What this concept is saying（这个概念在说什么）
因力 (*hetu-bala*, “the power of a cause”) is the capacity produced by previously approaching and repeatedly cultivating wholesome qualities, through which corresponding wholesome states can later arise more readily.
The key phrase is not simply “cause,” but “previously approaching and repeatedly cultivating” (先时亲近、数数修习). Something has already been learned, inhabited, and strengthened. When suitable conditions later assemble, that prior cultivation exerts a real formative power.
The *Yogācārabhūmi Śāstra* (《瑜伽师地论》) supplies the broader definition of a cause:
“若由此为先，此为建立，此和合故，彼法生，或得、或成、或办、或用，说此为彼因。”
That is: when something serves as an antecedent and basis, and through an appropriate conjunction another phenomenon arises, is attained, completed, accomplished, or put into operation, the former is called a cause of the latter.
This prevents two opposite misunderstandings. A cause is not an empty label attached after the event; it genuinely conditions what can arise. But the result is not a finished object secretly stored inside the cause. The same treatise rejects the theory that the fruit permanently pre-exists in its cause. A seed is capable of participating in the production of a sprout, but it does not contain a miniature sprout waiting to be unfolded. Soil, moisture, temperature, time, and the seed’s continuing transformation must converge.
因力 is therefore best understood as cultivated causal readiness. It is neither a hidden substance nor an irresistible fate. Previous cultivation has altered the field of possibilities: under supporting conditions, a corresponding state can arise more quickly, firmly, or naturally than it otherwise would.
The classical materials apply this principle in several distinct frameworks.
First, in the *Abhidharmakośabhāṣya* (《阿毘达磨俱舍论》), 因力 has a precise and restricted role in explaining the arising of meditative absorptions. The treatise says:
“生上二界总由三缘，能进引生色无色定：一由因力，谓于先时近及数修为起因故。”
Here it means that beings born in the two higher realms can enter form-realm or formless-realm concentrations because they had previously drawn near to and repeatedly cultivated those attainments. Familiarity with concentration has become a cause for concentration’s renewed arising.
This 因力 must be distinguished from the other powers in the same passage:
- 业力 (*karma-bala*, karmic power) concerns previously performed karma capable of producing birth in a higher realm. As its maturation approaches, it impels the arising of the corresponding concentration.
- 法尔力 (*dharmatā-bala*, power of the regularity of phenomena) concerns a cosmological regularity: when a world-system is approaching destruction, beings of lower realms naturally develop the concentration needed to reach a higher realm.
- 教力 (*śikṣā- or instruction-based power*, here “power of teaching”) explains how a desire-realm being enters a higher concentration through instruction. The *Kośa* does not indiscriminately apply the preceding three powers to every case of entering absorption.
The scope is carefully differentiated. For beings in the form and formless realms who generate formless concentration, the explanation employs causal power and karmic power, but not the cosmological power connected with the destruction of lower worlds. For a form-realm being generating meditative absorption, all three may apply. For a desire-realm practitioner entering a higher concentration, the passage instead speaks of 教力. Thus 因力 is not a universal synonym for “whatever caused meditation.” It is one specifically identified condition within a particular Abhidharma analysis.
Second, the *Yogācārabhūmi* applies 因力 to entry into the meditative absorptions, defining it concisely as “曾邻近入静虑等”: one had previously come near to, or entered, meditative absorption and related attainments. In this classification it appears alongside:
- 方便力 (*upāya-bala*, power of present method or applied practice): the effort and practical means being cultivated now;
- 说力 (power derived from teaching or retained exposition): support from learning and retaining the teaching;
- 教授力 (power of personal instruction): guidance given by a teacher.
The contrast is important. 因力 is established cultivation bearing upon the present; 方便力 is what one is presently doing; 说力 concerns assimilated teaching; 教授力 concerns guidance presently received from another. These conditions can cooperate, but they are not interchangeable.
Third, the *Yogācārabhūmi* uses 因力 in its account of the arising of bodhicitta—菩提心 (*bodhicitta*, the resolve for unsurpassed awakening for the benefit of beings). Here it says:
“诸菩萨宿习大乘相应善法，今暂得见诸佛菩萨，或暂得闻称扬赞美，即能速疾发菩提心。”
Because bodhisattvas have previously cultivated wholesome qualities corresponding to the Mahāyāna, briefly seeing buddhas or bodhisattvas, or briefly hearing them praised, can occasion the swift arising of bodhicitta.
In the traditional doctrinal setting, 宿习 (“prior habituation”) can include cultivation in previous lives; it should not simply be reduced to childhood conditioning or implicit memory in the present life. At the same time, the causal pattern is intelligible within ordinary present-life practice: what has repeatedly been valued and enacted becomes easier to reawaken.
