What this concept is saying

發趣大乘 (*fāqù dàchéng*, “setting forth and advancing in the Great Vehicle”; Sanskrit: *mahāyāna-prasthāna*) is not merely the moment when someone decides to become a Buddhist, nor is it a synonym for studying Mahāyāna doctrine. It is the whole practical movement by which a bodhisattva takes buddhahood and the liberation of beings as the destination, practices the six perfections, cultivates the work proper to each bodhisattva ground, and advances toward the Buddha-ground.

The *Mahāprajñāpāramitā Sūtra* (《摩訶般若波羅蜜經》) summarizes 大乘發趣 (*dàchéng fāqù*, “the Great Vehicle’s course of advancement”) as “行六波羅蜜時,從一地至一地”—“while practicing the six pāramitās, [one goes] from one ground to another.” The *Great Treatise on the Perfection of Wisdom* (《大智度論》) explains this with the striking statement “大乘即是地”: here, the “Great Vehicle” is not simply a body of teachings one professes; it is the terrain one actually traverses.

Yet “advancing” does not mean accumulating spiritual credentials. Four elements have to remain inseparable:

1. The direction of bodhicitta. The practitioner wishes “to become a Buddha and liberate beings”—欲作佛,度眾生. This is not a wish for private excellence. One seeks awakening because beings suffer and because only complete buddhahood can fulfill the intended work without remainder.

2. **The orientation toward 薩婆若 (*sarvajñā*, here the Buddha’s all-knowing wisdom).** The texts repeatedly speak of 應薩婆若心, a mind corresponding to this wisdom, and 迴向薩婆若, dedicating wholesome roots toward it. The same generosity, ethical discipline, meditation, or learning may lead in different directions according to the intention governing it. A bodhisattva does not dedicate these attainments merely to worldly happiness, a fortunate rebirth, personal security, longevity, or even the attainments associated with a śrāvaka or pratyekabuddha. They are gathered toward complete awakening for the sake of beings.

3. The six pāramitās as mutually permeating practice. These are not six boxes checked in sequence.

- 檀那波羅蜜 (*dāna-pāramitā*, the perfection of giving) gives material aid, protection, and Dharma without fastening upon giver, recipient, or gift as independently existing. - 尸羅波羅蜜 (*śīla-pāramitā*, the perfection of ethical discipline) restrains what harms and preserves the direction of the bodhisattva path. In the cited exposition, refusing to let one’s practice turn toward the śrāvaka or pratyekabuddha goal is itself an aspect of this discipline. - 羼提波羅蜜 (*kṣānti-pāramitā*, the perfection of patience or receptive endurance) includes the willing acceptance of hardship, but is not merely gritting one’s teeth. It is also the mind that deeply welcomes and consents to the work of benefiting beings and seeking all-aspect wisdom. - 毘梨耶波羅蜜 (*vīrya-pāramitā*, the perfection of energetic perseverance) is sustained, purified effort: continuing the work and dedicating it to all-aspect wisdom without slackening. - 禪那波羅蜜 (*dhyāna-pāramitā*, the perfection of meditative cultivation) includes the four meditative absorptions and the four immeasurable minds—loving-kindness, compassion, appreciative joy, and equanimity—but does not end in attachment to refined states. - 般若波羅蜜 (*prajñāpāramitā*, the perfection of wisdom) sees conditioned states as impermanent, stressful, and not-self, and knows emptiness, signlessness, and wishlessness without turning any of these contemplations into a possession.

The scripture illustrates their interpenetration through meditation itself. When a bodhisattva cultivates *dhyāna* and resolves to teach beings from what has been gained, meditation contains giving. Not accepting a narrower liberation as the final destination brings ethical discipline into it. Gladly embracing the aim of benefiting beings and attaining all-aspect wisdom brings patience into it. Practicing continuously and dedicating the wholesome roots to that wisdom brings vigor into it. Contemplating the meditative states and their factors as impermanent, stressful, not-self, empty, signless, and wishless—“用無所得故,” on account of non-attainment—brings wisdom into it.

