What this concept is saying

Imagine three people asking where the Buddha is.

One points to Śākyamuni walking between villages, teaching particular people in words they can understand. Another thinks of the majestic Buddha encountered by advanced bodhisattvas in a pure realm, inseparable from inexhaustible wisdom and Dharma-bliss. A third asks what makes either appearance possible at all—what remains when “Buddha” is no longer confined to a body, a place, an image, or even a concept.

The doctrine of the Three Bodies—三身 (sānshēn; Sanskrit: trikāya)—answers all three questions together. They are:

- 法身 (fǎshēn; Dharma-body or dharmakāya): the fundamental reality and perfected freedom upon which all Buddha qualities and manifestations depend.

- 報身 (bàoshēn; reward-body or enjoyment-body, 受用身 shòuyòngshēn): Buddhahood as the consummate enjoyment and communication of wisdom, merit, pure realm, and Dharma-bliss, especially in relation to bodhisattvas.

- 化身 (huàshēn; transformation-body or nirmāṇakāya, also 變化身 biànhuàshēn): the many forms in which a Buddha appears according to beings’ capacities, circumstances, conduct, and needs.

This is not a Buddhist theory of three separate supernatural persons. Nor is it merely a classification of three kinds of statues or visionary experiences. It is a way of describing perfected awakening from three inseparable angles: its truth, its fulfilled wisdom, and its compassionate activity.

A compact way to remember the relationship is:

Dharma-body is awakening as reality and freedom; enjoyment-body is awakening fully possessed and shared as wisdom; transformation-body is awakening made accessible in the conditions of a particular life.

That formula is only an entry point. Each body needs to be understood on its own terms.

1. Dharma-body: not a cosmic physical body

The Dharma-body is the root of the other two. The *Suvarṇaprabhāsottama-sūtra*—《金光明最勝王經》—calls the first two bodies provisionally existent by designation and the Dharma-body genuinely real, “the foundation of the first two.” It identifies its content as 如如 (rúrú; suchness) and 如如智 (rúrú zhì; wisdom of suchness). It is beyond all determinate marks, is not an object that grasping can seize, and is therefore said to be neither one nor two.

“Body” here does not mean a shape occupying space. It carries the sense of a basis, an integrated reality, or that upon which qualities depend. Paramārtha’s translation of the *Mahāyānasaṃgraha-bhāṣya*—《攝大乘論釋》—accordingly calls it 自性身 (zìxìngshēn; intrinsic or essential body): the support of the enjoyment and transformation bodies and of all a Buddha’s qualities.

Nor should “truly existent” in the *Golden Light Sutra* be hurriedly turned into the claim that the Dharma-body is an eternal metaphysical self. The same description says that it transcends graspable characteristics, has no dependent locus, and is neither one nor two. Its permanence means that it is not a conditioned product that comes into existence, alters, and perishes. It does not mean an immortal personality hidden inside impermanent beings.

The text joins suchness and the wisdom of suchness without collapsing them. Suchness points to reality free of delusive fabrication; the wisdom of suchness is awakening’s unobstructed realization of it. The sutra says that they are “neither one nor different.” It also describes self-benefit through suchness and benefit to others through the wisdom of suchness. Even at the most fundamental level, therefore, Buddhahood is not a private retreat into an inert absolute. Its freedom and its knowing compassion cannot finally be torn apart.

In the language of the *Mahāyānasaṃgraha-bhāṣya*, the Dharma-body is 斷德 (duàndé; the virtue of relinquishment): the perfection revealed through the complete ending of obscurations. This is why it is associated with self-benefit—not selfish benefit, but the consummation of liberation itself. The same commentary warns that it is difficult to “see”: ordinary beings, śrāvakas, pratyekabuddhas, and beginning bodhisattvas do not apprehend it as profound bodhisattvas and Buddhas do. It is not an item delivered to the ordinary senses.

2. Reward-body or enjoyment-body: awakening in its fulfilled splendor

The reward-body, more precisely called the enjoyment-body, is Buddhahood as the fulfilled “fruit” of immeasurable merit and wisdom. According to the *Mahāyānasaṃgraha-bhāṣya*, the Buddha, relying upon the intrinsic body, completes the two courses of merit and wisdom; the resulting pure land and great Dharma-bliss are enjoyed by the Buddha, hence the name “enjoyment-body.” It also enables advanced bodhisattvas to share in Dharma-bliss and to complete the resources of awakening.

“Reward” can sound like a prize handed out by a cosmic authority. That is misleading. The term points to fruition: wisdom and compassionate cultivation have become completely mature. Just as fluency is the embodied fruition of long learning—though infinitely more profound here—the enjoyment-body is awakened cultivation come to perfect fulfillment. Its splendor is not spiritual decoration added to awakening. It expresses the inexhaustible merit and wisdom of Buddhahood.

The *Golden Light Sutra* uses the name 應身 (yìngshēn; responsive body) where many later summaries would expect “reward-body.” In that sutra, this body appears through suchness, the wisdom of suchness, and the power of original vows. It teaches ultimate truth for bodhisattvas’ penetration, enables them to understand the single flavor of saṃsāra and nirvāṇa, and appears with the thirty-two marks, eighty excellent characteristics, and radiant halo.

