一、这个概念在说什么
行部 (xíng bù), also written 事行部 (shì xíng bù) — Sanskrit *caryā-tantra*, literally "conduct-tantra" or "performance-tantra" — is the second of the four classes of Buddhist tantra (密續, *guhya-mantra*) as classified in Tibetan Vajrayāna (金剛乘). The principal source for the articulation of these four classes is 《密宗道次第廣論》(*Lam rim chen mo* of the secret vehicle, by Tsongkhapa, drawing heavily on the Indian master Alankarakalasha). The four classes are: 事部 (*kriyā-tantra*), 行部 (*caryā-tantra*), 瑜伽部 (*yoga-tantra*), 無上瑜伽部 (*anuttarayoga-tantra*, "highest yoga tantra"). 行部 sits in the second position — above 事部, below 瑜伽部, well below 無上瑜伽部. This is a staircase of matching, not a ladder of dignity.
1. The defining axis: balanced reliance on external form and internal yoga
The central criterion, given in the original line 「若待外事內定等分非待極多外事，即是行部之機」, is the practitioner's *adhipati* (機, the "vehicle" or "apparatus" — meaning: what supports them, what they need in order to practice). Specifically: how much do they depend on 外事 (external ritual — mandala, offerings, gesture, sacred space) versus 內定 (internal meditation, *yoga*).
The four-tantra staircase, by this criterion, is:
| Class | External ritual (外事) | Internal yoga (內定) | |---|---|---| | 事部 (*kriyā*) | Many, dominant | Present but lesser | | **行部 (*caryā*) | Roughly equal to internal | Roughly equal to external** | | 瑜伽部 (*yoga*) | Little | Dominant | | 無上瑜伽部 | Not needed | Not needed (transcends the axis) |
So 行部 is the *balanced middle*: a practitioner who is genuinely stabilized by an external sacred container — a time, a place, a mandala, a form — and who is *simultaneously* engaged in a comparable weight of interior contemplative work. Form is not yet discardable. Form is balanced by realization.
2. "Using sense-objects as the path" (欲塵為道) — shared premise, different *which*
A foundational premise of all four Vajrayāna classes is 欲塵為道 — using the ordinary objects of the desire-realm (sense experience) *as* the path, rather than fleeing from them. This is conditioned by 空性見 (the view of emptiness) and 天瑜伽 (deity yoga). What differs across the four classes is *which* sense-engagement becomes the transforming path:
- 事部 and 行部 (together): 「除觸塵外，依笑視緣所生喜樂為道，配事行續」 — "Setting aside tactile objects, the joy arising from laughter and gazing is used as the path, matched with the action-class tantras." - 瑜伽部: the tactile (*spraṣṭavya*) of 執手、抱持 — taking hands, embracing. - 無上瑜伽部: 二根交合 — sexual union.
This is a *technical* assignment of which sense-modality, in which class, serves as the central transformative engagement. Laughter and gaze are not a euphemism for anything; they are a specific diagnosis of how, at this level of practitioner, the radiance of being-with-a-deity-form becomes the path. (In actual tantric practice, the "deity" and the "consort" are ritually and contemplatively framed — they are not a license for unskillful behavior in ordinary life.)
3. The 痴 affinity — "delusion-predominant, faith-endowed"
The same Indian master, Alankarakalasha, matched the four tantras with the four principal 煩惱 (*kleśa*, afflictions). For 行部: 「於貪瞋薄愚痴增上，勝解徧入天者宣說行部」 — "For those whose lust and aversion are slight but whose delusion/confusion (痴) is predominant, and who have resolute, penetrative faith in the deity (勝解徧入天者), 行部 is taught."
