What This Concept Is About
When contemporary readers hear "禪" (Chan/Zen), many picture a Zen monastery, a roshi, or the taste of "no-mind." The classical term 禪支 (dhyānāṅga, literally "absorption-factors" or "jhāna-constituents") points to something far more technical and far more useful: it is a precise map of *what mental qualities must be present* for the mind to settle into each of the four meditative absorptions (dhyāna, 靜慮). The image at the center is not a monastery but a still lake, and 禪支 is the catalogue of the conditions — the temperature, the stillness of wind, the clarity of water — that allow the lake to form.
The classical source we are drawing on — the *Abhidharmakośa* (《阿毘達磨俱舍論》, T1558) — opens with a clear inventory. The first dhyāna has five factors (五支): *vitarka* (尋, initial application of thought), *vicāra* (伺, sustained examination), *pīti* (喜, joy/interest), *sukha* (樂, ease), and *samādhi* (等持, one-pointed settling). The second dhyāna has four factors (四支): inner purity or clarity (內等淨), *pīti*, *sukha*, and *samādhi*. The third dhyāna has five factors: equanimity of engagement (行捨), right mindfulness (正念), right wisdom/intelligibility (正慧), *sukha*, and *samādhi*. The fourth dhyāna has four factors: purified equanimity (行捨清淨), purified mindfulness (念清淨), neither-painful-nor-pleasant feeling (非苦樂受, *upekkhā-vedanā*), and *samādhi*. The total count is eighteen names across the four dhyānas.
Before going further, three technical clarifications are essential. Without them the whole map is misread.
First, the dhyāna is not identical with its factors. The text states this with surgical precision: "唯等持是靜慮亦是靜慮支, 餘十七名是靜慮支非靜慮" — *only samādhi is both the dhyāna and a factor of the dhyāna; the other seventeen are factors but not themselves the dhyāna*. The analogy given is the "four-division army" (四支軍): the army as an organized force is one thing; its divisions (infantry, cavalry, chariots, command) are another. The army is not the infantry; the infantry is not the army. Likewise, *the dhyāna as a unified state of absorption is samādhi; the factors are the qualities that constitute and accompany that state*. This distinction prevents the common confusion of mistaking a "quality of the state" for "the state itself." When you feel joy in deep meditation, the joy is not the dhyāna — it is a factor *in* the dhyāna.
Second, "等持," "定," and "心一境性" are three names for the same thing. The text explicitly states "等持與定名異體同, 此亦名為心一境性" — *samādhi, samādhi, and cittaikāgratā are different names, one referent*. So when you see *samādhi*, *定*, *三摩地*, or *心一境性* in different translations, they all point to the same mental factor: the mind's capacity to remain one-pointedly on its object. The label changes; the function does not.
Third, the eighteen names reduce to eleven distinct dharmas. Several factors recur across dhyānas: *pīti*, *sukha*, and *samādhi* appear in the first three dhyānas; *saṃskāra-saṃskṛta-upekṣā* (行捨) and *samādhi* appear in the third and fourth. Removing duplication, the four dhyānas together involve only eleven actual mental factors. The text uses the formula "有是初支非第二支" ("there is that which is a factor of the first dhyāna but not the second") to map which factors are unique to which dhyānas. This matters because the eighteen names might suggest eighteen distinct phenomena, when in fact the practice is about cultivating and recognizing a smaller, stable set of mental qualities in different configurations.
Now the subtle point that most contemporary readers find genuinely surprising. The *sukha* (樂, "pleasure/ease") listed as a factor in the first and second dhyānas is not the pleasure we normally mean. The text argues this carefully: in deep samādhi, the five-sense consciousnesses (眼耳鼻舌身識) are suspended, so there can be no bodily feeling of pleasure (身受樂). Moreover, *pīti* (joy) is itself a pleasant feeling (喜受), and the Abhidharma holds that two feelings cannot co-occur in one mind at one time (一心中二受不俱行). Therefore the "sukha" in the first two dhyānas cannot be either bodily pleasure or mental pleasure. What is it, then? The text identifies it as *praśrabdhi* (輕安) — physical and mental pliancy, release of tension, supple ease. *Real* bodily sukha, the *sukha-vedanā* rooted in the body (樂根), does not appear until the third dhyāna. The supporting scripture quoted is precise: in describing the "joy arising from seclusion, with bodily attestation" (離生喜身作證具足住), the factors are listed as five: *pramod* (歡), *pīti* (喜), *praśrabdhi* (輕安), *sukha* (樂), *samādhi* (三摩地) — "歡喜" then "輕安" then "樂" then "三摩地", each named distinctly so that lightness and pleasure are not conflated. The practical implication is enormous and rarely appreciated by modern practitioners: the "feel-good" of early deep sitting is mostly *the falling away of tension*, not the arrival of pleasure. It is a relief-map, not a pleasure-map. Genuine somatic bliss is a later, more refined attainment.
