What This Concept Means

In the early Buddhist context of the Āgama scriptures, 具足 (saṃpanna, "complete endowment") is by no means a vague general adjective, nor is it what moderns call "perfection" or "satisfaction." Its underlying meaning is the state of being complete, full, sufficient, and lacking nothing.

If the path of liberation is compared to a tall building under construction, then 具足 (saṃpanna) is at once the qualification and framework for entering the construction site, the strict acceptance standard for each floor of work (precepts, concentration, wisdom), and the final state of the entire building upon completion.

In the classical scriptures (such as the *Madhyama-āgama* (《中阿含經》) and the *Saṃyuktāgama* (《雜阿含經》)), 具足 (saṃpanna) unfolds in four clear and rigorous layers:

``` ┌─ 1. Institutional & identity fulfillment (upasaṃpanna: the complete precept-body & eligibility to be a bhikṣu/bhikṣuṇī) ├─ 2. Fulfillment in precepts, concentration, wisdom & realization (three trainings complete, pure precepts complete, vidyā-caraṇa complete) 【 具足 (saṃpanna) 】─┤ ├─ 3. Fulfillment in teaching & doctrine (the complete true Dharma—good in the beginning, middle, and end, with meaning and text) └─ 4. Fulfillment in specific virtues & abilities (rūpa-saṃpanna: explaining Dharma & Vinaya; bodily-form fulfillment: renown & offerings of requisites) ```

1. Institutional & Identity Fulfillment: 受具足 (upasaṃpanna, "Receiving Full Ordination — Ordination & Commitment")

In the saṅgha system, the most direct expression of 具足 (saṃpanna) is 受具足 (upasaṃpanna, "receiving the full precepts" — accepting the complete bhikṣu or bhikṣuṇī precepts), through which one formally obtains the status of a saṅgha member.

* The decisive prerequisite: Going forth to receive full ordination is not a momentary impulse. The *Madhyama-āgama* records that Rāṣṭrapāla (賴吒惒羅), the householder's son, when requesting the Buddha to allow him to go forth and receive full ordination, was clearly told by the Buddha: if one has not obtained parental permission, one must never be allowed to go forth, nor given full ordination [3717]. Only after settling and properly ordering one's worldly ethical relationships, and when the Buddha or the saṅgha confers it according to the rules, is 受具足 (upasaṃpanna) considered complete [2871, 3719, 4829]. * The discipline of the monastic code: For women, receiving full ordination must be predicated on observing the 八尊師法 (aṣṭa-gurudharma, "the eight weighty rules"), e.g., the first weighty rule stipulates that "a bhikṣuṇī should seek full ordination from a bhikṣu," and the eighth stipulates that even a bhikṣuṇī ordained for a hundred years should respectfully pay homage to a bhikṣu who has just received full ordination [3575, 3576]. * The gateway to the path of liberation: Receiving full ordination is not the endpoint, but the starting point of "dwelling far apart, with a mind not given to negligence, diligently cultivating effort" (遠離獨住,心無放逸,修行精勤), and the necessary support for progressing toward the attainment of the arhat (阿羅漢/阿羅訶, arahant) fruition [3719, 9052].

2. Fulfillment in Precepts, Concentration, and Wisdom: The Three Trainings and Virtuous Attainment (Spiritual Mastery)

After crossing the institutional threshold, 具足 (saṃpanna) penetrates into every link of inner cultivation:

* 三學具足 (triśikṣā, "the three trainings fulfilled"): Diligently striving in the three dharmas of 增上戒 (adhiśīla, "higher precepts"), 增上心 (adhicitta, "higher mind," i.e., concentration), and 增上慧 (adhiprajñā, "higher wisdom"), guarding the sense faculties [7866]. * 一切戒/淨戒具足 (all precepts / pure precepts fulfilled): The thorough purity of conduct and ethics. The scriptures praise: "pure precepts fully complete, right mindfulness always tranquil" (淨戒悉具足,正念常寂靜). Only through the dual cultivation of pure precepts and wisdom can one cross the flood of birth-and-death that is so hard to ford, without being tainted by the five desires [16766, 18981]. * 明行具足 (vidyā-caraṇa-saṃpanna, "knowing-and-acting fulfilled"): The Buddha is called the one "fully endowed with knowing and acting" (明行悉具足), meaning that the highest liberating wisdom (明, vidyā) and the most solid ethical practice (行, caraṇa) are completely fused with each other, with no tear between "knowing is easy, acting is hard" [7866, 18939].

