What this concept is saying

受用 (*saṃbhoga*, actual reception, enjoyment, or use) is what happens when something available to a sentient being becomes something actually lived through or put to use.

A meal may be on the table, money may be in an account, pleasant surroundings may have been produced by past karma, or a practitioner may have acquired a wholesome quality. In each case, there is a difference between “being obtained” and “being actually received and used.” 受用 names the latter side of the distinction.

This is why “enjoyment” is both a useful and a potentially misleading translation. In English, enjoyment normally suggests pleasure. Buddhist 受用 is broader: one may undergo a painful result, live through a neutral situation, use a material resource, or exercise an acquired spiritual quality. What matters is not whether the experience is pleasant, but whether the relevant object, result, or attained dharma has entered into actual experience or operation.

The *Abhidharmakośabhāṣya*, preserved in Chinese as the 《阿毘達磨俱舍論》 (*Abhidharma Treasury Treatise*, T1558), uses the term at several related but distinct levels.

First, it places 受用 beside “the support of cyclic movement,” “arising,” and “continuance”—「流轉所依」「生」「住」「受用」—when explaining the functions according to which the first fourteen elements are established. Here 受用 is not a newly invented mental factor, nor the name of one particular karmic fruit. It describes a function within sentient existence: beings do not merely arise and persist; they encounter and make use of worlds, bodies, faculties, objects, and results.

This matters for understanding saṃsāra. Cyclic existence is not only the production of another life. It is also the repeated conversion of conditions into lived experience: a body is acquired and inhabited; a world is encountered; pleasant and painful results become present; resources are consumed; identities and capacities are exercised. 受用 names this experiential phase of the process.

Its immediate psychological basis is 受 (*vedanā*, feeling or affective reception). The treatise summarizes the function of feeling with the compact statement:

「受領納隨觸。」

That is: feeling has the function of receiving or undergoing, and it arises following contact.

Here “feeling” does not primarily mean emotion in the modern sense. It is the affective reception of an encounter as pleasant, painful, or neither-painful-nor-pleasant. When eye, visible form, and visual consciousness support visual contact, for example, feeling receives the affective tone of that contact. The same basic pattern applies to the other senses and to mental contact.

受 and 受用 are therefore closely related, but they are not interchangeable:

- 受 (*vedanā*, feeling) is the mental factor whose function is affective reception—「領納」. - 受用 (*saṃbhoga*, actual reception or use) emphasizes that an obtained object, result, resource, or dharma is actually being undergone, enjoyed, or employed.

The distinction is something like the difference between “tasting” and “having the meal as one’s meal.” Tasting points to the immediate affective event; having the meal points to an available thing becoming something actually received and used. The analogy is imperfect, but it shows why 受用 should not simply be substituted for 受 wherever the latter appears.

The treatise further clarifies the network surrounding 受 through five forms of 順受 (“being related or conducive to feeling”). These are not five pieces of a single linear process. They are five ways of naming something according to its particular relation to feeling:

1. 自性順受 (*intrinsically related to feeling*) means all feelings themselves. It is named from feeling’s own nature. 2. 相應順受 (*associated with feeling*) means all contacts. Contact is the condition with which feeling is connected and following which feeling arises. 3. 所緣順受 (*object-related to feeling*) means all objects capable of serving as the objects of feeling. 4. 異熟順受 (*karmically resultant relation to feeling*) means karma capable of producing feeling as a maturation-result. 5. 現前順受 (*presently manifest feeling*) means the feeling that is actually occurring now.

This fivefold analysis prevents several common confusions. Contact is not feeling; it is associated with feeling. The object is not feeling; it is what feeling takes as its object. Karma is not the feeling-result itself; it may be the cause that matures into such a result. And a feeling that is presently manifest is not another feeling “experiencing” a first feeling.

Thus, when the treatise discusses “experiencing a pleasant feeling,” it is not positing a hidden observer-feeling that stands behind the pleasant feeling and consumes it. The pleasant feeling itself is present. This is philosophically important: Buddhist analysis does not need to insert a permanent owner between experience and the experienced tone of experience.

