Cultivating the Marks, and the Four Powers That Open Absorption

Master Cháng Bǎi explains the four accomplishments as a working sequence. First, repeatedly cultivating the attention itself lets one come to know the object as it truly is — its self-mark, common mark, suchness, and exhaustive extent. Second, sustained sound contemplation distances the very affliction it targets — the four obstacles of dullness, agitation, scatter, and attachment named in fascicle 11, and, more broadly, any affliction at all: contemplate desire as impure, suffering, impermanent, and selfless, and craving is pushed to a distance; but only if one does this again and again, for a single reflection is soon forgotten and cannot summon right mindfulness when a situation demands it. Third, the practice "refines" both the attention (a mental factor) and its accompanying mind — he likens it to smelting gold, burning off the dross so that each successive moment of mind arises brighter and stronger.

The fourth accomplishment he unfolds as the full path in miniature, exactly as with the "counteracting attention" of fascicle 11: wearying of and breaking down the object (厭壞所緣) is the preparatory path, loosening a desire-realm being's attachment to sights, sounds, and the rest through the impurity contemplation; casting off the afflictions is the uninterrupted path that, resting on the threshold concentration, severs their manifestation and even their seed; holding firm to their severance is the liberation path, where the lower ground's afflictions are gone and one attains the first dhyāna or the first fruit; and making the afflictions withdraw from the continuum is the path of distinction, pressing on to cut the subtler afflictions still remaining, layer by layer. This is why, he stresses, the whole apparatus of cultivating attention on the marks matters: it is the machinery of actual liberation, not mere technique.

Master Cháng Bǎi reads the four powers as two pairs: nature and effort, then self-reliance and reliance on another. The power of the cause is the force of seeds — one who cultivated absorption in a past life (or earlier this life) finds the entry-signs of a dhyāna arising as he approaches, and knows he will soon enter; he recalls a pilgrim-monk who mastered in three years what normally takes ten, simply because his prior cultivation was so strong. The power of method is present effort: even without that stock of seeds, unbroken and repeated cultivation can open the concentrations — where the first power is innate endowment, this is acquired diligence.

The power of teaching and the power of instruction he ties to the two classical faculty-types. One who enters by the power of teaching is the follower-by-Dharma (隨法行), of sharp faculties: having widely heard and firmly retained the meditation teachings — knowing, when he sits, exactly how to practice breath-counting or the impurity contemplation and what states will arise — he then withdraws to solitude, sheds heedlessness, drives himself valiantly, and practices the Dharma in accord with the Dharma (the "Dharma" being the goal, nirvāṇa; the "in accord with" being the eightfold path). One who enters by the power of instruction is the follower-by-faith (隨信行), typically of duller faculties but strong confidence: he receives undistorted instruction from a genuine teacher — the impurity contemplation, or that all formations are impermanent, all contaminated things suffering, all dharmas selfless — and, because the guidance accords with the scriptures, he can trust it and enter. Cháng Bǎi adds the practical caution that even the follower-by-faith should read the treatises himself, so as to verify that a teacher's instruction truly matches what the scriptures say.

Master Cháng Bǎi frames all four attainers as cautionary: absorption reached without the Dharma's own corrective becomes a trap. The relisher has heard only that the dhyānas bring joy, sublime bliss, stillness, and imperturbability — never that the contaminated aggregates they rest on are still "like a sickness, like a boil, like an arrow," still impermanent, suffering, and selfless, and that one must seek release from them too. So having driven himself into absorption, he emerges relishing its flavor, leaving genuine "pure concentration" for a "concentration of relish," his mellowed temper fooling him into thinking his afflictions are gone. Cháng Bǎi repeats Miào Jìng's constant warning: never practice concentration apart from the scriptures, or you will mistake the first dhyāna for the first noble fruit — the very "conceit of overestimation" the whole ground keeps guarding against.

The view-attainer is worse off, because his absorption actively serves a wrong view. Taught by a non-Buddhist teacher that self and world are permanent — the eternalism the treatise refuted at length back in fascicle 6's sixteen-doctrine survey — he uses the recollection of past lives that absorption unlocks to "confirm" it: "I existed life after life, my mind flowing on unbroken, so I and the world must be permanent." Having only the concentration and no insight into dependent origination, he emerges gripping the view all the harder, and mistakes what he calls "purity, liberation, and release" — really just the meditative suppression of desire — for genuine escape from saṃsāra. Cháng Bǎi notes the decisive contrast: one who has truly seen the truths needs no such anxious re-examination afterward, because direct realization, unlike a meditative inference, does not have to keep reassuring itself.

Master Cháng Bǎi notes that the conceit-attainer's absorption is genuine but stained: because conceit rides along with it, the concentration is never "perfected, pure, and bright" — pure meaning free of affliction, bright meaning continuously so — which is exactly why he must keep re-examining it afterward, uneasy beneath the pride. His conceit takes two forms, ranking himself equal to those who have attained ("why not I?") and then superior to those who have not ("only I can do this").

The doubt-attainer, he explains, is a dull but karmically unobstructed type with a real past-life fondness for calm, so he reaches worldly absorption readily; but his slowness with dependent origination keeps him from breaking through to direct realization of the four truths, and, seeing others apparently attain what he cannot, he slides into doubt — doubting whether there is any noble path to be reached at all — and so keeps anxiously scrutinizing as he tries to advance. Cháng Bǎi's throughline for all four flawed attainers is the same: absorption reached without genuine insight is unstable and forever re-checking itself, whereas one who has actually seen the truths, having directly realized reality, needs no such reassurance.

Master Cháng Bǎi frames the three concentrations — relish-associated, pure, and uncontaminated — as the classical triad also found in the Abhidharmakośa. The first is the trap of the dull, greedy, or heavily-afflicted who have heard only that absorption is pleasant: not knowing how to press on to the higher release, they settle in and cling to the flavor. He draws out the treatise's precise phrasing — "what is relished should be called 'already left,' the relishing 'just entered'" — to make a sharp point: relish never actually occurs within pure concentration; it arises only once one has come out of the pure concentration and slipped into a "concentration of relish." So the pure absorption is the thing relished (now left behind), and the relishing is the tainted state just entered. He notes relish comes in three modes — savoring a past attainment in memory, craving a future one, and clinging in the present.

Pure concentration belongs instead to those of middling or sharp faculties whose temperament is "even-affliction" (every affliction present but all mild, from a past life of little indulgence) or "thin-defilement" (afflictions light, and their faults already clearly seen). Because such a practitioner has heard not only of absorption's merits but of its relish-fault and of the release to be won beyond it, he enters without clinging: once in, he can still contemplate the concentration's own faults and see the higher release, so no relish takes hold. Cháng Bǎi stresses that even a genuine root-absorption is not yet "perfected, pure, and bright" so long as relish, conceit, view, doubt, or ignorance can still stain it — which is why seeing the faults, not just the merits, is what keeps a concentration pure.

Master Cháng Bǎi identifies uncontaminated concentration as the possession of the noble follower-by-faith or follower-by-Dharma of thin-defilement temperament — either one who has already realized the four truths (and is thus a noble one) or one now on the direct-realization path. Its mark is a hard-won ease: the beginner must deliberately raise three things to enter absorption, but the adept no longer needs to think them at all. He glosses the three: practice (行) is the coarse-versus-calm contemplation — seeing the lower ground as coarse and yearning toward the higher as calm, the six-aspect method that lifts one from ground to ground; state (狀) is the cluster of entry-signs that arise as the elements shift at the threshold of absorption, by which both the meditator and his teacher can tell which concentration he is about to enter; and object (相) is the two marks already given — the object-mark (the image the discriminating mind projects) and the causal mark (the concentration-provisions of precepts, sense-restraint, moderate eating, and clear comprehension).