This is the architectural meaning of 禪支: it is a progressive map of what the mind looks like as it settles, in which each successive dhyāna *subtracts* certain coarser qualities and *adds* or refines subtler ones, with *samādhi* as the constant backbone throughout.
Walking Through This in Contemporary Life
The most direct contemporary context is, of course, the meditation cushion — millions of people now sit regularly, even if briefly. Let us trace a typical hour of practice against the 禪支 map, the way the *Kośa* itself would have us trace it.
You sit down. The breath is your object. For the first several minutes, your mind is busy: it reaches toward the breath, examines it, drifts to a thought, returns, comments, evaluates. This discursive, reaching-and-examining activity has two movements: the initial *applying* of thought to the object (尋, vitakka) and the *sustained examination* (伺, vicāra). When these are present and accompanied by a one-pointed settling on the breath, you are at the threshold of the first dhyāna. The factors present: 尋, 伺, 喜, 樂, 等持. Many meditators never realize this — they think they have "failed" because their mind is still active. But the *Kośa*'s map says: discursive activity with one-pointed settling *is* the first dhyāna; it is not a failure to reach it.
Now look for the *pīti* (喜). In contemporary language, *pīti* is not the joy of laughing with a friend; it is the felt sense of *interest*, *liftedness*, *zest*, an energy-arousal in the body. It might feel like pleasant tingling in the chest or scalp, or a childlike freshness in the mind. When it arises along with the first two factors, the first dhyāna is *complete*. Then the "sukha" — but remember, here this means *praśrabdhi* (輕安), pliancy: shoulders drop, jaw releases, the abdomen softens, attention feels frictionless. It is easy to mistake this for "I am relaxed, therefore I am in pleasure." The *Kośa* insists you do not yet have *sukha-vedanā*; you have only the *absence of strain*. Useful to know, because modern practitioners often chase this state as if it were pleasure, then feel they have "lost something" when they pass through it.
Suppose you continue sitting. The breath becomes subtler. The discursive activity of 尋 and 伺 — the inner commentary, the "now I am watching the breath, this is the in-breath, this is the out-breath" — drops away. This is not a failure of attention; it is the entry to the second dhyāna. What replaces 尋 and 伺 is 內等淨, *inner clarity* or *inner purity* — a self-evident knowing that does not need verbal commentary. The mind knows the breath *without thinking about the breath*. Pīti is still there (interest/liftedness), and so is praśrabdhi-as-sukha (ease). And samādhi is stronger. The factors: 內淨, 喜, 樂, 等持. Many vipassanā and Zen practitioners describe this as "just sitting" or "shikantaza"; the *Kośa* would call it the second dhyāna. The two traditions emphasize different facets but are tracking overlapping territory.
Continue deeper. Even the *pīti* — the liftedness, the energy-arousal — drops away. This is a critical transition. What was exciting is no longer exciting, but you do not feel dulled. The mind has become very even. Here the *Kośa*'s third dhyāna arrives. The new factors are *upekṣā with saṃskāra* (行捨, equanimity of engagement — meaning the mind continues to function but without the urgency of either pursuit or avoidance), *right mindfulness* (正念), and *right intelligibility* (正慧). And now, for the first time, the factor called 樂 is actually *sukha-vedanā* rooted in the body — a full, warm, pervasive bodily ease. Many meditators, especially those practicing body-scan or noting traditions, will recognize this state as "the body is glowing" or "I am soaked in ease." It is not the relief-of-tension you felt in the first dhyāna; it is positive bodily pleasure. The factors: 行捨, 正念, 正慧, 樂, 等持. This is the classical "離喜妙樂" — the *wondrous bliss that has set joy aside*.
Finally, suppose you go further. Even the *sukha* is seen as a subtle stirring. It drops away. What remains? Refined equanimity — purified of any sense of *doing* (行捨清淨), purified mindfulness (念清淨), a feeling that is neither pleasant nor unpleasant but simply *neutral and clear* (非苦樂受), and samādhi. The factors: 行捨清淨, 念清淨, 非苦樂受, 等持. Many readers will recognize this as "equanimity" in modern vipassana language, or "无所住" in the *Diamond Sutra*'s phrasing. The *Kośa* calls it the fourth dhyāna. It is not blankness — it has the four refined factors — but the coarseness of all excitement, all ease, all displeasure has been let go.