Terminology must therefore be handled with care. “Enjoyment-body,” “reward-body,” and “responsive body” overlap in the materials provided, and Paramārtha’s commentary itself employs paired terminological schemes. But 應身 is not a universally fixed synonym for 報身 in every Buddhist text or scholastic system. Some traditions use “responsive body” in ways closer to manifestation. The names should be read within the classification of the particular source, not mechanically exchanged across all sources.

The enjoyment-body is 智德 (zhìdé; the virtue of wisdom) in the commentary’s threefold division. It is also a body for benefiting others: awakened wisdom becomes communicable without being reduced to the limitations of an ordinary teacher’s personality. Its audience and mode differ from those of the transformation-body. The latter adapts into diverse forms for diverse beings; the enjoyment-body presents the unified majesty of awakening to bodhisattvas capable of receiving profound Dharma.

3. Transformation-body: compassion taking a form that can be met

The transformation-body is not just “the Buddha’s human body,” though the historical appearance of Śākyamuni is its paradigmatic example. Its definition is much broader. The *Golden Light Sutra* says that a Buddha understands beings’ intentions, conduct, dispositions, places, times, and appropriate teachings, and consequently manifests many kinds of bodies. Paramārtha’s commentary says that, through the sovereign power of original vows, a Buddha appears in ways that vary according to beings’ consciousness and their stages of practice.

Thus the defining principle is not mere physicality but adaptive manifestation. A transformation-body is awakening meeting beings within conditions they can actually encounter. Because beings’ minds and circumstances are many, its forms are many.

The sutra makes a subtle claim about its permanence. The transformation-body is “constant” insofar as the turning of the Dharma wheel and compassionate responsiveness continue wherever conditions call for them. Yet it is “impermanent” insofar as a particular manifestation is not the fundamental body and does not display the whole of a Buddha’s function. Śākyamuni’s birth and passing are therefore not evidence that Buddhahood itself began and ended between two dates. The appearance is conditioned and finite; the compassionate activity it expresses is not exhausted by that appearance.

In the three virtues, transformation-body is 恩德 (ēndé; the virtue of beneficence or compassionate grace). This does not mean condescending charity. It is wisdom becoming concrete enough to guide someone: a teaching in an intelligible language, a discipline suited to a particular weakness, an example that can be imitated, or a presence that restores the possibility of practice.

A useful analogy is responsive design. The underlying content of a service may be one, but it appears differently on a phone, a desktop, or through assistive technology because users’ conditions differ. Yet a Buddha is not an algorithm optimizing engagement, and beings are not merely devices receiving formatted output. Algorithms infer from limited data, reproduce biases, and pursue objectives assigned to them. Buddhist compassionate responsiveness is presented as grounded in perfected wisdom, vows, and freedom from self-interest. The analogy illuminates adaptation; it does not establish equivalence.

4. Three without separation, one without erasing difference

The three bodies form an intelligible dependence:

- The Dharma-body is the basis of awakened qualities and of the other two bodies.

- Relying on that basis, the enjoyment-body expresses the complete fruition of merit and wisdom and communicates Dharma-bliss to advanced bodhisattvas.

- Relying upon awakened wisdom, vows, and the enjoyment-body, transformation-bodies appear in diverse forms for beings in diverse conditions.

But this should not be imagined as a production line in which one entity manufactures a second, which later manufactures a third. Tiantai teaching describes the three as 不縱不橫 (bù zòng bù héng)—neither vertically successive nor horizontally separate. The *Profound Meaning of the Lotus Sutra*—《妙法蓮華經玄義》—says, “三軌名異,義即三身”: the “three tracks” differ in name but are in meaning the Three Bodies. Its point is their mutual inclusion and non-fragmentation.

Chan texts sharpen this by saying “三身一體,一體三身”: “Three bodies, one integral reality; one integral reality, three bodies.” When someone asks which body is the original body, a recorded answer is “闕一不可”—“Not one can be lacking.” The Dharma-body is fundamental, but a “Dharma-body” severed from wisdom and compassionate responsiveness would be a frozen abstraction devised by thought, not living Buddhahood. Conversely, manifestations without truth and liberating wisdom would be ordinary conditioned appearances.

This is also why some Chan sayings declare that reward and transformation bodies are “not the true Buddha,” because they arise dependently, while other encounters refuse even to let the student fix the Dharma-body as the “true Buddha.” These statements operate at different moments of instruction. The first breaks attachment to appearances; the second breaks attachment to an imagined formless absolute. If one turns “Dharma-body” into a final object and then asks where it speaks from, Chan teachers expose the conceptual trap. The teaching is medicine, not a new substance to grasp.

5. The Three Bodies within the path of liberation

The doctrine is a description of the Buddhist goal, but it also tells us what the path must cultivate. Liberation is not complete if it is imagined as merely escaping private distress.

The *Mahāyānasaṃgraha* places attainment of the purified Three Bodies at the culmination of the bodhisattva path: through 無分別智 (wúfēnbié zhì; nonconceptual wisdom), bodhisattvas reach the ultimate stage and attain supreme mastery. Its commentary relates the three fruits to realization through the ten bodhisattva grounds: penetrating the basis of nonconceptual wisdom culminates in the Dharma-body; mastery concerning pure land and wisdom culminates in the responsive or enjoyment-body; mastery of liberative activity culminates in the transformation-body. All three rely upon suchness.

