What This Concept Is Saying

In classical Buddhist thought, conditioned phenomena (有為法 *saṃskṛta-dharma* — things that arise from causes and conditions) are said to bear three marks or characteristics (三相): arising (生相 *utpāda-lakṣaṇa*), abiding (住相 *sthiti-lakṣaṇa*), and cessation (滅相 *nirodha-lakṣaṇa*). These are the most familiar features of impermanence — things come into being, stay for a moment, and pass away. 滅相 names the third of these: the apparent "characteristic of fading, decline, disappearance, or dissolution" that conditioned things exhibit.

So far, this is the conventional (世俗 *saṃvṛti*) teaching. Almost every school of Buddhism accepts this as a working description. The Buddha himself pointed out impermanence again and again — in the *Dhammapada*, in the *Saṃyutta Nikāya*, in countless places — and most practitioners never question whether the three marks are real, separate properties.

But **the *Mūlamadhyamakakārikā* (《中論》, "Fundamental Verses of the Middle Way," T1564), the foundational śāstra of the Madhyamaka school attributed to Nāgārjuna, takes an unusual step: it does not stop at affirming the three marks, but interrogates whether any of them — and especially 滅相 — can be established as a determinate, independent, self-existing characteristic.** This is what makes the concept philosophically charged. It is not just "things end." It is: *can "ending" be pinned down as a real property anywhere?*

The argument is intricate but can be unfolded in six moves, each of which chips away at the assumption that cessation is a stable, findable feature of phenomena.

1. The three-time analysis (三時推求). When something has *already* ceased, you cannot say it is ceasing — it has finished. When it has *not yet* ceased, you cannot say it is ceasing — the mark of cessation is not there. And is there some third moment, a "time of ceasing" (滅時), in which cessation is actually occurring? In this third time, the thing would either already be past-ceased or not-yet-ceased; no independent, third moment can be located. So cessation cannot be pinned to any moment: 「法已滅不滅,未滅亦不滅,滅時亦不滅,無生何有滅?」 (What has already ceased does not (need to) cease; what has not yet ceased also does not cease; the time of ceasing itself does not cease — if there is no arising, how could there be cessation?) The conclusion drawn is 「滅法即是無生,無生何有滅」 — "the cessation of dharmas is precisely no-arising; if there is no arising, how could there be cessation?"

2. Cessation contradicts arising. A single dharma, at a single moment, cannot simultaneously possess the mark of arising and the mark of cessation — these are opposite. 「若諸法滅時,是時不應生」 — "If a dharma is at the moment of cessation, it should not at that time be arising." On the other hand, you cannot retreat to a "never-ceasing dharma" (不滅法), because all conditioned dharmas are ceasing moment by moment, and apart from conditioned dharmas there is no independently established "unconditioned cessation-free dharma." So both horns fail.

3. Cessation contradicts abiding. A dharma with the mark of cessation cannot at the same time bear the mark of abiding (住). 「若法滅相,是法無有住相」 — "If a dharma has the mark of cessation, it has no mark of abiding." But the converse is also unstable: a dharma that is abiding (and thus, by its abiding, not ceasing) cannot be ceasing; and a dharma that is "not-abiding" — if that means it has no dharma-essence at all — cannot have anything to cease. The two cannot be held simultaneously, but neither can be cleanly severed from the other.

4. Cessation cannot be self-caused or other-caused. Just as a dharma does not arise from itself or from another (the well-known refutation of 自生/他生), so it cannot *cease* from itself or from another: 「法不自相滅,他相亦不滅」 — "A dharma does not cease by its own mark; it does not cease by another mark." The milk simile illustrates this precisely: while milk is genuinely milk, the milk-character is present and not yet lost — so we cannot say the milk is ceasing in that moment. Once it is no longer milk (curdled, soured, gone), there is no longer a "milk" for cessation to belong to. No determinate mark of milk-ceasing can be located.

5. From the angles of being and non-being, cessation cannot be established. If a dharma is presently *being* (有), then it cannot simultaneously possess the mark of *non-being* (無); 「若法是有者,是即無有滅;不應於一法,而有有無相」 — "If a dharma is, then it has no cessation; one and the same dharma should not have the marks of being and non-being together." If a dharma is *non-being* (like a second head or a third hand), it has never been, so it cannot be "cut off" — it has no cessation-marker because there is nothing there to cease. The pot simile makes this vivid: a pot in its pot-condition has no break-down-character; a no-pot moment has no pot's break-down-character either. So between existence and non-existence, no determinate cessation can be caught.