The four immeasurables are treated in the same integrated way. Loving-kindness seeks beings’ welfare; compassion responds to their suffering; appreciative joy is free of rivalry toward their good; equanimity is impartial and does not abandon them. These intentions can express giving, discipline, patience, vigor, meditation, and wisdom when they remain directed toward all-aspect wisdom and when the practitioner does not become reborn, as it were, inside attachment to the meditative experience itself.

Nor is 發趣大乘 limited to meditation. The text says that the bodhisattva cultivates “in every mode” the four establishments of mindfulness through the factors of the Noble Eightfold Path, the three gates of liberation, and even the distinctive qualities of a Buddha. Practices shared with other Buddhist paths become part of the Great Vehicle through their bodhicitta, dedication, compassionate purpose, and non-grasping wisdom.

4. Gradual cultivation without reifying the stages. The bodhisattva goes “from one ground to another,” yet knows that no independently existing traveler departs, no solid ground is entered, and no attainment passes from one location to another. This is not a denial of training. It is training without turning its map into a metaphysics of spiritual identity.

The first ground is therefore cultivated through ten concrete matters: firmness of profound intention, equality toward beings, generosity, association with spiritual friends, seeking the Dharma, a life of renunciation, delight in the Buddha’s body, proclaiming the Dharma, breaking pride, and truthful speech. Their wisdom-background is that “being,” “giver,” “recipient,” “Dharma,” physical marks, and language cannot be seized as self-existing entities.

The second ground includes purified discipline, knowing and repaying kindness, patience, joyfulness, not abandoning beings, great compassion, respectfully consulting teachers, and diligently seeking the pāramitās. The third includes tirelessness in learning, pure giving of Dharma, adorning or purifying a buddha-land, enduring hardship, and dwelling in moral conscience and appropriate shame.

The *Great Treatise* records two systems of “grounds.” Its specifically bodhisattva sequence should be preserved in the terminology used there: 歡喜地, 離垢地, 有光地, 增曜地, 難勝地, 現在地, 深入地, 不動地, 善根地, and 法雲地. These names should not casually be replaced by terms borrowed from another translation system. The point relevant here is that a ground is both a maturation of understanding and a field of work that must be cultivated.

The paradox at the heart of the concept is thus exact: one cultivates the grounds without finding a ground; knows distinctions without taking them as fixed realities; and works toward buddhahood without manufacturing a permanent “future Buddha” who owns the journey.

This is the meaning of 無所得 (*anupalambha*, “non-apprehension” or “non-attainment”). It does not mean ignorance, passivity, or the claim that nothing matters. The scripture says that the bodhisattva’s wisdom does not settle into past, present, or future; the three realms; worldly or supramundane; conditioned or unconditioned; contaminated or uncontaminated—and yet “亦非不知,” it is not that these are unknown. Wisdom can distinguish without freezing distinctions into self-existing things. It can use the map without mistaking the lines on the map for walls in reality.

A walkthrough in ordinary life

Imagine a crowded evening commute after a difficult day. Your phone shows a message from your partner: “You never listen. Don’t bother coming home early.” Almost immediately, a second notification arrives: a colleague has publicly blamed you for a delay.

The ordinary reaction is fast. The body tightens; hurt appears; the mind recognizes the messages as accusation; defensive impulses begin composing replies; consciousness keeps lighting up one provocative phrase after another. 發趣大乘 does not ask you to pretend these processes are absent. It asks what direction you will give them.

First comes the governing intention. Instead of asking only, “How do I protect my status?” you remember: “May my response reduce suffering rather than multiply it; may even this become material for awakening.” This is a small, situational expression of bodhicitta and 應薩婆若心. It is not yet buddhahood, and it does not make every mental state that follows superior to the accomplishments of advanced practitioners. It establishes the direction of travel.

Then the six pāramitās can be walked through without forcing the situation into six artificial compartments.

Giving: You give the other person space, attention, and the possibility of being heard. Perhaps you put the phone away until you can reply carefully. Later you offer an honest conversation rather than a retaliatory performance. Giving here is not simply donating money. What is given may be time, safety, information, forgiveness, or Dharma. But giving does not mean surrendering every boundary or enabling abuse; what genuinely benefits another may include a firm refusal.

Ethical discipline: You refrain from the cutting sentence that would feel satisfying for thirty seconds and damage trust for months. You do not fabricate evidence against your colleague. More deeply, you do not let the practice collapse into the private goal “I just want to become invulnerable and never be disturbed again.” Discipline protects both conduct and the path’s compassionate orientation.