This gives the path a threefold completeness:

- Delusion and obscuration must actually end. Otherwise there is no Dharma-body as perfected relinquishment.

- Wisdom and merit must mature positively. Otherwise liberation is described only as absence, not as inexhaustible awakened capacity.

- Compassion must become skillful activity among beings. Otherwise wisdom remains, in our imagination, sealed away from the suffering world.

The Three Bodies therefore prevent three distortions of liberation: treating it as personal annihilation, treating it as private mystical enjoyment, or treating compassionate work as sufficient without uprooting ignorance. The bodhisattva path joins release, realization, and response.

The *Platform Sutra of the Sixth Patriarch*—《六祖大師法寶壇經》—brings this vast fruit-language into immediate practice through a distinctive Chan interpretation: “清淨法身汝之性也,圓滿報身汝之智也,千百億化身汝之行也”—“The pure Dharma-body is your nature; the perfect reward-body is your wisdom; the hundreds of thousands of millions of transformation-bodies are your conduct.” It calls this 一體三身自性佛, the “self-nature Buddha of one essence and three bodies,” and says the Three Bodies arise from self-nature, not from something acquired outside.

This must not be flattened into “I am already a Buddha, so nothing needs doing.” In that same interpretive frame, nature, wisdom, and conduct are inseparable. Claiming pure nature while remaining governed by greed, hostility, and self-deception is merely adopting a noble label. Likewise, outwardly helpful conduct without wisdom can become compulsive rescuing, control, or moral vanity. “Not obtained from outside” removes alienation from awakening; it does not remove the work of seeing through delusion and embodying wisdom.

A walk-through in everyday life

Consider an evening commute after a difficult day. Your manager has sent a short message: “We need to talk tomorrow.” On the train, you open your phone repeatedly, reread the sentence, imagine being dismissed, compose defensive replies, and then notice that you have become cold toward your partner, who has asked an innocent question.

The Three Bodies are Buddha-fruit, not three ordinary psychological modules. So we must not say that your awareness literally “is the Dharma-body,” your pleasant emotion “is the reward-body,” or your text reply “is the transformation-body.” That would reduce a doctrine of perfect awakening to a self-help diagram. But the threefold structure can guide a careful examination of what practice is moving toward.

Step one: look for what is true rather than what fear has fabricated.

The message contains a few words. Your mind has supplied dismissal, humiliation, financial disaster, and anticipated conflict. Practice begins by distinguishing what is present from what grasping has constructed. Sensations tighten in the chest; anxious thoughts arise; possible futures are imagined. All are dependently arisen events, not a permanent self and not yet tomorrow’s reality.

This is a faint, path-level orientation toward what the Dharma-body signifies at fruition: freedom from distortion and direct realization of suchness. It is not yet the Dharma-body itself. The common mapping error is to call any bare or calm awareness “the Dharma-body.” A temporary mindful state remains conditioned and can be interrupted. Dharma-body, in the classical account, is the perfected basis in which the obscurations have been brought to their end; it is beyond graspable marks and is not merely the neutral background of your present experience.

Step two: let clarity become understanding, not blankness.

Having paused, you examine causes and possibilities. The manager may want to discuss performance, a new assignment, restructuring, or something else. You remember your own unfinished work without converting one mistake into a total identity. You see how anxiety tries to secure certainty by rehearsing catastrophe. You also recognize your partner as a person, not as an obstacle arriving at the wrong moment.

This offers an everyday analogy for the wisdom dimension brought to fulfillment in the enjoyment-body. Wisdom is not the pleasure of feeling calm, nor is “reward-body” the emotional reward you receive for meditating correctly. Classical 受用身 concerns the Buddha’s consummate fruition of merit and wisdom, pure realm, and Dharma-bliss, with a revelatory function for bodhisattvas. Your small moment of lucid understanding is practice in its direction, not the body itself.

Step three: respond in a form suited to the actual conditions.

Perhaps you reply to the manager: “Understood. Is there anything you’d like me to prepare?” You tell your partner, “I’m anxious about a work message and noticed I was shutting you out. Give me ten minutes to settle, then I want to hear what you were saying.” Tomorrow, you listen before defending yourself. If criticism is justified, you accept a concrete repair; if it is unfair, you answer firmly without humiliation or retaliation.

This illustrates the principle of adaptive compassionate activity associated with transformation-body. Different people and moments call for different expressions: silence, explanation, apology, a boundary, a question, or practical help. The common error is to equate transformation-body with any outward action whatsoever. Classical 化身 is not simply “behavior.” It is a Buddha’s manifestation through vows and mastery, precisely attuned to beings’ dispositions, conduct, place, time, and needs. An impulsive angry email is also an action, but it is not thereby a transformation-body.

Nor does skillful means mean manipulating people “for their own good.” A response shaped by fear, vanity, or the desire to control may be tactically clever while remaining unliberating. In the doctrine, transformation is rooted in the Dharma-body and fulfilled wisdom. Adaptation without truth becomes expediency; truth without adaptation becomes inaccessible.

Step four: examine whether the three dimensions remain connected.