6. The culmination: no arising, therefore no cessation. Once the mark of arising is seen to be unestablishable (the famous "諸法無生" / *anutpāda* doctrine of Madhyamaka), cessation follows it: 「如一切諸法,生相不可得;以無生相故,即亦無滅相」 — "Just as for all dharmas the mark of arising cannot be obtained, so because there is no mark of arising, there is also no mark of cessation." And the *Mūlamadhyamakakārikā* closes this section with the ringing summary: 「諸法從本已來無生,畢竟寂滅相」 — "All dharmas, from the very beginning, have no arising; they are, in the end, characterized by ultimate quiescence (寂滅相)."

This last line is important and easily missed. The "寂滅相" (the mark of ultimate peace / *śāntatā-lakṣaṇa*) here is not a third or fourth mark added on. It is what remains when the unestablishable three marks are seen through. It is the *nirvāṇa*-side of the same teaching. The whole trajectory is: things do not genuinely arise, therefore they do not genuinely cease; the apparent beginningless coming-and-going of phenomena is itself, when looked into, this primordial quiescence.

There is also an explicit warning against two extreme misreadings of cessation. To imagine that things first determinately exist and then later completely break down into nothing is to fall into 斷滅見 (*uccheda-dṛṣṭi*, the nihilistic view of total annihilation). To imagine that things have a fixed nature that ought never to become non-existent is to fall into 常見 (*śāśvata-dṛṣṭi*, the eternalistic view of permanent being). Both are rejected.

The relation to the other marks is structurally important: 滅相 cannot be understood on its own. It is a member of a triad with 生相 and 住相, and the argument uses the mutual exclusion among all three. Cessation also relates directly to 無生 (*anutpāda*, "no-arising") and 寂滅 (śāntatā, "quiescence") — these are not different topics but different faces of one insight. The Buddhist *Heart Sūtra* (《般若波羅蜜多心經》) — famous even to non-Buddhists as "色不異空,空不異色;照見五蘊皆空" — expresses the same insight in a different idiom: when the five aggregates are seen through, neither arising nor cessation stand as independent marks.


Life Investigation: Walking Through 滅相 in the Present Moment

It is one thing to read the *Mūlamadhyamakakārikā*'s syllogisms. It is another to notice where 滅相 actually shows up in your experience, and where its unestablishability can be observed. Let us walk through several ordinary scenes, mapping the classical moves onto lived experience, and flagging where the popular mapping tends to go wrong.

Scene 1: The end of a long relationship. You come home and the other person is gone. The furniture is the same; the apartment is the same; but something has ended. In conventional talk: "the relationship has ceased." This is the most familiar surface meaning of 滅相. The classical analysis asks: *when exactly did it cease?* Was it last night's argument? Was it six months ago when trust frayed? Was it the moment of the actual departure? You will not find a clean moment of cessation. You will find a slow, mutually-conditioning cascade. (This is the three-time analysis: the "already-ceased" is hard to identify because there is no sharp boundary; the "not-yet-ceased" was indistinguishable from earlier moments; the "currently-ceasing" moment cannot be located as a third, independent instant.)

Scene 2: The fading of attention while scrolling. You start to read an article. By paragraph three, attention has dissolved. You scroll. You start a video. By minute two, the thread is gone. There is a sense of "the reading/attention has ceased." But notice — when, exactly? At no single point did the article disappear from the screen, and at no single point did "you" decisively stop reading. The cessation is woven through. The common mapping error: most people mistake this kind of fading for a simple "loss of willpower" or a "decision to stop." The classical teaching asks you to look more closely — the loss has no fixed mark; it has no self-causation (you cannot find a "you" that owns the fading), no other-causation (the article's words did not issue a cease-order), and no determinate moment. (This is the self/other cessation analysis with the milk simile: while there is a stream of reading, reading-character is present; once reading has gone, there is no reading there to "cease.")

Scene 3: Watching a wave break. You are at the ocean. A wave rises, crests, breaks, dissolves into foam. Conventional language: "the wave has ceased." The classical analysis presses: was the wave the same wave that ceased? Where is the moment the wave is no longer the wave — at the crest, at the foam, at the flat water? Each moment is a different configuration. The cessation has no determinate owner. (This is the being/non-being analysis: the wave-as-wave is not there at the moment of foam; the foam-as-foam is not there at the moment of crest. Neither contains a "wave-ceasing" mark.)

