The Supramundane Path of the Four Noble Truths
Having laid out the mundane path in full in fascicle 33 — seven mental engagements climbing the four dhyānas and four formless absorptions to their summit — the treatise turns to the supramundane path. The very same seven engagements are applied instead to the four noble truths in their sixteen aspects, carrying a practitioner all the way to genuine liberation: stream-entry, once-return, non-return, and finally arhatship via vajra-like concentration. This fascicle then formally closes the entire Ground of the Hearer-Disciples — and, in the same breath, opens and completes the entire Ground of the Solitary Buddha.
1. The Supramundane Path Opens: Seven Engagements, Sixteen Aspects, Four Fruits
Having reached near-attainment concentration, a practitioner faced two roads: fascicle 33's mundane climb through the absorptions, or this fascicle's supramundane path — resting on the four noble truths instead, carried by the same seven mental engagements toward genuine liberation.
如是已辯往世間道。若樂往趣出世間道，應當依止四聖諦境，漸次生起七種作意。所謂最初了相作意，最後加行究竟果作意，乃至證得阿羅漢果。
The mundane path has now been fully explained. If one instead wishes to proceed toward the supramundane path, one should rest on the objects of the four noble truths, giving rise in sequence to seven kinds of mental engagement — from the very first, learning the mark, to the last, the fruit of the culmination of effort — up to the attainment of arhatship itself.
修瑜伽師，於四聖諦略標、廣辯增上教法，聽聞受持，或於作意已善修習，或得根本靜慮無色。由四種行了苦諦相……由四種行了集諦相……由四種行了滅諦相……由四種行了道諦相……如是名為了相作意。
A practitioner of yogic discipline, having listened to and upheld the excellent teaching on the four noble truths, both in brief summary and in detailed exposition — whether already well cultivated in the mental engagements, or already having attained the root dhyānas or formless absorptions — comes to know the truth of suffering through four aspects … the truth of origin through four aspects … the truth of cessation through four aspects … and the truth of the path through four aspects. This is called learning the mark.
Master Cháng Bǎi frames the two paths as sharing an identical seven-stage engine but pointed at entirely different destinations: the mundane path's engine climbs from one absorption to a subtler one above it, gaining ever-deeper stillness but never touching the underlying seeds of affliction; the supramundane path's identical engine — learning the mark, confident understanding, seclusion, gathering joy, examination, the culmination of effort, its fruit — is instead aimed at the four noble truths' sixteen aspects (four each for suffering, origin, cessation, and the path), and this time genuinely uproots affliction rather than merely suppressing it. He maps the four stages named at the very start of the fascicle — observation (觀察), penetration (通達), cultivation (修習), and culmination (究竟) — onto specific fruits: observation and confident understanding examine the sixteen aspects; penetration, reached at seclusion, delivers the first fruit, stream-entry; cultivation, through gathering joy and examination, severs the first eight (then all nine) grades of innate afflictions bound to the desire realm tied to self-view, craving, hatred, extreme views, pride, and ignorance, delivering the second and third fruits; and culmination, at the culmination of effort and its fruit, severs every remaining afflictive seed across all three realms — both the kind acquired through wrong teaching and the kind innate from birth — delivering arhatship, the fourth and final fruit. He also notes the twofold basis a practitioner may bring to this path: some arrive already accomplished in the mundane path's six later engagements ("already-practiced" yogins), others already resting on one of the root dhyānas or formless absorptions themselves ("already-transcended" yogins) — either foundation is sufficient to take up the four truths directly.
2. The Truth of Suffering's Ten Aspects, Compressed from Four
Suffering's four classical aspects — impermanence, suffering, emptiness, and no-self — are now expanded into ten sharper aspects, each one a distinct lens for actually seeing the same truth rather than simply reciting its name.
由十種行觀察苦諦，能隨悟入苦諦四行。何等為十？一、變異行，二、滅壞行，三、別離行，四、法性行，五、合會行，六、結縛行，七、不可愛行，八、不安隱行，九、無所得行，十、不自在行。如是十行，依證成道理能正觀察。
Through ten aspects one observes the truth of suffering, and is thereby able to enter into its four classical aspects. What are the ten? First, the aspect of change; second, of destruction; third, of separation; fourth, of inherent nature; fifth, of coming-together; sixth, of bondage; seventh, of the undesirable; eighth, of the unsettled; ninth, of nothing to be found; tenth, of powerlessness. One correctly observes by means of these ten aspects, according to the principle of valid proof.
Master Cháng Bǎi maps the ten aspects back onto the classical four with clean arithmetic: impermanence is unpacked into five aspects (change, destruction, separation, inherent nature, and coming-together), suffering itself into three (bondage, the undesirable, the unsettled), emptiness into one (nothing to be found — searching through the five aggregates for a self and finding none), and no-self into one (powerlessness — the aggregates a being depends on are entirely conditioned, unable to grant even so basic a wish as staying forever young). He stresses the treatise's own methodological order: valid observation always proceeds from scriptural authority first (至教量, the Buddha's own explicit teaching, accepted on trust before anything else) to direct observation (現見量, examining one's own present experience to confirm the same pattern) — the two working together rather than either alone, since scripture without confirming experience stays abstract, and experience without a scriptural frame can drift into idiosyncratic conclusions. The fascicle takes up each of the ten aspects one at a time in what follows, beginning with change and destruction together as impermanence's opening two aspects.
3. Section: Impermanence by Scriptural Authority — Beings Die and Are Reborn, Worlds Burn and Vanish
The very first aspect, change, is established first by the Buddha's own explicit word: both the world of living beings and the physical world they inhabit are impermanent, confirmed by the Buddha's own clairvoyant sight — a claim this fascicle's readers have already met, from the other direction, in fascicle 33's account of the three cosmic disasters.
此中且依至教量理。如世尊說：諸行無常……又此諸行略有二種。一、有情世間，二、器世間……世尊依彼有情世間，說如是言：苾芻當知！我以過人清淨天眼，觀諸有情死時、生時，廣說乃至身壞已後，當生善趣天世界中。
Here, resting first on the principle of scriptural authority: as the World-Honored One said, all conditioned things are impermanent … these conditioned things, in brief, are of two kinds — the world of sentient beings, and the physical world that contains them … regarding the world of sentient beings, the World-Honored One spoke thus: monks, you should know that with a pure heavenly eye surpassing that of ordinary humans, I observe beings at the time of their death and at the time of their rebirth — described in full down to the very break-up of the body, after which they are reborn into a fortunate destiny, a heavenly world.
又世尊言：苾芻當知！此器世間長時安住，過是已後，漸次乃至七日輪現，如七日經廣說。乃至所有大地、諸山、大海，及蘇迷盧大寶山王，乃至梵世諸器世界，皆被焚燒。災火滅後，灰燼不現，乃至餘影亦不可得。
And the World-Honored One further said: monks, you should know that this physical world abides for a very long span of time; but after that span has passed, in due sequence, as many as seven suns come to appear, as the *Discourse on the Seven Suns* explains in full — until every last thing, the great earth, the mountains, the great oceans, even Mount Sumeru itself, the king of great jeweled mountains, up to the entire physical world of the Brahmā realm, is consumed by fire. Once that conflagration has died down, not even ash remains visible, let alone any trace or shadow.
Master Cháng Bǎi treats this pairing as the treatise's chosen opening move precisely because it rests on nothing but the Buddha's own direct testimony, accepted before any personal verification: the sentient world's impermanence is attested by the Buddha's own perfected heavenly eye — categorically unlike an ordinary being's eye, or even a desire-realm god's merely inherited one, in that it sees without any obstruction of distance, light, or opacity — watching beings die and take rebirth exactly according to their karma, good conduct leading to a fortunate destiny's "fine form," unwholesome conduct to the "coarse form" of a bad one. The container world's impermanence is attested by the classical account of a world-age's end: a great eon of eighty intervening eons (twenty of formation, twenty of abiding, twenty of dissolution, twenty of voidness) ends when beings first migrate upward in sequence — hell-beings, then animals and hungry ghosts, then humans, until natural sages among humanity reach the second dhyāna and lead others there with them, emptying the world below the second dhyāna's heaven entirely — after which fire (reaching up to consume the first dhyāna's heaven), then in later cycles water (reaching the second) and wind (reaching the third), destroy everything below the fourth dhyāna, a scheme this fascicle's readers have already met in reverse in fascicle 33's account of why the fourth dhyāna alone is called "unmoved" and untouched by any of the three disasters. He adds a pastoral aside: apocalyptic panic about the end of the world is misplaced, since by the time any such world-ending fire actually arrives, the humans who might fear it have already long since migrated elsewhere. Both accounts together establish, purely on the Buddha's word, that literally nothing conditioned — not a being's own life, not the mountains, not Mount Sumeru itself — escapes this pattern of change; only afterward does the text move to confirming the same pattern through one's own direct observation.
4. Impermanence by Direct Observation: Fifteen Ordinary Changes in One's Own Body and Mind
Having established impermanence on the Buddha's word alone, the treatise now turns to confirming the identical truth through nothing but one's own daily observation — cataloguing fifteen ordinary kinds of bodily and mental change anyone can verify without taking anything on faith.
此中內事，有十五種所作變異……一、分位所作變異，二、顯色所作變異，三、形色所作變異，四、興衰所作變異，五、支節具不具所作變異，六、劬勞所作變異，七、他所損害所作變異，八、寒熱所作變異，九、威儀所作變異，十、觸對所作變異，十一、雜染所作變異，十二、疾病所作變異，十三、終歿所作變異，十四、青瘀等所作變異，十五、一切不現盡滅所作變異。
As for internal matters, there are fifteen kinds of change brought about … first, change of life-stage; second, of complexion; third, of bodily form; fourth, of rise and decline; fifth, of the limbs being whole or lacking; sixth, of fatigue; seventh, of harm done by others; eighth, of cold and heat; ninth, of posture; tenth, of contact; eleventh, of affliction; twelfth, of illness; thirteenth, of death itself; fourteenth, of the corpse's discoloration; fifteenth, of its final, total disappearance.
謂由觀見或自、或他，從少年位乃至老位，諸行相續前後差別，互不相似……如是且由現見增上作意力故，十五種行觀察內事種種變異無常之性。
One observes, in oneself or in another, that from youth all the way to old age, these continuously arising factors show, from earlier to later, differences unlike one another … thus, by the strengthened power of mental engagement resting on direct observation alone, one observes, through these fifteen aspects, the changing, impermanent nature of one's own internal matters.
Master Cháng Bǎi treats all fifteen as instances of one identical exercise, repeated with mechanical regularity in the source text itself: observe the same person or thing in two different states (young then old; radiant then haggard; whole-limbed then maimed; rested then exhausted; unharmed then injured; shivering then sweating; one posture held too long then shifted; pleasant sensation then painful; a calm mind then an afflicted one; healthy then gravely ill; alive then a corpse; a corpse fresh then discolored, bloated, and finally reduced to nothing visible at all) — then simply conclude, each time in the same formula, "these conditioned things are impermanent, because such prior-and-later change is directly observable." He singles out a few of the fifteen for their sharper illustrations rather than repeating the formula fifteen times: life-stage change is illustrated with Hè Zhīzhāng's Tang-dynasty poem on returning home gray-haired after a lifetime away, unrecognized by the local children, and with a folk verse — "let the young not mock the old, for age steals no one's youth, nor can the old take 'old age' away with them; it stays behind for the young who follow" — read as a call to urgency, since a mountain of gold at the end of life still cannot buy back the vigor needed to actually practice. Affliction-change gets Master Cháng Bǎi's fullest personal digression: he tells of a reincarnate lama measured by scientists at two hundred times an ordinary person's happiness, cited alongside a teacher's remark that "happiness is the preliminary condition for awakening" — grief being nearly impossible to think clearly through — and offers his own consolation for hard times: "adversity is precisely the seed of ease to come; where human warmth turns thin, the path draws near" — since it is exactly the people who criticize us, not the ones who flatter us, who show us the faults we cannot see in ourselves. Death's own aftermath (illness, dying, discoloration, final disappearance) is illustrated with a wry cautionary tale of an elderly hospital patient who had secretly won the lottery, and — teased by his doctor with the hypothetical of splitting the winnings — promptly died of the shock the instant he was asked to put the promise in writing: a warning, Master Cháng Bǎi notes dryly, meant to curb greed that instead demonstrates impermanence claiming the greedy man first.
