothing a bodhisattva has learned to know, in other words, is meant to survive as a fixed possession of the mind; each act of knowing is meant to dissolve, in the end, into the same suchness it was always pointing toward.

Master Cháng Bǎi reads the Buddha's first answer as closing off an infinite regress before it can start: realizing suchness is what subdues every mark of the Dharma and its meaning, and nothing further is needed, or even possible, to subdue that realization in turn, since suchness is empty of any mark to begin with — there is simply nothing left over for a further act of removal to work on. Maitreya's question then shifts from what is realized to who realizes it, reaching for three similes of an unfit instrument: water too murky to show a reflection, a mirror too soiled to show a face, a pool too wind-stirred to hold a still image — each standing for a mind not yet cultivated enough to observe suchness as it truly is, since only the opposite of each, clear water, a polished mirror, a still pool, can actually do so. The Buddha's answer names three such minds, exactly the three kinds of wisdom the treatise has already distinguished at length several sections earlier: the observing mind produced by hearing, still confined to the literal text; the observing mind produced by reflection, able to judge a teaching's underlying intent though not yet meditatively grounded; and the observing mind produced by cultivation, which alone brings the object vividly present through actual absorption and is alone capable of the clear, undistorted observation the similes describe. Master Cháng Bǎi notes the deliberate choice of suchness here — the suchness of discernment, the mind-only teaching demonstrated earlier through the mirror simile in this very chapter — since the question at stake is not some external object at all, but the mind's own capacity to see clearly, and it is precisely mind-only's own suchness, disclosing that seer and seen were never really two things apart, that explains why cultivating the mind itself is the one thing capable of clarifying what it observes. With this, the treatise's account of removing every mark through the attention of suchness is complete, and the discussion now turns to naming, one by one, exactly which subtle marks remain to be removed, and by which of seventeen kinds of emptiness each is overcome.

Master Cháng Bǎi walks through three more pairs of subtle mark and antidote. Learning what grasps — the senses, mind, and mental factors already introduced — breeds a fond, possessive attachment to the very body these faculties inhabit, and a conceit that compares and elevates oneself above others on the strength of that same body and mind; inner emptiness dissolves the first by finding no lasting, independent self anywhere within the five faculties, mind, or mental factors, while the emptiness of what cannot be apprehended dissolves the second, since nothing is ever truly gained or possessed that could serve as grounds for pride in the first place. Learning what is grasped — the six outer objects — breeds an attachment to possessions accumulated through them, dissolved by outer emptiness, which finds no self and no fixed thing in any external object at all; Master Cháng Bǎi cites the vivid image of a hungry ghost recalling a past life spent hoarding wealth by fair means and foul, only to watch someone else now enjoy that same wealth while he alone suffers poverty — a warning that what is grasped outside the self was never securely held to begin with. And learning what is enjoyed — the requisites of daily life, together with the mutual attentions of male and female — breeds two further marks: an inward sense of ease taken in the body's own comfort, and an outward sense of refinement taken in the fineness of what is enjoyed; inner-and-outer emptiness, finding no fixed self or other behind the very distinction of male and female — Master Cháng Bǎi cites a verse that "the natures and marks of male and female were always empty; false grasping, conditioned by circumstance, gives rise to these two appearances" — dissolves the first, while emptiness of essential nature, finding that nothing possesses any fixed nature of its own to be refined or coarse in the first place, dissolves the second.

Master Cháng Bǎi explains that even the sheer, awe-inspiring vastness of the physical world-system surveyed earlier in this chapter — countless world-systems stretching through all ten directions — can itself become an object of subtle attachment, mistaken for something grand and therefore real; great emptiness removes this by showing that this very vastness arises and passes away through cycles of formation, endurance, decay, and final emptiness, sustained only by the collective karma of the beings who inhabit it, with no fixed, independent greatness of its own to be found. Learning the absence of form — the formless realm's four attainments, boundless space, boundless consciousness, nothing whatsoever, and neither perception nor non-perception — breeds a different danger: mistaking their profound inward stillness for genuine liberation itself, a mark of "inward quiescence and freedom" that a practitioner, or an outside ascetic reaching the same attainment, can easily take for nirvāṇa. The emptiness of the conditioned removes this by insisting that these states, however deep, remain thoroughly conditioned — affliction's seeds are merely suppressed within them, never actually uprooted, so that once the conditioned state runs its course, a being inevitably falls back into the round of rebirth exactly as before, no closer to true liberation than when the attainment first began.

Master Cháng Bǎi treats this eighth mark as the subtlest so far, since what must now be released is not ordinary craving but the very insights the whole treatise has spent so long establishing, if any one of them hardens into a fixed possession of the mind. Ultimate emptiness removes clinging to "the selflessness of persons" itself: since a person was never findable to begin with, there is nothing left over, once that search comes up empty, to hold onto as a further positive achievement called "no-self" — the insight and its object dissolve together. Emptiness of any nature removes clinging to "the selflessness of dharmas" in the very same way: not even the subtlest trace of a fixed nature can be found in any dharma, so if "dharma-selflessness" is grasped as some further characteristic standing on its own, this too must be released. Emptiness of the very nature of no-nature removes clinging to the mind-only teaching itself: mind-only denies that external objects possess any nature of their own apart from consciousness, but this was never meant to install consciousness in their place as some newly fixed, independently real thing to cling to instead — the "own-nature" spoken of here is precisely the absence of any external nature, and even this absence must not be turned into a possession. And emptiness of the ultimate removes clinging to the very idea of "the ultimate" as a graspable characteristic: true ultimate reality carries no mark whatsoever, so the moment one thinks "the ultimate has such-and-such a feature," that thought has already fallen short of the ultimate it was trying to describe — only by seeing that even the ultimate is empty of any mark to seize does the ultimate finally stand fully disclosed. Master Cháng Bǎi notes that, counted individually, the emptinesses named across all ten marks come to seventeen in total — a count distinct from, and more finely divided than, the eighteen emptinesses more familiar from the Prajñāpāramitā tradition, though covering substantially the same ground.

Master Cháng Bǎi treats the ninth mark as nirvāṇa's own subtlest temptation: having learned that cessation is the unconditioned, free of arising, abiding, changing, and ceasing, a practitioner can quietly turn "the unconditioned" and "changelessness" themselves into fixed, positive characteristics to be grasped — as though nirvāṇa were some permanent thing standing apart from the conditioned world, waiting to be possessed. The emptiness of the unconditioned dissolves the first by noting that, since the conditioned itself was never ultimately findable, there is no fixed "unconditioned" left over to stand apart from it as a further graspable object; the emptiness of changelessness dissolves the second by insisting that true reality lies beyond every trace of conceptual elaboration, so that even calling it "unchanging" risks smuggling in a subtle characteristic where none should remain. And the tenth mark closes the entire sequence by turning the whole method back on itself: having used nine distinct emptinesses as antidotes to nine distinct marks, a subtle new attachment can still arise — pride in having attained or understood emptiness, treating emptiness itself as a possession, an accomplishment, one more thing to hold onto. The emptiness of emptiness removes even this, emptying out the very medicine used to treat the disease, so that in the end neither the nine marks nor the nine antidotes applied against them remain as anything fixed to grasp. With this tenth and final emptiness, Master Cháng Bǎi notes, the treatise's account of removing every subtle remaining mark through the seventeen emptinesses is complete, and nothing whatsoever is left standing as an object still to be released.

Master Cháng Bǎi reads this exchange as guarding against a subtle trap the whole seventeen-emptiness practice could otherwise fall into: even the very act of contemplating emptiness still generates its own meditative image, a mental representation of "emptiness" standing in the mind where the ten marks once stood — and if left unexamined, this image could itself quietly harden into a new object of attachment, simply replacing one fixed mental furniture with another. What is actually removed, then, is precisely this residual image, not merely the original ten marks it was brought in to counter. Once that image itself is released, the mind is freed from what the passage calls the bondage of defilement — the underlying seeds that kept generating attachment to begin with, rather than merely their outward expression — and, in the very same breath, even this liberation is said to be removed as well, so that no fixed notion survives at any level: not the original marks, not the emptiness used against them, not the image emptiness itself produced, and not even the idea "I have now been liberated from bondage." Master Cháng Bǎi calls this the treatise's most thorough demonstration yet of what genuine non-attachment actually requires — a release so complete that liberation itself leaves no further trace to cling to.