Scene 4: The death of a parent. Here 滅相 is most painful and most acute. The classical analysis is not a denial of grief, nor a refusal to say "they have died." It is a deeper probe: *what exactly has ceased?* The body? Yes, but in what sense was the body a fixed entity to begin with? The relationship? But the relationship was already a stream of conditions, each moment partially new. The future that was expected? That future never existed in the determinate way it seemed to. The culminating move (no arising → no cessation) does not deny the loss; it observes that the entity "parent" was always a provisional designation on a stream of conditions — and so the "loss of parent" is itself a provisional designation. (This is sometimes heard as cold, but in classical Madhyamaka it is the very basis for a liberated response to loss — one that can grieve without being shattered by a phantom of permanent existence collapsing into a phantom of permanent nothingness.)

Scene 5: The end of an identity. You were a particular kind of professional, parent, citizen, friend. A diagnosis, a layoff, a divorce, a political upheaval, an aging body, and the identity dissolves. Conventional speech: "I am no longer the person I was." Classical analysis: *which "I" was there in the first place as a determinate entity to be no-longer?* The narrative you built — "the one who used to be able to…" — was always a story assigned to a stream. The "no longer" has no fixed mark. (This is the abiding/cessation contradiction: you cannot simultaneously have a stable abiding-identity and a now-ceased identity.)

Where most contemporary readers go wrong in the mapping. There are several predictable errors:

- Mistaking 滅相 for "ending" as an event. In common usage, "ending" is treated as a discrete event (the breakup, the death, the layoff). The classical analysis deliberately resists this; it shows that what looks like an event is really an unfindable seam in a continuum. The point is not that nothing happens, but that no determinate *mark* of cessation can be pinned down. - Mistaking it for nihilism (斷滅). "If nothing truly ceases, then nothing matters." This is the very view the *Mūlamadhyamakakārikā* warns against. Not finding a determinate mark of cessation is not the same as denying all change; it is denying that change can be captured by a self-existing property called "cessation." - Mistaking it for "eternalism" (常見). On the other side: "If cessation cannot be found, then things never really end." Also rejected. The point is that the dissolution of conditioned things is undeniable in conventional terms; what is denied is that "dissolution" exists as a real, findable characteristic over and above the stream of conditions. - Confusing 滅相 with 涅槃. Many readers encounter Buddhist teaching about "cessation" and assume it points to nirvāṇa as a kind of "final stopping." 滅相 in this Madhyamaka context is a *characteristic of conditioned phenomena that cannot be found as a self-existing property*. The teaching points instead to 寂滅相 (*śāntatā-lakṣaṇa*) — the *unfindability* of any of the three marks is itself the doorway to nirvāṇa-like understanding. This is a subtle but consequential distinction.


Why Contemporary People Need This

Why bother with such an intricate philosophical analysis of a single "mark" of phenomena? There are several reasons, and they are not just academic.

1. We live inside a culture addicted to "ends." Stories, news cycles, careers, romantic arcs, even meditation apps — contemporary life is organized around beginnings, climaxes, and endings. The implicit assumption is that ends are discrete, identifiable events: the divorce happened on a date; the career ended at a moment; the friendship broke at a phone call. The classical analysis loosens this grip. It does not deny that change occurs, but it shows that *the way we conceptualize change* — as a sequence of findable endpoints — is itself a constructed overlay, not a feature of reality. Loosening this overlay tends to bring a measure of ease to people who feel perpetually punched by "endings."

2. It addresses our split between nihilism and eternalism in the face of loss. Modern psychology and culture oscillate between two unhelpful poles. On one side, when something ends, there is often a collapse into 斷滅 — "everything is over, nothing remains, the world is meaningless." On the other side, there is often a desperate grasping toward 常見 — "this should not have ended, the universe is broken, things should be permanent." The Madhyamaka analysis of 滅相 offers a third stance: the *unfindability* of cessation as a determinate mark does not require either despair or denial. It is closer to what some contemporary contemplative writers (without using these terms) call "allowing things to be as they are."

