这个概念在说什么

If you meet a Buddhist term that has been gently mistranslated into English as "transcendent wisdom," "pure wisdom," or "spiritual intelligence," you are looking at 無漏智. The mistranslation isn't wrong so much as it is too soft. 無漏智 is a precise technical term in the Abhidharma (阿毘達磨) toolkit: it names a *very specific kind* of knowing — one that has already done something to the one who knows.

Let me unpack the three characters, because the meaning lives in them.

第一,「漏」(āsrava) — what is leaking

"漏" literally means an outflow, an exudation, a seep. In the classical lists there are four of them: 欲漏 (kāmāsava, sensual outflowing), 有漏 (bhavāsava, outflowing of becoming/existence), 見漏 (diṭṭhāsava, outflowing of views), and 無明漏 (avijjāsava, outflowing of ignorance). These are not separate categories of bad thoughts. They are the *currents* by which a mind keeps circulating inside the three realms (欲界、色界、無色界). To be inside them is to keep being recycled — to taste a little, want more, hold the view that this is who I am, and remain fundamentally unclear about what is happening.

So 「漏」 names what keeps you bound. It is not a moral stain. It is structural.

第二,「無漏」 — what "non-leaking" actually means

Now the crucial classical line: 「有漏自地依,無漏隨生處」(*Abhidharmakośa*, T1558). Compare:

- 有漏慧 (defiled wisdom) is bound to its own ground (自地). If your ordinary discriminative understanding arises in the desire realm, it functions within the desire realm. If it arises in the form realm through a particular jhāna, it functions only there. The defiled mind can't escape its own address. - 無漏慧 (non-defiled wisdom) goes wherever it is born (隨生處). It is not bound to any one realm or any one jhāna. A sage who is born in the desire realm still has the 法智 for the desire realm; a sage born in the form realm still has the 類智 for the upper realms. The wisdom travels freely because it is no longer pulled by the currents of that ground.

Two consequences follow that you don't want to miss:

1. 無漏 is defined by what it has cut, not by what it feels like. A blissful, luminous, peaceful state of mind can still be 有漏 if it remains bound to the realm/jhāna producing it. A boring, dry moment of clarity can be 無漏 if the binding currents have been cut. The word tells you the *binding status*, not the *phenomenal quality*.

2. 「聖」 is reserved for it.慧有二種,有漏、無漏,唯無漏慧立以聖名」(T1558). Only this wisdom carries the title 聖. Good-hearted wisdom, brilliant wisdom, even samādhi-born wisdom — none of it earns the designation. Why? Because 「聖」 means "unbinding has happened to it." Not "the person is good." Not "the person is enlightened in feeling." The structural fact of having been cut.

第三,「智」 — why this word, not 「定」, not 「戒」

In the standard three-fold training 戒 (śīla, ethical conduct) → 定 (samādhi, meditative absorption) → 慧 (prajñā, discriminating understanding), 無漏智 is the *third leg, mature*. 「智」 is 慧 in its decisive, discriminating function — knowing *this* is suffering, *this* is the origin, *this* is cessation, *this* is the path. It is not the same as samādhi (a state of absorption) and not the same as ethical conduct (a discipline of action).

Within 無漏慧 itself the classical texts make a fine-grained distinction between 智 and 見 that you should keep in mind:

- 八忍 (the eight patient acceptances) are part of the path but not yet 智性, because the doubts they cut are not yet cut — they are still being cut. (Think: "I see this is true, but I'm still trembling.") - 八智 (the eight knowledges) are 智性 — the doubts have been decisively settled. - 盡智 and 無生智 (the wisdoms of "completed task" and "non-arising") are *not* 見性 — because the seeking-mind has come to rest. There is nothing left to probe. - All other 無漏慧 is both 智 and 見.

The reason this matters: 智 is decisiveness; 見 is the probing/looking quality. Once you arrive at 盡智 and 無生智, you stop looking. This is structural — the fuel of searching has been used up.

第四,where 無漏智 sits in the "ten wisdoms" (十智)

The *Abhidharmakośa* organizes all knowing into 十智 (ten kinds of wisdom). 「智十總有二,有漏無漏別,有漏稱世俗,無漏名法類」. So:

- 有漏總名「世俗智」(*saṃvṛti-jñāna*) — the wisdom that mostly takes up "pots and ordinary objects" (瓶等世俗境), the kind of knowing that ranges across everything conditioned and unconditioned as its object. This is ordinary cognition, refined cognition, scientific cognition, even deeply compassionate cognition — *if* it remains bound to its own ground. - 無漏分「法智」(dharma-jñāna) and 「類智」(anvaya-jñāna) — specifically: - 法智 takes the four noble truths (苦、集、滅、道) in the *desire realm* as its object. - 類智 takes the four noble truths in the *upper realms* (form and formless) as its object. - The remaining eight — 苦智、集智、滅智、道智、法智、類智、盡智、無生智 — are *all* 無漏. (苦、集、滅、道 are sometimes called the 「四諦智」; 法 and 類 are the 「諦觀」 distinguishing lower vs upper realms; 盡 and 無生 are the 「究竟智」 of completed task and non-arising.)

