There's something slightly unusual about this concept right at the start: it isn't really a *teaching*. It's a view that gets named in order to be set aside. The 《大般涅槃经》 (Mahāparinirvāṇa Sūtra), in the Northern Liang translation by Dharmakṣema (曇無讖) that we have as T0374, brings up "三世有法" specifically to declare that it has "无有是处" — no tenable ground, no place where it can stand. The sūtra isn't offering "three-time existence of dharmas" as something to believe in. It's pointing to a hidden assumption many of us carry and gently dismantling it.
That's where we'll begin, and that's where we'll end. Let's walk through it.
这个概念在说什么
The relevant verse, repeated in slightly varying forms across four places in the sūtra, runs:
本有今无，本无今有。三世有法，无有是处。
A working translation:
What was existent is now non-existent; what was non-existent is now existent. That dharmas exist across past, present, and future — there is no ground for this.
Four terms carry the whole argument. Let's take them one at a time.
本 (běn) — "the prior," the state before. Not "the past" as an abstract time, but the situation as it was previously observed.
今 (jīn) — "the present," the state as it is observed now.
有 (yǒu) — existent, present, identifiable, available.
无 (wú) — non-existent, absent, no longer or not yet identifiable.
The verse pairs these in two complementary transitions:
- 本有今无 (běn yǒu jīn wú) — formerly existent, now non-existent. The direction of cessation: something that was here, now isn't. - 本无今有 (běn wú jīn yǒu) — formerly non-existent, now existent. The direction of arising: something that wasn't here, now is.
Together these cover the basic texture of conditioned things: they appear, and they pass. The sūtra doesn't need to prove this — it points to it as something observable. Anyone watching their own life for a few minutes can find both directions.
Now the punchline:
三世有法 (sānshì yǒu fǎ) — "dharma(s) existing across the three times." The "three times" (三世) are 过去 (past), 现在 (present), 未来 (future). The proposition being refuted is that a given dharma — a phenomenon, a being, a fact — has existence that runs *continuously* through all three: it *was*, it *is*, it *will be*, as one unbroken existent.
无有是处 (wú yǒu shì chù) — "there is no place where this stands." 是处 literally means "a place where this could be established," i.e., a valid reason or tenable ground. The phrase says: this proposition has no tenable basis.
So the argument has a tight two-step structure: (1) observable change between 本 and 今 in both directions; (2) therefore, the claim that a dharma persists as one continuous existent across all three times has no ground.
A note on what is NOT in the verse. The provided canonical excerpt is minimalist. The sūtra, in the material we have, doesn't separately analyze the "ontology" of past dhārmas, present dhārmas, and future dhārmas; it doesn't construct a three-time taxonomy; it doesn't list specific types of dhārmic examples. The argument is highly compressed: 生灭变异 → 三世有法 无是处. A reader who tries to graft elaborate doctrinal schemes onto the verse is doing more work than the text itself does. This is worth honoring: the sūtra's point lands precisely because it doesn't over-build. (The four textual instances vary only in word-order — in one of them the clauses are flipped to 本无今有, 本有今无 — and the doctrinal content is identical.)
A brief doctrinal context, honestly flagged. In broader Buddhist history, the position that 三世有法 critiques has a name: the 一切有部 (Sarvāstivāda, "the school that maintains everything exists") — a major early Buddhist school whose very name encodes the thesis that dhārmic factors have real existence across all three times. The 涅槃经's verse here is one strand of the long canonical and philosophical conversation about whether dhārmic factors truly "exist" before they manifest, while they manifest, and after they cease. I'll flag this as historical context, not as something the provided excerpt itself spells out. The text we have simply says: this view has no ground.
生活里的走查
The cleanest way to feel this verse is to walk through it. The mapping isn't metaphor — each classical component finds a very literal home in ordinary contemporary experience.
本有今无: things that used to be, and now aren't
Pick up any long-standing situation in your life. Has it changed?
A job that ended. You worked somewhere for years. You had colleagues you saw daily, a routine, a way of being-in-the-world that "you" plus "that workplace" co-created. Then a layoff, a resignation, a closure. The role is gone. The colleagues are out of your daily reach. The routine doesn't exist. The "you-in-that-job" doesn't exist now in the way it did. 本有今无, plainly: it was, and now it isn't.