Master Cháng Bǎi treats this clarification as essential to reading the whole seventeen-emptiness teaching correctly: pairing a specific emptiness with a specific mark — the emptiness of all dharmas with attachment to the written word, the emptiness of essential nature with attachment to refinement, and so on through all seventeen — names only the most direct and fitting antidote for each case, not an exclusive one. Any single emptiness, genuinely realized in full, dissolves attachment wherever it appears, since all seventeen are, at bottom, different facets of the identical single realization rather than seventeen separate remedies each limited to its own narrow complaint. He illustrates the logic with the standard chain of dependent origination: ignorance is the root condition running through the entire twelve-link sequence, present in some sense all the way from volitional formations down to aging and death, and yet the formula names only "ignorance conditions volitional formations" as its paradigm case — not because ignorance causes formations alone, but because formations stand in the most immediate, proximate causal relation to it, making that pairing the clearest way to teach the principle. In precisely the same way, Master Cháng Bǎi says, naming one emptiness as the antidote to one mark simply highlights the most direct and instructive pairing, without denying that a bodhisattva who has genuinely mastered even a single one of the seventeen has, in truth, already gained what is needed to dissolve every mark the whole set was ever meant to address.

Master Cháng Bǎi reads Maitreya's final question here as seeking the one formula that ties all seventeen emptinesses back into a single, unified statement — and finds the Buddha's answer reaching all the way back to the three-natures teaching this whole chapter first established: the total characteristic of emptiness is simply the imagined characteristic's utter and permanent absence from both the dependent and the perfected characteristics, defiled or pure alike, together with the further point that even within this very absence nothing whatsoever is apprehended, so that the absence itself is never turned into some new thing to grasp. The Buddha's uncharacteristically emphatic praise, and his warning that a bodhisattva who corrupts this understanding of emptiness thereby corrupts the entire Mahāyāna, Master Cháng Bǎi takes with full seriousness: the whole edifice of bodhisattva practice rests on getting this exactly right, and the two ways of getting it wrong — superimposing a fixed reality onto what is merely conventionally designated, or denying the dependently arisen and perfected reality that designation was always resting upon — are named in an earlier fascicle as the two failures that corrupt the Mahāyāna specifically, exactly the same wrongly-grasped emptiness this treatise has already dramatized once before, in the story of the teacher and students who mistook "all dharmas lack nature" for outright nihilism. With this total characteristic of emptiness stated, the treatise's sixteenth topic — removing every subtle mark through the seventeen emptinesses — comes to its close.

Master Cháng Bǎi reads the seventeenth topic's answer as sweeping and complete: every named absorption in the entire canon — the Śūraṅgama-samādhi and countless others taught to śrāvakas, bodhisattvas, and buddhas alike — is, without remainder, an instance of calm-abiding and insight; there is no third practice standing outside these two that any samādhi could belong to instead. The eighteenth topic then turns from what these two practices include to what produces them in the first place, naming two causes working together: pure moral discipline as the foundation, since a mind free of regret over broken precepts settles naturally, undisturbed by the agitation that guilt and wrongdoing otherwise stir up, and a practitioner who guards the senses through discipline finds affliction already diminished before meditation even begins; and the correct view produced by pure hearing and reflection as the second cause, the conceptual groundwork — gained by drawing near a good teacher, listening to the teaching, and reflecting on it — that meditation then translates into actual realization. Master Cháng Bǎi cites a canonical exchange making the same two-part sequence explicit: the Buddha telling a disciple to first purify discipline and straighten out view, and only then take up the four foundations of mindfulness — since without both a settled conduct and a rightly oriented understanding already in place, sustained meditative practice has nothing stable to build upon.

Master Cháng Bǎi identifies the well-purified mind as calm-abiding's own fruit and the well-purified wisdom as insight's own fruit, and glosses both through the accomplishment of an adept who has completed the path: for a śrāvaka reaching arhatship, the well-purified mind is the permanent extinguishing of every seed of craving, called liberation of mind, and the well-purified wisdom is the permanent departure from ignorance, called liberation through wisdom; for one following the Mahāyāna all the way to buddhahood, the same two fruits ripen into the full complement of mental factors accompanying non-conceptual wisdom and its subsequent wisdom together, expressed as the purified wisdom, the wisdom of the path in all its varieties, and omniscience itself. He then broadens the claim to its fullest scope: every wholesome quality that exists at all, whether mundane or supramundane, whether belonging to a śrāvaka's more limited attainment or to a buddha's complete and unsurpassed one, traces back to nothing other than calm-abiding and insight — even a buddha's own wisdom, though itself entirely uncontaminated, is still said to engage the mundane world through its subsequent wisdom, and so the treatise does not hesitate to call even a buddha's own accomplishments, in this specific sense, mundane as well as supramundane. With this, the treatise's account of the fruit of calm-abiding and insight is complete, closing the eighteenth of Maitreya's questions on the cause and fruit of this whole practice.

Master Cháng Bǎi surveys several ways commentators have unpacked the bondage of characteristics, all converging on a single point: it is the outward, active grasping at appearances as though they were substantially real. One reading locates it in every mental image a contaminated mind produces, which keeps the mind's own seeing-function from recognizing that what it perceives is illusion-like rather than truly existent; another locates it specifically in the seventh consciousness, whose four constant afflictions — self-delusion, self-view, self-conceit, and self-love — distort how the other six consciousnesses relate to whatever they perceive, so that pleasing objects provoke craving and displeasing ones provoke aversion, the mind never quite free in either case; a third finds it even in virtuous action, as when giving is still shadowed by a lingering awareness of giver, gift, and recipient as three separate, substantial things, which keeps the practice from truly reaching the far shore it aims at. Coarseness, by contrast, names not the active grasping itself but what lies beneath it and makes it possible: the dormant seeds of the afflictive and cognitive obstructions, still present in the mind's depths even when no affliction is currently active, and the general unfitness they impose on body and mind alike, leaving both incapable of sustained, wholesome effort until those seeds are actually uprooted. Master Cháng Bǎi stresses the practical stakes of the distinction: a practitioner whose afflictions are momentarily quiet can easily mistake this calm for freedom, not realizing the seeds remain fully intact, ready to spring back into activity the instant a suitable object appears — like a thief merely lying low rather than truly driven off. Only calm-abiding and insight working together, he says, can accomplish both tasks at once: calm-abiding stilling the mind so that insight can see through the grasping at appearances, and insight cutting deep enough to reach the dormant seeds themselves — freeing a practitioner, in every posture of daily life, from both the surface bondage and the hidden bondage underneath it.

Master Cháng Bǎi identifies these as the five bonds an earlier fascicle names as obstacles to the supramundane path. Longing attachment to the body and to possessions — constant preoccupation with the body's comfort and constant scheming after wealth — keeps beginningless craving stirred up and constantly pulling the mind outward, exactly the restlessness calm-abiding's settling cannot coexist with. Failing to gain mastery over the sacred teachings — never properly listening, receiving, becoming versed in, reflecting on, and penetrating the twelvefold scripture — leaves insight with no material to discern in the first place, since its fourfold operation of discernment has nothing to work on without a properly understood teaching underneath it. Delighting in mixed company obstructs both at once: Master Cháng Bǎi cites an earlier fascicle's warning about a monk who, ordained on a sudden, still-fragile faith, goes on to live casually among practicing and unpracticing monastics and laypeople alike, trading news and reminiscing about old friends and family until longing for the life he left behind creeps back in, quietly draining away the four joys of renunciation, seclusion, tranquility, and awakening. Being satisfied with the least attainment obstructs both in a different way: a practitioner who tastes some small measure of Dharma-flavor and stops there, content, never presses on toward what lies further ahead. The Buddha's own gloss draws the line precisely: delighting in mixed company means a practitioner can never even begin sustained practice, since there is never enough undisturbed time or settled mind to start; being satisfied with little means whatever practice is begun never reaches its consummation, stalling out exactly where ease first set in.

Master Cháng Bǎi walks through all five hindrances in turn. Restlessness is the mind's own agitated, leaping quality, stirred up by thoughts of family, homeland, or remembered pleasures — a turbulence directly opposed to the stillness calm-abiding requires. Remorse is regret over past deeds, whether wholesome or unwholesome, replaying again and again why one acted or spoke as one did — an unsettled churning that, like restlessness, prevents the mind from ever growing quiet, which is why the two are named together as obstacles to calm-abiding specifically. Dullness is the mind sinking below the clarity its object requires, the way a fish sinks beneath the water's surface and can no longer see what lies above it; drowsiness is dullness carried further still, where the object disappears from awareness altogether. Doubt is unresolved uncertainty about one's teacher, the teaching, the training, its guidance, or the very fruit one is meant to realize — a mind caught wavering between two possibilities, unable to commit to either. Because insight requires bright, decisive clarity to discern anything at all, dullness, drowsiness, and doubt are named together as obstacles to insight specifically. Craving and hatred, by contrast, obstruct both at once: craving pulls the mind outward chasing after pleasing forms, sounds, and the rest, denying it any settled rest while simultaneously clouding the clear judgment insight depends on; hatred, whether stirred by a real or imagined wrong from the past, present, or anticipated future, likewise agitates the mind out of stillness while blinding it to its own faults, since anger rarely leaves room for honest self-examination. Together, these five hindrances and the five bonds named just before them complete the treatise's account of what obstructs calm-abiding and insight.

