There is a moment almost everyone knows. You sit down on a Sunday evening and resolve, genuinely, that starting tomorrow you will rise early, exercise, meditate, finish the project, call your parents. The resolution is real. The will is present. By Wednesday the resolution has dissolved into the noise of the day — and you cannot quite say when, exactly, it dissolved. Something was missing. Not enthusiasm, not effort, not belief. Something more like the capacity of the mind to *stay consolidated* in what it has undertaken, to actually carry it through.
The Buddhist technical term for that capacity is 意力 (mano-bala), often translated as "the power of mind-intention" or simply "mental power." It sits at a very particular spot in the architecture of the path, and that spot — between the warm-up phase of faith and diligence, and the deepening phase of concentration and wisdom — is precisely why contemporary readers find it hard to see, and yet desperately need it.
Let's walk it carefully.
一、这个概念在说什么
1. 名字本身已经在讲故事
梵文是 *mano-bala*。Mano 是 "意" — the directing, intending mind; the mind as volitional, as "I am about to do X." Bala 是 "力" — power, force, the capacity that does not get pushed around. So *mano-bala* literally is *the force of the intending mind*, the mind's power to actually direct, to actually land where it aims.
Here is the first subtle point that often gets lost. In most later Buddhist doctrinal writings — the Yogācāra abhidharma, the Sarvāstivāda abhidharma, the *Abhidharmakośa* — the third of the Five Powers is rendered as 念力 (smṛti-bala), the power of mindfulness/ recollection. Smṛti is *recollection, presence, keeping-in-mind*. Different word, different emphasis. *Smṛti* leans toward "the mind that stays present with what is." *Mano* leans toward "the mind that directs toward what should be done."
Bodhiruci's translation of the《大寶積經》(Mahāratnakūṭa Sūtra, T0310) deliberately uses 意力, not 念力. This is not a slip or a careless synonym. It is a distinct technical choice, and it tells us something important about how this particular sutra wants you to understand the third power: less as quiet presence, more as *directing thrust*. Less as "remember to be here," more as "your mind's intention has the strength to land."
That single terminological decision is the doorway into the whole concept.
2. 意力在哪里——五力之中的关键位置
五力 (pañca-bala) are part of the 三十七菩提分法 (saptatriṃśad-bodhipākṣika-dharma), the Thirty-Seven Factors of Enlightenment. They sit inside the fourth set of seven, alongside the Four Bases of Spiritual Power, the Five Limbs, the Eightfold Path, and so on.
The Five Powers are the matured form of the 五根 (pañca-indriya), the Five Spiritual Faculties:
| 五根 (Roots/Faculties) | 五力 (Powers) | |---|---| | 信根 (śraddhā) | 信力 | | 精進根 (vīrya) | 精進力 | | 念根 (smṛti) | 念力 (or, here, 意力) | | 定根 (samādhi) | 定力 | | 慧根 (prajñā) | 慧力 |
The metaphor baked into the system: a root, when small, can be overpowered by opposing conditions — doubt can smother faith根, laziness can smother diligence根. But when the root matures into a *power*, it can no longer be overpowered. 信力 cannot be defeated by doubt. 精進力 cannot be defeated by laziness. 意力 cannot be defeated by散乱 (scatteredness). 定力 cannot be defeated by agitation. 慧力 cannot be defeated by ignorance.
Notice the position. 意力 sits at the hinge. It is the third of five. Before it: faith and diligence — the motivational thrust that *gets you moving*. After it: concentration and wisdom — the deepening that *reveals truth*. 意力 is what happens in between. It is the moment when motivation stops being a hot spark and becomes a steady beam.
You can see why the《大寶積經》wants *意* rather than *念* here: this is the moment of *directing*, of mind-as-arrow-already-released-and-still-on-course. Not yet absorbed in the target (that is 定力), but no longer merely wanting the target (that is 信、精進).
3. 经典定义的核心
The sutra's own definition is short and worth chewing on:
「所當修者而皆行之，其意勢強，是為意力。」 *Whatever should be cultivated, one carries out; the force of one's mind is strong — this is mind-power.*
Three movements packed into one sentence:
- 「所當修者」 — "what should be cultivated." 意力 is not random force; it is force directed toward *what is appropriate to cultivate*. A mind with意力 is not a mind that grinds through arbitrary tasks; it is a mind whose directing force is aligned with the right object. - 「而皆行之」 — "and one carries it all out." 意力 is not just knowing or intending; it is the actual execution. The word *皆* (all, every one) is doing work: nothing is dropped, nothing is half-done, no item on the path is allowed to lapse. - 「其意勢強」 — "the势 (force/ momentum) of one's mind is strong." Here is the active side: 意力 is a *勢用*, a dynamic, propulsive quality of mind. Not a static asset, but a current.