5. Eight Causes Behind Every Change — Including the Mind Switching Objects Mid-Thought
Before detailing all fifteen kinds of change one by one, the treatise first names the eight causes that produce them — seven governing physical things, and one, distinctively, governing the non-physical: feelings, afflictions, and even which sense-consciousness is active from moment to moment.
一、積時貯畜，二、他所損害，三、受用虧損，四、時節變異，五、火所焚燒，六、水所漂爛，七、風所鼓燥，八、異緣會遇……一切有色及無色法所有變異，皆由如是八種因緣，除此更無若過若增。
First, decay through accumulated time; second, harm from others; third, wearing down through use; fourth, seasonal change; fifth, destruction by fire; sixth, ruin by water; seventh, drying by wind; eighth, encountering a different condition … every change of every thing possessing form, and every thing lacking form, arises from precisely these eight causes — beyond these there is nothing further, nothing in excess.
如是眼識正現在前，會遇聲、香、味、觸境等餘境餘緣，起異分識……又有貪者，會遇瞋緣，貪纏止息，發起瞋纏。如是有瞋、癡者，會遇異分煩惱生緣，當知亦爾。
Likewise, while eye-consciousness is presently active, if it encounters some other object or condition — a sound, a smell, a taste, a touch — a different, corresponding consciousness arises instead … and one who harbors craving, on encountering a condition that provokes anger, has their craving momentarily cease, and anger arise in its place. The same holds, one should know, for one who harbors anger or delusion encountering a condition provoking some other affliction.
Master Cháng Bǎi notes the first seven causes are exactly what common sense would expect for physical things — simple accumulated time (even a carefully stored, well-protected object degrades eventually, exactly as it would with careless handling, only more slowly), damage inflicted by others, ordinary wear from being used at all, the seasons turning green growth to withered yellow and back, and outright destruction by the three classical elements of catastrophe already met in fascicle 33's cosmology, fire, water, and wind. It is the eighth cause, "encountering a different condition," that does the most interesting work, since it alone accounts for change in things with no physical form at all — feelings, afflictions, even consciousness itself. A pleasant feeling shifts to an unpleasant one simply because its object changed, nothing more mysterious required; craving gives way to anger the instant a frustrating condition intervenes (the ordinary experience of covetousness curdling into rage the moment it is thwarted); and, in the sharpest illustration, eye-consciousness reading a page can be entirely displaced, mid-moment, by ear-consciousness the instant a sufficiently loud sound intervenes — the same underlying mind simply reassigning itself to whichever sense object currently commands the strongest condition. None of the eight causes, he stresses, are exotic: they are the plain mechanics of everyday change, made explicit here only so a practitioner can recognize impermanence operating in the most mundane possible circumstances, not merely in dramatic events like death.
6. The Same Impermanence Confirmed in the Surrounding World — Sixteen External Things
Having confirmed impermanence in one's own body and mind, the treatise turns the identical exercise outward: the same rise-and-decay pattern verified across sixteen categories of the surrounding world — land, gardens, mountains, water, one's trade, savings, food, transport, clothing, and more.
謂由觀見此地方所，先未造立道場、天寺、宅舍、市鄽、城牆等事；後見新造，善作善飾。復於餘時，見彼朽故，圮坼、零落、隤毀、穿闕，火所焚燒、水所漂蕩……如是一切外事諸行，前之六種是所攝受事，後之十種是身資具事。以要言之，當知其性皆是無常。何以故？形相轉變現可得故。
One observes that a given piece of land had, at first, no temple, shrine, dwelling, market, or city wall built upon it; later one sees it newly built, skillfully constructed and adorned; and later still, one sees it decayed, cracked, crumbled, fallen into ruin and gaping holes, consumed by fire or swept away by flood … of all these external matters, the first six pertain to what is possessed, and the latter ten to the requisites that sustain the body. In brief, one should know their nature is entirely impermanent — why? Because the transformation of their form and appearance is directly observable.
謂觀見彼，或衰、或盛，不久堅住。
One observes that they — men and women in their mutual attachments — now decline, now flourish, never abiding firmly for long.
Master Cháng Bǎi again treats all sixteen as the identical exercise repeated on a different object each time — land, gardens, mountains, water, one's trade, one's savings, food, transport, clothing, ornaments, music, incense and garlands, household goods, light itself, and finally relations between men and women — each observed new-then-decayed, full-then-empty, or thriving-then-collapsed, closing with the same formula each time. He draws out the richest of the sixteen for their poetry rather than repeating the pattern verbatim: gardens, with Chán master Lóngyá's verse on a tree blazing red with blossoms at dawn and standing bare by dusk, "if you compare flowers to human affairs, flowers and human affairs are one and the same"; one's trade and its rise-and-fall, with the wandering hermit-poet Hánshān's rhythmic lament on those who scurry after a livelihood their whole gray-haired life and never once take the plain, obvious road of practice instead, and *Dream of the Red Chamber*'s famous "All Good Things" song — everyone praises the immortal's path, yet no one can let go of fame, of gold, of a devoted spouse, of children, watching a wealthy man drop dead at fifty-eight with billions he can no longer use; savings, with a folk verse on dreaming of a vault heaped with gold, waking gleeful, only to find bare walls and an empty room; music, with a classical story of a king who wanted a musician's beautiful sound kept in his palace without the lute, the wood, or the trained player who produced it — his minister's answer, that such a thing is simply impossible, being itself the king's moment of awakening into emptiness; and men and women's bond, closed with Hànshān Déqīng's blunt verse that a lifetime's scheming leaves nothing behind but two empty hands, joy and sorrow endlessly quarreling, when the drum and gong of the whole performance finally fall silent and no one can say where home even was. He notes the treatise's own tidy summary: the first six external things (land, gardens, mountains, water, trade, savings) belong to what a being possesses; the remaining ten (food, transport, clothing, and the rest) are what sustains the body directly — together completing, with the fifteen internal changes already covered, a full sweep of ordinary experience in which impermanence is never once absent.
7. Beyond Direct Sight: Inferring the Momentary Arising-and-Ceasing Beneath Every Visible Change
Having confirmed impermanence's coarser, directly visible face in both body and world, the treatise now moves to a subtler claim that cannot be seen directly at all, only inferred — that every one of these visible changes is actually built from countless momentary arisings and ceasings, too fine for the eye to catch.
即由如是現見增上作意力故，觀察變異無常性已，彼諸色行雖復現有剎那生滅、滅壞無常，而微細故，非現所得。故依現見增上作意，應正比度。
Through this very power of mental engagement resting on direct observation, having already observed the impermanent nature of change, these very physical processes, although they genuinely possess momentary arising and ceasing — an impermanence of destruction — are, because so subtle, not something direct observation itself can grasp. So, resting still on that same power of mental engagement built on direct observation, one should correctly infer it instead.
謂彼諸行，要有剎那生滅滅壞，方可得有前後變異，非如是住得有變異……彼彼眾緣和合有故，如是如是諸行得生，生已不待滅壞因緣，自然滅壞。
These processes must have momentary arising, ceasing, and destruction — only then can there be any prior-and-later change to observe at all; they could not show such change while simply persisting unchanged … because this or that gathering of conditions comes together, these or those processes are able to arise; and having arisen, without needing to wait for any further destroying condition, they cease of themselves.
Master Cháng Bǎi treats this as a genuine escalation in subtlety rather than a restatement: everything observed so far — a body aging, a building crumbling, a garden withering — is impermanence coarse enough to be caught by the naked eye over stretches of time, but the treatise's own logic now demands something the eye can never catch directly. If a thing genuinely persisted unchanged moment to moment, no amount of waiting could ever produce the change eventually observed — change over a long span is only possible if the thing was never actually stationary even for one instant, arising and perishing so rapidly, so continuously, and each new instant so closely resembling the one before it, that ordinary perception mistakes the whole unbroken chain for a single, stable, enduring thing. This is proven not by seeing it directly, which is by definition impossible for something this fine, but by valid inference from the coarser fact already established: since visible change definitely happens, momentary arising-and-ceasing definitely underlies it, exactly as heat rising from a fire proves an unseen flame even before the flame itself comes into view. He adds the crucial corollary the treatise draws next: because a conditioned thing arises solely from the coming-together of causes and conditions, it never had any fixed nature of its own to begin with — and because it arises this way, it also ceases on its own the very next instant, needing no separate "destroying cause" to end it, since ceasing is simply what an unfixed, conditionally-arisen thing does by its very nature, the moment after it appears.
8. Section: Fire Never Truly Destroys Anything — It Only Changes What's There
A sharp philosophical correction follows: what looks like fire or water "destroying" something is never actually destruction at all, strictly speaking — it is simply this same moment-to-moment arising-and-ceasing producing a new, dissimilar appearance, since nothing conditioned was ever fixed enough to be annihilated in the first place.
如是所有變異因緣，能令諸行轉變生起。此是變異生起因緣，非是諸行滅壞因緣……由彼諸行，與世現見滅壞因緣俱滅壞已，後不相似生起可得，非彼一切全不生起。
All these causes and conditions of change are able to bring about the arising of a transformed process — this is a cause and condition for change to arise, not a cause and condition for a process's actual destruction … these processes, together with what the world directly observes as a "destroying" condition, cease together, yet a dissimilar successor is found to arise afterward — it is not the case that nothing whatsoever arises.
或有諸行既滅壞已，一切生起全不可得。如煎水等，最後一切皆悉銷盡；災火焚燒器世間已，都無灰燼，乃至餘影亦不可得。彼亦因緣後後展轉漸減盡故，最後一切都無所有。不由其火作如是事。
Or else, some processes, once destroyed, yield no further arising to be found at all — as when water is boiled away until every last trace is gone, or when the great conflagration burns the physical world until not even ash remains, let alone any trace or shadow. This too comes from cause and condition diminishing further and further in succession, until in the end nothing whatsoever is left — it is not that the fire itself simply performs this act of erasure.
Master Cháng Bǎi treats this as the treatise correcting a subtle but important misconception: ordinary, unreflective observation credits water, fire, and wind with "destroying" a house or a body, but the treatise insists this framing is imprecise. A burning house does not have its being annihilated by fire; rather, the house's own continuity — already ceasing and re-arising moment to moment, exactly as established above — simply takes on ash as its next, dissimilar successor state, with fire supplying the changing condition rather than a destroying one; wet a burning log and the fire itself goes out not because water possesses some power to annihilate flame, but because the log's own condition for sustaining fire (dryness) is now absent — the *Xiǎnyáng* treatise's verse is quoted directly: "it is not water, fire, or wind that destroys — since arising and ceasing occur together; once a corresponding condition has ceased, what remains is only a cause for further change." Only in the rarer case where the chain of successive changes bottoms out entirely — water boiled down to no residue at all, or a world-age's fire burning until not even ash or shadow remains — does the treatise allow that no further process is found to arise; and even there, it is careful to specify that this final disappearance is caused by conditions thinning out in succession, not by fire's own power to erase. He notes the deeper stake in getting this exactly right: if impermanence meant things simply popping into being from nothing and popping out of being into nothing, causality itself would break down; the treatise's insistence on ceaseless transformation, rather than creation and destruction from and into nothing, is what keeps karma's causal chain intact across every visible change, however dramatic.
9. Section: Refuting a Creator God — Why Present Differences Prove Only Past Karma
The same inferential reasoning now reaches beyond what can be directly seen at all — to past and future lives — and along the way delivers a compact philosophical refutation of the idea that a creator deity, rather than one's own prior actions, accounts for why beings differ so much from one another.
