一、這個概念在說什麼
If you have ever asked yourself, "Why does doing *this* seem to pull me toward *that*, while doing something else pulls me toward something else entirely?" — you are already asking the question that the pair 順逆 (*shùn–nì*, conforming–opposing) was built to answer.
In the Abhidharma tradition, and especially in the 《阿毘達磨俱舍論》 (*Abhidharmakośa-bhāṣya*, Treatise of the Treasury of Abhidharma), these two characters are not moral labels. They are relational and directional terms. They describe how one *dharma* (a phenomenon, a factor, a cause) fits with another: whether it harmonizes, supports, gives rise to, and "tends toward" its counterpart — or whether it clashes with, turns away from, and works against it.
- **順 (*shùn*)** — to *conform with*, *accord with*, *give rise to*, *correspond to*. One dharma fits another like a key fits a lock, like a current fits a channel; it *helps that other dharma come about*. - **逆 (*nì*)** — to *go against*, *turn away from*, *depart from*. One dharma clashes with another; it *obstructs or undermines its counterpart*.
The pair is, in the *Kośa*, often compressed from the fuller forms 隨順 (*suíshùn*, conforming with) and 違逆 (*wéinì*, opposing). The single-character shorthand is a stylistic feature of this treatise, where 順 and 逆 enter into dozens of compound technical terms.
Crucially, 順 is not the same as "good," and 逆 is not the same as "bad." The pair is about *causal fit and trajectory*. Whether a conforming trajectory is wholesome or unwholesome, liberative or worldly, depends entirely on what is being conformed *with*. This is why the *Kośa* does not just talk about 順 vs. 逆; it talks about *what* one is conforming to or opposing, and at what level of depth.
Three Classical Contexts Where 順逆 Operates
1. Karma and the Feeling It Ripens Into — 業與受之順
The first major application is the most familiar: how a karma (karma, action of body, speech, or mind) *conforms with* the vipāka (retribution, ripened result) it tends to produce.
The *Kośa* verse is stark:
順樂苦非二，善至三順樂， 諸不善順苦，上善順非二。
In plain terms: wholesome karma of the desire realm conforms with the arising of pleasant feeling (*sukha-vedanā*); unwholesome karma conforms with painful feeling (*duḥkha-vedanā*); the "upper" wholesome karma — that is, the 不動業 (*acalanī karma*, "immovable action" of the form and formless realms) — conforms with feeling that is *neither pleasant nor painful* (*adukkhamasukha-vedanā*, the neutral feeling of deep samādhi). Some readings extend the third case to additional categories of middle-level good karma as well, because their intermediate vipāka is also neutral.
The deeper point comes when the treatise breaks 順受 (*shùnshòu*, "the conforming reception," i.e., the way a feeling "fits" or "matches" its cause) into five facets: 自性差別 (by its own nature), 相應差別 (by associated mental factors), 所緣差別 (by its object), 異熟差別 (by the ripened result itself), and 現前差別 (by its current, manifest arising). Karma "conforms with" feeling along all five axes simultaneously — and a feeling is not just a label of "pleasant/unpleasant," but a multidimensional resonance with what produced it.
What this means, before we apply it: **the way you feel right now is not random; it is in a relationship of *fit* with what you have been doing.** Whether that fit is pleasant, painful, or neutral depends on the kind of action.
2. Three "Conforming" Goods — 三順之異
The second application refines the meaning of 順 further. *Wholesome* action is not one thing; the *Kośa* divides it into three kinds, all described with the word 順, because each is *conforming with a different goal*:
順福順解脫，順決擇分三， 感愛果涅槃，聖道善如次。
- **順福 (*shùnfú*) — "conforming toward merit."** Wholesome acts such as giving (*dāna*), ethical conduct (*śīla*), and meditation-of-a-certain-kind (cultivation, *bhāvanā*, in its worldly register). This conforms with 愛果 (*ai guǒ*) — the "beloved fruit" of human and heavenly rebirth. It produces the kind of happiness that the desire realm can offer. - **順解脫 (*shùn jiětuō*) — "conforming toward liberation." Wholesome acts done in the spirit of freedom from saṃsāra, oriented to 涅槃果** (*nirvāṇa guǒ*), the fruit of nirvana. - **順決擇分 (*shùn juézé fèn*) — "conforming toward the decisive determination," i.e., the four ārya-path preparations: 煖 (*uṣmagata*, heat), 頂 (*mūrdhan*, summit), 忍 (*kṣānti*, patience/acceptance), 世第一法 (*laukikāgradharma*, supreme worldly dharma). This is wholesome action that belongs to the 聖道善** (*shèngdào shàn*, the goodness of the noble path) itself.