The crucial fact: the object of 無漏智 is not "everything." It is not the totality of phenomena. It is the four noble truths, partitioned by realm. This is a *narrow*, surgical object, not an all-encompassing gaze. Most of what passes for "wisdom" in everyday language has the whole world as its object; 無漏智 narrows its object precisely so it can cut precisely.

第五,the function: cutting, not knowing more

The functional line from T1558 is the cleanest: 「智遍知者,謂無漏智。斷遍知者,謂即諸斷」. Two kinds of 「遍知」 (full knowing): 智遍知 (the knowing itself, which is 無漏智) and 斷遍知 (the severing, which is the actual dissociations). They are paired: 無漏智 is the side that *knows*, the corresponding 斷 is the side that *cuts*.

A second line: 「無漏能斷惑,及諸淨近分」 — 無漏 can cut afflictions, and is associated with the *pure access concentrations* (淨近分, the near-but-not-yet absorptions leading to liberation).

In the *Mōhē Zhǐguān* (《摩訶止觀》, T1911), the same function is described dynamically rather than statically. 無漏智 is not an attainment to be stored; it is an *operation* with four sequential phases — 「方便、勝進、無礙、解脫」 (preparatory, advancing, unhindered, liberating) — and the result it produces is 「事理無生」: both the phenomenal and the theoretical arising are seen as non-arising. And it is deployed 「一向」 — exclusively, decisively — to break the subtle afflictions remaining in the highest formless attainment (非想非非想定).

The *Zhǐguān* also gives us a useful operational contrast: when 世間智 (worldly wisdom) cuts the 思惑 (deliberation-afflictions, the 81 layers across the three realms), the result is called 盡智 ("the task is done" — wisdom born from worldly cutting). When 無漏智 cuts them, the result is called 無生智 ("no more arising" — wisdom born from non-defiled cutting). Both are *wisdom of completion*, but the second is qualitatively different because the cutting instrument itself was never contaminated.

第六,無漏智 and 禪定 — a non-correspondence

A common modern assumption: deep jhāna → automatically 無漏. The *Zhǐguān* directly contradicts this. The same jhāna can be 有漏, 無漏, or 亦有漏亦無漏, depending on the *method*, not the *name*:

- The first three formless attainments (空處、識處、無所有處) are 亦有漏亦無漏 — they *can* give rise to the 无漏智 that exits the realm, so they have a 無漏 side. - The non-想非非想 attainment is mostly 有漏 but — some practitioners can, in fact, generate 無漏 from it. - Simply *engaging with the phenomena* of the ten jhānas (緣事修十禪) keeps you in 有漏 territory. - Only when jhāna is practiced 「緣諦智」 (taking the four truths as the object) or with the 「空無相心」 (mind of emptiness / signless) does it become 無漏. - Practices like 十六特勝 and 通明 are 亦有漏亦無漏 — ordinary practitioners stay on the 有漏 side; once instructed by a Tathāgata they can tip into 無漏. - 九想 (nine cemetery meditations) and 不淨 (impurity meditations) are classified as 無漏, because their disgust and desire-prevention are strong enough to issue in 出世智. They are called 「出世法施」 — gifts of the dharma that produce 出世.

The principle: 無漏 is determined by whether the practice issues in the wisdoms of the four truths, not by how deep, how blissful, or how stable the absorption is.

第七,the two obstructions and the limit of 二乘's 無漏

Finally, the *Zhǐguān* places 無漏智 within the framework of the two obstructions (二障): 煩惱障 (affliction-obstruction, with 愛/lust as its chief), and 智障 (cognitive obstruction, with 無明/ignorance as its substrate). 無明 here has two faces — obscuring principle (迷理) and obscuring phenomena (迷事).

Now the limit: the 二乘's 無漏智 is called 「人無我智」 and 「煩惱障淨智」. It clears the affliction-obstruction. It does not fully clear the cognitive-obstruction. The bodhisattva path, by contrast, aims at the full clearing of both. So 「無漏智」 is not automatically 「buddha-wisdom」 — it is a *family* of wisdoms spanning śrāvaka, pratyekabuddha, bodhisattva, and buddha, distinguished by how much of the two obstructions has been cleared.

This is why 「無漏智」 is best read as a *category with sub-levels*, not as a single attainment.


生活里的走查

Abstract so far. Let me walk this concept through a few scenes you almost certainly recognize, because the classical definition is rigorous and a contemporary reading has to map it rigorously too.

场景一:周一早上,地铁里刷手机

You are commuting. The news feed is full of strong takes — about geopolitics, about an industry you work in, about someone you don't know personally. Inside you, something is *forming*. You are constructing a position. You are agreeing with some posts, recoiling from others. By the time you exit the station you have a clear view, a clear emotional charge, and a small sense of self as "the kind of person who sees this correctly."