This is worth pausing on, because every term is doing work:
- 痴 (*moha*, delusion) here is not stupidity, not a moral failing, not a permanent trait. It is a *predominant tendency of mind in this lifetime*: thick, scattered, low-grade bewildered, dispersed — not the sharp burning of 貪 (lust/attachment) and not the sharp edge of 瞋 (aversion/anger), but a kind of fog, an inability to land the mind clearly on anything for long. In modern English: the chronically distracted, the mildly checked-out, the person who knows they should be doing something but cannot quite gather themselves to do it. - 勝解徧入天 is the counterweight that makes this a 行部, not a degenerate, prescription. 痴 is not sufficient — the apparatus must also have a *deep, stable, confident faith-orientation toward the deity*. The 行部 practitioner is confused and devout. The form, the deity, the sacred object is precisely what they need to lean into, *because* their internal container is weak.
This pairing is diagnostic and skillful, not pejorative.
4. The four-stage path (道次第)
According to 《密宗道次第廣論》, 行部's path has four stages:
1. **灌頂 (*abhiṣeka*, initiation):** Establishing the practitioner as a fit vessel. The principal mandala used is the 大悲藏 (Great Compassion Treasury) mandala from 《大日經》(*Vairocanābhisambodhi-tantra*, the "Tantra of Vairocana's Actualization of Enlightenment," commonly called the *Mahāvairocana Sūtra*). 2. 淨三昧耶及律儀 (purification of samaya and vows): Purifying the tantric commitments (*samaya*) and receiving bodhisattva vows, on the basis of 《大日經》、《文殊根本經》(*Mañjuśrī-mūla-tantra*), and 《菩薩地善巧方便經》. 3. 住三昧耶承事 (service while maintaining samaya): This stage subdivides into: - 分別瑜伽 — "analytical yoga," the structural exposition. - The exposition of meaning, which contains: - 有相瑜伽 — "yoga with form": deity mantra recitation *without* simultaneous explicit cultivation of the emptiness-view. - 無相瑜伽 — "formless yoga": deity mantra recitation *combined with* the emptiness-view. This is a precise technical feature: 行部 contains *both* with-form and formless mantra-recitation, indicating the integration of form and realization that is the class's signature. 4. 修成就 (accomplishment): The ripening of the practice.
5. The "self-generation as deity" (自起為天) controversy
A running technical debate in the Indian-Tibetan commentarial tradition is whether 行部 includes 自起為天 (*ātmamāyā*, self-generation as deity — visualizing oneself *as* the deity rather than generating the deity externally). Some Tibetan masters held that 行部 has no self-generation; others held that *both* 事部 and 行部 lack it. Buddhaguhya (佛密) and Jñānapāda (勝菩提) reportedly held that 事部 *does* have self-generation.
The author of 《密宗道次第廣論》 — citing the 行部 root tantras 《大日經》 and 《金剛手灌頂經》 (*Vajrapāṇi-abhiṣeka-tantra*) — judges otherwise: 「計行部無自起天，不應道理」 — "To hold that 行部 lacks self-generation-as-deity is not reasonable." 《攝行論》(*Caryā-saṃgraha*) likewise identifies 《大日經》 as a 行部 root tantra.
The point is non-trivial: 行部 is not "external-only ritual." It contains internal deity-yoga as a core feature, balanced with external form. To read it as ritual-without-internal-contemplation is to read the staircase backward.
6. Scriptural foundations and terminology
- 行部's primary tantras: 《大日經》, 《金剛手灌頂經》. - 事部's primary tantras: 《攝真實會》(*Sarva-tathāgata-tattvasaṃgraha*), 《集智金剛續》, 《後靜慮經》, 《蘇悉地經》, 《妙臂問經》(*Subāhuparipṛcchā*). - 行部 and 事部 are routinely paired as 事行兩部, share the four-branch recitation meditation (四支念誦靜慮), and together constitute the opening chapter of the distinctive Vajrayāna path-stages (事行部道次第). - The class name 行部 / 事行部 / *caryā-tantra* is used interchangeably in the sources.