謂諸有情現有種種差別可得。或好形色、或惡形色，或上族姓、或下族姓……如是一切有情差別，定由作業有其差別，方可成立，非無作業。如是有情色類差別，定由先世善不善業造作增長種種品類。
One observes that beings display all manner of differences: fine form or coarse form, high lineage or low, wealth or poverty, large clan or small, long life or short, commanding speech or not, sharp faculties or dull … all such differences among beings can only be established as arising definitely from differences in past action — never from the absence of action. Such differences among the various kinds of beings definitely arise from wholesome or unwholesome karma accumulated and increased in former lives.
若說自在變化為因，能生諸行，此所生行為唯用彼自在為緣？為待餘緣，如是自在方能變化？若唯用彼自在為緣，是則諸行與彼自在俱應本有，何須更生。若言先有自在體性，然後行生，是則諸行不唯自在為緣生起。
If one claims that a sovereign deity, as sole cause, is able to produce these processes — are the processes thus produced brought about by that deity as the only condition, or must some further condition be present before that deity is even able to bring about the transformation? If the deity alone is the condition, then these processes and that deity ought both to have existed from the very beginning — what need is there for anything to be produced at all? And if one says the deity's own nature exists first, and only afterward do the processes arise, then the processes are plainly not produced by that deity as their sole condition after all.
Master Cháng Bǎi lays out the argument's structure plainly: beings visibly differ along seven axes (fine or coarse appearance, high or low lineage, rich or poor, large or small family, long or short life, commanding or unpersuasive speech, sharp or dull faculties), and since nothing arises without a cause, this observable variation must trace to some real difference in cause — and since it is not visible in this present life alone, the only remaining explanation is a difference in past karma, wholesome or unwholesome, accumulated before birth. He presents the treatise's refutation of a rival explanation — that a sovereign creator deity accounts for these differences instead — as a clean dilemma with no way through: either the deity alone is sufficient cause, in which case deity and creation should be equally eternal and nothing would ever need to be newly produced at all (undermining the very idea of "creation"); or some further condition beyond the deity is also required, in which case the deity was never the sole cause to begin with, and that further condition — not the deity — is doing the real explanatory work. The treatise presses the same dilemma one level deeper against the deity's own will or wish to create: is that will itself caused or uncaused? If caused by the deity alone, the same circular problem recurs; if caused by something further, then that further thing, not the deity, is the true cause — at which point, Master Cháng Bǎi notes, one may as well drop the deity from the explanation altogether and simply say that everything, one's own present circumstances included, traces back to real prior causes: one's own past actions, not anyone else's will.
10. Three Kinds of Strengthened Attention, and Separation as Impermanence's Third Aspect
The treatise closes its account of change and destruction by naming the three distinct kinds of strengthened mental engagement used throughout — trust in scripture, direct observation, and inference — then opens impermanence's third aspect, separation: the simple fact that no advantage, relationship, or possession stays attached to its holder forever.
如是略由三種增上作意力故，尋思觀察內外諸行是無常性。謂淨信增上作意力故，現見增上作意力故，比度增上作意力故。
Thus, in brief, by means of three kinds of strengthened mental engagement, one investigates and observes that internal and external processes alike are impermanent by nature — namely, mental engagement strengthened by pure trust, mental engagement strengthened by direct observation, and mental engagement strengthened by inference.
謂如有一，先為他主，非奴、非使，能自受用，能驅役他作諸事業；彼於後時退失主性，非奴使性，轉得他奴及所使性。於主性等，名為別離無常之性。
For instance, someone who was formerly another's master — neither a servant nor one commanded by others, able to enjoy things freely and to command others to carry out various tasks — later loses that condition of mastery, and, no longer free of servitude, instead comes to take on the very condition of being a servant, commanded by others. This losing of one's former condition of mastery and the like is called the impermanence of separation.
Master Cháng Bǎi treats the threefold summary as the treatise's own methodological signature, running through the entire investigation of the ten aspects: scriptural trust supplies the starting frame (the Buddha's own explicit word, accepted before verification), direct observation confirms the same pattern in one's immediate experience (the fifteen internal and sixteen external changes just catalogued), and inference reaches what neither trust nor direct sight alone can reach — the momentary arising-and-ceasing beneath all visible change, and now, by the same inferential method, differences reaching back into past lives no eye can see. With this framework named explicitly, the treatise turns to separation, impermanence's third aspect: a status, relationship, or possession that seemed stably attached to its holder in fact separates from them — illustrated with the reversal of a master into a servant, but understood to cover the whole range of ordinary loss: wealth separating from its owner, health from the body, a cherished relationship from both parties, status from whoever briefly held it. Where change and destruction established impermanence's motion (things shifting, and shifting all the way down to the momentary level), separation adds impermanence's sting: whatever a being has bound itself to holding onto is, sooner or later, simply not held any longer.
11. Section: Impermanence's Final Two Aspects — It Will Happen, and It Already Has
External separation (wealth seized by rulers, thieves, or disaster) closes the third aspect; the treatise then names impermanence's final two aspects — inherent nature, which reaches into the future to insist change is coming even where not yet seen, and coming-together, which confirms change, destruction, and separation are all already present at once, right now.
依外別離無常性者，謂現前有資生財寶，先未變異，未為別離無常滅壞；後時為王、盜賊、非愛，及共財等之所劫奪，或由惡作加行失壞，或方便求而不能得。
As for the impermanence of external separation: one presently has requisite wealth, not yet changed, not yet destroyed by the impermanence of separation; but later it is seized by rulers, by thieves, by an enemy, or by a co-owner, or lost through some past misdeed now ripening, or, though diligently sought by every means, simply cannot be obtained.
謂即所有變異無常、滅壞無常、別離無常，於現在世猶未合會，於未來世當有法性……謂即如是變異無常、滅壞無常、別離無常，於現在世合會現前。如實通達如是諸行，於現在世現前合會。
As for inherent nature: the very impermanence of change, of destruction, and of separation, though not yet come together in the present, will definitely occur in the future by their inherent nature … as for coming-together: this very impermanence of change, of destruction, and of separation, is already come together and present right now in the present. One correctly penetrates that these processes are, in the present, already come together before one.
Master Cháng Bǎi treats external separation as simply extending the internal case (a master losing mastery) outward to wealth itself — seized by taxation, theft, a rival claimant, a past misdeed finally ripening, or a once-profitable venture that circumstances have quietly made worthless (he offers the modern example of photographic film, once lucrative, now unsellable once digital cameras took over). He then explains why the treatise needs two further, seemingly redundant aspects beyond change, destruction, and separation: inherent nature closes off the natural evasion that impermanence might somehow be avoidable if it simply hasn't shown up yet — even where a person or thing has not yet visibly changed, decayed, or been separated from something, the treatise insists this is only a matter of timing, since it is these three processes' very nature to occur, sooner or later, without exception; watching someone else die, one should feel "the heat of fire" at the certainty that this outcome awaits oneself too. Coming-together then closes the opposite evasion — that impermanence is only ever a future abstraction — by pointing out that change, destruction, and separation are not sequential events happening one at a time but are, in fact, already occurring together, right now, in this very moment, for anyone paying close enough attention. With inherent nature and coming-together, impermanence's five aspects (change, destruction, separation, inherent nature, coming-together) are now complete, closing suffering's first classical aspect in full.
12. Section: Suffering's Own Three Aspects — Bondage, the Undesirable, the Unsettled
With impermanence fully established, the treatise moves to suffering's own three sharper aspects: bondage (affliction itself binds a being to suffering), the undesirable (the plain unwantedness of birth, aging, sickness, and death), and the unsettled (even neutral feeling secretly carries suffering's seeds).
作是思惟：如是諸行皆是無常；是無常故，決定應是有生法性；如是諸行既是生法，即有生苦；既有生苦，當知亦有老病死苦、怨憎會苦、愛別離苦、求不得苦。如是且由不可愛行趣入苦行。
One reflects thus: these processes are all impermanent; being impermanent, they must necessarily possess the nature of arising; being subject to arising, there is thereby the suffering of birth; and given the suffering of birth, one should know there is also the suffering of aging, sickness, and death, the suffering of meeting the disliked, the suffering of separation from the loved, and the suffering of not obtaining what is sought. Thus, by means of the aspect of the undesirable, one enters into the aspect of suffering.
以於愛等結處生愛等結，於貪等縛處生貪等縛，便能招集生老病死愁悲憂苦，一切擾惱純大苦蘊……有漏、有取、順非苦樂一切諸蘊，麤重俱行苦、樂種子之所隨逐，苦苦、壞苦不解脫故，一切皆是無常滅法。
Because, wherever craving and its fellow fetters find their basis, craving and its fellows arise, and wherever greed and its fellow bonds find their basis, greed and its fellows arise, one thereby comes to accumulate the suffering of birth, aging, sickness, death, sorrow, grief, and distress — a whole mass of pure, unrelieved suffering … every aggregate that is contaminated, grasped at, and conducive to neutral feeling is pursued by the underlying seeds of suffering and of pleasure alike, still bound together with them — for this reason, all of it is an impermanent, perishing phenomenon.
Master Cháng Bǎi shows how suffering's three aspects map cleanly onto the three classical kinds of suffering: the undesirable aspect is simply the eight sufferings of ordinary existence — birth entailing every suffering that follows from it, since impermanence guarantees whatever arises will also age, sicken, die, meet what it dislikes, lose what it loves, and fail to get what it wants — corresponding to suffering-as-pain (苦苦), the suffering built into an outright painful sensation. Bondage traces every affliction back to two named lists — nine "fetters" (craving, hatred, pride, ignorance, views, grasping, doubt, envy, and stinginess) and three "bonds" (greed, hatred, delusion) — which the *Compendium of Topics* analyzes as binding a being to suffering through five distinct mechanisms: binding one to the object craved, binding one affliction to trigger further afflictions (craving frustrated becoming hatred, hatred breeding envy), binding one to the wrongdoing an affliction provokes, binding one into an entrenched habitual pattern through repetition, and binding one to future rebirth in the six realms — corresponding to suffering-as-decay (壞苦), pleasure itself souring the moment craving for it takes hold. The unsettled aspect is the subtlest: even neutral feeling, seemingly free of both pain and pleasure — the equanimous feeling a practitioner rests in from the fourth dhyāna upward — still carries the dormant seeds of both suffering and pleasure, unresolved and merely quiet rather than actually uprooted, corresponding to suffering-as-conditioning (行苦), the bare fact of being a conditioned aggregate at all; the treatise is explicit that even a purely neutral sensation is, strictly, "an impermanent, perishing phenomenon" no different in kind from an outright painful one, only quieter about it. Master Cháng Bǎi stresses this third kind is precisely what most easily escapes ordinary notice — pain announces itself and pleasure invites clinging, but equanimity feels like nothing at all, which is exactly why unwary practitioners can mistake its stillness for freedom rather than recognizing it as suffering's most patient disguise.
13. Section: Emptiness and No-Self Complete the Truth of Suffering's Ten Aspects
The final two aspects close the set: emptiness, finding no fixed self anywhere among the five aggregates, and no-self, recognizing that whatever arises from causes and conditions can never truly govern itself. Together with the eight aspects already covered, all ten now map cleanly back onto the classical four.
如是唯有諸蘊可得。於諸蘊中，無有常恆、堅住、主宰，或說為我，或說有情……由是諸行皆悉是空，無有我故……所有諸行與其自相，及無常相、苦相相應。彼亦一切從緣生故，不得自在；不自在故，皆非是我。
Thus, only the aggregates themselves are to be found. Within the aggregates there is nothing permanent, stable, or governing that could be called a self or a being … for this reason, these processes are all empty, since there is no self within them … all these processes are joined with their own particular characteristics, and with the characteristics of impermanence and suffering. Since every one of them arises from conditions, none is self-governing; and being ungoverned, none of them is a self.
謂無常行五行所攝……苦行三行所攝……空行一行所攝。謂無所得行……無我行一行所攝。謂不自在行……彼由十行悟入四行。
Impermanence is subsumed under five aspects … suffering is subsumed under three aspects … emptiness is subsumed under a single aspect — nothing to be found … no-self is subsumed under a single aspect — powerlessness … through these ten aspects, one thereby enters the four.