3. Fulfillment in Teaching and Doctrine: The Perfection of the True Dharma (Doctrinal Integrity)

The *Madhyama-āgama* uses 具足 (saṃpanna) to describe the Dharma proclaimed by the Buddha — "good in the beginning, good in the middle, and good in the end, with meaning and with text, complete and pure, revealing the holy life" (初妙、中妙、竟亦妙,有義有文,具足清淨,顯現梵行) [3716]. This means that the true Dharma is complete and flawless in its logical system, practical path, textual expression, and ultimate direction (the holy life, 梵行, brahmacariya), requiring no admixture of worldly impurities and containing no fatal loopholes.

4. Unique Definitions in Specific Contexts: 色具足 (rūpa-saṃpanna) and 形體具足 (Specialized SA Definitions)

The *Saṃyuktāgama* gives several highly distinctive definitions that must never be read according to their literal face value:

* 色具足 (rūpa-saṃpanna): Here it by no means refers to handsome features or a good-looking face, but rather: if a person can answer questions concerning 阿毘曇 (abhidharma, "the higher Dharma / treatises") and 毘尼 (vinaya, "the discipline"), and explain them clearly, this is called 色具足 [8050]. * 形體具足 (bodily-form fulfillment): Here it likewise does not mean a tall or muscular physique, but rather that a good man or person of standing possesses widespread renown and virtue (名聞大德), such that offerings of wealth, clothing, food, bedding, and medicine naturally come to him [8048, 8050]. * 捷疾具足 (swiftness fulfillment): The ability of quick wisdom and rapid comprehension. These three together constitute the complete display of practical and teaching ability [8048, 8050].


Walking Through It in Daily Life

To clarify how 具足 (saṃpanna) maps onto life, we can follow a contemporary person's experience in work, study, and self-cultivation, walking through the concept layer by layer, while pinpointing the most easily confused points:

Scene One: Leaving a Job and Entering a New Track (Mapping to 受具足 and Its Preconditions)

* Contemporary experience: You want to leave an environment that drains you and commit to a long-term endeavor requiring full devotion (such as starting a business, pursuing advanced study, or a minimalist lifestyle). You cannot just "think" about it in your head; you must complete the formal procedures, sign the contract, and define rights and responsibilities. * Concept mapping: This is 受具足 (upasaṃpanna). It is not merely a psychological decision, but a formal establishment of identity and construction of boundaries. * Common error: Many people think 受具足 (upasaṃpanna) is just a formalistic ritual. The classical scriptures emphasize that before receiving full ordination, one must first obtain parental permission [3717]. Mapped onto life: a "rupture" that does not handle basic social responsibilities and interpersonal entanglements is mere escapism, not 受具足 (upasaṃpanna). The precondition for 具足 (saṃpanna) is the clarification of real relationships and the making of a commitment.

Scene Two: The Workplace Expert and Legal Counsel (Mapping to 色具足 and 捷疾具足)

* Contemporary experience: The team encounters a complex compliance and structural problem, and everyone is at a loss. A senior expert walks in, not only instantly perceiving the core of the problem (捷疾, "swift"), but also explaining the underlying framework, the operational rules (律, vinaya), and the underlying logic (勝法, "the higher Dharma") with crystal clarity, resolving all doubts on the spot. * Concept mapping: This is the 色具足 (rūpa-saṃpanna) and 捷疾具足 (swiftness fulfillment) defined in the *Saṃyuktāgama* [8048, 8050]. * Common error (the most frequent misreading): People commonly map 色 (rūpa) onto "good looks" or "physical appearance." But in this specific context of the Āgamas, 色具足 (rūpa-saṃpanna) is the systematic expository ability to provide clear answers concerning the rules (毘尼, vinaya) and the analytical method (阿毘曇, abhidharma) [8050].

