行

What This Concept Is Saying

The Chinese word 行 (*saṃskāra*, “formations,” “constructive activities,” or “conditioned processes”) is deceptively simple. In ordinary Chinese, it can mean acting, practicing, proceeding, or conduct. In Buddhist texts, however, its meaning changes with context. Its central sense is 造作遷流: conditioning and constructing, while continually passing from one state into another.

This has two inseparable aspects:

- 造作, constructive activity: conditions combine to shape an experience, disposition, deed, or future result. - 遷流, ongoing transition: what has been constructed does not remain fixed; it changes, transmits effects, and conditions what follows.

Thus 行 is neither merely “external action” nor simply “movement.” A thought can be 行; an intention can be 行; a habit reinforced without visible movement can be 行. In the broad expression 諸行 (*sarva-saṃskāra*, “all conditioned formations”), even physical and mental phenomena produced through conditions may be called 行.

To understand the term accurately, we must distinguish at least four major uses.

1. 行 as the 行陰／行蘊 (*saṃskāra-skandha*, formation aggregate) within the five aggregates 2. 行 as the second link of dependent arising, conditioned by ignorance 3. 諸行 as conditioned phenomena generally 4. 行 as spiritual practice or cultivation

These senses overlap, but they are not interchangeable.

1. 行 within the five aggregates

When Buddhist texts list 色, 受, 想, 行, 識—form, feeling, perception, formations, and consciousness—行 refers to the formation aggregate. Some early Chinese translations call these 五陰 or 五受陰 rather than 五蘊; the underlying analytical function is similar, but the source’s terminology should not be silently replaced.

Here 行 is not “what a person physically does.” Nor is it a miscellaneous box for everything that cannot be classified elsewhere. Its center is volitional and formative mental activity: the tendencies, intentions, impulses, orientations, and conditioning factors that make the mind incline, organize itself, and produce further consequences.

The *Saṃyukta Āgama* gives a concrete definition:

“What is it to know 行 as it really is? It is the six bodies of volition: volition born of eye-contact, and volition born of ear-, nose-, tongue-, body-, and mind-contact. This is called 行.” —《雜阿含經》

The expression 六思身 means six classes of 思 (*cetanā*, volition or intention) arising in dependence upon contact through the six sense domains. The *Mahāratnakūṭa Sūtra* gives a corresponding sixfold presentation: volition concerning forms, sounds, smells, tastes, tangibles, and mental objects.

Suppose you see an insulting message. Seeing and recognizing the words are not yet the whole of 行. The mind’s movement toward replying, suppressing, rehearsing, retaliating, explaining, forgiving, or withdrawing belongs centrally to the field of formation. It is the mind being disposed in a direction and helping construct what comes next.

This includes both unwholesome and wholesome formations. Resentment, possessiveness, and deception are formative; so are generosity, restraint, patience, careful attention, and the intention to understand. As the *Ekottarika Āgama* puts it, 行 is so called because it can bring something about: it may accomplish unwholesome conduct or wholesome conduct.

The formation aggregate therefore must not be reduced to “karma” in every occurrence. It is broader than karmically decisive intention alone. Some scholastic systems place within it numerous mental factors capable of conditioning the mind, including both defiled and purified factors. Its organizing center remains constructive or dispositional activity.

The classical image for this aggregate is exact and important: 行 is like a banana trunk. A banana plant appears to have a solid core, but when its layers are peeled away, no independent hardwood center is found. Likewise, we may say, “This is just who I am—I am an angry person, an anxious person, a disciplined person.” Yet close examination reveals habits, reactions, intentions, memories, bodily conditions, social training, and repeated choices layered together. There is conditioning and causal efficacy, but no unchanging owner hidden at the center.

The analogy does not say that formations do not function. A banana plant still stands and grows; habits still bear consequences. It says that their functioning does not require an indivisible, self-existing essence.

Within the five aggregates, 行 is contemplated alongside the other four as impermanent, stressful when grasped, subject to change, and not-self. The point is not to despise mental formation. It is to stop treating a conditioned pattern as “I,” “mine,” or “what I must always be.” When attachment loosens, formation can be seen, trained, and eventually released.

2. 行 in dependent arising

In the twelve links of dependent arising, 行 has a narrower and more causal meaning:

無明緣行，行緣識 — with ignorance as condition, formations arise; with formations as condition, consciousness arises.

Here 行 is 業行, karmically formative activity driven by ignorance. The Āgamas commonly analyze it as:

- 身行: bodily formation or bodily karma - 口行／語行: verbal formation or verbal karma - 意行: mental formation or mental karma

These are not merely three channels through which an already completed “self” expresses itself. They are ways in which ignorance-conditioned intention constructs the trajectory of experience and continued becoming.

