What This Concept Is Saying (这个概念在说什么)

In contemporary usage, the term "householder" or "lay practitioner" (居士, *jūshì*; Sanskrit: *gṛhapati*) is often treated as a generic, polite title for anyone who identifies as a Buddhist without wearing monastic robes. However, in the foundational texts of early Buddhism, *gṛhapati* carries a much richer, dual-layered meaning: it is simultaneously an exact economic classification in ancient Indian society and a revolutionary statement on spiritual equality in the Buddha’s Path to Liberation (解脱道, *jiětuō dào*).

1. The Secular Dimension: Class, Occupation, and External Markers

In early texts such as the *Dīrgha Āgama* (《長阿含經》) and *Madhyama Āgama* (《中阿含經》), society was categorized into the "Four Castes" (四姓, *sìxìng*): Kshatriya (刹利, *chàlì*, rulers/warriors), Brahmin / Vanzhi (婆罗门/梵志, *póluómén/fànzhì*, priests/intellectuals), Householders (居士, *jūshì*, agriculturalists, merchants, and wealth accumulators), and Sudras / Artisans (首陀罗/工师, *shǒutuóluó/gōngshī*, manual laborers).

- Origin and Role: The householder class arose from beings who "delighted in managing domestic enterprises and accumulating abundant wealth" (好营居业,多积财宝) or "engaged in various occupations to maintain their livelihood" (习种种业以自营生). Their defining economic activity was "agricultural production and management" (田作, *tiánzuò*). - Social Hierarchy: In the conventional social order, householders were categorized alongside artisans as possessing "lower virtue" (下德, *xiàdé*) compared to the "highest virtue" (最上德, *zuìshàngdé*) attributed to rulers and priests. They were expected to show deference and make offerings to Brahmins. When a householder class produced exceptional worldly excellence, the texts even counted the "Householder Gem" (居士宝, *jūshì bǎo*) as one of the Seven Treasures of a Wheel-Turning Monarch (转轮圣王, *zhuànlún shèngwáng*). - **External Markers (相标帜, *xiāngbiāozhì*)**: The texts vividly depict the secular appearance of a householder: "wearing clean white garments, wrapped in a white turban, holding a staff and parasol, and wearing secular shoes" (著白净衣,白巾裹头,拄杖执盖,著世俗屣).

2. The Spiritual Dimension: Absolute Equality and the Path to Liberation

While ancient Indian society rigidly sorted people by bloodline and social standing, the Buddha introduced a radical paradigm shift: the law of Karma (业报, *yèbào*) and the potential for ultimate awakening are completely blind to social caste.

A householder approaches liberation through two distinct yet equally valid paths:

1. The Path of Full Renunciation: Upon hearing the Dharma, a householder recognizes that household life is bound by family and material entanglements—"I am now at home, bound by wife and children, unable to practice the pure holy life in absolute clarity" (我今在家,妻子系缚,不得清净纯修梵行). Recognizing worldly attachment as impure, they shave their hair, put on the three monastic robes (剃除须发,服三法衣), leave the "householder lineage" (居士种, *jūshì zhǒng*), and join the "renunciate lineage" (沙门种, *shāmén zhǒng*). Through strict moral discipline and spiritual cultivation, they can directly realize Arhatship (阿罗汉果, *āluóhàn guǒ*), declaring: "Birth is exhausted, the holy life is established, what needed to be done has been done, there is no further state of being" (生死已尽,梵行已立,所作已办,不复受有).

2. **The Path of Household Liberation ("Cutting Off Secular Affairs", 断俗事, *duàn súshì*)**: For those who remain in secular life, the Buddha radically redefined what it means to "renounce." In the *Madhyama Āgama*, when a householder named Pūraṇa (晡利多居士) claimed he had abandoned secular affairs simply by handing over all his wealth to his children and living off begged food, the Buddha corrected him. In the Noble Discipline (圣法律, *shèng fǎlǜ*), true abandonment of secular affairs is not an external divestment of assets, but the **"Eightfold Cutting Off of Secular Affairs" (八支断俗事, *bāzhī duàn súshì*)**: - Refraining from killing (离杀) - Refraining from stealing / taking what is not given (离不与取) - Refraining from sexual misconduct (离邪淫) - Refraining from false speech (离妄言) - Abandoning greedy attachment (无贪著) - Abandoning ill will and anger (无害恚) - Abandoning envy and resentment (无憎嫉恼) - Abandoning overweening pride (无增上慢)

3. The Core Metaphors and Equal Capacity for Transformation

To shatter the caste-based prejudice that lower-status householders were spiritually inferior, the Buddha presented the famous **Parable of Fire-Making (钻木取火之喻, *zuān mù qǔ huǒ zhī yù*)**: Whether one uses precious, aromatic woods like Sal or Sandalwood (symbolizing rulers and priests) or coarse, rotten wood like dry pig troughs or castor wood (弊木, *bìmù*, symbolizing householders and artisans), when friction is applied, the fire produced is identical in flame, color, heat, and light. The capacity of the fire to perform its function is unchanged by the origin of the wood.