Master Cháng Bǎi flags the apparent paradox here before resolving it: dullness and drowsiness were just named as obstacles to insight, not to calm-abiding, and yet calm-abiding's own completion is measured by their removal. He resolves it by pointing to what joined operation actually requires: once calm-abiding and insight are truly united, calm-abiding can no longer be a merely suppressed, dim stillness — it must carry insight's own vivid clarity within it, since the two no longer function as separate, alternating practices at that stage but as a single, indivisible activity of mind. A calm-abiding still shadowed by any residual dullness is therefore not yet complete calm-abiding at all, however still it may feel, because true stillness at this depth is inseparable from wakeful clarity. He cites the Yogācārabhūmi Commentary's own gloss on the logic: calm-abiding gives rise to insight, calm-abiding the cause and insight the effect, so naming the removal of the effect's own obstacle is simply another way of naming the cause's own full completion. He also recalls an earlier fascicle's account of what joined operation requires at minimum — the ninth and final stage of mental abiding, full absorption, as the basis from which insight-wisdom then arises effortlessly, "clean and bright, following calm-abiding's own settled, pliant quality" — and this, precisely, is what it means to say the path of calm-abiding has reached full and complete purity.

Master Cháng Bǎi reads this as the mirror image of calm-abiding's own completion just given: exactly as calm-abiding's purity is measured by insight's characteristic obstacles being removed, insight's purity is measured by calm-abiding's own obstacles, restlessness and remorse, being removed in turn. The logic runs the same direction: once truly joined, insight can no longer be a sharp but scattered discernment — it must itself rest on complete stillness, since a mind still agitated by restlessness or clouded by regret cannot sustain the settled clarity genuine insight requires. He cites the Yogācārabhūmi Commentary's parallel gloss — naming the removal of the cause's own obstacle to display the effect's full completion — and notes that a pure calm-abiding grounded in this way lets a practitioner's concentration become clean, bright, upright, and pliant enough to enter direct realization of the four noble truths, all the way to the final exhaustion of the contaminants. Master Cháng Bǎi adds a practical reassurance for readers troubled by an apparent inconsistency across different passages of the treatise — some pairing dullness with calm-abiding's obstacles and restlessness with insight's instead of the reverse — noting that either reading arrives at the same destination: joined operation, once truly reached, has necessarily left every one of the five hindrances behind together, so there is no need to be hemmed in by which specific pairing a given passage happens to use.

Master Cháng Bǎi treats distraction of intention as the danger facing a bodhisattva of indeterminate lineage in particular: quietly setting aside the great resolve to benefit all beings and drifting back toward a śrāvaka's or pratyekabuddha's narrower aim of personal liberation alone — he cites Śāriputra's own legendary lapse, who, after ten eons perfecting the stage of provisions, faltered on being asked to give up his very eyes and fell back from the bodhisattva path, and the Mahāprajñāpāramitā-śāstra's own image of how rare a bodhisattva's resolve is to carry through to fruition, like fish spawn or flowers on a certain tree — abundant at the start, vanishingly few that ever mature. He explains outward distraction of mind as the more familiar case of a mind let loose among the five sense pleasures — form, sound, smell, taste, and touch — where confused appearances give rise to misguided trains of thought (an earlier fascicle lists eight, from thoughts of desire and harm to thoughts of one's homeland, family, or mortality) and these in turn stir up the five hindrances, so that the mind, rather than being reined in, is simply allowed to stream outward toward its object without restraint. Inward distraction of mind, by contrast, arises even while the mind stays turned inward, proving that facing inward is no guarantee of stillness: dullness clouds the object's clarity the way a fish sinks below the water's surface out of sight; drowsiness removes the object from awareness altogether; sinking is a milder version of the same failure, where the object appears only faintly, lacking the bright, distinct clarity genuine absorption requires; and even delight taken in some meditative attainment already reached, or contamination by whatever secondary affliction happens to accompany that attainment, counts as inward distraction as well — since even a mind resting in genuine stillness can still be quietly pulled off course by satisfaction in its own accomplishment.

Master Cháng Bǎi surveys several readings of distraction of characteristics. Master Yǎnpéi takes "outer characteristics" as whatever was seen, heard, sensed, or cognized before samādhi was ever attained, and "the characteristics occurring within inner sustained concentration" as the image that same object casts inside samādhi itself — the inner image being the near object-condition, the outer thing-in-itself the distant one. Though distant, a practitioner in samādhi still finds himself picking it apart, discriminating and investigating it, and it is precisely this discursive handling that keeps the object from becoming vividly present and keeps the mind from settling — hence "distraction of characteristics." Elder Miàojìng's reading runs in parallel, distinguishing the same near and far object-conditions. A second family of readings, drawn from the *Madhyānta-vibhāga* and the *Abhidharmasamuccaya*, takes "outer characteristics" differently: a practitioner who has not actually attained samādhi outwardly feigns perfect stillness — faculties unmoved, uncomposed, apparently at peace — purely to convince others of his diligence, while inwardly the mind runs on in a private torrent no quieter than an ordinary chattering person's; sooner or later the pretense collapses and forces him into some further lie (a sudden ailment, a ruined spine) just to excuse no longer sitting. Both readings — inward grasping at an outer object, or outward pretense covering inward chaos — are named distraction of characteristics because both disturb the mind and obstruct calm-abiding and insight alike; a *Madhyānta-vibhāga* commentary adds a third nuance, that an intention toward a lower stage not yet decisively relinquished can itself, as a "characteristic," pull an already-attained samādhi back down. Distraction of coarseness is read more simply: even a practitioner who has genuinely entered dhyāna and tastes its joy, bliss, or equanimity is still tasting a coarse feeling, one that carries the dormant seeds of affliction, since attaining concentration is not the same as uprooting them. Feeling itself is neither self nor belonging to a self, but sentient beings habitually fuse feeling with self all the same, and out of that fusion arises the quiet conceit of "only I can attain this; others cannot." Master Cháng Bǎi closes with a summary of the whole fivefold scheme: distraction of intention keeps a bodhisattva from ever reaching unsurpassed bodhi; outward distraction of mind keeps him from attaining concentration at all; inward distraction and distraction of characteristics cause concentration already attained to regress; and distraction of coarseness keeps him from liberation — five distinct failure modes a bodhisattva must learn to relinquish in turn.

Master Cháng Bǎi walks through each ground by name and by the pair of "delusions" (愚) the *Yogācārabhūmi*'s Decisive-Discussion chapter (juan 78) assigns it. The first ground, Utmost Joy, is where a bodhisattva first realizes a portion of the twofold emptiness of self and dharmas after a full incalculable eon of preparation; its calm-abiding and insight overcome the delusion of clinging to person and dharma and the delusion of defilement belonging to the evil destinies, so that from this ground on a bodhisattva never again falls to hell, hungry-ghost, or animal rebirth — Master Cháng Bǎi notes this is called "entering the correct nature apart from birth," and cites the well-known verse that even a worldly being of sufficiently strong right view, through the power of vow, will not fall into the evil destinies though reborn a hundred thousand times. The second ground, Free from Defilement, perfects the precept-pāramitā by naturally avoiding even subtle inadvertent transgressions, overcoming the delusion of subtle transgression and the delusion regarding the varieties of karmic destiny. The third ground, Emitter of Light, whose samādhi never again regresses, overcomes desire-realm craving entirely — its bodhisattva is functionally equivalent to a non-returner in the śrāvaka path — together with the delusion obstructing the perfection of retained teachings. The fourth ground, Blazing with Wisdom, burns away remaining afflictions like a fire consuming firewood; its calm-abiding and insight sever the innate view of self, self-delusion, self-love, and self-conceit that the *Cheng Weishi Lun* locates in the sixth consciousness, overcoming both attachment to the flavor of concentration already attained and attachment to the Dharma one has learned by heart. The fifth ground, Utmost Difficulty to Conquer, is where root wisdom and subsequently attained wisdom — one non-discriminating and objectless, the other discriminating and engaged with names and characteristics — are at last held together, so that saṃsāra and nirvāṇa, conditioned arising and emptiness, no longer pull the bodhisattva toward one at the exclusion of the other; earlier grounds may still feel some pull to renounce saṃsāra for the sake of nirvāṇa, but from the fifth ground this exclusive orientation is overcome.