This passage classifies four powers:
- 自力 (*sva-bala*, one’s own power); - 他力 (*para-bala*, the power of others); - 因力, the power of previous cultivation; - 加行力 (*prayoga-bala*, the power of deliberate application).
It further states that bodhicitta arising through one’s own power, causal power, or their combination is firm and unmoving, whereas a resolve arising only through others’ influence or present exertion is not yet comparably stable. This does not make help from others or deliberate effort worthless. It means that inspiration borrowed from outside and enthusiasm maintained solely by exertion have not yet become deeply established dispositions. Today’s 加行力, if sustained, may help form tomorrow’s 因力.
Fourth, the *Yogācārabhūmi* includes 因力 among four powers through which 善法欲 (*kuśala-dharma-chanda*, the wholesome desire or aspiration for wholesome qualities) arises: 缘力, 因力, 智力, and 行力—the power of supporting conditions, prior causes, understanding, and practice. Here again, wanting the good is not treated as an inexplicable mood. Wholesome aspiration has conditions; it can be educated, supported, enacted, and made increasingly available.
These uses share one structure: earlier wholesome cultivation becomes capable of eliciting a corresponding later state. But their results differ—meditative absorption, bodhicitta, or aspiration toward wholesome qualities—and each occurs within its own classificatory framework. We should preserve those differences rather than turning 因力 into a vague slogan about “the power of habit.”
It is also not a seventh member of the 六因 (*ṣaḍ-hetavaḥ*, six causes) taught in the *Abhidharmakośa*: 能作因, 俱有因, 同类因, 相应因, 遍行因, and 异熟因. The six causes classify types of causal relationship among phenomena. 因力 in the present passages identifies the efficacy of previously cultivated familiarity in specific paths of practice. The words overlap, but the analytical level is different.
Its position on the path of liberation can now be stated more clearly. The Buddhist path does not depend on waiting for a single overwhelming revelation. Hearing, reflection, ethical restraint, generosity, meditation, and the cultivation of compassion establish causes. Repetition changes what the mind can readily do. A wholesome state that initially requires reminders, instruction, and considerable effort may later arise swiftly and remain steady. 因力 names this continuity of cultivation—but never apart from supporting conditions, present practice, and discernment.
A walk-through in everyday life（生活里的走查）
Consider a commuter on a crowded train. Someone pushes past her, steps on her shoe, and does not apologize. Irritation appears immediately.
Suppose she has spent months practising a short sequence: noticing bodily tension, recognizing unpleasant feeling, refraining from instant retaliation, and deliberately considering that other people may be frightened, distracted, or exhausted. She has not merely agreed that patience is admirable. She has repeatedly approached and cultivated patience, mindfulness, and non-harming.
Now walk through the event carefully.
1. The jolt, bodily discomfort, noise, crowding, and another person’s movement are present conditions. They are not themselves 因力. Calling every contributing factor “causal power” would erase the term’s specific meaning.
2. The unpleasant feeling and angry impulse are also not 因力. They are presently arisen experiences. In particular, 因力 does not mean “whatever forceful emotion happens to arise.”
3. Her previous repeated cultivation is the relevant causal readiness. Because she has rehearsed recognizing agitation without immediately obeying it, mindfulness now becomes available sooner. That established familiarity is the closest everyday analogue to 因力.
4. Her present act of returning attention to bodily tension and refraining from harsh speech is current application—closer to 方便力 or 加行力 than to 因力. Present effort and prior cultivation work together, but should not be collapsed into one category.
5. A remembered teaching about patience supplies another kind of support. Advice from a meditation teacher, therapist, or spiritual friend is present instruction, not prior causal power as such.
6. The result is not guaranteed. On a day of illness, grief, or extreme fatigue, anger may still win. This does not prove that earlier practice was unreal. It shows that 因力 operates through conditioned conjunction, not mechanical determinism.
7. If she repeatedly completes the sequence without retaliation, current practice further establishes the causes that will condition future responses. What is difficult today can become more accessible tomorrow.
Now take a second scene: late at night, a person is scrolling through short videos. An account shows quiet, unsentimental work caring for displaced families. He pauses and feels an unexpectedly strong wish to help.
The video is a present supporting condition. The recommendation algorithm delivered it, but the algorithm is not thereby identical with 因力. Perhaps this person has long cultivated generosity, listened carefully to teachings on compassion, volunteered, and repeatedly tried to understand suffering beyond his own circle. That prior cultivation helps explain why a brief encounter can awaken a strong and coherent resolve rather than merely a passing emotion.
