What this concept is saying
Begin with the word itself. The Chinese character 漏 (āsrava) literally means "outflow," "leak," "seepage." The classical Buddhist image is not of sin, guilt, or moral stain in the Judeo-Christian sense. It is of a vessel with cracks: a container of attention, affection, and clarity that cannot hold what it receives. Whatever is poured in — peace, insight, intimacy, rest — drains out as quickly as it arrives. The mind registers a moment of calm and immediately leaks it into the next worry. A genuine feeling of love arises and leaks it into calculation. A flash of clarity comes and leaks it into distraction. The container is always emptying.
有漏 (sāsravatā) is the condition of the cracked vessel: outflow-prone, defiled, mixed. 無漏性 is the nature that emerges when the leaks are mended — but the term is more subtle than "perfection" or "purity" in the abstract. As the *Vaidikanyāyamañjuśrī* — no, rather, as the *Prabhāvardhikā-śāstra* (《顯揚聖教論》, *Vijñapti-mātratā-siddhi-śāstra* extended commentary by Asanga, T1602) — insists, 無漏性 is not first a moral adjective and then a metaphysical noun. It is a structural fact about how a mind works.
The text defines it with surgical precision: 無漏性即清淨一端之自性，與雜染之有漏性相對而立；更進一步，無漏性是「轉依相」——雜染轉為清清淨之轉變所依所顯現之相狀 ("non-defiled-nature is the self-nature of the pole of purity, set over against the defiled-nature of the pole of defilement; further, it is the *āśraya-parāvṛtti-lakṣaṇa*, the appearing-phase manifested by the basis on which transformation from defilement to purity occurs"). Two moves deserve to be held apart.
First move: definition by contrast. 無漏性 is defined *only* against 有漏性. You cannot grasp it as a standalone "goodness" — that would be a moralistic reading the Yogācāra tradition explicitly refuses. Purity here is not the opposite of impurity the way white is the opposite of black; it is what shows up when the leaking stops. To understand 無漏性, then, you have to first understand *the mechanism of leaking*: how a mind becomes defiled.
The *Prabhāvardhikā* explains this through the three natures (三自性, *tri-svabhāva*), a framework it inherits from the *Triṃśikā* and *Madhyānta-vibhāga* traditions. The mechanism runs as follows:
於依他起自性執著初自性故，起於熏習則成雜染；圓成實自性無執著故，起於熏習則成清淨。 "Because one grasps [as real] the first nature [遍計所執, *parikalpita*, imagined nature] upon the dependent nature [依他起, *paratantra*], habituation (熏習, *vāsanā*) arises and defilement becomes established. Because there is no grasping with respect to the perfected nature [圓成實, *pariniṣpanna*], habituation arises and purity becomes established."
This is the heart of the matter. Nothing in the Yogācāra analysis is more important. The dependent nature (依他起自性) refers to everything that arises dependently — sensations, thoughts, emotions, perceptions, the felt sense of self, other people, situations, even the Buddha's teaching. These are not, in themselves, defiled. They are conditioned events that arise through causes and conditions. Defilement does not inhere in them the way sugar dissolves in water.
What makes them defiled is grasping: the activity by which a dependent arising is taken to be a fixed essence — "this is me," "this is mine," "this is how things really are," "this must not change." That grasping is the *first nature*, the *parikalpita*, the imagined nature. The *Prabhāvardhikā* does not say grasping is an error in the way that miscalculating a sum is an error; it says grasping is itself a *further arising* (an additional dependent event) that, by its structure, pours dye into whatever it touches. The dye is 熏習, *vāsanā*, habituation — a tendency built up by being repeated, until the tendency saturates the stream of experience. When grasping saturates experience, the experience is *defiled*; the outflows (漏) become entrenched; the vessel leaks chronically.
Purity, then, is not the addition of something new. It is the cessation of the saturating dye, the mending of the vessel. The *pariniṣpanna*, the perfected nature, is the same dependent nature seen without the overlay of grasping — and the very fact that it can be seen without that overlay allows a different habituation to form: the habituation of non-grasping, which the text calls *vāsanā toward purity* (清淨之熏習).
So 無漏性, on this analysis, is not a substance injected into the mind. It is the appearing (相, *lakṣaṇa*) of a mind whose grasping-habit has been broken. That brings us to the second move.
Second move: 無漏性 is 轉依相. 轉依 (*āśraya-parāvṛtti*) is one of the most important technical terms in the Yogācāra vocabulary. 依 (*āśraya*) is the "basis" — the deepest stream of consciousness (ālaya-vijñāna) on which all other functions depend. 轉 (*parāvṛtti*) is "turning over," "reversing," "transformation." The mind's basis *turns over* — from being oriented around grasping to being oriented around non-grasping, from being a substrate of defilement to being a substrate of purity. This is not a single event but a process, and it has a direction.
