Entering the Character of the Knowable

This opens by drawing directly on the "hearing-habituation" (聞熏習) introduced back in Part 2 as the seed of the dharma-body, distinct from the ālayavijñāna's own defiled continuity. Just as the ālayavijñāna serves as the seed from which defiled experience continually arises, hearing-habituation — built up by listening to and reflecting on the Great Vehicle's teaching — serves as the seed from which correct mental discourse about the Dharma arises, complete with its own image-aspect that seems, at this stage, still to be grasping an object. "Mental discourse" (意言, roughly "inner speech") names the conceptual, verbal-feeling activity of thinking through the teaching before it deepens into direct, wordless realization — the entire process this part goes on to trace.

Vasubandhu is careful to distinguish this from any single dramatic qualification: it is a sustained history — a long continuum of hearing and reflecting on Mahāyāna teaching specifically (not just any teaching), long service to many buddhas, and conviction so settled that "bad companions" cannot shake it. He also traces a causal chain behind the phrase "well provisioned with merit and wisdom": the power of one's causes, the power of good friends, the power of one's own resolve, and the power of sustained support each build on the last, so that readiness to enter this path is itself the fruit of a long, gradual process rather than a sudden qualification appearing from nowhere.

Vasubandhu maps the four clauses directly onto four successive stages of the path: at the stage of resolute conduct — the long preparatory stage before direct realization — one enters simply through deep, settled conviction upon hearing that all is consciousness-only, without yet directly seeing it; at the path of seeing, one enters by correctly and directly penetrating this mental discourse, seeing that it is neither dharma nor object, neither what grasps nor what is grasped; at the path of cultivation, one enters by using that same seeing to counteract every remaining obstruction over repeated practice; and at the ultimate path — full buddhahood — one enters completely, since even the subtlest obstruction is by then entirely gone. The same single teaching, in other words, is engaged with differently at each stage of the path, deepening from conviction to direct insight to complete freedom.

Vasubandhu names the discouragement each reflection specifically counters. The first answers despair at the sheer scale of full awakening: if it seems too vast and distant a goal, remember that it is, in fact, being achieved constantly, by countless beings, this very moment — so there is nothing uniquely impossible about it. The second answers despair at the perfections themselves — generosity, patience, and the rest — seeming too difficult to perfect: a bodhisattva who has already gained genuine confidence and aspiration toward them needs comparatively little further effort to bring them to completion, the hard psychological work being the aspiration itself. The third addresses a subtler worry: if even ordinary, "obstructed" goodness (worldly virtue still mixed with attachment) reliably produces excellent rebirths, then goodness that has been made genuinely unobstructed — free of the very afflictions that limit ordinary virtue — could hardly fail to produce the ultimate fulfillment of buddhahood.

The four obstacles form a rough sequence, from coarse to subtle. Setting aside the Śrāvaka and Solitary-Buddha vehicles' own aims means genuinely committing to full buddhahood rather than merely personal liberation. Cutting off doubt about the Great Vehicle means being able to hold the seemingly contradictory language explored throughout Part 3 — dharmas described as without any self-nature yet also as illusion-like, dependent, and ultimately real — without wavering, once it is understood through the three natures. Cutting off grasping at dharmas addresses a subtler trap: even a practitioner who has abandoned self-grasping can still unconsciously treat the teachings themselves, or the dharmas described in scripture, as fixed, independently real things — which this obstacle removes. And the fourth, cutting off discrimination itself, is the most refined: even correct conceptual understanding still involves subtle mental labeling and categorizing, and full entry requires letting go of that activity as well, resting instead in bare, undistorted presence with whatever characteristics appear.

The four investigations and four kinds of thorough knowledge form a deliberate two-stage process, not four separate techniques. First, a practitioner investigates — questions and probes, without yet a settled conclusion — whether a name genuinely matches a real object's essential nature, whether a name genuinely matches its qualities, and so on across all four combinations. Investigation deepens into thorough knowledge once the answer is not merely suspected but directly, confidently realized: in every one of the four cases, nothing real underlies the name at all — it is entirely a provisional label. Vasubandhu is careful to specify the actual sequence: first one sees that the text (the word itself) is nothing but mental discourse; then that the meaning attached to that text is likewise nothing but mental discourse; only once both of these are seen does the deeper realization follow — that this "mental discourse" itself, the very medium of the investigation, is all there ultimately is. This is the technical machinery underlying what the site's Cheng Weishi Lun pages describe more briefly as realizing that "what is grasped is nothing but consciousness."