The verse's move is subtle but pivotal: **the word 順 does not change, but what it conforms *with* shifts from worldly happiness to liberation to the path of seeing.** The directional logic is identical across all three — a wholesome action *leans toward* its ripening — but the *altitude* of what it leans toward differs. This is the framework's hidden depth: a single word must do work at three different elevations.
3. Concentration's Two Directions — 定之順逆
The third context is where 順逆 appear most explicitly as a *paired* pair, not just as a single word with compounds:
二類定順逆，均間次及超， 至間超為成，三洲利無學。
In meditative attainment (等至, *samāpatti*, "equal-arising"), there are two classes of concentration experiences: one conforming upward (順趣上界, ascending toward higher form or formless realms) and one opposing and falling downward (逆墮下界, descending away from them). Both movements can be gradual (次第經歷中間地, *jiàn cì jīnglì zhōngjiān dì* — passing through each intermediate stage in order, 間次) or leaping (超, *chāo* — bypassing intermediate stages). The meditators capable of the leaping attainments are 無學利根 (*wúxué lìgēn*) — āryas of sharp faculties, learners who have completed their training — residing in any of the three continents (excluding the northern continent of Uttarakuru).
The conceptual point is plain: even in samādhi, which feels like one undifferentiated "good state," there is direction. Some meditative states *lean toward* higher states; others, despite being meditative, *lean back* toward lower ones. The label "concentrated" tells you nothing about altitude; you must ask, "Conforming toward *what*?"
A Note on Terminological Form
Across the *Kośa*, 順 and 逆 combine with verbs in revealing patterns. 順 walks with 感 (*gǎn*, to feel/rippen), 引 (*yǐn*, to draw forth), and 生 (*shēng*, to give rise to) — it is generative, productive, leaning-forward. 逆 walks with 背 (*bèi*, to turn one's back on), 違 (*wéi*, to violate or be contrary to), and 墮 (*duò*, to fall) — it is divergent, receding, falling-away. This verbal company is itself a definition: 順 is the verb that points to what is *drawing toward*; 逆 is the verb that points to what is *falling away from*.
二、生活裡的走查
I want to walk through a single week with a person — let's call her M. — and trace, by the classical definitions above, where 順 and 逆 are quietly operating. M. is not a Buddhist practitioner; she is a project manager in her thirties, a parent of one child, with a long commute and a tighter sleep window than she would like. Almost every moment below is hers, or someone close to hers.
Monday morning, 6:40 a.m.
The alarm rings. M. has two choices that she has made automatic over the years: snooze for twelve minutes and scroll her phone in bed, or get up and start the kettle. Most days she snoozes; she tells herself she is "easing into the day."
By the karma–feeling framework above: snooze-and-scroll is a small unwholesome action of body and mind — it 違逆 (*wéinì*, goes against) the natural rhythm of wakefulness her nervous system is offering her, and 順 (*shùn*, conforms) with a felt state of low-grade heaviness that will follow her into the 9 a.m. meeting. In vipāka terms: this small action conforms with 苦受 (*duḥkha-vedanā*) — not acute pain, but the heavy, slightly-withdrawn feeling-tone that will color her first two hours.
The hot path — get up, kettle on, three minutes of stillness before the day begins — is not a *great* practice; it is barely 順福 (*shùnfú*, "conforming toward merit"). But by the *Kośa*'s grammar, it is a wholesome action of the desire realm that conforms with a pleasant feeling-tone: a kindlier 樂受 (*sukha-vedanā*) that will ride under the morning.