This is the cushion walk-through. But the *Kośa*'s map also illuminates experiences far from the cushion. Consider learning a difficult skill — say, learning a language as an adult, or a piece of music on an instrument. The first dhyāna's structure maps easily: in the early phase, you reach (尋) and examine (伺) constantly — translating, conjugating, comparing, fixing fingering. There is excitement (pīti) at each breakthrough. There is a relief-of-tension (輕安) when a concept finally clicks. And there is *samādhi* — moments when the mind is one-pointed on the task without you forcing it. Eventually, with practice, the verbal commentary drops: you no longer translate internally, no longer think about fingering. You simply know. That is the *inner clarity* (內淨) of the second dhyāna. Eventually, even the excitement drops: you no longer get a thrill at each success. You work steadily (行捨), with clear mindfulness (正念) and clear comprehension (正慧), and the body itself feels easy in the practice (樂 as *sukha-vedanā*). The mastery stage is the third dhyāna. Finally, in genuine mastery — a concert pianist sight-reading, a fluent speaker mid-conversation — there is no pleasure, no displeasure, just equanimity, refined mindfulness, and one-pointed function. The fourth dhyāna.
The same map fits creative flow (writing, coding, painting), athletic flow (the runner's "second wind," the swimmer who has settled), and — less obviously but importantly — a hard conversation with someone you love, where you start by arguing with yourself ("but I should say… but he will think…") — that's 尋 and 伺; the moment of breakthrough to actually *listening* without inner commentary is 內淨; the warmth that arises when you understand their pain without defending is *sukha-vedanā*; the mature response that needs no internal cheerleading is the fourth dhyāna's refined equanimity.
The map is not "this state is good, that state is bad." The *Kośa* is precise: each dhyāna is its own complete configuration of factors, valid in its own context. The point of the map is *recognition* — to know where you are, what is present, what has dropped, what can be developed.
Why Contemporary People Need This Map
Modern meditation culture has produced a paradox: more people sit than ever before, but the conceptual vocabulary for *what is happening during sitting* has thinned. Beginners are told to "watch the breath" or "be present." Apps provide timers and bells. Teachers offer gentle reminders. But when something genuinely unusual happens — a rush of energy at the chest, a sudden deep calm, an experience of seeming effortlessness, an unsettling neutrality — most practitioners have no framework. They either chase the pleasant states ("I want to feel that lightness again"), dismiss them as imagination, or get worried ("did I fall asleep?").
The 禪支 map offers something a generation of meditators actually lacks: a *non-moralizing, descriptive vocabulary* for the stages of deepening. It does not tell you the fourth dhyāna is better than the first. It tells you the first dhyāna has *vitarka* and *vicāra* present, while the second does not — that is a *factual* observation about your present state. With this vocabulary you can orient yourself in meditation without resorting to either spiritual consumerism ("I had a great sit!") or to self-doubt ("I didn't feel anything special, so I failed").
There is a second, less obvious need. Modern attention research — to take one strand of contemporary science, with its own well-known limitations and unresolved questions — describes "flow states," default-mode-network quietening, focused-attention training, and the like. The vocabulary overlaps with the 禪支 map in suggestive ways: the dropping of inner commentary (vicāra) maps onto the quieting of the default mode network; the sustained one-pointing maps onto focused-attention training. But the *Kośa*'s map goes further than contemporary neuroscience currently has precise instruments for: it tracks *qualitative shifts in the felt sense of pleasure* (from praśrabdhi in early dhyānas to sukha-vedanā in the third), and it tracks the *subtraction of coarser qualities* (the systematic letting-go of vitakka, vicāra, pīti, sukha). Modern research can confirm some correlates but has not (so far as can be said carefully) given a complete account of these qualitative transitions. The classical map is therefore not redundant with what contemporary science offers; it covers experiential territory that the science is still catching up to.
A third, more existential need: in a culture saturated with stimulation, the *capacity to recognize that pleasure is not always what one thinks it is* is genuinely useful. The *Kośa*'s distinction between praśrabdhi and sukha-vedanā is, in contemporary terms, a teaching on the difference between *relief from tension* and *positive embodied well-being*. Many people today oscillate between states of tension and states of relief, and mistake the latter for pleasure. The classical map names this distinction precisely. It also names the next stage — a *positive* bodily ease that does not depend on the absence of the previous state — which contemporary vocabulary often conflates with simple relaxation.