The sixth ground, Manifest Presence, takes the twelve links of dependent arising as its basis, bringing prajñā's non-discriminating wisdom directly before the mind by realizing that conditioned arising is itself emptied of substance; its calm-abiding and insight overcome the delusion of directly observing the flow of formations and the delusion of the frequent arising of characteristics — specifically the coarse marks of clinging to the defiled aspect of the four truths (suffering and origination as flow) and their pure aspect (cessation and path as return). The seventh ground, Far-Reaching, sits exactly at the boundary between effortful and effortless practice — the last ground where entry into signlessness still requires exertion — and its calm-abiding and insight overcome the delusion of the arising of subtle characteristics and the delusion of exclusively directing intention toward the signless, subtler counterparts of the sixth ground's grasping at arising and ceasing. The eighth ground, Immovable, is where effortless practice finally begins, no longer disturbed by affliction of any kind; its calm-abiding and insight overcome both the delusion of still exerting effort toward the signless and the delusion of not yet having free mastery over characteristics, so that signless wisdom now operates spontaneously and characteristics and buddha-lands can be manifested at will. The ninth ground, Excellent Wisdom, gains the four unobstructed forms of eloquence — the meaning, the teaching, the diction, and confident exposition — able to expound the Dharma to beings everywhere without hindrance in any language; its calm-abiding and insight overcome the delusion obstructing free mastery of dhāraṇī with respect to boundless teachings, words, and successively refined wisdom, and the delusion obstructing free eloquence itself. The tenth ground, Cloud of Dharma, takes its name because its wisdom, like a great cloud, holds within it every dhāraṇī- and samādhi-gate, covers over the vast expanse of beginningless subtle obstruction the way clouds cover the sky, and pours down the rain that perfects the Dharma-body; its calm-abiding and insight overcome the delusion of great supernormal powers and the delusion of penetrating subtle secrets, the last obstacle before the Dharma-body — though even here Master Cháng Bǎi notes some most subtle habitual traces of the two obstructions remain, to be finished only at buddhahood itself.

Master Cháng Bǎi closes the eleven-ground survey (ten bodhisattva grounds plus the Tathāgata ground) with what only buddhahood itself overcomes: the delusion of extremely subtle attachment to every knowable object, and the delusion of extremely subtle obstruction — the very last, most deeply hidden remainder of the two obstructions, which even a tenth-ground bodhisattva's otherwise-perfected Dharma-body has not yet shed. He cites the *Sub-commentary on the Saṃdhinirmocana-sūtra*'s threefold gloss on "extremely" and "utmost": extremely subtle is what is cut off only at the very limit of practice, utmost subtle is what is cut off only at its most excellent stage; nothing subtler remains to be cut, hence extreme; nothing remains to be surpassed, hence utmost. Citing the *Cheng Weishi Lun* and *Buddhabhūmi-śāstra-treatise*, he notes that innate afflictive obstruction and the innate portion of cognitive obstruction are deliberately left uncut through all ten grounds — held in reserve, as it were — and are severed all at once only when the vajra-like samādhi manifests immediately before buddhahood. Having permanently destroyed these last obstructions, a buddha ultimately realizes knowledge and vision that is unattached and unobstructed with respect to every dharma, and — his eighth consciousness now transformed into the stainless consciousness, both the object of cognition and its basis now purified — establishes the utmost pure Dharma-body, which the ten grounds' own Dharma-body, complete as it is, has still not equaled; Master Cháng Bǎi cites the *Sūtra on the Original Vows* account of the "equivalent-enlightenment" abode a tenth-ground bodhisattva must still occupy for thirteen thousand eons of continued calm-abiding and insight before entering the wondrous-enlightenment ground of a Tathāgata. He also glosses "the object accomplished through completed activity" as the fourth and last of the four kinds of object earlier taught in the Śrāvaka-bhūmi's account of all-pervading objects — the object with images subject to discrimination (insight), the object with images free of discrimination (calm-abiding), the object at the very limit of a matter (the joint exhaustive-nature and true-nature insight cultivated within calm-abiding), and the object accomplished through completed activity, attained only at the fruition of calm-abiding and insight operating as one — comparing the process across the ten grounds to a goldsmith's threefold refining of ore: first washing away impurities, then melting the metal bright and workable, then tempering it supple, a metaphor for the mind's own gradual refinement all the way to unsurpassed complete enlightenment, urging that even bodhisattvas of the highest grounds must never rest content with what has already been attained.

Having finished surveying what calm-abiding and insight overcome ground by ground, Maitreya now asks the culminating question of the whole chapter: how, exactly, does a bodhisattva relying on calm-abiding and insight actually reach unsurpassed bodhi? Master Cháng Bǎi frames the Buddha's answer as unfolding in three stages — the stage of application (the four roots of goodness: heat, summit, forbearance, and supreme worldly dharma), the stage of seeing, and the stage of cultivation — beginning here with application. He first offers a plain paraphrase and then, drawing on the *Sub-commentary*, the *Cheng Weishi Lun* juan 9, Master Yǎnpéi's vernacular commentary, and Elder Miàojìng's teaching, unpacks it in depth. Of the five stages of Mahāyāna practice — provisions, application, seeing, cultivation, and consummation — provisions and application are still stages of an ordinary being; a bodhisattva in the stage of provisions has generated the deep, firm bodhi-mind but not yet the resolve that opens onto ultimate reality, still dwells mostly outwardly with a scattered mind, and cannot yet penetrate the nature and characteristics of consciousness-only. After a full incalculable eon of accumulating these provisions, having attained contaminated calm-abiding and insight, one enters application — the stage of heat, summit, forbearance, and supreme worldly dharma referred to here. Recalling how an earlier fascicle defined calm-abiding (sustained attention on a single object without outward scattering, until bodily and mental pliancy arise) and insight (examining, most-thoroughly-examining, and thoroughly reflecting upon that same object's image within concentration, whether through confidence, delight, wisdom, seeing, or contemplation), Master Cháng Bǎi maps each clause of the root text onto the threefold progression of hearing-wisdom, thinking-wisdom, and cultivation-wisdom: "well established" corresponds to hearing-wisdom, having already mastered the sevenfold suchness in name and word during the provisions stage; "well considered" corresponds to thinking-wisdom, having further penetrated the intent behind the words — that the sevenfold suchness as verbally established is not [ultimately] existent, yet apart from words is not [simply] non-existent either, the secret meaning of emptiness-and-existence being non-dual; and "well ascertained... correctly reflecting within" corresponds to cultivation-wisdom itself, where a bodhisattva now in the fourth dhyāna — the most excellent concentration, free of the taints of craving, conceit, views, doubt, and ignorance, and able to enter, abide in, and emerge from it at will — takes up the sevenfold suchness image arising within that concentration and cultivates the four kinds of examination and the four kinds of true, real knowledge upon it. He also explains, citing *Cheng Weishi Lun* juan 9, why the sevenfold suchness specifically is the object here: an application-stage bodhisattva studies both the established truths (the four noble truths — corresponding to the established, deviant, purifying, and correctly-practiced suchnesses among the seven) and the unestablished truth (the emptiness of dharmas — corresponding to the suchness of flow, of characteristics, and of consciousness-only), the unestablished truth being what is actually to be directly realized while the established truths are studied as well so as to mature living beings and surpass the two lesser vehicles in the phase of subsequently attained wisdom — unlike śrāvakas, who study the established truths alone.

Master Cháng Bǎi cites the *Sub-commentary* juan 7's summary: an application-stage bodhisattva relying on the sevenfold suchness, through the power of superior concentration, practices the four kinds of examination at the stages of heat and summit — well ascertaining, well considering, retaining the awareness of consciousness while relinquishing the [grasped] characteristic — and the four kinds of true, real knowledge at forbearance and supreme worldly dharma, correctly reflecting within upon the well-established nature of suchness so as to relinquish the grasping consciousness itself. Correctly reflecting on true suchness in this way, the bodhisattva's mind can already relinquish every subtle characteristic occurring within meditative imagery — let alone the coarse characteristics of form, sound, smell, taste, touch, craving, aversion, delusion, and sexual difference that occur in an ordinary scattered state, already long abandoned. He then walks through the list the root text gives, matching each pair against the fourfold scheme of body, feeling, mind, and dharma per the *Sub-commentary*'s own gloss: the characteristic of what is grasped and appropriated corresponds to the body (still sensing a body even in deep reflection); the characteristic of experiencing corresponds to feeling (pleasant, unpleasant, or neutral sensations still arising); the characteristic of discerning corresponds to mind (the sense of "I know, I see" that any cognizing mind carries); and the characteristics of defilement and purity correspond to dharmas (whether some mental factor is recognized as afflictive or as a virtue like wisdom or non-craving). The inward characteristic is the earlier-named longing attachment to the body and self-conceit; the outward characteristic is longing attachment to possessions or to other beings; the inward-and-outward characteristic covers relational appearances such as attending to another with worldly resources, or whatever arises from the meeting of faculty and object. Even the resolve "I should practice to benefit all beings" is itself still a characteristic to be relinquished, since ultimately no being and no benefactor is substantially found; correct wisdom — whether root wisdom or subsequently attained wisdom — and the very characteristic of suchness that arises from reflecting on it are likewise still characteristics; so too are the characteristics of the four noble truths themselves — the pressing quality of suffering, the accumulating quality of origination, the stillness of cessation, the outward-bound quality of the path — the characteristic of the conditioned (marked by arising, abiding, and change) opposed to the unconditioned, of permanence (the unconditioned taken as unchanging) opposed to impermanence, and of the two aspects of suffering: suffering-with-change (the suffering of suffering and the suffering of change, tied to objects that themselves change) opposed to suffering-without-change (the pervasive suffering of formations, the ripened result that persists relatively unchanged through a single lifetime). The concluding pair, the different-characteristic and identical-characteristic of the conditioned, Master Cháng Bǎi glosses two ways: most directly, as the moment-to-moment dissimilar arising of conditioned dharmas (difference) against their similar, continuous succession (identity), per the *Sub-commentary*'s own definition; alternatively, following Elder Miàojìng's citation of Master Woncheuk, as the particular differences among form-dharmas and mind-dharmas (difference) against the universal truth that all conditioned dharmas alike are impermanent and suffering (identity) — a reading through each dharma's own specific versus shared characteristic. Every one of these, however doctrinally exalted, remains for the application-stage bodhisattva a subtle characteristic still to be let go.