Patience: You allow hurt and anger to be present without obeying them. You also accept that benefiting people is often slow, ambiguous, and unrewarded. Patience is commonly mapped incorrectly as passive submission. In its classical sense here, it is a strength capable of receiving difficulty and continuing to welcome the bodhisattva aim. A patient response can still be clear, forceful, and protective.

Vigor: You do the unglamorous work: check what actually happened, acknowledge your own part, document the colleague’s error without exaggeration, and return to the conversation after both parties have cooled down. Vigor is not frantic productivity or compulsive overtime. It is sustained energy purified by the goal toward which it is directed.

Meditative cultivation: Before replying, you steady attention. You may cultivate loving-kindness toward yourself and the other person, compassion for the distress underneath the accusation, appreciative joy for whatever remains good in the relationship, and equanimity that does not divide the scene into an absolutely righteous self and an absolutely wicked other. This is not emotional anesthesia. Nor is a calm nervous system automatically *dhyāna-pāramitā*. Calm becomes part of Great Vehicle advancement when it supports wisdom and compassionate action rather than withdrawal or self-enclosure.

Wisdom: You examine the experience without fixing it into “This is who I am” or “This is what they always are.” The accusation arose through wording, past tensions, exhaustion, expectations, workplace pressures, memory, and interpretation. Its effects are real, but it possesses no isolated, immutable essence. Your calm state is also impermanent; it is not a spiritual trophy. You respond to causes and consequences while finding no solid owner of anger, no eternally guilty opponent, and no reply that can be possessed as “my attainment.” This is non-attainment in action.

Now consider the ground-work embedded in the same scene. Firm intention keeps you from abandoning the path under pressure. Equality toward beings prevents you from treating your partner’s pain as important but your colleague’s humanity as disposable. Seeking counsel from a wise friend checks your blind spots. Truthful speech prevents both self-exoneration and self-condemnation. Breaking pride allows an apology where one is due. Gratitude remembers previous kindness and keeps one conflict from erasing the whole relationship. Not abandoning beings means neither discarding the difficult person nor sacrificing yourself to their every demand.

Finally comes dedication. You do not make the outcome merely, “I handled that brilliantly; I am now the mature one.” Whatever clarity or restraint appeared is dedicated toward awakening and the relief of suffering. This guards even good conduct from becoming new material for self-importance.

The same walkthrough applies to algorithmic life. Suppose you are scrolling short videos and encounter a stranger being mocked. Giving may mean offering useful context or refusing to monetize their humiliation with your attention. Discipline may mean not forwarding unverified claims. Patience may mean tolerating uncertainty rather than joining an instant moral mob. Vigor may mean checking the source. Meditation may mean noticing the pull of outrage without being carried away by it. Wisdom sees that the platform, recommendation system, crowd response, creator, and your own habits condition one another—without equating an algorithm with karma, mind, or dependent origination.

AI and cognitive science can help describe limited parts of such episodes: attentional capture, predictive processing, habit formation, reinforcement, and emotional regulation. These comparisons may make Buddhist analysis more approachable, but they do not prove the Buddhist path. Scientific models remain contested and methodologically limited; they generally investigate measurable processes, not the full normative question of liberation, bodhicitta, karma, or buddhahood.

Why contemporary people need it

Contemporary culture is rich in techniques but poor in shared answers to the question “Toward what?” Meditation can be used to make an employee tolerate an unhealthy workplace. Generosity can become branding. Discipline can become moral superiority. Learning can become identity decoration. Even compassion can become a way of needing to be seen as compassionate.

發趣大乘 insists that no practice can be understood fully apart from its direction, dedication, and view. It asks three searching questions:

- What kind of mind is doing this? - For whose benefit is it being done? - What reality is the practitioner imagining while doing it?

The first question exposes motivation. The second opens private cultivation toward all beings. The third prevents compassionate effort from hardening into a drama of a permanent savior rescuing permanently defective others.

This framework is especially valuable because it joins vast aspiration to incremental formation. “Liberate all beings” can otherwise remain magnificent rhetoric. The grounds bring the vow down into truthful speech, gratitude, learning, humility, ethical restraint, consultation with good teachers, willingness to endure difficulty, and refusal to abandon beings. The path is vast precisely because it has to enter the smallest habits.