Now here is the subtlety. 無漏性 is *not* the turning itself. The turning is the process. 無漏性 is the phase, the appearing-aspect, the manifested character (相) of what happens to the basis while and as it turns. It is the way the turned basis *looks from inside*, the way experience *feels and knows itself* once the leaking has been mended. You can think of it this way: a telescope, cleaned of mildew, looks through a clean lens — the cleanness of the lens is not a separate object added to the telescope; it is the appearing-quality of the telescope once the mildew is gone. 無漏性 is that appearing-quality.
This is why the *Prabhāvardhikā* insists 無漏性 cannot be located as a thing. It has no independent location, no essence separate from the basis, no self-standing existence. It is the way the basis manifests when the work of transformation has reached a certain stage. Remove the basis and there is no 無漏性; leave the basis untransformed and 無漏性 cannot appear.
This is also why the text pairs 無漏性 with 真如 (*tathatā*, suchness) as two things that are 不可思議 (acintya, inconceivable), and lists them in a single verse:
真如無漏性，成所作義利，靜慮者如來，無譬自在故。 "Suchness and non-defiled-nature, the perfected work of benefitting, the [states of] the meditator and the Thus-Come — [these are] inconceivable, because there is no analogy and because of [the Buddha's] inner mastery."
The long prose says: "In the two realms, that of the meditator (靜慮者, *dhyāyin*) and that of the Buddha, suchness and non-defiled-nature are both inconceivable. Furthermore, the Buddha's perfected work of benefiting sentient beings is also inconceivable."
Two reasons are given for the inconceivability. (1) 無譬 (no analogy): no worldly example can illustrate what these are like. You cannot point to a glass of clean water and say "that is 無漏性" — the cleanness of water is a surface property of a substance, not the appearing-quality of a turned basis. (2) 自在 (inner mastery, sovereign freedom): in the Buddha's case, 無漏性 is known from inside the turned basis itself. There is no external vantage from which it could be measured. The meditator (*dhyāyin*) approaches it; the Buddha fully realizes it; both find it unspeakable.
To put it in plain terms: 無漏性 cannot be defined by genus and differentia the way a botanist defines a flower. It cannot be pinned down by pointing. It cannot be inferred by analogy. It can only be known through the turning itself. This is a feature, not a bug, of the classical analysis. The whole point of the term is to mark the limit of objectifying knowledge.
生活里的走查 (Walking it through in contemporary life)
Now we need to walk this through scenes of contemporary life — but strictly by the classical definition. This is where most contemporary discussions slip, because 無漏性 sounds like "a clean state of mind," and almost everything in modern discourse about "letting go," "positive psychology," "mindfulness," or "authenticity" gets pressed into it. None of those maps cleanly onto the classical term. Let us go slowly.
Scene 1: The morning commute that goes wrong
You are on a crowded subway. Someone's bag knocks your coffee. You spill. The mind does several things in rapid order.
*依他起自性 (the dependent nature)* — this is the bare occurrence: the knock, the splash, the coolness on your hand, the sound, the rising pulse of heat in the chest. None of these are yet defiled or pure. They are simply arising, conditionedly. The classical analysis is not asking you to deny them, transcend them, or judge them. It is pointing out: these are the material.
*遍計所執 (the imagined nature, grasping)* — this is the overlay: "This always happens to me. People are thoughtless. I should have stood further back. This is going to ruin my shirt. Why don't people watch where they—" Each thought fixes a fluid event into an essence. The morning is no longer a flowing event but a story about you. The grasping has a structure: it seizes on the dependent arising and gives it a self, a past, a future, a meaning. This is the saturating dye.
*熏習 (habituation)* — this is what happens by repetition: the same story has been told ten thousand times. The story has a *vāsanā*, a settled groove. The mind, before the coffee spills, is already running the groove; when the coffee spills, the groove deepens. By the time you reach your stop, the morning feels contaminated. You carry it into the office. This is the *leaking* (漏) of 有漏性 — attention and good feeling draining out through the groove, leaving you with a residue of irritation, resentment, vigilance.
What would 無漏性 look like in this scene, by the classical definition? It would not be the absence of irritation (the dependent arising of heat in the chest is still happening). It would not be a mantra you recite. It would be the appearing-phase of a basis that is *no longer saturating the arising with grasping*. The heat appears; the heat is known; the heat passes. The container does not leak — meaning the moment does not bleed into the next moment as a story, does not saturate the next five hours as a mood.
Here is where the contemporary reader commonly maps wrong. The common mapping says: 無漏性 = "I stay calm" or "I react less." The classical analysis says: 無漏性 is the appearing of a basis in which the grasping-habit has been broken. Calm may accompany it; reactivity may not. The criterion is *the structure of grasping*, not the temperature of the affect.