Master Cháng Bǎi closes the list of subtle characteristics with the *Compendium of Determinations*' twofold gloss on "everything is everything": a partial everything and an everything-of-everything. To say all formations are impermanent invokes only the partial everything, since this holds only for conditioned dharmas and not for the unconditioned; to say all dharmas lack self invokes the everything-of-everything, spanning conditioned and unconditioned alike. He also offers a second, complementary reading in which the first "everything" names the exhaustive-nature of all dharmas (their complete taxonomy — the five aggregates, six inner sense-fields, six outer sense-fields, and so on) and the second names their true-nature (the sevenfold suchness, or equivalently the four noble truths, the sixteen aspects, impermanence, suffering, selflessness, the peace of nirvāṇa, emptiness, wishlessness, and signlessness) — so that reflecting on both the exhaustive-nature and the true-nature of all dharmas together gives rise to this characteristic of "everything." The selflessness of persons arises when the teaching's account of no self within the aggregates, and no self apart from the aggregates, is reflected upon; the selflessness of dharmas arises when the teaching's account of the selflessness even of dharmas as verbally established is reflected upon. Both, however exalted, are still characteristics currently arising in the mind, and the application-stage bodhisattva, through the very cultivation of the sevenfold suchness that produced them, is able to relinquish them as they occur — bringing the whole catalogue of subtle characteristics, and with it the entire stage of application, to its close. Master Cháng Bǎi notes the arc traced across this long passage: coarse characteristics of ordinary distraction were abandoned long ago; now even the mind's own subtlest doctrinal productions — suffering and its truths, permanence and impermanence, self and no-self — are released in turn, leaving nothing for the mind to stand on but suchness itself, exactly the condition from which the path of seeing can open.

Master Cháng Bǎi gathers up every obstacle the treatise has already named — the five bonds (longing for body and possessions, delighting in mixed company, lacking mastery of the teachings, being satisfied with little), the five hindrances (craving, hatred, dullness-and-drowsiness, restlessness-and-remorse, doubt), and the five kinds of scattered mind (of intention, outward, inward, of characteristics, of coarseness) — and notes that a bodhisattva abiding at heat, summit, forbearance, and supreme worldly dharma trains against all fifteen from time to time as they arise from the very subtle characteristics just relinquished. Once this training bears fruit, supreme worldly dharma's single instant of contaminated, fourfold true and real knowledge gives way, in the very next instant, to the effortless arising of uncontaminated non-discriminating wisdom, cutting off in one stroke every affliction to be abandoned by seeing and realizing the single, pervading suchness common to all — the true path of seeing. What follows the true path of seeing is the arising, with respect to the sevenfold suchness, of seven distinct wisdoms of personal realization: the subsequently attained path of seeing (相見道), whose purpose is to consolidate and make fluent what the true path of seeing has already realized. Citing *Cheng Weishi Lun* juan 9 and the Decisive-Discussion chapter (juan 55, 58), Master Cháng Bǎi notes the several traditional countings of this subsequently attained path — three mind-moments, nine mind-moments, or sixteen mind-moments — and offers a rough correspondence: the three-mind count maps onto reflection on the first three of the sevenfold suchness, while the nine-mind and sixteen-mind counts map onto the remaining four; all these countings, he stresses, are provisionally established only after and upon the true path of seeing, arising when a bodhisattva, having in the single moment of supreme worldly dharma left behind both grasped and grasping discrimination and every discursive elaboration to directly realize suchness with root wisdom, then rises from that root wisdom into subsequently attained wisdom to survey the unestablished and established truths once more, in a sequence provisionally described as three, nine, or sixteen mind-moments.

Master Cháng Bǎi glosses "correct nature" two ways — as nirvāṇa itself, the true nature of the Dharma, or as the uncontaminated noble path — and "apart from birth" as being severed, for a bodhisattva, from the seeds of both obstructions cut off by seeing (rather than merely from the three evil destinies, as for a śrāvaka stream-enterer). Having entered the ground, the bodhisattva penetrates deeply into the buddhas' own self-realized dharma-realm and shares in the very flavor of buddha-wisdom, so that the buddha-lineage continues unbroken through him — hence "born into the household of the Tathāgatas," a true child of the Buddha. Citing the *Bodhisattva-bhūmi* (juan 47), Master Cháng Bǎi surveys the excellent qualities newly enjoyed on this ground, chief among them freedom from all five fears. Freedom from fear of not surviving: an ordinary being's fear of destitution comes from clinging to a fixed, controllable "self" that must be provisioned against an uncertain future, but a first-ground bodhisattva, having realized the wisdom of the twofold selflessness, no longer generates even the discriminated notion of self, let alone attachment to his own person or possessions, and so can give away his very last bowl of rice though it cost him his life, where an ordinary person always holds something back against disaster. Freedom from fear of ill repute: having nothing to gain for himself, a first-ground bodhisattva acts wholly from the wish to benefit and give ease to beings, and will act even at the cost of his own reputation — resisting a tyrant to save the people, for instance — without hesitation. Freedom from fear of death: having already cut off the view of self, he generates no grief or dread at the prospect of losing or having destroyed a "self" that was never truly there. Freedom from fear of the evil destinies: his precepts pure and the afflictive and cognitive obstructions leading to the evil destinies already severed, he takes rebirth by the power of vow rather than by the pull of karma, certain to meet buddhas and bodhisattvas in every future life. Freedom from fear of speaking before an assembly: knowing no one else shares his heightened resolve to benefit and give ease to all beings at every moment, he teaches before any gathering, however exalted, without a trace of timidity. Beyond these five, Master Cháng Bǎi notes, the ground also brings freedom from alarm at hearing the profound Dharma, from arrogance, from anger at others' wrongs against him, and from craving for worldly wealth — an ardor for both mundane and supramundane virtue undimmed by any worldly notion — with still further excellent qualities detailed at length in the *Avataṃsaka-sūtra* and other Mahāyāna scriptures.

Master Cháng Bǎi ties this passage back to the four kinds of all-pervading object first taught in the Śrāvaka-bhūmi and already invoked at the close of the treating-obstructions door: the object with images subject to discrimination (insight), the object with images free of discrimination (calm-abiding), the object at the very limit of a matter, and the object accomplished through completed activity. A bodhisattva in the stages of provisions and application, continuously cultivating calm-abiding and insight though still with contamination present, had already attained the first two; now, having reached the path of seeing and the first ground, he further realizes the third — the object at the very limit of a matter, meaning the exhaustive comprehension of both a thing's exhaustive-nature (its complete taxonomic extent, as the five aggregates or the twelve sense-fields) and its true-nature (its suchness). Citing the Śrāvaka-bhūmi's own definition (juan 26) via the *Sub-commentary*, he notes this is precisely what "knowing the Dharma and knowing its meaning" earlier in this very fascicle described in such exhaustive detail — the tenfold, fivefold, fourfold, and threefold frameworks of knowing meaning are themselves nothing other than this third object now actually realized, no longer merely studied. A first-ground bodhisattva can, for the first time, genuinely know the specific and shared characteristics of every dharma as they truly are — a capacity that will only be practiced and deepened, ground after ground, until the fourth and final object, accomplished through completed activity, is reached only at buddhahood itself.

From the second ground onward, a bodhisattva in the path of cultivation continues training the same three objects already attained — with discriminated images, free of discriminated images, and at the very limit of a matter — so that their fineness and clarity deepen ground by ground. Master Cháng Bǎi glosses the carpenter's image directly: a builder drives a thick wedge from a joint by tapping in a thinner, sharper one behind it, a technique few readers will have seen firsthand but every carpenter knows. A bodhisattva does the same with ever subtler, ever more skillful wisdom, progressively driving out the coarser characteristic still lodged in the mind's meditative imagery with a finer one, so that every image tinged with defilement is at last thoroughly expelled; and because the characteristic itself is removed, the coarseness underlying it — the dormant seeds of the two obstructions that made the characteristic possible in the first place — is removed along with it, since what is not grasped as an object can no longer function as a condition for its own seeds to ripen. Master Cháng Bǎi offers the four dhyānas as an illustration of the relative scale involved: the first dhyāna is coarse relative to the second, the second coarse relative to the third, and so on; in exactly the same way, the first ground is coarse relative to the second, the second coarse relative to the third, each successive ground finer than the one before, until every characteristic that could still stir up defilement is exhausted. The underlying principle he draws out plainly: all characteristics are illusory, and wherever the mind still grasps at a characteristic, affliction can still arise — so calm-abiding and insight must continue, unbroken, binding both the fetter of characteristics and the fetter of coarseness together until neither remains to be untied.

