What This Concept Is About

"Rely on scriptures of definitive meaning, not on scriptures of provisional meaning" (依了義經不依不了義經) is a seemingly simple but in fact extremely profound principle of reliance within bodhisattva practice. It belongs to the "four reliances of the bodhisattva" (四依法) — which in order are: rely on the meaning, not on the words; rely on wisdom, not on consciousness; rely on scriptures of definitive meaning, not on scriptures of provisional meaning; rely on the Dharma, not on the person. These four items form a complete system for discerning and selecting teachings: first one recognizes what true meaning is between "words" and "meaning," then recognizes what correct observation is between "consciousness" and "wisdom," and only then can one further discern "what constitutes the ultimate teaching" amid the vast ocean of scriptures, and finally, between "person" and "Dharma," one does not mistakenly choose what to rely on because of a teacher's authority and virtue.

The position of this item within the entire path of liberation is that it serves as the crucial bridge from "hearing the correct Dharma" (śrutamayī prajñā) toward "reflecting in accordance with reasoning" (cintāmayī prajñā). When a beginner faces the vast and numerous scriptural canon of Buddhism, the first question is not "which scripture is most authoritative," but rather "which category of teaching can lead me to the ultimate." The third of the four reliances is precisely what answers this question.

"Definitive meaning" (了義, nītārtha) and "provisional meaning" (不了義, neyārtha), according to the definition given in the *Mahāparinirvāṇa-sūtra* (Southern version, 《大般涅槃經(南本)》), have three layers of core criteria:

First layer: judging by vehicle — "The śrāvaka vehicle is called provisional meaning; the unsurpassed Great Vehicle is alone called definitive meaning." The reason for this distinction is not that the śrāvaka teachings are wrong, but that those of śrāvaka faculties, upon hearing the Tathāgata's "profound and secret treasury," would give rise to doubt and confusion, "not knowing that this treasury issues from the great ocean of wisdom, like an infant who knows nothing distinctly" (不知此藏出于大智海,如婴儿无所别知); whereas bodhisattvas, with true wisdom, "can follow their own minds, and with unobstructed great wisdom know everything, like adults" (能随其自心,以无碍大智如大人般无所不知). This is a judgment made according to the faculties of the audience and the depth of their realization.

Second layer: judging by proposition — To say that "the Tathāgata is impermanent and subject to change," to say that "the Tathāgata is nourished by food," to say that "the Tathāgata enters nirvāṇa like a fire that is extinguished when the firewood is spent" — all these are called provisional meaning; to say that "the Tathāgata is permanent and unchanging," to say that "the Tathāgata abides in the dharma-nature (dharmatā)" — these are called definitive meaning. Furthermore, "what is spoken by śrāvakas and should be understood and realized" (聲聞所說應證知者) is called provisional meaning; "what is spoken by bodhisattvas and should be understood and realized" (菩薩所說應證知者) is called definitive meaning. This is a judgment made according to the ultimate purport revealed by the teaching.

Third layer: judging by the sequence of transformation — The Tathāgata, for the sake of liberating sentient beings, teaches the śrāvaka vehicle through skillful means (upāya), "like a wealthy elder teaching his son the half-letters of the alphabet" (譬如長者教子半字), or like "first plowing before yet obtaining the fruit" (初耕而未得果實); therefore it is called provisional meaning. The Mahāyāna Dharma should be relied upon and is called definitive meaning. Note: this criterion does not deny the transformative function of provisional teachings; rather, it clearly establishes that when it comes to what one relies upon, relying on the Mahāyāna definitive meaning is what is ultimate.

More subtly, the *Mahāparinirvāṇa-sūtra* further interprets "definitive meaning" as a state of practice — "contentment" (知足): not feigning an appearance of dignified conduct and purity, not being arrogant and self-important, not greedily seeking offerings and benefits, and not generating attachment toward the teachings the Tathāgata spoke through appropriate skillful means. One who can abide in this is said to "already abide in the ultimate truth" (已住第一義). Therefore, the distinction between "definitive meaning" and "provisional meaning" lies not only in the content of scriptural passages, but also in whether the reader of the scriptures can discern skillful means and avoid grasping.