Put together: 意力 is the mind's strong, directing momentum that actually carries out everything that should be cultivated.
4. 八個面向的展開
The sutra does not stop at one sentence. It then unpacks 意力 from eight angles, and these eight together form a portrait you can almost touch:
1. 「逮得總持不共道意」 — One attains dhāraṇī (總持, "total retention") and the *non-common* bodhi-intention (i.e., the bodhi-mind specific to a Buddha's awakening, not shared with ordinary beings). 意力 is connected to the memorization-and-integration faculty that holds the Dharma in mind. 2. 「具足解慧度知見力」 — 意力 is fulfilled with penetrative understanding (解慧) and the power of *liberating vision* (度知見力). So 意力 is not blind drive; it carries insight within it. 3. 「所顯德本勸助道心」 — 意力 *manifests* the virtuous roots and *urges forward* the bodhi-mind. It does not leave virtuous potential dormant. 4. 「具足道心令不闕漏」 — 意力 makes the bodhi-mind *complete, without gaps*. Nothing falls through. 5. 「修行於道而令具足」 — 意力 brings the path-cultivation itself to fulfillment. 6. 「常一其志而勸助之」 — 意力 keeps one's resolve unified (一其志) and uses that unified resolve to encourage and benefit others. Crucial: 意力 is not selfish isolation; it radiates outward. 7. 「嚴淨思念所行如應」 — 意力 adorns and purifies one's thoughts (思念), so that what one does is *as it should be* (如應). The mind's thoughts become clean because the directing force is clean. 8. 「心常整齊未曾憒亂」 — The mind 常 (always) ordered, never confused or stirred into muddiness (憒亂).
Read them together and you get a portrait: 意力 is unified, strong, gap-free, outward-radiating, insight-bearing, purifying, orderly. It is *the quality of a mind whose intention is intact across time*.
5. 終極的張力——意力歸於「無意無念」
And then the sutra does something startling. It closes the section with:
「清淨其意合集群類道品之法，無意無念，是為意力。」 *Purifying one's mind, gathering the manifold Dharma-factors of the path — no intention, no thought — this is mind-power.*
Wait. The whole exposition has been describing 意力 as *strong势用 (forceful momentum)*, a vigorous directing mind. Now the sutra says the *culmination* of 意力 is 無意無念 — no grasping at intention, no fixation on thought.
This is not a contradiction. It is the deep structure of the whole bodhisattva path, and the《大寶積經》here is using 般若性空 (prajñā-śūnyatā) to gather the Five Powers back into itself.
The logic: an intention that is still grasping itself as "my intention" is still operating in the realm of clinging. An intention that has matured to the point where it functions perfectly *without needing to grasp itself* — that is 意力 come to rest. Like an archer who, after decades of practice, no longer needs to *think* about releasing the string. The skill has become transparent.
意力 matures into 意力 that does not hold itself as 意力. The force remains — in fact, it is most fully operative — but the ego-grasping on the force is gone.
This is the same pattern you see in《金剛經》's 「應無所住而生其心」 ("the mind should arise without abiding anywhere"). Same principle, different formulation: a heart that is fully alive, fully functional, but not gripping at any of its own contents.
6. 同源「意」系概念：性空而用強
The《大寶積經》also mentions two related concepts that give the term 意力 its context within the "意" family:
- 意界 (mano-dhātu) — the mental element, the sixth of the eighteen dhātus. The sutra says of it: 「意界不可得……但以於假名，說有種種相」 — "the mental element cannot be found as a thing… it is only by way of provisional names that various characteristics are spoken of." 意 is fundamentally *unfindable* as a substance. - 意業 (manas-karman) — mental karma, the volitional formation that happens in mind alone. The sutra says: 「意業是佛地，愍觀眾生故」 — "mental karma is of Buddha-ground, because of compassionate observation of beings." 意業 can reach all the way to Buddhahood.
So the family picture is: 意 is empty of self-nature (意界不可得), yet functionally potent enough to reach Buddhahood (意業是佛地). 意力 (mano-bala), the cultivated power of this mind, is precisely the mature form of this empty-yet-potent capacity.