The *Abhidharmakośabhāṣya* states that the links of 行 and 有 have karma as their nature. It further distinguishes:

- 福行: meritorious formations tending toward pleasant results - 非福行: demeritorious formations tending toward painful results - 不動行: “imperturbable” formations associated with refined meditative attainments and their corresponding modes of existence

This classification prevents a common simplification: ignorance does not produce only obviously immoral acts. One may perform socially admirable or spiritually refined deeds while still construing them through attachment to self, reward, identity, existence, or permanence. Such conduct may be ethically beneficial and yield favorable results, yet still remain within conditioned becoming.

That does not make goodness pointless. Wholesome formation is indispensable to the path. It means that liberation requires more than improving the contents of becoming; wisdom must also penetrate the ignorance that keeps the entire constructive cycle turning.

The link 行 is positioned between ignorance and consciousness because it transmits direction. Ignorance does not simply sit in the mind as missing information. It becomes operative through dispositions and deeds. These formations then condition consciousness and the subsequent unfolding of name-and-form, the sense fields, contact, feeling, craving, grasping, becoming, birth, and the suffering associated with aging and death.

This should not be imagined as a row of twelve dominoes falling only once. Dependent arising can illuminate long karmic continuity, but its structure is also visible in immediate experience. Not seeing clearly, we form an intention; that intention biases what we attend to; biased attention helps construct a world in which craving and grasping seem reasonable; grasping then reinforces the very identity from which the cycle began.

The texts also state the reverse movement:

When ignorance ceases, formations cease; when formations cease, consciousness ceases, and so on, culminating in the cessation of the whole mass of suffering.

“Formations cease” does not mean that an awakened person becomes inert, cannot speak, or has no ability to choose. It means the cessation of ignorance-driven karmic construction that projects and appropriates continued becoming. Compassionate activity remains possible; compulsive construction rooted in delusion does not.

The *Yogācārabhūmi* adds an important qualification: not every bodily, verbal, or mental formation is conditioned by ignorance. Undefiled activity is still activity, but it is not necessarily an ignorance-conditioned link producing further bondage. Thus “all action must stop” is not an accurate account of liberation.

3. 諸行 as all conditioned formations

In expressions such as 諸行無常—“all conditioned formations are impermanent”—行 is broader still. It refers to phenomena that arise through conditions and therefore undergo alteration and cessation.

Here the term may include far more than volition. A body, institution, relationship, mood, ecosystem, device, social identity, or meditative state can be understood as conditioned: each exists through supporting causes and changes when those supports change.

The *Mūlamadhyamakakārikā* tradition explains the emptiness of formations through their conditioned, unstable, and non-self-existing character. Because formations arise dependently, no fixed nature can be isolated that produces itself, owns itself, and remains identical through change.

Emptiness does not cancel conditionality. It explains how conditionality is possible. If anger possessed an immutable essence, it could never arise, intensify, fade, or be transformed. Precisely because it lacks fixed self-nature, it depends on conditions—and because it depends on conditions, the path can alter those conditions.

This is why 一切諸行空, “all formations are empty,” is not nihilism. It does not say that nothing appears or that consequences are imaginary. It says that appearances and consequences occur without an autonomous core.

The *Buddha’s Explanation of the Profound Secrets Sūtra* discusses the relation between 諸行 and 真如 (*tathatā*, suchness or reality as it is) as 過一異相: beyond the rigid alternatives of identity and difference. Suchness is not simply identical with the confused appearances grasped by ordinary cognition; otherwise everyone who perceived formations would already realize suchness. But suchness is not a second, separate substance standing outside conditioned phenomena; otherwise insight into it could never release attachment to the characteristics of formations.

The practical point is subtle. Liberation does not require finding a metaphysical realm behind daily life. It requires seeing conditioned life without imposing self-existence upon it.

4. 行 as practice

Finally, 行 can simply mean cultivation, conduct, or progress along the path. The *Mahāprajñāpāramitāśāstra* includes hearing, reciting, writing, correctly recollecting, explaining, reflecting, examining, distinguishing, and cultivating within this broad sense of practice. Other exegetical texts describe non-negligence, tranquility, insight, generosity, discipline, patience, and the remaining perfections as forms of 行.

This use should not be confused with the dependent-arising link. Meditation undertaken with right view is “practice,” but it is not thereby an ignorance-driven karmic formation in the technical twelve-link sense.