二、生活里的走查
行部 is a precise technical tantric classification. It is not a meditation practice a layperson casually "does" — it requires empowerment, lineage transmission, a specific ritual container. What *can* be walked through in everyday life is the logic of the classification: the principle that the right practice is the one that matches the apparatus, and that for the delusion-predominant, faith-endowed apparatus the prescription is *balanced form and interior depth*. The point is not to make the reader a tantric practitioner. The point is to show that this classical diagnosis illuminates a very contemporary problem: the split between *form-without-depth* and *depth-without-form*, and the special difficulty of the *foggy, scattered mind*.
Scene 1 — The meditator who can't sit
A contemporary practitioner decides to "just meditate." No shrine, no candles, no ritual, no schedule. Just sit. Within three minutes, the phone is in the hand. The mind is a soup of half-remembered tasks, vague anxiety, and unrelated snippets. They will conclude, after a few months of this, that they "can't meditate."
Mapped onto the classical diagnosis: their internal contemplative capacity (內定) is weak; their mind is dispersed in the mode of 痴 (not sharp desire, not sharp aversion, but thick bewilderment); and they are operating with no external container at all. By the staircase criterion, this is *below* 行部 — they are skipping form entirely. They may even imagine they are attempting 瑜伽部's "internal, form-light" mode. The system would say their apparatus cannot sustain that mode without some balancing external support.
Where they mis-map: they assume *less form* = *more spiritual*. The 行部 diagnosis says the opposite for this apparatus: **they need a balanced external container precisely *because* the internal one is too weak to hold itself.** Strip form away and the practice dissolves into the existing dispersion.
Scene 2 — The elaborately ritualized practitioner who is hollow inside
The contemporary spirituality market is full of people who have built elaborate external containers — altars, candles, crystals, sage bundles, intricate morning routines, twelve-step structures, astrology charts — but whose interior contemplative life is thin or absent. They do the form with great precision and feel nothing. Or they feel the form ritualistically but never bring the practice into unmediated moments.
Mapped onto the criterion: this is over-investment in 外事 without matching 內定. By the staircase, this is closer to 事部 without the 行部 balance. The form becomes aesthetic, social, performative — a kind of spiritual consumerism.
Where they mis-map: they assume the *thickness of the form* = *the depth of the practice*. 行部 would say: form and inner realization should ride together. If only one is present, the practice is structurally incomplete.
Scene 3 — The "delusion-predominant" contemporary, and why 行部's prescription fits
The 行部 practitioner, classically, is the one whose 貪 and 瞋 are relatively light but whose 痴 is heavy. In modern life this is recognizable as a *type*: not the driven pleasure-seeker (貪 增上), not the chronically resentful (瞋 增上), but the *foggy, scattered, mildly depressed, can't-quite-focus, checked-out* person. The one who knows they should meditate, exercise, eat well, call their mother — and doesn't, not out of rebellion or indulgence but out of low-grade bewilderment and inertia. The one scrolling a feed at 11 p.m. who has consumed thirty pieces of content and cannot remember any of them, who feels vaguely anxious but cannot locate the cause.
For such a person, the 行部 prescription makes immediate classical sense. They are not helped by being told to "let go into formless awareness" — they will lose the thread in three seconds. They are also not helped by being told to "build a perfect altar" — they will build it and forget to use it. What they need is a balanced container: a set time, a set place, a set form (even a small one), joined with a small, sustainable interior practice of equal weight. A daily liturgy. A morning mantra with a candle. A weekly half-hour of seated practice with a clock and a bell. The form *holds* the inner practice; the inner practice *gives the form life*.
The classical line is worth quoting again: 「於貪瞋薄愚痴增上，勝解徧入天者宣說行部」. The 行部 prescription is not for the confused-but-disengaged. It is for the confused who have a stable, penetrative devotion — a trusted form, a sacred object, a name or image to lean toward. The form is precisely the antidote to the dispersion.