That whole operation — sharp discrimination, real understanding, even moral feeling — is operating as 世俗智. It is *real* knowing. It can range across everything conditioned and unconditioned. It is excellent at its job. And by the classical definition, it is fully 有漏: bound to its own ground (your ground is your habitual self-construal, your preferences, your ideological home), not free to go wherever it is born. The wisdom has not been cut loose from your 欲漏, your 見漏, your 無明漏.

This is not a critique of you. It is the normal state of a human mind. The concept's whole point is that *normal* doesn't mean *final*.

场景二:在心理諮商室,三个月後

You have spent weeks in therapy noticing a pattern — say, the way you collapse under criticism. Now, in a session, you *see* it. Not just intellectually; in your body, in your chest, the pattern reveals itself. The therapist asks, "What is this?" and you name it with precision. There is relief. There is clarity.

Now ask, by the classical test: is this 無漏智? Two things to check.

The first: has the *binding* been cut, or has the *pattern* been seen? 「智遍知」 versus 「斷遍知」. You may have achieved 智遍知 — the knowing — without yet achieving 斷遍知 — the severing. Many people have deeply true therapeutic insights that they correctly understand but still cannot break free from. The classical 八忍 stage is exactly this: "I see this is true, but the doubt is not yet decisively cut." 八忍 is still on the path; it is not yet 智性.

The second: even when insight lands, it still lands on the four noble truths, partitioned by realm. 法智 is about the desire realm — the realm of craving, becoming, view, and ignorance *in this very life, in this very body, with these very preferences*. If your insight is only an aesthetic insight ("I see the pattern as interesting") rather than as *suffering to be abandoned*, it has not yet met the actual object of 無漏智.

This is the most common contemporary confusion: *insight = 無漏智*. The classical definition says no. Insight that does not issue in cutting the binding is *still on the path*, but is not yet 智性.

场景三:禅修营第七天,出定後

You emerge from a deep sitting. Your mind is quiet, light, almost transparent. Colors look softer. Thoughts arrive without urgency. There is, for a few minutes, a subtle "I am the one experiencing this," but it doesn't sting.

If a contemporary teacher calls this 「開悟」 or 「進入無漏」, the classical framework pushes back, gently but firmly. The *Zhǐguān*'s principle applies: the question is not how the jhāna *felt*; it is whether it issued in 諦智 or 空無相心 — whether, while in or after that state, the four truths were seen with decisiveness, or whether emptiness/signlessness was actually penetrated. A luminous, peaceful jhāna with no such cutting is, structurally, 有漏. Even the fourth jhāna of the form realm, even the highest formless attainment, can be 有漏 if the cutting has not happened. (Recall: in 非想非非想定, the very *fineness* of remaining subtle afflictions is what 「一向用無漏智破」 is needed for.)

The deeper point: 「事理無生」 is not a feeling. It is a *seeing-through*. The phenomena don't appear, and the principles about phenomena don't appear, as arising. The dawn feeling after sitting can be a sign that conditions are ripening — or it can be a refined form of 漏, the beauty of a deeper self-absorption. 無漏智 is not what you feel. It is what has been cut.

场景四:失戀後三個月

You went through the breakup. The first month was denial. The second month was bargaining. Now, somewhere around month three, something shifts — not into happiness, but into *not needing it to be different*. You can pass the same cafe. You can hear her name. You can think about the future without her in it. The pain hasn't disappeared; the *clinging* to the alternative timeline has loosened.

This is closer, structurally, to what the *Zhǐguān* is describing. The 盡智 stage — 「the task is done」 — is not the absence of feeling; it is the absence of the *seeking* that powered the binding. 「已息求心,不推度故」 — the seeking-mind has ceased; there is no more probing for what could have been. That is why 盡智 and 無生智 are 「非見性」 — the probing quality of 見 has wound down, because there is nothing left to look for.

Whether this loosening in month three is full 無漏智 in the classical sense is another question — a human life has many realms and many 漏s, and one loosening does not equal all-out cutting. But *the structure* of the change — knowing, severing, and the cessation of the search — is what 無漏智 names.

场景五:AI模型面對自己的預測

A contemporary analogy, used with the caution the prompt asks for. A large model trained on a corpus can produce impressively accurate discriminations. It can "understand" the four truths in the sense of representing them. It can iterate through the sixteen cognitions (十六心) in a structured way. But:

- It is bound to its own ground — its training distribution. It does not 「隨生處」. It cannot step outside its own substrate. - It has no 漏 to be cut, and therefore the cut cannot be verified in the classical sense. There is no 欲漏, no 有漏, no 見漏, no 無明漏 being experienced from the inside. A model can simulate an enlightenment dialogue better than most humans can. It cannot be in one.

This is not a slam against AI. It is a clarification. **無漏智 names an achievement of a *first-person* binding-and-cutting**, not a third-person descriptive capacity. You can describe a sage's knowing perfectly and still be deeply 有漏. The classical 「聖」 is a structural fact about what is *not binding you anymore*, not an information state.

