这个概念在说什么
相依 (Mutual Dependence) flips a quiet assumption most of us never examine: that things are "things" first, and then happen to relate to each other. The Madhyamaka reasoning in 《入中論善顯密意疏》 (Madhyamakāvatāra-bhāṣya) says the opposite — relationality is not something that happens *to* already-existing things; it is the very condition under which anything can be spoken of as "this" or "that" at all. The classical one-line definition goes: 诸法依待相关他法方得安立，于名言中假立为有，非自性成立 — "phenomena are posited only by depending on other relevant phenomena; they exist conventionally within naming, but are not established by self-nature (svabhāva)."
The negandum (所破) is precisely 自性成立 (svabhāva-siddhi) — the sense that something could stand on its own, fully itself, without needing anything else to be what it is. What is affirmed is not "nothing exists" but "things exist the way they do, namely, by way of name-and-convention (名言安立), and that is fully true at its own level." The text is explicit: "此中所破者为自性成立，并非否定名言中所安立之有."
This is the throughline, and it will recur in every pair below: 依待而假立 (dependent positing), 名言中有 (conventionally existent), 非自性有 (not self-established).
The Five Pairs — How Dependence Is Actually Structured
The commentary doesn't leave this abstract. It walks through five paired relationships, each showing a distinct way one thing's identity or status is borrowed from another. These deserve to be kept one-to-one — collapsing them into "everything is connected" loses the analytic edge the text is working to build.
(1) 支 / 有支 — Parts and Whole. A 瓶 (jar) and the 瓦礫 (clay shards / pieces) that compose it. The "whole-with-parts" (有支) gets its status as a whole only because there are parts (支); and those parts are called "parts" only because there is a whole to be parts of. The relation is structural and bidirectional.
(2) 德 / 有德 — Property and Property-Bearer. The jar and its 紺青花紋 (dark-blue pattern). The pattern (德) is a "feature"; the jar (有德) is the "feature-bearer." Strip the bearer and the feature has nowhere to live; strip the feature and the bearer is missing a dimension of what makes it this jar. The pair is about how attributes hang on the things that bear them.
(3) 貪 / 有貪 — Affliction and Afflicted Being. A 贪着可爱境之有情 (a being attached to attractive objects) and the 染爱 (fixated affection) that arises in dependence on attractive objects. The "having-greed" (有貪) and the "greed" (貪) are themselves a pair. The person is called "greedy" only because the greed is there; the greed is "their" greed only because there is a person. The commentary situates this pair within the broader framework of 漏 (āsrava, outflows/defilements) — the dependence is not just structural but conditioned by the very objects of attraction.
(4) 所相 / 能相 — Signified and Signifier. The jar and its 鼓腹、翻口、长项 (bulging belly, flared mouth, long neck). The jar is the 所相 (what is being characterized); the features are the 能相 (the characterizing features). These are the marks we use to recognize a jar as a jar. They depend on the jar; the jar as a recognizable *kind* depends on them.
(5) 能然 / 可然 — Burner and Burnable. 火 (fire) and 薪 (fuel). Fire is "fire-that-burns" (能然) only insofar as there is something burnable; fuel is "fuel" (可然) only insofar as there is something that can burn it. The pair names a functional relationship — neither is fire or fuel in isolation.
Taken together, the five pairs cover the range: composition (parts/whole), attribution (property/bearer), affliction (greedy one/greed), recognition (signified/signifier), and function (burner/burnable). "Being a thing" is always "being a thing *in some relation*."
The Bidirectional Crux
The commentary singles out 支/有支 for special emphasis because its dependence is manifestly 双依 (bidirectional): 既要依于支，乃能安立有支；亦要依于有支，乃能安立名为支. This is important because most philosophical complaints about dependence stumble on a residual picture where one side is "really" prior and the other is "derived." The text pushes back — neither side is the ground; the two are constituted by the relation. The same structure is then extended to all the other pairs: 德/有德, 所相/能相, 能然/可然 — all are 相依假立 (mutually dependent positing).
The Seven-fold Analysis at the End of the Line
The commentary then notes that even when one runs the seven-fold exhaustive inquiry (七相推求 — the standard Tibetan analysis into causes, parts, etc.) and finds nothing graspable as a self-establishing essence, the thing can still be conventionally posited. This is the crucial split: 由世间名言而立，非由观察实义正理所成立 — "established by worldly naming, not by reasoning that grasps ultimate reality." Conventional existence is not a degraded form of real existence; it is the only kind of existence there is, and the text is explicit that this is not being denied.
Cause and Effect as 相依
The commentary extends the same logic to 因 (cause) and 果 (effect). 能生果者方可名为因 — only what can produce an effect is called a cause; 果亦须有因，乃能说是从彼而生 — the effect only counts as such because there is a cause. They are not first established separately and then related; they get their names and their status from the relation itself.