Scene 4 — The "smiling and gazing" of ordinary life
The classical description of 行部 (paired with 事部) — 「除觸塵外，依笑視緣所生喜樂為道」 — using the joy arising from laughter and gazing as the path, is not, emphatically, a license for any kind of behavior. It is a description of how, in tantric practice, the radiance and warmth of being-present-with-a-deity-form becomes itself the contemplative support. In ordinary life, this structure shows up in unexpected places: the moment of shared laughter that cracks the routine; the gaze with a child, a partner, a friend, an elderly relative, that holds without grasping; the half-second of mutual seeing across a noisy room where something transparent flashes through. These are not, by themselves, the path — but they are *cracks in ordinary solidity* where joy becomes briefly unobstructed.
Where people mis-map this most damagingly: by assuming that any laughter-and-gaze situation is "tantric" or "spiritual" — that spontaneity of feeling is itself the practice. It is not. The classical system is precise: laughter and gaze are the path *within a container of vow, view, and long preparation*. In ordinary life the lesson is more modest — such moments are worth *noticing*, *not narrating away*, *not destroying* — but they are not, by themselves, realization. They can *point to* realization; they cannot replace it.
三、当代人为什么需要它
The contemporary mind is, on the average across many populations, more 痴-predominant than previous centuries made it. The classical 貪 (acute single-pointed desire) and 瞋 (acute reactive anger) are not absent, but alongside them there is an epidemic of dispersion — of attention fragmented across many small channels, of low-grade bewilderment that is neither hot desire nor sharp rage but a kind of permanent drift. The default-mode-network-dominant state of scrolling, partial-attention, half-finished thought is, neuro-phenomenologically, a plausible contemporary correlate of the classical 痴. *Plausible* — not identical. The classical category is not a neuroscientific claim; the brain does not map cleanly onto Buddhist categories; some studies suggest contemplative training modulates DMN activity, but that is a partial and unfinished parallel at best, and the classical diagnosis stands on its own internal logic, which we should not pretend neuroscience has confirmed.
For such a person, two contemporary failure modes are common:
- Formless spirituality without container. The reading-and-listening-and-discussing-and-meditating-for-thirty-seconds lifestyle. It feels progressive, anti-institutional, "advanced." By the 行部 criterion, it is a mismatch: the apparatus cannot yet sustain this without some external structure, and so the practice dissolves into the very dispersion it was meant to address. - Container without interior. The elaborate altar, the perfect morning routine, the aestheticized discipline — without a parallel interior deepening. By the 行部 criterion, this is also a mismatch: the form is not yet animated by an equal interior weight, and so it remains aesthetic or superstitious rather than transformative.
行部's principle — balanced form and depth, matched to the apparatus — is precisely what is missing from both failure modes. The prescription is not "less spiritual" than the formless path; it is not "more disciplined" than the form-only path. It is *accurate to the apparatus*.
Practically, the 行部 principle can be taken up in everyday life — not as tantric practice, but as a diagnostic lens — in a few simple moves:
1. Notice the apparatus. Are you more 貪, 瞋, or 痴 predominant in this lifetime? Do you have a stable, faith-endowed orientation toward *something* (a tradition, a teacher, a text, a practice, a vow) — or are you floating between options without anchor? 2. Match the practice to the apparatus. If you are 痴-predominant and faith-endowed, *add* form. A small, fixed, repeated, externally-anchored practice. Not more discipline in the abstract; a specific form at a specific time at a specific place. 3. Balance it with a small interior practice of equal weight. Not bigger, not smaller. The classical 有相/無相 pairing of mantra-recitation indicates that the form *and* the interior-view are to ride together, even at modest scale. 4. Notice the 笑視 moments without claiming them. The shared laughter, the gaze that holds — these are signals, not substitutes. They tell you the form-and-interior balance is doing something. They are not, by themselves, the path. 5. Let form and interior evolve together. The staircase is real — over time, the apparatus may shift, and a practitioner who needed lots of form may eventually need very little. That is a long, organic process, not a jump to be made by willpower.