Master Cháng Bǎi treats emptiness as the direct product of searching the five aggregates for a permanent, stable, self-governing owner and finding literally nothing there — no self who is born, ages, sickens, or dies, no fixed agent who acts and no fixed recipient who receives the results, only aggregates themselves, provisionally labeled "self" or "being" the way two identical chairs might be labeled "chair one" and "chair two" for convenience, with neither label picking out anything that actually governs its own chair. No-self then supplies the reason emptiness holds: everything arising from causes and conditions is, by that very fact, unable to govern itself — wishing a body to stay well does not keep it well, wishing a mind to stay calm does not keep it calm the moment circumstance provokes it — and whatever cannot govern itself was never a self to begin with. With these final two aspects in place, the treatise closes its whole ten-aspect analysis by mapping cleanly back onto the classical four: impermanence absorbs five aspects (change, destruction, separation, inherent nature, coming-together), suffering absorbs three (bondage, the undesirable, the unsettled), emptiness absorbs one (nothing to be found), and no-self absorbs one (powerlessness) — ten doors opening onto the same four rooms, each door simply catching a detail the others might have let slip past unnoticed. The truth of suffering itself now stands fully established; the treatise turns next to asking where suffering actually comes from.
14. Section: The Truth of Origin — Craving as Cause, Accumulation, Arising, and Condition
Having established that suffering is real, the treatise turns to its source: craving, examined through four aspects — cause, accumulation, arising, and condition — with three successive interpretive layers unpacking exactly how a single craving produces an entire chain of future suffering.
謂了知愛能引苦故，說名為因。既引苦已，復能招集令其生故，說名為集。既生苦已，令彼起故，說名為起。復於當來諸苦種子能攝受故，次第招引諸苦集故，說名為緣。
Knowing that craving is able to bring about suffering, it is called the cause. Having brought suffering about, craving is further able to accumulate it, causing it to arise, so it is called accumulation. Having given rise to suffering, craving causes it to actually manifest, so it is called arising. And since craving is further able to take hold of future seeds of suffering, drawing them in sequence into an accumulating mass of suffering, it is called condition.
復有差別。謂了知愛是取因故，復能招集即以其取為因有故，復能生起有為上首當來生故，又能引發以生為緣老、病、死等諸苦法故。隨其所應，當知說名因、集、起、緣。
There is a further distinction. Knowing that craving is the cause of grasping, it is called cause; being further able to accumulate the state of existence that has grasping as its cause, it is called accumulation; being further able to give rise to the future rebirth headed by that state of existence, it is called arising; and being further able to bring about the various sufferings of aging, sickness, and death that take rebirth as their condition, it is called condition — each, as appropriate, understood by this same fourfold naming.
Master Cháng Bǎi walks through why craving alone is singled out as suffering's root, even though the eightfold path names it as only one of many afflictions: craving is what plants a suffering-producing seed in the storehouse consciousness in the first place (cause); craving is what keeps watering and strengthening that already-planted seed through repetition (accumulation); craving is what actually forces the seed to sprout into a new rebirth, most sharply visible in the fierce self-attachment (自體愛) that seizes a dying person at the very moment their old body fails and a new one must be found (arising); and craving is what keeps drawing future suffering onward in an unbroken chain, since the newly reborn being will crave again, and again produce more suffering to be craved against (condition). He passes along the venerable Miàojìng's gloss mapping this same four-part scheme directly onto the twelve links of dependent origination: craving-as-cause corresponds to ignorance conditioning volitional formations (the deepest root); craving-as-accumulation corresponds to feeling conditioning craving and craving conditioning grasping (the watering that strengthens what ignorance first planted); craving-as-arising corresponds to grasping conditioning becoming, becoming conditioning birth (the moment the new rebirth actually locks in); and craving-as-condition corresponds to birth conditioning aging-and-death (suffering's endless downstream cascade). The passage's second interpretive layer simply re-walks the same four terms one notch further along the twelve links themselves — craving as cause of grasping, grasping's resulting existence as what craving accumulates, that existence's resulting rebirth as what craving gives rise to, and rebirth's resulting aging, sickness, and death as what craving conditions — the same underlying claim, reframed to track the chain link by explicit link rather than by the four more abstract terms alone.
15. A Third Lens on Craving, and the Truth of Origin Complete
A third interpretive layer distinguishes dormant craving-seeds from three kinds of actually manifesting craving, closing the truth of origin's four aspects with a precise map of exactly how self-attachment cascades into rebirth's entire chain.
謂正了知煩惱隨眠附屬所依，愛隨眠等是當來世後有生因……謂後有愛能招引故，即是其集；此後有愛，復能發起喜貪俱行愛；此喜貪俱行愛，復與多種彼彼喜愛為緣。
One correctly knows that the dormant affliction, attached to its underlying basis, is what serves as craving-seed and the like — the cause of a future existence yet to come … because this craving for a future existence is able to draw it forth, this itself is the accumulation; this craving for a future existence is further able to give rise to a joy-and-greed-linked craving; and this joy-and-greed-linked craving is further a condition for manifold instances of craving toward this and that pleasant thing.
Master Cháng Bǎi glosses the third layer's four terms with the *Discourse Distinguishing the Excellent Gateway to Dependent Origination*'s own precise definitions: plain craving is attachment to one's present existence; craving-for-future-existence is the longing for a future body, seizing a dying person exactly at the moment the old body fails; joy-and-greed-linked craving is deep relish in whatever pleasant object is currently possessed or about to be; and craving-toward-this-and-that is the restless pursuit of pleasant objects not yet possessed at all. He notes how neatly this covers the whole of ordinary desire: what is already held is clung to, and what is not yet held is chased — a completeness that makes the sea of craving, and hence the sea of suffering, genuinely boundless. With this third lens in place, the treatise closes the truth of origin's four-aspect analysis (cause, accumulation, arising, condition) having now examined craving from three angles: as suffering's cause pure and simple, as one link among the twelve of dependent origination, and as craving's own internal fourfold structure — three complementary views of a single underlying claim, that suffering's entire arising traces back to nothing more exotic than desire clinging to what is fleeting.
16. Section: The Truth of Cessation — Extinguished, Still, Sublime, and Free
Having traced suffering to its root in craving, the treatise now describes what it actually looks like for that root to be pulled out entirely — nirvāṇa itself, unpacked into four aspects that build from mere extinction to something the treatise calls, without qualification, the finest thing there is.
復正覺了如是集諦無餘息滅，故名為滅……一切苦諦無餘寂靜，故名為靜……即此滅、靜，是第一故、是最勝故、是無上故，說名為妙……是常住故、永出離故，說名為離。
One further correctly comes to know that this very truth of origin is extinguished without remainder — this is called extinction … every aspect of the truth of suffering is stilled without remainder — this is called stillness … this very extinction and stillness is foremost, is most excellent, is unsurpassed — this is called sublime … it is permanent, and a final departure — this is called freedom.
Master Cháng Bǎi walks through each of the four terms as a progressively deeper description of the same single attainment. Extinction names the removal of the cause: every affliction the path of seeing and the path of cultivation are meant to sever — the "lower fetters" binding one to the desire realm (self-view, attachment to rules and rituals, doubt, and the desire realm's own greed and hatred — the first three severed at stream-entry, the greed and hatred at non-return) and the "upper fetters" binding one to form and formless existence (subtle craving for those realms, restlessness, pride, and ignorance, only fully severed at arhatship) — gone without a single seed remaining. Stillness names the removal of the resulting suffering: with no further craving to fuel it, the aggregates simply cease on schedule, one moment's five aggregates ending and no next moment's arising to replace them — this is the difference between an arhat's "nirvāṇa with residue" (still embodied, the body's ordinary aches persisting until natural death) and "nirvāṇa without residue" (no body at all remaining to ache). Sublime and freedom then describe what this extinction-plus-stillness actually amounts to, cross-referenced by Master Cháng Bǎi to the *Discourse*'s own three-part gloss — sublime because it is blameless, pure, and truly blissful (the ultimate bliss beyond ordinary pleasure and pain alike), and free because it is permanent and a final departure from the three realms, never again subject to what was just extinguished. He stresses that this is presented without hedging as literally the finest state achievable — not one attainment among many comparable ones, but the single point every other aspect of practice has been building toward.
17. Section: The Truth of the Path — All Sixteen Aspects of the Four Truths Now Complete
The sixteenth and final aspect describes the path itself — the actual method, thirty-seven factors deep, that genuinely leads from suffering's cause to its cessation — closing the entire sixteen-aspect analysis of the four noble truths that learning the mark has been building toward this whole time.
復正覺了真對治道，於所知境能通尋求義故，能實尋求義故，由於四門隨轉義故，一向能趣涅槃義故，所以說名道、如、行、出。
One further correctly comes to know the genuine counteracting path: because, with respect to the objects to be known, it is able to lead through to what is sought, it is called the path; because it is able to genuinely reach what is sought, it is called the fitting way; because it operates by circulating through these four gateways, it is called the practice; and because it leads uniformly toward nirvāṇa, it is called the exit.
Master Cháng Bǎi glosses each of the path's four names as one facet of the same thirty-seven factors of enlightenment — the four foundations of mindfulness through the eightfold path, graded by depth of practice into the four right efforts, four bases of power, five faculties, five powers, seven factors of awakening, and the eightfold path itself. "The path" names its basic function: a genuine counteracting method actually leads somewhere, from suffering's cause through to cessation, unlike a false path that only looks like progress. "The fitting way" names its accuracy: when actually accomplished, it delivers a truthful correspondence with reality itself (真如), not merely a comforting belief. "The practice" names its method: cycling continuously through observation of all four truths together at once — Master Cháng Bǎi cites the *Discourse on the Noble Path of Dependent Origination*'s own worked example, tracing aging-and-death back through birth, existence, grasping, craving, feeling, contact, the six sense-bases, name-and-form, consciousness, and volitional formations, asking of each link in turn: has it been seen as suffering? has its origin been seen? has its cessation been seen? has the path to its cessation been seen? — a single four-truth investigation applied link by link down the entire chain of dependent origination, not limited to any one link alone. "The exit" names its destination: unlike every other kind of striving in the three realms, which merely shifts one's position within saṃsāra, this method alone leads uniformly out of it. With this, all sixteen aspects across all four truths — suffering's ten, origin's four (now three interpretive layers deep), cessation's four, and the path's four — stand complete for the aggregates one can presently, directly observe.
18. Section: Extending the Same Sixteen Aspects to What Cannot Be Directly Seen — Direct Knowledge and Analogical Knowledge
A practitioner reasoning from a human body can directly observe only the desire realm's own aggregates. The treatise now extends the identical sixteen-aspect analysis, by inference alone, to the form and formless realms no living human can currently see — introducing the classical distinction between direct knowledge and analogical knowledge that will structure the entire path of seeing ahead.
彼既如是於其自內現見諸蘊，依諸諦理，無倒尋思正觀察已；復於所餘不同分界不現見蘊，比度觀察……彼所有滅，皆永寂靜，常住安樂。彼所有道，皆能永斷，究竟出離。
Having thus, with respect to one's own directly observed aggregates, correctly and without distortion investigated and observed according to the principle of the truths, one then, with respect to the remaining aggregates of a different, not-directly-observed realm, observes by inference instead … their cessation is entirely and permanently still, abiding in lasting bliss; and their path is entirely able to bring about permanent severance, ultimate departure.
當知此中，若於現見諸蘊諦智，若於所餘不同分界不現見境比度諦智，即是能生法智、類智種子依處。
One should know that, in this regard, the truth-wisdom concerning directly observed aggregates, and the truth-wisdom arrived at by inference concerning the remaining, not-directly-observed realm, are respectively the basis giving rise to the seeds of direct knowledge and of analogical knowledge.