A relationship that has run its course. A romantic partnership that dissolved two years ago. You still have the memories, the photos, the in-jokes. But the "we" — the actual shared life, the daily intertwining — doesn't exist now. It's not "elsewhere"; it's nowhere. The contact may still be in your phone, but the relationship as it was doesn't exist.
A friendship that faded. You and a college friend were once close. You can still reach them. But the texture of conversation you had, the easy intimacy, the shared references — those are gone. The friendship-as-it-was doesn't exist now, even though both of you do.
A skill you used to have. A language you once spoke fluently, a sport you once played, a piece of music you once performed. You might still know a little. But the skill as a living, available capacity — it doesn't exist now.
Yesterday itself. Even the experience of yesterday doesn't exist now. You have traces: a memory, a journal entry, a photo. But the experience itself was over when 今 arrived. 本有今无 is built into the very movement of time.
*What this maps to, precisely.* 本 refers to the prior state of the *same* phenomenon (your old job, the relationship, the skill). 今 refers to the present state of that same phenomenon. The verse isn't about "the past" vanishing in some abstract sense — it's about the same thing undergoing transition from 有 to 无.
本无今有: things that weren't, and now are
Now look for the reverse direction. The same honesty, the same observations.
A child who arrived. Before your child was born, your life was one configuration; after, it's a very different one. The "person who is a parent to this child" didn't exist before. Now it does.
A new capacity. You couldn't swim. Then you could. You couldn't code. Then you could. You couldn't read a particular kind of theory. Then you could. The capacity wasn't in your life; now it is.
A chance encounter becoming central. Someone you met by accident is now one of the most important people in your life. They didn't exist in your world before; now they do. The "you-who-is-close-to-this-person" didn't exist; now it does.
A recovery. A capacity you thought you'd lost returns — movement after an injury, focus after a difficult period. The "no longer able to" becomes "now able to."
A new seeing. A pattern in your behavior you didn't notice for years; then you do. The seeing didn't exist; now it does. You can't unsee it.
*What this maps to, precisely.* Same shape: it's the *same* phenomenon that undergoes the transition. The child, the capacity, the person, the seeing. The verse is registering that 本 was without this, and 今 is with it.
三世有法 — where the assumption sneaks in
The proposition 三世有法 asserts that a given dharma exists across past, present, AND future as *one continuous existent*. Here's where it gets interesting, because this view is so common we don't notice it. It's the silent background assumption of a lot of how we live.
"I will always have this." A job. A friendship. A city. A phase of life. We carry it forward as a kind of mental furniture: I've always had it, I have it now, I'll have it tomorrow. Past-present-future are imagined as one continuous existent. 本有今无 is not built into the projection. It's as if the present will simply keep being present.
"We've always been like this." A relationship, a workplace, a community — projecting a current pattern backward to imagine it has always existed, then forward to assume it always will. The actual texture, looked at honestly, has ups and downs, gaps, real transitions. The 三世有法 frame smooths over the discontinuities.
"I've always been this kind of person." Looking at old photos, we often say this. But a sober look at "you" fifteen years ago usually reveals someone with different capacities, different concerns, different values, different ways of being. The continuous "me" that runs from past to present to future is partly a story we tell, not a phenomenon we observe.
"My data has always been there." Cloud storage, social media, the "permanent" photo archive — we build infrastructures that feel like three-time existence. The file from five years ago is "there." The platform feels permanent. The you-in-the-photo and the you-now feel like one continuous thread. But platforms die, accounts get deleted, files corrupt, servers fail. And even within a continuous archive, the actual experience captured in those files is not the experience of now.
Where this hurts most: grief. When someone dies, we often feel their absence as a violation of cosmic order. They should still be here. The past-they-existed and the present-they-should-still-exist and the future-we-would-have-shared feel, in the 三世有法 view, like one continuous "us" that has been wrongly cut. The pain of grief often comes precisely from bumping into 本有今无: the person WAS, and now ISN'T, and our ordinary categories don't have a place for that. The 涅槃经's teaching doesn't erase the pain. But it offers a frame in which 本有今无 is part of how things are, not a wrongness to be resolved.
The deepest and most silent form: "I" exists across three times. "I did X yesterday, I am doing Y today, I will do Z tomorrow." The "I" feels the same in all three clauses. This is probably the most entrenched 三世有法 assumption of all — that the subject, the "I," is a continuous existent running through past, present, and future. The 涅槃经's argument applies here too: what was "I" before isn't exactly "I" now, and what "I" am now won't exactly be "I" later. The assumption of a single "I" across three times is doing a lot of quiet work in how we live.