3. It complements, without being reduced to, contemporary science. Modern physics and biology have taught us that what looks like solid, bounded things are in fact processes — a person is a turbulent stream of atoms, a thought is a transient pattern of neural activity, an ecosystem is a web of relations. The Madhyamaka analysis of 滅相 is *consistent* with such pictures but goes further: even the *process* of change is not reducible to a real, self-existing property called "cessation." Where contemporary science describes the *mechanisms* of transformation (and remains silent or divergent about the *ultimate status* of change itself), the Buddhist analysis interrogates the conceptual overlay. The point is *not* that "quantum physics proves Madhyamaka" — that would be a category mistake. The point is that the Buddhist analysis addresses a layer (the metaphysics of characteristics) that contemporary empirical science, by design, does not address.

4. It is a doorway to a different way of living with impermanence. Most Buddhist and contemplative practice around impermanence (無常 *anitya*) urges us to *notice* change. The Madhyamaka analysis of 滅相 urges us to notice that *even change as a self-existing property* cannot ultimately be located. This is a deeper cut. It does not produce a special experience; rather, it tends to soften the tendency to grasp or resist the very structure of arising-and-ceasing. For practitioners tired of devotional or feel-good spirituality, this is a rigor that still matters.


Common Misreadings and Clarifications

A few final clarifications — because this concept has unusual potential for being flattened into something simpler than it is.

Misreading 1: 滅相 means "things end," and that's the whole point. Clarification: in the Madhyamaka framing, *the whole point is that "things end" cannot be cashed out as a determinate mark*. The teaching is not a confirmation of impermanence; it is an interrogation of how impermanence is conceptualized. Beginners sometimes think Madhyamaka is "extra-deep impermanence teaching." It is, more precisely, an *unmaking* of how impermanence is conceptualized as a property.

Misreading 2: Since cessation cannot be found, nothing actually changes. Clarification: this is the 斷滅 (nihilism) the text explicitly warns against. The teaching does not deny that conditioned dharmas appear to come and go in conventional terms. It denies that *cessation* can be grasped as a self-existing mark over and above the appearing-and-disappearing. To say "cessation cannot be found as a determinate mark" is not the same as saying "nothing ceases."

Misreading 3: Since cessation cannot be found, things never really end — and that is comforting. Clarification: this is the 常見 (eternalism) the text also warns against. The unfindability of cessation is not a metaphysical promise that the things you love will persist. It is an observation about the structure of *how* ending appears.

Misreading 4: 滅相 is just another word for 涅槃. Clarification: they are related but not the same. 滅相 is a mark *of conditioned phenomena* that the analysis shows cannot be established. 涅槃 (*nirvāṇa*) — and its associated 寂滅相 (*śāntatā-lakṣaṇa*) — names the unconditioned (無為法 *asaṃskṛta-dharma*), the "ultimate quiescence" that is *not* a third property but the very dimension opened when the three marks are seen through. The trajectory of the *Mūlamadhyamakakārikā* moves from the unfindability of 滅相 to the affirmation of 寂滅相 as the mark of all dharmas from the beginning: 「諸法從本已來無生,畢竟寂滅相」. Reading 滅相 as 涅槃 flattens a critical transition.

Misreading 5: The Madhyamaka analysis is purely abstract and has no practical relevance. Clarification: the practical relevance is precisely the softening of grasping at endpoints that characterizes much of contemporary suffering. The analysis is not an exercise to be admired from afar; it is a reframing of how phenomena are experienced. When the mark of cessation cannot be found as a self-existing property, the grip of "this should not have ended" and "this has ended forever" both loosen, not into indifference but into a more spacious relationship with change.


Where This Concept Sits in the Path

In the classical Indian Buddhist framework, this analysis belongs to the *prajñā* (般若 / wisdom) wing of the path — specifically to the Madhyamaka (中觀) school of philosophical training. It does not belong to the *sīla* (moral discipline) or *samādhi* (concentration) trainings, though it is meant to clarify what those trainings are doing. The unfindability of 滅相 is one piece of a much larger analysis that also covers the unfindability of 生相 (arising), 住相 (abiding), and the various *skandhas* (aggregates), *dhātus* (elements), and *āyatanas* (sense bases). In the *Heart Sūtra*'s compressed formula — "照見五蘊皆空,度一切苦厄" ("having seen the five aggregates as empty, one crosses all suffering") — the empty-seeing of any one of the five aggregates already touches this entire network, including 滅相.