The text sharpens this with a small regress: 若因自性有，说因居先仍须等待果，方成其为因；若说果居先，则成为无因之果. If causes were self-established, then a cause said to "come first" would still have to wait for the effect to qualify as a cause; if the effect came first, you'd have a causeless effect. Neither order sustains self-nature. Cause and effect, too, are 相依, 相待, 假立, 非自性有.
Where This Sits in the Path
相依 is the analytical machinery beneath the famous 缘起性空 principle (dependent origination, empty nature). The well-known verse from Nagarjuna's 《中論》 (Mūlamadhyamakakārikā, ch. 24) expresses the same logic: "以有空义故，一切法得成；若无空义，一切则不然" — "Because of empty-nature, all phenomena succeed; without empty-nature, nothing would succeed." 相依 is what that line is pointing at: things "succeed" (得成) precisely because their identity is borrowed, not self-standing. The five pairs are not the destination; they are the training that prepares the practitioner to see this directly. In the overall vehicle of liberation, 相依 sits within the 智慧 (prajñā) branch — right-view analysis — that clears the way to a direct realization of emptiness (空性). It is the conceptual pre-flight, not the landing.
生活里的走查
The risk in any application is mapping Buddhist categories onto modern life too loosely — "we're all connected," "everything is interdependent" — which sounds warm but loses the analytic edge. The classical concept is more precise: it's about how specific identities get *borrowed* from specific others. Each scene below maps to a specific pair, not to "interdependence" in general.
早晨通勤 (Morning Commute)
You are on a crowded subway. The person next to you is "a stranger" — recognizable by 能相 markers (youth, suit, earbuds, that particular posture); you are "a passenger" — the 所相 bearer of those markers in this arrangement. The identity "passenger" exists only because there is a "train," a "route," a "destination," a "ticket system." You are not "a passenger" in your kitchen. Lift the system and the identity dissolves. This is the 所相/能相 pair in action.
Now imagine the inner complaint: "people are so rude." The "rudeness" (德) and the "rude person" (有德) are also a pair. The person is rude *in this context* — close quarters, sleep-deprived city, the unwritten protocol of averted eyes. The 德 does not sit underneath the bearer like a permanent attribute; it is a function of the situation. (This is the classic error of treating a property as if it were the substance of the thing — see below.)
刷手机里的推荐流 (Scrolling the Feed)
Open an app. The "feed" feels like a thing — you tap it, swipe it, complain about it. But the feed is a 支/有支 situation: data points, ranking algorithm, time of day, your prior history, the platform's business model, the advertisers' bids. The "feed" you see is a whole constituted by these parts; and the parts are "the feed's parts" only because there is a feed to be the feed's parts. The functional pair 能然/可然 is also live: the algorithm (能然) "burns" (operates on) your preference data (可然); the data is "preference data" only because something is burning it.
Here is where contemporary experience amplifies the classical point. The algorithm is not a "self-established thing" — it is a relational configuration that emerges from data + model + objective function + user interaction. Remove any leg and the whole thing reconfigures or disappears. We experience the feed as if it were the world; the analysis reveals it as a 相依 whole. The 德/有德 pair is also doing work: the "addictive quality" (德) and the "platform" (有德) are co-arisen. The platform is addictive *in* the configuration; the configuration is the platform.
加班与咖啡 (Overtime and Coffee)
You're on your fourth coffee. The "fourth coffee" exists as a category because of: a workday, an employer's expectation, your own exhaustion, prior coffees, a culture that binds stimulant-use to productivity. The cup is the 能相 feature; your Tuesday-night self is the 所相 bearer. Strip the culture and the cup is just hot water in a vessel. Strip the exhaustion and the cup is not "needed." This is the 德/有德 pair: the bearer (you, tonight) and the property (caffeine-dependence) are co-arisen — and the cause-effect analysis is also here: the work shape (因) and the exhaustion (果) are mutually constituting, not separately fixed.
亲密关系 (Long-Term Relationship)
Long-term partnership. The cultural whisper is "we have grown together" (我们一起成长了). The classical analysis is sharper: the "self you were before the relationship" is itself a 相依 construction, and the "self you are now" is a different 相依 construction that has incorporated the other into its parts. The "partner" (有支) is also a part (支) of a new whole (the relationship); and the new whole is what makes either of you legible as "partner." The 德/有德 pair applies: the property of "being supportive," say, is not a thing inside the partner; it is how the partner functions in this whole.
Where contemporary psychology tends to say "you complete each other," the Buddhist analysis says something more rigorous: you are each constituted by the relation; without the relation, neither of you is the same "you." That is not a sentimental claim; it is a description of how identity is built. The 有貪/貪 pair, generalized, applies to attachment itself: the "attached one" and the "attachment" are co-arisen. The very "you" that is attached is configured by the attachment.