The common mapping mistake here: people assume "small action → small consequence." The classical framework says the action *conforms with a particular kind of feeling*, and the feeling-tone shapes everything downstream. A year of snooze-and-scroll is not twelve minutes a day wasted; it is a thousand tiny conformings with a slightly numbed state.
Tuesday, 1:15 p.m., lunch with a colleague
A colleague, J., complains about another teammate in a way that is sharp, partly unfair, partly justified. M. has a flash of irritation — *yes, exactly* — and joins in for forty seconds, then stops. She notices the irritation has a tail.
By the 業與受之順 framework: the forty seconds of joining-in 順 (*conforms with*) a specific kind of vipāka — what the *Kośa* would call 相應差別 (*xiāngyìng chābié*, "differentiation by associated factors"). The action does not stand alone; it carries a cohort of mental factors — irritation, a small tightening of self-image, an "us vs. them" frame — that together conform with a particular felt state, not a single feeling but a *constellation* of feeling that will color her afternoon calls.
What M. does in the next breath is the more interesting move. She says, "Yeah, I notice I want to be on your side about this. Let me not be, for a minute." She does not perform a Buddhist practice; she interrupts the conforming. The interruption is itself an action — and by the framework, it is conforming with a different vipāka: the openness of *not yet having taken a side*.
This is also where the 五種差別 (*wǔ zhǒng chābié*, five-fold differentiation) of 順受 comes alive. The interruption changes 所緣差別 (*suǒyuán chābié*, "differentiation by object") — the object her mind is leaning toward; 相應差別 — the cohort of mental factors rising with it; and 現前差別 (*xiànqián chābié*, "differentiation by manifest arising") — what is actually showing up *right now* in awareness. She has, in the *Kośa*'s language, redirected the river mid-flow.
Wednesday evening, 9:30 p.m.
M. sits on the floor next to her child's bed while the child falls asleep. Her phone is in her hand; the child's hand is in hers. She chooses to put the phone face-down on the rug and stay.
This is a textbook case of 順福 (*shùnfú*, conforming toward merit). It is wholesome action in the desire realm — generosity of attention, the basic moral goodness of *being with what is in front of you*. By the verse quoted above, this action 感愛果 (*gǎn ài guǒ*) — it conforms with a *beloved fruit* — the warmth, the relational bond, the human happiness that will be both M.'s experience tonight and her child's memory twenty years from now. It does not need to be exalted to count. 順福 is not a lesser category; it is the category of genuinely good human life.
Where people misread: they often treat 順福 as a "lesser" path compared to 順解脫, and then skip it on the way to "higher" practice. The *Kośa* does not rank these by moral value; it ranks them by *altitude of goal*. 順福 is the conforming toward worldly happiness, and worldly happiness is a real and legitimate ripening.
Thursday, 11:00 p.m., in bed
M. has been trying, for several months, to sit for ten minutes before sleep. Tonight she sits. The mind is loud — three work threads, a small argument replay, a desire to check something on the phone. She watches.
By the 定之順逆 framework, this is the most literal 順逆 of the day. Each minute of sitting is either 順趣上界 (*shùn qù shàng jiè*, conforming upward — the mind gathering, the body quieting, the mental factors thinning in a particular way) or 逆墮下界 (*nì duò xià jiè*, opposing/falling downward — the mind scattering, the body tightening, the threads re-knitting).
Note the classical nuance: 順 vs. 逆 here is *not* "pleasant vs. unpleasant." The first ten minutes of sitting can feel unpleasant but be 順 (the discomfort is the early stage of conforming upward, a sign the body-mind is being asked to gather); and a sitting can feel pleasant but be 逆 (a kind of dull, pleasant drifting that does not lean anywhere at all — what the texts call a "leaning" with no altitude).
What M. does, when she watches the threads without following them, is essentially choosing the 間 (*jiàn*, intermediate, gradual) mode — passing through each mental distraction as a stage, not leaping past them. The 順/逆 question in her sit is not "Did I have a good meditation?" but "Did this minute lean toward *somewhere*?" The watcher-function itself is a small piece of 順趣上界, even if only by a degree.