場景六:爭論中,對方說「我知道了」

A small, telling moment. In an argument, your counterpart finally says, "I see your point." But you can feel — and they probably can too — that they don't really see it; they are performing closure. The conversation is technically over; the doubt hasn't been cut. This is 八忍 territory in miniature: the form of decisiveness without the decisiveness itself.

Conversely, sometimes in an argument the other party *does* see it — and you can tell because they stop pushing. Not because they've given up; because the search has ceased. 「已息求心」. This is closer to 盡智 territory.

The classical distinction gives you a diagnostic tool you can use in everyday conversation: is this 八忍 (I see it but the doubt still holds), 八智 (the doubt is decisively cut), or 盡/無生 (no more seeking)? The same scale applies at the smallest scale of a single insight.

场景七:同樣的失敗,不同的人

You and a friend both lose your jobs. Two months later, you are functionally in similar external situations — looking for work, financial pressure, identity questions. But internally:

- You are still grinding — you wake up and the day is structured around restoring your position. The loss is a problem to be solved. This is fully 有漏; your discriminative wisdom is excellent and fully bound to the desire-realm ground. - Your friend, by contrast, after an initial scramble, has settled into a different relation to the loss. They are still acting — applying, networking — but the underlying *seeking to undo what happened* has softened. They are not attached to restoring the old self. Their discriminative wisdom is acting freely, not bound to the project of recovering a particular identity.

The classical test: same wisdom function, different binding. Your friend is not (yet) a 聖人. But the structural feature that the *Abhidharmakośa* is pointing at — wisdom not bound to its own ground — is visible in the difference.


当代人为什么需要它

You might be reading this and thinking: *I am not on a path toward becoming a sage. Why does this Abhidharma refinement matter to me?*

A few reasons, ordered from the most gentle to the most pointed.

1. It disarms a category error you are probably making. In contemporary culture, 「wisdom」 has become a fuzzy affirmative — emotional intelligence, cultural wisdom, indigenous wisdom, ancient wisdom, "wise beyond their years." All of these operate as 世俗智, often very refined. The classical concept of 無漏智 has the *nerve* to say: this is not the same thing, no matter how much you develop it. Without that distinction, the term "wisdom" does no work; it just flatters the speaker. With the distinction, you can ask, with rigor, what kind of knowing is happening in a given moment.

2. It names the most common contemporary spiritual failure: being smart while bound. We live in a culture that has made *being informed* into a moral status. Many of the most articulate, well-read, well-intentioned people are also the most thoroughly bound to their own positions — precisely because their discriminative capacities have been deployed in service of the binding rather than in its cutting. 「有漏自地依」 is a structural diagnosis of that condition. 無漏智 names the *other direction* — knowing that is no longer serving the home team.

3. It separates out the three classic moves and lets you diagnose yourself. Where are you, on the map?

- In 世俗智 — the whole range of conditioned knowing, including science, art, ethics, philosophy, ordinary mindfulness, therapy insights, and meditative jhāna without cutting? - In 八忍 — seeing something true but the doubt still holding? - In 八智 — the doubt cut, knowing with decisiveness? - In 盡智/無生智 — the seeking-mind at rest, the probing done?

The map is not a ladder you climb by effort. It is a diagnostic that lets you notice: in this moment, this relationship, this conflict, this conversation, which kind of knowing am I actually using? That noticing alone is not 無漏智 — but without it, you cannot tell whether what is happening is awakening or merely the next layer of self-confirming discrimination.

4. It protects the bodhisattva ideal from cheap substitutes. 「無漏智」 without the two-obstruction distinction collapses into 「I have arrived, I am enlightened, look at my wisdom.」 The *Zhǐguān*'s insistence that 二乘's 無漏智 is 「人無我智」、「煩惱障淨智」 — that it has *not* fully cleared the 智障 — is a structural safeguard against this. Even the most rigorous non-defiled wisdom of the śrāvaka path is a partial clearing. The bodhisattva vow is precisely to go further. The concept, taken seriously, resists the small-c claim of completion.

5. It anchors the practical in the precise. The *Zhǐguān*'s pairing of 無漏智 with specific methods (緣諦智, 空無相心, 九想, 不淨) is a refusal to let wisdom float. It insists: it is not enough to *say* you have non-defiled wisdom; you must be able to point to the practice that issues in it. In a contemporary scene saturated with claims of awakening, this is an important epistemic ask.

6. It connects to a canonical thread you can recognize. The *Heart Sūtra*'s 「照見五蘊皆空,度一切苦厄」 — seeing the five aggregates as empty, crossing all suffering — names the *result* of which 無漏智 is a major component. The *Heart Sūtra*'s 「無無明亦無無明盡」 — *no* ignorance and *no* ending of ignorance — sits in the precise slot the *Zhǐguān* opens: the 智障 is part of the structure, and its full clearing is a bodhisattva, not a śrāvaka, project. The *Diamond Sūtra*'s 「應無所住而生其心」 — the mind should be brought forth *without* abiding anywhere — is, structurally, 「無漏隨生處」 in its everyday form: a mind that functions everywhere because it isn't stuck anywhere. These canonical phrases, in different idioms, point at the same structural fact 無漏智 is naming.