And the point most easily overlooked is this: for highly generalized statements such as "all is burning, all is impermanent, all is suffering, all is empty, all is selfless," this sūtra also calls them provisional meaning. The reason is extremely profound: if one cannot understand their meaning and grasps at them, one will then interpret nirvāṇa itself as burning and impermanent, and likewise apply suffering, emptiness, and selflessness to it — that is to say, if negating statements themselves are grasped as absolute truth, they will in turn negate the very nirvāṇa they are meant to point toward.

Taken together, "relying on scriptures of definitive meaning" requires the practitioner to possess three abilities: discerning the depth of the vehicle, discerning whether a proposition is ultimate, and maintaining an attitude of contentment without grasping. It is not a simple "scripture-selection guide," but rather a holistic attitude that runs through hearing, reflection, and practice.

The *Mahāparinirvāṇa-sūtra* concludes with "definitive meaning means thoroughly penetrating all Mahāyāna scriptures" (了義者,了達一切大乘經典), and extends the four reliances into a general criterion for judging whether all scriptural teachings (vinaya, abhidharma, sūtra) are fit to be relied upon: if they do not contradict the four reliances, they should also be relied upon; if they do contradict them, the corresponding parts should not be relied upon.


A Walk-Through in Everyday Life

The difficulty of this section lies in this: "Rely on scriptures of definitive meaning, not on scriptures of provisional meaning" appears to be a principle about reading scriptures, but its core is actually an ability to discern what constitutes ultimate true meaning. This ability is not only used for reading scriptures; it is also used when facing all information, all teachings, and all "life guides." Let us walk through scenarios familiar to contemporary people.

Scenario One: "Scripture-selection anxiety" in an age of information overload

Open any knowledge platform today, and you are flooded with "must-read books for life," "ten books that change your destiny," "master's teachings," "shortcuts to practice," "spirituality verified by science"... dense and of every conceivable position. If we analogize Buddhist scriptures to today's vast "spiritual growth literature," what "rely on scriptures of definitive meaning, not on scriptures of provisional meaning" asks is: when all of these claim to be able to carry you to the other shore, which category can actually deliver you there?

The criterion given by the scriptures is not "which is most popular" or "which master has the most followers," but rather penetrating through to the true meaning behind the discourse. If a passage merely teaches people to alleviate anxiety and obtain inner peace, that is "first plowing" — valuable, but not necessarily definitive meaning; if a passage directly points to the true appearance of impermanence, selflessness, and nirvāṇa, pointing to the dharma-nature that you can personally realize, that is "the fruit," and is definitive meaning.

And the most dangerous thing is not reading the "wrong" books, but reading any book and stopping at the literal surface — reading "all is impermanent" as "therefore life has no meaning," reading "all is empty" as "therefore there is no need to make any effort." The scriptures clearly point out that this manner of grasping is itself a way of trapping nirvāṇa within the framework of impermanence.

Scenario Two: Facing practice advice from different teachers and different schools

The yoga teacher says the breath is everything; the Chan master says do not attach to any method; psychology says noticing your emotions is practice; some courses say mantra recitation brings the swiftest attainment. All of them cite scriptures, all claim lineage, and all have people who have benefited.

The application of "rely on scriptures of definitive meaning, not on scriptures of provisional meaning" in this situation is not to compare who is more "authoritative," but to ask: what ultimate true meaning does this set of teachings point toward? Does it lead me toward "a state to be attained" (even a high-level state), or toward "the merging of subject and object, the permanence of dharma-nature"? Does it make me more dependent on the teacher as a person, or does it ultimately allow me to bear witness to dharma-nature independently of anyone? How does it describe "the Tathāgata" (or ultimate reality) — as impermanent and changing, or as permanent and unchanging?

Scenario Three: Choosing among teachings in family and intimate relationships

Your parents tell you "life is only complete if you marry and have children"; your friend tells you "not marrying and not having children is the real freedom"; one book tells you "intimate relationships are the practice ground of cultivation"; another book tells you "only by letting go of all relationships can you awaken."

