What this concept is really saying
Most people, when they first hear "Buddha's powers," picture something cinematic — a being who can read minds, fly through walls, or beam enlightenment into unwilling recipients. The classical Buddhist sources are doing something far more sober and far more unsettling. The *Daśatāla* (Ten Powers) of a Tathāgata are not siddhis; they are the structural shape of a mind that has fully seen how reality actually behaves. The sixth of these, 遍趣行智力 — literally, "the power of wisdom that knows the courses along which all conducts tend" — is about one very specific kind of seeing: *knowing which course of action leads where, and for whom*.
Let's unpack the name before unpacking the content, because the name itself carries the whole teaching.
- 遍 (sarvatra): "everywhere," "pervasively," "in all directions." It signals that this knowing is not partial or limited to some beings — it covers all of them. - 趣 (gāmin/gati): the "tending toward," the direction of motion. In Buddhist cosmology and soteriology, *gati* is what a stream of action is gravitating toward — a destination, an outcome, a kind of birth, a kind of mind-state. - 行 (pratipad/caraṇa): conduct, course of action, way of walking. Not just "behavior" in the behavioral-psychology sense; it is the *whole path of conduct*, including intention, mode of practice, and the inner disposition that drives behavior. - 智 (jñāna): wisdom-knowledge, not mere information. This is not a database query; it is an aspect of awakened cognition. - 力 (bala): "power" in the sense of an unshakeable, unoverthrowable capacity — the kind of knowing that cannot be defeated by counter-argument, by ignorance, or by passing time.
So the sixth Tathāgata-power is: *the unoverthrowable wisdom that knows, throughout all beings and all courses of conduct, where those courses are actually tending.*
Where this sits in the Ten Powers
The Ten Powers (十力, daśa bala) are not ten separate superpowers. They are ten facets of one total seeing. The first five build the foundation, and the sixth is where that foundation is applied to the question of *practice*:
1. 处非处智力 (power of knowing what is possible and impossible) — knowing the rules of the moral and causal landscape. 2. 业异熟智力 (power of knowing the ripening of actions) — knowing how specific deeds produce specific results. 3. 种种界智力 (power of knowing the various dispositions/realms) — knowing the "fields" or seed-natures of beings. 4. 种种胜解智力 (power of knowing the various intentions/resolves) — knowing what beings are aiming at. 5. 根胜劣智力 (power of knowing the superior and inferior faculties) — knowing the latent capacity of each being. 6. 遍趣行智力 — *knowing which course of conduct leads where.*
The fifth power tells you *what capacity a being has*. The sixth power tells you *what path that capacity is actually walking, and what that path produces*. The two together answer a question every serious teacher eventually faces: *given the person in front of me, what kind of practice will actually work for them — and what kind is, frankly, a waste of their time and mine?*
The two classical expositions, and why they don't quite say the same thing
The *Mahāratnakūṭa Sūtra* (《大寶積經》) and the *Yogācārabhūmi Śāstra* (《瑜伽師地論》) both expound this power, but they angle the spotlight differently. The differences are not contradictions; they are two valid ways of carving up the same total knowledge.
**The *Mahāratnakūṭa* approach — uses the term 諸行** ("all conducts") and structures the teaching around *who* the being is and *what kind of conduct they are running*:
- Three determinate natures (三種定之性): - 正定之性 — the "certain-to-attain" nature, produced by cause-power, prior-life preparation, and the opening of sharp wisdom-faculties. The Tathāgata knows this being is ready and teaches accordingly for swift liberation. - 不定之性 — the "uncertain" nature, ripened by external conditions. With proper instruction they awaken; without it, they don't. - 邪定之性 — the "fixed-in-delusion" nature, veiled by afflictions, with weak consciousness, deep ignorance, caught in the net of wrong views. Even the Buddha's teaching will not directly liberate such a being in this very life. The Tathāgata knows this and sets them aside — not in contempt, but because a different medicine is needed.
- Three greed-conducts (三種貪行): the mode of grasping after beauty (*淨美相*), the mode of clinging-attachment (*愛戀相*), and the mode driven by prior-life causes (*先世因*). - Three hatred-conducts (三種瞋行): the mode of seeking to harm (*損害相*), the mode of trained/deliberate hostility (*委練觀察*), and the mode erupting from prior-life latencies (*先世隨眠*). - Three delusion-conducts (三種癡行): from fundamental ignorance (*因無明*), from a false sense of self (*因妄有身見*), and from doubt (*因疑*).
