What this concept is saying

無為 (wúwéi; Sanskrit: asaṃskṛta), “the unconditioned,” means that which is not fabricated by causes and conditions and does not pass through arising, abiding, alteration, and cessation. The *Saṃyukta Āgama* (《雜阿含經》) states the contrast precisely: conditioned phenomena undergo “arising, abiding, alteration, and cessation,” whereas the unconditioned is “不生、不住、不異、不滅”—not arisen, not abiding, not changing, and not ceasing.

This sounds abstract until we notice how thoroughly ordinary life belongs to the other side of the contrast. A body appears through conditions, changes, and dies. A mood arises when sleep, memory, hormones, circumstances, and attention converge; it remains briefly and dissolves. A career, a relationship, a political order, a star, and even a meditative state exist only while supporting conditions hold. These are 有為 (yǒuwéi; saṃskṛta), “conditioned” or “fabricated” phenomena.

無為 is not simply a particularly durable conditioned thing. It is not something produced successfully and then preserved forever. If it were produced, its existence would depend on the conditions that produced it; it would therefore still be conditioned. Nor is it merely a very calm mental state. Calm produced by silence, breathing, concentration, good health, or favorable surroundings arises conditionally and will change. However refined or valuable, such calm remains 有為.

The early discourses give the term its decisive soteriological content. The *Saṃyukta Āgama* does not leave 無為 as a metaphysical blank: it identifies it with the permanent exhaustion of greed, hatred, delusion, and all afflictions. It also identifies the Noble Eightfold Path—right view, right intention or understanding, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration—as the path leading toward the unconditioned. Thus 無為 has a definite place in the path of liberation:

- Conditioned existence is examined as unstable, unsatisfactory when grasped, and incapable of being possessed as a permanent self. - Craving, appropriation, and ignorance—the machinery that perpetuates suffering—are understood and relinquished. - Their irreversible exhaustion is nirvāṇa, the unconditioned.

The term therefore names both a contrast in the classification of phenomena and, in many scriptures, the liberating consummation toward which practice leads. Expressions such as “至無為處,” “reaching the unconditioned domain,” should not be read too literally as travel to a hidden location. They express arrival at safety, cessation, and freedom from the compulsions that sustain suffering. The *Ekottarika Āgama* (《增壹阿含經》) repeatedly uses this destination-like language and closely associates 無為 with nirvāṇa, freedom from birth, aging, illness, death, grief, and distress.

The *Mahāprajñāpāramitā Sūtra* (《摩訶般若波羅蜜經》) defines the unconditioned as “不生不住不滅”—not arising, abiding, or ceasing—and associates it with the exhaustion of greed, hatred, and delusion, as well as 如 (suchness), 法性 (dharma-nature), 法位 (the abiding order of dharmas), and 實際 (the ultimate limit or actuality). These are not simply interchangeable dictionary entries. They illuminate different aspects of what cannot be treated as another transient object: cessation emphasizes the ending of bondage; suchness emphasizes things as they actually are; dharma-nature and ultimate actuality emphasize reality free from conceptual fabrication.

But an essential warning follows. “Unconditioned” must not be turned into the name of an eternal object, cosmic substance, or hidden Self. The same Prajñāpāramitā tradition says that conditioned and unconditioned natures are neither joined nor separated and ultimately have “one characteristic—namely, no characteristic.” Their distinction functions in teaching, but wisdom does not solidify either side into an independently existing essence.

The *Ratnakūṭa* (《大寶積經》) presses this warning even further: nirvāṇa exceeds all conceptual movement and discrimination; there, even the designation “unconditioned” does not apply, much less “conditioned.” The point is not that liberation vanishes. It is that the liberated reality is not captured by the conceptual opposition through which we were guided toward it. A raft may be indispensable for crossing a river without becoming part of the far shore.

Different scholastic traditions classify 無為 differently, and their definitions should not be collapsed into a single loose list.

The *Abhidharmakośabhāṣya* (《阿毘達磨俱舍論》) teaches three unconditioned dharmas:

1. 虛空 (ākāśa), “space”: absence of obstruction. This does not mean the visible sky or outer space as a physical expanse. Physical space as measured by distance and occupied by matter belongs to conditioned experience. Here “space” is defined through non-obstruction.