Scene Three: The Natural Flow of Resources Brought by Virtue (Mapping to 形體具足)

* Contemporary experience: A wise person deeply rooted in their field never markets themselves online, never deliberately flatters or curries favor, yet whenever they launch a project, funds, venues, talent, and all kinds of support (requisites) flow in from all directions without cease. * Concept mapping: This is 形體具足 (bodily-form fulfillment) — through noble virtue and far-spreading renown (名聞大德), one naturally attracts the necessary life and career requisites (財利, wealth; 臥具, bedding; 湯藥, medicine, etc.) [8048, 8050]. * Common error: People easily mis-map 形體具足 (bodily-form fulfillment) onto "a tall, muscular build." In the scriptures, it refers to the gravitational effect of moral reputation and the material security it provides.

Scene Four: Unity of Knowing and Doing, and Emotional Stability (Mapping to 三學具足 and 明行具足)

* Contemporary experience: You have read countless psychology and philosophy books (明, knowing), yet the moment a colleague clashes with you, you still explode in anger (lacking 增上心, higher mind, and 淨戒, pure precepts). True transformation is: you have a bottom line in your conduct (戒具足, precepts fulfilled), you can maintain composure amid emotional waves (增上心具足, higher mind fulfilled), and you clearly see the impermanence and non-self of anger (智慧具足, wisdom fulfilled). * Concept mapping: This is 三學具足 (the three trainings fulfilled) and 明行具足 (vidyā-caraṇa-saṃpanna, "knowing-and-acting fulfilled") [7866, 18939]. * Common error: Treating "understanding the principle" as 具足 (saṃpanna). In the classical definition, if there is only cognition (明) without purity of conduct and concentration (行), it cannot be called 具足 (saṃpanna) at all.


Why Contemporary People Need It

The spiritual crisis of contemporary people is essentially a crisis of "fragmentation" (碎片化) and "sandwiching" (夾心化) — being caught in the middle.

We live in an era that tolerates "half-hearted" existence: you can study Buddhism and do yoga while binge-drinking and spiraling into anxiety late at night; you can master the most cutting-edge AI tools (an extremely developed 捷疾, "swiftness"), yet have no ethical bottom line in interpersonal dealings; you can speak in lofty technical terms, yet emotionally collapse in an instant when a sudden crisis hits.

The reason contemporary people need 具足 (saṃpanna) is that it provides a complete structure of liberation that refuses a "collage-style existence" (拼貼式生存):

1. Breaking the "à la carte spirituality" (自助餐式修行) pattern

Contemporary people like to treat spiritual life like a buffet: taking only the relaxation of meditation, not the constraints of precepts; taking only the coolness of wisdom, not the tedium of cultivating concentration. The 三學具足 (triśikṣā, "three trainings fulfilled") of the Āgamas reminds us: liberation is an ecosystem. Without the protection of 增上戒 (adhiśīla, higher precepts), concentration is a castle on the sand; without the stillness of 增上心 (adhicitta, higher mind), wisdom degenerates into a completely useless skill of argument.

2. From "information abundance" in the era of AI tools to "knowing-and-acting fulfilled" (明行具足)

In the contemporary era, AI technologies such as large language models can effortlessly answer questions about doctrinal terms and even imitate perfectly polished logical expositions. Science and algorithms process information far more efficiently than humans, but this precisely throws into relief the limitations and the opportunity of human life: * The limitation of science and AI: AI can possess an extremely powerful 色具足 (rūpa-saṃpanna, the ability to answer questions about rules and systems), but it has no embodied experience, no volitional karma (意志造作), and cannot accomplish 淨戒具足 (pure precepts fulfilled) or 心善解脫 (the mind's good liberation). * The reshaping of life: The concept of 具足 (saṃpanna) reminds contemporary people that true knowledge is not data stored in the brain or on servers, but must be transformed, through the cultivation of the three karmic gates of body, speech, and mind (身、口、意三業), into the action (行) and liberated state of your individual life.