Vasubandhu reads the simile as a precise three-stage map of the three natures being entered one after another. Seeing that the "snake" was never there at all corresponds to seeing through the discriminated, attached-to nature: an object that seemed vividly present turns out to have no reality whatsoever. But something still remains once the illusion is dispelled — the rope itself, still cognized as a rope — and this corresponds to the dependent nature: real, conditioned, but itself still a construction built from more basic elements (its color, texture, and so on), just as "consciousness-only" is itself still a conceptual formulation, useful but not yet the final resting point. Only when even the rope is analyzed down to its ultimate constituents, and the cognition of "rope" itself is let go of, does something remain that need not itself be dissolved further — and this, Vasubandhu says, corresponds to the perfectly accomplished nature: even the thought "there is only consciousness" must eventually be released, not because it is false, but because it is still a conceptual formulation standing between the practitioner and the direct, non-conceptual realization the whole path is aimed at.

This passage completes the sequence begun with the rope-and-snake simile: even the correct, sophisticated insight "there is only consciousness" must ultimately be relinquished, not retained as a final resting formula, since it remains a name, a discrimination, and the goal is freedom from discrimination as such. What replaces it is direct, non-conceptual contact with the dharma-realm itself — described here as a state in which "the object known and the knowing are perfectly, equally alike," meaning that the usual gap between a knower and a known object has genuinely closed, rather than one side simply becoming more accurate about the other. The verse's ten-item list of "names" — Vasubandhu explains it fully — surveys every kind of naming a bodhisattva must eventually see through: individual dharmas, persons, categories of scripture, their meanings, concise and extended teachings, and finally the ultimate object shared by both fundamental and post-attainment wisdom — the true nature common to all dharmas alike.

This is the treatise's own account of the single most decisive moment on the entire bodhisattva path: the transition from an ordinary being to a noble one, entering the first of the ten grounds. "Born into the family of the Tathāgatas" means the lineage of buddhahood can never again be broken in this practitioner. The three kinds of "equal mind" that follow are, for Vasubandhu, three aspects of one realization: equality with all sentient beings, because one now genuinely wishes to be free of suffering exactly as much for others as for oneself; equality with all bodhisattvas, because one now shares their basic resolve and practice; and equality with all buddhas, because one has, in this moment, directly touched the same dharma-body every buddha has realized — different only in degree of completeness, not in kind.

Vasubandhu treats this passage as clarifying why entering consciousness-only matters practically, beyond the moment of insight itself: fundamental, non-discriminating wisdom alone cannot describe or teach anything, since it involves no discrimination whatsoever — it simply rests in direct seeing. A second kind of wisdom, "subsequently attained" once the meditator returns to active engagement with the world, is therefore also needed, and it is this second wisdom that lets a bodhisattva teach, reason about causes and effects, and act skillfully in the world without being fooled by appearances. The illusionist simile makes the point vivid: a skilled magician who has created an illusory elephant is never confused by his own illusion — he can describe it, explain how he produced it, and interact with an audience about it, all without mistaking it for a real elephant. A bodhisattva's post-attainment wisdom works the same way toward every appearance the ālayavijñāna produces: fully engaged, accurately described, never mistaken for independently real.

These four — heat, summit, acceptance, and the highest worldly dharma — are the classical "four aids to penetration" (順決擇分, nirvedhabhāgīya) shared across Buddhist Abhidharma traditions, here mapped precisely onto the four investigations and four kinds of thorough knowledge just described. "Heat" and "summit" correspond to weaker and stronger degrees of provisional acceptance that no object really exists, gained through investigation alone; "acceptance in conformity" marks the point where this is no longer merely accepted but genuinely, confidently known, through the completed four kinds of thorough knowledge; and "the highest worldly dharma" is the final instant before breakthrough, in which even the residual notion of "consciousness-only" is itself relinquished — the very last worldly moment before the path of seeing (described in section 9 above) actually opens. This four-stage scheme, shared with the site's Cheng Weishi Lun pages, names the precise psychological terrain a practitioner crosses in the moments immediately preceding the first genuine breakthrough into direct insight.