2. 擇滅 (pratisaṃkhyā-nirodha), “cessation through discernment”: liberation or disconnection from defilements attained through discriminating wisdom. “Discernment” here is not ordinary choosing. It is the insight of the path by which bondage is abandoned. The path does not manufacture nirvāṇa; it enables cessation to be realized, just as removing bondage does not manufacture freedom as a new material object.

3. 非擇滅 (apratisaṃkhyā-nirodha), “cessation not through discernment”: the non-arising of a possible phenomenon because its necessary conditions are absent, not because liberating wisdom has destroyed the corresponding affliction. A missed train that can no longer be boarded illustrates irreversible non-occurrence in an everyday way, but it is only an analogy; the technical category is part of a precise Abhidharma analysis.

This distinction is indispensable. The mere absence of anger because nobody has contradicted us is not 擇滅. The conditions for anger may simply not have appeared. Even suppressing anger for an afternoon is not the irreversible exhaustion of hatred. Liberating cessation concerns the removal of bondage at its root.

Other systems organize the field differently. The *Yogācārabhūmi* (《瑜伽師地論》) presents eight: space, non-analytical cessation, analytical cessation, the suchness of wholesome, unwholesome, and neutral phenomena, immovability, and the cessation of perception and feeling. The *Treatise on the Hundred Dharmas* (《大乘百法明門論》) lists six: space, analytical cessation, non-analytical cessation, cessation through immovability, cessation of perception and feeling, and suchness. The *Cheng Weishi Lun* (《成唯識論》) discusses five—space, analytical cessation, non-analytical cessation, immovability, and cessation of perception and feeling—and says, “此五皆依真如假立”: all five are provisionally established on the basis of suchness. It immediately adds that “suchness” itself is also a provisionally established name.

These numerical differences are not an invitation to choose a favorite count. They arise from different analytical purposes. One system distinguishes kinds of cessation and non-obstruction; another adds modes in which suchness is disclosed; another emphasizes that none of these names denotes a separately existing thing outside mind and phenomena.

The Madhyamaka works apply the most radical safeguard. The *Mūlamadhyamaka-kārikā* tradition represented by the Chinese *Middle Treatise* (《中論》) concludes that “無為法但有名字”—the unconditioned has only a name—when imagined as something independently established over against conditioned things. The *Twelve-Gate Treatise* (《十二門論》) states that because conditioned phenomena are empty, the unconditioned is empty as well. “Empty” does not mean useless or nonexistent in a nihilistic sense. It means empty of independent, self-established nature. Since “unconditioned” is designated in contrast with “conditioned,” it cannot coherently be grasped as a self-standing metaphysical object.

This gives us three complementary registers:

- In early Buddhist practice, 無為 is the cessation of greed, hatred, delusion, and suffering: nirvāṇa as the goal of the path. - In Abhidharma, it is a technical category with carefully distinguished members such as space, analytical cessation, and non-analytical cessation. - In Prajñāpāramitā, Yogācāra, and Madhyamaka reflection, even the concept “unconditioned” must not become an object of attachment. It is taught, analyzed, and then freed from reification.

These registers need not be forced into one formula. They answer different questions: What is liberation? How should phenomena be classified? How do we prevent a liberating teaching from becoming a new metaphysical fixation?

The Mahāyāna adds one more decisive dimension. The *Vimalakīrti Sūtra* (《維摩詰所說經》) describes the bodhisattva path as “不盡有為,不住無為”—not exhausting the conditioned and not abiding in the unconditioned. This does not deny nirvāṇa. It refuses to turn freedom into withdrawal from beings. The bodhisattva is not inwardly enslaved by conditioned existence, yet continues to enter conditioned situations—illness, conflict, language, institutions, teaching, care—in order to benefit others. Wisdom does not cling to saṃsāra; compassion does not abandon it.

That is also why the famous line “應無所住而生其心”—“one should give rise to the mind without abiding anywhere”—from the *Diamond Sūtra* (《金剛般若波羅蜜經》) is relevant. It does not say to stop having a mind, suppress thought, or become inactive. It points to responsive activity without fixation. Later Chan texts, including Huangbo’s teachings, draw on precisely this logic when they speak of the “unconditioned mind” and the “idle person of unconditioned, ended learning.” Their language should be read as instruction against grasping, not as permission for passivity or anti-intellectualism.