Furthermore, the texts specify Five Qualities of Readiness (五种可调御特质) that allow anyone—regardless of background—to achieve complete liberation in spiritual practice: 1. Faith / Confidence (信, *xìn*): Trust in the reality of liberation and the Noble Path. 2. Physical Health / Little Illness (少病, *shǎobìng*): A body balanced enough to sustain practice. 3. Honesty and Candor (不谄不诓, *bùchǎn bùkuāng*): Freedom from deceitfulness toward oneself, teachers, and companions. 4. Diligent Energy (精勤, *jīngqín*): Steadfast effort in abandoning unwholesome states and cultivating wholesome ones. 5. Wisdom (智慧, *zhìhuì*): Clear discernment into impermanence and the nature of phenomena.


A Walkthrough in Modern Life (生活里的走查)

To truly grasp the concept of the householder, we must step past ancient Indian imagery and observe how these exact dynamics play out in contemporary existence.

``` [Secular Identity & External Markers] ──► [Economic Production & Accumulation] (Business Suit, Laptop, Smartwatch) (Salary, Mortgage, Investments) │ ▼ ┌─────────────────────────────────────────────────┴─────────────────────────────────────────────────┐ │ The Crossroads of Modern Practice │ └─────────────────────────────────────────────────┬─────────────────────────────────────────────────┘ │ ┌─────────────────────────────────────────┴─────────────────────────────────────────┐ ▼ ▼ [False Renunciation / Escape] [True "Eightfold Cutting Off"] • Quitting job abruptly; dumping burden on family. • Retaining role while purifying internal actions: • Claiming "spiritual detachment" while full of subtle pride.

Scenario: The Commute, the Corporate Ladder, and the Family Home

1. Recognizing the "External Markers" (相标帜) Imagine boarding a crowded morning subway train. You wear tailored work clothes, carry a laptop bag, wear a smartwatch, and hold a thermal coffee cup. In early texts, this corresponds precisely to "wearing clean white robes, holding a staff and parasol, wearing secular shoes." These are the external symbols of a householder engaged in "agricultural production and wealth accumulation"—today translated into corporate projects, quarterly targets, mortgages, and family care.

2. The Entanglement ("妻子系缚") At your desk, as slack notifications pop up alongside mortgage reminders and family group chats, you feel a deep tension. This is what the sutras describe as realizing that "household life is bound by ties, making it difficult to practice pure holiness." You feel consumed by the treadmill of generating income and maintaining lifestyle standards.

