What this concept is about
"展轉" literally means "to unfold and turn, one after another." Picture a folding screen being opened panel by panel: each panel, once extended, becomes the hinge that lets the next one swing further, and the entire screen never returns to its folded state on its own. 展轉力 names exactly this dynamic — the **power by which a chain of causes and conditions (因緣) keeps handing its energy forward, with each link not merely continuing but actually *amplifying* what came before**.
In the classical Abhidharma and Yogācāra analysis (especially the 瑜伽師地論 *Yogācārabhūmi Śāstra* and its commentarial tradition), 展轉力 is one of the eleven forces (力) that explain how action (業) unfolds into consequence over time. It is distinguished from its close neighbors in a precise way:
- 業力 (karmic force) is the latent charge stored in a completed action — what the karma "is" as a seed. - 增上力 (ascendant / dominant force) is when one particular factor in a situation dominates or steers the others (e.g., a king dominates a court; a strong wind dominates a sail). - 展轉力 is neither a single seed nor a single dominant factor, but the *running chain itself* — the way each consequent becomes the condition for the next, and each link in the chain raises the volume of what follows.
The classical phrasing 「諸因緣相續遞相增上」 carries three load-bearing words that must be kept distinct:
1. 諸因緣 (numerous causes and conditions) — plural, multi-stranded. 展轉力 is never a one-cause-one-effect story; it is a web of conditions interlocking. 2. 相續 (continuous) — uninterrupted. The chain does not "rest" between links; the flow itself is part of the force. 3. 遞相增上 (sequentially augmenting one another) — this is the heart of the concept. "遞相" means *each one in turn*; "增上" means *raising what came before*. A mere sequence (A→B→C) is not yet 展轉力. The defining mark is that B does not merely follow A, B raises A's effect; C raises B's; and so on, so the system is on a curve, not a line.
Where does this sit in the map of the path to liberation (解脫道)? 展轉力 is the *mechanism* that makes both samsara and progress self-reinforcing. The 十二因緣 (twelve links of dependent origination) — ignorance → formations → consciousness → name-and-form → the six sense bases → contact → feeling → craving → clinging → becoming → birth → aging-and-death — is itself a textbook exhibition of 展轉力: each link conditions the next and amplifies it, which is precisely why a being caught in the cycle does not naturally fall out of it. Conversely, the same principle explains why the first faltering steps of practice (初發心) gain traction over time: a moment of mindfulness, held, becomes easier mindfulness, becomes a baseline, becomes character. The Buddha did not need a separate set of laws for awakening — he pointed to the same 緣起 (pratītyasamutpāda, dependent origination) that runs samsara, but turned in the other direction.
So 展轉力 is, in essence, the physics of how dependent origination behaves over time: nothing exists in isolation, every condition hands its energy to the next, and the cumulative trajectory is what carries a being — either downward into denser suffering or upward toward release. This is why the early Buddhist analysis of karma could never be reduced to a simple ledger of debits and credits; karma is *generative*, and 展轉力 is the name for its generative power.
Walking through it in daily life
The clearest way to *see* 展轉力 is to watch a small pattern — one most contemporary readers will recognize immediately — unfold over weeks. Let's use a familiar chain: late-night short-video scrolling.
Week 1, the seed. You open an app "just to check one thing" before bed. The first clip is mildly interesting. You feel a small lift of novelty (初始因緣). Nothing dramatic; you close the app after ten minutes and sleep fine.
Week 2, the first augmentation. Because that small lift felt pleasant, the next night your hand reaches for the app more readily — there is now a tiny memory-trace of reward (相續 begins). You stay twenty minutes. The brain's dopamine circuitry has been "primed" by repetition, not destroyed. Each click delivers a smaller micro-reward, but the *chain* is growing.
Week 3, the platform joins in. Your behavior — two consecutive nights of long sessions, a pause on certain categories — has now become data the algorithm uses to push harder (諸因緣 now includes the external system). You are not being acted *on*; you and the algorithm are mutually augmenting one another (遞相增上). Your evening preference shapes its recommendations; its recommendations shape your evening preference.