A walkthrough in everyday life

Imagine a commuter standing in a crowded train after a difficult morning. A message appears on the phone: “Can we talk about your performance this afternoon?” The mind immediately constructs a crisis.

First, notice the conditioned field. The glowing screen depends on hardware, electricity, software, networks, corporate systems, and human intentions. The message depends on a sender, language, workplace history, and timing. The body’s reaction depends on sleep, prior stress, memories of criticism, physical health, and learned patterns. A tight chest arises; an image of being dismissed appears; resentment toward the manager follows; the thumb opens another app to escape the discomfort.

Every part of this sequence is 有為. It arose when conditions assembled. It remains only while conditions support it. It changes from moment to moment and ceases. Even the apparently solid thought “My career is collapsing” is a conditioned construction, not an oracle.

This does not yet mean that the phone, body, or thoughts are 無為. A common mapping error is to call the observing mind “the unconditioned” merely because it feels quieter than its contents. Attention is a mental event; ordinary awareness fluctuates with fatigue, illness, training, and stimulation. A spacious meditative experience may be exquisitely peaceful and still be conditioned.

Now the commuter practices right mindfulness: “Pressure in the chest. Fear. An image of humiliation. An impulse to flee.” This slows automatic identification. Right view recognizes that the message is present but the catastrophic future is being constructed. Right effort neither feeds the spiral nor violently suppresses it. Right speech prevents an impulsive hostile reply. Right action and livelihood guide an honest, non-harmful response. Concentration gives the mind enough steadiness to remain with what is actually happening.

These practices are also conditioned. They are cultivated through teachers, repetition, intention, memory, and supportive circumstances. Therefore the Noble Eightfold Path is not itself to be confused with the final unconditioned simply because it leads there. The *Saṃyukta Āgama* calls it the “track” or path toward 無為: medicine is not the same thing as the end of the disease.

Suppose the commuter’s anxiety subsides after ten minutes. That cessation is not automatically nirvāṇa or 擇滅. Perhaps attention shifted. Perhaps the train reached the station. Perhaps a reassuring follow-up message arrived. The episode ceased because its supporting conditions changed. Calling every moment of relief “the unconditioned” would erase the classical distinction between temporary calming and the extinction of bondage.

Now look more deeply. The practical question is not only, “How can I stop feeling anxious?” It is, “What makes this anxiety into bondage?” Perhaps there is craving for an invulnerable public identity, aversion to uncertainty, and the view that career status constitutes a permanent self. When these are unseen, each notification can activate the whole structure again. When they are understood directly and relinquished, the grip weakens at its root.

The same mapping can be followed through an intimate relationship. One partner says, “You never listen.” Sound occurs; recognition identifies the words; feeling registers pain; memory supplies earlier quarrels; volitional formations prepare defense; consciousness takes up one object after another. None of this is an unchanging self. Yet saying “everything is conditioned” must not become a sophisticated way of dismissing the partner. Ethical response remains part of the path: pause, hear the hurt beneath the accusation, acknowledge one’s conduct, and speak without retaliation.

If the quarrel stops because one partner leaves the room, that is an ordinary conditional cessation. If resentment remains latent, its conditions have merely gone quiet. If insight and cultivation uproot the greed, hatred, and delusion that turn disagreement into self-defense and injury, that points toward the liberating sense of cessation.

Consider parenting. A child has a public meltdown. The parent feels shame because strangers are watching. “A good parent would control this” appears as if it were an objective fact. The child’s exhaustion, the parent’s fatigue, the noisy environment, social comparison, and fear of judgment combine into anger. Seeing conditionality creates room for compassion: this event has causes; it is not the essence of the child or parent.

Yet 無為 does not mean refusing to intervene because “everything is empty.” The parent may still move the child to safety, set a boundary, offer food, or apologize after shouting. The bodhisattva principle—“not abiding in the unconditioned”—is especially vivid here. Non-attachment is not absence of care. It is care no longer organized around protecting a fixed image of “me.”

