Note on translation: 不定業 literally means "not-fixed karma" or "undetermined karma." In classical Abhidharma (the Buddhist analytical tradition focused on enumerating dharmas), it refers to karmic actions whose fruiting — its timing, location, and severity — is not yet locked in. In this piece I will use "indeterminate karma" as the working English term, but please keep in mind that what is being called "indeterminate" is the *result*, not the action itself.
一、这个概念在说什么
不定業 is one of three classical categories of karma (業/karma), and it sits inside a debate that runs through the entire history of Buddhist thought about moral cause and effect. To understand it, you need to see all three categories at once, because they are a tightly interlocking system — and then you need to see what happens when the *Madhyamaka Śāstra* (《中論》, T1564, Nāgārjuna with Piṅgala's commentary, Kumārajīva's translation) takes a sledgehammer to the whole taxonomy.
1. The three karma categories (Abhidharma framework)
In the Abhidharma traditions — the schools that carefully classified all mental and physical phenomena — karma was divided by the determinacy of its result:
- 定業 (definite karma): an action whose ripening time, place, and severity are essentially fixed. Think of the most extreme cases — in traditional lists, killing one's own parent, killing an arhat, maliciously wounding a Buddha, and so on. These, the tradition held, produce severe and predictable results in this life or the next. - 不定業 (indeterminate karma): an action whose ripening time, place, and severity are *not* fixed. These are the vast majority of ordinary actions — the daily small moral and immoral acts that could ripen soon, late, lightly, or heavily depending on conditions. - 定不定業 (mixed definite-indefinite karma): an action whose ripening is determined in *some* respects but not in others — for instance, the timing might be fixed but the severity is not, or vice versa.
This three-fold schema was the Abhidharma attempt to do justice to ordinary moral experience: some karmas seem to land hard and fast, others seem to drift around for lifetimes, and most are somewhere in between. The categories were not casual. They were tied to elaborate sub-classifications: whether the action bears fruit in the *current life* (現世受果報), after death but in the next life (報已猶在), or only after some karmic "debt" has been discharged (度果已滅). They were also classified by whether the action is *worldly* (有漏, "tainted," still binding one to saṃsāra) or *transcendent* (無漏, "untainted," the activity of arhats and bodhisattvas).
Underneath all of this lay a working assumption that Buddhist scholasticism rarely stated bluntly: karma has a kind of existence, a way of being stored and called upon for ripening. To make the categories meaningful, the system needed a mechanism by which an action performed now could remain "on the books" until it bore fruit — perhaps decades later, perhaps in a future life.
2. The mechanism the Abhidharma school proposed: 不失法 (the non-loss dharma)
This is where the *Vaibhāṣika* / *Abhidharma* theory of 不失法 comes in. The opponents quoted in the 《中論》 — using 毘曇 (likely a reference to Vaibhāṣika or Śrāvakābhidharma materials) — proposed that there is a kind of neutral, morally indeterminate factor (無記/avyākṛta) whose job is to preserve karma until the moment of fruition. They illustrated it with a famous analogy:
「不失法如券，業如負財物」— "The non-loss dharma is like an IOU; karma is like the borrowed goods."
In other words, when you act, an "IOU" is written. The IOU sits in storage (in consciousness, in some subtle mental continuum) until the right conditions arise, and *then* the karma "ripens" and produces its effect.
This 不失法 was carefully placed in the system: - It is morally *neutral* (無記), neither good nor bad. - It belongs to the *meditative* sphere rather than the *insight* sphere — meaning it is "cut" by deep meditative cultivation (思惟所斷) but not by initial penetration of the four truths (見諦所不斷). - It can be tied to the desire realm (欲界), the form realm (色界), the formless realm (無色界), or be unbound (不繫). - It operates for āryas (nobles) and ordinary beings alike.
This was, in its own way, an elegant piece of Buddhist accounting. It explained *why* karma could wait, and *what* waited with it.
3. What the 《中論》 does with all this — and why 不定業 is not just "the middle category"
Here is the part that surprises contemporary readers most. The 《中論》 does not define 不定業 positively. It does not say "indeterminate karma is the kind of karma where…" Instead, it puts all three categories on the operating table and performs Madhyamaka (中觀) surgery on the underlying assumption they all share: that karma has fixed nature (定性), that it can be classified as *definite* or *indefinite* in any absolute sense.
The argument unfolds in four moves.