Friday, a difficult conversation with her partner
The conversation is about money — specifically, an unannounced small purchase. The partner is hurt and a little sharp. M. feels the old heat rise: defensiveness, the urge to *win* the argument rather than repair it.
Each sentence she speaks is, in real time, either 順 with the existing heat (and so conforms with more of the same — *感*, *引*, *生*: feel, draw forth, give rise to) or 逆 with the heat (and so works *against* it — *背*, *違*: turn one's back on, violate the trajectory). She knows, from past experience, that "I hear you" spoken from genuine attention is 順 with repair — it conforms with the vipāka of the next ten minutes. "You're overreacting" is 逆 with repair — it conforms with the vipāka of the next two hours.
The most interesting case is the silent moment, when she says nothing and just sits with the partner's pain. By the 五種差別 of 順受, that silence is acting on at least three axes simultaneously: 所緣差別 (the object has shifted from "my defense" to "their hurt"); 相應差別 (the cohort of mental factors is changing — softening, widening, lowering); 自性差別 (*zìxìng chābié*, "differentiation by own-nature") — the basic felt-tone of the moment is becoming *neutral-to-pleasant* where a moment earlier it was *painful-and-tight*.
The classic mistake: people often think 順 and 逆 are about *what you say*. The framework is more precise — it is about the direction of fit between action and its ripened feeling-tone. Silence, breath, attention, a single word — all of these act on the trajectory.
Sunday, looking back
By Sunday, M. has logged something like 300+ small conformings and opposings. Almost none of them felt, in the moment, like a "spiritual" choice. Almost all of them shaped what the next moment, the next hour, the next conversation felt like. This is what the *Kośa* means when it says 順 walks with 感、引、生 — the verb family of *ripen, draw forth, give rise to*. It is a verb family that operates below the threshold of deliberate choice.
三、當代人為什麼需要它
Several features of contemporary life make the 順/逆 framework particularly worth carrying — *not* as a religious overlay, but as a clear lens.
1. The contemporary self is being acted on by conformings it did not choose.
The largest single source of vipāka-shaped feeling in a contemporary person's day is *not* what they did. It is what was done to them — by algorithmic feeds, attention-engineered interfaces, work cultures, family patterns, social comparison loops. Each of these is engineered precisely to *conform with* (順) a particular felt state in the user: engagement, anxiety, belonging, inadequacy, optimism, exhaustion. Modern product design is, in a striking sense, a massive industrial-scale 業與受之順 machine — except it operates on the *receptor* side and then back-shapes the *actor* side.
The framework's contribution is not moral alarm — it is *vocabulary*. When you can name that a stream of inputs is "conforming with a particular feeling-state in you," you can ask the next question: "Conforming with *which* of the three 順?" Conforming with 順福 (desire-relm wholesome action — like a real friendship, a walk, a good meal)? Conforming with 順解脫 (a leaning toward less reactivity)? Or conforming with 順決擇分 (a leaning toward the seeing of how things actually are)? If the answer is "none of these; it conforms with engagement-for-its-own-sake," the *Kośa* would simply call this 順 with something else — and the cost is that the ripening is not the ripening you would have chosen.
2. The "direction" of action has become invisible.
In a slower, more embodied life, the *direction* of an action was often legible: you plant, you tend, you harvest; you build, you use, you repair. In a contemporary life of fragmentary tasks and abstract labor, the *trajectory* of an action is hidden — you cannot always see what your work is "conforming with," because the ripening is delayed, distributed, and often impersonal.
The 順/逆 pair restores the question of *direction* itself: not "Is this good or bad?" but "What is this *leaning toward*?" This is a question contemporary psychology has been circling around — in research on procrastination (which is, technically, an action that 順 with short-term relief and 違逆 with the long-term project, and so the vipāka is the felt-state of being behind); in research on habit formation (where the small action, repeated, *conforms with* a stable neural pathway); in research on mindfulness, which is essentially a practice of *noticing the direction of conforming while it is still happening.*
I should be careful here: neuroscience has demonstrated use-dependent plasticity — neural pathways strengthen with repetition — and predictive-coding models of how the brain settles into particular expectation loops. These give a *physical substrate* that is loosely analogous to 順, but they do not establish karmic causation in the classical Buddhist sense. The brain is a *medium* in which directionality can be observed; whether *mind itself* carries the trajectory across time is a question the classical framework answers and contemporary neuroscience does not. The analogy illuminates; it does not prove.