3. Providing a true sense of security beyond "worldly success"

Secular society teaches us to pursue wealth, fame, and status, but this often brings ever-deeper anxiety over gain and loss (患得患失). The 形體具足 (bodily-form fulfillment) and 三學具足 (three trainings fulfilled) of the scriptures tell us: true sufficiency (具足, saṃpanna) is not external plunder and accumulation, but the natural appearance of life's resources and spiritual peace once inner virtue is abundant.


Common Misreadings and Clarifications

Misreading One: Equating 具足 with worldly "perfectionism"

* Clarification: Worldly perfectionism is based on the ego's desire for control, wanting everything in the world to conform to one's expectations, and it often brings deep anxiety; Buddhist 具足 (saṃpanna), by contrast, refers to the absence of deficiency and leakage (無漏) in the cultivation path and inner virtue. It does not require you to be proficient in every worldly skill, but requires that you leave no fatal moral or cognitive loopholes on the path of liberation.

Misreading Two: Reading 色具足 and 形體具足 literally

* Clarification: As repeatedly emphasized above, in the specific context of *Saṃyuktāgama* sūtra no. 8050: * 色具足 (rūpa-saṃpanna) ≠ good looks, but rather the dharma-ability to give clear explanations of 阿毘曇 (abhidharma, treatises) and 毘尼 (vinaya, discipline) [8050]. * 形體具足 (bodily-form fulfillment) ≠ a fit body, but rather the state of possessing widespread renown and virtue (名聞大德), naturally attracting offerings of clothing, food, bedding, and the like [8048, 8050]. These distinctive technical definitions must never be read through the literal meaning of modern Chinese.

Misreading Three: Thinking 受具足 is merely a formalized religious ritual unrelated to liberation

