What This Concept Is Actually Saying
成壞 is two Sanskrit words stitched together: vivarta (unfolding/formation, here rendered 成) and saṃvarta (re-folding/dissolution, here rendered 壞). In the *Mūlamadhyamakakārikā* (《中論》, T1564), Nāgārjuna takes this pair — the most natural way human beings narrate change — and subjects it to a systematic dismantling. The result is not a denial that things change, but a demonstration that the categories we use to *think* about change ("becoming established," "falling apart") have no self-nature (svabhāva) when we look closely.
The classical text defines the two terms in one clean sentence: "成名眾緣合，壞名眾緣散" — *成 is the convergence of conditions; 壞 is the dispersal of conditions*. This already locates 成壞 inside the framework of dependent origination (緣起, pratītyasamutpāda). Formation is not a magical materialization; it is the coming-together of causes and conditions. Destruction is not a hostile force smiting a thing; it is those same conditions falling apart. This is the launching point from which the refutation begins.
Now comes the dismantling. The 中論 does not stop at one argument. It deploys multiple "gates" (門) — interlocking analyses that close off every way you might try to re-establish 成 or 壞 as a real, findable event.
1. The 離 (separation) and 共 (co-arising) gates. The core verse: "離成及共成，是中無有壞；離壞及共壞，是中亦無成" — *Apart from 成 and apart from 共-成, no 壞 is found; apart from 壞 and apart from 共-壞, no 成 is found*. The argument unfolds: "若離於成者，云何而有壞？如離生有死，是事則不然" — *If 壞 were separate from 成, how could 壞 exist? It cannot be that death exists apart from birth*. The "separate" (離) gate says: pull 成 away from 壞, and 壞 has nothing to dissolve. The "co-arising" (共) gate says: but 成 and 壞 are contradictory — "成壞相違，云何一時有？如人有髮無髮不得一時俱" — *成 and 壞 are mutually opposed; how could they exist at one time? Like a person having hair and not having hair cannot both hold at once*. So the text asks the killer question: "成壞共無成，離亦無有成，是二俱不可，云何當有成？" — *Both the co-arising and the separated versions fail; how then could there be 成 at all?*
2. The 盡 (cessation) and 不盡 (non-cessation) gates. Someone might object: fine, but surely we observe things passing away, so the "ceasing" side must be real. The text answers: "盡則無有成，不盡亦無成；盡則無有壞，不盡亦無壞" — *Whether one says the dharmas are ceasing or not-ceasing, no 成 and no 壞 can be established either way*. Then it unpacks both terms. 盡 (cessation) is defined as "諸法日夜中念念常滅盡，過去如水流不住，是則名盡" — *The dharmas, day and night, moment-by-moment, are constantly ceasing; the past flows like water without staying — this is called 盡*. 不盡 (non-cessation) is defined as "念念生滅常相續不斷故名不盡" — *Moment-by-moment arising and passing, continuously uninterrupted, is called 不盡*. And here the text slips in a famous image: 盡相 is likened to 野馬 — the shimmering heat-haze over a distant plain (陽焰), which looks like water running but never actually arrives anywhere. The cessation we think we are observing is no more graspable than that mirage.
3. The mutual-dependence gate (法與成壞互依). "若離於成壞，是亦無有法；若當離於法，亦無有成壞" — *If we remove 成壞, there are no dharmas to talk about; if we remove the dharmas, there is no 成壞 to attribute to them*. And: "若離法，誰成誰壞" — *Apart from dharmas, who would form what, who would destroy what?*. There is no 成 or 壞 floating free of the events themselves, and no events floating free of the categories. They arise together and cannot be pried apart.
4. The 空 (empty) and 不空 (non-empty) gates. "若法性空者，誰當有成壞？若性不空者，亦無有成壞" — *If the nature of dharmas is empty, who could form or destroy? If their nature is not empty, then they would be fixed, and 成壞 also could not apply*. If everything is already settled, nothing can form; if everything is empty, there is no agent doing the forming. Either way: no 成壞 as a real event.
5. The 一 (identity) and 異 (difference) gates. "成壞若一者，是事則不然；成壞若異者，是事亦不然" — *If 成 and 壞 were identical, this cannot be; if they were different, this also cannot be*. The two standard metaphysical traps — collapsing them into one or splitting them into two — both fail.
The chapter closes with the unmistakeable summary: "即為破因果，作作者作法，亦復壞一切，萬物之生滅" — *This is to refute cause-and-effect, the doer and the deed, the making and what is made, and all arising-and-passing of the myriad things*. 成壞 is not a side topic. When the 中論 goes after formation and dissolution, it is going after the whole edifice of how we imagine events, causes, and identities to be real, graspable, narratable things.