Suppose you become calm but ignore your partner’s hurt. That resembles an attempt to keep truth private and omit compassionate manifestation. Suppose you say all the correct empathic words but secretly refuse to acknowledge your work error. That is polished manifestation without truth. Suppose you understand the situation accurately but use that understanding to defeat everyone in argument. That is intelligence without liberating beneficence.

The doctrine asks whether freedom from distortion, lucid understanding, and compassionate responsiveness support one another. At the Buddha’s fruition they are inseparable; on the path, their repeated separation shows us where cultivation is incomplete.

The same walk-through applies elsewhere:

- While scrolling, first discern the difference between the actual post and the identity-story or outrage supplied by the mind; then understand the craving and algorithmic reinforcement involved; finally choose an appropriate response—continue, verify, disengage, or speak constructively.

- In parenting, see the child and the present behavior without fixing them as “a difficult child”; understand developmental capacity and your own fatigue; then respond in a form the child can receive, perhaps comfort, a clear boundary, explanation, or quiet presence.

- During overwork, see conditions without turning productivity into a permanent self; understand both responsibilities and bodily limits; then embody that understanding through a conversation, reprioritization, rest, or principled refusal.

Again, these are analogical rehearsals of the doctrine’s architecture. They are not claims that ordinary cognitive processes are literally the Buddha’s Three Bodies. Neuroscience can investigate attention, prediction, emotion regulation, and flexible behavior, but it has no settled experimental measure for dharmakāya or Buddhahood. Scientific models can clarify limited mechanisms of experience; they neither prove nor disprove the soteriological claims of the Three Bodies.

Why contemporary people need it

Contemporary life repeatedly splits what the Three Bodies hold together.

We separate truth from communication. Someone may possess correct information yet express it in a way no one can receive. Online exchanges reward declarations of correctness more readily than patient adaptation to another person’s capacities. The transformation-body reminds us that truth which cannot yet meet a being’s conditions has not completed the work of compassion.

We separate inner cultivation from public conduct. A person may value meditation while treating colleagues, family members, or service workers carelessly. The Three Bodies do not permit awakened reality to remain a private mood. In the *Platform Sutra’s* language, nature flowers as wisdom and wisdom takes shape as conduct.

We also separate activism from freedom of mind. Urgent action is necessary in the face of suffering, but action fueled entirely by hatred, panic, or identity fixation easily reproduces the structures it opposes. The Dharma-body dimension asks whether ignorance is being uprooted; the enjoyment-body dimension asks whether insight and virtue are maturing; the transformation-body dimension asks whether they actually benefit beings.

The doctrine also answers a widespread anxiety about impermanence: if the historical Buddha died, is Buddhism simply the memory of a vanished teacher? The Three Bodies distinguish a finite manifestation from the reality, wisdom, vows, and compassionate function expressed through it. This does not deny the historical Buddha’s embodied life or make his death unreal. It shows why the Dharma is not confined to the biological continuation of one body.

It further protects spiritual life from two opposite fantasies. The first is crude anthropomorphism: imagining the ultimate Buddha as an enormously powerful person somewhere in the universe. The second is sterile abstraction: reducing Buddha to an impersonal principle with no capacity to teach, liberate, or respond. Dharma-body prevents confinement to a person; enjoyment- and transformation-bodies prevent ultimate reality from becoming lifeless.

There is also a lesson for an algorithm-shaped world. Digital systems continually personalize what appears before us, but personalization is not necessarily compassion. It may simply maximize attention, consumption, or predictability. The transformation-body invites a harder question: adaptation toward what end? In Buddhist terms, a response is skillful when it conduces to release from greed, hatred, and delusion—not merely when it secures engagement. Yet human judgment about such outcomes remains fallible, and invoking “skillful means” cannot exempt anyone from accountability.

Most importantly, the doctrine enlarges our idea of liberation. To be free is not merely to become less emotionally uncomfortable. Perfect awakening is presented as the ending of obscuration, the fulfillment of wisdom and merit, and inexhaustible responsiveness to others. The horizon of practice is at once more inward and more relational than wellness culture usually allows.

Common misunderstandings and clarifications

“The Three Bodies are three Buddhas.”

Not in the sense of three independently existing divine persons. They distinguish inseparable dimensions or modes of complete Buddhahood. “Three bodies, one integral reality; one integral reality, three bodies” guards against dividing them, while “not one can be lacking” guards against reducing all three to an empty synonym.

“Dharma-body means the Buddha’s physical body made holy.”

No. A physical body is not the meaning of 法身 here. Dharma-body is suchness and the wisdom of suchness, the unconditioned root and support of Buddha qualities and the other bodies. It exceeds determinate form and ordinary sensory apprehension.

“Dharma-body is a universal soul or true self.”

That conclusion is not warranted by these definitions. The Dharma-body is described precisely as beyond grasped characteristics, neither one nor two, without a dependent locus, and not a conditioned process. To reify it as an everlasting personal essence would restore the kind of fixation the language is meant to undo.

“Reward-body is the pleasant feeling earned through good karma.”

This seriously narrows the term. The enjoyment-body is the perfected fruition of a Buddha’s merit and wisdom, associated with pure realm, great Dharma-bliss, majestic qualities, and the instruction of advanced bodhisattvas. Ordinary happiness after a good deed is neither its definition nor its scale.