* Clarification: Some people think, "as long as the mind is good, why bother receiving precepts, leaving home, and getting ordained?" But in the Āgamas, receiving full ordination (受具足, upasaṃpanna) is the core contract that establishes the cultivation environment of "dwelling far apart, with a mind not given to negligence" (遠離獨住,心無放逸) [3719]. Without the protection of institutional structure and the precept-body, an individual's practice easily collapses amid the five desires of the world. Receiving full ordination is an extremely serious dividing line between worldly life and the holy life (梵行, brahmacariya).

Misreading Four: Splitting 明行具足 apart, thinking that understanding the theory equals completing the practice

* Clarification: Many contemporary people equate "reading and understanding the scriptures" with "attaining liberation." The scriptures call the Buddha and the arhats "fully endowed with knowing and acting" (明行悉具足) [7866, 18939], precisely to emphasize that 明 (pure cognition) and 行 (pure practice, precepts, and concentration) are both indispensable. With only 明 and no 行, it is mere empty talk; with only 行 and no 明, it is blind practice. Only when the two are completely and perfectly fused can one truly be called 具足 (saṃpanna).

Canonical EntryAI-generated

一、定义与核心要义 「具足」(梵语:sampanna)在阿含经典中是一个多义且核心的佛教概念。其首要含义是指制度上的「受具足」,即出家修行者通过特定仪式接受完整的戒律,正式取得僧伽成员的身份;其次,它广泛用于形容修行德行、戒定慧三学、佛陀所说之法的圆满无缺;此外,在特定语境下,它还被赋予了关于法义解答能力与名闻利养等世俗与法义特质的独特定义。 ### 二、主要阐述 1. 僧伽制度中的「受具足」 在出家修行者的制度与身份认定上,「具足」特指接受完整的比丘或比丘尼戒。在《中阿含经》中,凡欲出家作比丘、修持梵行者,皆须经历「受具足」的过程。这一过程有着严格的前提条件,其中最核心的是必须获得父母的允许。如赖吒惒罗居士子向佛陀请求出家受具足时,佛陀明确告知,若无父母听许,则「不得度汝出家學道,亦不得受具足」。只有在父母最终同意后,佛陀才为其「授其具足」。受具足是由佛陀或过去佛(如迦叶如来)亲自或依轨则授与,如优多罗童子请求迦叶如来「授與具足,得作比丘」;异学鞞摩那修在见法后亦请求「受具足,得比丘,行梵行」,并随即获得佛陀授与。 在《杂阿含经》中,同样多次出现「出家、受具足」或「受具足,成比丘分」的表述。例如,外道婆蹉在正法律中求出家并「受具足」,在半月内便悉知悉证如来正法;外道须跋陀罗亦是在正法律中「出家、受具足」,最终证得阿罗汉;佛陀慈悲度化他人时,亦常以「出家受具足」作为接引。 对于女性出家,本经详细记载了佛陀为女人设施的「八尊师法」,这是女人「得受具足,作比丘尼」的先决条件。其中第一尊师法明确规定「比丘尼當從比丘求受具足」;第八尊师法规定「比丘尼受具足雖至百歲,故當向始受具足比丘極下意稽首作禮,恭敬承事,叉手問訊」。这表明在受具足的法腊上,比丘尼与比丘之间存在着严格的礼敬规范。 2. 戒定慧三学与解脱德行的具足 除了制度上的受戒,经典更强调修行者必须在戒、定、慧等多个层面上达到圆满具足,才能走向最终的解脱。在《杂阿含经》中,这一维度的论述极为丰富: 首先是「三学具足」,经中指出「三學具足者,是比丘正行」,即在增上戒、增上心、增上慧这三法上勤勉精进,常守护诸根,从而心善解脱。