What this concept is saying

Shàngshì (上士, “the superior person” or “person of the highest quality”) does not denote social rank, masculinity, or a fixed spiritual title. Here 士 means a person considered according to the quality and orientation of their life. “Superior” is likewise relational: one is called 上士 only within a particular threefold comparison with 下士 (xiàshì, lower person) and 中士 (zhōngshì, middle person).

The two treatises in the supplied material employ that comparison differently. Their definitions should be kept distinct rather than blended into a single formula.

In the *Abhidharmakośabhāṣya* (《阿毘達磨俱舍論》, T1558), the classification concerns what a person continually seeks:

- The lower person “constantly seeks their own happiness” (恒求自身樂), even when diligently applying effort. - The middle person seeks the extinction of suffering, recognizing that conditioned pleasure can itself become a basis for suffering: it changes, ends, and feeds further craving. - The superior person continually seeks “suffering for oneself and happiness for others” (自苦他安樂), together with “the permanent extinction of others’ suffering” (他苦永滅), because they “take others as themselves” (以他為己).

The wording 自苦 must not be softened out of existence, but neither should it be turned into praise of self-harm. In this contrast, the superior person no longer makes personal comfort the governing criterion. They are prepared to accept hardship, cost, and vulnerability when that genuinely brings others welfare, and they seek something deeper for others than temporary relief: the ending of suffering itself. Ascetic injury, martyrdom for its own sake, or compulsive self-neglect would add meanings the cited passage does not state.

The decisive phrase is 以他為己—“taking others as oneself.” This is more radical than being kind while one’s own interests remain central. Ordinarily, another person’s pain reaches us as information, while our own pain arrives as an emergency. The superior person works against that asymmetry. Another being’s suffering is allowed to make a claim as serious as the claim made by one’s own.

The *Yogācārabhūmi-śāstra* (《瑜伽師地論》, T1579) uses 上士 across a much wider range of classifications. Its most central scheme concerns 自利 (zìlì, benefiting oneself) and 利他 (lìtā, benefiting others):

- Neither self-benefit nor other-benefit: lower person. - Only one of the two: middle person. - Both self-benefit and other-benefit: superior person.

This definition prevents altruism from being confused with self-erasure. A person who helps everyone while steadily destroying their own capacity possesses only one side of the pair. So does someone who cultivates personal peace but leaves their conduct toward others untouched. In this classification, superiority consists in the completeness of both.

The treatise also says that bodhisattvas “take others’ affairs as their own affairs” (以他事為自事). This closely resembles the *Abhidharmakośabhāṣya*’s 以他為己, but the two passages should not be treated as interchangeable definitions. One classifies people by what they continually seek; the other presents multiple classifications according to the matter under discussion.

Those classifications include the following:

- In relation to evil, the superior person neither commits evil nor delights in it. Outward restraint alone is incomplete if the mind still admires cruelty, deception, or exploitation. - In relation to what one esteems, the person who esteems the true Dharma (正法, saddharma) is superior. “Esteeming” Dharma means allowing truth and the path of transformation—not convenience, prestige, or tribal loyalty—to carry decisive weight. - A superior ruler possesses completeness of fortunate circumstances, effective capacity, and virtue. A superior minister combines loyalty or trustworthiness, practical skill, and wisdom. These are contextual definitions, not claims that political status itself is spiritually superior. - Superior speech has both well-formed, harmonious expression (辭句善順) and appropriate content (是所宜). Pleasant wording without fitting truth or purpose is insufficient; appropriate content delivered carelessly is also incomplete. - In acquiring and using wealth, the superior person acts lawfully and without recklessness, supports self, spouse, dependants, relatives, and friends properly, and also cultivates fields of merit through giving. - In eating, the superior person reflects before eating, does not become greedily attached, clearly sees food’s liabilities, knows the way of release from attachment, and has understood and relinquished the relevant bondage. This is not merely “healthy eating.” Its subject is the relationship between nourishment, craving, and freedom. - Giving may be called superior according to different criteria. In terms of the gift, its smell, taste, and tangible quality are excellent. In terms of the recipient or “field,” giving is directed toward those of outstanding virtue, or includes both the poor and worthy fields of merit. In terms of mind, one rejoices before giving, is inwardly clear while giving, and does not regret it afterward. These are separate classifications; a generous mood does not automatically make a defective or harmful gift excellent in every respect. - In ethical discipline, the superior person refrains fully and consistently, encourages others to refrain, praises ethical conduct, and rejoices on meeting others who practice it. Receiving discipline within a well-taught Dharma and Vinaya without deficiency is also called superior. Ethics here is not private innocence alone: it includes the moral atmosphere one helps create. - In meditation the treatise distinguishes defiled 靜慮 (jìnglǜ, meditative absorption), mundane purified absorption, and 無漏靜慮 (wúlòu jìnglǜ, undefiled absorption). One abiding in undefiled absorption is called superior. Calmness by itself is therefore not the highest criterion: concentration can coexist with defilement, or remain a refined but still conditioned state.