The same applies to algorithmic life. A recommendation system presents content based on data, optimization targets, commercial incentives, and previous behavior. Attention, irritation, and desire are then conditioned in return. It can be helpful to compare this loop with Buddhist accounts of conditioned reactivity: input, recognition, feeling, craving, action, reinforcement. But the comparison has limits. A computational model is not a complete account of consciousness, karma, or liberation, and contemporary cognitive science has unresolved disputes about consciousness and agency. It does not “prove Buddhism.” The analogy simply helps expose how experiences that feel spontaneous may be assembled by conditions.

The practical test is therefore not whether one can label an experience “conditioned” or “unconditioned.” It is whether seeing conditionality reduces appropriation: less “this fear is me,” less “this praise guarantees me,” less “this person must complete me,” less “this thought must be obeyed.” The path uses conditioned practices to bring compulsive conditioning to an end.

Why contemporary people need it

Contemporary culture trains us to treat every problem as a production problem: optimize the schedule, engineer the mood, curate the identity, upgrade the body, grow the audience, manage the relationship, produce a better self. Much of this is useful. Food must be prepared, medicine developed, children educated, and institutions repaired. Buddhism does not deny ordinary causality.

The difficulty begins when we expect something conditioned to provide unconditional security.

A career can support a life but cannot become an unchanging foundation of identity. Approval can be pleasant but cannot permanently settle the question of personal worth. A partner can offer profound companionship but cannot abolish impermanence. Meditation can cultivate clarity and balance but, when grasped as an achievement, can become another unstable possession. Even a spiritual identity—“I am advanced, detached, awakened, or pure”—is fabricated and vulnerable.

無為 introduces a different axis. Liberation is not the final successful edition of the self. It is the ending of the greed, hatred, and delusion through which the self continuously tries to secure itself by appropriation.

This is why the term can initially feel threatening. The modern imagination often understands only two possibilities: constant productivity or collapse; self-improvement or resignation; control or helplessness. The unconditioned is neither. It does not recommend abandoning skillful effort. The early texts explicitly prescribe the Eightfold Path, heedfulness, mindfulness of breathing and body, good friendship, generosity, ethical conduct, and meditation. These are deliberate practices.

The paradox is that wholesome cultivation is used to end compulsive fabrication. One makes effort, but not to manufacture an eternal ego. One develops concentration, but does not mistake the resulting state for an immortal refuge. One practices wisdom until even attachment to “my wisdom” can be relinquished.

This is also why 無為 matters politically and relationally. Without the Mahāyāna qualification, people may interpret liberation as private insulation: “I am at peace; the suffering of others is conditioned and therefore unreal.” The *Vimalakīrti Sūtra* blocks that escape. “Not exhausting the conditioned” means remaining available within the difficult world of bodies, responsibilities, historical harms, and social institutions. “Not abiding in the unconditioned” means not using transcendence as a hiding place. At the same time, “not exhausting” the conditioned does not mean endorsing saṃsāric confusion. The bodhisattva participates without being possessed by participation.

This gives contemporary action a distinctive texture: work intensely without imagining that the result can be permanently secured; love deeply without converting another person into property; oppose harm without feeding hatred as one’s identity; rest without making numbness into liberation; use technology without surrendering the mind to every engineered impulse.

無為 also protects practice from despair. If liberation were a conditioned mood, it would always be at the mercy of the next unpleasant event. If nirvāṇa were manufactured, it would eventually disintegrate. The classical claim that it is unconditioned expresses the radicality of release: the exhaustion of bondage is not merely a temporary rearrangement of bondage.

Prajñāpāramitā and Madhyamaka then protect this hope from hardening into dogma. We must not imagine “the Unconditioned” as an invisible substance possessed by saints. The word performs liberating work only when it loosens grasping—including grasping at the word itself.

Common misunderstandings and clarifications

1. “無為 means doing nothing.”

No. This confusion is reinforced by the ordinary Chinese appearance of the term and by comparison with Daoist 無為, but the Buddhist technical term asaṃskṛta means “unconditioned,” not laziness or behavioral inactivity. The Eightfold Path, generosity, ethical discipline, meditation, and compassionate service all involve intentional cultivation. They are conditioned means directed toward the ending of affliction.