Master Cháng Bǎi brings the entire door of realizing bodhi to its close here — the culmination of everything the chapter has taught about calm-abiding and insight, and, in a real sense, of the whole of Buddhist practice as this treatise presents it. From the first ground onward a bodhisattva must permanently sever both the currently arising characteristic and the dormant coarseness beneath it — the current defiled activity of the grasping mind together with its seeds — ground after ground, as though a goldsmith were refining ore through three successive stages: first washing away impurity, then melting the metal bright and workable, then tempering it fully supple. This threefold refining continues without pause all the way up to buddhahood; only there does the object itself become fully purified together with its basis, the ālaya or maturation consciousness transformed at last into the stainless consciousness, and only then is the fourth and final object — accomplished through completed activity — actually attained. Citing the Śrāvaka-bhūmi's own definition of this completed-activity object (juan 26), Master Cháng Bǎi explains that it names the state in which every attention directed toward meditative images, cultivated and practiced again and again across three full incalculable eons, at last reaches full perfection; this perfection itself effects the transformation of basis, extinguishing every last coarseness, so that the dependent nature no longer clings to the imagined nature at all, the great mirror-wisdom is fully realized, and mundane and supramundane function together in perfect equality — described in the scriptures as "the nāga ever abiding in samādhi," since a buddha's non-discriminating wisdom is present at every moment without exception, never once needing to rise from or re-enter concentration as an ordinary meditator must. The Buddha's own closing summary is deliberately spare: a bodhisattva who correctly cultivates the four objects — with discriminated images, free of discriminated images, at the limit of a matter, and accomplished through completed activity — from the very first arousal of the bodhi-mind all the way to the very threshold of buddhahood, realizes unsurpassed, perfect, complete enlightenment precisely and only through this unbroken inward practice of calm-abiding and insight. Master Cháng Bǎi notes explicitly that this closes the treatise's twenty-fourth of Maitreya's twenty-six questions, **the door of realizing bodhi** — the doctrinal heart of the entire chapter on distinguishing yogic practice, since every prior door, from the four objects of meditation through the seventeen emptinesses to the eleven grounds' obstructions, has been building toward exactly this account of how calm-abiding and insight, practiced together without interruption, actually carry a bodhisattva the whole distance from an ordinary being's first resolve to the unsurpassed enlightenment of a Buddha.

Master Cháng Bǎi opens the treatise's twenty-fifth door, on inducing majestic power, by naming what Maitreya is really asking after: the six supernormal powers, the power of the six perfections, the power of qualities co-arisen with realization, and the powers shared and unshared with śrāvakas and pratyekabuddhas — all of which, the Buddha answers, flow from skillfully knowing six things about mind itself, since the three realms are mind-only and the ten thousand dharmas are consciousness-only; without understanding mind, majestic power could never be exercised freely. The first of the six, knowing mind's arising, unpacks into sixteen kinds. The first is the ādāna-consciousness, better known as the eighth or ālaya-consciousness, whose three functions — appropriating the physical sense-faculties, holding the seeds, and grasping at rebirth-continuity — give it its name; "imperceptible" carries two senses, either that ordinary beings cannot discern the fine differences between what they themselves have transformed and what others have, or that this consciousness, being unobscured and indeterminate in nature, has an activity too subtle to be directly known, as Vasubandhu's *Triṃśikā* puts it: "its appropriating, its locus, and its cognizing cannot be known." "Firmly abiding" describes the vessel-world it manifests — mountains, rivers, the earth — which, though also subject to formation, abiding, decay, and emptiness, unfolds over a full great eon and so appears, from an ordinary being's vantage, changelessly stable; only a bodhisattva of the first ground or above can truly penetrate the ādāna-consciousness's own cognizing and cognized activity. The second, the consciousness with manifold aspects, is the sixth mental consciousness, on which every one of the first five consciousnesses depends for its own discrimination; Master Cháng Bǎi distinguishes an ordinary being's version — grasping all six kinds of sense-object and the feelings arising from their contact in a single instant — from a first-ground-or-above bodhisattva's, whose subsequently attained wisdom can, within the span of a single thought (roughly 0.013 seconds), an instant (about 1.6 seconds), or a moment (about a minute and a half), enter numerous samādhis, behold countless buddha-lands, and see numerous Tathāgatas face to face — a power entirely beyond ordinary reach. The third through seventh kinds all describe the ālaya-consciousness itself as it is respectively bound to the desire, form, and formless realms, taking its name each time from the scale of what it grasps: small (the desire realm's own coarse, cramped body and world), great (the form realm's vastly more spacious retribution), immeasurable (the boundless space or boundless consciousness that the two lower formless spheres take as their seed-bearing object), subtle (the sphere of nothing whatsoever, whose seeds arise from the conviction that nothing beyond consciousness itself can be found), and the outermost limit (the sphere of neither perception nor non-perception, the very summit of the three realms). Citing the *Mahāvibhāṣā* (juan 52), Master Cháng Bǎi notes eight traditional ways of explaining what "bound" (繫) itself means — bondage, affliction, self-and-what-is-mine grasping, craving and views, delight and desire, birth-and-death, defilement, and affliction again — all converging on the same point, that the Mahāyāna reading takes these three realm-bound consciousnesses as naming the ālaya-consciousness specifically, since (unlike the sixth consciousness, which shifts moment to moment across the three moral natures) it remains fixed to a single realm for an entire lifetime as genuine ripened retribution. The eighth, the signless consciousness, covers both the supramundane consciousness — root wisdom free of every contaminated elaboration — and the consciousness present during cessation-attainment, when the six active consciousnesses and the self-view-associated seventh have stopped functioning but an uncontaminated eighth consciousness remains. The ninth through thirteenth track feeling: the unrelievedly painful consciousness of hell-beings, the mixed pleasant-painful-neutral consciousness of desire-realm beings, the joy-accompanied consciousness of the first two dhyānas, the bliss-accompanied consciousness of the third, and the equanimity-accompanied consciousness from the fourth dhyāna up through the formless spheres. The fourteenth through sixteenth track moral quality: consciousness associated with the root and secondary afflictions, consciousness associated with the eleven wholesome mental factors beginning with faith, and consciousness associated with neither — the ordinarily indeterminate character of most of the six consciousnesses and of the eighth consciousness itself. Master Cháng Bǎi closes by stressing that only a bodhisattva who has mastered this entire sixteenfold taxonomy of how mind arises can go on to exercise a bodhisattva's vast majestic power with any real freedom.

Master Cháng Bǎi glosses "discerning suchness" — elsewhere rendered consciousness-only suchness, or the suchness of cognition — as truly knowing that every dharma is nothing but what consciousness manifests, citing the *Mahāyānasaṃgraha-bhāṣya*'s formula that on the path of expedient means all dharmas take consciousness as their characteristic, while on the path of seeing they take suchness as their very substance: an application-stage bodhisattva penetrates only the consciousness-only characteristic, while a bodhisattva who has entered the path of seeing actually realizes the consciousness-only nature itself. Abiding in this supreme, uncontaminated concentrated mind and penetrating one-pointedness of mind in just this way is what "skillfully knowing the abiding of mind" means. Skillfully knowing mind's emergence, by contrast, concerns the two bonds already treated at length earlier in this fascicle — the bond of characteristics (the image-aspect of the eight consciousnesses, or specifically the seventh, manas) and the bond of coarseness (the dormant seeds of the two obstructions) — and names a bodhisattva's ability to discern for himself whether his mind has actually emerged from these bonds, diligently cultivating calm-abiding and insight so that it does. Master Cháng Bǎi treats these two — abiding in suchness, emerging from bondage — as naturally following mind's arising: having rightly known how the sixteen kinds of mind arise, a bodhisattva must next know where mind can rest undistorted, and how it is actually freed from what binds it.

Master Cháng Bǎi treats increase and decrease as a matched pair, one tracking virtue's growth, the other affliction's shrinking. For increase, he offers the *Sub-commentary*'s distinction between "increase" as an already-existing seed's activity growing more forceful in the moment, and "accumulation" as the further planting of new uncontaminated habituated seeds through that very activity — so that as the noble path counteracting the two bonds grows more vigorous in its present functioning, the mind's own original seeds increase, and as it plants ever more new seeds through repeated practice, the mind's stock of seeds accumulates; a bodhisattva who truly knows both movements at once knows mind's increase. He notes an alternate gloss offering a shorthand version of the same distinction — activity intensifying is "increase," seeds being newly deposited is "accumulation" — and a third, still simpler reading, that initial growth is "increase" and repeated recurrence is "accumulation," all converging on the same underlying point. Decrease mirrors this exactly but for what is being counteracted: as the counteracting noble path strengthens, the bond of characteristics and the bond of coarseness that the path opposes correspondingly weaken in their present activity and diminish in their seeds, and a bodhisattva who truly knows this decline as it happens — not merely believing it in the abstract, but tracking with real precision exactly how far his own practice has progressed and exactly which portion of affliction has actually receded — knows mind's decrease. Master Cháng Bǎi stresses the practical value of this pairing: only a bodhisattva capable of this kind of exact self-assessment, neither overestimating his progress nor remaining ignorant of it, can go on to exercise a bodhisattva's vast and majestic powers with genuine, well-founded confidence.