A helpful way to understand this diversity is that 上士 is sometimes a global description of orientation and sometimes the top member of a local three-level scale. A superior gift, superior way of eating, superior minister, and person abiding in undefiled absorption are not thereby declared to occupy one identical spiritual attainment. The common pattern is completeness, accordance with Dharma, freedom from corrupt motivation, and—where the particular classification concerns relationships—the inclusion of others’ welfare.

This usage is also earlier and broader than the later Tibetan presentation commonly called the “three scopes” or “three kinds of persons.” The later system is historically related to three-person terminology, but its lower, middle, and higher scopes come with their own path structure. It should not be imported wholesale into these two passages. A traditional dictionary preserves the central *Yogācārabhūmi* formula that one possessing both self-benefit and other-benefit is called 上士, while scholarship notes that three-person language was in circulation before Atiśa’s later path arrangement. [Ding Fubao’s *Dictionary of Buddhist Studies* entry](https://zh.wikisource.org/zh-hant/%E4%BD%9B%E5%AD%B8%E5%A4%A7%E8%BE%AD%E5%85%B8/%E4%B8%8A%E5%A3%AB), [Chung-Hwa Institute article on the historical distinction](https://www.chibs.edu.tw/ch_html/chbj/04/chbj0411.htm)

A walk-through in ordinary life

Imagine someone—call her Mei—commuting to a demanding job while helping care for an ill parent.

On the train, Mei opens her phone. An algorithm quickly offers outrage, shopping, and flattering content. At this first moment, the threefold distinction in the *Abhidharmakośabhāṣya* asks not simply, “Is using a phone good or bad?” It asks: *What is she continually seeking?*

If the governing impulse is “Give me stimulation, reassurance, and pleasure,” that maps onto the lower person’s pursuit of personal happiness. It remains so even if Mei is industrious and highly competent: the verse explicitly allows the lower person to be diligent. Efficiency does not by itself transform the aim.

If she begins to see that the cycle of craving, brief satisfaction, loss, and renewed craving is itself oppressive, and seeks release from that cycle, her orientation resembles the middle person’s search for the cessation of suffering. This does not mean that every wish to reduce screen time is liberation practice. The mapping concerns recognition of conditioned pleasure as an unreliable basis and the resulting wish to end bondage, not merely a productivity hack.

Then a message arrives: her parent has had a difficult night. Mei gives up a comfortable evening to arrange care. This may instantiate 自苦他安樂—accepting hardship so another may be at ease—but only if it truly serves the other. Feeling guilty, performing sacrifice to control the parent, or silently accumulating resentment is not automatically “superior” because it hurts. Pain is not the virtue; the decentering of self-comfort in wise service is.