3. The Trap of "False Renunciation" Overwhelmed, you might dream of walking away: "I’ll resign tomorrow, move to a remote village, turn off my phone, and live off minimal savings." *Where modern people map it wrong*: People often confuse spiritual abandonment with physical evasion. Just like Householder Pūraṇa, who thought handing his money to his sons and begging food meant he had "abandoned secular affairs," quitting your job while leaving your family in financial distress or carrying underlying resentment is not spiritual liberation. It is merely shifting the burden onto others while your inner afflictions remain intact.

4. Walking the "Eight支 (Eightfold) Cutting Off" in the Office True householder practice occurs directly within the active matrix of daily life. When a colleague gets the promotion you worked for, or when an aggressive email lands in your inbox, the Eightfold Cutting Off comes alive: - No Ill Will (无害恚): You pause your gut reaction to send a stinging, passive-aggressive reply. - No Jealousy (无憎嫉恼): Instead of harboring toxic envy toward your promoted peer, you notice the sting in your ego and let it dissolve without acting on it. - No Deceit / Non-Lying (不谄不诓 / 离妄言): You refuse to manipulate project data to cover a mistake, choosing radical workplace honesty. - No Overweening Pride (无增上慢): When you succeed, you do not look down on subordinates or believe you are inherently superior.

5. Lighting the Fire (钻木取火) Whether you sit in a monastery or in an open-plan office, when you bring mindful presence to a stressful moment, the fire of clarity produced has the exact same heat and light. The mind that drops anger in a corporate meeting experiences the exact same unbinding as the mind that drops anger in a meditation hall.


Why Modern People Need It (当代人为什么需要它)

1. Reclaiming Spiritual Agency in an Algorithmic World

Modern commercial society continuously pressures individuals to define their identity entirely by external status symbols—their "white garments and secular shoes." At the same time, spiritual paths are often marketed as exotic consumer escapes (wellness retreats, mountain hideaways).

The classical concept of the *gṛhapati* restores spiritual agency right where you stand. It teaches that your capacity for awakening is not dictated by your job title, bank balance, or whether you wear robes. It places the entire weight of liberation on your internal transformation—your practice of moral restraint and insight.

2. Dismantling the Dualism of "Monastic vs. Secular"

The Buddha's Fire Metaphor acts as a ultimate equalizer. It reminds us that spiritual realization is a matter of *cause and effect*, not *caste or costume*. If the five qualities—faith, physical balance, honesty, diligent effort, and wisdom—are applied to the wood of daily life, illumination is guaranteed.