Week 4, sleep and mood degrade. Tired in the morning, you drink more coffee. Caffeine at night makes it harder to sleep, which makes the phone easier to reach, which deepens the loop. The chain is now self-supporting: each link *raises* what came before. Sleep loss raises screen use; screen use raises sleep loss. This is 展轉力 in plain sight.
Three months in. The "small late-night pleasure" has become a structural feature of your evenings. A friend suggests you stop; you try and find that your hand and your attention have been trained — by you, by the algorithm, by caffeine, by fatigue — into a groove so deep that breaking it feels like resisting a current. The current was not handed to you from outside; it was built, link by amplifying link, by the chain itself.
This is exactly the classical picture of 展轉力, mapped onto modern life. The crucial point: none of the individual links in this chain is, by itself, the "problem." The ten-minute video isn't evil; the second cup of coffee isn't evil; the algorithm isn't evil. The force lives in the *relationship between the links* — the way each one hands its energy forward and amplifies what came before. This is why willpower aimed at a single link often fails; you are pulling one stone out of an arch where every stone is bearing the weight of all the others.
Now walk the same architecture in a constructive direction: daily meditation, starting with five minutes.
Day 1. Slightly awkward; thoughts are loud; you feel you are "bad at it." (Initial 因緣, weak.)
Day 7. You have noticed one or two moments of relative calm during the day that you would have missed before. The noticing itself is now a small reward — not pleasure exactly, but a felt sense of *being a little more here*. The chain gains its first augmentation.
Day 30. The five-minute sit is no longer the hardest part; the harder part is making sure you don't skip it. You have a felt continuity (相續). Some evenings you extend to ten minutes because the five felt too short.
Day 90. A small but real change in baseline stress reactivity is noticeable to people around you. Each session now reinforces the next more strongly than the last — *遞相增上* in the upward direction. The "augmenting" quality of the chain is identical in structure to the video-scroll case; only the direction has been chosen.
A year in. A pause before reacting in a difficult conversation — something that would have required effort at month one — now happens somewhat automatically. You have not become a different person; you have built a self-reinforcing loop in a different direction. This is the same force the early contemplatives described; it does not need a metaphysical special case to produce liberation-grade transformation, only a series of deliberate initial conditions held long enough to gain their own momentum.
Mapping precisely to the classical definition: - *諸因緣* = body posture, breath, the room, the day's residue, the teacher/text/audio guiding you, the prior sessions — a whole web of conditions, not a single cause. - *相續* = unbroken chain; missing a day does not destroy it but weakens it, because continuity is constitutive of the force. - *遞相增上* = each session slightly easier to begin and slightly deeper in effect than the last, because it is building on the prior session's traces.
The mapping that people most often get wrong: they reduce 展轉力 to "habit" (習慣). Habit is a much thinner concept — it says behavior repeats. 展轉力 says behavior *repeats and amplifies*, and that the amplification comes from the relationship between successive links, not from any one of them alone. A habit can sit flat; 展轉力 cannot — it is, by definition, a curve.
Why contemporary people need this concept
Three reasons this classical idea is unusually useful to a modern reader.
1. It corrects a default modern metaphysics of "isolated events." Most contemporary self-improvement language — and a lot of popular psychology — treats each choice as a discrete unit: one good decision, then another, scored on a tally. 展轉力 says the *trajectory* is the reality. The scoreboard is an artifact; the curve is the truth. This reframing matters because it explains two things the linear view cannot: (a) why small beginnings are not small for long, and (b) why you cannot think your way out of a chain you are physically inside of. The recognition "I am in a self-reinforcing loop" is itself a precondition for breaking it, because it tells you where to apply leverage — at the joint, not at any single link.
**2. It dissolves the comfort of "this was caused by *them*."** In an algorithmic, networked, attention-economy environment, the web of conditions producing any given behavior is dense and partly outside the individual. 展轉力 honors this — *諸因緣* genuinely is plural, including systems — without letting it become an excuse. The classical analysis is strikingly non-victim-blaming *and* non-deterministic: the chain has momentum, but chains are made of links, and links can be interrupted. The liberation the Buddha points to is not a miracle; it is a new chain started early enough, and held with enough continuity, that the old chain loses its grip. That is an extraordinarily practical and liberating metaphysics for anyone who feels structurally caught.