Move 1: Pairing 定 with 有 and 不定 with 無. The text establishes an equation: *definite* is paired with *being/existence* (有); *indefinite* is paired with *non-being/non-existence* (無). This is a conceptual move — if a thing is "definitely so," it has a fixed nature, which the Abhidharma system elsewhere takes as a marker of real existence; if it is "indefinitely so," it doesn't have that fixed nature and so is closer to non-being.
Move 2: Exposing the contradiction in 定不定業. Given this pairing, the category "定不定業" tries to combine being and non-being in the same action:
「有是決定、無是不決定，一人一事云何有有無？」— "Being is determined; non-being is undetermined. How can one person, one act, possess being *and* non-being?"
This is the core refutation. If 定 requires 有 and 不定 requires 無, then 定不定業 is internally contradictory from the start — it tries to be and not-be at the same time.
Move 3: The agent collapses too. If no act can be both 定 and 不定, then no agent (作者) can be either — or both — when performing the act:
「作者不作定，亦不作不定，及定不定業，其過如先說」— "The agent does not produce definite karma, does not produce indefinite karma, does not produce definite-indefinite karma; the error is as before."
「作者定不定、亦定亦不定，不能作於業，其過如先說」— "The agent, whether determined, undetermined, or both, cannot produce karma; the error is as before."
The 《中論》 explicitly flags this as 一時總破 — a "total refutation in one sweep." Once 定不定業 is exposed as incoherent, 定業 and 不定業 lose their footing too, because they were defined by contrast with it. The whole taxonomy collapses together.
Move 4: The 不失法 theory is also caught. When the opponent appeals to the "IOU" mechanism, the 《中論》 pushes the same analysis onto it. If the 不失法 "preserves" karma from the moment of action until the moment of ripening, then either:
- The karma *persists* unchanged until fruition — but then it is *permanent* (常), which contradicts the Buddha's teaching of impermanence. - The karma *is destroyed* before fruition — but then there is no karma left to bear fruit, so how does the result arise?
The text states this dilemma in a famous verse:
「業住至受報，是業即為常；若滅即無業，云何生果報？」— "If karma abides until its result, that karma is permanent; if it is destroyed, there is no karma — how then does it produce its fruit?"
The 不失法 theory falls into either *eternalism* (常, asserting a permanent substrate) or *nihilism* (斷, denying any continuity). Neither horn is acceptable.
The conclusion: 諸業本不生. The 《中論》 arrives at a startling final position:
「諸業本不生，以無定性故；諸業亦不滅，以其不生故。若業有性者，是則名為常，不作亦名業，常則不可作……若諸世間業，從於煩惱生，是煩惱非實，業當何有實？」— "All karma is originally unarisen, because it lacks fixed nature; all karma is also un-extinguished, because it is unarisen. If karma had fixed nature, it would be called permanent; even without being made, it would be called karma; that which is permanent cannot be made… If worldly karma arises from afflictions, and those afflictions are not real, how could karma be real?"
Notice carefully what this *is* and *is not* saying. It is not saying "nothing happens when you act," or "consequences don't exist," or "you can do anything and it doesn't matter." It is saying that the substance-view of karma — the idea that karma is a "thing" with fixed nature that can be stored, transferred, classified, and predicted — does not hold up. Karma functions, but it functions *without inherent nature* (無自性), relationally, conditionally, like everything else in dependent origination (緣起).
This is the place of 不定業 in the entire map of liberation: it is the *site of the debate itself*. The category was set up to make sense of why some actions seem to ripen fast and others slowly. The 《中論》 grants the *experience* but refuses the *category*, because the category smuggles in the very substance-view it must give up to be coherent.
二、生活里的走查
Let me walk this concept through several scenes from a contemporary week. I'll keep the Abhidharma categories on the table first — what would each say about the karma at issue — and then bring the 《中論》's critique to bear, because both belong to this concept.
Scene 1: The commute that almost happened
You are driving to work, late, frustrated, and someone cuts you off. Your hand tightens on the wheel. Your mouth opens. You almost scream something at them — and then you swallow it. You don't act on the impulse. You feel the anger rise and pass.
- The Abhidharma reading: the *impulse itself* — the mental moment of intending harm (意業) — is karma, even without physical action. Whether its fruit is 定, 不定, or 定不定 is hard to say. A passing irritation that dies in the next minute may well be 不定業: present, real, but its exact ripening deferred. Or it could be 定不定 — it has determined *something* (say, the immediate contraction in your chest) but the long-term effect is open. - The 《中論》's challenge: *who* is "you" in this scene? Was there a fixed "you" who made the choice to swallow the anger? Or did a complex of conditions — sleep, traffic, the other driver, your morning, your breath — produce a relational event that we then label "decision"? The label "不定業" presupposes that there is a fixed subject producing a fixed object of karma. There isn't, on closer look.