3. Alignment and Contrast with Contemporary Science

In cognitive science and modern psychology, researchers study how mindfulness practices reduce amygdala reactivity, lower cortisol levels, and interrupt default mode network (DMN) rumination during stress.

- The Parallel: Neuroscience confirms that practicing non-reactivity (refraining from ill will, pride, or jealousy) rewires neural pathways, breaking habitual stress responses in high-pressure work environments. - The Critical Difference & Limitation: Science views these practices primarily as tools for stress reduction, emotional regulation, or productivity enhancement within current societal structures. In contrast, the Buddhist path of the householder uses these moral and mental disciplines to dismantle fundamental delusion (*avidyā*), break the cycle of karmic bondage, and realize ultimate liberation (*Nirvāṇa*). Brainwave optimization is a mere side effect; total freedom from suffering is the goal.


Common Misunderstandings and Clarifications (常见误读与澄清)

1. Misunderstanding: "Householder" is just a casual honorific for any lay Buddhist.

*Clarification*: In classical scriptures, *gṛhapati* is a precise social-economic status (those engaged in production, management, and wealth accumulation) paired with a rigorous spiritual definition. It is not an idle title of politeness; it demands the concrete implementation of the Eightfold Cutting Off of Secular Affairs and the cultivation of the Five Qualities of Readiness.

2. Misunderstanding: Lay practice is inherently a second-class, inferior version of enlightenment.

*Clarification*: The Parable of the Fire-Making explicitly rejects this hierarchy. Wood from a dry dog trough (representing lower social castes) yields fire with the exact same flame, color, heat, and light as fire ignited from sandalwood. Provided a householder fulfills the conditions of moral purity and insight, their realization of truth is identical to that of any renunciate.

3. Misunderstanding: "Renouncing secular affairs" means abandoning world responsibilities.

*Clarification*: As demonstrated in the Buddha's dialogue with Householder Pūraṇa, dumping family or financial responsibilities while remaining filled with internal greed, pride, or resentment is a delusion. True "cutting off of secular affairs" in the Noble Law is an internal execution: severing harmful physical/verbal actions (killing, stealing, misconduct, lying) and mental afflictions (greed, ill will, jealousy, pride) while continuing to function responsibly in society.

4. Misunderstanding: Householder liberation means you can practice without rules or moral discipline.