- Four combinations of painful/easy conduct with sharp/dull faculties: painful conduct can pair with either sharp or dull faculties; easy conduct likewise. A being can be doing real ascetic work with a sharp mind, or doing real ascetic work with a confused one; likewise for comfortable practice.
- Four combinations of slow/fast walking and slow/fast arriving (四種行修之遲速): slow-walking/slow-arriving, slow-walking/fast-arriving, fast-walking/slow-arriving, fast-walking/fast-arriving. The *Mahāratnakūṭa* explains these through abandoning the object of focus (*捨所緣*), maintaining the path without interruption (*道不息*), resolute advance (*勇決進*), or being constitutionally of a different nature (*非彼性*).
- Analysis of discriminative power versus cultivation power (簡擇力 / 修習力): whether a being has strong analytical understanding but weak sustained practice, or vice versa, and the four combinations thereof.
- The three-fold summary of all conduct — the most arresting line in this section: every course of conduct that any being is on falls into one of three buckets: - 流转 (*saṃsāra*): conduct that keeps one turning in the cycle. - 不流转: conduct that turns one *out* of the cycle. - 流转及不流转: conduct that does both — moves one forward in some respects and keeps one bound in others. Most real human practice lives in this awkward middle category.
The sutra ends with a striking claim about the magnitude of this knowing: it is *acintya* (不可思議), unbounded, equal to space itself.
**The *Yogācārabhūmi* approach — uses the term 行跡** ("paths of practice," "trails") and structures the teaching around *the destination of the path*:
- The Tathāgata knows which paths lead to which of three outcomes: - 能令離染: paths that liberate a being from the stains (defilements). - 能令畢竟清淨: paths that produce *ultimate* purification — full awakening, with nothing left over. - 但令不畢竟清淨: paths that produce only *provisional* purification — a temporary cooling of defilements that does not arrive at final freedom.
That last category is the most important one for our age. Many sincere practices produce real relief and even real virtue without producing liberation. The *Yogācārabhūmi* is willing to say so plainly.
- The *Yogācārabhūmi* also distinguishes four kinds of seed (四種種子) that determine whether a path can be effective at all: 本性住種子 (intrinsic seeds), 先習起種子 (seeds from prior training), 可修治種子 (seeds that are *remediable* — these are the seeds of beings who have the Dharma-nature, *般涅槃法*), and 不可修治種子 (seeds that cannot be remedied in this lifetime).
- It also explicitly folds into this sixth power the knowing of 前際因緣 — the past causes that are running alongside present conduct. This is why the power is described as *pervasive* (遍): it spans past, present, and the directional pull toward future outcomes.
- Crucially, the *Yogācārabhūmi* also notes that this and all the Tathāgata-powers are classified as 世俗智 ("conventional wisdom") — they are *about* ultimate reality but are themselves still conventional cognitions — and yet they are 無漏 ("undefiled," not contaminated by afflictions). It also notes that these powers exist in the continuum of arhats as well as the Tathāgata, though the Tathāgata knows them "in the manner appropriate to a Tathāgata."
The connection to the Fourth Power
The sixth power is most intimately linked to the fourth power, 種種界智力 (the power of knowing the various realms/dispositions). The *Yogācārabhūmi* is explicit: once you have correctly known the *kinds of beings* (their seed-nature, their disposition), the next step — knowing the *paths those beings are actually walking* and where those paths lead — is the sixth power. They are sequential and continuous: knowing the seed, then knowing the trajectory of that seed's unfoldment into conduct and outcome.
This is why placing the sixth power here in the sequence makes sense. By the time the Tathāgata has examined your latent nature, your karmic ripening, your conscious intentions, and your faculty-strength, the question naturally becomes: *given all of that, what path are you actually on, and where is it actually taking you?*
Walking it through in life
Let me take this into some scenes you would recognize.
Scene 1 — A couple in their forties at a retreat.
They came for different reasons. She came because her therapist told her she needed "a mindfulness practice"; he came because his company was going through layoffs and he heard meditation "helps with focus." On the surface they are doing the same retreat. The sixth Tathāgata-power would say: these are not the same course of conduct.