She also asks a deeper question: “How can I help with fear, isolation, and the causes of continuing distress, not merely solve tonight’s logistics?” That begins to resemble the concern for 他苦永滅, the ending of another’s suffering. An ordinary caregiver cannot literally guarantee permanent liberation for someone else. The phrase instead exposes the horizon of the superior person’s concern: not merely making suffering temporarily less visible, but addressing its causes and supporting the path out.

Now walk through the same day using the distinct categories of the *Yogācārabhūmi*.

Mei arranges care for her parent, but she also sleeps, eats, seeks help, and sets workable limits. That can express the conjunction of self-benefit and other-benefit. If she abandons the parent for personal convenience, other-benefit is missing. If she sacrifices sleep until she becomes ill and unable to care for anyone, self-benefit is missing. “Both are present” does not mean that every decision produces equal comfort for everyone; it means the course of practice does not exclude either side.

At work, colleagues begin ridiculing an absent employee. Mei does not join in. More subtly, she notices the pleasure of belonging to the group through someone else’s humiliation and declines to feed that pleasure. This follows the definition precisely: not doing evil and not delighting in evil. Merely keeping silent while inwardly savoring the attack fulfills only the visible half.

A manager asks her to hide a serious problem in a report. To “esteem the true Dharma” here is not to attach a Buddhist slogan to the document. It is to let truth, non-harm, and sound principle outweigh convenience and reputation. Yet the textual category says “esteeming Dharma”; it should not be reduced to the modern idea of being generally authentic.

Mei explains the problem to the manager in language that is calm and easy to hear, but she does not conceal the facts. Her speech attempts to satisfy both conditions: 辭句善順, words and sentences well composed, and 是所宜, content suited to the situation. If she flatters the manager with falsehood, the phrasing may be pleasant but the content is not appropriate. If she speaks truth mainly to humiliate him, correct information alone does not make the speech excellent in the full sense described.

When she is paid, she earns without fraud or reckless speculation, supports herself and those properly dependent on her, helps family and friends within her means, and gives beyond her immediate circle. This is the treatise’s category of lawful acquisition and responsible use of wealth. It is not a condemnation of money, nor permission to call any profitable activity “right livelihood.” The manner of acquisition, absence of recklessness, and purposes of use all matter.

At lunch, she pauses before eating. She recognizes food as necessary support, notices the pull toward using it as anesthesia for stress, and remembers that every meal also involves cost, dependence, and eventual hunger again. This maps to reflective eating, non-attachment, seeing food’s drawbacks, and knowing release. Counting calories, choosing fashionable ingredients, or feeling ashamed of appetite is not the same thing. The classical concern is craving and liberation, not body-image discipline.

She brings good food to her parent rather than passing along what she herself would reject. That addresses excellence in the *object given*. She also gives to a struggling neighbour and supports a community of serious practitioners, addressing the classifications based on recipients. Before giving she is glad, while giving her mind is clear rather than contemptuous, and afterward she does not brood over the expense; this addresses the classification based on the giver’s mind. These dimensions should not be collapsed. Good intention, good material, and a fitting recipient are related but separately assessed.

Suppose Mei has undertaken a precept against false speech. She refrains herself, encourages her team not to falsify the report, openly values truthful conduct, and feels genuine happiness when a colleague also refuses deception. This follows the full ethical sequence: personal restraint, encouraging restraint, praising it, and rejoicing in fellow practitioners. The common mistake is to map “keeping precepts” only onto private non-violation.

In the evening she meditates. Her mind becomes very still. The *Yogācārabhūmi* does not permit us to conclude from stillness alone that this is the superior, undefiled absorption. Concentration may be mixed with craving for unusual experiences, may be a wholesome but mundane purified state, or may be undefiled. From the outside—and often from one sitting alone—those cannot responsibly be equated. The text’s distinction is a warning against mistaking altered state for liberation.

None of this requires pretending that Mei has become a certified 上士. The categories are better used as instruments of examination than as identity badges. The moment “I am a superior person” becomes emotionally important, the classification is already being recruited into self-concern.