3. The 順福 / 順解脫 / 順決擇分 hierarchy gives a usable map.
Most people's ordinary moral reasoning has only two altitudes: "is this OK or not OK?" The *Kośa* offers three. This is useful because:
- You can be doing 順福 well and still feel an ache that 順福 alone will not address — because 順福 produces desire-realm happiness, and desire-realm happiness is, by definition, the kind that *ends*. Recognizing this ache is not ingratitude; it is the beginning of asking about 順解脫. - You can be doing 順解脫 and find that your practice has become comfortable, almost decorative — a way of feeling spiritual without the sharpness of insight. That is the moment the *Kośa* would point you toward 順決擇分: the four path-preparations — heat, summit, patience, supreme — which are *conforming with the actual seeing of how things are*, not with the comfort of practice.
For a contemporary practitioner, this three-level map prevents two common failures: spiritual bypassing (using 順解脫 vocabulary to avoid ordinary 順福 goodness — relationships, work, the basic kindness of being human); and worldly flatness (doing 順福 well but treating it as the whole of life, missing the question of liberation).
4. Even without a metaphysical commitment, the framework trains a useful attention.
You do not have to believe in karma-as-ontology to use 順/逆 as an *attentional discipline*. The discipline is: "At each moment, ask — *what is this action conforming with?* And *what is this feeling the ripening of?*" Practiced honestly, this produces a remarkable clarity about one's own life. Many people who practice something like this — under the names of mindfulness, of *examen*, of journaling, of "checking the direction" — are essentially rediscovering the *Kośa*'s grammar.
四、常見誤讀與澄清
誤讀一：「順就是好，逆就是壞。」
This is the most common collapse, and the *Kośa* itself dismantles it. **順 is *directional fit*, not *moral goodness*.** The same word 順 describes both wholesome action's fit with its pleasant vipāka and unwholesome action's fit with its painful one. The *Kośa* verse begins: "順樂苦 — *conforming with pleasant [and] painful*" — putting wholesome and unwholesome under the same verb. What changes is not 順/逆 but the *object* of the conforming.
Concretely: a long-practiced habit of resentment is 順 with resentment's ripening — it conforms with a particular felt-state — even though the action is unwholesome. A meditation practice can be 順 with deeper samādhi, or it can be 順 with a quiet, pleasant, drifting state that conforms with *no altitude at all*. The word does the work; the moral evaluation is supplied by what is being conformed *with*.
The reverse is also true: 逆 can be virtuous. In Mahāyāna imagery, the bodhisattva who "goes against the current" (*pratisaṃyukta*, sometimes rendered 逆流) of saṃsāra is doing something 逆 with ordinary worldly comfort and 順 with nirvāṇa. The Great Vehicle even names "five acts going against [the parents, the Buddha, the Saṅgha, the teaching, the community]" — 五逆罪 (*wǔ nì zuì*) — where 逆 is not "wrong" but "the most serious breach in the direction of the path." 逆 and 順 are *directional* terms; goodness and badness are layered on top.
誤讀二：「順逆 = 善惡 (good vs. evil).」
Slightly more sophisticated, but still a collapse. **善 (*shàn*, wholesome) and 惡 (*è*, unwholesome)** are moral categories that *often* line up with 順/逆 — wholesome action tends to 順 with pleasant vipāka; unwholesome tends to 順 with painful vipāka — but the categories are not identical. The *Kośa*'s three 順 (順福, 順解脫, 順決擇分) are *all* wholesome, yet they are not the same altitude of goal. And unwholesome action can 順 with itself (the resentment that conforms with more resentment) without that being "good" in any sense.
A clear contemporary example: a high-performing workaholic is doing actions that 順 with their felt-state of high-performing workaholic (clarity, drive, slight anxiety). Those actions are not unwholesome in a moral sense — they may even be skilled — but they are 順 with a particular *altitude*, and the ripening they conform with is the ripening the workaholic is already in. The framework's question is not "Are you good or bad?" but "What altitude are you conforming toward?"