The point of the analysis is not to produce an intellectual victory but to *wear down* the subtle assumption that phenomena possess findable, self-existing characteristics — beginning, middle, and end. When that assumption is examined, something in the mind relaxes: not because reality has been proven to be a certain way, but because the overlay of "things have determinate marks" has been seen to be exactly that, an overlay. That relaxation is, classically, what allows both compassionate action in the world and freedom from the compulsive reactivity that the overlay produces.

In short: 滅相 is the apparent "ending-mark" of conditioned things. The Madhyamaka analysis shows that this mark cannot be located as a real, determinate, self-existing property — not by time, not by relation to arising or abiding, not by self or other, not by being or non-being. From this, "no arising, no cessation" (無生無滅) emerges; and from that, the affirmation that all dharmas are characterized, from the very beginning, by ultimate quiescence (畢竟寂滅相). The contemporary relevance is not in adding another doctrine but in loosening a deep habit of mind: the habit of treating ends as real, findable, and devastating — or as real, findable, and consoling. The teaching points to a place where neither grip is needed.

Canonical EntryAI-generated

1. 定义与核心要义

「灭相」(nirodha-lakṣaṇa)指有为法衰灭、失坏或消失之相状。《中论》先依通行说法,将灭与生、住并列为有为法三相,说「有为法有三相:生、住、灭」,又以「生住灭是有为相,无生住灭是无为相」区分有为与无为。但其论述重点不在建立一个具有决定实体的灭相,而是追问:生、住、灭若自身是有为法,如何能为其他有为法作相;若是无为法,又如何能表征有为。两端推求皆有困难,因而显示灭相不可被执为独立、固定而实有的性质。

《中论》最终以「诸法从本已来无生,毕竟寂灭相」总摄其旨。此处「寂灭相」并非承认一个先实有、后消失的断灭过程,而是说诸法本无决定生起,故亦无决定灭去。

2. 主要阐述

首先,从已灭、未灭、正灭三时考察,灭相皆不可得。已灭之法早已灭去,不须也不能再次灭;未灭之法尚离灭相,不能说正在灭;在已灭与未灭之外,又找不到独立的「灭时」。故偈说:「法已灭不灭,未灭亦不灭,灭时亦不灭,无生何有灭?」论释遂归结为「灭法即是无生,无生何有灭」。

其次,灭与生相互违背。同一法于同一时不应兼具生、灭二相,所以「若诸法灭时,是时不应生」;然而若另立永不灭之法,也「终无有是事」。其理由是灭相之法不应同时生起,而一切有为法念念灭,离有为法亦无可被决定建立的「不灭法」。由此进一步说,一切法的生相既不可得,便「以无生相故,即亦无灭相」。

再次,灭与住亦相违。若一法已有灭相,便不能同时具有住相,故说「若法灭相,是法无有住相」。但从另一面推求,住法因有住相而不灭;不住法若被理解为离住相而全无其法,则无法可得,又不能说它灭。因此住与不住两端均不足以确立决定的灭相。

第四,灭不能由自相或他相成立。《中论》依自生、他生皆不可得的论式说:「法不自相灭,他相亦不灭」。乳的譬喻显示:正有乳时,乳相确定存在,不能就在乳相中说乳已灭;已非乳时,又没有乳法可作灭的承受者,因此两时均不能建立乳的决定灭相。

第五,从法的有、无两端观察,灭同样不能成立。若法是有,同一法中不应同时具有有相与无相,故说:「若法是有者,是即无有灭;不应于一法,而有有无相。」若法本来是无,如第二个头、第三只手,既从未存在,便无从断除,也不能具有灭相。瓶的譬喻亦说,瓶正在瓶相中时没有失坏相;无瓶之时也没有一个瓶的失坏相可得。生、灭彼此因待,灭既不可离法而成立,生亦不能独立确立。

最后,《中论》同时指出两种执取的后果:若认为法先决定实有,后来完全败坏而无,便落入断灭之见;若认为法性决定实有、终究不应成无,则执着常住的有相。二者皆被要求舍离。

3. 不同部类与译本的表述差异

本条所据材料仅见中观部《中论》(《中論》),未提供其他部类经论或《中论》异译本,故不能据此列出跨部类、同经异译的对应差异。就《中論》自身而言,核心名称为「灭相」;在不同论证语境中又使用「有为相」「寂灭相」「坏败」「失坏相」等词。「灭相」着重有为法灭去的相状;「有为相」将灭置于生、住、灭三相之中;「失坏相」「坏败」用于说明由存在转为败坏的主张;「寂灭相」则出现在「从本已来无生、毕竟寂灭」的总结中。材料未显示另有特殊异译名称。