On the "state" or entry-signs, Cháng Bǎi points to Zhiyi's account of the first dhyāna's arising — where, out of the threshold concentration's deep stillness, the body settles into a motionless "congealed" quiet and then a subtle movement rises (from the crown, the feet, or the waist), attended by a cluster of wholesome factors: one-pointed concentration, a sense of spacious emptiness, luminous purity, joy, bodily bliss, a wholesome mind, clear knowing, and an unburdened release. He keeps only the theme rather than reproducing the passage, consistent with the discipline of synthesizing secondary sources; the point for the treatise is simply that the practiced adept, having entered so often, no longer needs to summon any of these marks deliberately — the uncontaminated concentration opens of itself.

Master Cháng Bǎi stresses the decisive point: an absorption becomes uncontaminated only when insight is layered onto the calm. The practitioner turns on his own five aggregates — form, feeling, perception, formations, consciousness, including the very refined aggregates of the absorption he is in — and contemplates them as a sickness that constantly aches, a boil oozing the pus of affliction, an arrow, a barb, a killer, impermanent, suffering, empty, and selfless; toward everything conditioned his mind generates revulsion, dread, and active subdual of its own clinging. He notes the treatise's "and so on" (如病如癰等) reaches through the full range of what an out-of-the-world absorption contemplates — impermanence, suffering, emptiness, non-self, the four truths, suchness, dharma-nature, and the real limit (citing the Xianyang Shengjiao Lun).

Finally, he fixes his mindfulness on the "deathless realm" (甘露界, amṛta) — nirvāṇa itself, the truth of cessation, the peace of all phenomena's stilling — which Cháng Bǎi glosses (with the Ground of the Nirvāṇa-without-Remainder) as another name for the nirvāṇa-without-remainder into which the śrāvaka enters on laying down the aggregates. His practical warning is exact: merely counting the breath without seeing the breath as impermanent, suffering, empty, and selfless, or contemplating impurity without pressing on to the same, can never accord with an uncontaminated concentration. The calm is the base; the insight into the aggregates' faults and the mind fixed on cessation is what makes it uncontaminated.

Master Cháng Bǎi maps the four "shares" (順退／住／勝／決擇分) onto four trajectories. The retrogression-prone practitioner has dull faculties and only a feeble aspiration; he is diligent enough to enter absorption, but cannot bear its sublimity — joy (the first two dhyānas), bliss (the first three), and the supreme merit of the fourth's imperturbable equanimity — and so keeps slipping back out. Miào Jìng's image: a poor man who suddenly wins a fortune, so unaccustomed to wealth that he cannot rest until he has spent it all back to normal. What such a one lacks is the patience to "temper the faculties" (調練諸根 / 練根) — the sustained work, drawing on the five motives named in the Viniścaya, that turns dull faculties into middling and sharp — so he enters and falls, enters and falls. The stability-prone practitioner has middling or sharp faculties but has heard only of absorption's merits, so he relishes what he attains and simply stays there: his diligence keeps him from falling, but ignorance of the release keeps him from rising.

The advancement-prone practitioner has the same faculties but has also heard the means of release; never content — not with the first dhyāna, not even with the fourth — he relishes nothing and keeps seeking a higher station, and so genuinely advances. The penetration-prone is the decisive one: "penetration" (決擇) is the decisive discernment of insight (vipaśyanā), and by deeply seeing the faults of all "self-embodiment" (薩迦耶 — the innate craving-for-a-self that, Cháng Bǎi notes, pervades all three realms and is the root support of every affliction: "where there is defiled desire in one place, there is defiled desire everywhere") such a one enters the uncontaminated. He draws out the treatise's own gem-sorting simile: as a jeweler who has picked out every finest stone has nothing left to sort, so non-self insight is the final discrimination — past it there is nothing more to examine, no more anxious re-checking, which is exactly why the uncontaminated, reached through it, is called "penetration."

Master Cháng Bǎi ties the two to a difference in purity. Unbroken entry belongs to one who possesses all eight attainments but is "not yet perfectly pure and bright" — his mind still stained by the relish, conceit, view, doubt, and ignorance the dhyānas breed; to strengthen his command he runs the whole ladder without a gap, forward from the first dhyāna up to the peak of existence, then in reverse all the way back down. Leaping entry belongs to one who has cleared those stains and reached sovereignty over the attainments (三摩地自在): he can skip exactly one station — first to third, third to the sphere of infinite space, that sphere to the sphere of nothingness, and the same in reverse — but never two at once, because the object-signs of stations two apart are simply too far to bridge.

He notes the single exception: a Tathāgata, and a bodhisattva who has passed the second of the three incalculable eons (the eighth ground and above), can enter any concentration whatever at will, with no restriction of sequence or distance — a single act of attention carrying them from the first dhyāna straight to the peak of existence. Cháng Bǎi reads this as a window onto the mind's boundless latent capacity: what looks impossible is only untrained; a mind cultivated across those eons moves instantly where an ordinary practitioner is stalled for a lifetime in scattered states.

Master Cháng Bǎi explains permeation-cultivation (熏修) as deliberately interleaving the two kinds of absorption a practitioner already commands: the contaminated dhyāna cultivated by the coarse-versus-calm ascent, and the uncontaminated dhyāna cultivated by contemplating the four truths and non-self. One does a long stretch of the contaminated, then a short stretch of the uncontaminated — perhaps thirty minutes of the one, five of the other — gradually lengthening the uncontaminated and shortening the contaminated, until the two can follow each other with no gap at all. The purpose is to steady the absorption against the relish, conceit, view, and doubt that would otherwise erode it, so that it becomes "pure and bright" and no longer retrogresses. He notes that a threshold concentration is hard-won and easily lost, and even the dhyānas above it can be lost; permeation with the uncontaminated is what finally makes them secure.

Mastery (自在) is then the ability to enter any concentration at whatever place (each dhyāna-level with its grades), time (day or night), and object one wishes, with no difficulty or snag. Its four fruits Cháng Bǎi lines up: the present pleasant abiding grows steadily brighter and purer (Miào Jìng's candle-power image — a twenty-watt and a forty-watt bulb both give light, but the stronger gives a clearer, steadier one); the path becomes non-retrogressing; and it purifies the path that elicits the supreme qualities — the eight liberations (severing the afflictions of all nine grounds), the eight masteries (mastery over the visualization objects), the ten totalities, and beyond them the concentration of non-contention, the knowledge-of-vows, and the four analytic knowledges. The fourth fruit is rebirth: one who dies still carrying a "remaining grasping" — not desire-realm grasping, but a residual form-realm craving with innate self-grasping not yet fully cut — is reborn spontaneously in the Five Pure Abodes (無煩・無熱・善現・善見・色究竟), the fourth-dhyāna heights inhabited only by non-returners.