The ambiguity is instructive. The same human capacity to form patterns can bind or free. Repeated grasping constructs bondage; repeated mindfulness and wisdom cultivate the conditions in which grasping is understood and relinquished. The path uses conditioned practices to reach the end of compulsive conditioning—much as a raft is constructed and used to cross water, without being carried forever after reaching the far shore.

A Walk-Through in Everyday Life

Consider a familiar scene: late at night, after an exhausting day, you open a social-media app “for five minutes.” You see a colleague announcing a promotion.

Let us walk through the event without squeezing every moment into a rigid formula.

First, visible shapes and colors appear through eye and screen. The phone, the image, and the body holding it belong to the domain of 色—material form. In five-aggregate analysis, 色 is not merely “my body”; it includes material phenomena, inward and outward.

Eye, visible form, and eye-consciousness condition contact. A feeling tone follows: perhaps unpleasantness, tightening, or a brief mixture of attraction and pain. This is 受 (*vedanā*, feeling), not yet the full story “My life is a failure.” Feeling means the affective tone—pleasant, painful, or neither-painful-nor-pleasant—not an elaborate emotion or judgment.

Next, 想 (*saṃjñā*, perception or recognition) takes up marks: “That is my colleague”; “promotion”; “successful”; “everyone is advancing except me.” Strictly speaking, 想 is the taking and recognition of signs, not simply “having thoughts” or imagination.

Then formation becomes especially visible. The mind leans and constructs:

- an impulse to compare; - an intention to inspect the colleague’s profile; - a rehearsal of past grievances; - an urge to post something impressive; - a decision to keep scrolling; - perhaps, after mindfulness appears, an intention to put the phone down and attend honestly to the pain.

These are examples of 行 as volitional and formative activity. The app’s algorithm may supply conditions by selecting attention-grabbing material, but it does not explain the whole event. Personal history, fatigue, social values, present feeling, recognition, and intention interact. The algorithm is neither an all-powerful external fate nor merely irrelevant.

The sixfold definition is also visible. This particular formation begins with volition associated with eye-contact; another may arise from sound when a notification chimes, from bodily contact when the hand automatically reaches for the phone, or from mind-contact when yesterday’s comparison returns in memory. “Six bodies of volition” does not mean six mystical substances. It classifies intention according to the sensory or mental contact upon which it arises.

Now place this in dependent arising.

Ignorance here is not merely failing to know a fact. It may be the unexamined conviction that status will give a permanent self lasting security, that this painful feeling is “me,” or that the colleague’s post reveals an independently existing measure of human worth.

Conditioned by that not-seeing, formations arise: comparison, strategizing, self-display, hostility, or compulsive scrolling. Those formations influence the next moments of consciousness. Attention becomes tuned to evidence of inadequacy. Neutral posts are interpreted competitively. Craving emerges: “I must become someone impressive.” Grasping follows: “My career is my identity.” Becoming develops as one repeatedly inhabits the role of the overlooked, striving, resentful self.

The “future birth” produced here should not be carelessly equated with the full doctrinal meaning of rebirth. Yet, as an immediate analogy, a recognizable identity is being born from moment to moment. The analogy helps us see the mechanism locally; it neither exhausts nor replaces the traditional karmic and rebirth framework.

Suppose instead that mindfulness intervenes. You notice:

“This is painful feeling. Recognition is comparing. The mind is preparing a defensive story. An impulse is present, but it is conditioned and not-self.”

You do not need to declare the impulse nonexistent. You also need not obey it. Because the formation is like a banana trunk—layered, conditioned, without an unchangeable core—it can be met differently. Perhaps you breathe, close the app, congratulate the colleague sincerely, or reflect on your actual needs without converting them into a verdict on your worth.

That new response is also formation in the broad and aggregate senses. It may be wholesome formation cultivated by right view. It becomes part of the path because it weakens greed, aversion, and delusion rather than feeding them.

The point most often mapped incorrectly is this: the physical act of tapping the screen is not by itself “the formation aggregate,” while the inner story is not all “perception.” Tapping may express bodily karma; recognition of the post’s signs belongs to perception; its pleasant or unpleasant tone belongs to feeling; the impulses and intentions directing the next step are centrally formations; awareness of the respective objects belongs to consciousness. In lived experience these occur interdependently, not as five sealed compartments.

A second example comes from intimate relationships. Your partner says, “You never listen.” Sound is heard; painful feeling arises; perception recognizes a familiar accusation. Formation appears as the almost instantaneous preparation of a defense: gathering counterexamples, tightening posture, choosing a cutting phrase. If spoken, that mental formation becomes verbal karma and establishes new conditions in the relationship.