Why contemporary people need it

Contemporary life is extraordinarily good at optimizing means while leaving ends unexamined. A person can work harder, track more habits, answer faster, and build better systems without ever asking what all that capability continually serves. The *Abhidharmakośabhāṣya* cuts beneath productivity to motivation: diligence is spiritually indeterminate until we know whether it serves private pleasure, release from suffering, or a concern that treats others as oneself.

This matters in algorithmic life. Recommendation systems can infer what keeps a person engaged, but engagement does not answer whether the underlying desire is worth strengthening. Artificial intelligence can help allocate resources or compose compassionate words, but it cannot make the user’s intention non-self-centred merely by producing benevolent-looking output. The comparison is limited: algorithms are engineered systems, while the Buddhist analysis concerns suffering, intention, ethical cultivation, and liberation. Neither computing nor neuroscience has “proved” the Buddhist classification.

The concept also corrects two opposing distortions of care.

One distortion is insulated self-development: meditation, therapy, fitness, and financial security become an increasingly sophisticated enclosure around “my experience.” The *Yogācārabhūmi*’s two-benefit definition asks whether personal cultivation becomes beneficial conduct toward others.

The opposite distortion is sanctified burnout. People in caregiving, activism, parenting, and service professions may believe that exhaustion proves love. But the definition requiring both self-benefit and other-benefit refuses to identify goodness with disappearance of the self. Meanwhile, the *Abhidharmakośabhāṣya*’s willingness to bear hardship prevents “self-care” from becoming an absolute veto against inconvenience. Read together—but not merged—the two texts yield a demanding balance: do not organize life around personal comfort, and do not destroy the conditions that make sustained benefit possible.

Upper-person practice also joins intention to structure. Compassion is tested in speech, money, food, generosity, ethical influence, and meditation. The liberation path is therefore not confined to an inward feeling. Daily activities reveal whether greed is weakening, whether harm is being abandoned, whether Dharma is truly esteemed, and whether the boundary between “my problem” and “your problem” is loosening.

Within the path to liberation, 上士 names a decisive reorientation: freedom is no longer imagined as a private possession. The *Abhidharmakośabhāṣya* presents the widening of concern toward others’ welfare and cessation of suffering. The *Yogācārabhūmi* shows that such elevation must penetrate ordinary conduct and, at its contemplative summit in the cited classification, reach undefiled absorption.

Yet the supplied passages do not say that every person called 上士 has attained one uniform stage, bodhisattva ground, or final fruit. “Superior” may describe the highest member of a particular ethical, social, economic, or meditative classification. Its place on the path is thus diagnostic and formative: it shows what maturation looks like in a given domain, without supplying a single certificate of attainment.

Common misunderstandings and clarifications

“上士 means a saint or an officially advanced practitioner.”

Not necessarily. In these materials it is a comparative designation applied under different criteria. A superior minister is classified by loyalty, skill, and wisdom; superior giving may be classified by gift, recipient, or mind; superior meditation is specifically undefiled absorption. These are not one undifferentiated rank.

“It simply means an altruist.”

That is too narrow. Other-regarding concern is central in the *Abhidharmakośabhāṣya*, and both-benefit is central in one *Yogācārabhūmi* classification. But the latter also defines superiority contextually through freedom from evil, esteem for Dharma, complete capacities, appropriate speech, lawful livelihood, reflective eating, excellent giving, comprehensive ethical conduct, and undefiled absorption.

“自苦 means Buddhists should seek pain.”

The text’s wording must be retained, but pain is not presented as an independent good. Its force in the three-person contrast is that the superior person accepts suffering or hardship for others’ happiness and cessation of suffering because they take others as themselves. Deliberate injury, abusive relationships, and avoidable burnout do not become liberating merely because they are painful.

“Taking others as oneself means having no boundaries.”