4. 与相关概念的关系

灭相首先与「生相」「住相」共同构成有为三相,但三者又受到相互关系的检验:生与灭相违,住与灭亦不能一时一处并存。生灭又属相互因待的概念;若无生相,便无灭相,不能各自成为独立自存的性质。

灭相亦与「无生」「寂灭」直接相关。《中论》不是由实有之生建立实有之灭,而是由生相不可得说明灭相亦不可得,并以「毕竟寂灭相」表达诸法本来无生的结论。此外,若把灭理解为实有法转成全无,便涉及「断灭」;若否认一切灭而执法性恒有,则涉及「常见」。两种见解在本论中均不被确立。

5. 代表性原文引用

「法已灭不灭,未灭亦不灭,灭时亦不灭,无生何有灭?」

「如一切诸法,生相不可得;以无生相故,即亦无灭相。」

「若法是有者,是即无有灭;不应于一法,而有有无相。」

「法不自相灭,他相亦不灭。」

「诸法从本已来无生,毕竟寂灭相。」

大智度論T1509 · 釋經論部

《大智度論》論「滅相」之義,有數端須辨明:

其一,直陳滅相之體性。論中以偈頌明示:「滅者即是不可量,破壞因緣及名相,一切言語道已過,一時都盡如火滅。」此謂滅相超越語言、不可度量,能壞滅因緣與名相,猶如薪盡火滅,剎那歸於寂無。此乃以譬喻彰顯滅相之頓斷性。

其二,辨析滅相之定義。有人以「非智緣滅」為滅相,論主破之曰:「無常滅故,是名滅相,非以非智緣滅故名為滅相。」明確區分「非智緣盡」與「無常滅」二者,確立唯有無常之滅方為真滅相。此處顯示論主對滅相之界定乃依無常性而立,非依智之是否緣及。

其三,滅相與寂滅相、究竟相互通。論中言「涅槃是寂滅相」,菩薩以般若波羅蜜之力破壞五眾,通達令空,即是涅槃寂滅相。又一切種智有二種相,「一者、通達諸法實相故寂滅相」,如大海水深故波浪不起,戲論風所不能動。此以寂滅相形容證悟實相之安穩不動。又「色不滅即是色無依處」,究竟相中亦無分別,是諸法寂滅相之別名。

其四,滅相與無相之關聯。論主破斥定相之執時,言「無為法無相故實無」,又云「是法無相、無量,云何可得差別」。滅相既屬涅槃寂滅之理,則無定相可得、無量可測,故不可分別高下、有餘無餘。

其五,聖人不取滅相。論中明「聖人於諸法不取相亦不著,是故聖法為真實;凡夫於諸法取相亦著,故以凡夫人法為虛妄」。菩薩行般若波羅蜜時,不作「我當壞諸法相」之念,亦不念「心滅」之相,住「如如住」中,無所取著。

其六,滅相與五眼見之關係。論言「佛眼觀寂滅相故不應見」,五眼因緣和合而生,皆是作法、虛誑不實,故佛不以五眼見眾生心。

綜觀此論,滅相之核心在「無常滅故」,而非智緣之滅;其相與寂滅相、究竟相互通,皆顯諸法實相之無定相、無所得。論主以「破壞因緣及名相」、「如火滅」等譬喻,強調滅相之頓斷與超越語言之特質,並以聖人不取相之立場,統攝滅相之深義。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》對「滅相」的論述,重在破斥他部執有實在滅相之說,並以「相續」為立足點來安立有為三相(生、住、滅)。

首先,世親論師指出,其他部派主張:必須遇滅因緣,滅相方能滅所滅法。對此,本論提出反駁:若滅因緣本身即能壞滅所滅法,則何必再別執有「滅相」作為能滅之體?此譬喻猶如「服瀉藥時天來令利」——瀉藥自有瀉下之功,不必另假天神之力。同理,滅因緣既能壞滅諸法,便不須更立一實在之滅相,方能令法滅。