“Responsive body and transformation-body are always the same term.”

Not safely. In the *Golden Light Sutra*, 應身 occupies the middle position normally associated with reward or enjoyment-body, while 化身 is the many-form adaptive manifestation. Other taxonomies may use “responsive body” differently. Terminological equivalence must be established text by text.

“Transformation-body means only Śākyamuni’s historical body.”

Śākyamuni’s worldly appearance is a central example, but the category includes the many forms manifested according to beings’ intentions, practices, dispositions, times, and places. Its definition is adaptive liberative appearance, not merely ordinary human anatomy.

“Any compassionate person is literally a transformation-body of the Buddha.”

This may function as devotional or inspirational language, but it is not the strict classical definition given here. A transformation-body is a Buddha’s manifestation grounded in awakening, original vows, and mastery. Ordinary kindness can participate in or train toward compassionate responsiveness without being equated with perfected Buddha activity.

“Since the Dharma-body is real and the other two are provisional, only the Dharma-body matters.”

That turns a distinction of foundation and manifestation into a rejection of compassionate function. Some Chan texts call reward and transformation bodies “not the true Buddha” to loosen attachment to conditioned appearances. Yet the same Chan literature refuses to let students grasp a separate Dharma-body as the true Buddha and says that none of the Three Bodies can be omitted. The provisional is not therefore useless or unreal like a pure hallucination; it is the way liberating truth becomes available under conditions.

“The three form a ladder: first Dharma-body, then reward-body, then transformation-body.”

There are explanatory relations of basis, fruition, and manifestation, and texts also connect their attainment with the culmination of the bodhisattva grounds. But Tiantai’s “neither vertical nor horizontal” warns against imagining three sealed stages or compartments. At fruition they are mutually implicated: genuine realization has wisdom and activity; genuine Buddha activity is rooted in realization.

“The doctrine says saṃsāra is already nirvāṇa, so suffering requires no response.”

The *Golden Light Sutra’s* middle body teaches bodhisattvas to understand saṃsāra and nirvāṇa as having one flavor. This is not permission to deny conventional suffering. If insight into nonduality produces indifference to suffering, it has been detached from the transformation-body’s beneficent function. Nonduality is meant to remove delusive opposition and grasping, not compassion.

“The Three Bodies are merely later philosophy and have nothing to do with practice.”

They are indeed a developed Mahāyāna framework, but the sources explicitly place them at the culmination of nonconceptual wisdom and the bodhisattva path. Tiantai links the Three Bodies with the three contemplations and forms of patient acceptance; Chan relates them to nature, wisdom, and conduct. Different traditions turn the doctrine into practice differently, but none of these accounts treats it as idle anatomy of a heavenly Buddha.

“If the Three Bodies arise from self-nature, I am already fully awakened.”

The *Platform Sutra* uses the teaching to stop outward searching: the pure Dharma-body is one’s nature, the fulfilled reward-body one’s wisdom, and the innumerable transformation-bodies one’s conduct. But it also says that separating the bodies from wisdom produces “body without wisdom.” Inherent orientation and realized fruition are not interchangeable. The point is to awaken and embody what is not obtained as a foreign possession, not to award the ego a Buddha-title.

At its deepest, the Three Bodies answer a single question: What would awakening be if it were completely true, completely fulfilled, and completely available to others?

As Dharma-body, it is no longer deceived about reality. As enjoyment-body, its wisdom and merit are perfectly mature. As transformation-body, it does not abandon beings to an inaccessible absolute. The three are not rival answers. Together they show why liberation, in the Mahāyāna vision, must be freedom from delusion, fullness of wisdom, and compassionate presence—all the way through.

Canonical EntryAI-generated

一、定义与核心要义

三身(trikāya),又作三种身,指佛陀果位所具之三种功德身相。依各经所载,三身之具体名称与内涵不尽相同,然其核心义理皆指向如来自利利他、究竟圆满之身相建立。于一般常见之分类中,法身为根本真实之身,报身(亦称受用身、应身)为受用法乐之身,化身(亦称变化名、变化身)为随机示现之身。

二、主要阐述

(一)法身

法身于各经中皆被视为三身之根本。《金光明最胜王经》明言:「前二种身,是假名有,此第三身,是真实有,为前二身而作根本」,并以「如如、如如智」为法身之内容,说其「过一切种相,非执相境界,是故说名不一不二」,「无依处故」,「非是行法,无有异相,是根本故,犹如虚空,是故说常」。《摄大乘论释(真谛译)》以「自性身」名之,视其为「应化二身及如来一切功德之所依」,并判之为三德中之「断德」。

《古尊宿语录》以「法身实相佛」标举之,称其「不明不暗」,并以「清净法身毗卢遮那佛」「虚空法身佛」「大圆镜智」「第八识」「第一义空」「玄旨」等并列;又以「佛身无为,不堕诸数」显其不可计量。《摩诃止观》引偈「微妙净法身,具相三十二,用庄严法身」标举此名。

(二)报身(受用身/应身)