Chan descriptions of the “unconditioned” or the “person of no affairs” likewise do not commend neglect. They point to action free from contrivance and attachment. A person may be externally busy while inwardly not manufacturing identity from every action; another may sit motionless while greed and fantasy remain extremely busy.

2. “Any peaceful state is the unconditioned.”

No. Relaxation, absorption, emotional regulation, and the quiet produced by favorable circumstances are conditioned. The classical criterion is not intensity of peace but freedom from arising, abiding, alteration, and cessation. In the path-centered definition, 無為 is the exhaustion of greed, hatred, delusion, and all afflictions—not their temporary dormancy.

3. “The unconditioned is an eternal soul or cosmic consciousness.”

That conclusion is precisely what the Prajñāpāramitā, Yogācāra, and Madhyamaka warnings prevent. 無為 is not licensed as a permanent ātman hidden behind changing experience. The *Cheng Weishi Lun* refuses to establish the unconditioned as a separate, fixed entity outside mental and physical phenomena; its classifications are provisionally established in dependence on suchness. Madhyamaka says that conditioned and unconditioned are empty of self-established nature.

Words such as “constant” or “permanent” in scholastic descriptions therefore need care. They negate temporal production and destruction; they should not automatically be converted into the positive image of an everlasting substance.

4. “If the unconditioned is not produced, practice is unnecessary.”

This confuses manufacturing with realization. In the Abhidharma account of 擇滅, the path does not cause an unconditioned object to come into existence. Discernment removes bondage and makes liberation realizable. A limited analogy is opening one’s clenched hand: the opening does not manufacture the space that was supposedly trapped inside the fist. But even this remains an analogy, because bodily opening is itself conditioned.

The early discourses are unambiguous about the need for a path. Heedfulness, ethical conduct, right view, mindfulness, concentration, and wisdom matter because ignorance and craving do not disappear merely through verbal admiration of nirvāṇa.

5. “Every non-event is nirvāṇa.”

No. This erases the distinction between 擇滅 and 非擇滅. Something may fail to arise simply because its conditions are missing. A person may not become angry because no provocation occurred, may not drink because alcohol was unavailable, or may avoid envy by leaving social media. These absences can be skillful and protective, but they do not by themselves prove that the corresponding affliction has been uprooted through wisdom.

6. “Space is the unconditioned, so outer space is nirvāṇa.”

No. In the *Abhidharmakośa* classification, 虛空 is defined by non-obstruction. It is not straightforwardly identical with measurable physical space, the atmosphere, the night sky, or the astronomical universe. Nor are the three unconditioned dharmas simply three synonyms for nirvāṇa. Analytical cessation has the direct liberating significance of disconnection from defilement; the categories retain distinct definitions.

7. “All Buddhist schools teach exactly the same list of unconditioned dharmas.”

They do not. The *Abhidharmakośa* gives three; the *Yogācārabhūmi* gives eight; the *Treatise on the Hundred Dharmas* gives six; the *Cheng Weishi Lun* discusses five and explains them as provisionally established on the basis of suchness. These systems should be compared without flattening their internal purposes or silently replacing one list with another.

8. “Because Madhyamaka says the unconditioned is empty or ‘only a name,’ liberation is unreal.”

That is a nihilistic misreading. “Only a name” denies independent self-nature, not the pragmatic and liberating significance of cessation. Medicine, illness, and recovery are also dependently designated; this does not make treatment pointless. Madhyamaka prevents us from taking the conceptual opposite of conditioned existence and converting it into an absolute entity.

The *Twelve-Gate Treatise* therefore says both conditioned and unconditioned are empty. It does not say that greed and freedom from greed are ethically indistinguishable, or that practice has no consequence.

9. “Nirvāṇa and 無為 can always be substituted word for word.”

They are very closely related and many scriptures use 無為 for nirvāṇa or the extinction of afflictions. The *Dhammapada* translation known as the *Faju Jing* (《法句經》) uses the older transliteration 泥洹 (níhuán) for nirvāṇa and says “無為得泥洹.” But technical classifications may give 無為 a broader extension: the *Abhidharmakośa*, for example, includes space and non-analytical cessation alongside analytical cessation. Conversely, the *Ratnakūṭa* says that in the nirvāṇa-element, which exceeds all discrimination, even the name “unconditioned” is absent. Context determines the force of the term.