Master Cháng Bǎi lays out the rebirth-grades, referring back to fascicle 4's fuller account: each dhyāna cultivated in soft, middling, or superior grade yields rebirth in that dhyāna's three heavens (soft, middling, and superior first-dhyāna practice giving the Brahmā-multitude, Brahmā-ministers, and — via the "only-sustained-thought" intermediate concentration between the first and second dhyānas — the Great Brahmā himself; and likewise up through the fourth). The five finer grades of permeation-cultivated fourth dhyāna — soft, middling, superior, super-superior, and utmost — yield the Five Pure Abodes, which, being reserved for non-returners, ordinary beings never reach (they attain only the fourth dhyāna's Cloudless, Merit-Born, and Great-Fruit heavens).

He then draws out three points from the "clarification." First, rebirth in the form heavens comes only from pure dhyāna; a relished dhyāna makes one fall away, and only renewed pure cultivation restores the rebirth. Second, one must actually attain the dhyāna in this present desire-realm life to be reborn in its heaven — for no one reaches the form realm without leaving desire, and no ordinary being leaves desire without the dhyāna. Third, and strikingly, the bliss of the absorption itself is exactly the same whether experienced in a desire-realm body or a form-realm one; what differs is only the karmic support-body. The lower dhyāna is the "lower concentration," each higher one the "higher," and from a desire-realm body a practitioner's form-realm craving arises toward whichever level he has cultivated — carrying him there at death.

Master Cháng Bǎi frames this closing division as the treatise turning from its own systematic analysis to the meditation teachings as the sūtras present them — beginning with the eight liberations (八解脫, also called the eight releasings, 八背捨), the eight masteries (八勝處), and the ten totalities (十遍處), which together are the foundation for the superknowledges and the concentration of non-contention. The eight liberations are, in effect, the nine successive attainments: the first two contemplating form (to release craving for form), the third the "pure liberation directly realized in the body" (deliberately contemplating a beautiful object to prove mastery is genuine), the fourth through seventh the four formless spheres, and the eighth the cessation of perception and feeling.

On the naming he is precise. The first seven are called "liberation" not because one is only now freed — attaining any given level already means one has left the lower ground's affliction — but because one generates an intensified conviction (勝解) toward that already-won release, driving the severance deeper and making the attainment more sovereign and stable, so it will not slip back. The eighth is called "liberation" in a different sense: it casts away the very apparatus of perception and feeling, a near-nirvāṇa rest available only to non-returners and arhats. Cháng Bǎi notes in passing that the traditions differ on which dhyāna each liberation rests upon and exactly what is contemplated — the Kośa and this treatise diverge, especially on the second liberation — and treats these as school differences to be noted rather than adjudicated, the deeper lesson being that all of it is accomplished by sustained, deepening contemplation: the more clearly and repeatedly one contemplates an object, the more thoroughly its affliction is subdued.

Master Cháng Bǎi flags the distinctive point of this treatise's first liberation. A beginner contemplates form as impure to break craving; but the practitioner of the first liberation has already left desire-realm craving on attaining his form-realm concentration, so he contemplates desire-realm forms instead with a perception of luminosity (光明想). The aim is no longer to kill a craving that is gone, but to remove the obstacle to transformation — to gain sovereign command (勝解自在) over form. "Having form," Cháng Bǎi explains, holds in two senses: he still has a body, being born in the desire realm, and he uses a form-realm concentration (both realms having material form), plus he generates his conviction specifically toward luminosity. He notes the traditions differ on the supporting concentration and the object — the Kośa has the first liberation rest on the first dhyāna and contemplate impurity, whereas this treatise (following Asaṅga) allows any of the four dhyānas and a luminosity perception — a divergence to note, not resolve.

The forms contemplated are sorted as the first four of the eight masteries sort them: the "lesser forms" (少色) are beings' own bodies and everyday possessions — a desk, a robe, a bowl — small in size; the "many forms" (多色) are large things like palaces and houses; each is taken as good or bad in its visible color, inferior or superior in its sound, scent, taste, and touch. Cháng Bǎi underlines the treatise's own statement of purpose: the whole point of this contemplation is to "purify the path that can elicit the supreme qualities" — the eight masteries resting on it, the ten totalities resting on those, and beyond them the noble superknowledges, the non-contention concentration, the knowledge that fulfills vows, and the four analytic knowledges. Freedom from craving for form was step one; sovereign command over form, so that these powers can be drawn out, is what the first liberation now cultivates.

Master Cháng Bǎi reads the second liberation as a rung above the first: the practitioner has now left form-realm desire — that is, attained a formless attainment — so he no longer needs the internal perception of luminosity that the first liberation used. Resting on the formless attainment as his base (though not taking its formless objects — space and the rest — as what he contemplates), he generates conviction only toward "external" forms, where "external" precisely means forms he has already freed himself of desire for. He notes the schools diverge sharply here — the Kośa has this liberation rest on the second dhyāna and contemplate impurity, while this treatise grounds it in a formless attainment — and treats the divergence as a matter of lineage, the shared point being the removal of the obstacle to transformation.

The third, the pure liberation, rests on the fourth dhyāna's "perfected, pure, and bright" equanimity and mindfulness, and cultivates the three perceptions of pure-and-impure form: mutual dependence (pure and impure exist only by contrast), mutual inclusion (purity within impurity and impurity within purity — the human body's "thin skin covering the unclean" that fools the eye into seeing it as lovely), and single taste (all resolved into one pure, luminous perception radiating blue, yellow, red, and white), until transforming form to pure or impure at will becomes effortless. It is called "pure" for three reasons Cháng Bǎi aligns exactly: having passed beyond pain and pleasure yields the pure equanimity; all agitation stilled (of thought, breath, even the three cosmic calamities) yields the pure mindfulness; and being "well polished" is the mastery of the pure-impure transformation itself. "Directly realized in the body" marks this and the eighth liberation as the two the noble ones dwell in most — cultivated only by third-fruit sages and above; and the first three liberations together form the base on which the eight masteries are built.

Master Cháng Bǎi explains that each of the four formless liberations takes a sphere the practitioner has already attained and, by generating an intensified conviction (勝解) toward its object, drives out the remaining obstacle and makes the attainment sovereign and secure — the aim throughout being to unlock the noble superknowledges, the non-contention concentration, the knowledge-of-vows, and the analytic knowledges, not to remove a craving already gone. Space-liberation fixes conviction on space as boundless; consciousness-liberation, on consciousness as boundless; nothingness-liberation, on the recognition that even boundless consciousness is "nothing at all." The peak-of-existence liberation (neither-perception-nor-non-perception) has no further object to convince toward: it releases both the "something-is-there" perceptions of the space and consciousness spheres and the "nothing-is-there" perception of the nothingness sphere — which is exactly why it is called "neither perception nor non-perception."

He flags one careful point, following Kuiji: the treatise pointedly does not say the practitioner has "left desire" for the top two spheres, because these are the practice of third-fruit non-returners, who still carry innate self-grasping — only an arhat has fully left the desire of all three realms. So for these the language is "releasing and stabilizing the lower ground" rather than "leaving desire." Cháng Bǎi closes by noting the many school variations on which concentration each liberation rests upon, and that this treatise names all eight together "the eight noble abidings" — the first seven called liberation for the intensified conviction toward an already-won release, the eighth for casting away perception and feeling.