Although these "teachings" are not Buddhist scriptures, the spirit of "rely on definitive meaning, not on provisional meaning" applies fully. The criterion is: which set of statements ultimately leads you toward deeper freedom and truth-as-it-is, rather than toward another, more refined form of attachment? The criterion also lies in this: does the person who says these things live in a state of "contentment and non-attachment," or in a state of "arrogance and self-importance, greedily seeking offerings and benefits"?

Scenario Four: How you react when facing statements like "all is empty" and "all is impermanent"

Someone reads the *Heart Sūtra*'s "all dharmas are empty in appearance" (諸法空相) and immediately falls into nihilism; someone hears a teacher say "all is impermanent" and immediately gives up all effort; someone seizes upon "selflessness" to evade responsibility.

This is precisely the trap the scripture itself points out: "all is burning, all is impermanent, all is suffering, all is empty, all is selfless" — if one cannot understand its meaning and grasps at it, one will trap nirvāṇa itself within these negating words. The attitude of definitive meaning is: when hearing "impermanence," know that this is spoken to overturn the view of permanence, not to make you take impermanence as a new permanence; when hearing "emptiness," know that this is spoken to overturn the view of substantial existence, not to make you take emptiness as a new substantiality. The tool of negation must not itself be made into the object that negation is meant to overturn.

Scenario Five: Reading the same scripture at different stages, with different "definitive/provisional" feelings

The same passage of scripture — when first read, you feel you understand it; a few years later you read it again and find it was not that at all; a teacher's teaching from ten years ago seems to contradict today's teaching, but on careful examination it is actually one layer deeper.

This confirms what the scriptures say about "rely on wisdom, not on consciousness" (依智不依識) — the same statement, read from the perspective of consciousness (discriminating mind), means one thing; read from the perspective of wisdom (direct observation of reality), means another. A truly definitive scripture is one that each time you read it, leads you toward deeper true meaning; a provisional scripture is one that only spins on the literal surface, forever cycling at the same level.

The places where people most commonly project wrongly:

1. Understanding "rely on scriptures of definitive meaning" as "pick the scriptures you like to read" — this turns reliance into preference, and the scriptures explicitly oppose this kind of "generating attachment toward the teachings spoken through appropriate skillful means" (隨宜方便所說法中 生執著). 2. Understanding "do not rely on scriptures of provisional meaning" as "the śrāvaka scriptures can be discarded" — the scriptures say "should not be relied upon" is said with respect to ultimate reliance, not with respect to transformative function. The śrāvaka teachings still have great use for those of corresponding faculties; it is only that those who have aroused the great mind should not take them as ultimate. 3. Treating this item as an "academic judgment question" — thinking that as long as one researches clearly which scripture is definitive meaning, that is enough. The scriptures explicitly say that "definitive meaning" also involves the practice states of "not feigning dignified conduct, not being arrogant and self-important, not greedily seeking offerings and benefits" — discernment and practice cannot be separated. 4. Equating "definitive meaning" with "profound" — the scriptures use the metaphors of "half-letters/full-letters" and "first plowing/fruit"; the key point is whether it is ultimate and complete, not whether the literal wording is difficult.


Why Contemporary People Need It

The principle of "rely on scriptures of definitive meaning, not on scriptures of provisional meaning" has at least four layers of urgent significance in the contemporary context:

First: The information age calls for the ability to discern authenticity and depth. Contemporary people encounter more information than an ancient person could hear in an entire lifetime, yet very little of it truly points to ultimate true meaning. Many people are led in by diluted concepts like "Buddha-style," "lying flat," and "mindfulness," without knowing their original direction. If no one teaches him to penetrate from "words" to "meaning," from "consciousness" to "wisdom," and to discern from "provisional meaning" to "definitive meaning," he can easily spend his whole life spinning within secondhand information, ultimately equating Buddhism with "chicken soup for the soul" or "Eastern mysticism."