Where the mapping goes wrong
The most common errors that come up here:
- Treating 三世有法 as "all things are impermanent." These are related but distinct. The verse makes a *specific* refutation of a *specific* view using observable change as evidence. The broader doctrine of impermanence is a more general principle. Conflating them flattens the precision of the verse. - Thinking the sūtra says "nothing exists." It doesn't. The negation is of continuous three-time existence, not of existence altogether. Within any given moment, things do exist. - Reading 本 as "the past" as an abstract time. It doesn't. It means the prior state of the *same* phenomenon. The point is change of one thing across time, not the passage of clock-time.
当代人为什么需要它
Contemporary life is, surprisingly, saturated with 三世有法 assumptions. They're not framed that way — they're framed as "common sense" — but they're the load-bearing beliefs under a great deal of modern suffering and confusion. Once you notice them, you start to see them everywhere.
1. The personal brand and the curated continuous self. We curate a self intended to exist consistently across time. Photos from "the early days" should match the present self; the future self should look like the present self. Anxiety over "inconsistency" in a personal brand is anxiety over three-time existence — the worry that the self might come apart, might reveal 本有今无 or 本无今有 transitions that don't fit the curated narrative. The 涅槃经's view doesn't attack authenticity or self-presentation as such; it points out that the assumption of three-time continuous existence is what creates the anxiety in the first place.
2. Long-term planning built on present-self projection. When we sign up for a 30-year mortgage, plan for retirement, set a 10-year career trajectory, we implicitly assume the future self will reliably want what the present self wants, will be able to do what the present self can do, will inhabit a world resembling the present world. The 三世有法 assumption — that "I" exists across all this time, more or less as I am now — is so obvious it usually goes unquestioned. The 涅槃经's argument is not "don't plan"; it's that planning built on an unexamined three-time assumption will run into a 本有今无 wall eventually.
3. Fixed-identity claims. "I've always been X" — an introvert, a particular political orientation, a parent, an artist, a person of a certain faith. When the past-present-future identity is asserted as one continuous thing, any deviation starts to feel like betrayal or failure. 本有今无 becomes terrifying: "the me who used to be X isn't here anymore." But the actual lived record, examined honestly, often shows substantial transformations. Treating those as anomalies is treating the texture of reality as a problem.
4. Climate and civilizational denial. A collective-scale 三世有法 assumption: that civilization, ecosystems, weather patterns, social orders will continue as we know them. The future-self is imagined to inhabit a world resembling the present. The same argument structure applies, scaled up.
5. The archival / "everything is in the cloud" culture. Photos, social media, version histories, continuous backups — these infrastructures are designed to support a kind of three-time existence for our experiences. There's nothing wrong with them; but the sūtra points out what they often obscure: that the archive is not the experience, that "it will always be there" is an assumption that can fail in any of several ways, and that even within a continuous archive, what was experienced *then* is not what is experienced *now*.
6. Grief, loss, and the 三世有法 expectation. Most acute suffering around loss has a 三世有法 expectation embedded in it. "They should still be here." "I should still be able to do X." "This should still be the case." The teaching doesn't erase the pain. It offers a frame in which 本有今无 is recognized as the texture of how things are, not a wrongness to be repaired. This recognition doesn't take the ache away, but it can take away the secondary suffering — the suffering about the suffering, the conviction that the loss violates some cosmic law.
A contemporary angle worth flagging: digital memory technologies can paradoxically intensify the 三世有法 expectation. With photos, videos, voice recordings, social-media timelines, we have unprecedented capacity to "keep" things across time. But the experience of keeping a thing is not the experience of that thing being present. The file in the cloud is "there" in a sense; the lived experience of the moment captured is not there now. This is one of the more interesting contemporary sites where the 三世有法 / 本有今无 distinction becomes practically relevant.
A note on what contemporary science can and cannot say here: behavioral economics has documented that we systematically over-project present preferences onto future selves (a phenomenon sometimes called *projection bias*); neuroscience describes the constant turnover of experience — brain states that are never quite the same across time. These observations are not Buddhist teachings, and they don't "prove" 三世有法 无有是处; but they sit comfortably alongside it. The Buddhist argument here doesn't depend on any scientific finding; it's grounded in straightforward observation of conditioned phenomena, accessible to anyone willing to look.