You cannot understand 意力 without this dual signature: 性空而用強 — *empty in nature, powerful in function*.
二、生活里的走查
Let me ground this. I'll use three scenes, each chosen because it reveals a different facet of 意力, and I'll mark clearly where the sutra's classical definitions are being mapped (and where people most often map them wrong).
場景一：周一早晨的每日靜坐承諾
It is Sunday night. You have decided — really, this time — to meditate twenty minutes every morning for the next three months. You have read the books, you have listened to the teachers, you have *信* (genuine confidence this matters). You have made the *精進* resolve (you set out the cushion, you told your partner). Monday morning, you actually sit. Tuesday, you sit. Wednesday, you snooze. Thursday, you sit grudgingly. Friday, you don't.
Walk through this with the sutra's definitions:
- 「所當修者而皆行之」: "What should be cultivated" is the daily sit. "All carried out" is what failed. The gap between them is exactly where 意力 was missing. 精進 got you through Monday and Tuesday. By Wednesday, the spark had died, and nothing in you *landed* on the cushion. - 「其意勢強」:勢 (force/momentum) is the quality that was missing. Not force as in *trying harder*; force as in *the mind's directed momentum has not dissipated*. Imagine a thrown arrow that keeps flying straight: that is 意勢. Your Wednesday-morning mind was an arrow that started wobbly in flight. - 「常一其志而勸助之」: Your resolve kept *changing shape*. Monday morning your志 was "this is essential." By Thursday your志 was "I should probably do this, but also I need to check email first." Unification of志 is what 意力 gives; its absence is what made the practice fragment. - 「心常整齊未曾憒亂」: 整齊 — orderly. 憒亂 — muddied, confused. Wednesday's mind was not muddied in any dramatic way; it was just *muddied by ordinary wanting-to-sleep-more*. 意力 is the capacity for the mind to stay *整齊* (orderly) across small resistances, not just large ones. - 「嚴淨思念所行如應」: Your thoughts on Thursday morning — "I'm too tired," "Just five more minutes," "It doesn't really matter" — were not purified. They ran unfiltered. 意力 is what *purifies* the stream of inner talk before it determines action. - 「逮得總持不共道意」: Over months, a meditator develops dhāraṇī-like continuity — the teachings are not external rules but internal resonances. That is the cumulative result of意力 matured.
Common mapping mistake: People say "I need more willpower" or "I need more discipline." Those are translations of 精進 (vīrya), the second root/power. *精進 gets you to start. 意力 gets you to keep going.* The Sunday-night-resolve failure is not a failure of trying; it is a failure of *consolidated directing force over time*.
場景二：親密關係裡的「我應該更好」
A couple has been together eight years. There is love, but also accumulated small failures — the partner is tired, one partner is distracted, a comment that landed wrong. One evening, the other person says — calmly, kindly — "I think we are drifting." You hear it. You genuinely want to do better. 信 is there: you believe the relationship matters. 精進 is there: you make plans to be more present.
Three weeks later, the same drift. The same apology pattern. The same forgetting.
Map this onto 意力:
- 「具足道心令不闕漏」: 道心 here is not a religious path; it is the *heart-direction* toward the person you love. 意力 is what makes that direction complete without gaps. Its absence shows up as *lapse* — not in dramatic betrayal, but in small uncounted failures of attention. The little uncounted lapses are exactly where 意力 either lives or doesn't. - 「所顯德本勸助道心」: 德本 (virtuous roots) in this context = your accumulated good tendencies — patience, kindness, attentiveness. 意力 *manifests* them; without it, they stay latent, as "I would be a good partner *if*…" - 「具足解慧度知見力」: Knowing *why* you drift is not the same as having the *power* to land differently. 意力 bridges understanding and execution. - 「常一其志而勸助之」: Your志 toward the relationship was not *unified*. Part of you was for the relationship; part of you was for the comfortable drift; part of you was for the next distraction. 意力 is what enables 一其志 — one志.
Common mapping mistake: People call this "communication skills" or "relationship tools." Those are useful. But the deeper issue — *why knowing better doesn't translate into doing better over time* — is exactly what 意力 addresses. It is the bodhisattva-path version of "executive function for the heart," the capacity by which intention survives contact with the ordinary texture of life.