Second: Breaking blind dependence on "authoritative figures" requires the criterion of the Dharma itself. The four reliances finally settle on "rely on the Dharma, not on the person," and "rely on scriptures of definitive meaning" is precisely the prelude to this step — only by first establishing what constitutes the teaching of ultimate true meaning can one avoid mistakenly choosing what to rely on because of a teacher's authority, number of followers, or eloquence. In an age where masters fill the sky and influencers fill the Dharma-realm, this respect for the Dharma itself is more urgent than in any other age.

Third: Avoiding the trap of "grasping at negations." The mistake contemporary Dharma practitioners most easily make is seizing upon statements like "impermanence," "selflessness," and "emptiness" as absolute truths, thereby negating nirvāṇa as well, and negating their own lives as well. This kind of attachment that "takes destruction as establishment" is precisely the modern version of what the scriptures explicitly warn against: "not understanding its meaning and grasping at it" (不能了其義而取著). The attitude of definitive meaning is to pass through the negation and arrive at the reality the negation points toward — this is precisely the training contemporary practitioners most lack.

Fourth: Rebuilding "contentment" (知足), a quality thoroughly dissolved by contemporary life. The scriptures interpret "definitive meaning" as "contentment" — not feigning dignified conduct, not being arrogant and self-important, not greedily seeking offerings and benefits. The core driving force of contemporary life is precisely the opposite of contentment: pursuing more attention, higher status, more refined lifestyles. The spirit of definitive meaning requires the practitioner to possess an inner sufficiency and vigilance — this quality is the psychological foundation for truly entering ultimate true meaning.

On a deeper level, "rely on scriptures of definitive meaning, not on scriptures of provisional meaning" is in fact a commitment to ultimate reality: I believe there is a real, verifiable dharma-nature, and my reliance must run all the way through to it, rather than stopping at any intermediate station. This commitment is the fundamental watershed between the bodhisattva path and the śrāvaka path, between self-benefiting practice and benefiting others, between worldly goodness and supramundane liberation.


Common Misreadings and Clarifications

Misreading One: "Rely on scriptures of definitive meaning" equals "only read Mahāyāna scriptures, do not read śrāvaka scriptures."

This is the most common misreading. The scriptures explicitly state that "the Tathāgata, for the sake of liberating sentient beings, teaches the śrāvaka vehicle through skillful means" — the śrāvaka teachings have a genuine transformative function and still have great use for those of corresponding faculties (such as beginners whose compassion is not yet vast and whose wisdom is not yet deep). "Should not be relied upon" is said with respect to the bodhisattva's ultimate reliance — bodhisattvas who have aroused the great mind and practice the great conduct should take the Mahāyāna definitive meaning as their reliance, rather than taking the śrāvaka teachings as their ultimate destination. Reading "should not be relied upon" as "should be discarded" is taking the text out of context.

Misreading Two: "Definitive meaning" equals "literally profound and difficult to understand."

The scriptures use "half-letters/full-letters" and "first plowing/fruit" as metaphors; the key to whether something is definitive meaning is whether it is ultimate and complete, not whether the literal wording is difficult. The *Amitābha-sūtra* (《阿彌陀經》) is easy to read literally, but for those of corresponding faculties its direction is extremely ultimate; the "parable of the poor son" (窮子喻) in the *Lotus Sūtra* (《法華經》) is literally a story, yet its degree of definitive meaning is extremely high. Difficulty is a matter of the sequence of practice; definitiveness is a matter of ultimacy. The two must not be conflated.

Misreading Three: "Rely on scriptures of definitive meaning" is the business of scholars, unrelated to actual practice.

After explaining the multiple layers of meaning of "definitive meaning," the scriptures specifically interpret "definitive meaning" as "contentment" — a state of practice. Judging whether a scripture is definitive meaning is not merely a textual analysis problem; it is also a self-examination question for the practitioner: when I read this scripture, am I pursuing the accumulation of knowledge, or am I allowing my arrogance, craving, and attachment to loosen layer by layer? After reading it, do I depend more on this scripture and the person who teaches it, or am I more able to bear witness independently to dharma-nature? These three points are precisely the content listed in the scriptures' definition of "definitive meaning."