The three corresponding karmic expressions are 順樂受 (*karma conducive to pleasant feeling*), 順苦受 (*karma conducive to painful feeling*), and 順不苦不樂受 (*karma conducive to neither-painful-nor-pleasant feeling*). “Conducive” here concerns the relation between karma and the type of feeling that may arise as its maturation-result. It does not mean that karma mechanically manufactures every momentary feeling without supporting conditions.

A further qualification concerns 受資糧 (*resources or supporting conditions for feeling*). In one specific discussion of karma, the treatise explains that karma may produce not only a feeling-result but also the resources that enable that result to be experienced. For that limited interpretive purpose, “feeling” may encompass “feeling and its resources”—「受及資糧」.

Consider the difference between a disposition toward pleasant experience and the concrete conditions through which it becomes available: functioning faculties, food, shelter, medicine, social circumstances, or other necessary supports. The point is not that every occurrence of the word 受 secretly includes all these things. It is that, in this particular karmic context, a result cannot always be adequately described by isolating the moment of feeling from the conditions that make its manifestation possible. Extending this specialized usage to every discussion of 受 would distort the treatise.

The most revealing use of 受用 may be the distinction between 得 (*acquisition or attainment*) and actual use. The treatise can speak of 「已得受用」, what has been obtained and already used or experienced, and 「未得受用」, what has been obtained but not yet used or experienced.

This gives 受用 a place on the path of liberation. A dharma can in some sense be acquired without yet becoming an active capacity in the practitioner’s life. One may possess knowledge without applying it, have established a wholesome quality without bringing it to bear in a relevant situation, or have access to a contemplative capacity without presently entering and exercising it. The technical classifications in the treatise should not be reduced to these everyday examples, but the distinction they illuminate is exact: possession is not identical with functioning.

For practice, that difference is decisive. Liberation is not secured merely by accumulating Buddhist ideas, receiving instructions, collecting initiations, or remembering doctrinal lists. A teaching becomes transformative when it is repeatedly received, examined, cultivated, and made operative in the conditions where clinging ordinarily takes command. In this broader practical sense, the distance between 得 and 受用 is the distance between “I have learned this” and “this now changes how experience is met.”

At the same time, 受用 is not automatically liberating. Ordinary sentient beings also “use” karmically obtained bodies, environments, pleasures, pains, and faculties—and commonly do so under craving, aversion, and delusion. The question on the path is therefore not simply whether we receive and use what arises, but how. Is an agreeable result appropriated as “mine,” defended, and made into fuel for further thirst? Is a painful result turned into resentment and self-construction? Or is experience known as conditioned, unstable, and not fit to be taken as a permanent self?

The concept stands at an important junction: karma supplies results and supporting conditions; contact occasions feeling; feeling gives experience an affective tone; craving may seize that tone; and 受用 describes the result or object becoming part of a being’s actual life. Wisdom intervenes not by abolishing all practical use, but by removing appropriation and confusion from it.

A walkthrough in everyday life

Imagine an evening commute after a demanding workday.

You board a crowded train. Your phone is in your hand, your salary has arrived in your account, and a message from someone close to you remains unanswered. This one scene contains several meanings that are easily collapsed into the single modern word “experience.” The Abhidharma distinctions allow us to walk through it more carefully.

First, there are 境 (*objects*): the brightness of the screen, the sound of the train, pressure against the body, thoughts about the message, and the remembered image of the day’s conflict. In the terminology of the five relations to feeling, these may be considered from the side of 所緣順受: they are objects in relation to which feeling can occur.

The objects themselves are not yet 受. A glowing screen is not a pleasant feeling; another person’s sentence is not a painful feeling. This is one of the most frequent mapping errors. We routinely say, “That message hurt me,” as if pain were stored inside the words and transferred intact into the mind. Buddhist analysis distinguishes the object from the affective reception that arises dependently.