Master Cháng Bǎi explains that before liberation the object dominates the mind, dragging one through the six destinies; once the eight liberations are mastered and contemplation ripens, the mind grows stronger than the object, so that "all objects turn according to the mind" — this reversal is what "mastery" (勝處, literally "outdoing-station") names. "Sovereign knowing" (勝知) comes by the power of calm, able to make an object vanish; "sovereign seeing" (勝見) by the power of insight, able to turn it at will. He lists the five senses of the word: outshining (a superior skill puts another's in the shade — a non-Buddhist's powers outshone by a śrāvaka's, a śrāvaka's by a bodhisattva's, a bodhisattva's by a Buddha's); overpowering (the strong subdues the weak — a stream-enterer's non-self insight crushing the surge of self-love at the moment of death); concealing (a jar hides what is behind it; herbs, mantras, or powers hide an object — sunrise concealing the stars and lamps); wearying (wearying of the object so as to cast off affliction, on both the worldly and the world-transcending paths); and sovereign turning (a king disposing of his servants at will — seeing much as little and little as much).

The eight masteries themselves pair internal form-perception (or its absence) with contemplating external forms as "little" (beings and their possessions) or "much" (palaces and houses), each sorted good/bad/inferior/superior, and the last four take the four colors — blue, yellow, red, white. What the masteries add beyond the liberations, Cháng Bǎi stresses, is exactly concealment and sovereign turning: the liberations won sovereign conviction over form, the masteries win sovereign subdual of it. And "perception of subdual" (制伏想) means commanding the object completely — turning blue to yellow, pure to impure, little to much — without a trace of self-overestimation. He recounts the story of Venerable Aniruddha, whom four dazzling celestial women, able to transform into any color at will, offered to serve: he tried the impurity contemplation on them through all four dhyānas and through every color he asked them to display, and could not raise a single impure perception — his concentration and their color-mastery were "like two wrestlers of equal strength, neither able to prevail." The point, Cháng Bǎi notes, is that a sharp-faculty great arhat like Śāriputra, whose sovereign concentration exceeds any object, would have overpowered them — mastery is a matter of degree.

Master Cháng Bǎi lists the ten: earth, water, fire, wind (the four elements, as touch), blue, yellow, red, white (the four colors, as form), plus space and consciousness. A "totality" (遍處) generates a conviction that its object fills the whole of space without any boundary — contemplate earth, and everywhere is earth; and likewise for each. "Non-dual" because the noble one contemplates these without any grasping at self or mine; "immeasurable" because the sign pervades limitlessly. He explains why only form and touch furnish the objects, and not scent, taste, or sound: only visible color and the tangible elements are shared by one's own and others' bodies, pervade the entire form realm, and are constantly continuous — whereas the sense-faculties belong to one's own body alone, scent and taste do not even exist in the form realm, and sound is intermittent, arising only on occasion. The ninth totality, space, is built at the very edge of the form realm, contemplating form dissolved into an all-pervading space; and the tenth is consciousness, contemplating consciousness pervading all.

He treats the eight liberations, eight masteries, and ten totalities as one graded ascent of command over the material and formless attainments — the liberations winning sovereign conviction, the masteries sovereign subdual, and the totalities sovereign pervasion — and as together the finest foundation for the noble superknowledges and the transformative powers the ground has been pointing toward throughout.

Master Cháng Bǎi notes that the consciousness-totality contemplates consciousness pervading everywhere, completing the ten, and draws out the strict developmental sequence the three sets form: with the liberations one first generates sovereign conviction toward the object, winning command over it; with the masteries one subdues it, able to conceal and turn it; and with the totalities, having gained that mastery, one generates conviction that it pervades all of space, however one wishes. Each set presupposes the one before.

He then lines up the powers each unlocks once purified: the eight form-totalities (the four elements and four colors) elicit the transformation superknowledges — whatever one is convinced of, so the thing transforms, even into gold or silver fit for actual use; the consciousness-totality elicits the non-contention concentration, the knowledge that fulfills vows, and the four analytic knowledges; the space-totality turns anything at will into space. The potter's image crowns the whole triad: the liberation-stage is like clay first mixed but not yet worked; the mastery-stage like the clay now skillfully kneaded; the totality-stage like the finished command that shapes the worked clay into whatever form one pleases — the graded mastery over form and the formless that founds every transformative power.

Master Cháng Bǎi introduces the emptiness concentration (空三摩地) as the first of the three doors to liberation: the mind fixed single-pointedly on the fact that behind the aggregates there is no being, no living soul, no nurturer, no transmigrating person — none of the things the various words for a self name. He distinguishes its four kinds. Investigative emptiness is the analytic insight that sees all phenomena as empty of permanence, of pleasure, and finally of self and mine. Its fruit-emptiness is what that insight wins — the "unshakable liberation of mind" of an arhat, empty of craving and every affliction. Internal emptiness is one's own body and aggregates seen as empty of any I, mine, self-conceit, or crooked grasping. External emptiness is the five sense-objects seen as empty of the craving-for-desire they provoke — glossed through the scriptural line "having transcended all perceptions of form," where "perception of form" means the perception of desirable objects, so that "external emptiness" names the severing of the craving that such perception sets off.

He notes the method interweaves the four: standing in the fruit-emptiness, the practitioner alternates his attention between external and internal emptiness; and through investigative emptiness he attends to internal-and-external emptiness together, until the force of that contemplation lets the mind realize both at once. This is the first of the three concentrations; the wishlessness and signlessness concentrations follow.

Master Cháng Bǎi notes that the mind is complex, so a single angle of contemplation may not sever an affliction; when direct contemplation of internal and external emptiness fails to land, one adds "the unwavering" — the perception of impermanence or of suffering. Seeing the aggregates as impermanent and suffering, self-conceit, self-view, self-love, and self-delusion lose their purchase, and the mind, no longer moved by any reckoning of a self, realizes both the internal and external emptiness at once. He underlines the balance the treatise draws (via the Compendium of Ascertainments) between wrong and right emptiness: a genuine see-er of the truths avoids the "wrong emptiness" of nihilistic blankness and enters the "right non-emptiness" of dependent arising — the aggregates are not utterly nothing (they arise illusorily by conditions and must be "known as existent"), yet they are empty of any real self; the five sense-objects are not nothing, but the craving for them is to be severed. This is what contemplating internal-and-external emptiness truly means.

The wishlessness concentration (無願, the second of the three doors to liberation) then fixes the mind single-pointedly by contemplating the five grasping-aggregates as impermanent, or as suffering — suffering-of-pain, suffering-of-change, suffering-of-formations — so that no fondness for form, feeling, perception, formations, or consciousness arises, and no craving for further existence is generated. The mind rests wishless, its grasping stilled. "Grasping" (取), Cháng Bǎi glosses, means clinging: beings' consciousness perpetually clings to the aggregates, which is why they are called the "grasping-aggregates."

Master Cháng Bǎi explains that the signless concentration (無相, the third door) fixes the mind on the quiescent unconditioned — the cessation of the five grasping-aggregates — withdrawing from all signs. Following Kuiji, he answers why "wishlessness" and "signlessness" carry the word "mind" (心) while "emptiness" does not: the emptiness concentration directly contemplates non-self, which accords with the empty itself, so no "mind" is added; the other two contemplate upon the conditioned aggregates, so "mind" is added. The "signs" to be removed are the classical set — the five sense-objects, greed, hatred, delusion, and male and female (ten), sometimes given with birth, aging, and death, or with suffering, pleasure, and equanimity added — in short, the whole range of conditioned marks the mind fastens on.