Misreading Four: "All is impermanent, suffering, empty, selfless" is itself definitive meaning.

This is the trap the scriptures specifically warn against. The *Mahāparinirvāṇa-sūtra* explicitly says that if one cannot understand their meaning and grasps at them, one will then interpret nirvāṇa itself as burning and impermanent, and likewise apply suffering, emptiness, and selflessness to it. The function of negating statements is to break attachment, not to establish a new absolute truth. Grasping at the negating statements themselves is a more hidden form of attachment. The attitude of definitive meaning is to use these statements to break the two attachments to self and dharmas, but not to turn these statements into a new attachment to self and dharmas.

Misreading Five: "Rely on scriptures of definitive meaning" can stand alone apart from "rely on the meaning," "rely on wisdom," and "rely on the Dharma."

The four reliances are a complete system. Taking only "rely on scriptures of definitive meaning" in isolation easily falls into the cycle of "judging scriptures by scriptures, judging authorities by authorities." One must first possess the ability of "rely on the meaning, not on the words" (being able to penetrate from words to true meaning), then the ability of "rely on wisdom, not on consciousness" (being able to penetrate from discriminating mind to direct observation of reality), before one can truly discern what definitive meaning is; after discerning definitive meaning, "rely on the Dharma, not on the person" can become stable — not mistaking provisional meaning for definitive meaning because of a teacher's fame. Splitting the four items and taking only one is the most typical misreading of the four reliances.

Misreading Six: "Do not rely on scriptures of provisional meaning" means one must judge which scriptures are definitive meaning and which are not.

This degrades the bodhisattva's practice into a scholar's textual research. The original intention of the scriptures is to let the practitioner establish the direction of one's own reliance — I take the Mahāyāna definitive meaning as my ultimate reliance, rather than remaining at the stage of śrāvaka skillful means. This is an inner orientation, not an external judgment. To judge the śrāvaka scriptures as "not counting" from the position of a bodhisattva is itself arrogance and self-importance — precisely the content the scriptures list as marks of provisional meaning.


*The "rely on scriptures of definitive meaning, not on scriptures of provisional meaning" among the bodhisattva's four reliances is, on the surface, a multiple-choice question about which scripture to read; at its core, it is a question of commitment about "what you are willing to entrust your life to." It requires the practitioner to possess three kinds of penetrating power: penetrating from words to meaning, from consciousness to wisdom, and from provisional meaning to definitive meaning. When these three penetrating powers become habitual, the vast ocean of scriptures is no longer a flood in which one drowns, but clear signposts pointing toward ultimate dharma-nature.*

定义与核心要义

依了义经不依不了义经,梵语 nītārtha-sūtra-pratisaraṇa,为菩萨摩诃萨四依法之第三项,指修行者于经教之取舍准则:依止阐说究竟实义之经典,不依止未了究竟之经典。此项与依义不依语、依智不依识、依法不依人并列,以「语义、智识、经义、法人」之四重对辨,构成菩萨于教法与修行上之依止准则。

主要阐述

《大方等大集经》两处提及此准则。第一处以简列方式标示其为「陀罗尼璎珞庄严」所摄菩萨修行项目之一,与「依智不依于识」、「依法不依于人」、「依出世不依于世」并列。第二处则于舍利弗请法段落中正式开展「菩萨摩诃萨四依法亦不可尽」之论述。然而此经对第三依未作独立详细解说,仅以「是名依了义经、不依不了义经」一句作结,旋即转入第四依「依法不依于人」之阐释,后者详辨「人」之摄取人见与「法性」之不变不易、无作非作、无住不住、一切平等。

《大般涅槃经(南本)》对此概念有较为详细之展开。其初层界定以乘为判:声闻乘名不了义,无上大乘乃名了义。理由是:声闻闻如来「深密藏处」而生疑怪,不知此藏出于大智海,如婴儿无所别知;菩萨则有真实智慧,能随其自心,以无碍大智如大人般无所不知。