Her conduct is 不流转及流转 — partly turning toward liberation (she is sincerely investigating the mind), partly still turning in samsara (she is using the practice instrumentally, as a coping tool, and is unwilling to look at the actual attachments that brought her to therapy). She has sharp faculties but her discriminative power (簡擇力) exceeds her cultivation power (修習力) — she sees clearly but doesn't yet stay in the sitting.
His conduct is closer to 流转 at the moment — not because meditation is bad, but because his *intention* is subordinated to career anxiety. The retreat is, for him, a means to an economic end. The course he is walking is pointed at re-entering the job market with better cognitive function. Until the intention underneath changes, the path he is on produces only 不畢竟清淨 — a temporary cooling, not ultimate purification.
If a teacher with the sixth power were advising them, the advice would diverge sharply — even though both are sitting in the same room doing the same practice.
Scene 2 — A friend who has "tried everything."
Meditation. Therapy. Yoga. Plant medicine. Stoicism. CBT. Buddhism. Christianity. A year in the monastery followed by two years as a DJ. She reads about every tradition and tries each for six months. From the outside she looks like a deeply sincere seeker. From the inside she feels like nothing has stuck.
The *Mahāratnakūṭa*'s four-fold 行/修 analysis is exactly diagnostic here. She is 速行 (fast-walking) — switching paths rapidly. She is also 速通 in some respects — she picks up frameworks quickly. But the pairing 速行遲通 (fast-walking, slow-arriving) actually describes her whole life: lots of motion, no arrival. Why? The *sutra* would say 捨所緣 (she abandons the object of focus before it can ripen) and possibly 非彼性 (her fundamental disposition is such that no single path can carry her all the way without radical re-orientation of intention).
The sixth power does not predict. It diagnoses structure.
Scene 3 — A sincere activist who burns out.
She is fighting climate change, working eighteen-hour days, sacrificing sleep and relationships, deeply committed. After five years she collapses into depression. Friends say "you burned out"; her therapist says "set boundaries." But the sixth power would say something more precise: she was on a course of conduct that was 流转及不流转 — partly genuine, partly self-binding. The activism was genuinely turning her *toward* a more awakened relation to others; but the underlying conduct — driven by the greed-conduit of 愛戀相 (clinging to the world she wants to save), the hatred-conduit of 損害相 (wanting to harm those she sees as obstructing it), and the delusion-conduit of 妄有身見 (identifying as "the one who saves") — was also tightening the knot.
A path with 不畢竟清淨 as its ceiling. Real purification, not final liberation.
Scene 4 — A person who has settled into "I am spiritual but not religious."
They meditate, they read widely, they are kind, they are calm. They have no desire to join a sangha, take refuge, or engage a teacher. They believe they have "found their own path." The *Mahāratnakūṭa*'s three natures is precisely diagnostic here. They are likely 不定之性 — the "uncertain" nature. With proper external conditions (a teacher, a community, a coherent doctrine to test their intuitions against), they would ripen into liberation. Without those conditions, the practice produces only provisional purification. They will not fall into the deep suffering of a wrong-view-entangled life, but they will also not arrive.
Scene 5 — The would-be guru.
A charismatic teacher has built a following of several hundred. The teachings are a bricolage of Buddhism, NLP, conspiracy theory, and self-help. He genuinely believes he is helping people. From within the sixth power: he is 邪定之性 for the most part — his consciousness is thin, his ignorance deep, he is caught in nets of wrong view. *But the sutra is careful*: this does not mean his students are wasted. Some of them have their own seeds and will, through contact with him, ripen into genuine seeking that takes them elsewhere. The Tathāgata knows this and does not waste effort debating the guru himself, but continues to teach the students who are ready.
The point of all five scenes
The walking-through is showing the same thing: most of what people call "spiritual practice" is not on a single path with a single destination. Different people in the same room are on different courses, and those courses have structurally different ceilings. The sixth power is the Tathāgata's perfect clarity about exactly this. A teacher with even a sliver of this power — far short of Tathāgata-knowledge, but in the same direction — teaches differently to each of these five people, even though the surface form of the teaching looks similar.