"Neither low nor exalted" he reads two ways. First, it corresponds to neither the repellent sign (the conditioned aggregates, whose faults make the mind sink in aversion — "low") nor the agreeable sign (the signless realm, whose merits make the mind rise in attachment — "exalted"). Second, it names the two conditions of entry: not attending to any sign means one neither wearies of the signs nor tries to destroy them, but simply withdraws effortful attention from them — "not low"; and rightly attending to the signless realm while not clinging firmly to it — seeing its merit through sound attention but not grasping at it — is "not exalted." He notes the schools diverge on the term (the Mahāvibhāṣā treats "signless" as a synonym for the emptiness concentration, whereas this treatise distinguishes them as the intellect's fruit and its own distinct door).

Master Cháng Bǎi distinguishes the signless concentration's two phases. In the means-phase the beginner must keep spurring himself to establish the signless in mind — but, never having seen the genuinely signless, he can only fix a conceptual "sign of the signless" by name, and the sign-following consciousness (隨相識 — "following" meaning "resembling," the imagined signless that merely resembles the real one) keeps disturbing him. Through repeated effort he wins the fruit — real freedom from the sign-following. When that freedom itself becomes effortless — freed, and freed again, so that he enters the signless the moment he inclines toward it without any labor — it is "utterly-good liberation" (極善解脫); a liberation still requiring strained effort each time is liberation, but not the utterly-good kind, because the conceptual signless is only similar to the real, and only realizing emptiness itself, transcending the sign-following altogether, is genuinely effortless.

He gives the "fruit of clear knowing" and "merit of clear knowing" (曉了果／曉了功德) three readings, each pairing a result with what produces it: the final severance of affliction (fruit) with the final present pleasant-abiding (merit); the cessation-truth realized (fruit) with the path-truth that realizes it (merit); and the four-truths direct realization together with the fruit of arhatship, both penetrating the signless ultimate. With this the three concentrations — the three doors to liberation — are complete.

Master Cháng Bǎi glosses the three names cleanly: a thing is "empty" where it lacks something — the aggregates empty of any self; "wishlessness" because the emptiness one has seen leaves nothing to wish for, no craving for existence toward what has no self; and "signlessness" because it is contemplated as removed from every conditioned activity-mark. On the ordering, he explains that the usual teaching-sequence — impermanent, therefore suffering, therefore no-self, therefore empty — is reversed here, emptiness (no-self) placed first, for a structural reason: the contemplation of impermanence and suffering never becomes pure unless it is grounded in no-self, since otherwise one still covertly grasps an "I" that is impermanent and that suffers. So one must first stand in the perception of no-self; from that, wishlessness follows without interval (seeing no self to preserve, one ceases to wish for existence); and from that, signlessness (wishing only for the signless peace and single-mindedly seeking release). Cháng Bǎi cites the treatise's own scriptural support — "the perceptions of impermanence rest upon the perception of no-self" — to make the point that the three doors are a strict progression built on no-self, not three interchangeable techniques.

Master Cháng Bǎi notes this sorts concentration by applied-and-sustained thought (尋伺) as a psychological matter — reusing the very names (有尋有伺, 無尋唯伺, 無尋無伺) that ran cosmologically through fascicles 4–10, but here for states of mind, exactly as fascicle 11 flagged. The concentration with both is the threshold concentration and the first dhyāna, where coarse applied thought and fine sustained thought are both present. The concentration with only sustained thought is the intermediate dhyāna between the first and second, where coarse applied thought has dropped but fine sustained thought remains — and cultivating precisely this is what makes one the Great Brahmā King. The concentration with neither is the second dhyāna and above, up to the peak of existence, where both are stilled. He stresses that these three are the contaminated (worldly) concentrations, the ones that carry rebirth up the form and formless realms; the uncontaminated concentrations are excepted, because they generate no saṃsāric rebirth.

On the mark of the "neither" concentration: the mind casts off both coarse and fine thought, so that in place of thought's restless discriminations it rests in "a single flavor" — one even, level conviction toward the inner object, with none of the up-and-down of investigating. Cháng Bǎi treats this evenness of a single sustained taste as the felt signature of an absorption past all applied and sustained thought.

Master Cháng Bǎi explains the great-mind concentration (大心三摩地) as a light-visualization used to purify the first dhyāna: having wearied of desire and won that absorption, the practitioner, hearing that the gods' bodies glow, contemplates that radiance spreading from beneath his own tree out to the edges of the earth and ocean, generating a vivid conviction. He notes the light itself differs by level — the first-dhyāna gods glow only outward (like a maṇi-jewel, bright without but dark within), while the second-dhyāna gods and above glow both within and without (like a lamp) — which is why "from the second dhyāna up there is only one kind of body." He fills in the classical four kinds of form-beings by body and perception: body-different-and-perception-different (humans and some gods); body-different-but-perception-same (Brahmā's retinue at the start of an eon, all imagining themselves Brahmā's creation though Brahmā's own body towers over theirs); body-same-but-perception-different (the second dhyāna, one luminous kind of body but alternating pleasant and neutral perception); and body-same-and-perception-same (the third dhyāna's Universally-Pure gods, one body and one blissful perception).

He then traces the concentration's deepening through a strict "only-two" — inferior and superior — chain: the strength of one's conviction sets the attention as inferior or superior; that sets the cultivated concentration as inferior or superior; that sets the karmic formation (the imperturbable seed) as inferior or superior; and that in turn sets the reborn being as inferior or superior. This, Cháng Bǎi notes (citing the Xianyang Shengjiao Lun), is the very grading that gives each form-heaven its levels — attention, cultivation, karma, and person all moving in step from lesser to greater.

Master Cháng Bǎi lays out how the four immeasurables are built on the three kinds of beings and the wishes fitting each: loving-kindness (慈) toward the neutral being, wishing it happiness (countering ill-will); compassion (悲) toward the suffering being, wishing to pull its suffering out (countering harm); and sympathetic joy (喜) toward the happy being, wishing its happiness never to leave it (countering envy). Equanimity (捨) then takes the same three beings and adds a further, corrective aim: to free the neutral being from the delusion of longing after worldly pleasure, the suffering being from ill-will, and the happy being from craving — so that, having given happiness, removed suffering, and rejoiced, one now teaches each to release greed, hatred, and delusion, and extends one even, undefiled regard to all beings alike, past the partiality of friend and enemy.

He stresses (citing the Dàshèng Yìzhāng) that the four mutually assist and cannot stand alone: loving-kindness needs compassion actually to relieve suffering, and compassion needs loving-kindness actually to confer happiness; both need sympathetic joy to clear away the envy that would block them; all three need equanimity to become impartial rather than partial; and equanimity needs the first three, or it decays into mere indifference — the first three being "with-activity" and equanimity "space-like emptiness," each holding the other's excess in check. He adds that these are the noble ones' immeasurables, open also to ordinary beings and even non-Buddhists but differing in quality and in their supporting concentration — śrāvakas basing them on the four dhyānas, while great bodhisattvas and certain great arhats can base them even on the formless attainments.