*Clarification*: The texts show that a householder's liberation requires strict, unyielding moral discipline. Whether one chooses the path of full monastic renunciation (*Śramaṇa*) or remains at home practicing the Eightfold Cutting Off, the standard for clearing mental impurities remains uncompromising. Freedom in the householder life is attained not by lowering the standard of liberation, but by elevating daily conduct to the level of sacred practice.

Canonical EntryAI-generated

一、 定义与核心要义

在早期佛教经典中,“居士(gṛhapati)”是一个兼具世俗社会阶级属性与佛法修行平等属性的核心概念。在世俗层面,居士是指通过特定生产生活方式(如营生、积财、田作)而形成的社会阶层,与刹利、婆罗门等并列为印度社会的基本种姓。在佛法修行层面,居士被赋予了完全平等的解脱地位。他们不仅可以通过听闻正法、舍离世俗、出家修道来彻底证得阿罗汉果,亦可以在圣法律中,通过依循“八支断俗事”进行在家的清净修行,其断行与解脱成就与高阶种姓无二无别。

二、 主要阐述

1. 居士的起源、社会地位与世俗角色

根据经典的记述,居士阶层有着明确的语源与阶级起源。在早期人类社会的发展中,一部分众生“好营居业,多积财宝”,因而被大众称为“居士”;或者由于“习种种业以自营生”,从而在世间形成了“居士种”这一特定阶层。在世俗的社会阶级划分中,居士与刹利、婆罗门(或梵志)、首陀罗(或工师)并称为“四姓”或“四种名”。

在世俗的阶级互动与观念中,居士阶层处于特定的社会定位。作为“四姓”之一,居士在传统上需要“常尊重、恭敬、供养婆罗门”。在德行与社会地位的判定上,居士与工师种被世俗划分为“下德”,而刹利与梵志则被视为“最上德”。居士在世俗中的主要职业和自有财物被定义为“田作”(即农业耕作),若居士轻慢其田作之业,则会失去利益。在血统与族数的判定上,凡是出生于居士族者,即被归入居士之数。此外,在转轮圣王治世的叙事中,优秀的居士还被列为转轮圣王具足的“七宝”之一,称为“居士宝”。

2. 业报规律与因果平等

经典强调,居士在因果业报面前与刹利、婆罗门等其他种姓完全平等,并不因其世俗地位而有差异。居士若身、口、意行不善业,身坏命终后必受苦报;若身、口、意行善业,命终后必受乐报;若行善恶混合之二种行,则受苦乐并存之报。

3. 出家修道与解脱路径

经典详细描述了居士从世俗生活走向彻底解脱的完整修行历程: - 觉悟与发心:当居士或居士子听闻如来宣说之正法后,会产生信乐之心,并反思自身处境,认识到“我今在家,妻子系缚,不得清净纯修梵行”,或者体悟到“世间恩爱污秽不净,何足贪著”。 - 舍家修行:基于上述觉悟,他们选择“剃除须发,服三法衣(或法服),出家修道”,从而脱离原有的“居士种”,加入“沙门种”。 - 持戒与断恶:出家后的居士与出家人一同舍弃世俗饰好,具足诸戒行。他们慈心不杀、不盗、净修梵行(不淫)、不妄语、不两舌、不恶口、不绮语,并远离饮酒、香华、高床、非时食、蓄积财物及奴婢畜生等放逸与虚伪之事。 - 证果解脱:出家修道的居士,通过“修七觉意”与“修无上梵行”,能够迅速成就道果,于现法中自身作证:“生死已尽,梵行已立,所作已办,不复受有”。

4. 在家修行的“断俗事”与平等成就

对于选择保留世俗身份的居士,经典也给出了明确的修行指导。居士在世俗中有着特定的“相标帜”,如“著白净衣,白巾裹头,拄杖执盖,著世俗屣”。针对居士如何对待世俗生活,经典进行了深刻的辨析:真正的“断俗事”并非形式上将财物施舍给子嗣、自己仅靠乞食存命,而是应当依循圣法律中的“八支断俗事”来修行,即:依离杀、断杀,依离不与取、断不与取,依离邪淫、断邪淫,依离妄言、断妄言,依无贪著、断贪著,依无害恚、断害恚,依无憎嫉恼、断憎嫉恼,依无增上慢、断增上慢。

在佛法修行与解脱上,居士具有与刹利、梵志完全平等的地位。居士若能“正趣”,同样能够“得善解,自知如法”。佛陀以取火为喻,说明无论是用名贵的娑罗、栴檀木,还是用燥猪狗槽、伊兰檀木等弊木(喻指居士、工师等下等种姓),只要用钻钻之,皆能生火,且所生之火皆有焰、色、热、光,能作火事。这表明居士修行同样能产生功德,达成解脱。在“断行”(修行断惑)上,居士只要具备“信、少病、不谄不诓、精勤、智慧”这五种可调御的特质,其断行成就与刹利、梵志、工师并无任何差别。

三、 不同部类与译本的表述差异

在不同的经典部类中,关于“居士”及相关概念的用词和表述存在以下差异: 1. 并列种姓的称谓差异:在《長阿含經》中,与居士并列的种姓常表述为“刹利、婆罗门、首陀罗”;而在《中阿含經》中,则常表述为“刹利、梵志、工师”,其中以“梵志”对应“婆罗门”,“工师”对应“首陀罗”。 2. 居士后代的称呼:在《長阿含經》中,统称为“居士子”;而在《中阿含經》中,则出现了具体人物的称呼,如“善生居士子”。 3. 出家与在家装束的对比表述:在《長阿含經》中,侧重于描述居士出家时的装束,如“剃除须发,服三法衣”或“法服修道”;而在《中阿含經》中,则详细描绘了居士在家的“相标帜”,即“著白净衣,白巾裹头,拄杖执盖,著世俗屣”。 4. 阶级起源的表述细微差异:在《長阿含經》内部,对于居士起源的表述也有两种微细差别,一处强调其“好营居业,多积财宝”,另一处则强调其“习种种业以自营生”。

四、 与相关概念的关系

1. 与“四姓”的关系:居士是印度传统四姓之一。虽然在世俗德行与社会地位上,居士常被视为低于刹利和婆罗门(梵志)的“下德”阶层,但在因果业报规律以及佛法修行的正趣、善解与断行成就上,居士与高阶种姓完全平等,无有差别。 2. 与“沙门种”的关系:居士属于世俗的“居士种”。当居士听闻正法、觉悟世间恩爱污秽后,通过“剃除须发,出家修道”,便脱离了原有的居士种,正式加入“沙门种”。 3. 与“转轮圣王七宝”的关系:在转轮圣王治世的功德展现中,“居士宝”是与金轮宝、白象宝、紺马宝、神珠宝、玉女宝、典兵宝并列的七宝之一,代表了世俗社会中居士阶层的最高成就与效能。