Master Cháng Bǎi turns to the sixth and final of the six bases, skillfully knowing the means of application: truly knowing how to cultivate, or when instead to set aside, the eight liberations, the eight bases of mastery, and the ten bases of totality — a graduated sequence in which the bases of mastery build on the liberations, and the bases of totality build on the bases of mastery, the whole scheme, per the Samāhita-bhūmi (juan 12), undertaken to purify and remove afflictions still tied to desire-realm forms and to open the way to the most excellent supernormal accomplishments. The eight liberations: (1) contemplating external forms while still perceiving form inwardly — a practitioner who has left desire-realm craving but not yet form-realm craving deliberately reflects on desire-realm bodies and belongings under an imagined luminosity, weighing their better and worse qualities, without yet cultivating the contemplation of impurity that would sever craving outright; (2) contemplating forms while no longer perceiving form inwardly — the same reflection carried out by one who has attained a formless absorption but is not currently manifesting it, working instead from a form-realm basis; (3) the liberation of the pure, resting mainly on the fourth dhyāna, in which pure and impure forms are seen as mutually dependent and mutually interpenetrating — impurity concealed beneath a thin skin of apparent purity, as the treatise elsewhere puts it — until both dissolve into a single undifferentiated purity from which every hue, blue, yellow, red, and white, can be freely manifested, this liberation earning its name from having overcome both the affliction born of grasping purity-versus-impurity and the specific obstruction to transformative power that such grasping creates; (4) through (7), the four formless liberations, in which a practitioner successively frees himself from attachment to the boundless space, boundless consciousness, and nothingness already mastered in samādhi, and finally, having reached the very summit of existence, forms no further resolve beyond thorough weariness with the sphere of nothing whatsoever; and (8), the liberation of the cessation of perception and feeling, attained by a noble one of at least the third fruit who, pressing beyond even the most subtle single thought remaining in the sphere of neither perception nor non-perception and finding nothing further to grasp, brings the feeling and perception of the first six consciousnesses, together with the self-view-associated seventh, to a temporary halt altogether. Master Cháng Bǎi notes this eightfold sequence is the necessary foundation for the eight bases of mastery and ten bases of totality that follow, and that a bodhisattva's mastery of when to cultivate each and when instead to relinquish it is itself already a considerable exercise of skillful means.

Before this closing summary, Master Cháng Bǎi finishes unpacking "skillfully knowing the means of application" with the eight bases of mastery and the ten bases of totality that build upon the eight liberations just treated. The eight bases of mastery: the first and second, still perceiving form inwardly, contemplate a small and then a large quantity of external form — bodily belongings, then the whole of the sentient and insentient worlds — gaining first mastery-knowledge (through calm-abiding) that the object can be made to vanish from view, then mastery-vision (through insight) that it can be freely subdued; the third and fourth repeat this without any inward perception of form remaining; and the fifth through eighth, resting on the fourth dhyāna, contemplate all form as uniformly blue, then yellow, then red, then white — likened respectively to the utpala flower or blue-dyed cloth of Vārāṇasī, the karṇikāra flower, the bandhūjīvaka flower, and the white flower or bright white cloth of Vārāṇasī — training ever finer, ever more total mastery over how form itself is resolved by the mind. The first two bases of mastery take the first liberation as their basis, the third and fourth the second liberation, and the fifth through eighth extend the third liberation's purity into the four colors. The ten bases of totality then extend this same mastery outward without limit: totality of blue, yellow, red, and white, of earth, water, fire, and wind, and finally of the sphere of infinite space and the sphere of infinite consciousness — a bodhisattva who has truly mastered these can transform great into small and small into great at will, so that what he resolves upon is actually accomplished, common earth truly becoming usable, lasting gold rather than an illusion that evaporates. Alongside these three formal sequences, Master Cháng Bǎi notes, a bodhisattva should also master the further samādhis the treatise names elsewhere — the noble fivefold wisdom-samādhi, the noble fivefold-branch samādhi, and others — since real facility across every kind of object and every kind of resolve is what majestic power actually consists in. With this sixfold account of skillfully knowing mind's arising, abiding, emergence, increase, decrease, and means of application now complete, the Buddha's closing line affirms that a bodhisattva who has mastered all six either has already induced, will induce, or is even now inducing the whole of a bodhisattva's vast majestic power — bringing the treatise's twenty-fifth door, on inducing majestic power, to its close.

Master Cháng Bǎi opens the treatise's twenty-sixth and final door, on the extinguishing of feeling in nirvāṇa, by noting that a being's retribution comes in two kinds — the fruit of one's own person, and the fruit of the objects one experiences — and the two feelings named here correspond exactly to these. The feeling that has coarseness as its basis is the feeling belonging to one's own body and mind, the very retribution-body itself, produced by afflictive seeds and therefore inherently coarse, unyielding, and lacking the pliancy and capability a purified body would have — the *Sub-commentary* glosses it specifically as the ālaya-consciousness's own neutral feeling, since the retributive basis itself already carries this coarse quality. The feeling that is the fruit and object-domain of that basis is the feeling produced by experiencing external objects — what Master Cháng Bǎi calls the environmental increase-fruit. At the moment of nirvāṇa without remainder, the five aggregates cease with no further moment arising, so that both the basis itself and the objects it experiences, the personal fruit and the environmental fruit alike, are extinguished together without remainder. He also surveys the *Sub-commentary*'s three variant glosses on the pairing — reading the first as feeling based on the six sense-faculties and the second as feeling arising from the six external objects those faculties engage; or reading the first as the seed-level feeling and the second as its resulting current activity; or reading the first as feeling tied to the internal faculties themselves (carrying the coarseness of the two obstructions' seeds) and the second as feeling arising from the objects those faculties engage — noting that these correspond to what the treatise elsewhere calls, in its account of dependent arising, the feeling of one's own being and the feeling of one's surroundings.

Master Cháng Bǎi unpacks the first fourfold set plainly: feeling based on what has form is bodily feeling, arising when the five material sense-faculties contact their objects and generate the five sense-consciousnesses; feeling based on what is formless is mental feeling, the sixth consciousness's own experience; feeling whose fruit has already been fully ripened is this present life's bodily and mental feeling; and feeling whose fruit has not yet been fully ripened is the feeling belonging to a future retribution already fixed as a seed by present karma but not yet actually undergone — an unwholesome or wholesome cause already sown, its result still pending. He notes the moral drawn out explicitly here: whether one's future feeling will be predominantly pleasant or painful depends entirely on the balance of wholesome and unwholesome karma one is sowing now, a matter for which no circumstance and no other person can be blamed, since even one's circumstances are themselves a ripened fruit of one's own prior action. The second fourfold set concerns feeling tied to the objects one relies on and consumes. The feeling of what one relies upon and is sustained by covers six kinds of support the *Yogācārabhūmi* names in its opening ground (juan 2): the very basis that lets beings stand upright rather than float or sink (wind-, water-, and earth-wheels together), shelter from wind and rain (dwellings, whether built, found ready-made as in a cave, or spontaneously manifested as in the heavens), abundant harvest (the food that sustains any embodied being), security from violence (whatever protects beings from harm, whether human governance or, among animals, a herd's own leader), the sun and moon (without which nothing, plant or animal, could see or grow), and the four foods (morsel-food, contact-food, volitional food, and consciousness-food, morsel-food belonging to the desire realm alone and the other three pervading all three realms in varying combinations). The feeling of resources and requisites covers the same source's tenfold list of what beings actually consume day to day: food, drink, vehicles, clothing, ornaments, song and dance and entertainment, perfumes, garlands, and unguents, household implements, lighting, and sexual activity — a catalogue meant to cover the full range of what different beings, by their differing karma, actually rely on to get through each day. The feeling of actual enjoyment is the pleasure or pain, in whatever proportion, that beings across the three realms and five destinies actually experience as ripened retribution — humans a mixture of both, heavenly beings mostly pleasure, hell-beings unrelieved pain, hungry ghosts and animals mostly pain with little pleasure — and the feeling of longing attachment is simply the instinctive, universal urge to look after and cling to one's own body and possessions. Together these eight — four of coarseness, four of its fruit in objects — comprise everything nirvāṇa without remainder must, and does, bring to a final end.