The liberating intervention is not emotional numbness. It is knowing the process before it fully hardens: “Pain is here; recognition has supplied an old label; retaliation is being constructed.” In that small interval, patience can be cultivated. One might answer, “I feel defensive, but I want to understand what you mean.” This too is 行—yet it is formation guided by clarity rather than ignorance.

A third example is parenting. A child refuses to leave the house. A parent experiences bodily tension and unpleasant feeling. Perception marks the behavior as “defiance.” Formation supplies the inherited script: “A good parent must control this immediately.” Speech and bodily action follow. Later, the parent says, “I became my father.” Buddhist analysis would be more precise: there was no fixed ancestral self taking possession. Conditions—memory, fatigue, fear, learned reactions, and present intention—converged into a familiar pattern. Because the pattern is conditioned rather than essential, acknowledgement, restraint, apology, and retraining are possible.

This is one of the most humane implications of 行: conditioned does not mean excused, but neither does it mean condemned to permanence.

Why Contemporary People Need It

Contemporary culture often oscillates between two pictures of the person.

The first says, “You are an autonomous individual who freely chooses everything.” This can produce pride when life goes well and crushing self-blame when it does not.

The second says, “You are entirely programmed—by genes, childhood, trauma, economics, platforms, or algorithms.” This can produce fatalism and moral passivity.

The teaching of 行 avoids both extremes. We are profoundly conditioned, yet present responses become new conditions. There is causal continuity without a permanent controller. Responsibility remains meaningful precisely because intentions have effects; transformation remains possible precisely because intentions have no fixed essence.

This is particularly useful in an algorithmic environment. Recommendation systems learn from repeated attention and then feed back material likely to reinforce it. Buddhist formation is not identical to machine learning: an algorithmic model is a technical system, while 行 belongs to a much wider ethical, experiential, and soteriological analysis. Still, the comparison is illuminating. What we repeatedly click changes what is presented next; what we repeatedly intend changes what the mind more readily intends next.

A habit is not merely an action copied many times. It is a channel through which perception, feeling, attention, and intention become more likely to flow. Each repetition makes a particular world easier to inhabit.

Contemporary neuroscience also investigates plasticity, automatic prediction, affect, and habit formation. These findings may offer useful comparative language, but they do not “prove Buddhism.” Scientific theories remain contested and methodologically limited to particular forms of observation and measurement. Buddhist analysis, meanwhile, is directed toward ethical cultivation and liberation from grasping. The two may illuminate one another in limited ways, but they should not be collapsed into equivalence.

More importantly, 行 explains why insight alone, understood as acquiring information, is insufficient. A person may know that anger is harmful and still be carried away by it. The pattern has been rehearsed in posture, speech, attention, fantasy, and reward. Liberation therefore requires practice: repeated right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration—the Noble Eightfold Path identified in the Āgamas as the path to the cessation of formations.

The Eightfold Path is itself cultivated through conditioned activities. At first, one deliberately restrains speech. Later, restraint becomes more natural. One repeatedly notices feeling without grasping it. One learns to recognize intention before it becomes action. Gradually, wholesome formations weaken unwholesome ones, and wisdom penetrates the entire process as impermanent, stressful when appropriated, empty, and not-self.

This is why the path is not self-optimization in the ordinary sense. Self-optimization asks, “How can I construct a more successful version of me?” The liberating path asks a deeper question: “How does the construction of ‘me’ occur, what suffering follows from grasping it, and what remains when the grasping is released?”

The teaching also clarifies the place of ethics. Karma is not cosmic bookkeeping imposed by an external judge. Intention forms character, attention, relationship, and future experience. Hatred does not become harmless merely because it stays inside the head; rehearsing it is itself conditioning. Likewise, an unnoticed movement of generosity may be small outwardly yet profound in the direction it gives the mind.

Finally, 行 makes impermanence intimate. “All conditioned formations are impermanent” is not merely a statement about civilizations collapsing or bodies aging. It means that the irritation now appearing, the identity now defended, and the apparent necessity of the next reaction are already in transition. The contemplative force of 諸行無常 lies here: what is constructed cannot provide an unconstructed refuge.

This recognition can initially feel unsettling. Eventually it becomes merciful. The painful pattern is not solid. The admired achievement is not safe enough to be a self. The wholesome practice is valuable but need not be possessed. One can care fully without demanding permanence from what cannot supply it.

Common Misreadings and Clarifications

“行 means external action.”