Common Misreadings and Clarifications
1. "禪支 = parts of Zen Buddhism." No. 禪 in this technical sense is *dhyāna* — a specific set of meditative absorptions described across Buddhist traditions, including Theravāda, Sarvāstivāda, and others. It is not a school. The Chan/Zen tradition of East Asia inherits the word but is a distinct historical movement. In the *Kośa* and in Abhidharma generally, 禪 refers to a graded series of absorptive states, not to a school of practice.
**2. "The factors *are* the dhyāna."** No — only *samādhi* is both the dhyāna and a factor. The other seventeen are factors but not the dhyāna itself. The *Kośa*'s "four-division army" analogy is exactly meant to prevent this: the army is not its infantry, and the infantry is not the army. This matters practically because if you mistake, say, *pīti* for "the dhyāna," you will chase the high of *pīti* and miss the more refined stages that drop it.
3. "The 'pleasure' of the first dhyāna is genuine pleasure." As discussed above — this is the most common modern misreading, and the *Kośa* addresses it head-on. The "樂" in the first and second dhyānas is *praśrabdhi* (輕安, pliancy, release of tension), not *sukha-vedanā*. Real sukha-vedanā arises in the third dhyāna. The text quotes a scripture enumerating five distinct qualities — *pramod* (歡), *pīti* (喜), *praśrabdhi* (輕安), *sukha* (樂), *samādhi* (三摩地) — precisely to prevent their conflation. Contemporary meditators frequently mislabel the relief-of-tension state as "deep pleasure," which sets up an unhelpful chase for early-dhyāna sensations that are actually quite modest.
4. "There are eight factors total." No — there are *eighteen names* across the four dhyānas, but only *eleven distinct dharmas* in fact. The *Kośa* spends a section on this counting because the nominal count can mislead.
5. "禪支 = 齋支." Both contain the character 支, but they are entirely different things. 齋支 (factors of the uposatha observance, the eight-precept day) refers to aspects of *sīla*, ethical and disciplinary practice — factors like 尸羅支 (precept factor), 不放逸支 (vigilance factor), 禁約支 (restraint factor). 禪支 refers to factors of *samādhi*, the absorptive mind. The two share a word but belong to different divisions of the path (morality and concentration, respectively).
6. "Each dhyāna is 'better' than the one before." The *Kośa* is careful: each dhyāna is a complete configuration of its own factors, valid in its own context. The progression from first to fourth is not moral but *subtractive* — coarser qualities (verbal activity, then excitement, then pleasure itself) are systematically let go, revealing subtler ones. None is discarded as wrong; each is recognized and, where appropriate, passed through.
7. "Samādhi, 定, 三摩地, 心一境性 are different things." No — the *Kośa* explicitly equates them: "等持與定名異體同, 此亦名為心一境性" — three names, one referent. Different texts translate the same Sanskrit/Pali term *samādhi* in different ways, but the referent is stable. (Note: 禪那 and 三摩地 are sometimes distinguished as *dhyāna* versus *samādhi* in some contexts, but in the *Kośa*'s own analysis here, 靜慮 is defined by reference to 等持, and the three-way equivalence is stated explicitly.)
8. "If my mind is silent, I must be in the fourth dhyāna." The map is more granular than that. Silence of inner commentary by itself indicates the *absence* of vitakka and vicāra — that is the transition from first to second dhyāna. The fourth dhyāna additionally has *pīti* and *sukha* also dropped. Genuine fourth-dhyāna equanimity is not just "no thought"; it is refined equanimity, refined mindfulness, and a neutral, clear feeling-tone, all on the bedrock of one-pointed settling. Many contemporary descriptions of "no-mind" describe a state closer to second dhyāna's 內淨 than to fourth dhyāna's full configuration.
Closing Reflection
禪支 is, in the end, a very practical teaching dressed in a very technical vocabulary. It tells the practitioner: as your mind settles, certain qualities arise together, and certain qualities fall away together. You do not need to climb an Everest of attainment; you need to recognize, with precision, what is here in this moment of sitting, this moment of work, this moment of conversation. The four-division army image is the one to carry forward: an army does not become an army by being infantry alone, nor cavalry alone. It becomes an army when the divisions are organized around a unified command and function together. 禪支 is the catalogue of those divisions; *samādhi* is the organizing principle that makes the dhyāna itself. Knowing the difference is, paradoxically, the beginning of seeing them work together.