At the same time, non-attainment protects gradual cultivation from turning into a spiritual ranking system. Without stages, one may confuse inspiration with maturation. With reified stages, one may become obsessed with status: “Which ground am I on?” The Prajñāpāramitā approach retains disciplined progression while removing the imagined owner of the progression.

The *Great Treatise* illustrates differences in pace through three vehicles. One burdened by much unwholesomeness and little merit is like someone traveling on a sheep: the journey is long, and arrival uncertain. One with more merit and less unwholesomeness is like a rider on a horse: by gradually practicing the six pāramitās, that person reaches the destination. One whose wholesome qualities are thoroughly purified is like someone traveling by supernormal power: entry into the bodhisattva position and 阿鞞跋致 (*avaivartika*, non-retrogression) may be swift.

The point is not to label other practitioners as sheep. It is that a noble destination does not erase differences in preparation, habits, obstacles, and momentum. A person may sincerely raise bodhicitta while still possessing unstable attention, poor judgment, or deeply conditioned reactions. Aspiration is precious; formation remains necessary.

This also gives hope without fantasy. Slow progress is still progress when direction, practice, and wisdom are aligned. One need not imitate another person’s speed. What matters is to purify the causes of travel: bodhicitta, wholesome roots, the six pāramitās, the work of the grounds, spiritual friendship, and non-grasping wisdom.

In the whole path of liberation, then, 發趣大乘 occupies the space between the first vast vow and its complete embodiment in buddhahood. Bodhicitta determines the horizon. The six pāramitās train the whole person. The grounds describe maturation. Non-retrogression marks stability. Non-attainment prevents the path from becoming another object of clinging. Skillful means allows the bodhisattva to pass through the grounds and abide in the Buddha-ground without abandoning beings along the way.

Common misreadings and clarifications

“It means deciding to identify as a Mahāyāna Buddhist.” No. Affiliation may provide a context, but 發趣 is an enacted trajectory: aspiration, dedication, the six pāramitās, cultivation of the grounds, benefit to beings, and wisdom without appropriation.

“A compassionate intention is enough; details of conduct are secondary.” The initial resolve “to become a Buddha and liberate beings” is profoundly valuable, but it does not automatically perfect one’s meditation, ethical discipline, wisdom, or liberative capacities. The *Great Treatise* explicitly resists the inference that a beginner’s noble intention makes every attainment superior to those of śrāvakas or pratyekabuddhas. Direction matters, and so does actual cultivation.

“Rejecting the two vehicles means despising their practitioners or practices.” It does not. The bodhisattva cultivates many shared practices, including the establishments of mindfulness and the factors of the Noble Eightfold Path. What is refused is making personal liberation the final scope of the vow. Contempt would contradict equality, compassion, and non-grasping.

“The six pāramitās are six unrelated virtues.” The scripture’s treatment of meditation shows otherwise. One practice can contain all six according to how it gives, restrains, receives difficulty, perseveres, concentrates, and understands. Their unity lies in bodhicitta, dedication to all-aspect wisdom, and non-attainment—not in erasing their distinct classical meanings.

“Patience means tolerating mistreatment.” Patience is not servility. It prevents hatred and hardship from overthrowing the bodhisattva aim. Protecting oneself or another, setting a boundary, reporting abuse, or intervening firmly can be fully compatible with patience when done without cruelty and with clear discernment.

“Vigor means working harder.” Vigor is not busyness, sleeplessness, or obedience to productivity culture. Effort becomes *vīrya-pāramitā* through its wholesome object, continuity, compassionate purpose, and dedication to awakening.

“Meditative bliss proves advanced realization.” No. Refined concentration remains conditioned. The bodhisattva contemplates the absorptions and their factors as impermanent, stressful, not-self, empty, signless, and wishless, and does not become bound to the meditative state. A pleasant state may assist the path, but it is not the destination.

“Non-attainment means there are no stages and nothing to practice.” This reverses the teaching. The texts describe detailed work for successive grounds while denying that any ground exists as a self-established possession. Conventional distinctions guide cultivation; wisdom prevents appropriation. “No attainment” removes clinging to practice, not practice itself.