場景三：信息洪流裡的單一志
You sit down to write a report. The report is the only thing that matters for the next ninety minutes. You open the document. Then you open Slack to "check one thing." Then a notification. Then email. Then a thought about a podcast. Then you look up and forty minutes have passed and the report has three sentences.
This is the contemporary texture of 意力's absence:
- 「心常整齊未曾憒亂」: 整齊 (ordered) is the opposite of the scattered, notification-driven mind. The sutra was written in a quieter century, but the phenomenon is the same: a mind that is *整齊* is a mind with a single order of business at a time. - 「常一其志而勸助之」: Single志 is precisely what the attention economy is engineered to dismantle. Every app, every infinite scroll, every red dot is a small engine of志- fragmentation. 意力 is the countervailing force — not by fighting apps, but by *unifying one's own志* at a level apps cannot touch. - 「嚴淨思念所行如應」: 思念 (inner thoughts) before action. The thought that precedes the Slack-open is "just one thing, then back." 意力 is the capacity to *purify* that thought — to recognize it as the seed of drift and to choose differently before the click.
Common mapping mistake: We call this "focus" or "concentration" and reach for 定力 (samādhi-bala) — the fourth power, deep meditative absorption. But 定力 is downstream of 意力. You cannot *enter* absorption without first having a mind whose directing force is consolidated. Most "focus problems" today are actually 意力 problems wearing the costume of 定力 problems. You don't need a deeper meditative state; you need the directing mind to stop fragmenting before it ever reaches the door of meditation.
三、当代人为什么需要它
1. 我们活在意力破碎的時代
The contemporary environment is, structurally, an environment of *anti-意力*.
Every product in the attention economy — infinite scroll, autoplay, push notifications, short-form video — is designed to *fragment your directing mind into many small, easily-replaceable directives*. Each scroll is a tiny *意*; none of them last long enough to constitute *意力*. The cumulative effect is a muscle that has not been exercised: when you finally sit down with the one thing that genuinely matters, you find your *意* has lost the strength to hold itself in shape for more than a few minutes.
意力 is the antidote not by fighting the technology, but by cultivating a mind whose directing force has internal integrity. The Buddha's analysis was not about apps; it was about the structure of the mind. But the diagnosis turns out to be uncannily precise for our century: a fragmented意 is the default state of an untrained mind in a fragmenting environment. 意力 is the trained, mature alternative.
2. 意志力文化的局限
Contemporary self-help is built largely on the cult of *willpower* — the idea that if you just *try harder*, you can transform. The limits of willpower culture are well-documented: willpower burns out, willpower is locally depletable, willpower does not produce consolidation.
意力 is not willpower. Willpower is closest to 精進 (vīrya) — the *push*. 意力 is the *shape* of the mind that makes push sustainable. You can have a strong push on Monday morning and still not have 意力. 意力 is what makes the push unnecessary — or rather, what makes the push *spontaneous*, arising from a mind that is already unified.
The burnout of contemporary discipline culture is, at root, a 意力 gap mistaken for a willpower gap. People keep trying to push harder, when the actual training needed is *unification of the directing mind*, a fundamentally different project.
3. 「說到做到」是這個時代的稀缺品
Contemporary life is full of broken promises — to ourselves and to others. New Year's resolutions, project deadlines, relationships, practices, sobriety, exercise, reading plans. The cultural complaint is everywhere: *we can't follow through*. The Buddhist diagnosis cuts through the noise: the failure is not in trying; the failure is in 意力 — the capacity of the mind to maintain its directing shape across time.
A person with 意力 is not a person who tries harder. A person with 意力 is a person whose *intention has weight, has continuity, has落地 (the capacity to land)*. Such a person is rare in any era, and perhaps especially rare in ours.
4. 從「我想要」到「我在做」——橋本身就是稀缺品
The whole Five Powers sequence is a developmental arc:
- 信力 — I genuinely trust this path / this person / this work. - 精進力 — I push myself forward. - 意力 — My push becomes a *shape*; my intention consolidates. - 定力 — The mind becomes still and clear, gathered into one place. - 慧力 — Insight matures; wisdom cannot be overturned.
The transition from "I want to" (信、精進) to "I see clearly" (慧) cannot skip steps. Most contemporary attempts at transformation fail because they try to jump from step 2 to step 5 — from push to insight — without traversing the step-3 bridge that 意力 names. In a culture obsessed with both motivation and outcomes, the in-between stage of consolidation is the missing piece.