其次是「一切戒/净戒具足」,经中反复赞叹「一切戒具足,智慧善正受」或「淨戒悉具足,正念常寂靜」的境界,认为具足净戒与智慧者,能够内思惟正念,度过难以度脱的生死洪流,不染五欲,超度色爱。此外,还有「明行/明达具足」,佛陀被称为「明行悉具足」者,经中亦使用「明達善具足」或「明達悉具足」来描述正行已清净、诸漏已尽、不复受后有的圣者状态。 3. 色具足与形体具足的独特定义 《杂阿含经》对「色具足」和「形體具足」给出了非常具体的、具有该经特色的定义。其中,「色具足」是指若有人能够解答关于「阿毘曇」(阿毗达磨)和「毘尼」(律)的提问,并为其解说;而「形體具足」则是指善男子或士夫拥有名闻大德,能够感得财利、卧具、汤药及各种生活资具的供养。这两者与「捷疾具足」共同构成了「捷疾具足、色具足、形體具足」的完整表述。 ### 三、不同部类与译本的表述差异 1. 戒律术语的差异:在《中阿含经》中,并未使用后期常见的「具足戒」一词,而是统一使用「受具足」或「授與具足」来指代受戒仪式与资格的取得;而在《杂阿含经》中,同样使用「出家、受具足」或「受具足,成比丘分」。 2. 圣者果位译名:在《中阿含经》中,比丘受具足后精勤修行所证的最终果位被译为「阿羅訶」;而在《杂阿含经》中,则译为「阿羅漢」。 3. 德行描述的用词:《杂阿含经》中对圣者智慧与德行的具足有多种表述,如「明行悉具足」、「明達善具足」或「明達悉具足」,展现了该经在描述解脱境界时的丰富用词。 4. 佛法的圆满:除了僧伽戒律的「受具足」外,《中阿含经》还以「具足」形容佛陀所宣说之法,称其「初妙、中妙、竟亦妙,有義有文,具足清淨,顯現梵行」,此处的「具足」意指佛法在义理与文字上的圆满与充足。 ### 四、与相关概念的关系 1. 与「阿罗汉/阿罗诃」的关系:受具足是证得阿罗汉果的前提与起点。比丘在「受具足已」,需「在遠離獨住,心無放逸,修行精懃」,最终才能证得「阿羅訶」或「阿羅漢」果位。 2. 与「八尊师法」的关系:在女性出家制度中,「受具足」与「八尊师法」紧密相连。八尊师法规定了比丘尼受具足的途径(从比丘求受)以及受具足后的礼敬规范,是女性得以受具足、作比丘尼的先决条件。 3. 与「三学/净戒」的关系:制度上的「受具足」需转化为修行上的「三学具足」与「一切戒具足」。修行者唯有在增上戒、增上心、增上慧上圆满,才能达到真正的解脱。 ### 五、代表性原文引用 1. 《中阿含经》卷三十四:「若父母不聽汝於正法、律中至信、捨家、無家、學道者,我不得度汝出家學道,亦不得受具足。」 2. 《中阿含经》卷三十四:「初妙、中妙、竟亦妙,有義有文,具足清淨,顯現梵行」。 3. 《杂阿含经》卷二十八:「三學具足者,是比丘正行」。 4. 《杂阿含经》卷二十九:「云何色具足?若有問阿毘曇、毘尼,能答、能解,是名色具足。云何形體具足?若有善男子、士夫,名聞大德,得財利、衣被、飲食、臥具、湯藥,是名形體具足。」

中阿含經T0026 · 阿含部

《中阿含經》以「具足」為受戒得比丘(比丘尼)資格的專術語,核心句式為「出家學道,受於具足,得作比丘」,授戒一方則稱「授與具足」「授其具足」,尼眾則作「得受具足,作比丘尼」。全經所見用例皆以此動賓結構(受/授+具足)表達 upasaṃpadā(近圓、大戒)之義,不另立「近圓」「大戒」等異名,亦不與形容詞義的「具足」(圓滿完備)混用——後者僅見於讚佛說法「有義有文,具足清淨,顯現梵行」一類修飾語境。

一、受具足為出家成比丘之必要環節。優多羅童子問難提波羅:「我可得從迦葉如來、無所著、等正覺出家學道,受於具足,得作比丘,行梵行耶?」難提波羅轉白佛已,佛「默然而受」,隨後「度優多羅童子出家學道,授與具足」。賴吒惒羅居士子亦三請父母,得聽許後白佛:「願得從世尊出家學道而受具足,得作比丘」,佛即「度賴吒惒羅居士子出家學道,授其具足」。異學鞞摩那修見法後白佛:「願得從佛出家學道,受具足,得比丘,行梵行」,佛言「善哉!比丘!行梵行也」,「即受具足,得比丘」。三例句式高度一致,顯示本經以此為固定敘事程式。

二、父母聽許為受具足之前置條件。佛明告賴吒惒羅:「若父母不聽汝於正法、律中至信、捨家、無家、學道者,我不得度汝出家學道,亦不得受具足。」 未得親許則佛不授戒,此為本經獨特意涵。

三、比丘尼受具足須依比丘僧。佛為女人施設八尊師法,第一法即:「比丘尼當從比丘求受具足」;第八法規定:「比丘尼受具足雖至百歲,故當向始受具足比丘極下意稽首作禮,恭敬承事,叉手問訊」。佛總結:「若瞿曇彌大愛奉持此八尊師法者,是此正法、律中,出家學道,得受具足,作比丘尼」。瞿曇彌大愛頂受八法後,「於正法、律中,出家學道,得受具足,作比丘尼」,其後「轉成大比丘尼眾」。是知本經中尼眾具足必由比丘僧授予,且以八尊師法為得戒前提。