**3. It puts the *direction* of the chain on the table.** Once you see that chains self-augment, the urgent practical question becomes: *which way is this one curving?* Not "is this good or bad?" in the abstract, but "is this amplifying toward more suffering or toward more freedom?" That is a question you can answer for any concrete situation in your day — the evening scroll, the argument with your partner, the work habit, the way you speak to your child after a hard day. The question is not "should I be a better person?" The question is "is the chain I'm in right now curving upward or downward, and what is the next link going to be?" That question is answerable, and answering it repeatedly is itself a chain that curves the right way.
It is worth being honest about the limits of any cross-domain analogy here. Contemporary neuroscience describes something analogous — reinforcement learning, the way repeated reward signals strengthen synaptic pathways, the way habit loops consolidate in the basal ganglia — but neuroscience has not, and cannot, claim to have "proved" 展轉力. The frameworks overlap; the Buddhist analysis is about the *meaning and ethical trajectory* of the chain, which is not what neural models are designed to address. The similarity is suggestive, not confirmatory. Holding that distinction with care is part of using the concept maturely.
Common misreadings and clarifications
Misreading 1: "展轉力 = cause and effect." Not quite. Cause and effect (因果) is the basic fact that this follows from that. 展轉力 is the *dynamic, self-augmenting* character of how causes and effects *chain together over time*. Without 展轉力, karma would be a static ledger; with it, karma is a running engine. The translation "power of chain reaction" captures this better than "cause and effect" does.
Misreading 2: "It's just momentum / 慣性." Close, but momentum in physics conserves what is already there; it does not *augment*. A rolling ball slows. 展轉力 specifically includes 增上 — *increase* — at each step. A better English is "mutually reinforcing momentum," or in contemplative language, the way a tendency tends to become *more itself* the longer it runs. This is also why the destructive chains in samsara do not simply decay; they intensify, which is exactly what the classical analyses of addiction, resentment, and ideological hardening describe.
Misreading 3: "It means good deeds and bad deeds both keep multiplying, so everything is fated to escalate." No — the concept is value-neutral about *what* is being augmented. It applies equally to the chain of resentment that hardens into cruelty and to the chain of patient kindness that softens into reliable love. The classical tradition's point is precisely that this is why deliberate initial conditions matter so much: the chain will do the rest. The same physics makes small beginnings of practice more consequential than a naive ledger-view of karma would suggest.
Misreading 4: "It's the same as 增上力." A frequent confusion because both contain 增上. They are neighbors in the eleven-fold classification for a reason, but they are not the same: - *增上力* is *one factor dominating or supporting another within a situation*. (The soil dominates the seed's growth; the teacher's presence dominates a beginner's capacity.) - *展轉力* is the *sequential mutual augmentation across time* — A→B→C where each step amplifies the prior. Think of 增上力 as a *vertical* relationship (one factor on top, supporting or overruling another in the same moment), and 展轉力 as a *horizontal/temporal* relationship (one step handing its energy to the next, across time). They cooperate constantly — every link in a chain of 展轉力 is also a site of 增上力 — but the perspectives are different.
Misreading 5: "Once a chain is going, it cannot be redirected." The opposite is closer to the Buddhist claim: chains *can* be redirected, but only by starting a competing chain early enough that it has its own momentum before the old one finishes. This is why the contemplative traditions put enormous weight on the very first moments — the first breath after anger arises, the first thought before the second drink, the first small honest word in a long dishonest pattern. The old chain is not defeated by argument; it is outrun. This is the practical heart of why 展轉力 is a hopeful concept for practitioners, not a despairing one for samsara: the same force that drags you down can be turned around, and once turned, it does most of the work of carrying you up.
A closing image, in keeping with the spirit of the concept: a small stream entering a valley will, given time, carve a canyon — not by any single surge of water, but because every drop hands its energy to the next drop, and the channel itself becomes the engine of further flow. The Abhidharma contemplatives, watching the same process in the inner life of attention and karma, gave it a name: 展轉力. The name is short; the canyon it describes is the whole of a human life, and the whole of the path.