育儿 (Parenting)
A toddler cries at separation. The "child" and the "parent" are constituted by the 支/有支 and 德/有德 pairs continuously: child-ness is a relation to a parent, and parent-ness is a relation to a child. The relation is not always pleasant, but it is the structure of "child" and "parent" as identities. The 能相/所相 pair is also active: the markers (crying, clinging, the small backpack, the school uniform) are how we recognize "child" by; the child is the bearer of these markers.
A common mis-mapping here is to read 相依 as "you need each other" — need as psychological need. The classical concept is more structural: the identity itself is borrowed. That is a different, more radical claim, and it has very different implications for how one thinks about the painful parts of caring for someone.
The General Mapping Snag
Most contemporary readers, before the analysis walks them through, will map 相依 onto "social/relational needs." That is the wrong pair. 相依 is about how the identity *of anything at all* is borrowed, not about how humans depend on humans. The five pairs span the entire range of how things come to be identified — jars, patterns, afflictions, features, fires — and only one of them is even close to the relational sense. The danger of the sentimental mapping is that it leaves the deeper claim — *all identification is borrowed* — unexplored.
当代人为什么需要它
The contemporary condition has a few features that make 相依 less like an academic topic and more like a piece of medicine.
Identity inflation. We live in a culture that constantly asks "who are you, really?" — and offers a menu of essences (your personality type, your values, your career, your trauma, your politics, your attachment style). This is self-nature establishment in everyday dress. 相依 doesn't deny that you have a personality, a job, a history; it denies that any of these is the "real you" that stands independently. The practical benefit is that fixed identity claims loosen — not into nihilism, but into the freedom to change. You are not your burnout; you are not your job title; you are not your worst decision. Each of these is a 德, not a self.
Performative selfhood on social media. The "feed" example isn't just a scene — it's the dominant metaphysical training most of us get every day. We are taught to be a whole (有支) made of curated parts (支): photos, captions, opinions, lifestyle markers. The feed whispers that the whole is self-established: "this is me." 相依 lays this bare: the "me" is a relation between the app, the audience, the algorithm, the moment, the past self. Once you see this, the feed's tyranny drains out a little — not because the feed is unreal, but because it is not the substance of who you are.
Burnout and the cause-effect story. We tell ourselves "I am burned out because of work" — and the cause becomes a fixed thing, the effect becomes a fixed thing, and the relation is solid. 相依 reveals that the relation is exactly what makes either of them "work" or "burnout." Reframe the work (different role, different hours, different meaning) and the burnout reconfigures. The classical analysis refuses to let either pole be reified, and that re-framing is itself a small freedom.
Conflict in intimate relationships. Couples often argue as if each partner had a self-standing set of traits ("you are selfish") and the conflict were a collision of two fixed natures. The 有貪/貪 pair, generalized, says: the property you are fighting about is co-arising with the bearer. Change the property's conditions, and the bearer looks different. This is not blame-shift; it is a different metaphysics of who people are. It also gives some purchase on the experience of "she is so different with other people than with me" — of course she is; the 能相/所相 is being co-arisen differently in different contexts.
Algorithmic anxiety. When we talk about algorithms as if they were self-established agents ("the algorithm decided," "the algorithm is biased"), we are reifying. The 德/有德 pair is helpful: the algorithm is what it is, in the way it is, because of the data, the objective, the deployment, the user. The interesting question is not "what is the algorithm, really?" but "what is the algorithm in relation to?" That is a 相依-framed question, and it leads to more accurate diagnoses than treating the algorithm as a metaphysical object.
A note on the analogy. It is tempting to say "neuroscience shows that the self is a constructed process" or "AI research shows that outputs are relational." These contemporary references are useful as *pointers* but they are not the same as the Buddhist analysis. The brain has constructive processes; whether the self is thereby "self-established or not" is a metaphysical question the neuroscience alone cannot answer. Likewise, large language models produce outputs in dependence on training data and context; this is a structural resemblance to the 能然/可然 pair, but it does not prove the pair. The analogy is illuminating in the way a metaphor is illuminating — it points. It does not equate.
The concept is useful, in short, because it offers a way of seeing things that resists the two dominant modern errors: reification (treating relations as if they were essences) and nihilism (treating nothing as if it were real at all). 相依 holds the middle: things are real as relations, and the relations are real as conventional positing.
常见误读与澄清
Misreading 1: "相依 = 缘起, so it's just the doctrine of dependent origination."
The most common confusion. 缘起 (pratītyasamutpāda, dependent origination) and 相依 are tightly related but not identical. 缘起 is the broader principle that phenomena arise in dependence on conditions — a positive description of how things come to be. 相依, as discussed in the commentary, is more specifically about the *positing structure* of identity: how the very labels we use, and the identities they pick out, are constituted by their relations to other labels and identities. 相依 is a moment within the larger 缘起 analysis, sharpening it: not just "things arise dependently" but "the identity of things is dependent on the identity of other things." Conflating them flattens the analytic edge. The commentarial passage in 《入中論善顯密意疏》 is precisely about that sharpening — taking the everyday notion of conditional arising and pressing it into the structure of how we name things.