An arhat still possessing a body — retribution not yet exhausted, hence "with remainder" — but with every view- and craving-based affliction utterly severed, hence still "nirvāṇa," has already extinguished every future, not-yet-ripened seed of feeling, since there is no further rebirth left to ripen it. What such an arhat still experiences, Master Cháng Bǎi explains, falls into three kinds. First, feeling born from the contact of clarity: an arhat's six faculties still meet their six objects, but every such contact is now suffused with wisdom — possessed of the knowledge of exhaustion and the knowledge of non-arising — abiding always in the highest equanimity, free of self-grasping and the ignorance that would otherwise color any contact. Second, feeling shared in common: an arhat emerging from non-discriminating wisdom still walks, still begs for food, still eats and sleeps like anyone else, sharing in the very same environmental retribution as other beings around him. Third, the feeling whose fruit has already been fully ripened: an arhat may still, before entering final nirvāṇa, experience headache or illness, a leftover fruit of past karma — but Master Cháng Bǎi is emphatic that this must never be mistaken for an ordinary being's suffering, citing the *Sūtra of Various Matters*' account that an arhat "has the blazing aggregates but not the five aggregates [as ordinarily grasped] — everything appears, but he is not attached to it; there is form, feeling, perception, formation, and consciousness, but no birth-and-death." Though the bodily aggregates still show signs of change and apparent suffering, the arhat's mind is not actually afflicted by form, feeling, perception, formation, or consciousness at all — such episodes occur only to demonstrate that cause and effect are never voided, a teaching device for beings still caught within it. He cites Śāriputra, who suffered from rheumatism yet had his own disciples carry him to hear the Buddha teach rather than miss the chance, and Maudgalyāyana, savagely beaten by rival ascetics yet composing, as he lay dying, a verse of utter equanimity — "why should I still cling to this body of pus and blood, bearing every suffering without rest; now that the venom of the serpent is entirely purged, I go in peace toward the city of nirvāṇa" — as living proof that an arhat's experience of what looks, from outside, like the same suffering an ordinary being feels, is in fact something entirely different from within.

At the moment of final nirvāṇa, even the one feeling an arhat still carried through nirvāṇa with remainder — the clarity-suffused contact-born feeling — is itself finally extinguished, and it is precisely this that the Buddha's original statement, quoted at the very opening of this door, was referring to. Master Cháng Bǎi appends a substantial gloss, drawn from the *Sub-commentary*'s citation of the Decisive-Discussion chapter (juan 73), on why the vessel-world itself does not simply vanish when a single being attains liberation: some appearances, like an individual's own six faculties, arise from that individual's own private discrimination alone and cease when that discrimination itself ceases or when one enters nirvāṇa without remainder; but appearances like the mountains and rivers of the shared world arise from many beings' discrimination held in common, and so, even when a particular sage's own discrimination of them is gone, they are still sustained by every other being's continuing discrimination and do not disappear — otherwise other beings' own karma would be left without any fruit at all. Though the shared world itself persists unchanged for everyone else, a being who has attained purity sees it with a purified, correct view even while still perceiving it: seeing a mountain and knowing it is, in the deepest sense, not a mountain, precisely as the *Diamond Sūtra* teaches that what the Buddha calls prajñāpāramitā is not, in that ultimate sense, prajñāpāramitā, and is for that very reason called prajñāpāramitā — an ordinary being who sees a mountain as simply a mountain will still walk into it, but a noble one who has pierced through to its true nature is no longer bound by it in the same way, capable of a freedom ordinary perception cannot touch, while still, outwardly, sharing the very same world everyone else inhabits. With this closing clarification, the treatise's twenty-sixth and final door, on the extinguishing of feeling in nirvāṇa, comes to its close — and with it, Maitreya's entire cycle of twenty-six questions on distinguishing calm-abiding and insight, opened at the very start of this fascicle's long dialogue, is now complete in full.

Having answered all twenty-six of Maitreya's questions, the Buddha now closes the entire teaching with praise and exhortation. Master Cháng Bǎi notes the weight carried by "excellent" repeated twice — not mere courtesy, but the Buddha's own affirmation that Maitreya's questioning has been perfectly matched to the teaching's own depth, since a question asked with true skill draws out an answer of equal value, and the whole of this fascicle's dialogue stands as proof of exactly that. The Buddha states plainly that what he has just proclaimed — the "perfect, utmost pure, wondrous path of yoga," meaning calm-abiding and insight practiced together as one indivisible path — is not particular to this one teaching occasion but is what every buddha of the past has already taught and every buddha of the future will yet teach, without variation: the content of enlightenment itself does not change from buddha to buddha, only the circumstances of its telling. Master Cháng Bǎi reads the closing charge to "good sons and good daughters" as extending the teaching's reach beyond bodhisattvas of Maitreya's own advanced attainment to every practitioner willing to apply real courage and diligence, since a teaching this exalted would otherwise risk feeling remote from an ordinary reader's own practice — a final reminder that the entire twenty-six-door structure just completed, however rarefied its content, was never meant only for the already-accomplished.

Master Cháng Bǎi walks through all five verses in turn. The first states the whole teaching's stakes in one stroke: negligence within the provisionally-named teaching of yoga forfeits the "great meaning" — nirvāṇa's own fruit — while correct practice attains great awakening; gain and loss are laid out as directly as cause and effect. The second verse warns against the subtlest failure mode of all: a practitioner who still holds some notion of "having attained" while seeking escape from saṃsāra's dangers, who mistakes this very view of attainment for the attained Dharma itself — believing, say, that a mental image of suchness arising in meditation is suchness genuinely realized — remains, Master Cháng Bǎi stresses, as far from true yoga as the solid earth is from empty space, no matter how much genuine effort has gone into the practice; he cites the *Sūtra Requested by Brahmā Viśeṣacintin*'s parallel warning that whatever the mind still discriminates is thereby already false, and only what is free of discrimination is correct, and the *Mahāvibhāṣā*'s own image of space and earth, of the two shores of an ocean, of sunrise and sunset — all vast distances — as still lesser than the distance separating true view from false. The third verse, on Master Cháng Bǎi's reading (shared with Master Yǎnpéi, Elder Miàojìng, and Master Woncheuk, though the *Sub-commentary* reads it somewhat differently), teaches the bodhisattva's twofold practice of benefiting others without grasping and benefiting others without ceasing: a bodhisattva's compassion is utterly firm, yet carries no notion of a self who benefits or an other who is benefited, and having realized this signless truth continues diligently helping beings anyway, sustaining this exactly balanced practice across three full incalculable eons until the supreme, undefiled joy of buddhahood is reached. The fourth verse rebukes a corrupted motive for teaching: one who ostensibly renounced worldly desire to enter the teaching, only to teach the Dharma now for fame or material gain, is like a man who has inherited priceless treasure yet still wanders the roads begging — the incomparable wealth of the Dharma squandered for the sake of coins no greater than what any layperson already has. The fifth and final verse calls for the abandonment of contentious debate, noisy and mixed company, and all six kinds of idle discourse the *Sub-commentary* enumerates — perverse chatter, wasted chatter, competitive chatter, comparative belittling, boastful cleverness, and craving talk of worldly food and wealth — replacing all of it with the utmost diligence, undertaken for the sake of liberating both the heavenly and the human world, in this very teaching of yoga that the whole fascicle has now set forth in full.

Fascicle 77 closes exactly as several of the Saṃdhinirmocana's earlier chapters have closed: Maitreya asks the Buddha to name the teaching just given, so that it may be properly upheld and transmitted, and the Buddha names it "the teaching of the definitive meaning of yoga" — yoga here meaning the union of calm-abiding and insight explored across all twenty-six doors of this fascicle's long dialogue, and "definitive meaning" marking it, in contrast to teachings of provisional or expedient meaning, as a direct statement of ultimate truth requiring no further unpacking. Master Cháng Bǎi closes his commentary by dwelling on the fourfold harvest the sūtra itself records: six hundred thousand beings newly resolving on unsurpassed bodhi, entering the Mahāyāna path for the first time; three hundred thousand śrāvakas cutting off the current activity and seeds of affliction sufficiently to attain the pure Dharma-eye of stream-entry; one hundred fifty thousand śrāvakas exhausting every contaminant entirely and reaching arhatship's full liberation; and seventy-five thousand bodhisattvas already on the path attaining the vast intention of yoga just taught, a leap forward in their own practice of calm-abiding and insight. He cites the *Mahāvibhāṣā* (juan 157) on why a single teaching produces such varied fruit in different hearers — "the Buddha proclaims the Dharma in one voice, and each being, according to its own kind, attains its own understanding; all suppose the World-Honored One speaks in their own language alone, addressing only them" — closing his commentary on this fascicle by noting that the very same sixteen-hundred-year-old teaching, read here through Master Cháng Bǎi's own lecture notes, continues even now to meet each reader exactly where they are, exactly as it met that assembly at Vaiśālī. With this, the twenty-sixth door — and with it, the entire chapter distinguishing yogic practice that has run from the opening of this fascicle straight through to its final line — reaches its complete and proper close.