常见误读与澄清
Misreading 1: "The sūtra is saying nothing exists at all." This is the most common error, and the most serious. The negation in the verse is highly specific: it's negating the proposition that dharmas exist across all three times *as a continuous existent*. It is NOT saying dharmas don't exist at all. Within any given moment, things DO exist. The teaching is not nihilism (否定存在); it's a refusal of a particular kind of permanence (否定遍三世的恒有). Read the negation carefully: it's "three-time existence has no ground," not "existence has no ground."
Misreading 2: "本有今无 means 'the past used to exist but doesn't anymore.'" Read in this trivial way, the verse becomes pointless (of course the past is "gone" — that's just what past means). The verse is actually pointing to a transition of the *same* phenomenon: something that was present in the prior state is no longer present in the present state. The object is continuous in being pointed-at, but its status has shifted from 有 to 无. That's the whole force of the verse — change of *one thing* across time, not the abstract disappearance of clock-time.
Misreading 3: "三世有法 is being positively taught here." It's not. It's the title of a refuted proposition. The sūtra's whole move is: this view has no 是处. Don't quote "三世有法" as if it were the Buddhist position. The Buddhist position, as the sūtra presents it, is that 三世有法 is 无有是处.
Misreading 4: Conflating with 诸行无常 (impermanence). Related but not interchangeable. 诸行无常 is a general principle: all conditioned things are subject to change. 三世有法, 无有是处 is a specific refutation of a specific view using observable change as evidence. The latter is one application of the former. If you substitute one for the other, you lose the precision of what the sūtra is doing here — it's not just saying "everything changes"; it's saying "the claim that something exists continuously across three times has no ground."
Misreading 5: Reading elaborate doctrinal schemes into the verse. The provided canonical excerpt is minimalist: just the verse, four times, with one word-order variation (in one of the four instances the order is 本无今有, 本有今无 — same content, reversed). The sūtra does not, in this material, classify past dhārmas separately from present or future ones; does not construct a three-time taxonomy; does not list specific examples of dhārmic factors; does not stage the refutation as a debate with named opponents. The argument is tight: 生灭变异 → 三世有法 无是处. Readers who want to add Sarvāstivāda-specific doctrinal categories or other elaborate frameworks onto the verse are welcome to do so in doctrinal analysis, but they should be honest that the verse itself is doing less work than those frameworks.
Misreading 6: "This is just a scholastic debate, no practical relevance." As the previous section tried to show, this view is silently embedded in many contemporary assumptions and anxieties. The teaching, internalized, can shift how we hold our plans, identities, relationships, grief, and self-projection. The "scholastic" and the "practical" are not as separate as they might appear.
Misreading 7: Treating 是处 as "place" or "location." It's a fixed rhetorical expression meaning "a place where this could stand" — i.e., a valid reason, a tenable ground. The verse is not asking "where in the universe does this happen" but "what justifies this claim." 无有是处 = "this claim has no justification."
Misreading 8: Reading the verse as a denial of continuity itself. It isn't. It's a denial of the specific claim that a dharma exists as one continuous existent across three times. Continuity of many kinds is observable; what is being contested is the particular metaphysical claim that "this dharma" exists past-present-future as one thing. The verse does not deny causation, memory, pattern, habit, karmic continuity. It denies a specific ontological claim about dhārmic existence.
Closing observation
What I find quietly powerful about this verse is how little it does. It doesn't construct a theory. It doesn't analyze the ontology of past-present-future. It doesn't list dhārmas. It points at two observable facts — things appear, things pass — and draws one tight conclusion: the claim that something exists across all three times has no ground.
That minimalism is a kind of respect. The sūtra trusts that the reader can see 本有今无 and 本无今有 in their own life, without needing elaborate framing. It trusts that, once these two are seen clearly, the inflated view of three-time continuous existence will quietly lose its grip.
The view it's dismantling — 三世有法 — isn't a dramatic heresy. It's the assumption underneath how most of us live most of the time: that "this" is going to keep being "this," that "I" is going to keep being "I," that "we" is going to keep being "we." Seeing that this assumption is doing more quiet work than we realized is, often, the actual moment of teaching.