Too narrow. Bodily action can be 行, especially in the category of bodily karma, but formation also includes volition, inclination, mental construction, and other conditioning factors. Silent resentment or generosity may be formative before either becomes visible behavior.

“The formation aggregate means thoughts.”

Also too narrow. Discursive thinking can participate in formation, but 想 is recognition or taking signs, while 行 centrally concerns formative and volitional activity. Neither should be translated indiscriminately as “thought.” Depending on the analytical system, the formation aggregate includes a range of wholesome, unwholesome, and ethically neutral conditioning factors.

“All occurrences of 行 mean karma.”

No. In dependent arising, 行 is specifically karmically formative activity, and Abhidharma sources can explicitly say that this link has karma as its nature. In the five aggregates, the scope is broader. In 諸行無常, 行 may refer to conditioned phenomena generally. In discussions of cultivation, it can mean practice. Context decides.

“If formations are empty, actions have no consequences.”

This reverses the meaning of emptiness. Formations are empty because they arise dependently and lack independent self-nature. Their dependence is precisely why one condition affects another. Emptiness denies an autonomous substance, not causal efficacy or ethical consequence.

“The banana-trunk image means formations are fake.”

The analogy means that no solid, independent core can be found when the formation aggregate is analyzed layer by layer. It does not mean that intentions are causally inert. A promise, grudge, or habit has effects despite lacking a permanent essence.

The correspondence must be kept exact: in the traditional five-aggregate series, 行 is compared to a banana trunk. It should not be merged into a vague claim that “the aggregates are like illusions.” Other aggregates receive their own images—form as foam, feeling as a bubble, perception as a mirage, formations as a banana trunk, and consciousness as an illusion. The point of the series lies partly in these distinct correspondences.

“Cessation of formations means becoming passive or unconscious.”

The cessation taught in dependent arising is the ending of ignorance-conditioned karmic formation and the suffering it perpetuates. It is not mere physical stillness, cognitive shutdown, or inability to respond. The sources themselves distinguish wholesome, purified, and undefiled activity from formations rooted in ignorance.

“Wholesome karma is already final liberation.”

Wholesome formation is essential, but favorable becoming is not identical with release from becoming. Meritorious and even highly refined meditative formations can remain conditioned when supported by ignorance and appropriation. Ethical and contemplative training prepares and supports wisdom; wisdom sees through the assumption of a permanent agent, possession, or result.

“Dependent arising is just a description of psychology in the present moment.”

That is an unwarranted narrowing. The tradition uses the link of 行 to explain karmic continuity and the conditioning of future birth, while some texts and contemporary teachers also apply the structure to moment-by-moment experience. Immediate psychological illustration can make the mechanism visible, but it should not erase the broader karmic framework.

“Because everything is conditioned, nobody is responsible.”

Buddhist responsibility does not require an unconditioned personal controller. A deed arises through conditions, becomes a condition for further experience, and can be restrained or cultivated through new conditions. Denying a permanent self removes metaphysical ownership; it does not erase intention, consequence, remorse, repair, or training.

“諸行 and 真如 are two separate realities.”

The *Buddha’s Explanation of the Profound Secrets Sūtra* refuses both crude identity and crude separation. Suchness and formations are described as beyond the alternatives of one and different. Suchness is not another object hidden elsewhere; it is realized through seeing conditioned phenomena without the distortions of fixed essence and grasping.

“行 and 止 simply mean being busy versus sitting still.”

In the *Mūlamadhyamakakārikā* discussion, 行 signifies conditional continuation, while 止 signifies cessation: with ignorance, formations continue; with the cessation of ignorance, formations cease. A motionless person may still sustain powerful mental formation, while an awakened person may act vigorously without perpetuating ignorance-driven bondage.

The deepest importance of 行 is therefore not that it supplies one more item for a Buddhist vocabulary list. It identifies the hinge between conditioning and freedom.

We inherit conditions we did not choose. We then respond through intentions that become conditions in turn. When ignorance governs this process, formation carries experience toward grasping, becoming, and suffering. When ethical discipline, concentration, and wisdom illuminate it, the same field becomes the place of practice. Finally, even wholesome practice is known as conditioned and is not appropriated as self.

So the liberating question is not merely, “What action should I take?” It is:

What is being constructed now, from what conditions, toward what result—and am I taking this construction to be myself?

To see that clearly is already to loosen the banana trunk’s imaginary core. To cultivate the conditions of non-greed, non-hatred, and non-delusion is to redirect the stream. To understand formation completely is to approach the point where the stream no longer needs to manufacture an owner in order to flow—and no longer manufactures suffering through trying to keep one alive.