其次,本論以「心心所」刹那滅為例,進一步論證無需別求滅因緣。心與心所法刹那即滅,更不須待其餘的滅因緣方壞;若謂住用與滅用有先後之別,則一法於一時中應同時「住」與「滅」,如此則不應正理。由此可知,住、滅二用並無先後次第。

基於上述兩層破斥,本論提出自身立場:「故依相續說有為相,不違正理,善順契經」。也就是說,生、住、滅三相乃是依於有為法的相續假施設而立,並非別有實體之滅相能獨立壞滅所滅法。此一安立被本論判定為邏輯上不悖於理,亦與契經所說相吻合。

值得注意的是,在論述滅相之後,本論緊接著以「若生在未來,生所生法」提出另一問題:未來一切法何不俱生?此問題雖已逸出滅相之直接論述範圍,卻顯示出有為三相在本論體系中是環環相扣——若未來之生無先後差別,則相續中的生、住、滅諸相亦難以成立。

總結而言,《阿毘達磨俱舍論》對滅相的論述具有以下特點:其一,否認滅相為離於滅因緣之外、別有實在之能滅體;其二,以「心心所刹那滅」證成住、滅二用無先後;其三,主張有為三相乃依「相續」施設,故得「善順契經」之評價。本論所使用的核心術語包括「滅相」「滅因緣」「所滅法」「刹那滅」「有為相」「相續」「契經」「心心所」「有為法」等,皆為毘曇部共用的術語體系,其中「有為相」「相續」「刹那」「心心所」尤為毘曇部論書之慣用詞彙。

中論T1564 · 中觀部

《中論》透過多重推求論證「滅相」不可得,其論述核心在於指出生、住、滅三相彼此相待相違,單獨成立的滅相終不可得,所用關鍵術語為「滅相」、「生相」、「住相」,並在究竟處歸於「寂滅相」。

首先,《中論》從滅相與生相的矛盾論證滅相不可得。法若有滅相,則不應生,因為生相與滅相互相違背,二者不能同時成立(「二相相違法,一時則不然」)。進一步推求:「一切有為法念念滅故,無不滅法」,既然沒有決定不滅之法,則所謂「不滅法」亦無實義()。

其次,《中論》論證滅相與住相亦互相排斥。若法有滅相,則此法不應有住相,因為一法同時具有住相與滅相不成立(「一法中有二相相違故」「一法中而有住滅相,是事不然」);反之,若法有住相則無滅相,若住法而復有滅,則一法兼具二相,違反道理()。由此推導:「離住相則無法,無法云何滅?」()

第三,《中論》對「滅」作自他二分的檢查。若法有滅相,是法自相滅還是他相滅?兩者皆不然。以乳為喻:乳時不滅,因乳相定住;非乳時亦不滅,因已非乳,無從說是乳之滅()。

第四,《中論》以偈頌收攝:「如一切諸法,生相不可得;以無生相故,即亦無滅相」;以及「法不自相滅,他相亦不滅;如自相不生,他相亦不生」()。破生即無生,無生則無滅,此為《中論》的一貫推求結構()。

第五,《中論》正面指出滅相於推求中不可得。諸法有時,求滅相不可得,因一法中不應亦有亦無,如光影不同處()。若法先無,亦無滅相可論,如第二頭、第三手本無所有,無故不可斷()。

第六,《中論》將「滅相」引向究竟意義,與「寂滅相」相連。諸法從本已來無生,畢竟是寂滅相,世人執著種種分別(有我無我、善不善、有為無為等別異),即不得此寂滅相()。「如來寂滅相,而種種分別故」亦為邪見所破()。此處「寂滅相」與前所破之「滅相」同源而出,指諸法究竟之寂止相狀。

第七,《中論》批判「先有後無」之執。若法定有則不應無,有無各執定相則墮常見;若先有而壞為無則為斷滅,「若有斷常見者,則無罪福等,破世間事,是故應捨」()。又如瓶喻:瓶定在瓶相時無失壞相,無瓶時亦無失壞相,故滅不可得;離滅亦無生,因生滅相因待故()。

綜上,《中論》論「滅相」的獨特側面在於:從生、住、滅三相的相違相待切入,自他、自共、亦有亦無等多門檢查;以偈頌收攝於「無生故無滅」之原則;最終推向諸法畢竟寂滅相,以對治種種執有執無之戲論。全經以「滅相」標籤兼表所破之相,以「寂滅相」標示諸法本寂之正義,二者貫通為對生滅實有之全面破斥。