Master Cháng Bǎi reads the formula term by term. "Accompanied by loving-kindness" is actually benefiting the being before one; "good friend of loving-kindness" is the benefiting-mark itself, of two kinds — wishing benefit (this life and the next, by transforming the being's mind and so its karma) and wishing ease (bodily and mental happiness), the two aims every immeasurable shares. The three negations map to the three doors of action: "without enmity" is freedom from ill-willed intent (mind), "without hostility" is freedom from present quarrel (speech), and "without harm" is freedom from un-benefiting deeds (body). "Vast" points to the immensity of the object — all beings of the ten directions and three times; "great," to the supremacy of the thought of their benefit and ease; and "immeasurable," to the boundlessness of the fruit, which he likens to the four great rivers whose many streams merge — all goodness gathered, so the merit has no measure (he recalls the classical fifteen benefits of loving-kindness: sleeping and waking at ease, dreaming no evil, guarded by gods and men, unharmed by fire, water, poison, or blade, reborn in Brahmā's world, and so on). "Well-cultivated" is the practice utterly ripened.

The summarizing phrase "resolved, pervading, complete, and abiding" he unpacks as the felt shape of a mature immeasurable: a heightened resolve (增上意樂勝解) — a settled, unshakable intention of benefit and ease — that reaches all-round to every being (resolved-and-pervading); perfect and pure, momentarily and continuously free of any defiled intent (complete); and sustained through day and night, moment after moment (abiding).

Master Cháng Bǎi shows each immeasurable reaching its height on a base whose character matches its own wish. Loving-kindness (already given) peaks at the third dhyāna, whose bliss is the finest in all three realms — so wishing beings that happiness is loving-kindness at its fullest. Compassion peaks at the sphere of infinite space, because the wish to remove suffering is answered most completely where the formless realm has already shed every bodily suffering — the "breaking and injury" a body undergoes when struck by hand, stone, blade, cold, heat, hunger, thirst, insects, or snakes — so one wishes suffering beings into that place free of all suffering and of the very body that suffers. Sympathetic joy peaks at the sphere of infinite consciousness, wishing beings a happiness as boundless as consciousness pervading all. Equanimity peaks at the sphere of nothingness — which he calls "the last ground of the uncontaminated mind," the highest place the uncontaminated path can still be cultivated (unlike the peak of existence, whose perception is too faint for insight) — the equanimity of an arhat who meets pain, pleasure, and the neither alike with no defilement; one wishes all beings that arhat's equanimity.

He stresses these are noble practices "not shared with non-Buddhists": non-Buddhists cultivate the four immeasurables too, but cannot carry them this far, lacking the insight into no-self — which is why the sūtra pairs them with the seven awakening-factors. He raises the classical puzzle (the immeasurables are contaminated, the awakening-factors uncontaminated — how "together"?) and gives its resolution: not simultaneously but interleaved — the immeasurables make the mind pliant and fit and so draw forth the awakening-factors, which in turn draw the immeasurables, alternating; so that a see-er of the truths cultivating the immeasurables has the awakening-factors accompany them, and, as the Āgama promises, "I assure you the fruit of the non-returner" — not because loving-kindness itself cuts fetters, but because the merit and wisdom it gathers make the path that cuts them possible.

Master Cháng Bǎi explains that one-part cultivation attends to either the light-mark alone or the form-mark alone — which Kuiji maps to the first liberation (desire-realm form contemplated with a light-perception) and the second (external form contemplated); complete-cultivation attends to both, discerning light and seeing forms together, mapped to the third, "pure" liberation before its completion — a classical way of developing the divine eye. Cultivating this light-concentration, however, meets eleven obstacles (doubt and the rest — the four that obstruct the light-perception of reflection-wisdom and the seven that obstruct the light-perception of cultivation-wisdom, fully enumerated in the Ground of the Fruit of Cultivation).

He notes the treatise pins these difficulties to the two marks that sustain any concentration at all: the object-mark (the image the mind holds — here the light or the form) and the causal mark (the concentration-provisions — moderate eating, sense-restraint, precepts, wakeful practice, clear comprehension, the whole discipline of daily conduct that lets one sit at ease). Resting on both, one abides in the concentration; lose either, and one cannot — which is exactly where the eleven difficulties strike. They are now spelled out one by one.

Master Cháng Bǎi walks the eleven. Doubt: not clearly knowing the light-or-form mark, uncertainty dogs the contemplation. Non-attention: slack, lazy effort that fails to hold the object. Not wanting to attend to forms: turning away from the very object one should hold, like shutting one's eyes or turning one's back. Bodily heaviness: the fruit of failing to guard the senses, eat in measure, and keep the concentration-provisions. Dullness-and-sleep: too much or too little sleep clouds the mind, so forms cannot be seen, or only faintly. Excessive exertion: forcing effort against that dullness. Extreme sluggishness: the rebound — exhausted by over-forcing, the mind goes limp; his image is catching a quail, gripped too hard it is crushed and too loose it escapes, exactly as concentration is lost by effort too tense or too slack.

The last four turn on reactions to success. Elation: seeking only light, one gets light and form together — "hoping for one, getting two" — and leaps with joy like a man stumbling on two buried treasures, the excitement itself breaking the concentration. Great fear: suddenly seeing inauspicious forms — spectres — in every direction, terror seizes one like something lunging up on both sides. Assorted external thoughts: in activity or rest, stray worldly thoughts of sights, sounds, music, and letters — matters outside the Dharma and outside the practice — intrude and disturb. And self-exaltation: with a little pliancy won, one judges oneself superior and others inferior, the conceit a clinging to one's own attainment that is itself counted among the assorted thoughts. All eleven, Cháng Bǎi notes, are ways the object-mark or the causal mark slips, so that the concentration can no longer be sustained.

Master Cháng Bǎi completes the eleven with two more: much talk or prolonged discursive pondering, which tires the body until the mind cannot settle; and, once the concentration yields its light and reveals forms, abandoning the sustained inner cultivation to gaze outward at those forms in fascination — an over-scrutiny that pulls one out of the absorption. His concluding point is the treatise's own: every one of the eleven strikes at exactly the two marks that hold a concentration together — the object-mark (the image the mind holds) and the causal mark (the concentration-provisions of moderate eating, sense-restraint, precepts, wakeful practice, and clear comprehension). Where a difficulty takes hold, one or both marks is lost, and when they go, the concentration sinks with them.

Master Cháng Bǎi first sorts concentration by its accompanying feeling — joy accompanies the first and second dhyānas, bliss the third, and equanimity the fourth and above. Then he lays out the famous fourfold cultivation-of-concentration, sorted by its aim (from the Āgama, and matched in the Viniścaya to four kinds of practitioner pursuing four fruits). For a present pleasant abiding: cultivating the threshold and root dhyānas to reach the "four pleasant abidings in this very life" — the distinct happiness each dhyāna delivers (joy-and-bliss from seclusion, joy-and-bliss from concentration, sublime bliss, and pure equanimous stillness) — and to purify a root dhyāna still stained by relish, conceit, view, or doubt; he notes this is stressed over the "future" pleasant abiding because present ease is what even the unwise and the non-Buddhist believe in, and because a present dhyāna, when it arises, unfailingly delivers its happiness. For knowledge-and-vision: cultivating the light-perception on the path to the divine eye — "vision" being the eye that illumines and sees form-objects, "knowledge" being what it learns of the gods (their names, kinds, food, and lifespan, the classical eight ways a being's life is described).