Master Cháng Bǎi frames this extension as necessary rather than optional: a practitioner seeking release from the entire three realms cannot stop at understanding the desire realm alone, since lingering attachment to the form or formless realms' subtler pleasures — the very absorptions detailed at such length in fascicle 33 — would leave the path incomplete; the same sixteen aspects (impermanence through the exit) must be established for the form and formless realms too, even though no human being can currently observe those realms' aggregates directly. The method is inference from the already-established case: since the desire realm's aggregates were shown, through direct observation, to be impermanent, suffering, empty, and selfless, arising from craving and ending in cessation through the path, the same must hold for the higher realms' aggregates as well, since nothing about them exempts them from being conditioned, arisen from causes, and therefore subject to the identical fourfold analysis — the same suffering, the same craving, the same cessation, the same path, only differing in which specific afflictions and pleasures are involved. This yields the technical distinction the whole path of seeing will depend on: "direct knowledge" (法智), wisdom grounded in what is presently and commonly observable (the desire realm's own aggregates), and "analogical knowledge" (類智), wisdom of the identical structure extended by valid inference to what cannot presently be seen at all (the form and formless realms). Master Miàojìng's account traces the seven preparatory stages a practitioner passes through to reach this point — the five stilling contemplations, particular and then unified mindfulness of the four foundations, and finally the four stages of heat, summit, forbearance, and supreme-in-the-world — the last of these delivering, in a single moment, entry into stream-entry itself. Master Cháng Bǎi notes the elegant symmetry: direct knowledge and analogical knowledge are not two different truths, only the same one truth grasped first where it can be seen and then, by the same reasoning, wherever it cannot.
19. Section: Wanting Liberation and Still Flinching From It — Cessation's Confident Understanding
Confident understanding now turns to cessation's own four aspects — but the treatise is unusually candid here: even a sincere practitioner who genuinely wants nirvāṇa can find themselves recoiling from it, still bound by a lifetime's habituation to sensory experience.
即於如是諸有、諸趣死生法中，以無願行、無所依行、深厭逆行發起勝解，精勤修習勝解作意……彼於長夜，其心愛樂世間色聲香味觸等……由是因緣，雖於涅槃深心願樂，而復於彼不能趣入、不能證淨、不能安住、不能勝解，其心退轉。
Precisely within these states of existence, these destinies of death and rebirth, one gives rise to confident understanding through wishless conduct, conduct without reliance, and conduct of deep aversion, diligently cultivating this confident-understanding engagement … through the long night of time, the mind has taken delight in the world's forms, sounds, scents, tastes, and textures … for this reason, though one sincerely wishes for nirvāṇa, one is still unable to actually enter it, unable to attain purified conviction in it, unable to abide in it, unable to gain confident understanding of it — the mind keeps reverting back.
於寂靜界未能深心生希仰故，有疑慮故，其心數數厭離、驚怖……謂於爾時，生如是念：我我今者何所在耶？是名驚怖應知。
Because one is not yet able to deeply admire and long for the realm of stillness, and because doubt remains, the mind again and again withdraws in aversion and alarm … at such a time, one gives rise to a thought like this: where, then, am I — my self — right now? This is what is called alarm.
Master Cháng Bǎi treats this passage as the treatise's most psychologically honest moment so far. The three conducts leading toward cessation's confident understanding are named precisely: wishless conduct sees the emptiness and lack of self in the five aggregates and simply stops wishing for a next existence; conduct without reliance sees that no self can be found to lean on in the first place; and deep aversion turns fully away from what impermanence and suffering have already exposed. Yet the treatise immediately and candidly names the resistance this same practitioner still runs into: a mind steeped since beginningless time in the pleasures of form, sound, scent, taste, and touch cannot simply decide, on the strength of correct doctrine alone, to stop wanting them — genuinely wishing for nirvāṇa in principle and yet, in the actual moment of approach, still flinching from a state with none of the sensory richness the mind has always known. Master Cháng Bǎi is candid about the underlying doubt this exposes: faith built only on comforting belief, never tested against genuine investigation into reality, tends to collapse exactly when aging, sickness, and death arrive to test it, whereas faith grounded in actual wisdom holds. He glosses the "alarm" described here concretely: in meditation, a sense that the body has disappeared, even that the mind itself seems to have dropped away, can trigger a genuinely disorienting fear — "where am I?" — precisely the fear of a self one has never examined closely enough to know isn't there to lose in the first place.
20. Section: Spiritual Pride — The Subtlest Obstacle, Right at the Threshold of Insight
Just as a practitioner nears genuine breakthrough, a peculiarly stubborn obstacle appears: not craving for ordinary pleasure, but pride in one's own practice itself — "I am the one observing suffering as suffering" — a self-congratulation so habitual it arises unbidden and blocks the very insight it seems to accompany.
以彼猶有能障現觀麤品我慢隨入作意，間、無間轉……作是思惟：我於生死曾久流轉……我能觀苦真實是苦，我能觀集真實是集，我能觀滅真實是滅，我能觀道真實是道……如是諸法是我所有。
Because there is still a coarse-grade conceit obstructing direct realization, intruding into engagement now with a gap, now without one … one thinks thus: I have long circled through birth and death … I am able to observe suffering as truly suffering, I am able to observe origin as truly origin, I am able to observe cessation as truly cessation, I am able to observe the path as truly the path … all these things belong to me.
彼既了知如是我慢是障礙已，便能速疾以慧通達……彼既如是以心緣心，專精無替，便能令彼隨入作意障礙現觀麤品我慢，無容得生。
Having recognized that this very conceit is an obstruction, one is quickly able to penetrate it with wisdom … having thus taken mind itself as the object observed by mind, with focused, unrelenting attention, one is able to prevent this coarse-grade conceit, which obstructs direct realization by intruding into engagement, from arising at all.
Master Cháng Bǎi treats this as an unusually frank warning aimed squarely at serious practitioners rather than beginners — precisely because it only shows up once real progress has been made. Having genuinely investigated the four truths, generated real revulsion toward saṃsāra, and sincerely longed for nirvāṇa, exactly this accomplishment quietly curdles into its own subtle pride: "I have long suffered through saṃsāra, I alone now correctly see suffering as suffering, origin as origin" — a coarse-grade conceit (麤品我慢) so deeply habituated by beginningless self-attachment that it arises automatically, unbidden, without the practitioner even noticing it has appeared, and which quietly reinstates exactly the self the practitioner thought they had already seen through. He notes wryly that this pattern is visible even outside formal practice — a newly ordained monastic, eager to serve everyone humbly, can over years curdle into the "old hand" who considers such service beneath them — and that spiritual practice is no exception: the very sense of "my accomplishment, my insight" is itself the last redoubt of self-view, precisely because it borrows the language of genuine practice to disguise itself. The remedy the treatise gives is exact and practical: rather than fighting the conceit as an external enemy, turn the very same investigating mind that has been observing the four truths back onto itself — "mind observing mind" (以心緣心) — watching one's own present thought with the immediately preceding thought as its object, so that the habitual conceit, the instant it stirs, is caught watching itself, and simply has no room left to complete its usual unnoticed arising.
21. The Path's Confident Understanding — Nothing Exists Outside the Mind That Perceives It
Confident understanding closes with the path's own four aspects, and along the way delivers a compact statement of a properly Yogâcāra insight — that what appears to be an external object is never actually apart from the mind perceiving it — illustrated with a pair of matched classical similes about the deer, the bird, and the sage.
棄捨任運隨轉作意，制伏一切外所知境，趣入作意。
One relinquishes the habitually arising engagement, subdues every externally apprehended object, and enters into genuine engagement.
隨作意行，專精無間觀察聖諦；隨所生起心謝滅時，無間生心，作意觀察，方便流注，無有間斷。
Following this engagement, one observes the noble truths with focused, unbroken attention; the instant each arising thought passes away, without any gap a new thought arises to continue the observation — a skillful, flowing continuity, without interruption.
Master Cháng Bǎi identifies "subduing every externally apprehended object" as the treatise quietly stating a core Yogâcāra claim: what a meditator experiences as an object during concentration is never something existing apart from the perceiving mind, only the mind's own manifestation, appearing to itself as if external — habitual clinging to objects as mind-independent is precisely what this confident understanding subdues. He passes along Venerable Miàojìng's observation that this teaching is not a purely Mahāyāna innovation, citing two nearly identical similes from significantly earlier sources: the *Discourse of Similes*' "the deer belongs to the wilds, the bird to open sky, the mind to discrimination, the true person to cessation," and the *Great Commentary*'s matching "the beast returns to the forest, the bird to the sky, the noble one to nirvāṇa, phenomena to discrimination" — both placing "mind" or "phenomena" in exactly the same structural slot as "deer" and "bird," each returning to its own proper domain: a deer belongs in the wild, a bird in open sky, and every apprehended phenomenon belongs, ultimately, only within discriminating mind itself. He then describes the practical technique this insight makes possible: since the conceited thought identified in the previous section only ever obstructs by intruding with a gap in the stream of engagement, filling that stream with unbroken observation — one thought's passing immediately met by the next thought's arising, with no interval left for anything else to intrude — starves precisely the subtle self-conceit of the opening it needs, a technique of sheer continuity rather than direct confrontation.
22. Section: Watching the Mind Itself — All Four Truths in a Single, Compact Observation
Confident understanding now turns from the exhaustive analysis of external objects to something far more direct: observing nothing but the mind's own present stream of thought, and finding all four noble truths already fully present within that single observation.
如是勤修瑜伽行者，觀心相續，展轉別異，新新而生，或增或減，暫時而有，率爾現前，前後變易，是無常性。觀心相續，入取蘊攝，是為苦性。觀心相續，離第二法，是為空性。觀心相續，從眾緣生，不得自在，是無我性。
Thus, a practitioner diligently cultivating yogic discipline observes the mind's own continuity: ever shifting, ever distinct, arising newly moment after moment, now increasing, now diminishing, existing only momentarily, appearing suddenly, changing from before to after — this is its impermanent nature. Observing the mind's continuity as subsumed within the aggregates of grasping — this is its suffering nature. Observing the mind's continuity as apart from any second thing — this is its empty nature. Observing the mind's continuity as arisen from manifold conditions, ungoverning of itself — this is its selfless nature.
次復觀察此心相續，以愛為因、以愛為集、以愛為起、以愛為緣。如是名為悟入集諦。次復觀察此心相續所有擇滅，是永滅性、是永靜性、是永妙性、是永離性。如是名為悟入滅諦。
Next, one further observes this mind's continuity as having craving for its cause, craving for its accumulation, craving for its arising, craving for its condition — this is called entering into the truth of origin. Next, one further observes that this mind's continuity, once cut off by discerning wisdom, possesses a lasting extinction, a lasting stillness, a lasting sublimity, a lasting freedom — this is called entering into the truth of cessation.
Master Cháng Bǎi treats this passage as the treatise's own dramatic compression: everything so far demonstrated across six sense-bases, sixteen external categories, three realms of existence, and sixteen aspects of four truths now collapses onto a single, always-available object — the practitioner's own present thought. Watching one thought instantly replaced by the next, never twice the same, never resting even a moment, delivers impermanence directly. Recognizing that this very thought is itself a product of past craving and past karma — one of the five aggregates of grasping, not a neutral observer standing outside them — delivers suffering directly. Searching this same thought and finding no second, independent thing standing behind it as its owner delivers emptiness directly. And seeing that this thought's very arising depends entirely on causes and conditions coming together, incapable of governing even its own appearance, delivers no-self directly. He notes the same collapsing move repeats for the remaining two truths: this very thought, examined further, is seen to arise from craving in all four of its senses (cause, accumulation, arising, condition) — origin directly observed; and this same thought, once genuinely cut off by discerning wisdom rather than merely suppressed, is seen to carry within that very cutting-off a lasting extinction, stillness, sublimity, and freedom — cessation directly observed. Where the earlier "exhaustive nature" analysis worked outward across the whole of experience, this "true nature" analysis works inward to the one thing always present and always available: one's own mind, watched closely enough, already contains the entire teaching.
23. Section: The Single Moment Before Breakthrough — "Supreme Mundane Dharma," and How Not to Mistake Dullness for It
Confident understanding, having stripped away every trace of subtle pride and coarse conceit, arrives at a single, precisely described mental state standing right at the threshold of genuine breakthrough — and the treatise pauses here to warn, with two vivid cautionary tales, how easily this exact threshold gets mistaken for something else entirely.