在具体命题上,此经以如来常与无常辨别二种经教:说「如来无常、变易」、如来为食所长养、或如来入涅槃如薪尽火灭,皆名不了义;说「如来常住不变」、如来入于法性,则名了义。又分别说「声闻所说应证知者」名不了义,「菩萨所说应证知者」名了义。

此经以教化次第说明声闻乘何以不应依:如来为度众生以方便力说声闻乘,譬如长者教子「半字」,又如初耕而未得果实,故名不了义;大乘法应依止,名为了义。此处之判准并非否认方便说之教化作用,而是明定在依止时应依大乘之了义。

「了义」又被解作「知足」:不诈现威仪清白,不憍慢自高,不贪求利养,不于如来随宜方便所说法中生执着,能住于此即已住第一义。因此了义不只涉及经句内容,也涉及能否辨识方便、避免取着及相应之行持状态。

对「一切烧燃、一切无常、一切皆苦、一切皆空、一切无我」等语,此经称为不了义,理由在于若不能了其义而取着,便会把涅槃也解作烧燃、无常,并同样套用苦、空、无我。故问题不只在字面,而在是否了达语句所指,避免将概括之说错误施于涅槃。

不同部类与译本的表述差异

就术语而言,《大方等大集经》与《大般涅槃经(南本)》皆使用「了义经」、「不了义经」之标准译名,未见特殊变体。两经在解说详略上有显著差异:《大方等大集经》仅以结语形式标定其名,未展开独立解说;《大般涅槃经(南本)》则从乘之判别、命题之辨识、教化之次第、行持之状态等多层次加以阐发。

两经在四依之先后排列上亦微有不同:《大方等大集经》第一处简列中以「依了义经不依不了义经」列为第二项(于「二者」至「五者」之间依次列举四项);第二处详论中则作为四依之第三项。《大般涅槃经(南本)》固定列为四依之第三项。

两经所列四依之具体名相亦有出入:《大方等大集经》第二处四依为「依义不依语、依智不依识、依了义经不依不了义经、依法不依人」;《大般涅槃经(南本)》所列为「依法不依人、依义不依语、依智不依识、依了义经不依不了义经」,四项内容一致但首项「依法不依人」置于首位。

与相关概念的关系

此概念与四依中其他三项密不可分:前承「依义不依语」之语义对辨、「依智不依识」之智识对辨,后启「依法不依人」之法人对辨。在《大般涅槃经(南本)》中,迦叶先总说四法应当「证知」,不应仅凭四种人的身分而依止;将「依法」释为依如来大般涅槃、法性与常住不变的如来,若说如来无常变易即是不知不见法性,不应依止,使「依了义经」与法性、如来常住等判准相互贯通。经末又以四依总摄戒律、阿毘昙、修多罗,说若不违四依亦应依止,若有相违则相应部分不应依,明定四依为辨别一切经教是否可依之准则。

代表性原文引用

《大方等大集经》:「二者依智不依于识,三者依了义经不依不了义经,四者依法不依于人……舍利弗!是名菩萨摩诃萨四依无尽。」

《大般涅槃经(南本)》:「声闻乘名不了义;无上大乘乃名了义。」「说如来常住不变、如来入于法性者,是名了义;说如来无常变易、如来入涅槃如薪尽火灭者,是名不了义。」「了义者,了达一切大乘经典。」

大般涅槃經(南本)T0375 · 涅槃部

《大般涅槃經(南本)》先由迦葉重申「依法不依人、依義不依語、依智不依識、依了義經不依不了義經」四法,並說四法應當「證知」,不應僅憑四種人的身分而依止。經中將「依法」釋為依如來大般涅槃、法性與常住不變的如來;若說如來無常、變易,即是不知不見法性,不應依止。這使「依了義經」置於整體四依之中,與法性、如來常住等判準相互貫通。

本經直接以「依了義經、不依不了義經」為固定術語。其初層界定是:不了義指聲聞乘;聲聞聞如來「深密藏處」而生疑怪,不知此藏出於大智海,如嬰兒無所別知。了義則指「菩薩真實智慧」,能隨其自心,以無礙大智如大人般無所不知。因此,本經又明言「聲聞乘名不了義;無上大乘乃名了義」,以聲聞乘與無上大乘作成對判別。