常见误读与澄清

误读一:「無漏智」就是「很聪明」或者「很有智慧」

No. 世俗智 can be extraordinarily refined — a scientist, an artist, a therapist, a philosopher. The classical distinction is *not* about the brilliance of the knowing. It is about *what the knowing is bound to*. 「有漏自地依」 can describe the most brilliant human knowing; the binding status is structural, not qualitative.

误读二:「無漏智」就是「善良」或「正念」

No. 善良 and 正念 can still be 有漏 if they are bound to the practitioner as a self-image, a moral identity, a spiritual achievement. The 俱舍論 line 「唯無漏慧立以聖名」 is precise: the title 「聖」 is not for wholesome, kind, or mindful states. It is for the *severing* of the binding.

误读三:「無漏智」是禅定中那种非常清澈、非常宁静的经验

No. The *Zhǐguān* explicitly rules this out. A jhāna is not 無漏 by virtue of being deep or luminous. It is 無漏 only if it issues in the four-truth-knowing (緣諦智) or the mind of emptiness/signlessness (空無相心). The highest formless attainment itself is mostly 有漏 — the 「一向用無漏智破」 is required precisely because that state has subtle remaining 漏s that ordinary jhāna cannot touch.

误读四:「無漏智」就是「没有念头」或「空白的意识」

No. The eight consciousnesses (眼耳鼻舌身意、末那、阿賴耶) continue to function. The defilements are cut; the consciousness is not deleted. The classical model is not 「empty mind」; it is 「wisdom operating without binding currents.」

误读五:「無漏智」就是「开悟」或「证果」in the colloquial sense

Careful. In contemporary spiritual talk, 「开悟」 can mean almost anything — an insight, a peak experience, a felt sense of unity, a moment of grace. In the classical Abhidharma framework, 無漏智 is *one component* of awakening, with sub-levels (法智 / 類智 / 盡智 / 無生智) and sub-scopes (二乘 vs 菩薩 vs 佛). Saying 「I have 無漏智」 without specifying which kind, in which scope, with respect to which realm, is an unfinished sentence.

误读六:「無漏智」必须是佛的智慧

No. The *Zhǐguān* is explicit: 二乘的無漏智 is 「人無我智」, 「煩惱障淨智」. It is real, it is non-defiled, but it has not cleared the 智障. The bodhisattva's 無漏智 goes further; the buddha's 無漏智 clears both. 「無漏智」 is a family, not a single peak.

误读七:「無漏智」可以用「科學」或「腦科學」來證明

This one needs careful handling, because the analogy is tempting. Neuroscience can describe states of insight, change in default-mode-network activity during certain meditative attainments, the reduction of affective reactivity under certain practices. These are *contemporary descriptions of correlates*, not proofs of 無漏智. The classical concept makes three structural claims — (a) the four noble truths as the specific object, (b) severing of the three-realm binding, (c) non-bound operation across realms — that no neuroscience result, as of now, can confirm from the *first-person* side. Use the analogy to clarify; do not use science to certify.

误读八:「八忍」就是「無漏智」的一部分

Half-correct, half-mistaken. 八忍 are *on the path* to 無漏智, but the classical text is explicit: 「八忍非智性,自所斷疑未已斷故」. They are the *cutting* of doubt in process, not yet the knowing of the cutting. The 智性 arrives only at 八智. If you are in the middle of an insight and still feel the doubt trembling, you are in 八忍 territory, not 八智. The difference is structural.

误读九:「盡智」和「無生智」是同一件事

No. The *Zhǐguān* distinguishes them by the *instrument* of cutting: 世間智 斷 → 盡智; 無漏智 斷 → 無生智. The first arises from a still-contaminated knowing; the second from a non-defiled one. Both are 智; both are non-見性 (the probing has ceased). But their *origin* differs, and so does their depth.

误读十:「無漏智」一旦达到就永远不变

The classical texts do not make a strong metaphysical claim here. What they describe is the *operation* of 無漏智 — the four-phase 方便/勝進/無礙/解脫, the 一向 deployment against subtle 漏s, the 事理無生 as its work. This is not a static state; it is an active cutting that continues in the realm of practice. Treating it as a one-time badge you earn misreads the verb form of the classical language.

误读十一:「無漏」= Buddhist, 「有漏」= non-Buddhist

Tempting, but inaccurate. 「有漏自地依」 describes *all* ordinary knowing — including a Buddhist monk's *pre-awakening* mind. 「無漏隨生處」 describes a *quality of knowing*, not an affiliation. A Christian mystic whose wisdom is genuinely unbound to its own ground would, by the classical test, qualify as 無漏 in that domain — *if* the four-truth-knowing is the actual object. The criterion is structural, not sectarian.