四、常見誤讀與澄清
誤讀一：意力 = 意志力
No. Willpower corresponds more closely to 精進 (vīrya) — the *push*, the exertion. 意力 is something more integrated: it includes the push but also the *unification, the continuity, the purification of the inner talk, the gap-free execution*. You can have strong willpower for a single afternoon. 意力 is what carries you through three years. They are related but distinct: 精進 is *how hard* you push; 意力 is *how consolidated* your pushing mind is over time.
誤讀二：意力 = 正念 / Mindfulness
This is the most consequential confusion, because the standard formulation of the Five Powers in later abhidharma literature uses 念力 (smṛti-bala), and "mindfulness" is the usual modern translation of 念.
The《大寶積經》(T0310) deliberately uses 意力 instead of 念力 here, and this is a real signal. *Smṛti* leans toward *presence, recollection, keeping-in-mind* — the mind that does not forget, that stays with what is in front of it. *Mano* in this sutra leans toward *intention-as-direction, mind-as-arrow*. The two are cousins, not twins.
The sutra's own descriptors for 意力 confirm the distinction: 「其意勢強」 ("the force of one's mind is strong"), 「常一其志」 ("unifying one's resolve") — these are about directing force, not just about *being present*. Contemporary mindfulness culture often emphasizes acceptance and non-grasping; 意力 in the《大寶積經》is about *consolidated directing thrust*. Both matter; they are not the same practice.
誤讀三：意力 = 入定 / Concentration
No. 意力 sits *before* 定力 in the sequence. 定力 is deep meditative absorption — the mind collected in one place. 意力 is what *enables* the mind to enter that collected state, but it is not the collected state itself. If you try to *concentrate harder* to fix a 意力 problem, you are skipping the prior step. The way most people try to "focus" today is a 定力 maneuver applied to a 意力 problem. It usually doesn't work, because the directing mind has not been consolidated yet.
誤讀四：意力 = 強烈的信念 / Strong opinions
No. 意力 is not about the *intensity* of one's views; it is about the *directing force* of mind toward what should be cultivated. You can have intense opinions and zero 意力 — your opinions may be a form of *見 (dṛṣṭi)*, view, which the bodhisattva path eventually also has to deconstruct. 意力 is *executional*, not *positional*. It does not say "I am right"; it says "the mind's directing force is intact, gap-free, and aimed at what should be cultivated."
誤讀五：「無意無念」等於不用力
Many readers, when they reach the closing line — 「清淨其意……無意無念，是為意力」 — read it as a contradiction or as "give up, let go, do nothing." It is neither.
**無意無念 is not the absence of force; it is the absence of *grasping* at force.** Mature 意力 functions fully without needing to clutch itself as "my intention." It is the difference between a beginner driver gripping the steering wheel with white knuckles and an expert driver whose hands rest on the wheel with the same effect. The wheel is still being directed. The grip is gone.
The《金剛經》's 「應無所住而生其心」 ("a mind that arises but does not abide") is the same gesture in a different idiom. 功能完整，執著全消 — *fully functional, fully unclenched*. This is what 意力 looks like when it has matured all the way through.
誤讀六：意力是一種靜態的「資產」
Because bala is translated "power," people imagine it as a fixed reservoir: "I have意力" or "I don't."
The sutra's 「其意勢強」 uses 勢 — *momentum, current, dynamic force*. 意力 is something a mind *has* at any given moment in a particular degree, and it can be cultivated, exhausted, restored. It is closer to *current fitness* than to *static strength*. You do not possess 意力; you practice your way into it, moment by moment, by repeatedly closing the gap between what should be cultivated and what you actually do. That gap-closing, repeated, is how 意力 builds.
A Closing Image
Think of 意力 not as a wall you build or a muscle you pump, but as the *grain* of a piece of wood. A wood with strong grain holds its shape under pressure; a wood with weak grain splinters. The bodhisattva path is the gradual alignment of the mind's grain — through 信 (trust), through 精進 (push), through the maturation that 意力 names, and onward into 定 (stillness) and 慧 (insight). The《大寶積經》's particular choice of *意* rather than *念* at this hinge suggests that what matters most at this step is not just *remembering to stay* but the *directing force* of the mind itself — its capacity to be one thing, fully, without scattering.
And the strange, liberating final note: when the grain is fully aligned, it becomes invisible. The wood just *does what wood does*. 無意無念 — no intention clutched, no thought held — and yet everything that should be cultivated is, without exception, carried out. That is 意力 come home.