在具體命題上,本經以如來之常與無常辨別了義、不了義:說「如來無常、變易」、如來為食所長養,或如來入涅槃如薪盡火滅,皆名不了義;說「如來常住不變」、如來入於法性,則名了義。經文亦分別說「聲聞所說應證知者」名不了義,「菩薩所說應證知者」名了義。此處本經所用的特色語彙是「如來入法性」,並以「常住、不變易」表述了義所顯之如來。

本經進一步以教化次第說明聲聞乘何以不應依:如來為度眾生,以方便力說聲聞乘,譬如長者教子「半字」,又如初耕而未得果實,故名不了義;大乘之法則應依止,名為了義。這裡的判準不是否認方便說的教化作用,而是明定在依止時應依大乘之了義。

「了義」又被解作「知足」:不詐現威儀、清白,不憍慢自高,不貪求利養,且不於如來隨宜方便所說法中生執著;能住於此,即已住第一義。因此,了義不只涉及經句內容,也涉及能否辨識方便、避免取著及相應的行持狀態。

對「一切燒燃、一切無常、一切皆苦、一切皆空、一切無我」等語,本經稱為不了義,理由在於若不能了其義而取著,便會把涅槃也解作燒燃、無常,並同樣套用苦、空、無我。故問題不只在字面,而在是否了達語句所指,避免將概括之說錯誤施於涅槃。

最後,本經總攝四依,說戒律、阿毘曇、修多羅若不違四依,亦應依止;若其中有與四依相違之說,則相應部分不應依。經末以「了義者,了達一切大乘經典」作結,明確把了義的最終表述落在對一切大乘經典的了達,並以四依作為辨別經教是否可依的準則。

大方等大集經T0397 · 大集部

《大方等大集經》對於「依了義經不依不了義經」之闡述,散見於不同脈絡,皆與菩薩所應依止之教法準則相關。

第一處見於陀羅尼瓔珞莊嚴之列舉文中。此段以層遞方式臚列菩薩所修之法,於「二者」至「五者」之間,依次列舉「依智不依於識」、「依了義經不依不了義經」、「依法不依於人」、「依出世不依於世」四項依止準則,再接「六種」乃至「十種」之語言功德,總名為「陀羅尼瓔珞莊嚴」。此處以簡列方式將「依了義經不依不了義經」標示為菩薩修行之依止準則之一。

第二處見於舍利弗請法之段落,緊接「菩薩摩訶薩四無礙智」之後,正式開展「菩薩摩訶薩四依法亦不可盡」之詳細論述。經中明列四依為:一、依義不依語;二、依智不依識;三、依了義經不依不了義經;四、依法不依人。經文以「亦不可盡」強調此四依之無盡功德。

在四依之詳細解說中,此經以「語」與「義」之對照為主要說理方式,逐一臚列布施調伏、持戒、忍辱、精進、禪定、智慧等修行項目,說明「語」為世法文字之相,「義」為出世無文字之實。及至第三依之末,經文以「是名依了義經、不依不了義經」一句作結,明確標示其名。

值得注意的是,此經未對「依了義經不依不了義經」獨立展開與「依義不依語」同等詳細之逐項解說,而是以結語形式標定其名,旋即轉入第四依「依法不依於人」之闡釋。後者詳辨「人」之攝取人見與「法性」之不變不易、無作非作、無住不住、一切平等,強調「若有攝取如是見者,是謂依人」,故當「依一切法、不依於人」;結尾以「舍利弗!是名菩薩摩訶薩四依無盡」作總收束。

由上述兩處脈絡可知,此經將「依了義經不依不了義經」定位為菩薩摩訶薩四依法之第三項,前承依義依智之判別,後啟依法不依人之歸趣,整體以「語義、智識、經義、法人」之四重對辨,構成菩薩於教法與修行上之依止準則。所用術語「了義經」、「不了義經」屬標準譯名,未見特殊變體;本經亦未對此概念作獨立判釋,而是將其嵌於四依整體架構中呈現。