For discerning wisdom: cultivating concentration on the path toward stream-entry — the sound thinking that in daily life knows each act and each feeling for what it is (knowing, while dressing, that one dresses; while walking, that one walks) — or to develop the four analytic knowledges of dharma, meaning, language, and eloquence. For exhausting the outflows: cultivating the vajra-like concentration of the final moment before arhatship, so hard and sharp it severs the innate afflictions at their root. The same absorption, Cháng Bǎi observes, serves radically different ends depending on the aim one brings to it — from a pleasant rest in this life all the way to the total exhaustion of every outflow.

Master Cháng Bǎi presents the five noble knowledges (五聖智) as the inward confirmations by which a noble one verifies, from within his own uncontaminated concentration, that it is the genuine kind. Self-nature knowledge: "this concentration is noble, undefiled, ungrasping" — noble because both wholesome and uncontaminated, undefiled naming its wholesome noble nature, ungrasping its uncontaminated one. Person knowledge: it is "not resorted to by ordinary beings," only by buddhas and noble disciples, "praised by the wise and never censured" — and here he draws a sharp contrast with worldly absorption, which the six-aspect contemplation must first praise as calm (to leave the lower ground) and then censure as coarse (to climb higher), whereas the noble concentration is praised at all times and never disparaged, because there is nothing coarse in it to leave behind.

Purity knowledge: it is "quiescent" (its target afflictions forever stilled), "subtle" (no relish even for its own ground's afflictions), "a secure path" (non-retrogressing), and "the mind's single course" (having reached the ground beyond applied and sustained thought). Fruit knowledge: it yields "present ease" (the pleasant abiding here and now) and "future blissful ripening" (drawing toward the bliss of nirvāṇa-without-remainder). Entering-and-exiting knowledge: one "mindfully enters and mindfully exits," firmly holding without forgetting the very marks by which the concentration is entered and left. Cháng Bǎi treats these five together as the noble practitioner's own reflective certainty — not another's testimony but his direct knowledge that his absorption is noble, pure, fruitful, and under his mindful command.

Master Cháng Bǎi introduces the noble five-limb concentration (聖五支三摩地) as the celebrated Āgama description in which the meditator's very body is drenched in the happiness of each dhyāna in turn — the four dhyānas forming four limbs, with a fifth "reviewing sign" completing the set. In the first limb, the first dhyāna's joy-and-bliss born of seclusion "drenches" the body (moistened by joy) and "pervadingly drenches" it (moistened by bliss). He draws out the precise gradation the treatise marks: at the earlier attention-stages the body is only "pervadingly gladdened," joy and bliss arising intermittently, neither lasting nor complete; at the consummation-of-means attention it is "wholly filled"; and at the fruit-of-the-consummation attention "not the least part of the body is left unfilled" — the finished absorption saturating the whole frame.

The soap-ball simile he maps point for point: the skilled bath-attendant (or his pupil) is the practitioner of contemplation; the copper, clay, or shell vessel is the teacher's instruction and admonition that produce the seclusion-born joy-and-bliss; the fine bath-powder is what conforms to the applied thought of renunciation; the water poured over it is the purifying path of applied thought; the kneaded ball of powder is the body itself; its being moist and greasy through and through, within and without, without a drop spilling, is joy and bliss uniting seamlessly through the body; and its holding together and not falling apart is the mind's undistracted one-pointedness. The same figure, he notes, will now be varied for each of the higher dhyānas' limbs.

Master Cháng Bǎi shows the same figure re-cast for each higher limb. For the second dhyāna, a mountain spring: the mountain is the thoughtless concentration, its peak the single-flavored conviction of the second dhyāna (past applied and sustained thought), the spring the "inner clarity" limb, and the water welling out sideways and upward the joy and bliss soaking the body without a gap. For the third dhyāna, lotuses growing soaked while their buds stay submerged beneath the water: the bliss-apart-from-joy pervades the body, and the submerged buds picture the absence of joy's leaping exultation — for the third dhyāna keeps bliss but has released joy.

For the fourth dhyāna, a man wrapped head to foot in a densely-woven white cloth: the pure equanimity-and-mindfulness that has transcended the lower grounds' three cosmic calamities and eight movements, and that is "bright-white" (wholesome, with no relish for its own afflictions), so pervading and firm that no scattering can invade it — enduring cold, heat, abuse, and bodily pain unmoved. He adds the treatise's further figure of the discerning elder for the accomplished fourth-dhyāna practitioner: thorough in all he does, free of heedlessness, deliberative in weighing and observing, and knowing every increase and decrease — his mind quick and clear.

Master Cháng Bǎi notes the fifth limb departs from the four-dhyāna pattern: it is the reviewing limb — the very reviewing-mark given back in fascicle 11 (the monk who, earnestly, thoroughly, and without distortion, takes up the object and examines it) — here meaning the close contemplation of the formations of the three times (the twelve links of dependent origination, and the aggregates as impermanent, suffering, empty, and selfless), and, further, examining even the act of examining itself (the after-mind reviewing the fore-mind).

He then draws out what makes the whole a "noble" concentration: the noble ones' one-pointedness of mind resting in the four dhyānas, joined to their careful investigation of what is established — that is, calm wedded to insight. And why five limbs: four are built on the four "pleasant abidings in this very life" (the distinct happiness of each dhyāna), and the fifth on two further grounds — the close contemplation of dependent origination and the severing of whatever fetters and bonds still remain (even a stream-enterer, having cut the view-path afflictions, still has the subtle cultivation-path afflictions to remove). So the noble five-limb concentration is a noble one, stream-enterer and above, resting in the four dhyānas, reviewing dependent origination, and cutting the residual afflictions — calm, insight, and severance in a single practice; the Śāriputra-Abhidharma promises that its accomplishment opens the six superknowledges at will.

Master Cháng Bǎi explains that the "noble right concentration with cause and equipment" (有因有具聖正三摩地) is the whole eightfold path seen from the standpoint of right concentration at its center, the other seven factors serving it in two roles. It is "noble" because wholesome and uncontaminated. Five factors are its cause (因) — right view, thought, speech, action, and livelihood — and three its equipment or support (具) — right view, effort, and mindfulness; right view is counted in both roles. "Cause" names these factors as what leads in sequence toward concentration; "equipment" names them as what directly assists it.

He traces the leading-sequence as a life's actual course into practice. Right view begins the moment one learns that there truly are arhats in the world who have walked the path of right conduct to its right attainment, and so conceives a deep wish for release. Right thought follows as the resolve to leave the cramp and confinement of household life. And right speech, right action, and right livelihood follow as the acts of going forth, undertaking the training of the precepts, and purifying one's means of living — the moral foundation that must be laid before concentration proper can arise. So the five are "cause" in the plain sense that they come first and carry one forward to the meditative center.

Master Cháng Bǎi explains the "equipment" sense — how right view, right effort, and right mindfulness directly assist the concentration. The five "cause" factors, once laid down, have not yet actually severed their opposites (wrong view and the rest); so, resting on those five wholesome factors and hearing the teaching from a teacher, one develops the right view of hearing-wisdom, then, by skillful investigation aimed at severing the opposites and gathering the path's provisions, reflection-wisdom, and then cultivation-wisdom. Matured through the three wisdoms, right view can now discern wrong from right in every factor — "this is wrong view, this is right view," on up through right livelihood.