Second, there is 觸 (*sparśa*, contact). Visual contact occurs in dependence on the relevant faculty, object, and consciousness; mental contact occurs as the message is interpreted, remembered, and reconsidered. From the fivefold perspective, contact is 相應順受, that which is associated with feeling.

Contact is not a metaphor for physical collision alone. Nor is it identical with the complete emotional story that follows. It is the conjunction at which an object becomes experientially present through the appropriate faculty and consciousness.

Third, feeling arises following contact. Perhaps the notification produces a pleasant lift, the crowded carriage produces discomfort, and the repetitive motion of scrolling is largely neutral. These are instances of 受蕴 (*vedanā-skandha*, the aggregate of feeling): pleasant, painful, and neither-painful-nor-pleasant affective reception.

The pleasant lift is not yet love. The painful contraction is not yet the judgment “they do not respect me.” The neutral feeling is not the absence of experience. Those later emotions, interpretations, impulses, and narratives involve additional mental factors. 受 is the affective tone being received at the contact point.

Fourth, one of these feelings becomes 現前順受: the presently manifest feeling. Suppose the discomfort associated with the unread message now dominates awareness. There is no need to imagine a second internal subject who “has” the first feeling. The painful feeling itself is manifest, while other mental processes may recognize it, interpret it, resist it, or build a personal story around it.

Fifth, consider karma and result. The precise karmic history behind a particular experience is ordinarily not available to introspection, so one should not confidently announce, “This unpleasant train ride is punishment for a particular past deed.” That is speculative moral storytelling, not careful Abhidharma analysis.

What can be stated doctrinally is the general relation: karma capable of maturing into pleasant, painful, or neutral feeling is called 異熟順受 in relation to the corresponding result. Present conditions and current responses also matter. Buddhist karma is not permission to blame a suffering person, nor a claim that every inconvenience can be traced by us to one identifiable former act.

Sixth, notice 受資糧. The salary in your account is not itself a pleasant feeling. It may function as a resource that supports future experiences: food, rent, rest, healthcare, leisure, or generosity. A quiet home, available time, bodily faculties, and technological access may likewise support particular forms of experience. In the treatise’s specialized karmic discussion, such supports help explain why a result involves more than an isolated pulse of pleasure or pain.

But we must not now label every possession “feeling.” The bank balance remains a resource or condition; the pleasant or anxious tone arising in relation to it is feeling. The special phrase “feeling and its resources” does not erase that distinction.

Seventh, 受用 becomes visible. You use the phone, spend the salary, occupy the train, listen to music, read the message, and undergo the comfort or distress made possible by these circumstances. Available objects and acquired resources have entered actual life. This is 受用 in its broad sense of actual reception and use.

It is not confined to pleasure. Doom-scrolling is a form of use; compulsively rereading a painful message is also an actual undergoing of an available object. “Enjoyment” would be a poor English rendering in these cases if it implied delight.

Now suppose you remember a meditation instruction: before replying, recognize the painful feeling simply as painful feeling. You have already learned this instruction. In that sense, the teaching is something you possess. But if the instruction remains a remembered sentence while resentment writes the reply, it has not become operative at the decisive moment.

You pause. You feel the contraction without converting it immediately into “I have been rejected.” You notice the urge to retaliate, refrain from sending the first response, and answer later with greater clarity. The acquired teaching is now being used. This illustrates—not as a substitute for the treatise’s technical account, but as a practical analogy—the distinction between 已得 and 已得受用: having a dharma and actually bringing it into operation are not the same.

Even here, practice is not the suppression of feeling. Wisdom does not require you to turn pain into neutrality or pretend that a hurtful interaction is harmless. It requires seeing accurately: object is object, contact is contact, painful reception is painful reception, interpretation is interpretation, and the impulse to retaliate is a conditioned impulse. Once these are no longer fused into a single unquestionable “me being attacked,” ethical freedom has room to appear.