This resembles the structure of the *Yogācārabhūmi* passage on bodhicitta: prior cultivation of Mahāyāna-corresponding wholesome qualities allows a brief sight or hearing to occasion swift aspiration. But the ordinary wish produced in this example should not automatically be labelled full bodhicitta. Bodhicitta has a specific scope: unsurpassed awakening for the sake of beings. Compassionate emotion, charitable intention, and bodhicitta are related but not identical.
The distinction also reveals a common mapping error. The moving video is not “the cause” in the full sense merely because it appeared immediately before the wish. It may be a trigger or supporting condition. The depth, direction, and stability of the response depend in part on what has already been cultivated. Conversely, long familiarity without a present occasion may remain dormant. Prior cause and current conditions meet; neither should be mistaken for the whole explanation.
A third example concerns meditation. A parent has only ten quiet minutes after putting a child to sleep. At first, settling the mind requires instructions, a timer, repeated adjustment, and deliberate effort. After years of sound practice, attention may gather more quickly when the same person sits down.
The earlier repeated acquaintance with collectedness corresponds to the core pattern of 因力. The method used tonight corresponds more closely to present skilful means. A teacher’s correction belongs to instructional power. It would nevertheless be an overreach to claim that ordinary ease in meditation is one of the specific higher absorptions discussed in the treatises. The everyday example illuminates the causal structure; it does not certify a classical attainment.
Why contemporary people need it（当代人为什么需要它）
Contemporary life encourages us to explain ourselves through moods: “I am motivated today,” “I have lost discipline,” “I am simply an anxious person,” or “I am not naturally compassionate.” 因力 offers a subtler view. What feels spontaneous often has a history. Availability is cultivated.
This is hopeful because the path does not demand that wholesome responses be effortless at the beginning. If patience currently needs a reminder, if meditation requires structure, or if concern for others is easily displaced by self-protection, present difficulty is not a final identity. Repeatedly approaching a wholesome quality is already causal work.
It is also sobering because repetition is never neutral. The classical term here concerns previously cultivated wholesome qualities in specific doctrinal contexts, so it should not simply be redefined as any habit whatsoever. Yet the wider causal lesson is relevant: what we repeatedly attend to, endorse, and enact becomes increasingly available. Algorithmically curated life intensifies repetition. Outrage, comparison, craving, and distraction can be rehearsed hundreds of times without our naming them “practice.” Platforms do not need to control the mind absolutely; they need only keep supplying conditions under which certain responses are repeated.
AI provides a useful but limited comparison. A system’s output is shaped by prior training and by its present input. Likewise, earlier cultivation and present conditions both matter in human practice. But the analogy stops quickly. Buddhist analysis concerns ethically charged mental continuities, intention, karma, liberation, and—in its traditional setting—continuity across lives. A machine-learning model is not evidence for those doctrines, and current science has not established that computational training and Buddhist cultivation are the same kind of process.
Neuroscience likewise suggests that repeated activity can alter patterns of attention and response, but it neither exhausts the Buddhist account nor proves 因力. The relation between neural change, conscious experience, ethical agency, and contemplative attainment remains philosophically and scientifically unsettled. Such findings may help contemporary readers appreciate that practice can have lasting effects; they cannot determine the full meaning of a scholastic Buddhist category.
Most importantly, 因力 corrects an event-centred picture of liberation. We often imagine transformation as a dramatic insight occurring in isolation. Buddhist cultivation certainly recognizes decisive insight, but insight itself depends upon conditions: ethical preparation, steadiness, investigation, hearing, reflection, and repeated acquaintance with wholesome states. 因力 highlights the accumulated readiness through which the path becomes practicable.
It also explains why admirable inspiration is not yet enough. A retreat, book, teacher, illness, birth of a child, or encounter with suffering may suddenly open the heart. But if the response depends wholly on an external stimulus, it may fade when the stimulus disappears. The *Yogācārabhūmi*’s distinction between 因力 and 他力 is therefore psychologically penetrating: another person can awaken us, but borrowed momentum is not yet stable realization. Repetition must turn an occasional response into an established capacity.
This does not glorify self-sufficiency. Teachers, communities, texts, rituals, and supportive circumstances remain indispensable. Their role is partly to provide the conditions under which wholesome states can be approached again and again. Over time, what was initially supported from outside may become deeply rooted without ceasing to be conditioned.
At the deepest level, 因力 belongs within dependent arising rather than within a doctrine of a permanent self. Practice does not polish an immutable inner owner until “my true power” appears. Earlier conditioned events shape later conditioned events. Because the stream is conditioned, it is neither fixed nor arbitrary. Liberation is possible precisely because greed, hatred, delusion, generosity, concentration, and wisdom do not arise without causes.