Scene 2: The phone in the hand
You decide to check your phone for one second. Sixty minutes later, you surface, vaguely hollow. The dependent nature here is the sequence: notification, glance, recognition, motor impulse, scrolling. None of these are yet defiled. The grasping is: "I need to see this. I am the person who keeps up. I am behind if I don't. This content is *for me*. My worth is reflected in likes. My anxiety will be soothed by the next refresh." Each of these is a fixing of the dependent flow into a self-story.
The 漏 is the way awareness drains out of the moment — out of the meal in front of you, the conversation at the table, the work on the desk — and drains into the stream of feed. You are not losing calm; you are losing contact with what is happening. The leak is structural: it is the loss of the present dependent arising into a habitual overlay.
Where 無漏性 would touch this scene: not by banning the phone (that is moralism, not transformation), but by the moment when the basis, *from inside*, no longer takes the grasping-story as itself. The hand reaches; the hand pauses; the hand rests. Not because of willpower, but because the container is no longer pouring its contents into the grasping-groove. The hand has not been improved; the *āśraya* has turned.
Scene 3: The intimate argument
You and someone you love fight. The argument has the same shape it had last time, and the time before, and the time before. The dependent nature is the present words, the felt hurt, the body tension. The grasping is the overlay of character: "You are the kind of person who —" "I am the kind of person who —" "This is how it has always been —" "This will never change —"
The 漏 is the way each partner's awareness drains out of the present moment into the *vāsanā* of the pattern. By the time the fight ends, neither partner has been in the room. They have been in the past and the future.
無漏性 in this scene: not "we resolve the conflict" (that is a story about outcome), not "we forgive" (that is a moral verdict), but the appearing of a basis that, *in the middle of the arguing*, sees the grasping for what it is — an overlay, not the event. This is extremely difficult. The classical analysis does not promise that 無漏性 arises here on demand. It only promises that it is the direction in which the basis can turn. The argument may continue; the *āśraya* may nevertheless begin to turn underneath it. This is the meaning of 無漏性 as 轉依相 — the *appearing* of the turning, not the achievement of the turning.
Scene 4: Parenting at the end of a long day
A child will not sleep. You are exhausted. The dependent nature is the crying, the warmth of the small body, the tiredness, the distant worry about tomorrow. The grasping overlay: "I should be more patient. A good parent would —" "This child is difficult." "My parent did this to me." Each of these fixings turns a fluid night into a referendum on identity.
The 漏: the night drains you. Patience drains. Attentiveness drains. By morning, you have nothing left.
無漏性 in this scene: not the suppression of tiredness, not the achievement of patience, but the moment when the grasping-habit lets go of the situation long enough for the bare dependent arising — the crying, the warmth, the body's tiredness — to be known as such. The basis no longer runs the story; the basis turns, and the moment appears, and is what it is. The classical analysis here is not asking for sainthood. It is asking: can the basis turn even one degree? If yes, that one degree is 無漏性 appearing.
The most common mis-mappings, surfaced
In all four scenes, the same mapping errors recur. Hold them up clearly so we can spot them later.
- Mapping 無漏性 to "calm mind" — error. Calm is a contingent feeling; 無漏性 is a structural appearing. - Mapping 無漏性 to "absence of negative emotion" — error. Negative emotions are *dependent nature*; they are not, by themselves, defiling. - Mapping 無漏性 to "having mastered the technique" — error. 無漏性 is not a skill; it is the appearing of a turned basis. - Mapping 無漏性 to "moral purity" — error. The *Prabhāvardhikā* defines purity as *non-grasping*, not as good behavior. A person may behave well and still run a thick groove of grasping; a person may grasp and still act kindly. - Mapping 無漏性 to "enlightenment already attained" — error. 無漏性 is the appearing-phase of the turning; the turning has stages; the appearing changes accordingly.
Why contemporary people need this concept
Three reasons stand out, and they are worth saying slowly.
1. Modern discourse has flattened "purity" into moralism. When a contemporary reader hears "pure mind," the immediate associations are: morally upright, sexually restrained, emotionally neutral, judging others' impurity. This is the very thing the *Prabhāvardhikā* refuses. By defining 無漏性 strictly as the appearing of a basis whose grasping-habit is broken, the text shifts the conversation from moral evaluation to *structural observation*. You are not asked to be a better person; you are asked to see the difference between an event and the story that overlays it. This shift is precisely what is missing in most contemporary "self-improvement" vocabularies, where "purity" is still imagined as a quality to install rather than a leak to mend.