10. “A bodhisattva should reject the unconditioned and remain in worldly activity.”

The *Vimalakīrti Sūtra* says neither this nor its opposite. “Not exhausting the conditioned, not abiding in the unconditioned” is a double discipline. Without wisdom, activity becomes bondage. Without compassion, peace becomes a private refuge. The bodhisattva realizes non-attachment while continuing to respond to suffering.

The deepest function of 無為 is thus not to provide one more object for the mind to possess. It reveals the limit of the entire project of possession. At first, the distinction between conditioned and unconditioned teaches us where lasting refuge cannot be found. The path then exposes and exhausts the greed, hatred, and delusion that keep demanding such refuge from impermanent things. Finally, wisdom releases even the distinction itself: no clinging to saṃsāra, no residence constructed in nirvāṇa, and no identity built from being the one who has transcended both.

That is why 無為 is both the promise of the path and a test of our understanding. If it makes us passive, grandiose, metaphysically possessive, or indifferent to suffering, we have turned it back into fabrication. If it helps us act carefully without clinging, meet change without demanding that it become permanent, and care for beings without using them to secure a self, then the word is beginning to perform its liberating work.

一、定义与核心要义

无为(asaṃskṛta),意为非由因缘造作、不经生住异灭之常住法,与「有为」之生住异灭相对而立。其基本界定为「不生、不住、不灭」,并与「涅槃」「真如」「实际」「法性」「如」「虚空」「择灭」「非择灭」等概念密切关联。

二、主要阐述

阿含部:《杂阿含经》明有为「若生、若住、若异、若灭」,无为「不生、不住、不异、不灭」,以「贪欲永尽、瞋恚、愚痴永尽、一切烦恼永尽」为无为法之体,以八圣道为趣向无为之「无为道迹」。《增壹阿含经》惯用「至无为处」,将无为表述为修行所趋至之安隐境地,并与涅槃紧接并举。

般若部:《摩诃般若波罗蜜经》界定无为法为「不生不住不灭」,列「染尽、瞋尽、痴尽,如、不异、法相、法性、法位、实际」为其内容;然于胜义中,「有为性、无为性不合不散」,皆归「一相所谓无相」。

宝积部:《大宝积经》以「无生、无灭、无住」三相永离界定无为,并独特提出「涅槃界中超过一切动念分别,尚无无为,况有有为」之破执语。

本缘部:《法句经》以「泥洹」指究竟果位,谓「无为得泥洹」。

经集部:《佛说弥勒下生经》仅以「必至无为处」一句总收归趣。《维摩诘所说经》提出「不尽有为,不住无为」之菩萨双行。

毘昙部:《阿毘达磨俱舍论》明列三无为:虚空、择灭、非择灭。

释经论部:《大智度论》以「有为法实相即是无为」为核心表述,并举虚空、数缘尽、非数缘尽三种无为。

瑜伽部:《瑜伽师地论》立八种无为,包含虚空、非择灭、择灭、善、不善、无记法真如、不动、想受灭。《成唯识论》列五种无为,皆依真如假立。《大乘百法明门论》列六种无为。

中观部:《中论》以破有为三相为前提,逼显「无为法但有名字」之结论。《十二门论》则云「有为法空故无为法亦空」。

诸宗部:《黄檗断际禅师宛陵录》谓「心既无为,法亦无为」。《黄檗山断际禅师传心法要》以「绝学无为闲道人」为标帜。

三、不同部类与译本的表述差异

1. 「涅槃」之译名:《法句经》作「泥洹」,其余各经多作「涅槃」。 2. 「五蕴」之译名:《法句经》与《十二门论》用「五阴」;《阿毘达磨俱舍论》固定使用「蕴」;其余各经多用「五蕴」。 3. 无为之分类:《大智度论》用「数缘尽、非数缘尽」;《俱舍论》用「择灭、非择灭」;《大乘百法明门论》用「不动灭无为、想受灭无为、真如无为」六种;《瑜伽师地论》立八种。 4. 「至无为处」之语式:《增壹阿含经》惯用「至无为处」、「安处无为」、「独处无为」等趋向式表述。 5. 禅宗之表述:黄檗系禅师以「心」、「虚空」、「菩提」为无为之异名同指,未沿用「不生不灭」之分析式语汇。