Where the popular mind easily maps this concept wrong:
- Mapping it to "the Buddha knows my past lives." That is the third power's neighbor, 宿住隨念智力, not this one. This sixth power is about *present conduct and its structural trajectory*, not about past-life memory. - Mapping it to "the Buddha knows what I should do." Closer, but still off. The sixth power knows *where your existing path is heading* and *what kind of path would suit your nature*. It is structural, not prescriptive of specific actions. - Mapping it to "the Buddha will save everyone." This is the most common misreading of the three natures. The sutra is explicit: beings of 邪定之性 cannot be liberated by the Tathāgata's teaching alone in this very life. The Bodhisattva-path (which the sutra immediately mentions) exists precisely to reach these beings over longer stretches of time and by entering their worlds directly. The Tathāgata's *knowledge* is total; the Tathāgata's *remedial reach* into a specific being's liberation is conditioned by that being's seed-nature.
Why contemporary people need this
The contemporary condition has a peculiar feature: we have more techniques available than at any previous point in human history, and we are less able than ever to discern which technique actually does what.
The shelves of every major city are stocked with mindfulness apps, psychedelic-assisted therapy programs, Stoic handbooks, CBT workbooks, IFS manuals, somatic experiencing protocols, Tibetan visualizations, Zen aphorisms, Hindu deity devotions, Qi Gong lineages, and AI-coached cognitive reframing tools. Each of these is a course of conduct. Each produces a specific kind of outcome. Almost no one is in a position to see clearly which one leads where, for whom, and to what ceiling.
This is exactly the situation the sixth Tathāgata-power is *about*. We are drowning in 行跡 (paths of practice) while having lost access to anyone who can reliably tell us their destinations. The classical exposition is, in this light, not an abstract scholastic taxonomy but a desperately needed diagnostic vocabulary.
A few specific places where this concept lands with force in contemporary life:
1. The collapse of discernment between "therapeutic" and "liberating" paths. Modern mental-health interventions are extraordinarily good at producing 不畢竟清淨 — real relief from anxiety, depression, trauma, addiction. They are not designed for and generally do not produce 畢竟清淨 — freedom from the underlying structures of self-clinging that produce those conditions in the first place. Conflating the two is one of the defining spiritual errors of our era. The sixth power's three-outcome taxonomy was articulated precisely to prevent this confusion.
2. The spiritual bypassing of activism and vice versa. The contemporary activist who refuses any interior practice, and the contemporary meditator who refuses any engagement with collective suffering, are both operating inside 不畢竟清淨 ceilings. The sixth power's three-fold summary — 流轉、不流轉、流轉及不流轉 — gives a precise language for diagnosing why well-intentioned efforts fail to land where they aim.
3. The illusion that sincerity is enough. The four-fold 行/修 analysis makes it brutally clear that a being can be deeply sincere and still be on a path that does not arrive. Sincerity is one ingredient among many; the structural fit between path, intention, faculty, and disposition is what determines the destination. Contemporary spirituality, with its heavy emphasis on "authenticity" and "showing up," often obscures this fact.
4. The false belief that all paths are equivalent. Pluralism is a contemporary virtue. The *Yogācārabhūmi*'s distinction between paths that produce 離染, paths that produce 畢竟清淨, and paths that produce only 不畢竟清淨 is a direct refutation of the strong form of pluralism. Not all paths lead to the same destination. This is not a sectarian claim; it is a structural observation about how cause and effect actually operate.
5. The need for teachers who have this diagnostic capacity. The whole point of the Ten Powers is that a Tathāgata teaches each being according to what that being's path actually needs — not according to a one-size-fits-all doctrine. In the absence of a Tathāgata, the best we can do is cultivate teachers and communities that approximate this discernment. The classical exposition is essentially a job description for such teachers.
Common misreadings and clarifications
Misreading 1: "This is the Buddha's power to predict the future." The sixth power is not predictive in the fortune-teller sense. It does not say "you will get a new job in three months." It says "this course of conduct, in this being, with this seed-nature, is structurally tending toward this kind of outcome." It is diagnostic of *trajectory*, not specific event-prediction. Trajectory-knowledge is much more reliable than event-prediction — and far more useful.