Where people commonly mis-map this scene: they assume that because they *didn't* act out the impulse, no karma was made. The Abhidharma would say: the mental intention itself was karma, and its lightness or heaviness depends on the depth of the underlying tendency. The 《中論》 would say: don't try to escape into the comfort of "no karma either way" — but also don't try to make the karma into a quantifiable ledger entry.
Scene 2: The donation that isn't quite yours
A friend asks you to contribute to a charity. You want to say no — you don't love this particular cause — but you say yes because of the relationship. The money goes out. There is a faint residue of resentment in you for weeks.
- Abhidharma reading: the *act* of giving (布施) is karmically significant. Whether its result is determined depends partly on the *mental quality* behind it. A gift given with resentment might still bear fruit, but it might be *less* determined in producing the usual "merit" — or its timing might be indeterminate. This is a place where the 不定/定不定 boundary might matter practically. - 《中論》's challenge: the moment you start calculating "how much merit is this, and how does it compare to giving cheerfully?" you have entered the territory of substance-thinking. Karma is not a commodity whose quantity can be measured by the purity of your motive.
Common mis-mapping: equating "indeterminate" with "weak." *Severity* and *determinacy* are different axes. An action can be *morally light* but *completely determined* in its result; another can be *morally heavy* but *completely indeterminate* in its result. The category 不定業 tells you nothing about whether the result will be small.
Scene 3: The lie that wasn't a lie
In a meeting at work, you fudge a number to make a deadline. Not a big deal in the moment. Two years later, you notice that you no longer trust your own reports. Something has eroded in your relationship with your own honesty.
- Abhidharma reading: the original lie was, most likely, 不定業 — its severity and timing were not predetermined. The erosion that followed is its ripening, but in a form no ledger could have predicted: it was not "punishment," it was the slow change of your own self-image. - 《中論》's challenge: see how tempting it is to say "the lie *caused* the erosion, as a substance causes its effect." The actual process is far more relational: the lie, the people you lied to, the pattern of your work, your relationship to your own self-respect — all of these co-arising over time produced the erosion. There is no compact "lie-IUO" sitting in storage that got cashed in.
Where people mis-map this: the move from "karma is indeterminate" to "karma doesn't really matter, so I'll keep doing it." But indeterminacy is not permission. It is a description of how moral causality actually unfolds — relationally, often slowly, often invisibly, and not in the clean ledger form we might hope for.
Scene 4: The parent who snaps
It is 10 p.m. You have worked overtime. The child won't sleep. You snap — say something you'll regret. Then you sit on the stairs and feel awful about it.
- Abhidharma reading: the act of speech (語業) and the underlying anger (瞋) are karma. The severity might be 定 or 不定 depending on how habitual the pattern is. If this is the first time, indeterminate. If it is the thousandth, much more determined — the pattern itself becomes a "fixed" karmic force. - 《中論》's challenge: the desperate comfort of either "this didn't matter" (nihilism) or "this will be repaid in equal measure" (substance-eternalism) — both miss the point. What matters is the *present relational situation*: the child who heard you, the pattern being reinforced in both of you, the self-image being constructed. Fixating on karmic accounting in either direction distracts from the work of repair.
Common mis-mapping: assuming that 不定業 is a "karmic insurance policy" — that indeterminate things might just not happen. They will almost certainly happen; we just don't know when or how.
Scene 5: The not-yet-action
You are in a position of moderate power. You could either speak up about a small injustice at work, or stay quiet. You stay quiet — not out of fear, just out of not wanting to make a thing of it. The question sits in you.
- Abhidharma reading: your *omission* — your choice not to act — is itself a moral phenomenon. Many schools would say that failure to act when action was possible is a form of karma, often indeterminate in result. - 《中論》's challenge: the question "did I do the right thing?" presupposes a self who is the owner of "the right thing." The relational view: what mattered was not the "decision" but the way the situation actually moved, including you in it. Did anything change in the situation because you stayed quiet? Did anything change in *you*? Those are the karmic facts, and they are not entries in a ledger.
Where people mis-map this: assuming that 不定業 covers only *small* actions and that *big* moral choices have *definite* karma. In fact, the reverse is often closer to truth: the really big moral choices are usually the ones whose long-term consequences are *most* indeterminate, because they participate in the most complex causal webs.