“If no being, giver, recipient, or ground can ultimately be found, compassion becomes pointless.” The intended conclusion is the opposite. Emptiness removes fixed separation; it does not erase suffering or causal responsibility. Because persons and situations arise dependently, they can change, and actions matter. The bodhisattva responds fully without constructing an eternal victim, an eternal enemy, or an eternal rescuer.

“Advancing from ground to ground describes a spiritual self moving upward.” The texts explicitly say that phenomena have no coming-and-going characteristic. The language of progress describes transformation in qualities and capacities, not the migration of a permanent spiritual entity. There is cultivation, but no fixed cultivator can be seized.

“All-aspect wisdom is simply having access to all information.” 薩婆若 and 一切種智 are buddhological terms, not ancient names for a database, search engine, or superintelligent AI. Computational breadth can serve as a limited analogy for range of information, but it lacks the doctrinal content of complete awakening, the exhaustion of obscurations, and liberative wisdom. Equating the two would flatten both Buddhism and computer science.

Ultimately, 發趣大乘 asks for something more demanding than either idealism or self-improvement. It asks us to form a mind vast enough to include all beings, disciplined enough to enter ordinary conduct, patient enough to mature through stages, and wise enough not to turn even buddhahood into something the self can own. The journey is real as practice, empty as possession, and boundless in its intended benefit.

1. 定义与核心要义

「发趣大乘」(mahāyāna-prasthāna)指菩萨摩诃萨以成佛度众生为方向,行六波罗蜜,修治地业,从一地进趣一地,乃至以方便力住于佛地的实践历程。《摩诃般若波罗蜜经》与《大智度论》均交替使用「发趣大乘」和「大乘发趣」;前一语序多着重何种修行构成大乘进趣,后一语序则直接界定为行六波罗蜜时「从一地至一地」。

其核心不仅在修行项目,更在「应萨婆若心」与「回向萨婆若」:菩萨不将禅定、布施等功德导向声闻、辟支佛地,而回向一切种智,愿作佛并断除众生烦恼。进趣虽有地次,般若观照中却无实有之地、来去者或所得法;故其基本结构是菩提心、六度万行、次第修治与无所得智慧相即而行。

2. 主要阐述

《摩诃般若波罗蜜经》以六波罗蜜互摄说明发趣。修禅那波罗蜜时,愿以所得为众生说法,即摄檀那;不受声闻、辟支佛心,即摄尸罗;对利生及一切种智之心欲乐忍可,即摄羼提;回向一切种智而勤修不息,即摄毘梨耶;观四禅及其支为无常、苦、无我、空、无相、无作而无所得,即摄般若。修慈、悲、喜、舍四无量心时,也由安乐、救济、度脱众生,不向二乘地,忍乐欲求一切种智,清净勤行及「不随禅无量心生」等义统摄六度。

发趣所摄法门不限于禅定。菩萨以「一切种修」修四念处乃至八圣道分、三解脱门乃至十八不共法,使道品、解脱门及佛之功德皆归于大乘进趣。

其智慧以「用无所得故」为反复出现的限定。菩萨于诸空中用智慧而无所得,于一切法「不乱不定」,不住常与无常、乐与苦、实与空、我与无我等二边;其智不行三世、三界,也不行世间与出世间、有为与无为、有漏与无漏,而又「亦非不知」。因此,无所得并非不知诸法,而是不以分别执取为实有。

就地次而言,菩萨知一切法无来去相,于诸地不念、不思惟,仍修治地业而不见有地。初地修深心坚固、等心、布施、亲近善知识、求法、常出家、爱乐佛身、演出法教、破憍慢、实语十事,并以众生、施者受者、法、相好及语言等不可得为般若背景;二地满足戒净、报恩、忍辱、欢喜、不舍众生、大悲、敬师咨受及勤求波罗蜜八法;三地修多闻无厌、清净法施、庄严佛土、忍受勤苦及住惭愧五法。

《大智度论》另以羊、马、神通三喻说明发心者进趣迟速:罪多福少者如乘羊,久远而或至或不至;福多罪少者如乘马,渐行六度而必至;纯行清净福德者如乘神通,或初发心即入菩萨位、得阿鞞跋致,或经少分供养、通达菩萨道后入位。