Misreading 2: "If things are not self-established, then they don't exist."
The classic nihilist mis-step, and exactly what the text pre-empts: "此中所破者为自性成立，并非否定名言中所安立之有." What's being refuted is self-nature establishment, not the existence of things in conventional naming. The jar is on the table. Your morning is real. 相依 says these are real as relations and designations, not as self-standing essences. To convert "not self-established" into "not real" is to introduce a metaphysical commitment the text explicitly refuses. This is the difference between 相依 and the vulgar nihilism that the text's tradition is constantly defending itself against.
Misreading 3: "相依 = everything is connected, so we should be kinder to each other."
The slippage from "structurally co-arisen" to "morally implicated." The classical concept is not a moral injunction; it is an ontological description. Whether one *should* be kinder is a separate question, and it does not follow automatically from the structural fact. The text is more rigorous: identity is borrowed, but it does not automatically give you any particular obligation. A different Buddhist analysis, on compassion (慈悲), does that work — and it does so by going through further stages of the bodhisattva path, not by resting on 相依 alone.
Misreading 4: "相依 = mutual psychological need."
Especially in modern self-help, 相依 can sound like "we need each other to be whole." This is the 有貪/貪 pair being misread. The classical analysis is that the "greedy one" (有貪) and the "greed" (貪) are co-arisen, but the commentary's broader project is precisely to dismantle the sense that this is a fixed or essential relation. The point is not that you should need each other; the point is that the "you" that needs is itself a relational configuration. The Mandarin "相依" in everyday Chinese (mutual dependence, leaning on each other) carries precisely this sentimental undertone — and the Buddhist technical term is being used in a far more austere sense. The everyday sense is not wrong; it is just incomplete. The classical sense goes further: the "you" doing the leaning is also borrowed.
Misreading 5: "If cause and effect are 相依, then there is no cause and effect."
The commentary's concern is the opposite. 因果虽可依名言安立，却不能被说成以自性成立 — cause and effect can be posited in conventional naming, but cannot be said to be self-established. The names are real, the operations are real, the consequences are real. What is denied is that "cause" and "effect" are self-subsistent categories that exist prior to any relation. The advice is not to abandon causal thinking; it is to abandon the metaphysics of causal essence. A clinician who understands that "burnout" and "work" are co-arisen is still a clinician who treats burnout as arising from work.
Misreading 6: "相依 = relativism, or 'any reading is valid.'"
Because the text says things are "established by worldly naming," it can sound like a license for any interpretation. The text itself is clear: the naming is not arbitrary; it works because it tracks the actual relational structure of things. A jar is conventionally a jar because the parts (支) and the whole (有支) actually relate in the way they do. To say "this is a jar" wrongly is not the same as saying "this is a jar." Conventional positing in the Madhyamaka sense is not personal preference; it is intersubjective, linguistically constrained, and materially anchored. The text is not a license for "your truth / my truth" — it is an analysis of how shared linguistic and material convention works, and where its limits are.
Misreading 7: "相依 means we should dissolve all distinctions."
The text does not say distinctions are unreal. It says distinctions are conventionally posited, by dependence. Distinguishing jar from pot is a real and useful operation; it just is not the discovery of self-established essences. The Buddhist path is not the erasure of distinctions (which would be incoherent — you would have to distinguish the erased from the non-erased) but the seeing-through of distinctions to their borrowed nature. The five pairs preserve distinctions even as they dismantle self-nature. Distinction without reification is the goal.
Misreading 8: "相依 = 平等 (equality / sameness)."
Because the pairs are "mutually dependent," it can be read as "A and B are equal" or "A and B are the same kind of thing." The text is not making a moral or ontological claim of equality; it is making a structural claim about reciprocal constitution. The jar and the clay shards are not equal — they are different — but neither is self-subsistent. The dependence is between different things, not between same things. The reciprocal constitution is structural, not egalitarian.
A closing note on the larger frame. 相依 is part of the 甚深见 (abhidharma-style deep view) of the Mahāyāna path. It is the analysis that supports the realization of 空性 (emptiness of self-nature), and that realization, in turn, is what cuts through the subtle reification that keeps beings wandering. The five pairs are not the destination; they are the training wheels. The destination is the direct, non-conceptual seeing of how things actually are — borrowed, clear, and free of the metaphysical inflation that the word "self-nature" smuggles in. Used well, 相依 is the equivalent of removing a stained-glass window you thought was the sun: the room is darker for a moment, and then the actual light comes through.