Having described the breakthrough moment in detail, the treatise moves quickly over what comes after it — the vast span of the path of cultivation, carried out across the ten bodhisattva grounds over an almost inconceivable length of time (a koṭi is traditionally ten million; a nayuta, a hundred thousand koṭis — the text is deliberately naming a number too large to hold in mind). Vasubandhu's gloss stays practical: the same two kinds of wisdom already introduced — non-discriminating wisdom directly realizing the general nature shared by all dharmas, and subsequently-attained wisdom skillfully engaging particular things — are simply exercised over and over, ground after ground, until the transformation of the basis (first explained in Part 2) is finally complete and the three bodies of buddhahood, the subject of Part 11, are fully realized.

Vasubandhu treats this list as a direct answer to a natural objection: if śrāvakas also directly realize truth and attain liberation, in what sense is a bodhisattva's realization actually different, rather than merely differently motivated? His answer, item by item, is that the difference runs through nearly every dimension of the realization itself, not just the practitioner's stated aim — a wider object of realization (both kinds of selflessness, not only personal selflessness), a different destination (non-abiding nirvāṇa rather than final cessation), a structured ground-by-ground path with no real śrāvaka parallel, and a fruit — the ten powers, fearlessnesses, and unique qualities of a buddha — that a śrāvaka's own attainment simply does not include. The bodhisattva path, on this reading, is not simply the śrāvaka path pursued with a bigger heart, but a structurally different realization from the very object it takes as its starting point.

Vasubandhu reads these two verses as a compact restatement of the entire path just described. "Name and thing are each incidental to the other" restates why neither can be the other's fixed essence, the same argument given in Part 3 for why the discriminated nature only seems to match a real substance. "There is only measure, and only provisional positing" names the dependent nature — real only as a functioning process of cognition ("measure"), with own-nature and qualities that are merely provisionally assigned labels. And "true wisdom observes that there is no object — there are only three kinds of discrimination" (discrimination of the name, of the own-nature, and of the differentiating quality) restates the entry into the perfectly accomplished nature: once even that threefold discrimination is seen to have nothing behind it, all three natures have been entered in turn — seeing through the discriminated (there is no object), understanding the dependent (there is only functioning discrimination), and finally not even holding onto that understanding as itself a further discrimination (the perfectly accomplished).

These two verses compress the whole path into four brief steps, drawn from a companion Yogācāra treatise the site translates elsewhere as the Madhyānta-vibhāga. First, a meditator recognizes that whatever image appears in meditation is simply mind itself, not some external object being reflected. Second, once the sense of an external object has genuinely dropped away, what remains is recognized as one's own conceiving activity, nothing more. Third — the step matching the rope-and-snake simile's second stage — the grasped object is seen to be absent, and then, further, the grasping mind itself is seen to be equally without independent existence, since "grasper" and "grasped" only ever made sense as a pair. And fourth, once both sides of that pair have dissolved, what is left is direct, non-conceptual contact with reality — described here, tersely, as "finding nothing further to attain," since there is no longer any gap between a knower and a known object left to close.

Vasubandhu reads these five verses as tracing the whole path in miniature, one verse per stage: the first describes the path of accumulation, where merit and wisdom are gathered without yet any direct breakthrough; the first half of the second verse describes the path of preparatory effort, where deliberate reflection brings the practitioner to the edge of realizing that meaning itself is only mental discourse; the second half of that verse, together with the moment both characteristics — the grasped and the grasper — are "swept away," describes the path of seeing already detailed earlier in this part; the fourth verse, with its image of non-discriminating wisdom flowing everywhere like medicine dissolving poison, describes the long path of cultivation across the ten grounds; and the fifth and final verse describes the ultimate path — buddhahood itself, wisdom finally settled at its very root within the dharma-realm. Read together with the rest of Part Four, these verses offer a compact aide-mémoire for the entire process this part has just described in full: from provisioning, through investigation, through breakthrough, through cultivation, to final arrival.