彼於爾時，其心似滅，而非實滅；似無所緣，而非無緣。又於爾時，其心寂靜，雖似遠離，而非遠離。又於爾時，非美睡眠之所覆蓋，唯有分明無高、無下奢摩他行。
At that time, the mind seems extinguished, yet is not actually extinguished; it seems to have no object, yet is not actually objectless. At that time, the mind is still, and though it seems detached, it is not actually detached. And at that time, the mind is not covered over by pleasant drowsiness — there is only a lucid calm-abiding, neither elevated nor depressed.
復有一類，闇昧愚癡，於美睡眠之所覆蓋，其心似滅非實滅中，起增上慢，謂為現觀。此不如是。
There is, however, another kind of person who, dull and confused, covered over by a pleasant drowsiness, gives rise, within that same seeming-but-not-actual extinction, to an inflated conceit, believing it to be genuine direct realization. This is not what is meant here.
Master Cháng Bǎi treats "supreme mundane dharma" (世第一法) — the very last moment of an ordinary being's mind, one instant before stream-entry itself — as a state the treatise is unusually meticulous about describing precisely, because it is so easily counterfeited. Genuinely approaching it, the mind seems to have ceased, seems objectless, seems fully detached, yet none of these are actually true — the object has simply become subtle enough, and the sense of self thin enough, that it feels this way without literally being so; crucially, this state remains vividly lucid throughout, "neither elevated nor depressed," never covered by the dull, contented haziness of pleasant drowsiness. He passes along a story to illustrate the counterfeit directly: a fellow monastic who dozed off during sitting meditation, then declared afterward that his practice had reached a thoughtless state free of discursive wandering — and, confronted by others who had watched his body sway with sleep, simply denied it, insisting he had been aware the whole time. Master Cháng Bǎi is direct about the danger this poses: mistaking dull, sleepy stillness for genuine insight, or a first dhyāna's calm for stream-entry itself, is a serious misdiagnosis with real consequences — and, without a genuinely accomplished teacher to catch the error early, a practitioner drifting down a mistaken path can find it extraordinarily difficult to correct course once habituated to it, a warning the treatise itself is about to illustrate with a far graver example than a nodding-off meditator.
24. Section: MAJOR — Genuine Breakthrough at Last, Delivering Three Different Fruits
The instant after supreme mundane dharma, without any gap, genuine breakthrough occurs — 112 afflictions accumulated since beginningless time severed at a single stroke — and, depending entirely on how far a practitioner had already progressed on the mundane path, this single moment delivers one of three different fruits: non-return, once-return, or stream-entry itself.
從此無間，於前所觀諸聖諦理，起內作意；作意無間，隨前次第所觀諸諦……如其次第，有無分別決定智、現見智生。由此生故，三界所繫見道所斷附屬所依諸煩惱品一切麤重，皆悉永斷。
Immediately following this, without any gap, one gives rise to an inward engagement with respect to the principle of the noble truths already observed; and this engagement, without any gap, following the same sequence already observed … gives rise, in due order, to a non-discriminating, decisive wisdom — a wisdom of direct seeing. Because this arises, every coarse affliction of the three realms bound up with what is severed on the path of seeing is permanently and entirely cut off.
此永斷故，若先已離欲界貪者，彼於今時既入如是諦現觀已，得不還果……若先倍離欲界貪者……得一來果……若先未離欲界貪者，彼於今時既入如是諦現觀已，麤重永息，得預流果。
Because of this permanent severance: if one had already become free of desire-realm craving beforehand, then, having now entered this direct realization of the truths, one attains the fruit of non-return … if one had already become more than halfway free of desire-realm craving, one attains the fruit of once-return … and if one had not yet become free of desire-realm craving at all, then, having now entered this direct realization of the truths, the coarse afflictions are permanently stilled, and one attains the fruit of stream-entry.
Master Cháng Bǎi treats this as the fascicle's genuine climax, structurally mirroring fascicle 33's culmination-of-effort delivering the first dhyāna without any gap: the exact same "supreme mundane dharma" moment, depending entirely on how much of the mundane path a practitioner had already completed beforehand, opens onto three entirely different destinations. A practitioner who had already fully mastered the mundane path's absorptions — genuinely free of desire-realm craving through the first dhyāna or beyond — finds this breakthrough delivers non-return directly, skipping stream-entry and once-return entirely, since the desire realm's nine grades of afflictions were already suppressed by dhyāna and are now, at last, genuinely uprooted rather than merely held down; such a person will take one final rebirth in the form or formless realms and reach final nirvāṇa there, never returning to this world. A practitioner more than halfway there — having already suppressed six to eight of the desire realm's nine grades — attains once-return, needing one more round of birth in the human or heavenly realm before arhatship. And a practitioner who had not yet suppressed desire-realm craving at all attains stream-entry, the most modest but no less genuine of the three, with the 112 afflictions arising from ignorance of the four truths (five sharp views plus five dull afflictions, multiplied across the desire realm's forty and the form/formless realms' seventy-two) now permanently uprooted, guaranteeing this practitioner will never again fall into a lower rebirth. He stresses the striking implication: the mundane path detailed at such length in fascicle 33 is never wasted effort even though it cannot itself uproot a single affliction's seed — it determines, quite precisely, which of these three doors this same single moment of breakthrough opens onto.
25. What "Direct Realization" Actually Means — Knower and Known, Finally of One Kind
The treatise closes this section by defining exactly what "direct realization" (現觀) means at the technical level — not a metaphor, but the precise state in which the knowing mind and the known object are, for the first time, of an identical nature, with no residual gap between them.
由能知智與所知境和合無乖，現前觀察，故名現觀。如剎帝利與剎帝利和合無乖，現前觀察，名為現觀。婆羅門等，當知亦爾。
Because the knowing wisdom and the known object come together without any discord, directly observing one another, this is called direct realization — just as a member of the ruling caste, together with another of the same ruling caste, comes together without any discord, directly recognizing one another, is called direct realization; the same should be understood for a member of the priestly caste and the like.
Master Cháng Bǎi unpacks the treatise's own chosen illustration — two members of the same caste recognizing one another without any friction of category, since both are already, simply, the same kind of thing — as a precise technical analogy rather than a decorative one: prior to this breakthrough, even a sincere and well-practiced mind still relates to emptiness and no-self as an object somewhat apart from itself, something aimed at rather than already shared; at the moment of genuine direct realization, the wisdom doing the knowing and the reality being known are, for the first time, not two things in relation at all, but a single seamless "coming together without discord" — precisely because the knowing itself has become selfless in exactly the way its object, emptiness, already was, so there is finally nothing left over to create the friction of a knower regarding a known. This is why the treatise insists this moment cannot be produced by an external source, however excellent the teacher or however correct the doctrine received — it is necessarily each individual's own direct, internal realization, arising only once wisdom and reality are no longer two different kinds of thing needing to be reconciled, but one and the same from the start.
26. Same Outward Calm, Different Inward Fate — and a Monk Who Mistook a Dead End for Liberation
A non-returner and a mere first-dhyāna practitioner display identical outward marks — settled posture, gentle speech, an unshakeable calm — yet one has genuinely uprooted the seeds of affliction and the other has only suppressed them. A sobering story from the *Great Commentary* shows how catastrophic that difference can be when a well-meaning practitioner gets it wrong.
彼與前說離欲者相，當知無異。然於此中少有差別。謂當受化生，即於彼處當般涅槃，不復還來生此世間。
That person's marks, one should know, are no different from the marks of one free of desire already described. Yet there is here a slight distinction: such a person will take spontaneous rebirth, and precisely there attain final nirvāṇa, never again returning to be reborn in this world.
Master Cháng Bǎi stresses that outward marks alone cannot distinguish a non-returner, whose desire-realm afflictions are genuinely uprooted at the root, from a mere dhyāna-practitioner whose identical calm rests only on temporary suppression — a slower-burning version of the drowsy meditator's mistake from two sections earlier, but with far higher stakes. He tells the *Great Commentary*'s cautionary story in full: an unlearned monk, sincerely practicing meditation, reached the fourth dhyāna, then judged feeling and perception themselves to be nothing but disturbance, and — without ever actually investigating the four truths — cultivated revulsion toward them directly, arriving at the attainment of no-perception, an outside path's dead end rather than genuine liberation. Within the community he looked, by every visible sign, like an accomplished practitioner: settled body, gentle speech, apparent freedom from greed and anger, widely admired and assumed to have attained the fruit. One arhat, however, checked directly and saw the mistake, warning him plainly: continuing this way leads only to five hundred years in the heaven of no-perception, followed by a rebirth with dulled faculties, no memory of cause and effect, and a nihilistic view of causation — urging him to switch to genuine cultivation of the four truths instead. The monk agreed and tried — but found he simply could not redirect his practice, so thoroughly had it habituated itself toward the wrong object, and died still bound for that same dead end. Master Cháng Bǎi draws the lesson bluntly: correcting course becomes exponentially harder the longer a wrong direction is reinforced, which is exactly why a genuinely accomplished teacher who can check one's actual progress, rather than merely praise its outward appearance, matters so much — and why a practitioner should never assume attainment from resemblance alone, no matter how impressive that resemblance looks from the outside.
27. Section: The Stream-Enterer's Marks — Four Knowledges, and a Lazy Brahmin Learns No One Can Practice for Him
Genuine stream-entry brings a cluster of concrete marks: four new kinds of wisdom, the ability to dissolve even fierce affliction almost instantly, an unshakeable independence from any external teacher — illustrated by a story of the Buddha himself declining to simply hand a lazy questioner the insight he wanted.
謂證如是諦現觀故，獲得四智。謂於一切若行、若住諸作意中，善推求故，得唯法智、得非斷智、得非常智、得緣生行如幻事智……唯自見法、得法、知法、證法源底，越度疑惑，不由他緣；於大師教，非他所引。
Because of realizing direct realization of the truths, one attains four kinds of knowledge — knowledge of mere phenomena, knowledge of non-annihilation, knowledge of non-permanence, and knowledge that conditioned processes are like an illusion … one alone sees the phenomenon, attains the phenomenon, knows the phenomenon, and fathoms the phenomenon to its very source, crossing beyond doubt, not by reliance on another; with respect to the Teacher's own instruction, one is not led by anyone else.
稽首此人間，勇猛真梵志，淨眼普觀照，願能除我疑。……我於脫汝疑，必無自在力，要汝見勝法，方得越瀑流。
Homage to you, most valiant one in this human realm, a true and holy seeker, whose pure eye sees all things — may you remove my doubt! … I have, in truth, no power to free you from your doubt; only if you yourself see the excellent teaching will you cross beyond the flood.
Master Cháng Bǎi lists the stream-enterer's marks as a cluster confirming genuine, not merely apparent, breakthrough: four new kinds of wisdom (that a being is nothing but phenomena, with no self hiding inside; that conditioned existence, though momentary, never simply annihilates itself into nothing so long as conditions persist; that it is likewise never permanent; and that it is illusion-like, real in function yet empty of any fixed nature); the ability to dissolve even a flare of fierce affliction almost as fast as a drop of water evaporates on a hot pan; a guarantee of never again falling to a lower rebirth, never breaking a precept on purpose, never committing any of the five heinous acts; and, most strikingly, complete independence from any external validation — never again bowing to a rival teacher as a genuine field of merit, never watching another's face or listening for their tone the way an unconvinced seeker still does. He tells the story of a lazy Brahmin named Dàodéjiā, too indolent to actually practice, who instead approached the Buddha with elaborate flattery, asking to simply be handed freedom from doubt; the Buddha's answer refuses the shortcut outright — no more than eating a meal on someone else's behalf could satisfy their hunger, or taking medicine oneself could cure another's illness, could the Buddha simply transfer insight to a mind that had not itself done the work of seeing. Master Cháng Bǎi draws the point sharply: if enlightenment could be granted by another's power alone, every being would already be a Buddha the moment the Buddha himself attained awakening — since this plainly isn't so, crossing doubt is necessarily each person's own labor, "like father and son climbing a mountain, each must make the climb himself." He closes by noting the stream-enterer's guaranteed ceiling: no more than seven more rounds of birth among gods and humans remain even for the least diligent, with arhatship certain by the seventh, and a stream-enterer's confidence in the Three Jewels and the precepts, now called "the four attainments of purified faith," has become completely unshakeable.