結語

無漏智 is a difficult concept because it is both very old and very precise, and our contemporary language has lost the precision. The classical texts (T1558, T1911) build it carefully: as the wisdom that is not bound to its own ground, that ranges over the four noble truths as partitioned by realm, that comes in eight specific kinds (苦、集、滅、道、法、類、盡、無生), that operates through four phases to break subtle bindings and produce 事理無生, that includes 二乘's 人無我智 and goes beyond it, that does not automatically come with any particular jhāna but requires 緣諦智 or 空無相心, that alone gets the title 聖.

To live with this concept in a contemporary key is not to claim it. It is to use it as a *diagnostic*: where is my knowing bound? Is this 八忍 or 八智? Is this the 世俗智 I am calling wisdom, or is there any movement toward the kind of knowing that does not depend on its own ground? Is the calm in this jhāna 有漏 or 無漏? Is the insight in this therapy session 智遍知, or has the 斷 also happened?

These are questions you can ask tonight, on the commute home, before you open your phone. The concept is not asking you to become a sage. It is asking you to tell, with greater precision, what kind of knowing is happening in your mind right now.

Canonical EntryAI-generated

一、定义与核心要义

无漏智,梵语 anāsrava-jñāna,指已断离三界烦恼系缚、不随自地而起的出世间智慧。《俱舍论》以「有漏自地依,无漏随生处」标示其基本特征:有漏慧依自地而起,无漏慧随生处而得,不局限于一地。又云「慧有二种,有漏、无漏,唯无漏慧立以圣名」,明确唯有无漏慧方得「圣」称。《摩诃止观》则从功能面界定:无漏智并非静态的认识,而是实际用于破除定中细惑、推进解脱的观智,其运作次第具「方便、胜进、无碍、解脱」,由此成就「事理无生」。

二、主要阐述

十智中的摄属

《俱舍论》将无漏智置于十智体系中加以定位:「智十总有二,有漏无漏别,有漏称世俗,无漏名法类」。十智总摄一切智,依有漏、无漏性分为二:有漏总名「世俗智」,无漏分「法智」「类智」二种。世俗智「多取瓶等世俗境故」,「遍以一切有为无为为所缘境」;法、类二智「如其次第,以欲上界四谛为境」。苦、集、灭、道、法、类、尽、无生八智皆属无漏。

断惑功能

无漏智的核心功能在于断惑。《俱舍论》云:「智遍知者,谓无漏智。断遍知者,谓即诸断」,于「遍知」中分智遍知与断遍知,前者即无漏智,后者即诸离系之断。又颂「无漏能断惑,及诸净近分」。《摩诃止观》将「无漏智断」与「世智断」明确对举:若用世间智断除诸思惑,称为「尽智」;若由无漏智断除,则称为「无生智」。所断对象为三界「九九八十一品思惑」,惑尽即称「破法遍」。

与禅定的关系

《摩诃止观》指出,无漏与禅定的关系不依定的名称决定,而取决于修法及其能否引发出世智。前三种无色定「亦有漏亦无漏」,因能「发出世智」故名「亦无漏」;「非有想非无想」定被说为不发无漏、专属有漏,但又有人能在此定中「发无漏」。具体判别上:单纯缘事修习十禅,体相属有漏;以「缘谛智」或「空无相心」修习,方名无漏。十六特胜、通明等法,凡夫虽可修习却不必发无漏,经如来说示则亦能发无漏,故判为「亦有漏亦无漏」。九想、不净等因厌患、防欲之力强,能引发无漏,归入无漏,称为「出世法施」。判断无漏的着眼点在于能否导向出世、发起无漏,而不只在禅法属事禅还是理观。

智与见之差别

《俱舍论》细辨无漏慧中智、见之别:八忍「非智性,自所断疑未已断故」;尽智与无生智「非见性,已息求心不推度故」;其余无漏慧「皆通智见二性,已断自疑、推度性故」。论尽、无生二智时,引迦湿弥罗诸论师说:「从二智出后得智中作如是知」,即「我已知苦、不应更知」之自知相,乃无漏后得智之所表。

障蔽与对治

《摩诃止观》从障蔽角度说明无漏智的净化范围:烦恼障以爱为首,智障以无明为体;无明具迷理、迷事两面,因其障碍明解而名「智障」。二乘无漏被称为「人无我智」,并说为「烦恼障净智」。无漏智既与断爱、离烦恼相关,也以对治无明及其所成智障为重要语境。

三、不同部类与译本的表述差异

《俱舍论》(毘昙部·《阿毘達磨俱舍論》)以「无漏智」「无漏慧」「圣慧」并用,其中「圣慧」为该论对无漏慧之特称;以「法智、类智」特指无漏中之二种,「世俗智」则对称有漏智,一律以「无漏」统之。