2. The metaphor of leakage maps uncannily onto what cognitive science now describes as attentional depletion and affective saturation. Contemporary research on attention, ego depletion, emotional contagion, and rumination describes a mind that loses its grip on the present moment through reinforcing habits. Some researchers (e.g., on default mode networks, on perseverative cognition) have noted patterns that look like the *vāsanā* dynamics the Yogācāra texts describe. But the similarity is a metaphor, not an identification. Cognitive science does not validate the Buddhist analysis; it offers a parallel vocabulary for what the Buddhist tradition was already describing in its own terms. The classical claim — that the leaking is *grounded in grasping-as-grasping-essence*, and that the leak stops when the grasping-as-grasping-essence stops — is not a claim cognitive science can confirm or deny. It belongs to a different order of inquiry. This needs to be marked, lest the contemporary reader think "neuroscience proves Buddhism."
3. The concept of 轉依相 gives us a non-possessive way to talk about growth. Most contemporary growth-models treat the self as a container to be filled: with skills, with confidence, with resilience, with positive experiences. 無漏性, by contrast, is not something added to the self. It is the *appearing of a basis that has turned*. This is liberating because it refuses the project of self-improvement-as-accumulation. You do not get 無漏性 the way you get a credential. The basis turns, and 無漏性 appears. You may notice its appearing. You cannot own it. This non-possessive framing is rare in contemporary discourse and is, I think, one of the most important things the classical concept offers.
Common misreadings and clarifications
Misreading 1: 無漏性 is a thing inside the mind, like a pearl. The classical analysis is explicit: 無漏性 is the **appearing (相, *lakṣaṇa*)** of the turned basis. It is not a substance, not a faculty, not a possession, not a stage of consciousness added to the existing eight. To treat it as a thing is to slip back into the very grasping the concept is meant to dismantle.
Misreading 2: 無漏性 is a static perfection. Because the term is defined as 轉依相 — the appearing of the *turning* — it is dynamic by its very definition. It is the character of a process underway. Different stages of the turning have different appearances. There is no single fixed "non-defiled nature" outside the process.
Misreading 3: 有漏 = bad, 無漏 = good. The classical text defines both poles structurally. 有漏性 is the appearing of a basis saturated with grasping. 無漏性 is the appearing of a basis whose grasping-habit is broken. Both are appearances of *the same basis* under different conditions. Neither is intrinsically good or bad. Morality enters through the *content* of grasping and the *content* of non-grasping, not through the bare fact of leaking or not leaking. A non-leaking vessel that holds cruelty is still a vessel of cruelty; a leaking vessel that holds kindness is still a vessel of kindness. The structure of the leak is independent of the moral quality of what is held. This is a subtle point that contemporary readers tend to skip.
Misreading 4: 無漏性 is identical to 真如. The *Prabhāvardhikā* lists them together as inconceivable, but it does not identify them. 真如 (*tathatā*) is suchness — the way things are, the suchness of dependent arising without the overlay of grasping. 無漏性 is the *appearing of the turned basis*. They are paired, not equated. One is the way things are; the other is the way the basis appears when oriented toward suchness.
Misreading 5: 無漏性 can be produced by effort. Effort, in the classical analysis, has its place, but 無漏性 is not the product of effort the way a chair is the product of carpentry. 無漏性 is the appearing of a basis whose grasping has been released. The release is not an *act* added to the existing flow of acts; it is the *cessation of the saturating overlay*. This is why the tradition distinguishes 止 (śamatha, calm abiding) and 觀 (vipaśyanā, clear seeing) — they prepare the basis for the turning, but the turning itself is not produced by them. The turning is something that happens to the basis when the conditions are ripe.
Misreading 6: 無漏性 is private and other-worldly. The same verse that lists 無漏性 as inconceivable also lists 諸佛成所作之義利 — the Buddha's perfected work of benefiting sentient beings. The pairing is deliberate. 無漏性 is not a withdrawal from the world; it is the appearing of a basis turned *toward* suchness, and suchness is the way the world is. The turning is therefore not away from the world but into the world's actual grain. The Buddha's "perfected work" is inconceivable precisely because it issues from this turned basis. The implication: 無漏性, when it appears, issues in a kind of action that cannot be predicted from the prior defiled condition. This is not mystical; it is the natural consequence of seeing without the grasping overlay.
A closing orientation
If you hold just one classical sentence from this material, hold this: 「此無漏性當知即是轉依相」 — "this non-defiled-nature is to be known precisely as the appearing-phase of the basis's transformation." It refuses the two temptations the modern reader faces most: the temptation to *substantialize* purity (treating it as a thing to acquire) and the temptation to *moralize* it (treating it as goodness to install). What remains is the harder, more interesting picture: a basis that turns, and a character that appears as it turns, and an unspeakable depth to that appearing.
That, in the Yogācāra tradition's most careful analysis, is what 無漏性 is. Not a goal. Not a possession. Not a feeling. The direction in which a mind can turn, and the way a turned mind appears from inside.