3. 不同部类与译本的表述差异

般若部《摩诃般若波罗蜜经》以「萨婆若」及「一切种智」并称所应、所回向的智慧目标;六度作「檀那、尸罗、羼提、毘梨耶、禅那、般若波罗蜜」,四无量作「慈、悲、喜、舍心」或「无量心」,二乘作「声闻、辟支佛」。其「菩萨摩诃萨发趣大乘」段偏重禅、无量心、道品与六度互摄,「菩萨摩诃萨大乘发趣」段则偏重从一地至一地及各地修治。

释经论部《大智度论》承用「萨婆若」「阿耨多罗三藐三菩提」「阿鞞跋致」等词,并明释「大乘即是地」。论中列出两套地名:共地为干慧地乃至佛地;但菩萨地依次为欢喜地、离垢地、有光地、增曜地、难胜地、现在地、深入地、不动地、善根地、法云地。此处依论中文字照录,不以其他十地译名替换。

现有材料只涉及《摩诃般若波罗蜜经》及其论释《大智度论》,未提供同经其他异译本,故无可据以列举的同经异译词形分歧。

4. 与相关概念的关系

发趣大乘以菩提心为方向:「欲作佛,度众生」使修行成为佛乘之行;但《大智度论》同时指出,不可因此便推定发心者的一切禅定、解脱功德均已胜过二乘。「萨婆若心」决定功德所向,「六波罗蜜」构成主要实践,「菩萨地」呈现进修次第,「阿鞞跋致」表示不退转,而「无所得」则使菩萨修地而不执地、知法而不住法。

5. 代表性原文引用

《摩诃般若波罗蜜经》以「行六波罗蜜时,从一地至一地」概括大乘发趣,又以「用无所得故」标示其般若立场。《大智度论》释为「大乘即是地」,并说菩萨次第进升、越过诸地而住佛地;其发趣方向则是所作功德不求世间福乐,「唯为萨婆若」。论中沙弥发心譬喻以「欲作佛,度众生」突出初发大乘心的殊胜,同时将偏执发心即全面胜过二乘的理解摄归中道。

摩訶般若波羅蜜經T0223 · 般若部

本經以「發趣大乘」為菩薩摩訶薩修行之總綱,由慧命舍利弗問、富樓那彌多羅尼子答之問答結構展開。其核心義為:菩薩於一切修行中,以「應薩婆若心」為根本動機,將諸善根「迴向薩婆若」,不墮聲聞、辟支佛地,是即發趣大乘。

本經獨特之處在於以六波羅蜜互攝之方式論發趣大乘。富樓那先以禪那波羅蜜為主軸,說明菩薩離欲入初禪乃至第四禪,行慈、悲、喜、捨四無量心,將諸禪及無量心「共一切眾生迴向薩婆若」,名為禪那波羅蜜發趣大乘。 繼而逐一開出:住禪無量心而念「我當得一切種智,為斷一切眾生煩惱故當說法」,是行禪那波羅蜜時檀那波羅蜜;應薩婆若心修禪而「不受餘心,所謂聲聞、辟支佛心」,是尸羅波羅蜜;入諸禪而欲樂忍於斷眾生煩惱之說法,是羼提波羅蜜;諸善根迴向薩婆若、懃修不息,是毘梨耶波羅蜜;觀無常、苦、無我、空、無相、無作諸相而迴向薩婆若,是般若波羅蜜。

四無量心亦各攝六度:行慈心念安樂一切眾生、悲心念救濟、喜心念度脫、捨心念令得漏盡,是檀那波羅蜜;不向聲聞辟支佛地但迴向薩婆若,是尸羅波羅蜜;不貪二乘地但忍樂欲薩婆若,是羼提波羅蜜;應薩婆若心行清淨行,是毘梨耶波羅蜜;入禪入無量心而「不隨禪無量心生」,是方便般若波羅蜜。

此外,本經更以般若無所得之智慧廣說發趣大乘:一切種修四念處乃至八聖道分、三解脫門乃至十八不共法,是發趣大乘;內空乃至無法有法空中智慧「用無所得故」,是發趣大乘;一切法中不亂不定智慧,是發趣大乘;非常非無常、非樂非苦、非實非空、非我非無我之智慧,是發趣大乘;智不行三世而亦非不知三世,不行三界而亦非不知三界,不行世間出世間、有為無為、有漏無漏法而亦非不知,皆「用無所得故」,是名發趣大乘。