四、受具足後之修道證果。賴吒惒羅「受具足已,在遠離獨住,心無放逸,修行精懃」,乃至「生已盡,梵行已立,所作已辦,不更受有」,得阿羅訶。鞞摩那修「出家學道,受具足已,知法見法,乃至得阿羅訶」。本經敘事以「受具足」為凡聖轉折之節點,受戒後即入修道證果之歷程。

綜上,《中阿含經》「具足」一詞專指受大戒、得比丘(尼)資格,術語形式固定為「受(於)具足/授與(其)具足/得受具足」,不採他譯異名;其論述重心在受戒因緣(父母聽許、八尊師法)與受戒後之梵行證果。

雜阿含經T0099 · 阿含部

《雜阿含經》中「具足」一詞承擔兩組語義,一為「圓滿具備某種功德條件」,二為「受具足」即受比丘(比丘尼)大戒之專稱,二者並行而語境分明。

一、三具足:捷疾、色、形體

經中以「捷疾具足、色具足、形體具足」三事並舉,作為衡量善男子(或士夫)修行與福德是否圓滿的框架。其中「色具足」指能為人解說阿毘曇、毘尼,即教理與律制的通達;「形體具足」則指名聞大德、能感財利,乃至臥具、湯藥、眾具皆得豐足。三事合觀,兼攝智慧(捷疾)、說法(色)、福德資具(形體),是此經論述修行者「具足」時最核心的術語組合。值得注意的是,此處「具足」並非抽象的「圓滿」形容,而是逐項列出可驗證的條件——能答問、能說法、能感供養——帶有強烈的實務性格。

二、受具足:出家大戒之專稱

經中另一高頻用法為「於正法、律出家、受具足」,此處「具足」即 upasampadā(近圓、具足戒)之譯,指正式取得比丘資格。婆蹉種外道求出家,佛制四月於和尚所受衣而住,而後「度彼婆蹉出家於正法、律出家、受具足,成比丘分」。須跋陀羅於佛般涅槃前最後得度,經文徑書「彼尊者須跋陀羅即於爾時出家,即是受具足,成比丘分」,省略四月觀察期,顯示特例。偈頌中亦見「出家受具足」之簡稱。此用法中「具足」已名詞化,與「出家」構成動賓結構,語義固定為受大戒,與前述三具足之形容詞性用法截然不同。

三、偈頌中的「具足」:明行具足

經末偈頌以「具足牟尼心,及業身口滿,明行悉具足,以法而讚歎」讚佛。此處「具足」修飾「明行」(vijjā-caraṇa),謂三明與諸行皆已圓滿,屬佛德描述,與聲聞三具足及受戒義均不同層。偈中「業身口滿」與「具足」互文,可見此經以「具足」與「滿」為近義互訓。

四、術語形式小結

《雜阿含經》論「具足」時,形容詞用法一律以「X具足」偏正結構出之(捷疾具足、色具足、形體具足、明行具足),不另造複合詞;名詞用法則固定為「受具足」三字動賓式,不說「受具足戒」,亦不說「受大戒」「受近圓」——後二者為他經或律藏用語,此經不用。

大智度論T1509 · 釋經論部

《大智度論》於釋初地菩薩說法功德時,將「具足」與「清淨」對舉,作為菩薩所說正法之雙重標準。論文明言:「離三毒垢故,但說正法,不雜非法,是名清淨。八聖道分、六波羅蜜備故,名為具足。」 此處「清淨」就離過而言——離三毒、不雜非法;「具足」就立德而言——以八聖道分與六波羅蜜之完備為其內涵。論主以「備」字訓釋「具足」,謂修行法門悉皆齊備,方稱具足,非泛言豐足,而有確定所指:即八聖道分與六波羅蜜二者皆備。此為本論對具足最核心之界定,將此詞從一般性的「充足」義收攝為特定法門圓滿之術語。

其次,本論於菩薩十地修行脈絡中賦予「具足」以階段性義涵。論中設問:口業有四種(妄語、惡口、綺語、兩舌),何以初地但說實語?答曰:「是菩薩行初地,未能具足行此四業故,但說實語;第二地中則能具足。」 據此,具足並非初發心即得,而須隨地位升進而漸次成就。初地菩薩僅能就實語一門着力,至第二地始得四種口業之具足。是知本論所言之具足,容有「分具」與「滿具」之別,與菩薩階位相配。

復次,論中另設問難:初地中何以但說十事?答以:「佛為法王,諸法中得自在,知是十法,能成初地;譬如良醫,善知藥草種數,若五、若十,足能破病,是中不應難其多少。」 此喻雖非直接釋「具足」一詞,然「足能破病」之「足」與「具足」義理相通:法門之數不在多寡,在於足以對治煩惱、成就該地功德。佛所施設之初地十法,即為初地之具足標準,不可增減難問。由此觀之,本論之「具足」兼具二義:一者就所修法門言,謂八聖道分、六波羅蜜悉備;二者就所證地位言,謂該地所應修法圓滿無缺。二者相即:法門備則地位成,地位成則法門足。

總之,《大智度論》以「備」釋「具足」,以八聖道分、六波羅蜜為其所指,以菩薩十地為其展開脈絡,以初地「未能具足」、二地「則能具足」顯示其漸次性,以良醫足病之喻說明各地位自有其具足之量。