Misreading 2: "The Tathāgata's perfect knowledge means everyone will eventually be saved." The *Mahāratnakūṭa* is explicit that 邪定之性 beings — those caught in nets of wrong view with thin consciousness and deep ignorance — cannot be liberated by the Tathāgata's direct teaching in this very life. This is not a defect in the Tathāgata; it is a feature of how seeds and conditions actually work. The Bodhisattva path (which the sutra immediately invokes) is precisely the response to this limit — entering directly into the worlds of such beings to teach them over longer arcs of time. The sixth power teaches us not to expect liberation for everyone, and not to be discouraged by that — there is a longer, slower work.
Misreading 3: "This is the same as the Third Eye or clairvoyance." The Ten Powers are not extrasensory perception in the paranormal sense. They are structural cognitions — ways of seeing how causes produce effects, how seeds ripen into dispositions, how conducts turn into destinations. Clairvoyance would be closer to the third or eighth Tathāgata-power (knowing others' minds or knowing deaths and rebirths). The sixth power is more like a master's understanding of structural engineering than a mystic's vision.
Misreading 4: "Since the Tathāgata knows everything, I should just surrender my own discernment." This is the opposite of what the sixth power implies. The whole point is that the *Tathāgata teaches according to the being's nature* — which means a being's own discernment is part of what is being cultivated. The sixth power in a Tathāgata is matched by, and is in fact the perfection of, the *faculty of wise self-knowledge* in the practitioner. The Tathāgata's perfect seeing and the practitioner's honest self-examination are the same activity at different scales.
Misreading 5: "This is a doctrine of determinism — my path is fixed." The three natures are not fixed essences; they are current seed-conditions. A being of 不定之性 can ripen into liberation or fail to, depending on conditions. A being of 邪定之性 can, over long arcs of Bodhisattva-work, have their seed-conditions transformed. The fourth-power background (the four kinds of seeds, including 可修治種子) explicitly affirms that some seeds are remediable. Determinism is a category the classical texts consistently refuse.
Misreading 6: "Since this is one of the Buddha's powers, it's irrelevant to my life." This is the most subtle and most common misreading. The Ten Powers describe the Tathāgata's cognition, but the *structure* of that cognition — seeing how conducts tend toward outcomes — is something every mature practitioner begins to approximate. When a seasoned practitioner stops blaming themselves for not being saved by a particular technique, when they begin to see *why* certain practices produced only provisional relief, when they can read the trajectory of their own conduct with some honesty — they are cultivating the human-scale version of the sixth power. The Tathāgata's version is unbounded; ours is partial. But the direction is the same.
Misreading 7: "This makes the teacher an elitist who picks favorites." The Tathāgata's different teaching for the three natures is not favoritism; it is accurate dosing. A doctor who gives a different medicine to each patient is not playing favorites. The contemporary spiritual teacher who teaches the same thing to everyone — because they only know one thing, or because they are afraid of offending — is in fact *failing* the sixth power. To teach each being according to that being's nature is the opposite of elitism; it is the very definition of compassionate precision.
Where this leaves us
The sixth Tathāgata-power is, in the end, a teaching about honesty. The Tathāgata sees clearly where each course of conduct is actually going — not where the practitioner hopes it is going, not where the teacher's preferred doctrine says it should go, but where the structural reality of cause, seed, faculty, and conduct is in fact tending. The wisdom of this power is what makes the Buddha's teaching non-abstract: every dharma talk is calibrated, internally, against the actual trajectory of the being who is hearing it.
For a contemporary practitioner, the workable slice of this teaching is not "I should have the Buddha's perfect diagnostic vision." It is something more modest and more demanding: *I should be willing to look honestly at which kind of conduct my own path actually is, and at where that path is actually tending.*
A practice that has produced real relief but no fundamental freedom — is that 不畢竟清淨?
A practice that has produced both insight and entanglement — is that 流轉及不流轉?
A sincerity that has not arrived — is that one of the four 行/修 combinations, and which one?
A being whose path I have been trying to change by force — is that being's nature 不定 (still ripenable) or 邪定 (beyond my reach)?
The classical exposition is not asking us to acquire a supernatural power. It is asking us to develop a human capacity the tradition considers essential: the willingness to see where things are actually going, rather than where we want them to be going. That capacity, when cultivated with honesty over time, is the small-scale version of what the Tathāgata sees without limit — and it is, the tradition insists, sufficient to change the trajectory of one's own liberation, and to teach others in a way that actually reaches them.
That is what the sixth of the Ten Powers is for.