No. The *Yogācārabhūmi* expressly calls the conjunction of self-benefit and other-benefit superior. Wise boundaries can protect both. The phrase overturns moral indifference; it does not require obeying every demand, enabling harmful conduct, or pretending that one person can control another’s liberation.

“Self-benefit and benefiting others always conflict.”

Sometimes immediate interests conflict, but the classification points to a whole practice in which both are cultivated. Ethical discipline, wisdom, stable livelihood, and freedom from compulsive craving can benefit the practitioner precisely by making reliable benefit to others possible. Conversely, caring for others can loosen self-absorption and thus become part of one’s own cultivation.

“Pleasant speech is superior speech.”

Only half the definition has been met. The phrasing must be harmonious and the content must be appropriate. Manipulative reassurance, elegant deception, and polished cruelty fail the second condition.

“Good intentions make a gift superior.”

The treatise evaluates giving under separate headings: the quality of the thing given, the field or recipient, and the giver’s mind before, during, and after giving. Excellence in one dimension should not be used to erase negligence in another.

“Meditative calm proves an undefiled state.”

It does not. The very classification distinguishes defiled absorption, mundane purified absorption, and undefiled absorption. Intensity, silence, bliss, or unusual experience alone cannot establish which is present.

“Upper, middle, and lower are labels for judging other people.”

Used that way, the teaching easily becomes fuel for conceit. Its sharper use is self-examination: What am I continually seeking? Which side of self-benefit and other-benefit have I excluded? Do I merely avoid visible wrongdoing, or have I stopped admiring it? What do my speech, money, meals, giving, ethics, and meditation disclose about the direction of my mind?

The deepest meaning of 上士 is therefore not “someone better than other people.” It is a life whose centre of gravity has shifted. Personal pleasure is no longer the final court of appeal; another’s suffering is no longer merely external; Dharma is honoured in concrete choices; and wholesome qualities are cultivated completely enough to benefit both oneself and others. The title matters far less than that movement.

Canonical EntryAI-generated

1. 定义与核心要义

「上士」是与「下士」「中士」相对建立的最上一类士夫。《阿毘達磨俱舍論》着重其对待自他的立场:恒常勤求「自苦他安樂」与「他苦永滅」,因为能「以他為己」。《瑜伽師地論》则依不同事类分别判定上士,其基本行相是自利、利他二行俱有,并可表现为离恶、重法、德能具足及善心善行圆满。因此,「上士」在两论中都由下、中、上的对举显示其殊胜,但具体判准并不完全相同,须依各论原有分类分别理解。

2. 主要阐述

《阿毘達磨俱舍論》以一颂集中辨别三士:下士虽勤作方便,恒求的仍是自身快乐;中士求苦寂灭,因为乐亦为苦所依;上士则不以自身安乐为唯一目标,而恒勤求自身受苦、他者安乐以及他者之苦永远灭除。其根本理由是「以他為己」,即在所求之事上以他者如同自身。本论的重点不是罗列上士的修行德目,而是以所求目标和自他取向划分三类士夫。

《瑜伽師地論》的分类较为广泛。就利益行为而言,无自利行亦无利他行者为下士,仅具其中一种者为中士,二行俱有者为上士;诸菩萨「以他事為自事」,也被列入上士。就善恶意乐而言,不作恶且不乐恶者为上士;就所尊重者而言,重正法者为上士。

在世俗身份与处事能力方面,国王须同时具足果报圆满、士用圆满和功德圆满,臣下须兼有忠信、伎能和智慧,方称上士。言语若「辭句善順」,所说内容又「是所宜」,即属上士所说的「愛似愛語」。对于财欲,上士依法而不孟浪地积聚财宝,既正当地安养自身、妻子、眷属与知友,也在沙门、婆罗门处修殖福田。