Scene 6: The brain-science overlay (with caution)
Modern neuroscience is fond of noting that most of what we "decide" is decided before conscious awareness — Daniel Wegner's "conscious will" research, Benjamin Libet's experiments, Antonio Damasio's somatic marker hypothesis, and so on. There is genuine research here. It is also genuinely contested (see the critiques by Soon et al. in the replication literature, and the broader methodological debate about what "unconscious decision-making" actually shows).
It is tempting to map this onto 不定業: "see, the results of our actions are determined by unconscious processes, so karma is really not 'ours' at all." The 《中論》 would warn against this mapping. Two reasons. First, it merely substitutes one substance-view for another — now the "unconscious" is the new permanent substrate, the new 不失法. Second, the Madhyamaka point is not that there is *no* agent, no will, no cause and effect — it is that none of these have *fixed nature*. The neuroscience observation, if accurate, is interesting and consistent with the relational view: karma arises from conditions, not from a fixed self. But it does not "prove" the Buddhist view, and certainly not the Abhidharma taxonomy, and it certainly does not refute it. (For an accessible discussion of how Buddhist thinkers have approached the mind-body and agency problem, see essays in the *Stanford Encyclopedia of Philosophy* on Buddhist philosophy; for the specific question of karma and determinism, see the entries on karma and dependent origination.)
三、当代人为什么需要它
1. Because we are drowning in karmic spreadsheets
Modern people — even non-religious modern people — quietly run their lives on a kind of karmic accounting. "If I work hard now, it will pay off." "If I was rude to that person, it will come back." "I am reaping what I sowed." This is comforting and it is also deeply distorting. It encourages a kind of moral bookkeeping that the 《中論》 refuses to validate.
不定業 is, in the Abhidharma system, *the most common category*. Almost everything we do is indeterminate in result. This means that the bulk of our moral life is *not* legible to a ledger. We cannot fully compute its consequences. That is not a problem to solve; it is a description of reality.
When we absorb this, we stop demanding of life that it be a transparent reward system. We also stop demanding of ourselves that we be perfectly legible moral calculators. We are not. We act, and the consequences ripple out in ways we cannot fully trace.
2. Because it liberates us from two false comforts
The 《中論》's critique of 不定業 liberates us from two opposite errors:
- Fatalism / eternalism (常邊): "My karma is fixed, my future is sealed, nothing I do matters." This treats karma as a permanent substance that determines the future. The 《中論》 refuses this: if karma were permanent, it could not even be produced. - Nihilism / quietism (斷邊): "Karma is just an idea, so ethics is optional." This denies any continuity between action and result. The 《中論》 refuses this: if karma were annihilated the moment it was produced, there would be nothing to produce any result.
Indeterminate karma sits *between* these two mistakes, and the 《中論》's radical move is to show that the very categories (定 / 不定 / 定不定) that seem to mediate between them are themselves built on the same false premise of 實有 (real existence).
For contemporary practice, this means: *act ethically without being able to compute the result*. This is a very different posture from "do good because you'll be rewarded" or "do good because there's no cost to doing good." It is closer to: *act ethically because the acting is what there is, and the consequences are not yours to predict*.
3. Because the 不失法 critique matters now
The Vaibhāṣika's "IOU" mechanism for karma is, in contemporary dress, the assumption that moral consequences are *stored* somewhere — in the universe, in your soul, in your karma bank, in your aura. Modern people who don't use the word karma still use this assumption. "What goes around comes around" is the folk version. The 《中論》's question — *if the karma persists unchanged until fruition, it is permanent; if it doesn't persist, how can it ripen?* — is a serious challenge to this folk metaphysics. You can't have your karma and store it too.
The contemporary relevance: this is the question to ask whenever someone offers you a tidy account of how moral consequences "work." What is the substrate? How long does it last? What happens to it before it ripens? If the substrate is permanent, you have invented an eternal soul. If it is destroyed, you have no continuity between action and consequence. The Madhyamaka response is: *neither — moral consequences are relational events, not stored substances*.
4. Because it reframes anxiety about past actions
Many people carry guilt about actions whose consequences they cannot see. The Abhidharma framework offers one kind of relief: the consequences are indeterminate, so perhaps they will be light. The 《中論》 offers a deeper relief: the entire "consequence" model needs to be rethought as relational, not ledger-like. What matters is not the hidden fruit, but the *present quality of the relational situation*, which is always available to be changed.