Why contemporary people need it

Contemporary life is organized around acquisition. We acquire devices, subscriptions, qualifications, information, therapeutic vocabularies, meditation techniques, and endless saved content. Digital systems are exceptionally good at placing things within reach. They are much less capable of ensuring that what we possess becomes wisely used.

A person may own hundreds of unread books, save dozens of meditation talks, and recognize the vocabulary of impermanence while remaining unable to stay with ten seconds of disappointment without grasping or lashing out. The concept of 受用 quietly asks: what has actually entered your life as a functioning capacity?

This question cuts in two directions.

On one side, it exposes the fantasy that possession guarantees benefit. Access to a teaching is not understanding; understanding is not cultivation; cultivation in a protected setting is not necessarily availability amid fear, fatigue, intimacy, parenting, or conflict. The distinction between 得 and 受用 encourages honest practice without contempt for gradual development. Something genuinely obtained may still need conditions before it can be fully exercised.

On the other side, it exposes how thoroughly we already “use” the fruits and conditions of life without recognizing them as conditioned. Clean water, mobility, education, bodily faculties, social trust, technology, and periods of safety easily disappear into the background. Because they are being used every day, they feel self-evident; because they feel self-evident, they are appropriated as entitlements. Reflection on 受用 can support gratitude and responsibility: this experience depends upon conditions, many of which were neither made nor controlled by “me” alone.

It also gives a precise way to examine consumer culture. Craving persuades us that acquisition and enjoyment are virtually the same event: once the product, status, relationship, or experience is obtained, satisfaction will supposedly be secured. But actual reception always unfolds through contact and feeling, and every feeling is conditioned and unstable. The desired object may be obtained while its use is anxious, distracted, brief, or disappointing. The problem is not necessarily the object. It is the promise of durable completion projected onto an inherently conditioned episode of use.

Algorithmic platforms intensify this confusion. They arrange an environment of nearly frictionless availability: another image, clip, opinion, purchase, or social comparison is always ready to be received. Yet the fact that content is continuously supplied does not mean it is meaningfully used. Much of it produces short affective pulses that condition another swipe.

One may compare this with the Buddhist sequence of object, contact, feeling, and reactive appropriation. But the comparison is only a heuristic. Computational models describe selected patterns in observable behaviour; Buddhist analysis belongs to a soteriological project concerned with suffering, karma, insight, and liberation. Neuroscience and behavioural science also continue to debate how conscious feeling, valuation, attention, and agency should be understood. They neither simply prove nor disprove the Buddhist account.

The practical value of the comparison is modest but real: contemporary systems compete at the point where contact becomes affectively charged. Practice restores a moment of discernment there. “Pleasant” need not become “more.” “Painful” need not become “destroy it.” “Neutral” need not automatically become “escape from boredom.”

In the path to liberation, this discernment matters because feeling is a major hinge between encounter and craving. 受用 shows the broader existential field in which that hinge operates: beings inherit conditions, encounter objects, undergo results, and use what has become available. Without wisdom, actual use renews ownership, thirst, and becoming. With ethical restraint, collectedness, and insight, the same field becomes a place for understanding conditionality.

A liberated relation to 受用 would therefore not mean refusing to eat, use medicine, inhabit shelter, enjoy beauty, or exercise cultivated qualities. The issue is not use versus non-use. It is use with or without appropriation. One can receive a pleasant condition without demanding permanence from it; meet pain without constructing an eternal victim around it; use resources without imagining an independent owner; and employ an attained wholesome quality without turning it into spiritual status.

This is where the concept opens beyond economics or psychology. It reveals an entire structure of bondage: “I obtained this; therefore it is mine; because it is mine, it must serve me; because it serves me, it should remain.” Insight interrupts that structure. What is received depends on causes. The receiving itself depends on contact. Its affective tone arises and ceases. Even the capacity to use a teaching is conditioned. Nothing in this analysis requires a permanent possessor standing outside the process.

The aim is not to make life unreal. It is to make our participation in life less possessive and therefore less painful.

Common misunderstandings and clarifications

“受用 just means pleasure or luxury.”