四、与相关概念的关系

无为与「有为」对举,有为有生住异灭,无为无此诸相。无为与「涅槃」关系密切,多经以涅槃即无为之异名,惟《大宝积经》谓涅槃界中尚无无为之名。无为亦与「真如」、「实际」、「法性」、「如」相通,《摩诃般若波罗蜜经》列「如、不异、法相、法性、法位、实际」于无为法中。「虚空」在《俱舍论》中为三无为之一,而《成唯识论》明「此五皆依真如假立」。此外,无为亦常与「有漏/无漏」、「世间/出世间」、「染/净」等对偶并列。

五、代表性原文引用

1. 《杂阿含经》:「不生、不住、不异、不灭」即无为。 2. 《摩诃般若波罗蜜经》:无为法为「不生不住不灭」。 3. 《大宝积经》:「言无为者无生无灭亦无有住,三相永离故名无为」。 4. 《法句经》:「无为得泥洹」。 5. 《维摩诘所说经》:「不尽有为,不住无为」。 6. 《阿毘达磨俱舍论》:三无为为「虚空、择灭、非择灭」。 7. 《成唯识论》:「此五皆依真如假立」。 8. 《大乘百法明门论》:「虚空无为、择灭无为、非择灭无为、不动灭无为、想受灭无为、真如无为」。 9. 《中论》:「无为法但有名字」。 10. 《黄檗断际禅师宛陵录》:「心既无为,法亦无为」。

維摩詰所說經T0475 · 經集部

本部《維摩詰所說經》對「無為」之闡述,可從三個層面歸納。

一、以「出家」明「無為」之體性。維摩詰對羅睺羅說:「有為法者,可說有利、有功德。夫出家者,為無為法,無為法中,無利、無功德。」此處以「有為」對顯「無為」,明示無為法超越福德計度,非因緣造作之生滅法所能涵攝。復云:「出家者,無彼無此,亦無中間;離六十二見,處於涅槃。」此以「無彼無此」之雙遮、「處於涅槃」之正顯,標舉無為之寂滅性。

二、以「法」之九喻顯「無為」之超越相。維摩詰告舍利弗,云「法名無為,若行有為,是求有為,非求法也」;此與同段「法名寂滅,若行生滅,是求生滅」、「法名無相,若隨相識,是則求相」、「法不可住,若住於法,是則住法」、「法不可見、聞、覺、知」等並列,以「名」字揭示法之本性皆為遮遣之詮:法本寂滅、無染、無行處、無取捨、無處所、無相、不可住、不可見聞覺知、亦名無為。換言之,此經以「法名無為」一語,總攝一切戲論之否定——凡有所行、有所住、有所求,皆是「有為」之求,而非真實之求法。當機五百天子因此得法眼淨。

三、以「盡無盡解脫法門」明菩薩對「無為」之不共行。此法門先辨二相:「何謂有為?……何謂無盡?謂無為法。」繼而揭示菩薩之正修為「不盡有為,不住無為」,雙遮雙照,迥異二乘滯於涅槃之偏。後文更具體云:「集法藥故,不住無為;隨授藥故,不盡有為。知眾生病故,不住無為;滅眾生病故,不盡有為。」菩薩不住無為,方能集法藥以度眾;不盡有為,方能隨緣赴感以救世。是故此經不以「無為」為究竟之歸趨,而以「不盡有為、不住無為」之雙行為大乘解脫之門。

綜合言之,本經論「無為」所用術語,逕用「無為」、「有為」、「法」等通名,未見異名異稱。其獨特側面有三:其一,以「無利無功德」否定福德門;其二,以「法名無為」之遮詮,統攝法之九喻——寂滅、無染、無行處、無取捨、無處所、無相、不可住、不可見聞覺知、無為;其三,強調菩薩對無為「不住」之立場,區別於二乘之取證涅槃。