在饮食方面,上士思择而食,不生贪染,深见饮食过患、善知出离,并对食已断已知。布施则可依施物、施田和施心分别判别:施物的香、味、触美妙具足;向具功德的最胜福田行施,或兼施贫苦者与具德胜田;施前欢喜、施时心净、施后无悔,皆是相关分类中上士的表现。

在持戒方面,上士不但于一切分、一切时自行远离所应远离者,还劝他远离、赞美持戒,见同法者便心生欢喜;住于善说法毘奈耶中受戒而无缺漏者,也称上士。在禅定分类中,本论使用「靜慮」一词,区分染污静虑、世间清净静虑和无漏静虑,住无漏静虑者名为上士。

3. 不同部类与译本的表述差异

毘曇部《阿毘達磨俱舍論》以「下士」「中士」「上士」三名作简明对举,核心用语是「自苦他安樂」「他苦永滅」和「以他為己」。另有「下中上隨心」之语,以「下中上」概括三级差别,但文字不足以扩充上士的定义。

瑜伽部《瑜伽師地論》除使用「三士」「上士」外,还依语境称其为「補特伽羅」「人」,并以「國王」「臣」等具体主体呈现上、中、下的差别。其特色不是以一项所求统摄上士,而是在自利利他、善恶意乐、正法、资生、布施、持戒及静虑等类别中,各依条件是否圆满建立最上位。

现有材料只涉及上述两论,未提供同一论的异译文本,故不能据此列举同经异译的词语分歧。《俱舍论》另见「三位」「三善根」之说,但原文未明言该「三位」即三士,也未将三善根专属于上士,不应并入核心定义。

4. 与相关概念的关系

上士首先与下士、中士构成三级关系。《俱舍论》中,三者的差别主要在恒常追求的对象:下士求自身之乐,中士求灭苦,上士则求他者安乐与他苦永灭,并以他为己。《瑜伽师地论》中,三级差别常表现为无所具、部分具足和圆满具足;例如自利、利他俱无为下士,仅具其一为中士,二者俱有为上士。

上士也与菩萨、正法、布施、持戒和静虑发生关系,但这些关系须限于原文所设类别:菩萨以他事为自事,重正法者为上士;布施时施物、施田或施心殊胜,持戒时自作并劝他、赞叹及随喜,住无漏静虑,皆可在各自分类中称为上士。这些称谓并不表示材料已将所有上士统一判定为某一修行阶位或果位。

5. 代表性原文引用

《阿毘達磨俱舍論》:「下士勤方便,恒求自身樂」;「中士求滅苦,非樂苦依故」;上士则「恒勤求,自苦他安樂,及他苦永滅,以他為己故」。

《瑜伽師地論》的代表性表述包括:自利行、利他行俱有者名「上士」;诸菩萨「以他事為自事」;言语「辭句善順」而「是所宜」者,为上士所宣说;静虑分类中,住「無漏靜慮」者名上士。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》以三士階次之對比來界定「上士」,其論述集中於一首頌文,將修行者依發心深廣分為下士、中士、上士三等,而上士之殊勝正在於其心量超越自利,以他苦為己苦。

一、三士並列中的定位

本論以「下士勤方便,恒求自身樂」界定下士——其一切精進方便皆圍繞自身之樂;「中士求滅苦,非樂苦依故」界定中士——已見樂為苦之所依,故所求不在得樂而在滅苦。在此對照之下,「上士恒勤求,自苦他安樂,及他苦永滅,以他為己故」,上士之所求兼攝自他:既求自身之苦止息,更求他人之安樂,且求他人之苦永滅。其所以能如此,論文明言「以他為己故」,即視他人如己,他苦即己苦、他樂即己樂,此為上士區別於下、中二士之根本所在。

二、上士之「恒勤求」

論文於上士特用「恒勤求」三字,與下士之「勤方便」相對。下士亦勤,然其勤僅為方便手段,目標止於自身一時之樂;上士之勤則為「恒」,無有間斷,且所求非一己之樂,而是自苦滅、他樂成、他苦永滅三重目標同時並進。此「恒」字顯示上士之發心非暫時興起,乃持續不斷之志業。