術語方面,本經以「薩婆若」音譯稱一切智(一切種智),以「慧命」為舍利弗之尊稱,以「覺觀」稱初禪尋伺(非後世通用之「尋伺」),以「無作相」稱無願解脫門之相,六度皆用音譯:檀那、尸羅、羼提、毘梨耶、禪那、般若。

大智度論T1509 · 釋經論部

《大智度論》以「發趣大乘」為菩薩摩訶薩修行之總綱,反覆以「是名菩薩摩訶薩發趣大乘」作結,從多個層面界定其內涵。

一、以般若空慧為體,以「無所得」為宗。經中列舉:內空中智慧乃至無法有法空中智慧,「用無所得故」,是名發趣大乘;一切法中不亂不定智慧,是名發趣大乘;非常非無常、非樂非苦、非實非虛、非我非無我智慧,用無所得故,是名發趣大乘。又言發趣大乘智「不行過去世、不行未來世、不行現在世,亦非不知三世」;不行欲界、色界、無色界,亦非不知三界;不行世間法、出世間法,不行有為法、無為法,不行有漏法、無漏法,亦非不知諸法,皆以「用無所得故」收束。此中「不行……亦非不知」之雙遮句式,為本論論述發趣大乘之獨特用語,意謂智不取著而亦非斷滅無知。此外,一切種修三解脫門乃至十八不共法,亦名為發趣大乘。

二、以禪定神通為發大莊嚴之基。論中設問:六波羅蜜何以先說禪波羅蜜?答曰:菩薩若無禪定,心未離欲,雖行餘波羅蜜則易壞;行禪波羅蜜能入慈無量,得五神通,物無能傷,故能發大莊嚴。引佛喻:「鳥無兩翼,不能飛翔;菩薩無神通力,不能發大莊嚴」。此將發趣大乘與「發大莊嚴」相聯,強調禪定為其不可破壞之保障。

三、以十地為「發趣」之階位。論中明言「大乘即是地」,地有十分,從初地至二地是名「發趣」;以乘馬趣象、捨馬乘象、乘象趣龍為喻,顯示逐地轉進之義。地分二種:共地(乾慧地乃至佛地)與但菩薩地(歡喜地、離垢地、有光地、增曜地、難勝地、現在地、深入地、不動地、善根地、法雲地),其相如《十地經》廣說。本論用「發趣地」與「發趣大乘」互訓,謂大乘即地,發趣大乘即發趣於十地。

四、以「應薩婆若心」為入初地之深心。論釋入初地菩薩應行十法,首為深心。佛答:「應薩婆若心,集諸善根。」薩婆若心者,菩薩初發阿耨多羅三藐三菩提意,作願「我於未來世當作佛」;「應」者,繫心願我當作佛。深心者,深樂佛道,世世於世間心薄;所作一切功德,若布施、持戒、修定,不求今世後世福樂壽命安隱,但為薩婆若。論又以慳貪人積財望增長為喻,謂菩薩積集福德不向餘事,但向薩婆若。並舉摩訶迦葉棄金色女、耶舍長者子捨寶屐渡水趣佛為例,明利根煩惱薄者雖未得薩婆若之味,亦能得深心。

五、以行十地至佛地為發趣大乘之究竟。論末總結:菩薩行六波羅蜜,以方便力故,過乾慧地乃至菩薩地,住於佛地;佛地即是第十地。「菩薩能如是行十地,是名發趣大乘」。此以六波羅蜜與方便力為行持,以十地圓滿、住於佛地為發趣大乘之歸趣。

綜觀本論,「發趣大乘」一語貫穿般若空慧(無所得)、禪定神通(發大莊嚴)、十地階位(逐地轉進)、深心回向(應薩婆若心)與究竟佛地五個層面,術語上以「發趣大乘」與「發趣地」互訓,以「用無所得故」為反覆出現之判定語,以「不行……亦非不知」為遮詮句式,構成《大智度論》論述此概念之獨特面貌。