一、法義對比層面:經中以「有為」與「無為」並舉,界定二者之差異。有為者乃「若生、若住、若異、若滅」,無為者則「不生、不住、不異、不滅」,明示無為是不由因緣造作生滅之法。經文進一步將無為等同於涅槃,稱「一切取離、愛盡、無欲、寂滅、涅槃」即名「諸行苦寂滅涅槃」,亦即「有為、無為」二法中的無為。此外,經中亦指出,於一切有為、無為法中,「離貪欲法最為第一」。

二、修道實踐層面:經中專門說明「無為法」與「無為道跡」。所謂無為法者,即「貪欲永盡,瞋恚、愚癡永盡,一切煩惱永盡」;所謂無為道跡者,即「八聖道分:正見、正智、正語、正業、正命、正方便、正念、正定」。此處以八正道為趣向無為之途徑,並於經末附列「難見、不動、不屈、不死、無漏、覆蔭、洲渚、濟渡、依止、擁護、不流轉、離熾焰、離燒然、流通、清涼、微妙、安隱、無病、無所有、涅槃」等異名,皆與無為同義而說。

三、詩頌層面:經中多處以「無為」形容出離之樂。諸如「獨善無為樂」、「唯無為為樂,言則定善言,不言則寂定」;又有諸天反覆請問「不起處」、「無為安隱樂」,如「若有不起處,無為安隱樂,得如是處者,無作亦無憂」,疊以「無作亦無憂」為無為之勝義,並以「方便」與「不放逸」為得此樂之因,最後歸結「無事亦得樂,無作亦無憂」。此中「無為安隱樂」即契合於無為不生不滅之寂滅相。

總結:《雜阿含經》以「無為」一詞涵攝三義:一為對有為生滅之否定,即不生、不住、不異、不滅;二為一切煩惱永盡之涅槃境界;三為八正道所趣向之寂滅安隱。其術語以「無為」為主體,並與「涅槃」「寂滅」「愛盡」「無欲」「無作」「不起」等詞並用,未見其他異譯之替名。

《增壹阿含經》論「無為」,最常用的語式是「至無為處」或「至無為之處」,把無為表述為修行所趨至的安隱、滅度境地;另見「無為道」、「無為之境」、「無為涅槃界」等形式。經中亦將「有為法、無為法」並列,顯示「無為」不只用作目的地式的譬喻,也作為法的類別名稱。

無為與涅槃關係密切。經文屢以「至無為處」緊接「自致涅槃」,又稱「涅槃無為處」及「無為涅槃界」。馬血天子所述「無為之境」,具有「無生、無老、無病、無死、無終、無始,亦無愁、憂、苦、惱」的特徵,並由此聯想到涅槃;這是本經對無為之不生滅、離眾苦側面的集中表述。

本經特別著重通往無為的實踐途徑。念施、念天、念休息、念安般與念身,皆被說為能成大果報、得甘露味、除亂想、獲沙門果而至無為處;其中念休息重在息滅心意妄想、專一閑居、入三昧定,念安般重在明察出入息,念身則觀察身分、四大及身之來源歸趣。

此外,八品聖道被譬為舟船,能究竟「世界邊」而至無為;船筏譬喻又以此岸為恐難、彼岸為無為,說依筏度至彼岸後,善法尚應捨離,何況非法。經文並以滅除憍慢、慈心遍滿諸方、離惱亂想,說明長夜獲得無為之處的修行方向。

無放逸是另一核心條件。聖弟子以「無放逸力」勝過魔之色、聲、香、味、細滑五力,因而不受五欲拘繫,能分別生、老、病、死而至無為;又明言「涅槃者以無放逸為食,乘無放逸,得至於無為」。親近善知識則被稱為「全梵行」,能增益信、聞、念、施、慧,並引導善道以至無為。

本經亦從障礙面反說無為:染著財物、貪受利養、婬欲、飲酒及貪欲,皆令人不能至無為;利養之害尤被反覆申說,甚至能使修頭陀行者退失法衣、還俗造惡。相對而言,修不淨想以除欲與亂想、護持身口意三種善行、行慈與不害,皆可趨向無為。

就用詞而言,《增壹阿含經》並未只用抽象的「無為法」,而更慣用帶有趨向意味的「至無為處」;又有「渡四流無為」、「安處無為」、「獨處無為」等依語境而異的表達,其中「獨處無為」描述閑靜獨處,不宜逕與作為滅度目標的「無為處」完全等同。