三、「以他為己」為上士之體性

論文以「以他為己故」一句收束上士之定義,此為因果說明:正因上士能將他人視為自己,故能自然生起求他安樂、滅他苦之恆勤。此非外加之道德要求,而是心量轉化後之必然表現。上士之「上」不在事相上做了多少利他之事,而在其心已破自他之隔閡。

四、三士之分「隨心」而判

論中另以「下中上隨心」一句點明:下士、中士、上士之判別標準在於心,非在於外在行為或所修法門之高下。同一行為,若心求自樂即屬下士,心求滅苦即屬中士,心以他為己即屬上士。此「隨心」之判使三士成為動機論而非階位論,上士之「上」是心志之上,非果位之上。

五、術語形式

本論逕用「上士」一詞,與「下士」「中士」構成固定三目,未另立異名。論中不稱「菩薩」或「大乘人」,而以此三士框架攝一切修行者之發心差別,上士即其中發心最廣者。此為《俱舍論》作為阿毘達磨論書之表述特色:以精確之心理動機分析取代宗派名相。

瑜伽師地論T1579 · 瑜伽部

《瑜伽師地論》以「三士」(下、中、上)之框架貫穿修行各層面,對「上士」之論述極為豐富且系統化。本論不用「根器」一詞,而以「士」立名,核心判準為「行」之差別:「無自利行無利他行,名為下士;有自利行無利他行,有利他行無自利行,名為中士;有自利行有利他行,名為上士。」 此即上士之根本定義——自利利他二行具足。復以四種補特伽羅之行惡、樂惡與否重判三士:「非行惡亦非樂惡,是名上士。」 又依所重不同立三士:「重受欲」為下,「重事務」為中,「重正法」為上;更以「以他事為自事」之菩薩當上士之位。

本論獨特之處在於將三士判準逐一展開至世間與出世間各領域。世間層面:國王以果報圓滿、士用圓滿、功德圓滿「三圓滿無不具足」為上士;臣以忠信、伎能、智慧三者具足為上士;語以「愛似愛語」(辭句善順且是所宜)為上士;受欲以「一向以法及不孟浪積集財寶」且能修殖福田為上士;食以思擇而食、深見過患、善知出離且「已斷已知」為上士。

布施層面,本論從施物、施田、施心三維度分別建立三士:施物以「具足美妙香味與觸」為上;施田以「於具功德最勝福田而行惠施」為上,又細判「施於貧苦、具德勝田名為上士」;施心以「先心歡喜,施時心淨,施已無悔」為上。

持戒層面,本論從戒福業事、禁戒處所、戒心、別解脫律儀等多角度建立三士:戒福業事以「一切俱現」(離一切分、一切時離、勸他離、讚美、見同法者心歡喜)為上士;禁戒處所以住善說法毘奈耶而「不缺漏」為上;戒心以「為涅槃故受持禁戒」為上士;別解脫律儀以能受苾芻律儀為上;苾芻律儀以「具成四支」為上;律儀種類以成就「別解脫、靜慮、無漏三種律儀」為上;所受戒以成就「菩提薩埵所受戒律儀」為上士。

禪修層面:思惟方便以「已得成就任運思惟」為上;己得修以「俱得」奢摩他與毘鉢舍那為上;三摩地以「無尋無伺三摩地」為上;住修以「住無漏靜慮」為上士。

綜觀本論,「上士」並非單一固定之品格,而是一貫之判準模式:於任何修行面向,凡最圓滿、最清淨、最究竟者即名上士。術語上,本論用「補特伽羅」稱人,用「士」而非「根器」分等,用「毘奈耶」稱律藏,用「苾芻」稱比丘,用「奢摩他」「毘鉢舍那」稱止觀,皆為玄奘譯本之固定譯語。