No. The term can include enjoyment, but its range is wider: actual reception, undergoing, or use. Painful and neutral results can also be lived through. A spiritual quality can be exercised. Translating it as “enjoyment” without qualification narrows the concept toward hedonism.

“受 and 受用 are two names for the same mental factor.”

No. 受 is the mental factor of affective reception and is included in 受蕴, the aggregate of feeling; it is also classified under 法处 (*dharma sense-field*) and 法界 (*dharma element*) in the relevant analytical schemes. 受用 is not an additional mental factor beside it. It emphasizes actual reception or use of an obtained object, result, or dharma.

“受 means emotion.”

Not precisely. Emotions such as jealousy, grief, affection, or anger are complex configurations. 受 identifies the pleasant, painful, or neutral affective tone of experience. Calling it “emotion” can obscure its more elementary and pervasive role.

“Contact, feeling, and the object are the same experience viewed poetically.”

They are related but analytically distinct. The five forms of 順受 preserve the differences:

- feeling itself: 自性順受; - associated contact: 相應順受; - the object of feeling: 所緣順受; - karma capable of producing the maturation-result: 異熟順受; - feeling presently occurring: 現前順受.

Flattening them into a vague notion of “experience” defeats the purpose of the analysis.

“A pleasant feeling is enjoyed by another inner feeling—or by a permanent inner observer.”

That is specifically the wrong model. “Experiencing pleasant feeling” need not imply a second feeling consuming the first. It refers to the pleasant feeling itself being manifest. Other processes may know, remember, name, or react to it, but this does not establish an unchanging owner behind the event.

“Every occurrence of 受 includes material resources.”

No. “Feeling and its resources” is a contextual expansion used in a particular discussion of karma and 順受. It explains that karma can produce both feeling-results and supporting conditions. It should not be converted into a universal definition of 受.

“If I possess a teaching or attain a quality, I am already making full use of it.”

Not necessarily. The distinction between 已得受用 and 未得受用 shows that acquisition and actual use can come apart. This should not be turned into an excuse to dismiss genuine attainment, nor into a simplistic claim that a dharma “does not exist” unless consciously noticed. It says only that being obtained and being exercised are distinguishable aspects.

“Karmic results explain exactly why every individual pleasure or pain occurs.”

The doctrine establishes relationships between karma and maturation-results; it does not authorize casual certainty about the hidden karmic history of another person’s illness, poverty, trauma, or good fortune. Present conditions are complex, and ordinary observers generally lack the knowledge required to identify specific past causes. Using karma to blame sufferers is both epistemically careless and ethically corrosive.

“The goal is to stop using or enjoying anything.”

That mistakes non-attachment for paralysis. Buddhist practice does not require denying functional distinctions: food nourishes, medicine treats illness, shelter protects, and cultivated qualities can be exercised. The problem is clinging—the demand that conditioned use provide an unconditioned self and permanent security.

“If everything is conditioned, practical responsibility disappears.”

The opposite follows. Because reception and use depend on conditions, how we shape conditions matters. Attention, ethical restraint, generosity, habits, companionship, and training all influence what becomes available and how it is received. Conditionality removes the fantasy of an isolated controller; it does not remove consequences.

The deepest lesson of 受用 is therefore not “enjoy what you have,” though gratitude may follow from it. It is this: observe the passage from availability to lived actuality. See what is merely possessed, what is genuinely operative, what conditions make reception possible, what feeling arises, and how craving attempts to convert temporary use into ownership.

At that point, an apparently ordinary word becomes a map of the path. Saṃsāra is continually “used” under ignorance: results are received, feelings appropriated, and conditions turned into further becoming. The path uses the same field differently. What is obtained is cultivated; what is felt is known; what is available is employed ethically; and what is conditioned is no longer mistaken for a lasting possessor or possession.