《金光明最胜王经》以「应身」名之(此经特用「应身」取代「报身」之名),明其「为诸菩萨得通达故,说于真谛,为令解了生死涅槃是一味故」,具三十二相、八十种好、项背圆光,「如如、如如智本愿力故,是身得现」,「弟子一意故现一相,是故说一」,「从无始来相续不断,一切诸佛不共之法能摄持故,众生无尽,用亦无尽」故说为常。《摄大乘论释》并用「受用身」与「应身」二名,指如来「依自性身而起福德、智慧二行,其所得净土清净与大法乐,由佛受用,故名受用身」。

(三)化身(变化身)

《金光明最胜王经》称化身乃如来昔在修行地中由修行力得大自在,随众生意、行、界悉皆了别而现种种身;「第一身依于应身得显现故」;化身「恒转法轮,处处随缘,方便相续,不断绝故」故说常,「非是本故,具足大用不显现故」说为无常。《摄大乘论释》以「变化身」名之,谓佛「依本愿自在力,于他修行地中随众生识而变异显现」。

(四)三身之成立与获得

《摄大乘论本》以「诸菩萨究竟,得清净三身,是无分别智,得最上自在」明菩萨至究竟位由无分别智得三身;又以「不坚业坚业,诸佛具三身」说由坚固之业而具足三身;并明佛身「于一切身现,非六根所行」,「诸佛身常故」。《摄大乘论释》从十地所证说明:通达无分别依止得法身果;通达土及智自在依止得应身果;通达业依止得化身果;三者同以真如为依止。

(五)三身之功能分判

《摄大乘论释》以自利、利他分判三身:「法身是自利,应身与化身是利他」;又以三德摄之:「法身是断德,应身是智德,化身是恩德」;并以可见难易分判:「应、化二身易见,法身难见;法身唯于深行菩萨及诸佛为易见,于凡夫、声闻、独觉及始修行菩萨则难见」。

三、不同部类与译本的表述差异

(一)三身之异名

各经所用三身名称有别:

- 《金光明最胜王经》(经集部)以「化身、应身、法身」为序,其中「应身」取代一般常见之「报身」,乃本经特殊用词。 - 《摄大乘论释(真谛译)》(瑜伽部)并用两套术语:「自性身、应身、化身」与「自性身、受用身、变化身」。其中自性身即法身,应身亦称受用身,化身亦称变化身。另有以「依止、意、事」分别指法身、应身、化身的说法。 - 《古尊宿语录》(禅宗语录部)对报身、化身常连称「报化」,亦使用「应身」异称。 - 《景德传灯录》(史传部)临济义玄章另以「法性身」与「报化」并称,亦明用「法、报、化」三称。 - 《摩诃止观》(诸宗部)仅明举「法身」之名,总称「三身」,未列举「报身、化身」之专名。 - 《妙法莲华经玄义》(经疏部)仅明举「法身」,以「三轨」「三种身」「功德和法身,处处应现往」之引文隐括报化二身之义。 - 《摄大乘论本》(瑜伽部)仅以「三身」一词总括,未别别开名。

(二)三身真妄之辨

《古尊宿语录》载问答:「报化非真佛,亦非说法者」,答以「缘生故非」;再问「法身是真佛否」,答曰「早是应身也」;又问「离三身外何法是真佛」,师以斥语拒之,并反问「法身是真非真」。《黄檗山断际禅师传心法要》亦持此判:法身所说乃「自性虚通法」,「不可以言语音声形相文字而求」;报化身所说皆「随机感现」,「皆非真法」;故判「报化非真佛」。然《景德传灯录》临济义玄章之机语则更为彻底,反问「若是法身说,尔向什么处听」,不许于三身上分别真妄。

(三)三身之修行进路差异

- 《摩诃止观》以三衣、三观、三忍庄严三身:「三衣者,即三观也……庄严三身」,「故以三观为衣,即是伏忍、柔顺忍、无生寂灭忍也」;百一长衣「助成三观……严于三身」。 - 《六祖大师法宝坛经》以「性、智、行」配三身:「清净法身汝之性也,圆满报身汝之智也,千百亿化身汝之行也」;立「一体三身自性佛」之名,主张「此三身佛,从自性生,不从外得」。 - 《黄檗山断际禅师传心法要》以三种教法配三身:法身说「自性虚通法」,报身说「一切清净法」,化身说「六度万行法」。 - 《景德传灯录》临济义玄以「一念三光」配三身:「一念净光是汝屋里法身佛,一念无分别光是汝报身佛,一念无差别光是汝化身佛。此三身即是今日目前听法底人」。

四、与相关概念的关系

(一)三身与三轨

《妙法莲华经玄义》明示「三轨名异,义即三身」,以真性轨、观照轨、资成轨三轨摄三身之义,并标举「若此三身不纵不横,妙决了三身入法身妙」,以天台「不纵不横」之语显三身圆融互具之关系。

(二)三身与三涅槃

同上经玄义以性净涅槃(理性)、圆净涅槃(修因所成)、方便净涅槃(薪尽火灭)三涅槃旁通三身之义。

(三)三身与三宝

同上经玄义以一体三宝(真性即法宝、观照即佛宝、资成即僧宝)类通三轨,并引《思益》「知觉名为佛;知离名为法;知无名为僧」配释之。

(四)三身与四智

《六祖大师法宝坛经》与《景德传灯录》寿州智通章皆以三身与四智相即:「若离本性别说三身,即名有身无智;若悟三身无有自性,即名四智菩提」;偈云「自性具三身,发明成四智」「三身元我体,四智本心明,身智融无碍,应物任随形」。