誤讀三：「順逆是關於『結果』——所以要看長期結果才知道順還是逆。」
This sounds plausible, but the *Kośa* is more radical. 順/逆 is observable in the action itself, by its relational structure, not only by its eventual vipāka. The five-fold analysis of 順受 — by its own-nature, by associated factors, by object, by ripened result, by manifest arising — shows that the *fit* can be read at *every* level, including right now. A moment of anger is 順 with itself in the *相應差別* (the associated factors — tightening, heat, narrowing — are already there); you do not need to wait for the long-term consequence to recognize the conforming.
This matters for practice. If 順/逆 were only readable in long-term outcomes, we could not orient ourselves in real time. But the framework says: each action carries its direction in its own structure, and that direction is available to a清醒的 (sober, clear) attention.
誤讀四：「順就是『跟著感覺走』，逆就是『對抗感覺』。」
Modern culture often translates spiritual frameworks into "follow your heart / override your heart," and the result is poor. **順 in the *Kośa* is not "following feeling"; it is *the directional fit between action and its ripening.*** A wholesome action may require *going against* the immediate feeling (saying the hard true thing; sitting through discomfort in meditation; staying present with a partner's pain when the urge is to flee). Such an action can be 順 with a higher altitude (the ripening of integrity, of samādhi, of repair) precisely *because* it is 違逆 (*wéinì*, opposing) with the immediate felt-state.
Conversely, 逆 is not the same as discipline. A forced discipline that crushes the person and produces bitterness is often 順 with a different felt-state (the small satisfaction of self-punishment) and not genuinely 順 with the deeper ripening the discipline was nominally for. The framework is more subtle than "feel bad now, good later" or "feel good now, bad later." It is about the relational fit between what you do and what you are becoming, at every level.
誤讀五：「順逆是靜態的標籤 — 順了就順了，逆了就逆了。」
The *Kośa*'s treatment of 定之順逆 explicitly contradicts this. In meditative attainment, the same concentration can be 順趣上界 (conforming upward) at one moment and 逆墮下界 (opposing and falling downward) at the next, as the meditator passes through intermediate stages, sometimes gradually (間), sometimes by leaping (超). Direction is *not* a static attribute; it is the *trajectory* of the moment.
For non-meditators, this is also true: a conversation can start 順 with repair and become 逆 with repair in the same sentence; a meditation sit can start 順趣上界 and, fifteen minutes in, become 逆墮下界 without the meditator noticing. The framework asks not "Which one is this?" but "**Where is this leaning, *right now*?**"
誤讀六：「這是阿毘達磨的專門術語，跟一般人無關。」
This is a lazy misreading that protects the *Kośa* at the cost of its usefulness. The grammar is technical, but the logic is everywhere. Every parent who notices that one response to a child's emotion *fits* with calm and another *fits* with escalation is using the logic. Every person who notices that one friendship is *going somewhere* and another is *going nowhere* is using the logic. Every meditator who notices that today's sit leaned toward clarity and yesterday's sit did not is using the logic. The technical names help — they make the implicit explicit, the scattered systematic — but the *Kośa* is not introducing a strange metaphysics; it is giving rigorous names to something human beings have always half-seen.
A Closing Image
The *Kośa*'s image for 順 is implicit in its verb family — 感, 引, 生 — and for 逆 in its verb family — 背, 違, 墮. Picture a river. 順 is the current that the river has; it carries whatever is in the water toward the river's mouth. 逆 is the current *against* the river's natural lean — and here is the precision: a small eddy behind a stone is 逆 with the main current, but it is not nothing; it is its own small system with its own small conformings. Every eddy, every tributary, every drop has a direction.
The question the *Kośa* is asking, through this pair of characters, is the question every human being eventually faces with some seriousness: At this moment, in this action, in this habit, in this relationship, in this practice — what am I conforming with? And what is that conforming carrying me toward?
You do not need to be a Buddhist to ask this. You only need to be honest about direction.