Canonical EntryAI-generated

1. 定义与核心要义

「受用」(saṃbhoga)在《阿毘達磨俱舍論》中,指有情对于境界、果报或已经获得之法的实际领受、享用与运用。其心理作用的基础是「受」:受以领纳为义,随触而生,能领纳所接触的境界;「受用」则进一步突出所得之境或所得之法已为有情实际领受。二者意义相关而层次有别,不能在所有语境中径直互换。

2. 主要阐述

第一,在诸法作用与诸界建立的论述中,本论将「流转所依」「生」「住」「受用」并列,由这些作用建立前十四界;在还灭方面,亦作相应的建立。这里的「受用」并非专指某一种业果,也不是另立一种心所,而是从有情活动的作用着眼,表示有情在流转与生存过程中对境界或所得的领受、享用。它与流转所依、生、住共同成为说明诸界差别的依据。

第二,就心理作用而言,本论以「受领纳随触」界定受:受的作用是领纳,并依随触而生。受与想、行等共同列入五蕴,称为「受蕴」;从处、界的分类说,受等心所又属于法处、法界。由此可见,本论说明心对境的领纳时,主要使用「受」与「领纳」;强调有情实际享有所得境界时,则使用「受用」。受是领纳作用本身,受用则偏重这一作用落实于所得境界或所得之法。

第三,在业果论中,「受」有时不只指受心所或受的异熟果,还可依特定语境兼摄支持该受现行的条件。本论指出,业并非唯独招感受,也能够招感作为其助缘的「受资粮」,所以在解释有关「顺受业」的语句时,可将「受及资粮」合称为「受」。这说明果报的领受不仅涉及苦、乐、不苦不乐等受的现起,也涉及使这种领受得以发生的资具与条件。不过,这只是该段对「受」字范围的专门说明,不宜据此认定一切「受」字都包含受资粮。

第四,本论列举「顺受」的五种形式,即自性顺受、相应顺受、所缘顺受、异熟顺受与现前顺受。自性顺受是一切受,相应顺受是一切触,所缘顺受是一切境,异熟顺受是能够招感异熟的业,现前顺受则是正在现行的受。这五种名称分别从受自身、与受相应之触、受所缘之境、能感受果之业,以及受的现前状态立名,显示「受」与触、境、业及异熟之间的不同联系。

其中,「受乐受」并不是说另有一个受去领受当前的乐受,而是就乐受自身现前而说。相关段落的重点在「异熟顺受」:业能够招感乐受、苦受或不苦不乐受的异熟果,因而分别称为顺乐受、顺苦受、顺不苦不乐受。此处所说的「顺」,着重表示业与其所招感之受果的关系。

第五,在退失的分类中,本论以所得功德「已得受用」或「未得受用」作为判别条件之一。这里的「受用」意义尤为明确:某法虽已获得,还须区别是否已经实际领受或运用。论中据此说明三种退,并分别涉及佛以及利根、中根、钝根者的差别;佛仅有其中最后一种退,其余根性则各有相应情形。该段显示,「得」与「受用」并不完全相同:已经获得之法,可能已经受用,也可能尚未受用。

3. 不同部类与译本的表述差异

本条所据材料仅见毘曇部《阿毘達磨俱舍論》(《阿毘達磨俱舍論》),没有提供其他部类经典或本论异译本的对应文字,故不能据此列出同一概念在不同经论或异译本中的实质分歧。就本论自身的用词而言,应辨明以下层次:论中采用「五蕴」「受蕴」,不作「五陰」;说明受的本义时用「受」「领纳」,说明实际享有所得时用「受用」;业果语境另有「顺受」「异熟顺受」「受资粮」等名称;退失语境则用「已得受用」「未得受用」。这些差异属于同一论中随论述对象而改变的术语形式,不应当作不同译本的异说。

4. 与相关概念的关系

「受」与「受用」关系最为直接。受以领纳为用,是五蕴中的受蕴,并摄于法处、法界;受用则指这种领纳落实为对所得境界或已得之法的实际享有。

「触」是受所随而生的条件,在五种顺受中又被称为相应顺受;「境」是受的所缘,故称所缘顺受。二者分别从相应条件与所缘对象说明受的发生。

「业」与「异熟受」构成果因关系。能招感相应受果的业称异熟顺受,并依其所感而说顺乐受、顺苦受或顺不苦不乐受。业还可能招感支持受现行的受资粮,因此特定语境中的「受」可以兼摄受及其资粮。