(五)三身与三心

《金光明最胜王经》以「起事心、依根本心、根本心」三心配三身:「起事心灭故,得现化身;依根本心灭故,得显应身;根本心灭故,得至法身」;并明诸佛于化身与诸佛同事,于应身与诸佛同意,于法身与诸佛同体。

(六)三身与四土

《景德传灯录》智者大师章云:「通具法报化三身为正,随居四土为依。四土者:一常寂光,二实报无障碍,三方便有余,四净秽同居。其实则非身非土,无优无劣,为对机故假说身土而分优劣。」

(七)三身与「三身一体」

《古尊宿语录》明言「三身一体,一体三身」,以三身与一体互相表述,显示三身不可割裂;又问「三身中那个是本来身」,答以「阙一不可」。问「法、报、化三身,佛亦非说,如何是本来身」,答「海底如意珠,始终无不应」。

五、代表性原文引用

1. 《金光明最胜王经》:「一切如来有三种身。云何为三?一者、化身,二者、应身,三者、法身。如是三身具足,摄受阿耨多罗三藐三菩提,若正了知,速出生死。」

2. 《摄大乘论本》:「诸菩萨究竟,得清净三身,是无分别智,得最上自在。」「不坚业坚业,诸佛具三身。」

3. 《摄大乘论释(真谛译)》:「自性身即诸如来法身,是应化二身及如来一切功德之所依……依自性身而起福德、智慧二行,其所得净土清净与大法乐,由佛受用,故名受用身;佛依本愿自在力,于他修行地中随众生识而变异显现,故名变化身。」

4. 《古尊宿语录》:「三身一体,一体三身。」「报化非真佛,亦非说法者……缘生故非。」「三身中那个是本来身……阙一不可。」

5. 《景德传灯录》临济义玄:「一念净光是汝屋里法身佛,一念无分别光是汝报身佛,一念无差别光是汝化身佛。此三身即是今日目前听法底人,为不向外求有此三种功用。」

6. 《六祖大师法宝坛经》:「于自色身,归依清净法身佛;于自色身,归依圆满报身佛;于自色身,归依千百亿化身佛。」「清净法身汝之性也,圆满报身汝之智也,千百亿化身汝之行也。」

7. 《黄檗山断际禅师传心法要》:「佛有三身……法身说自性虚通法,报身说一切清净法,化身说六度万行法。」

金光明最勝王經T0665 · 經集部

《金光明最勝王經》(唐義淨譯,經集部)由虛空藏菩薩啟請,如來自說「一切如來有三種身」並展開論述。值得特別注意者,本經所用三身名相為「化身、應身、法身」,其中以「應身」取代一般常見之「報身」名稱,此乃本經在佛身名相上的特殊用詞。

一、總標三身。經云:「一切如來有三種身。云何為三?一者、化身,二者、應身,三者、法身。如是三身具足,攝受阿耨多羅三藐三菩提,若正了知,速出生死。」三身具足為攝受無上正等正覺之要,正確了知即得速出生死。

二、化身——隨機示現之身。經云:化身乃如來昔在修行地中,為一切眾生修種種法,由修行力得大自在,隨眾生意、隨眾生行、隨眾生界悉皆了別,不待時、不過時,處、時、行、說法皆相應,而現種種身,是名化身。其特質為「隨眾生意有多種故,現種種相,是故說多」,「第一身依於應身得顯現故」;又化身「恒轉法輪,處處隨緣,方便相續,不斷絕故」故說常,「非是本故,具足大用不顯現故」說為無常。

三、應身——應菩薩之身(本經以「應身」取代「報身」之名)。經云:應身乃如來為諸菩薩得通達故,說於真諦,為令解了生死涅槃是一味故,為除身見眾生怖畏歡喜故,為無邊佛法而作本故,如實相應,如如、如如智本願力故,是身得現具三十二相、八十種好、項背圓光,是名應身。應身特質為「弟子一意故現一相,是故說一」,「從無始來相續不斷,一切諸佛不共之法能攝持故,眾生無盡,用亦無盡」故說常,「第二身依於法身得顯現故」。

四、法身——真實根本之身。法身的內容為「如如、如如智」。經云:法身乃為除諸煩惱等障、為具諸善法故,唯有如如、如如智,是名法身。經中明示:「前二種身,是假名有,此第三身,是真實有,為前二身而作根本」,「離法如如,離無分別智,一切諸佛無有別法,一切煩惱究竟滅盡,得清淨佛地」。法身特質為「過一切種相,非執相境界,是故說名不一不二」,「是法身者,是真實有,無依處故」。

五、法身之自利利他與清淨。經云:「一切諸佛利益自他,至於究竟。自利益者,是法如如,利益他者,是如如智。」又云:「是法如如,是慧如如,是二種如如,如如不一不異,是故法身慧清淨故,滅清淨故,是二清淨,是故法身具足清淨。」

六、三身與三心之配對。經以三心配三身:「一者、起事心,二者、依根本心,三者、根本心。依諸伏道,起事心盡;依法斷道,依根本心盡;依最勝道,根本心盡。起事心滅故,得現化身;依根本心滅故,得顯應身;根本心滅故,得至法身。」並明諸佛於第一身與諸佛同事,第二身與諸佛同意,第三身與諸佛同體。