Right effort is the diligence roused on that basis, both to sever the wrong factors and to bring the right ones to completion. Right mindfulness is what actually accomplishes the work — severing what is to be countered and gathering the countering factors to fullness — and because mindfulness is itself a limb of concentration, naming it already carries right concentration along with it. So the eightfold path, Cháng Bǎi stresses, is one integrated movement rather than eight separate items: right view leading, right effort and right mindfulness assisting, and all of them converging on right concentration at the center — the reason the Buddha called the seven the "cause and equipment" of the noble right concentration.

Master Cháng Bǎi marks two stages of "fulfillment." At the preparatory stage one is still in the act of casting off wrong view, wrong effort, and wrong mindfulness while bringing the right ones to fullness; at the fulfillment stage, when that severing-and-fulfilling is complete, the noble right concentration itself stands complete. He then folds the whole eightfold path into the three trainings. Wisdom leads (right view), so one first settles into the higher training in precepts — right speech, action, and livelihood. Then, on that moral base together with hearing the teaching and sound attention, the higher trainings in mind and in wisdom arise: right mindfulness is the higher training in mind (concentration), and right view with right effort the higher training in wisdom. So cultivating the noble right concentration is nothing other than fulfilling all three trainings at once — precepts, concentration, and wisdom perfected together, the eightfold path complete as a single integrated attainment.

Master Cháng Bǎi identifies the vajra-like concentration (金剛喻三摩地) as the concentration of a trainee's very last moment — the instant before arhatship, when the innate cultivation-path afflictions are severed at their root. He gathers the reasons the treatise gives for the name: it is the foremost and most excellent of concentrations, utterly firm, unassailable by any affliction (nothing "above" it can crush it), and able to crush every affliction beneath it. The simile is exact: as vajra — the diamond-hard "thunderbolt" — is so firm that no other gem can so much as scratch it, while it cuts through them all, so this concentration cannot be broken by any remaining affliction yet shatters them all. It is the decisive blow that ends the trainee's path and opens arhatship — the same vajra concentration named earlier (in fascicles 5 and 11) as the aspirant's final instant, here given its own dedicated treatment among the scriptures' concentrations.

Master Cháng Bǎi explains that the five direct-seeing attainments (五現見三摩鉢底) are cultivated only by one who has already seen the truths — hence "direct-seeing" — to counter the subtle cultivation-path afflictions by subduing them, severing them, and contemplating that severance. They proceed through a graded contemplation of one's own present body and mind. First the impurity of the internal body, to keep sexual craving from arising; then the external impurity, up through the bare skeleton, completing the survey of "all impurity"; then a deeper penetration of the dharma-nature, seeing that the body has just this nature and character by its very constitution.

Then the flow of consciousness: its ceaseless arising and perishing, contemplated coarsely as the twelve-link succession from one life-body to the next (formations conditioning consciousness), and finely as the momentary succession in which, across the passing hours, countless distinct mind-moments — now with craving, now free of it — arise and perish one after another. And finally the contemplation of severance, keyed to how far one has come: a trainee not yet free of desire still dwells in "both worlds" (this life and the next); one free of desire dwells "only in the other world" (no more desire-realm rebirth); and an arhat dwells in neither — no further rebirth at all. The five together are the noble one's direct seeing of his body's impurity, his mind's impermanence, and the exact reach of his own liberation.

Master Cháng Bǎi explains that the no-perception attainment (無想三摩鉢底) belongs to one who has left the third dhyāna's craving but not the fourth's; taking as its precondition the resolve to escape perception permanently, it stills the minds and mental factors. Its method: contemplating perception itself as a disease, a boil, an arrow, one enters the fourth dhyāna and cultivates the "turning-back-from-perception" attention — wearying of every perception that arises and holding the mind on the single thought that "only the perception-less is quiescent and subtle," until, leaving object after object, the mind falls quiet.

He draws the crucial distinction between cultivating it in this life and being reborn by it: cultivated here, one both enters and emerges; but one reborn by it into the No-Perception Heaven only enters — and the moment perception returns, one falls from that heaven. The tradition treats this as a meditative dead-end, mistaken by some non-Buddhists for liberation, since it merely suppresses perception without any insight into no-self; when its long lifespan runs out and perception resumes, rebirth in the lower realms follows. He notes the mastery- and totality-attainments named here were already treated under the eight masteries and ten totalities.

Master Cháng Bǎi explains that the cessation attainment (滅盡三摩鉢底, the cessation of perception and feeling — the eighth liberation) belongs to a noble one who has left the desire of the sphere of nothingness; taking as its precondition the resolve to abide temporarily in the perception-less, it stills the minds and mental factors entirely — the deepest of all attainments, reached only by non-returners and arhats. One enters it either by way of the fourth formless sphere (deeply wearying of its two remaining subtle minds until their objects are extinguished and the mind falls quiet) or directly by the "mark of cessation." Two things are indispensable: calm (the eight successive attainments, run through in order) and insight (the noble wisdom of no-self); lacking either, one cannot enter. This is exactly what sets it apart from the no-perception attainment — the cessation attainment is the noble path's own, requiring genuine insight, not mere suppression.

He lays out the order in which the three formations still. Going in, they cease in sequence: the speech-formation (applied-and-sustained thought, still active in the first dhyāna, which alone can produce speech) drops first; then, by the power of the second dhyāna and above, the body-formation (the in-and-out breath) and the mind-formation (perception and feeling) cease in turn. Coming out, they return in the reverse order. So the whole descent into cessation and re-ascent from it is a graded quieting and re-quickening of speech, breath, and mind.

Master Cháng Bǎi treats the two puzzles as classic. First: if all mind and mental factors are extinguished, how can scripture say "consciousness does not leave the body"? Because the material sense-faculties remain unspoiled and hold the storehouse-consciousness (ālayavijñāna), which is not extinguished and retains the seeds of the six active consciousnesses; so when the attainment ends, mind arises again from it. He flags this as one of the classic Yogācāra proofs for the storehouse-consciousness — something must persist through total cessation for life and mind to resume, and that is the ālaya. Second: with no thought "I shall enter" or "I shall exit," and no attention either going in or coming out, how does one enter and exit at all? By prior thorough cultivation: having cultivated the practices, states, and marks that carry one in and out exceedingly much, entering and emerging become spontaneous, requiring no deliberate thought in the moment.

On emerging, one touches three contacts by three objects. By the object that is — the unmoving contact: no self-conceit stirs the mind, no "this is I," no "I shall exist in future." By the object's object — the nothingness contact: there is no greed's "having," no hatred's, no delusion's — nothing is grasped as possessed. By the object of cessation — the signless contact: attending to no sign at all, one rests on the signless realm. Cháng Bǎi reads these three as the mark of a mind rising from the deepest cessation into a peace still free of self, of affliction, and of sign — the aftertaste of the cessation attainment carried back into ordinary awareness.

Master Cháng Bǎi reads this line as gathering up the whole of "gathering the essentials of the scriptures" so far — the four dhyānas, the eight liberations, and the many unifications (等持, samādhis) and attainments (等至, samāpattis) the fascicle has surveyed, from the eight masteries and ten totalities through the three doors to liberation, the immeasurables, the noble concentrations, the vajra-like concentration, and the no-perception and cessation attainments. He notes, however, that the fuller treatment of the unifications and attainments is not finished here: it carries on into the next fascicle. So this summary is a hinge, not a full stop — the Ground of Meditative Equipoise continues directly into fascicle 13.