五、 代表性原文引用

1. 关于居士起源与出家: 《長阿含經》:“彼众生中有人好营居业,多积财宝,人称为居士……剃除须发,法服修道,舍兵仗,入沙门种。”

2. 关于居士的世俗装束与在家修行: 《中阿含經》:“晡利多居士著白净衣,白巾裹头,拄杖执盖,著世俗屣……世尊告曰:‘居士!此是居士相标帜……圣法律中,有八支断俗事。’”

3. 关于修行平等的钻木取火之喻: 《中阿含經》:“若有钻木以取火者,或持娑罗、栴檀……或持燥猪狗槽、伊兰檀木……此等皆是弊木。用钻钻之,皆能生火,此火皆有焰、色、热、光,皆能作火事。如是,若生刹利、居士、工师族者……若能正趣,得善解,自知如法。”

長阿含經T0001 · 阿含部

《長阿含經》論及「居士」一詞,主要見於種姓緣起與四姓平等之敘事,用語以「居士」及「居士種」為主,未見「長者」「家主」等異稱。其論述可分數端。

其一,居士為四姓之一,因營生積財而得名。經中敘世間種姓之始,謂「彼眾生中有人好營居業,多積財寶,因是眾人名為居士」;又云「彼眾生中習種種業以自營生,因是故世間有居士種」。是知本經以經營家業、多積財寶為居士得名之由,屬世間分工之一類,與剎利、婆羅門、首陀羅並列為四姓。

其二,居士種亦得厭世出家、修道證果。經言剎利、婆羅門、居士、首陀羅四種之中,皆「或時有人自厭己法,剃除鬚髮,而披法服」,於是始有沙門之名;居士種中有人思惟「世間恩愛汙穢不淨,何足貪著」,遂「捨家,剃除鬚髮,法服求道」,自稱「我是沙門」。此中居士種人出家修七覺意,能於現法中自身作證「生死已盡,梵行已立,所作已辦,不復受有」。是本經不以種姓限修道,居士種與餘三姓同得出家證果。

其三,業報平等,不以種姓而有差別。經中反覆申說:剎利、婆羅門、居士、首陀羅,若身口意行不善,身壞命終必受苦報;若身口意行善,必受樂報;若行二種,則受苦樂報。居士種之業果與餘姓無異,善惡之報繫於身口意三業,不繫於種姓出身。

其四,居士亦入轉輪聖王七寶之數。經敘菩薩若在家當為轉輪聖王,七寶具足,其六曰「居士寶」。此處「居士寶」為聖王治世之佐助,與金輪、白象、紺馬、神珠、玉女、典兵諸寶並列,是居士一詞又見於理想王政之敘事。

其五,居士為世所敬事之姓。摩納白佛言「世有四姓——剎利、婆羅門、居士、首陀羅,其彼三姓,常尊重、恭敬、供養婆羅門」。此雖出婆羅門之口,亦見居士於四姓秩序中居敬事婆羅門之位。

總之,本經之「居士」,一為因營居業、積財寶而得名之種姓,二為可出家證道之修行種姓,三為業報平等之眾生一類,四為轉輪王七寶之一。用語固定作「居士」「居士種」,與後世以「長者」「家主」譯 gṛhapati 之經論用詞有別,此為本經術語之特色。

中阿含經T0026 · 阿含部

《中阿含經》中「居士」一詞有兩種用法:一為具體在家信眾之稱號,二為四種姓制度中之第三階級。

作為具體信眾稱號,經中以「給孤獨居士」、「善生居士子」稱呼特定在家弟子,彼等聞佛說法後「歡喜奉行」,為經文結尾之固定格式。此處「居士」指在家奉佛之長者,「居士子」則指居士之子。

作為種姓分類,經中將社會分為「剎利、梵志、居士、工師」四種姓。本經用「梵志」而非「婆羅門」,用「剎利」而非「剎帝利」,用「工師」而非「首陀羅」,用「居士」而非「吠舍」——皆以意譯或簡稱出之,此為本經譯語之特徵。

在與欝瘦歌邏梵志的對話中,梵志主張四種姓各有奉事對象與自有財物:居士之自有財物為「田作」,若居士輕慢田作,則便失利,「猶如放牛人不能看牛者,則便失利」。佛以「強與他肉」之喻破斥梵志自作主張而不自知其說之根據。

本經最核心的居士論述,在於破除種姓決定論。佛反覆以譬喻說明:一切百種人皆能持澡豆洗浴去垢,皆能以若干種木鑽火長養,火之㷿、色、熱、光不因木種而異。由此得出結論:「梵志若正趣者,彼得善解,自知如法;剎利、居士、工師若正趣者,亦得善解,自知如法」。佛又以混血之子為喻——剎利女與梵志男所生,「我不說彼剎利,亦不說梵志,我但說彼他身」——說明種姓身分非本質固定。居士雖居四姓第三,然依正趣修行,與梵志同得善解,無有差別。

然而,在與拘薩羅王波斯匿的對話中,佛亦承認世俗層面之差別:「剎利、梵志種,此於人間為最上德,居士、工師種,此於人間為下德也」。但論及「斷行」時,佛指出決定因素非種姓,而是個人之信、少病、不諂不誑、精勤、智慧五種品質;不信者不能斷,懈怠者不能斷,與種姓無涉。

綜觀本經,「居士」兼具社會階級與修行身分雙重意涵:世俗中居四姓第三、以田作為業、屬「下德」;修行上則不因種姓而受限,正趣者皆得善解,斷行成就唯視個人品質而定。

雜阿含經T0099 · 阿含部

《雜阿含經》論「居士」,並非就居士一類單獨立說,而是將之置於四種姓的平等框架中予以定位。經中摩訶迦旃延尊者對摩偷羅王說:「婆羅門、剎利、居士、長者,此四種人悉皆召來,以財以力使其侍衛,先起後臥,及諸使令,悉如意不?」王答「如意」。尊者隨即追問:若剎利為王、居士為王、長者為王,是否同樣能使四姓侍奉?王亦答「如意」。由此得出結論:「四種姓者,皆悉平等,無有勝如差別之異。」

在此論述中,「居士」的術語形式即與「婆羅門」「剎利」「長者」並列的四姓之一,指在家從事營生、擁有財力者。經文並未賦予居士任何宗教修持上的特殊定義,而是將之作為社會身分的一種,用以破斥婆羅門「我第一,他人卑劣,我白,餘人黑,婆羅門清淨,非非婆羅門」的種姓優越論。摩訶迦旃延的核心判語為:「業真實者,是依業者」——決定人高下的不是出生種姓,而是所造之業;四姓差別不過是「世間言說耳」,「乃至依業,真實無差別也」。

值得注意的是,本經以「居士」與「長者」分列為二,二者並非同義互訓:居士側重在家營生之身分,長者則偏向年高德劭之稱謂,但在四姓平等的論證中,兩者同屬被婆羅門貶抑的對象,同享「依業不依姓」的平等地位。此處「居士」一詞不含後世「在家菩薩」或「優婆塞」的信仰內涵,純粹是社會階層分類中的一環。

此外,經中另有一處以「長者」為對話對象的殘段,僅存「答言:『長者!』」一句,以及勸勉長者「汝當前進,慎勿退還」並繼之以偈的片段。此二處雖未直接論及「居士」之名,但顯示本經對在家身分者(長者、居士一類)採勸進態度,以偈頌鼓勵其精進不退,與四姓平等之說互為表裏:既破出身之執,又策勵在家人向前修行。