「得」与「受用」则是所得之法的两个不同方面:得表示法已经获得,受用表示所得已经实际被领受或运用,故本论能够进一步区分已得而已受用、已得而未受用等情况。

5. 代表性原文引用

本论界定受的核心语句为:「受领纳随触。」此语表明受以领纳为作用,并随触而生。

诸法作用的相关列举为:「流转所依」「生」「住」「受用」。其中「受用」与流转、生、住并列,参与诸界的建立。

业果论述中的代表性术语包括:「受资粮」「受及资粮」「自性顺受」「相应顺受」「所缘顺受」「异熟顺受」「现前顺受」,以及「顺乐受」「顺苦受」「顺不苦不乐受」。这些名称分别显示受与助缘、触、境、业、异熟和现前状态的联系。

退失分类所用的关键表述是:「已得受用」「未得受用」,明确区分已经获得之法是否已被实际领受、运用。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》對「受用」一詞之論述,散見於兩處偈頌,雖屬片段,然其義涵與作用脈絡皆可由此窺見。

一者,就二十四諦之建立而言,論頌云:「或流轉所依,及生住受用,建立前十四,還滅後亦然。」此中明示:前十四諦(苦、集等流轉所攝之真實法),不僅為流轉之所依,亦為「生、住、受用」三者之建立;而後十諦(滅、道等還滅所攝之真實法),其建立亦復如是。此處「受用」與「生」「住」並舉,三者同為流轉門中真實法所具有之功能面向——亦即,眾生於流轉生死之際,諸法既能生起,又能相續安住,且能對所感之境界果報領受並享用之。此一「生住受用」之架構,顯示受用乃流轉所攝真實法不可或缺之面向,而非僅為修道還滅後之獨有境界。

二者,就退墮之分類而言,論頌云:「應知退有三,已未得受用,佛唯有最後,利中後鈍三。」此處以「已得受用」與「未得受用」之別,作為區分三種退之準繩。所謂退之三種差別,即依眾生或已領受享用其所得功德、或尚未得受用其功德而立。頌文復明:佛陀之退,唯有「最後」一種(即未得受用之退),蓋因佛已究竟圓滿受用一切所應得之功德,故無已受用之後退失之理。至「利中後鈍三」一句,則就利根之補特伽羅而言,其退又分中、後、鈍三品之差別,仍以受用之已得與否為判攝之樞紐。

綜上可見,《阿毘達磨俱舍論》論「受用」一詞,其核心義涵為「領受並享用所得境界或果報」,與概念之通解一致。論中所採之術語形式,不另立異名,直接以「受用」二字表之,未見以其他異譯取代;其運用範疇則涵蓋流轉門真實法之功能建立,以及聖凡修道位次中退墮差別之判攝兩個層面。前者凸顯受用於生死流轉中即已成就之事實,後者則以受用為衡量功德得與未得、已失與未失之基準,二者皆緊扣「領納享用所得果報」之核心意趣。

瑜伽師地論T1579 · 瑜伽部

《瑜伽師地論》論「受用」一詞,主要有以下幾個層面的用法:

一、「受用」作為分析綱目之一。本論多次將「受用」列為分析事相的綱目,與數、處、量、壽、因緣果等並列;又在「處、及與事、求、受用、正行」之綱領中並列;於「眼等、與地等……受用、護」中亦列為條目;於「攝、制立、尸羅、無逸……受用、甚深、說、喻事」中為修學次第之一支。