The point is not to imitate a tantric system without empowerment. The point is to take seriously that there is a classical diagnosis of which vehicle fits which apparatus, and that the "balanced form-and-depth" prescription has been carefully articulated for the *delusion-predominant, faith-endowed* practitioner — which is many of us, today, and which the popular spirituality market rarely addresses directly.
四、常见误读与澄清
Misreading 1: "行部 is the tantric sex class." This is the most pervasive contemporary confusion, fed by a popular culture that equates "tantra" with sexuality. It is wrong, on both the line and the direction. Sexual union (二根交合) is explicitly assigned to 無上瑜伽部 — the *highest* class, not 行部. 行部 and 事部 together are matched with laughter and gaze, *not* touch, *not* union. This is not squeamishness; it is a precise technical assignment of which sense-modality, in which class, is the transforming path. To read 行部 as "the sexual tantra" is to reverse the staircase.
Misreading 2: "行部 is the 'lower' tantra, less advanced, for beginners." This conflates position in the staircase with spiritual inferiority. The four classes are not ranked by depth of realization but by *capacity of apparatus*. 事部 and 行部 are not lesser paths; they are *precisely-matched* paths for a particular apparatus. To place a 行部 practitioner into 無上瑜伽部 practice is not an upgrade; it is a mismatch that the tradition regards as dangerous to the apparatus and to the vows. The system is *calibration*, not hierarchy-of-dignity.
Misreading 3: "行部 is mostly external ritual — not really internal tantra." This is exactly the misreading that the 《密宗道次第廣論》 author is correcting in the 自起為天 controversy. Some Tibetan masters held that 行部 has no internal deity-yoga; the author disagrees, on the textual grounds of 《大日經》 and 《金剛手灌頂經》: 「計行部無自起天，不應道理」. So the *balance* of form and internal yoga is built into the class. To reduce it to external-only ritual is to misread the system.
Misreading 4: "The 痴 affinity means 行部 is for stupid or 'deluded' people — an insult." The 痴 here is not stupidity, not a moral failing, not a permanent trait. It is a *predominant tendency of mind in this lifetime* — heavy dispersion, thick bewilderment — *paired with a stable, penetrative devotional orientation* (勝解徧入天). Many serious contemplatives recognize themselves in this description. The category is diagnostic and skillful-means, not pejorative.
Misreading 5: "If I'm modern and post-traditional, I should do formless meditation, not ritual." This is a popular contemporary assumption that the 行部 criterion directly challenges. The criterion says: if your internal apparatus is weak and you lack a balancing external container, the formless approach will not lift you — it will dissolve into your existing dispersion. The prescription is not "do more" or "do less"; it is "do what matches the apparatus." For many contemporary minds, that means more form, not less, in order to support an interior that cannot yet self-sustain.
Misreading 6: "The four-tantra staircase is just a historical Tibetan artifact with no contemporary relevance." The categories can be treated as historical taxonomy — and then they are museum pieces. Or they can be used as a diagnostic instrument: *what is my apparatus, what is my affliction-pattern, what kind of container do I actually need, and what kind of container do I currently mistake for depth?* Used in the second way, they remain sharp. The danger is treating them as either magical (a label to claim) or merely academic (a curiosity to footnote).
Misreading 7: "The balanced-form prescription is just a matter of personal preference." It is not preference; it is *diagnosis of apparatus*. Someone who is sharp, focused, internally strong, and devotionally stable may genuinely need little external form and may be a proper 瑜伽部 candidate. Someone who is scattered and devotionally lean may need much more form and may be a proper 事部 candidate. Someone for whom 貪 or 瞋 is acute may need a different engagement entirely. The 行部 prescription is for a specific apparatus. The contemporary trap is taking what fits *one* apparatus as universal — particularly the formless prescription, which is currently fashionable and is, for many actual apparatuses, the wrong fit.