28. The Once-Returner's Sharper Edge, and What "Cultivation" Itself Actually Means
A once-returner shares every mark of a stream-enterer but with a sharper edge — only the mildest afflictions ever flare, and only one further rebirth remains. The treatise then pauses to define cultivation itself: what practice's own nature is, and the eight distinct things "practice" can actually accomplish.
然少差別。謂若行境界，於能隨順上品猛利煩惱纏處，由失念故，暫起微劣諸煩惱纏，尋能作意，速疾除遣。唯一度來生此世間，便能究竟作苦邊際。
There is, however, a slight distinction: even in circumstances conducive to fierce, upper-grade affliction, should mindfulness lapse, only a mild, inferior affliction ever briefly flares — and engagement immediately dispels it. Coming to be reborn in this world only one more time, one is thereby able to reach the very limit of suffering.
謂由定地作意，於世出世善有為法修習增長，無間所作、殷重所作，令心相續會彼體性。如是名為修之自性……當知修業略有八種。一、有一類法由修故得，二、有一類法由修故習，三、有一類法由修故淨，四、有一類法由修故遣，五、有一類法由修故知，六、有一類法由修故斷，七、有一類法由修故證，八、有一類法由修故遠。
Through mental engagement resting on concentration, one cultivates and increases wholesome, conditioned things both mundane and supramundane, doing so without interruption and with earnest care, so that the mind's continuity comes to embody that very nature — this is cultivation's own nature … one should know cultivation's function is, in brief, of eight kinds: some things are attained through cultivation, some are practiced through cultivation, some are purified through cultivation, some are dispelled through cultivation, some are known through cultivation, some are severed through cultivation, some are realized through cultivation, and some are distanced through cultivation.
Master Cháng Bǎi notes the once-returner shares the stream-enterer's entire list of marks but at a sharper pitch — where a stream-enterer can still, on a lapse of mindfulness, experience a genuinely fierce afflictive flare (dispelled quickly, but real while it lasts), a once-returner's equivalent lapse produces only the mildest flicker, and where a stream-enterer faces up to seven more rounds of rebirth, a once-returner faces only one. He then treats the treatise's turn to define cultivation itself as a valuable pause for perspective, cutting cleanly across every specific practice already described: cultivation's own nature is simply sustained, careful, uninterrupted engagement — in concentration, toward whatever wholesome quality, mundane or supramundane, one aims at — until the mind's own continuity has genuinely come to embody that quality rather than merely visit it occasionally. Its eight distinct functions then map onto every stage a practitioner might presently be in: cultivation attains what was never yet gained (planting an altogether new seed); practices what was already gained, so it appears more readily (a first dhyāna, once attained, still needs repeated practice before it comes easily); purifies what was gained but is not yet free of its own residual afflictions (initial insight into the desire realm's aggregates needing to mature into insight covering the form and formless realms too, the "direct" and "analogical" knowledge already introduced); dispels an affliction's actual outbreak once mindfulness has lapsed; knows an affliction not yet arisen well enough, through contemplating the aggregates as disease, as a festering wound, as a lodged arrow, that it never gets the chance to arise at all; severs an affliction's underlying seed outright, on the uninterrupted path; realizes the liberation that severing delivers, on the very next moment's liberated path; and distances what was already severed at a lower stage, carrying it further still toward its most complete and final removal. He notes this eightfold scheme is not just abstract taxonomy — a practitioner puzzled about why progress feels stalled can generally locate themselves on this same list and see plainly what kind of further cultivation, out of these eight, is actually still called for.
29. Section: Vajra-Like Concentration — The Final Blow That Severs Every Remaining Seed
After eleven kinds of cultivation are named and gathering-joy's ongoing revulsion-and-longing is briefly reaffirmed, the treatise arrives at culmination itself: a single concentration, likened to a diamond, capable of shattering every last, subtlest afflictive seed across all three realms in one uninterrupted stroke.
彼即於此攝樂作意親近、修習、多修習故，有能無餘永斷修道所斷煩惱最後學位喻如金剛三摩地生。由此生故，便能永斷修道所斷一切煩惱。
Through closely cultivating and thoroughly cultivating this very gathering-joy engagement, at the final stage of one still in training, a concentration likened to a diamond arises, able to permanently and entirely sever whatever the path of cultivation is meant to sever. Because this arises, one is thereby able to permanently sever every affliction the path of cultivation severs.
譬如金剛，望餘一切末尼、真珠、琉璃、螺貝、璧玉、珊瑚等諸珍寶，最為堅固；能穿、能壞所餘寶物，非餘寶物所能穿壞……如是此三摩地，於諸有學三摩地中，最上、最勝、最為堅固；能壞一切所有煩惱，非上煩惱所能蔽伏。是故此三摩地名金剛喻。
Just as a diamond, compared with every other precious substance — gemstone, pearl, lapis lazuli, coral, and the rest — is the most unbreakable, able to cut and pierce every other precious substance while none of them can cut or pierce it in turn … so too this concentration, among every concentration still belonging to one in training, is the highest, the most excellent, the most unbreakable; able to destroy every affliction whatsoever, with no affliction above it able to obscure or suppress it in return. For this reason, this concentration is called diamond-like.
Master Cháng Bǎi treats this as the treatise arriving, at last, at the mechanism behind arhatship itself. Everything up to this point — learning the mark, confident understanding, the breakthrough delivering one of three fruits, gathering-joy's ongoing cultivation severing the desire realm's remaining grades of affliction one by one — has still left untouched the subtlest afflictive seeds clinging to the form and formless realms, all the way up to that barest flicker of self-attachment lodged in the peak of existence itself. Vajra-like concentration is what finally reaches even these: not a gradual wearing-down but a single decisive stroke, likened to a diamond precisely because a diamond alone among precious substances can cut every other substance while nothing can cut it in return — no affliction, however refined, can stand against this concentration, while this concentration leaves no affliction, however refined, standing. He notes this is explicitly still the concentration of "one in training" (有學位) — the very last moment before training itself is complete — so what happens the instant after it arises is the whole remaining question: does anything at all remain to be severed once a diamond has already cut through everything?
30. Section: MAJOR — Arhatship Itself: Every Seed Gone, Freely Abiding, the Banner of Pride Cast Down
The instant after vajra-like concentration, without any gap, every remaining afflictive seed across all three realms is severed at once — arhatship itself, described here not as a bare technical attainment but through a cluster of vivid images: escaping a locked door, climbing out of a deep pit, crossing a moat, and casting down pride's own towering banner.
從此金剛喻三摩地，無間永害一切煩惱品麤重種子，其心於彼究竟解脫，證得畢竟種性清淨……彼於爾時，成阿羅漢，諸漏已盡，所作已辦，無復所作，證得自義，盡諸有結。已正奉行如來聖教，心善解脫。
Immediately following this diamond-like concentration, without any gap, every coarse seed of every kind of affliction is permanently destroyed, and the mind attains ultimate liberation with respect to them, realizing the utterly pure nature that was always its final destiny … at that time, one becomes an arhat: the contaminants are exhausted, what was to be done is done, there is nothing further to do, one's own true benefit is realized, every fetter binding one to existence is exhausted. One has rightly carried out the Tathāgata's teaching in full, and the mind is thoroughly liberated.
離諸關鍵，已出深坑，已度深塹，已能摧伏彼伊師迦，是為真聖，摧滅高幢。
Free of every bolt and lock, one has climbed out of the deep pit, crossed the deep moat, and subdued that towering Iṣīkā mountain — this is the true noble one, who has cast down pride's own high banner.
Master Cháng Bǎi lists the marks that together define this final attainment: the knowledge that every affliction is now exhausted, and the further knowledge that no future suffering will ever arise again since its cause is entirely gone; a mind honestly and completely finished with the work the entire path was for, tied to none of the fetters — five lower, five upper — that bind ordinary beings to rebirth; and full possession of the ten qualities of one no longer in training, view through liberation and true knowledge together forming the completed eightfold path. He then unpacks the treatise's own vivid cluster of images for what this actually feels like from the inside, tracing each back to the *Compendium of Topics*' own gloss: the "bolt and lock" is the five lower fetters, already broken at non-return; the "deep pit" is nirvāṇa itself, mistaken by outsiders — who cling to some unchanging, ultimately real self even while agreeing the aggregates are not-self — as a terrifying void to fall into, a dread the arhat has entirely climbed free of, since nirvāṇa is understood not as annihilation but as the plain absence of anything ever needing to be feared there; the "deep moat" is this same dread, now fully crossed rather than merely approached; and "Iṣīkā," a proverbially towering reed-mountain used by certain eternalist outsiders as their image for an indestructible, permanent self and an equally permanent world, is subdued the instant self-view itself is uprooted — pride's own "high banner," raised only ever in defense of a self that was never actually there to defend, finally and permanently cast down. He adds a sobering aside: precisely because such deeply rooted wrong views, once fortified by strong meditative concentration, become nearly impossible to dislodge through ordinary persuasion, buddhas and bodhisattvas find beings in the higher realms far harder to guide than desire-realm beings still humble enough to actually listen — a caution to take up genuine practice now, before deep concentration alone hardens a view too settled to reconsider.
31. A Real Monastic, Defined: Five Things Abandoned, Five Attained, Four Requisites Guarded
The treatise closes its portrait of arhatship with a concrete, almost job-description-like account of what genuinely defines "a true monastic" — five conducts permanently abandoned, five qualities permanently attained, and a fourfold discipline for guarding the four basic requisites of monastic life.
已斷五支，成就六支……一向守護四所依止。
Having abandoned five factors, one has accomplished the remaining factors … one guards, without exception, the four things one depends upon.
Master Cháng Bǎi lays out the five permanently abandoned conducts plainly: an arhat will never again deliberately kill, steal, engage in any sexual conduct whatsoever, knowingly speak falsely, or hoard and indulge in possessions beyond bare need — glossed in the *Stage of Thought-Constituted Wisdom* as five settled impossibilities (no going back to lay life, no hoarding for oneself, no lying even to save one's own life or gain, no theft, no illicit union), each guaranteed not by willpower alone but by the simple fact that the underlying craving that could ever motivate such acts no longer exists to be resisted. The five qualities attained fill out an equally concrete picture: no earning a living by any dishonest or manipulative means, however subtle (currying favor with the wealthy, advertising one's own reputation, teaching the Dharma as a transaction rather than a gift); valuing oneself so lightly that only the barest possessions are kept — clothes enough to cover the body, food enough to end hunger for the day, nothing saved past that day, all understood without a trace of resentment or self-pity; a genuine, wholehearted delight in the training itself, upheld even at the cost of life rather than broken for any lesser reason; permanent extinction of greed, hatred, and delusion; and complete liberation through the qualities already cultivated. He closes with the fourfold discipline for guarding food, clothing, bedding, and medicine — the four basic requisites every monastic depends on — glossed as four distinct kinds of guarding: guarding one's very livelihood (obtaining these only by honest means), guarding one's capacity to practice (using them only to sustain the strength needed for practice, never for indulgence), guarding the mind against affliction (preventing the six senses' contact with these very requisites from breeding any greed, anger, or unwholesome thought), and guarding right effort itself — a plain, almost domestic completion of the portrait, grounding arhatship's most exalted descriptions in the concrete daily discipline of an actual, ordinary-looking monastic life.
32. Section: The Monk Bitten by a Snake — Equanimity Tested at the Moment of Death
Rather than leave arhatship as an abstract description, the treatise's commentarial tradition preserves a full dramatic story — of two brothers, a betrayal, a vengeful rebirth as a snake, and a monk's genuine equanimity tested at the one moment that matters most: his own death.