The 《中論》 does not invite you to stop caring about the past. It invites you to stop *fixating* on a particular metaphysical picture of how the past determines the future. Repair is possible; the question of whether the past has "stored karma" against you is, on the Madhyamaka view, the wrong question.
四、常见误读与澄清
Misreading 1: "不定業 means light karma"
This is the most common confusion. *Determinacy* (定 vs. 不定) and *severity* (輕重) are different dimensions in the classical schema. An action can be completely determined in result and yet extremely light (e.g., a habitual courtesy that yields small predictable benefits). Another action can be completely indeterminate in result and yet extremely heavy (e.g., a casual lie that destroys a relationship over years). 不定業 refers to *how fixed the result is*, not to *how big it is*.
Misreading 2: "不定業 means the karmic result might not happen"
This is the "karmic insurance" misreading. In the Abhidharma framework, 不定業 does *not* mean "this action might produce no result at all." It means "this action's result has not yet been fixed in time, place, and severity." A result will still ripen; we just don't know when, where, or how strongly. The 《中論》 would go further: the entire idea of "result" as a determinate thing-in-waiting is the substance-view it is critiquing. But even within the framework being critiqued, "indeterminate" is not "optional."
Misreading 3: "The 《中論》 says karma doesn't exist, so ethics is meaningless"
This is the most serious misreading, and it is what the text carefully guards against. The 《中論》's conclusion "諸業本不生" (all karma is originally unarisen) is not a denial that karma functions or that ethics matter. It is a refusal of the *substance-view* of karma. The text's own closing verse makes this clear: "若諸世間業，從於煩惱生，是煩惱非實，業當何有實？" — if karma arises from afflictions, and those afflictions have no fixed nature, how could karma have fixed nature? This is a statement about the *nature* of karma, not about its *existence-as-functioning*. Madhyamaka philosophy distinguishes carefully between *inherent existence* (自性) and *conventional functioning* (世俗). To collapse this distinction is to commit the very error the 《中論》 is critiquing — just on the nihilistic side.
Misreading 4: "If karma is indeterminate, I can never know if I'm doing the right thing"
This is the existential-anxiety misreading. The 《中論》's position is not "we can never know" — it is "we cannot know *because the question presupposes a metaphysics that does not hold*." The question "is this action definitely going to produce a definitely-knowable result?" assumes the substance-view. The better question is: "is this action, in this relational situation, contributing to suffering or to its ending?" That question is answerable. It is answerable in the present, not in some future ledger.
Misreading 5: "The 不失法 theory is just a quaint medieval belief"
It is easy to dismiss the 不失法 as an outdated philosophical apparatus. But the underlying claim — that there is some mechanism by which actions persist until they produce results — is still alive. It appears as: the doctrine of stored merit, the belief in cosmic balancing, the idea that "the universe" keeps accounts, the assumption that morality is a closed system. The 《中論》's critique of 不失法 applies to all of these. *Any* account of how karma "gets stored" runs into the same dilemma: either it persists (and is permanent) or it doesn't (and cannot produce results). The lesson is that moral consequences do not require a storage mechanism. They unfold relationally, moment by moment, in conditions that include the action but are not exhausted by it.
Misreading 6: "This is just about whether karma 'exists' or not — but I don't believe in karma anyway, so why does this matter?"
Even setting aside the metaphysical question, the *category* of 不定業 and its critique matter for anyone who thinks about ethics, agency, and consequence. We all operate with implicit theories about whether actions have fixed consequences or open ones, whether moral outcomes are predictable or relational, whether "the universe" keeps score. The 《中論》's argument is not just a Buddhist technicality; it is a sustained critique of moral bookkeeping in any form. To read it is to notice the bookkeeping one does oneself.
A closing note
The category 不定業 was invented to solve a real problem: most of our actions do not produce predictable, proportionate, immediate results. We needed a place to put them in our karmic taxonomy, and "indeterminate" was that place. The 《中論》 looks at this solution and says: *you have solved the problem by inventing a substance, and the substance-view is what is creating the problem in the first place*. The way out is not a better taxonomy. The way out is to notice that the whole project of taxonomic bookkeeping — of trying to file every action under 定, 不定, or 定不定, with an IOU stored against it — is itself a kind of grasping.
What is left, when the grasping is exposed? The actions themselves. The relationships they enter. The present quality of attention and care we bring. The possibility of repair, always available, never guaranteed by any prior ledger. This is not a comfortable picture. It is also the one the 《中論》 insists is closer to the truth of how things actually unfold.