《摩诃止观》(诸宗部·《摩訶止觀》)直接使用「无漏智」一语,以「出世智」「发无漏」为相近用语;在禅法判别中使用「漏、无漏」「有漏禅」「无漏禅」「亦有漏亦无漏」等术语;又用「二乘无漏」「人无我智」「烦恼障净智」等称呼。

两部文献用语体系各有侧重:《俱舍论》侧重「有漏/无漏」的二分框架,以「圣」字标示无漏慧之殊胜;《摩诃止观》则兼用「世智/无漏智」对举及「有漏/无漏/亦有漏亦无漏」的三分框架,且将无漏智与具体禅观修法紧密结合。

四、与相关概念的关系

世俗智:与无漏智构成对立范畴。世俗智遍以一切有为无为为所缘境,无漏智则以四谛为境。无诤行「但以俗智为性,第四静虑为其所依」,显示特定功用上仍依世俗智而非无漏智,由此划出二者之间的功能界线。

法智与类智:为无漏智内部之二分,法智以欲界四谛为境,类智以上界四谛为境。

尽智与无生智:《摩诃止观》以世智断惑所得为尽智、无漏智断惑所得为无生智;《俱舍论》则将尽智、无生智列为无漏智中二种,但强调其「非见性」。两部文献对尽智之归属表述不同。

禅定:无漏智与禅定非固定对应,同一禅定依修法不同可属有漏、无漏或亦有漏亦无漏,关键判准在于能否引发出世智。

二障:无漏智既对治以爱为首的烦恼障,也对治以无明为体的智障;但二乘无漏被称为「人无我智」「烦恼障净智」,显示其对治范围与菩萨道所说智障之完全净除有所不同。

五、代表性原文引用

《俱舍论》: - 「有漏自地依,无漏随生处。」 - 「慧有二种,有漏、无漏,唯无漏慧立以圣名。」 - 「智十总有二,有漏无漏别,有漏称世俗,无漏名法类。」 - 「智遍知者,谓无漏智。断遍知者,谓即诸断。」 - 「无漏能断惑,及诸净近分。」

《摩诃止观》: - 「一向用无漏智破」,成就「事理无生」。 - 「若用世间智断除诸思惑,称为尽智;若由无漏智断除,则称为无生智。」 - 前三种无色定「亦有漏亦无漏」,以能「发出世智」故。 - 以「缘谛智」或「空无相心」修习,方名无漏。 - 二乘无漏为「人无我智」,「烦恼障净智」。

入中論善顯密意疏B0044 · 藏傳論典部

《入中論善顯密意疏》對「無漏智」的論述,可從體性之安立、分位與階位、與二乘之差別、破斥倒見及斷習氣等幾方面歸納。

一、體性之安立:疏中首先辨明「無漏」之義。有部以「漏不隨增者,名為無漏」,疏斥其未解自宗安立無漏之義。自宗認為,凡為實執無明或彼習氣所染,即為有漏;離染之智乃是無漏。又引《顯句論》云:「離無明翳障諸智,非觀待無漏境性」,強調無漏乃就智慧本身離無明翳障而立,非觀待所觀境之性是否為「無漏」。

二、分位與修行階位:疏指出,未得佛地以來,未為無明習氣所染之智,唯是聖根本無分別智;然此智亦是暫時,從根本定起,仍生習氣為彼所染。乃至七地以來猶有無明染,八地以後與阿羅漢同樣斷盡能染之無明,但仍為無明習氣所染。故以「無漏智」為體性,就義別立前後分位,即各別諸地;一無漏智略以功德數量展轉增長等四門差別,安立為極喜等十地。

三、與二乘之差別:菩薩之聖根本智雖與二乘聖根本智同樣離無明習氣所染而現證法性,然安立為菩薩聖地者,須視其是否隨大悲轉、是否具足十二類百種功德等增上;又於資糧加行道中,是否以無量理門觀察二無我真義。

四、破斥倒見:疏破斥有說「無明及彼習氣盡時智慧亦滅」之論調,謂此同於觀行派外道妄計「垢盡心亦盡」之大斷見。引《寶鬘論》「名言說為心」明現見真理仍由心故,又引《法界讚》「猶如火浣衣」之喻——火能燒垢而不損衣,比喻智火燒心垢而光明心不隨之而盡。

五、習氣之斷除與一切種智:疏言諸佛由行一切種智之力,永斷貪等一切煩惱及諸習氣;二乘雖以無漏慧滅諸煩惱,然不能斷除習氣。釋論云「無明習氣能障了達所知」,此習氣屬所知障;聲聞獨覺唯有煩惱障斷,無明貪等習氣唯一切種智於成佛時始得永斷。十地最後心無間道現起,同時息滅最微細之習氣,而成最初解脫道,即是佛智第一剎那。

疏中所用術語值得注意:以「離染之智」「離無明翳之智慧」標舉無漏智之自性,以「聖根本無分別智」指其分位之智;又以「漏盡智力」稱佛斷盡煩惱習氣之智品,「一切種智」則特指成佛時究竟斷習氣之力,與二乘之「無漏慧」分屬不同層次。