七、三身之常無常義。經云:「如是三身,以有義故而說於常,以有義故說於無常。」化身與應身皆可從不同義門論常與無常;法身則「非是行法,無有異相,是根本故,猶如虛空,是故說常」,「離無分別智,更無勝智,離法如如,無勝境界」,故法身唯常而非無常。

攝大乘論本T1594 · 瑜伽部

本論(《攝大乘論本》)論述「三身」之說,主要見於兩處偈頌段落,其論述脈絡各有側重。

其一,將「三身」置於菩薩修行究竟之果位加以說明。論中以無分別智為主軸,依次陳述菩薩自性、所依、因緣、所緣、行相,乃至任持、助伴、異熟、等流、出離等十種相。於「究竟」一項云:「諸菩薩究竟,得清淨三身,是無分別智,得最上自在。」()此處以「究竟」連結「清淨三身」,意謂菩薩至修行圓滿之位,由無分別智而得究竟清淨之三身,並得最上自在。此說將三身之獲得歸於菩薩無分別智之究竟成就,非另有所立。

其二,從佛地果德之立場論三身之具足。偈云:「不堅業堅業,諸佛具三身。」()以「不堅」與「堅」二業對舉,說明諸佛由堅固之業而具足三身。又同一段落云:「佛一切處行,亦不行一處,於一切身現,非六根所行。」()明佛身遍一切處而無定所,雖現種種身相,而非凡夫六根之所能緣。

此外,同段尚以諸喻顯佛身常住之相。如「或現等正覺,或涅槃,如火;此未曾非有,諸佛身常故」(),以火為喻說明佛身常住,非因示現涅槃而歸於斷滅;又云「諸佛過諸蘊,安住諸蘊中,與彼非一異,不捨而善寂」(),明佛身與諸蘊不即不離之關係。同段亦有「煩惱伏不滅,如毒呪所害,由惑至惑盡,證佛一切智」()之語,從煩惱與覺分之轉化顯示佛身成就之不思議方便。

要之,本論於「三身」之用語僅以「三身」一詞總括,未見法身、報身、化身之別別開名,亦無其他異稱或譯名之替換;其論述脈絡一由菩薩究竟位之無分別智而得清淨三身,一由佛地堅固之業而具足三身,並旁及佛身遍一切處、常住、不離蘊、非六根所行等德相。

攝大乘論釋(真諦譯)T1595 · 瑜伽部

《攝大乘論釋(真諦譯)》將三身列為無分別智之果,並明言「三種佛身,自性身、應身、化身」。三身之所以必須成立,在於彼此具有依止與作用的次第:自性身為法身成立之本,法身為應身所依;應身使已入大地的菩薩受用法樂、具足菩提資糧,又是化身成立的條件;化身則令願樂位菩薩及初發修行者得以成就。因此,三身共同構成無分別智的圓滿果相。

本論在專門解釋三身時,又採用「自性身、受用身、變化身」一組名稱。自性身即諸如來法身,是應化二身及如來一切功德之所依;「身」既有依止義,也有真實、不破壞之義。法身屬自性得,受用身與變化身則屬人功得:依自性身而起福德、智慧二行,其所得淨土清淨與大法樂,由佛受用,故名受用身;佛依本願自在力,於他修行地中隨眾生識而變異顯現,故名變化身。

就異譯名歸一而言,本論並用兩套術語:「自性身、應身、化身」與「自性身、受用身、變化身」。其中自性身即法身,應身亦稱受用身,化身亦稱變化身。另有以「依止、意、事」分別指法身、應身、化身的說法,並指出十方三世一切如來在此三身上平等無異。

三身的功能以自利、利他分判:法身是自利,應身與化身是利他;三身於究竟修位成就,能平等利益自他。又說轉依是取得法身四德之本,而菩薩於長時修習無分別智及後得智、已得轉依之後,仍為取得三種佛身更修加行。

本論亦從十地所證說明三身之果:通達無分別依止,得法身果;通達土及智自在依止,得應身果,能在大集中與眾生共受法樂;通達業依止,得化身果,能為無量眾生作無邊利益。三者同以真如為依止,並與菩薩在十地所得的自在相連。

三身又被概括為三德:法身是斷德,應身是智德,化身是恩德。可見性方面,應、化二身易見,法身難見;法身唯於深行菩薩及諸佛為易見,於凡夫、聲聞、獨覺及始修行菩薩則難見。

就遍滿與不離而言,法身之處所不可度量,應、化二身亦然;不可說某一世界有而另一世界無,且無一法出法身外,無有眾生界出應、化二身外。諸佛法身雖無差別,而證得此法身的依止眾多;三身實體常住,故稱無上,但應身之業堅固真實,化身之業則以權方便引導二乘,後再由應身教其修菩薩道。

最後,本論以三身顯示菩薩解脫知見與二乘的差別:二乘不能滅智障,故不得圓滿清淨法身;又因無大慈悲、不行利益他事,故無應、化二身。菩薩具足此二義,因而有三身;在果位中,法身是自利方便,應、化二身是利他方便。