Thus 因力 carries both responsibility and freedom. We inherit the tendencies established by prior cultivation, but present cultivation is already participating in what the future will inherit.
Common misreadings and clarifications（常见误读与澄清）
“因力 means willpower.”
No. Willpower usually means present exertion or self-control. In the relevant passages, 因力 primarily concerns a power already established through previous approach and repeated cultivation. Present exertion is closer, depending on the framework, to 方便力 or 加行力. Effort can help create causal power, but effort and established causal readiness are not identical.
“因力 is just habit.”
This is a helpful first approximation but too broad. Habit can include automatic posture, addiction, prejudice, or a morning routine. The classical passages concern prior familiarity with particular wholesome states—especially meditative attainments, Mahāyāna-corresponding qualities, and the arising of wholesome aspiration. Moreover, 因力 is analysed in relation to a corresponding result and within specific sets of conditions; it is not a general premodern word for every behavioural habit.
“The strongest impulse reveals what I previously cultivated, so I should obey it.”
No. A forceful impulse may arise from affliction, fear, bodily stress, social conditioning, or many other conditions. Strength is not proof of wholesomeness, and spontaneous appearance is not proof that the impulse exemplifies the 因力 discussed here. Buddhist practice still requires ethical and cognitive discernment.
“If 因力 is present, the result must occur.”
No. The *Yogācārabhūmi* defines causation through antecedence, establishment, and conjunction. A relevant cause operates when conditions come together. 因力 is causal efficacy, not an unconditional guarantee. Supporting or obstructing conditions remain significant.
“The result was already hidden inside the cause.”
No. This is precisely the kind of view challenged by the rejection of 因中有果论—the theory that the fruit permanently exists within its cause. The result arises dependently when causes and conditions converge; it is not a preformed entity extracted from storage.
“因力 and 业力 are two names for the same thing.”
No. In the *Abhidharmakośa* passage, they are separately defined. 因力 is the efficacy of previous approach and repeated cultivation; 业力 concerns previously performed karma capable of ripening as higher-realm birth and impelling the corresponding concentration as that maturation approaches. They can cooperate without being interchangeable.
“因力 is the same as 法尔力.”
No. 法尔力 in this context is the regular power by which lower-realm beings naturally develop higher concentration as a world-system approaches destruction. It is a cosmological condition, not the practitioner’s prior repeated cultivation.
“Every instance of entering meditation is explained by 因力.”
No. The *Kośa* carefully limits the classification. Its explanation varies with the realm in which the being is born and the concentration being generated. Desire-realm practitioners entering higher concentration are said in this passage to do so through 教力. The *Yogācārabhūmi* supplies yet another fourfold analysis—因力, 方便力, 说力, and 教授力. One should not combine these distinct lists into a single undifferentiated theory.
“因力 is one of the *Abhidharmakośa*’s six causes.”
No. The six causes classify causal relations among dharmas. 因力, as used here, describes the capacity of prior cultivation to elicit a corresponding later state. It is neither an additional seventh cause nor merely another translation of one member of the six.
“Prior cultivation means only experiences earlier in this present life.”
That restriction would narrow the classical meaning. In the bodhisattva account, 宿习 is situated within the Buddhist framework of continuity across lives. Present-life repetition can illustrate the structure, but it should not silently replace the traditional doctrinal scope.
“因力 proves that progress is linear.”
No. A well-established capacity may still be obscured by illness, exhaustion, trauma, adverse circumstances, or competing tendencies. Practice can ripen unevenly. 因力 explains why cultivation is not lost without implying that every day must look better than the preceding one.
“The lesson is simply to repeat something as often as possible.”
Repetition alone is not sufficient. The repeated object must be wholesome and rightly understood; method, instruction, discernment, and supporting conditions matter. Repeated strain can strengthen aversion, and repeated spiritual performance can strengthen conceit. The path is not brute conditioning but cultivation guided by right view.
The practical wisdom of 因力 is therefore quieter than the promise of instant transformation. Draw near to what is wholesome. Understand it correctly. Practise it repeatedly. Receive instruction, arrange supportive conditions, and apply present effort. Do not demand that a new capacity feel natural immediately. With continued cultivation, what once appeared only under exceptional circumstances can become easier to awaken and harder to dislodge.
That is where 因力 stands in the path of liberation: not as destiny, not as mystical stored energy, and not as a substitute for present practice, but as the accumulated efficacy through which wholesome aspiration, concentration, and the resolve for awakening become increasingly available. The path bears fruit because cultivation leaves causal consequences—and because conditioned tendencies, having arisen through causes, can also be redirected through causes.