大智度論T1509 · 釋經論部

《大智度論》論「無漏智」,首先置於十一智之分類框架中。論中列舉法智、比智、他心智、世智、苦智、集智、滅智、道智、盡智、無生智、如實智,逐一界定其體性與所緣。其中法智為「欲界繫法中無漏智」乃至「法智品中無漏智」,比智於色、無色界亦如是;苦智、集智、滅智、道智各於四諦觀時「得無漏智」或「無漏智」;盡智、無生智則於「我見苦已、斷集已、盡證已、修道已」之念中現起「無漏智慧見明覺」。論末總判:「十智,一有漏,八無漏,一當分別」——世智為有漏,他心智緣有漏心則有漏、緣無漏心則無漏,餘八智純屬無漏。

本論獨特之處,在於以摩訶衍立場將十智收歸一智。論中設難:「無漏智各各有所緣,無有能悉緣一切法者,唯有世俗智能緣一切法」,故一切智應是有漏相。答曰:「無漏智慧,何以故不能緣一切法?有漏智是假名虛誑,勢力少故,不應真實緣一切法。」進而明言:「是聲聞法中十智,摩訶衍法中有十一智,名為『如實相智』。是十智入是如實智中,都為一智,所謂無漏智;如十方水入大海水中,都為一味。」此即本論以「如實智」(又稱「如實相智」)統攝一切無漏智之核心命題。

就斷惑功能而言,論中設問:「諸阿羅漢、辟支佛同用無漏智,斷諸煩惱,習何以有盡、不盡?」答以智慧力有厚薄之別:聲聞、辟支佛「集諸功德、智慧不久,或一世、二世、三世」,智慧力薄「如世間火」;佛則「於無量阿僧祇劫廣修廣習,善法久熏故,於煩惱習無復餘氣」,力大「如劫盡火」。又云佛「斷結使智慧力甚利,用十力為大刀,以無礙智直過故,斷諸結使盡無復遺餘」,譬如國王誅重罪者七世根本,令無遺餘。

論中並錄諸家異說以明斷惑時節:或言「從得無生法忍來,得諸法實相故,一切煩惱及習盡」;或言佛「從初發意來有煩惱,至坐道場,於後夜時,斷一切煩惱及習」;或言佛「見定光佛已來已離欲,以方便力故,現有生死、妻子眷屬」。此諸說並陳而未遽定一是,顯示本論於無漏智斷惑之究竟時點持開放態度。

術語方面,本論通篇以「無漏智」「無漏智慧」為正名,未用「無分別智」等後起譯語;以「五受眾」稱五蘊(「五受眾無常、苦、空、無我」),以「結使」稱煩惱之異名,以「習」稱煩惱殘氣,皆為鳩摩羅什譯本之慣用詞形。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》論無漏智,首重其「斷惑」與「遍知」二義。論中明言「遍知有二:一智遍知、二斷遍知。智遍知者,謂無漏智;斷遍知者,謂即諸斷」,將無漏智直接等同於智遍知,即能遍知四諦之無漏智慧;而斷遍知則是所斷之離繫果,「此於果上立因名故」,以因(智)名呼果(斷),顯示無漏智為能斷之因、離繫為所斷之果。論中又詳說諸惑離繫隨道勝進,於治道起、得果、練根等六時重起勝得,而此能斷之道即無漏智所攝。

其次,論以「慧」之有漏、無漏二分統攝一切慧性,明言「唯無漏慧立以聖名」,即唯有無漏慧方得稱為聖慧,有漏慧雖亦名智,不得聖稱。於此聖慧中,論更細辨智與見之性相:八忍(苦法忍等)雖屬無漏慧,然「非智性,自所斷疑未已斷故」,以其猶帶推度,疑未永斷,故攝於見而不攝於智;盡智、無生智則「非見性,已息求心不推度故」,唯智非見;其餘無漏慧則通智、見二性,「已斷自疑、推度性故」。由此可知,本論所謂無漏智之「智」,須已斷自疑方得成立,與「忍」階位有嚴格分際。

再者,論引本論釋盡智、無生智之體相:盡智謂無學位正自知「我已知苦、我已斷集、我已證滅、我已修道」,無生智則進一步知「不應更知」「不應更修」。針對「如何無漏智可作如是知」之問,迦濕彌羅諸論師答以「從二智出後得智中作如是知」,即根本無漏智親證諦理時不作此分別,出觀後之後得智中方起此知,故無相違;亦有異師許無漏智自身亦作如是知,「然說見言乘言便故,或於諦理現照轉故」。此處顯示本論以根本、後得二分安立無漏智之運作層次。

末後,論以頌「無漏能斷惑,及諸淨近分」總標無漏智之功能:能斷煩惱,並能引發諸清淨近分定。全論以十智(世俗、法、類、苦、集、滅、道、他心、盡、無生)互相攝屬,無漏智貫穿其中,為見道、修道、無學道三階斷惑證真之根本能知。