Where does this sit in the path of liberation (解脫道)? 成壞 belongs to the middle stretch of the Prajñāpāramitā / Madhyamaka analysis — after the basic principle of dependent origination has been affirmed, and after impermanence (無常) has been established as a feature of experience, but *before* one has fully seen that the categories themselves ("becoming," "passing away," "thing," "event") are imputed without underlying essence. Its job is to dissolve the *metaphysics of change* — the unspoken assumption that there is a definite "thing" undergoing definite "events" — so that change can be experienced as the unobstructed display (遊戲, lit. "play") of conditions that it actually is. When 成 and 壞 no longer grip you as solid events, causality, agency, and selfhood lose their grip too.
Life Walkthrough: 成壞 at the Dinner Table, in the Group Chat, in the Mirror
The 中論 uses clean, spare images. Let's take the same structure and walk it through scenes a contemporary reader actually lives in. The discipline here is to *map each scene onto the classical definitions exactly*, not to lapse into the loose idea that "everything changes."
Scene A — A relationship that begins and ends. Two people meet, the conditions converge: shared context, mutual attention, time, desire. By the classical definition, this is 眾緣合 — 成, the coming-together of conditions. We say "we became a couple." The 中論 already has a question for that sentence: *what exactly is the "we" that became, separate from the conditions?* 離門 — pull 成 away from 壞 — and there is no "becoming a couple" to speak of, because there is no subsequent trajectory. 共門 — try to hold "becoming" and "falling apart" at the same instant, like "having hair and not having hair" — and it collapses. The couple doesn't form and dissolve in the same moment; the category is built on the assumption that they are two separable, identifiable events. Then, conditions shift: jobs change, attention drifts, misunderstandings accumulate. 眾緣散 — 壞, the dispersal. We say "we fell apart." But note what the text actually does: it does not deny that the conditions shifted. It denies that "falling apart" is a real event with a real agent and a real thing that underwent it. "若離法，誰成誰壞" — *apart from the actual shifting dharmas (the missed calls, the cold silences, the new interests), who was doing the forming and who was doing the breaking?* The breakup is not a thing that happened to a relationship. It is the name we give to a pattern of conditions.
Scene B — A career arc, in the language of "build" and "burnout." A founder starts a company: capital, team, customers, momentum. We say, "I built this." The 中論 would gently ask: where is the "I" that built, separable from the 眾緣合? When the conditions scatter — funding dries, key people leave, the market shifts — we say, "it collapsed." Again: the collapse is the dispersal of conditions, not a destructive force that struck a previously solid object. The most common mis-mapping here is to treat 成 as the *real* achievement and 壞 as the *real* failure. Both are reifications. The 盡/不盡 gates are particularly relevant in this scene: the moment-to-moment conditions (盡 — "念念常滅盡，過去如水流不住") are already running from day one, but the narrative arc of "I built this, then I lost this" is what gives the illusion of two solid endpoints. The 野馬 (mirage) image of 盡相 — water that never actually arrives — captures the way "burnout" or "collapse" often turns out to be a shape we imposed on a flowing process that never had the boundary we thought it did.
Scene C — The self-image that "forms" and "dissolves." You start a fitness regimen. The body changes; we say "I got in shape." Then life gets busy, the conditions scatter; we say "I fell out of shape." This is 成壞 at the smallest scale. The temptation is to treat "the body that got in shape" as a real object that later underwent a real event ("falling out"). The 中論: if you separate the "in-shape" state from the "out-of-shape" state (異), you cannot find the line where one ended and the other began, because moment-by-moment (念念) the body has been continuously arising and passing. If you collapse them into one (一), you cannot account for the felt difference. Both the "I who built this body" and "the body that was destroyed" are constructs placed on top of an unmarked flow.
Where the mis-mapping usually happens. In every one of these scenes, the classical error is the same: we treat 成 as the *positive* pole (a real achievement, a real becoming) and 壞 as the *negative* pole (a real loss, a real destruction), and we orient our whole emotional life around which pole we are on. The 中論's contribution is not to say "neither ever happened" (that would be the nihilist trap). It is to say: the two categories are not findable as solid, independent events — they are mutually dependent, neither separable nor coexistent, neither identical with nor different from the conditions that constitute them. This changes what is available to you in each scene.
Why Contemporary People Need This Analysis
Contemporary culture is saturated with narratives of 成 and 壞. Productivity culture tells us to "build" — build a company, build a brand, build a body, build a relationship, build a self. Self-help literature is essentially a manual for treating 成 (formation, achievement, becoming) as the only thing that counts. When the conditions don't cooperate — and they always eventually don't — the same culture flips into its shadow: stories of "burnout," "collapse," "ruin," "falling apart." Social media amplifies both poles by giving them the visual weight of "before" and "after" images. The whole emotional economy of contemporary life runs on the assumption that 成 and 壞 are *real events* that happen *to real things*.