最極遠離，獨一諦實，棄捨希求，無濁思惟，身行猗息……住戲論皆無，踰牆塹離愛，牟尼遊世間，天人不能識。
Utterly and finally free, singular and true, having relinquished all seeking, thought unclouded, bodily conduct wholly at ease … abiding beyond every proliferating conception, having crossed the wall and the moat, free of craving, the sage wanders through the world, and neither gods nor humans can recognize him.
梵行妙成立，聖道已善修，壽盡時歡喜，猶如捨毒器。
The holy life stands wonderfully accomplished, the noble path has been well cultivated; when life's span ends, one feels only joy — like setting down a jar of poison.
Master Cháng Bǎi tells the full story behind this verse, from the *Mūlasarvāstivāda Vinaya*: a wealthy elder's two sons, Dàjūn and Xiǎojūn, are left a fortune; Dàjūn travels abroad chasing ever more profit and stops writing home; his neglected wife, believing him dead, forces the reluctant Xiǎojūn to marry her rather than let her elope in disgrace, and she becomes pregnant just as word arrives that Dàjūn is finally returning. Terrified of the disgrace, Xiǎojūn flees into monastic life that same night; a doctor friend later gives an abortifacient to the wife without Xiǎojūn's involvement, but rumor blames Xiǎojūn directly, and the slander follows him even as he travels to Rājagṛha, takes up charnel-ground meditation on impurity at a compassionate new teacher's instruction, and swiftly attains arhatship — "seeing gold and dirt as the same, a knife's cut and sandalwood's perfume as no different, reaching into space with no attachment left at all." Dàjūn, returning to find his wife taken and his brother vanished, hires an assassin who instead kills Dàjūn himself when the king's protection of monastics makes Xiǎojūn untouchable — and Dàjūn, dying in fury, vows revenge, being reborn again and again as a snake in Xiǎojūn's own quarters, crushed by accident three times over (a door, a bed-leg) before finally, on the fourth rebirth, striking and killing him while he sat in meditation. Asked by Śāriputra, as the poison visibly took hold, why his face showed no distress, Xiǎojūn answered simply that the five aggregates were never his to lose, so the venom changed nothing that mattered — and Śāriputra, watching him die exactly as calmly as he had lived, offered the verses translated above, including the striking image of setting down a jar of poison with relief rather than resistance. Master Cháng Bǎi traces the whole chain back one further life: in a past existence as a hunter, Xiǎojūn had shot a meditating pratyekabuddha with a poisoned arrow out of frustrated rage at losing his hunting ground; the pratyekabuddha, moved to compassion rather than anger, displayed a miracle (water from the upper body, fire from the lower) before dying without a word of rebuke, and the hunter's resulting remorse-driven repentance lightened, but did not erase, a debt of poison that followed him across many further lives until this final one — a story he offers not as morbid trivia but as proof that even a genuine arhat's serene death is compatible with an entirely ordinary, even painful, physical cause, karma and liberation operating on two different registers at once.
33. FASCICLE 34 COMPLETE, THE GROUND OF THE HEARER-DISCIPLES CONCLUDES ENTIRELY, AND THE GROUND OF THE SOLITARY BUDDHA OPENS
The treatise closes its account of arhatship with the six qualities that define one who has ended the three poisons entirely, then delivers a single formal sentence closing the Ground of the Hearer-Disciples in its entirety — before immediately opening, in the very same fascicle, an entirely new ground: the Ground of the Solitary Buddha, complete in all five of its aspects.
如是一切名聲聞地。此是一切正等覺者所說一切聲聞相應教法根本，猶如一切名句文身是所制造文章、呪術、異論根本。
All of this together is called the Ground of the Hearer-Disciples. This is the root of every teaching on the hearer-disciples' path spoken by every fully awakened one — just as every collection of words, phrases, and syllables is the root from which composed writings, incantations, and diverse treatises are made.
本地分中獨覺地第十四。如是已說聲聞地。云何獨覺地？當知此地有五種相。一者、種性，二者、道，三者、習，四者、住，五者、行。
The fourteenth ground within the Basic Section: the Ground of the Solitary Buddha. The Ground of the Hearer-Disciples has now been fully explained. What is the Ground of the Solitary Buddha? One should know this ground has five aspects: lineage, path, habituation, abiding, and conduct.
Master Cháng Bǎi marks this as a genuinely momentous close: everything since fascicle roughly twenty of this treatise — the aspirant's stages, the provisions for renunciation, establishing categories of practice, the mundane path through the absorptions, and now the supramundane path through the four truths to arhatship — together constitute the single Ground of the Hearer-Disciples, explicitly named here as the root from which every teaching addressed to the hearer-disciple's path ultimately derives, just as the basic units of language underlie every more elaborate composition built from them. Rather than pause, the treatise turns immediately, in this same fascicle, to the fourteenth of the treatise's seventeen grounds — the Ground of the Solitary Buddha (the pratyekabuddha, one who awakens alone, without a living teacher, in an age when no buddha is present to teach). Its five aspects are named as a preview of the ground's own structure: what kind of disposition (lineage) inclines toward this path in the first place; what path or paths actually lead to it; what habituation across a solitary buddha's practice looks like; where and how such a being characteristically dwells; and how they actually conduct themselves once awakened. Master Cháng Bǎi notes the felt shift in register: where the Ground of the Hearer-Disciples spans dozens of fascicles built around a community of practitioners learning from teachers and scripture, the solitary buddha's ground, by definition, describes a path walked largely alone — a different flavor of practice built on the same underlying four truths and dependent origination, but oriented toward solitude rather than teaching, and toward silent example rather than spoken instruction.
34. Section: Three Kinds of Solitary-Buddha Disposition, and Three Paths to the Same Awakening
The Ground of the Solitary Buddha opens with its lineage aspect — three distinct temperaments that incline a person toward awakening alone rather than through a teacher — and its path aspect, distinguishing the rare "rhinoceros-horn" solitary buddha from the more common "group-practicing" kind who still awakens without a living teacher's instruction.
一者、本性獨覺，先未證得彼菩提時，有薄塵種性……二者……有薄悲種性……三者……有中根種性，是慢行類。由是因緣，深心希願無師、無敵而證菩提。
First, one inherently inclined to solitary awakening, before attaining that awakening, possesses a lineage of thin affliction … second … possesses a lineage of thin compassion … third … possesses a middling lineage, of the pride-inclined type; because of this, one deeply wishes to attain awakening without any teacher and without any rival.
謂有一類，安住獨覺種性，經於百劫，值佛出世，親近承事，成熟相續，專心求證獨覺菩提……於當來世，速能證得獨覺菩提。如是名為初獨覺道。
There is one kind who, abiding in the solitary-buddha lineage, over a hundred eons repeatedly encounters buddhas arising in the world, draws near and attends them, ripening in continuity, single-mindedly seeking to realize solitary awakening … in a future life, is thereby able to swiftly attain solitary awakening. This is called the first path of the solitary buddha.
Master Cháng Bǎi describes the three lineage-types as three different flavors of the same underlying inclination toward solitude: thin affliction produces a temperament that simply finds crowded, busy places unappealing and quiet solitude deeply appealing, without yet any particular insight; thin compassion produces someone who finds teaching and helping others tiring rather than rewarding, preferring minimal engagement and maximal stillness; and the pride-inclined middling type deeply wants to achieve awakening entirely on their own terms — with no teacher to thank and no rival to be compared against — a subtler version of the self-congratulation already flagged as an obstacle earlier in this same fascicle. He distinguishes the resulting three paths by how much a given solitary buddha actually relied on a teacher before awakening: the first, most classical path — the "rhinoceros-horn" type, solitary the way a rhinoceros's single horn is solitary — spends a full hundred eons repeatedly encountering buddhas, cultivating skill in the aggregates, sense-bases, elements, dependent origination, valid-and-invalid reasoning, and the four truths, until finally, in an age with no living buddha to teach, awakening arises entirely unaided, straight to arhatship without passing through the three lower fruits; the second path belongs to someone who, in the presence of a living buddha, only reaches the preparatory stages of heat, summit, and forbearance in this life, needing a future life (again without a teacher present) to complete the breakthrough; and the third belongs to someone who, again with a living buddha's guidance, actually reaches stream-entry or once-return in this life, but only completes arhatship later, unaided, in an age without a buddha — this last type explicitly capped at the desire realm alone, since a solitary buddha never completes their path in the form or formless realms. The *Treatise on the Great Perfection of Wisdom* sorts these into "great solitary buddhas" (the hundred-eon, rhinoceros-horn type, closest to a buddha's own thirty-two marks) and "conditions-awakened ones" (needing only a small trigger — a falling leaf, a scattering blossom — to spark insight into impermanence, without ever hearing a word of Dharma spoken).
35. FASCICLE 34 FULLY COMPLETE — Habituation, Dwelling, and Conduct Close the Ground of the Solitary Buddha
The remaining three aspects close swiftly: habituation distinguishes sudden from gradual liberation across the three paths; dwelling contrasts the rhinoceros-horn type's total solitude with the group-practicing type's willingness to live among others; and conduct describes how a solitary buddha actually moves through the world — teaching only by miracle, never by speech, always inclined toward quiescence.
當知此中，由初習故成獨覺者，名麟角喻；由第二、第三習故成獨勝者，名部行喻……謂初所習麟角喻獨覺，樂處孤林，樂獨居住……若第二、第三所習部行喻獨勝……亦樂部眾共相雜住。
One should know that a solitary buddha formed through the first habituation is called rhinoceros-horn-like; one formed through the second or third habituation is called group-practicing-like … the rhinoceros-horn-like solitary buddha, formed through the first habituation, delights in solitary forests, delights in dwelling alone … the group-practicing-like ones, formed through the second or third habituation, are also content to dwell mixed together with a community.
謂一切獨覺，隨依彼彼村邑聚落而住，善護其身、善守諸根、善住正念，隨入彼彼村邑聚落，或為乞食。或濟度他下劣愚昧，以身濟度，不以語言……唯現身相為彼說法，不發言故……又彼一切，應知本來一向趣寂。
Every solitary buddha, dwelling near this or that village or town, well guards the body, well guards the senses, and well abides in mindfulness, entering this or that village or town to beg for alms. They may deliver the lowly and confused, but do so through bodily manifestation, not through speech … they teach solely by manifesting bodily forms, never by uttering words … and all of them, one should know, are from the outset uniformly inclined toward quiescence.
Master Cháng Bǎi closes with the concrete texture of a solitary buddha's life: the rhinoceros-horn type genuinely lives and awakens alone, absorbed in contemplating dependent origination and resting in emptiness, marklessness, and wishlessness in total solitude; the group-practicing type, while sharing every other quality, is content living among a community even before or after awakening — the difference is companionship, not depth of realization. In conduct, every solitary buddha still enters town to beg, carefully guarding the senses exactly as described for the mundane path's beginner many fascicles earlier, but their manner of benefiting others is deliberately restricted: never through teaching in words, only through displaying miraculous bodily transformations — illustrated by the *Wise and Foolish Sūtra*'s tale of a wealthy woman born hideously disfigured as karmic result of having mocked and slandered a physically unappealing pratyekabuddha in a past life; that same pratyekabuddha, about to enter final nirvāṇa, displayed eighteen kinds of miraculous transformation for his patrons rather than a single word of reproach, and her resulting shame and sincere repentance was enough to restore her beauty in this present life — a solitary buddha's silence, Master Cháng Bǎi notes, is not indifference but a chosen method, teaching entirely through what is shown rather than what is said, all of it bent, from beginning to end, toward the single, quiet aim of nirvāṇa itself.
Fascicle 34 is now complete in its entirety — 35 sections, the full 5,507-line source read start to finish. This single fascicle accomplished an extraordinary double closure: it completed the supramundane path (seven mental engagements applied to the four noble truths, delivering stream-entry, once-return, non-return, and finally arhatship via vajra-like concentration), formally closed the ENTIRE Ground of the Hearer-Disciples spanning many fascicles of this treatise, and then opened and completed, within this same fascicle, the entire five-aspect Ground of the Solitary Buddha — lineage, path, habituation, dwelling, and conduct all now told in full. The next ground in the treatise's sequence of seventeen — the Ground of the Bodhisattva — lies ahead in the fascicles to come.