二、「婬欲受用」:依界趣而有差別。本論詳述「婬欲受用」於諸趣的差別:地獄有情長時無間多受極猛利苦,男女互不起欲,更無二二交會之事;鬼、傍生、人中依身苦樂相雜,故有婬欲,男女展轉二二交會,不淨流出;欲界諸天雖行婬欲而無不淨,然於根門有風氣出,煩惱便息。又隨天階漸高,交會方式漸減:四大王眾天與三十三天「二二交會」熱惱方息,時分天「唯互相抱」,知足天「唯相執手」,樂化天「相顧而笑」,他化自在天「眼相顧視」。北拘盧洲「無我所故,無攝受故」,一切有情無攝受妻妾,亦無嫁娶;除樂化天及他化自在天外,大力鬼及欲界諸天皆如三洲人有嫁娶之事。

三、世間與出世「受用」之勝劣對比。本論以婆羅門與沙門的「受用」作對比:婆羅門受用「障道塗飾、香鬘、莊嚴具等」,又「現受用歌舞、作倡、戲笑等事」,更「現受用婬欲等法」,故是下劣;沙門「受用無罪正聞思修所成智慧」,故是勝妙。此處「受用」側重於能受用之法的性質,勝劣之判在於染淨。

四、「受用」於飲食知量。本論於「知量」科中,將受用之過程區為「受取」與「受用」兩階段:於受取中善知量者,謂於時、處、物、量皆如法而受;於受用中善知量者,則對所受之物,於時、處、所、量皆善知而用,勿令飢惱、勿不順斷、勿令諸界起不平等。

綜上,《瑜伽師地論》中「受用」一詞涵蓋三義:領納享用境界(婬欲等)、領納運用所受之物(飲食等)、以及作為觀察事相之綱目;其語義隨上下文而有側重,但皆不離「領受而享用」之核心。

《辯中邊論》論「受用」,並未將它限定為單一、孤立的心理活動,而是依不同論述脈絡,分別呈現為雜染運作中的一環、善法成果的一項,以及能受與所受境之間的作用關係。其用詞除完整的「受用」外,也見單稱「受」,又有「受用法成熟」與「受用成熟他」等複合表述,應依各段原文分別記錄,不宜強行合併為同一義項。

一、在說明世間雜染時,論中將「受用」列入一系列使世間受惱的作用或環節,與「覆障」「安立」「將導」「攝」「圓滿」「三分別」「引起」「連縛」「現前」「苦果」等並列,並總攝其由「虛妄分別」而有。此處「受用」的獨特側面,是它被置於雜染的連續結構中,並非泛指安樂享受;原文又以「三、二、七雜染」概括相關雜染差別,故小結宜保留其與虛妄分別及惱亂世間的關聯,而不另加超出本文的因果次第。

二、在另一組頌文中,「受用法成熟」與富貴、善趣、不捨有情、增德、趣入、解脫、施等諸善、無盡、無間及所作善決定等內容相連。此段以「障」統領若干項目,顯示「受用法成熟」是在所列障礙所對應的善法成果脈絡中提出。論中採用的確切術語是「受用法成熟」,不可僅改寫成一般所說的享受果報,因為原文特別將「受用」「法」「成熟」結合成一項表述。

三、與前段相應的簡略列舉中,論文又用「饒益、不害、受、增德、能入、脫、無盡、常起、定、受用成熟他」作概括。此處既單列「受」,又另說「受用成熟他」,說明本論在相關語境中區分簡稱的「受」與帶有成熟意涵的「受用」複合語;其中「他」明示此項表述涉及成熟他者,但原文未在所給文塊中進一步解釋其具體方式,故不宜外推。

四、論中另以「能受、所了境,用門義名處」說明「處」的名義。此處「能受」與「所了境」相對:一方著重能夠領受,另一方著重被了知的境;二者由「用門」之義而名為「處」。這一表述顯示,本論談領受時亦使用「能受」而非一概使用「受用」,並將領受能力、所緣境界與作用門徑並舉。就多譯名歸一而言,本論可記錄的原詞形式包括「受用」「受」「能受」「受用法成熟」及「受用成熟他」;各詞所屬脈絡不同,不應彼此任意替代。