The 中論's analysis of 成壞 is, in this context, almost shockingly practical. It does not say "don't try to build things" or "everything will end so don't bother." It says something more precise and more liberating: the "thing that was built" and the "thing that collapsed" are themselves conceptual overlays on a flow of conditions that has no such internal boundaries. When this is genuinely seen — not just intellectually affirmed — the grip of both narratives loosens. You can still build; you just don't load the build with the metaphysical drama of "this is a real thing I am bringing into existence." You can still grieve loss; you just don't load the loss with the metaphysical drama of "a real thing has been destroyed."
There is also a contemporary cognitive-science resonance worth naming carefully. Research on event perception suggests that the brain does not receive "events" as raw data; it *constructs* them by segmenting continuous experience and assigning boundaries, agents, and causal structures. The brain builds "the meeting," "the breakup," "the project" — and these constructions are useful for navigation but are not features of the world itself. This is loosely consonant with the 中論's claim that 成壞 are *constructed categories*, not found events. But the consonance is loose: neuroscience describes the *mechanics* of segmentation; Madhyamaka is making an *ontological* claim about the lack of underlying essence in those constructions. The two should not be conflated, and neuroscience certainly does not "prove" 中觀. The analogy helps; it does not substitute.
There is a parallel in computational thinking. A software project's "release" and its "deprecation" look like 成 and 壞 — discrete events with dates and tickets. But the code is a continuously running process; the events are imposed milestones. Treating the project as having a "life" with a real birth and a real death is convenient for project management and misleading for understanding. Same logic, much less freight.
Common Misreadings and Clarifications
Misreading 1: "This is just impermanence (無常) restated." Not quite. 無常 (anitya) says dharmas do not endure; 成壞 says the *categories* of "formation" and "destruction" cannot be established as real events. You could affirm impermanence forever and still be gripped by the sense of a real "becoming" and a real "ending." The 中論 goes one step further: it targets the *metaphysics of change*, not just the fact of it.
Misreading 2: "This is nihilism — nothing ever forms or destroys." The text explicitly refuses this. 成 is defined as 眾緣合, 壞 as 眾緣散 — *conditions do converge, conditions do disperse*. What is denied is the existence of a real, independently-existing event called 成 or 壞 over and above the conditions. The mirror image of the nihilist misreading is also wrong: this is not "everything stays the same." Things change continuously (念念生滅). The denial is of the *reification* of that change into discrete formations and destructions.
Misreading 3: "成 and 壞 are two things, and 中論 just says they're connected." This collapses the analysis. The 中論 does not just say 成 and 壞 are "connected." It runs them through six gates (離/共, 盡/不盡, 法/成壞, 空/不空, 一/異) to show that *no* metaphysical relation between them holds. The pair cannot be separated, cannot coexist, cannot be identified with the dharmas, cannot be abstracted from them, cannot be the same as each other, cannot be different from each other. Each "cannot" is a specific philosophical move, not a vague gesture toward interconnection.
Misreading 4: "If there's no 成 or 壞, then effort and consequence don't matter." The closing verse of the chapter is the antidote to this: "即為破因果，作作者作法，亦復壞一切，萬物之生滅" — *This refutes cause-and-effect, the doer and the deed, the making and what is made*. The point is *not* that cause and effect don't operate. The point is that when you fully examine what "cause," "effect," "doer," and "deed" are, you cannot find them as self-existing entities either. Effort still functions within dependent origination; what is dismantled is the *metaphysical drama* of a sovereign self producing real events that leave real marks on real things. This is what creates room for compassion without burnout, and action without reification.
Misreading 5: "The 野馬 (mirage) metaphor means change is an illusion." The metaphor is doing specific work in a specific gate (the 盡/cessation gate), not a global claim. 盡相 — the "cessation" we think we observe — is likened to the mirage: it has the *appearance* of something happening (water running) but no findable substance. This applies to the *cessation pole of the pair*, not to all of experience. The full verse pairs 盡 with 不盡: the flow is also not graspable as a steady substance. The mirage image is one precise tool in one precise argument, not a license to declare all change unreal.
The deepest thing the 成壞 chapter is doing is removing the ground under a particular habit of mind: the habit of looking at a stream of conditions and seeing, behind it, "a thing that formed" and "a thing that broke." When that habit is loosened — not destroyed, because there is nothing to destroy — what remains is not emptiness as void, but the unobstructed operation of conditions, no longer shadowed by a story of "becoming" and "ruin" that never quite belonged to them.
