What Is the Concept Speaking Of?

In early Buddhist thought, "The Path of Purification" (Sanskrit: *visuddhi-marga*; Chinese: 清淨道) is not an abstract mystical state, nor is it a set of dogmatic rituals. It refers to the **sole, definitive, and systematic trajectory that leads to the complete, permanent eradication of greed (*rāga* / 貪), hatred (*dveṣa* / 瞋), and delusion (*moha* / 癡)**, ultimately culminating in "Unsurpassed Purity" (無上清淨 / 第一清淨)—the state of Nibbāna.

To understand the Path of Purification, one must first understand what Buddhism considers "impurity" (*kilesa* / 煩惱塵垢). Impurity is not physical dirt, nor is it an inherent sin encoded into human nature. It is the psychological pollution—the emotional reactivity, ignorance, and grasping—that clouds the mind and keeps sentient beings trapped in the cycle of birth, aging, illness, and death (*saṃsāra*).

The term consists of two distinct components that must be understood precisely:

1. **Purification (清淨, *Visuddhi*): The end result and the quality of the process. It is the complete unwinding and severance of defilements. It is not a temporary suppression of bad thoughts, but the absolute eradication of the root causes of suffering. 2. Path (道, *Marga*)**: The practical, cause-and-effect methodology required to achieve that state. A "path" implies direction, steps, and a verifiable framework.

1. The Core Engine: The Noble Eightfold Path (*Āryāṣṭāṅgamārga* / 八正道)

Early scriptures, such as the *Saṃyukta Āgama* (*雜阿含經*), directly equate the Path of Purification with the Noble Eightfold Path. The path is an integrated system: * **Right View (正見, *Sammā-diṭṭhi*)**: The entry point and anchor. It is the accurate, unvarnished perception of reality—seeing things as impermanent, unsatisfactory, and non-self (*anicca, dukkha, anattā*), and grasping the law of cause and effect (Karma). Right view directly dismantles delusion. * The Supporting Factor: Right Thought/Intention (正志), Right Speech (正語), Right Action (正業), Right Livelihood (正命), Right Effort (正方便), and Right Mindfulness (正念). * **Right Concentration (正定, *Sammā-samādhi*)**: The deep, unshakeable stabilization of the mind. When Right Concentration is cultivated, it severs the roots of greed and hatred, sealing the ultimate attainment of Unsurpassed Purity.

In some contexts, this entire engine is summarized as the "Path of Precepts, Concentration, Hearing, and Wisdom" (戒定聞慧道), emphasizing that deep wisdom must be nourished by listening to and reflecting upon the true Teaching (*Dharma*).

2. The Fourfold Structural Framework of Purification

The early sutras outline a progressive four-stage framework—often expressed as the "Four Purifications" or "Four Abandonments through Purification" (四種清淨 / 淨斷):

* **1. Purification of Conduct / Precepts (戒清淨 / 戒淨斷, *Sīla-visuddhi*)**: The essential baseline. It means abiding firmly in ethical restraint (*Prātimokṣa* / 波羅提木叉), possessing flawless moral dignity, and maintaining intense vigilance over even the slightest misstep. It is the conscious protection and mastery of physical, verbal, and mental actions. * **2. Purification of Mind (心清淨 / 心淨斷, *Citta-visuddhi*)**: Built entirely upon ethical purity. It requires abandoning unwholesome sensory desires and entering the meditative absorptions—from the First Jāna to the Fourth Jāna. This saturates the mind with calm stability, preventing it from being scattered by external turmoil. * **3. Purification of View (見清淨 / 見淨斷, *Diṭṭhi-visuddhi*): The birth of liberating insight. The early discourses outline five distinct gateways to achieve this: 1. Listening directly to the Buddha’s teaching; 2. Listening to wise spiritual companions; 3. Reciting and reviewing the teachings on one's own; 4. Explaining and teaching the Dharma to others; 5. Deeply contemplating and investigating the true nature of reality in solitude. Through these, the practitioner enters "Reality-Conformable Observation"** (如實正觀 / 如實觀察), transforming intellectual understanding into unshakeable personal conviction. * 4. Purification of Liberation (解脫清淨 / 解脫淨斷): The ultimate fruition where all subtle fetters are severed, fulfilling the complete "Body of Liberation" (*Vimutti-kāya*).

*(Note: In later Theravāda scholasticism, most famously Buddhaghosa’s 5th-century treatise *Visuddhimagga*, this framework was expanded into Seven Stages of Purification. However, the foundational early sutras anchor the entire structure in these core stages of Moral Discipline, Mental Stability, Realized View, and Liberation.)*

3. The Psychological Guardians: Sense of Shame (*Hri*) and Moral Dread (*Apatrāpya*)

The Path of Purification does not run on willpower alone; it relies on two crucial wholesome mental factors: * **Moral Shame (慚, *Hri*)**: An inner, self-respecting aversion to doing wrong. * **Moral Dread / Fear of Consequences (愧, *Apatrāpya*)**: An outward-facing awareness of the destructive, painful consequences that unwholesome actions bring upon oneself and others.

The suttas explicitly state that without *Hri* and *Apatrāpya*, human beings naturally deviate from the Path of Purification, plunging into reckless desires and endless suffering. With them, the path grows naturally, shutting the doors to birth and death.

4. The Contrast: Purification vs. "Seeking Purification Through Non-Paths"

The scriptures draw a radical distinction between the Path of Purification and "Seeking Purification Through Non-Paths" (非道求清淨). In ancient India, this meant blind asceticism (e.g., self-starvation, severe physical torture) or ritualistic sacrifices (such as worshipping the sacred fire). The Buddha pointed out that these methods are like a blind person trying to find a road. Because they lack Right View, no matter how much pain they inflict on themselves, they will never cleanse the mind of greed, hatred, and delusion.


A Walkthrough in Contemporary Life

To understand how the Path of Purification operates, we must pull it out of ancient monastic imagery and walk through it using the daily experiences of a modern individual—such as a corporate professional navigating an intense work dynamic.

Scenario: The Office Politics and the Promotion Crisis

Imagine you discover that a colleague has taken credit for a major project you led, securing a promotion you worked toward for two years. Your phone glows with a late-night email announcing their new title.

Here is how the mind defaults to "Impurity," and how the Path of Purification systematically steps in to transform the moment:

Step 1: Unwholesome Reactivity (The Default State of Impurity)

* **Greed (*Rāga*)**: "I needed that title and salary to feel secure and validated." * **Hatred (*Dveṣa*)**: A surge of rage, envy, and revenge. You draft a scorching email to human resources, subtle insults to ruin your colleague's reputation, or plan a passive-aggressive sabotage. * **Delusion (*Moha*)**: Believing that "If I destroy them, I will finally be happy," and forgetting that toxic actions carry heavy psychological consequences (*Karma*).

Step 2: Purification of Conduct (戒清淨 / 戒淨斷) in Action

* Where People Misunderstand: Many think "precepts" mean taking a monastic vow or passively suffering. In modern life, *Purification of Conduct* means active restraint under emotional distress. * The Walkthrough: Inspired by *Hri* (Moral Shame) and *Apatrāpya* (Fear of Evil Consequences), you catch your finger hovering over the "Send All" button on that scathing email. You realize: *"If I send this out of rage, I am polluting my own mind and creating chaotic office warfare."* You delete the draft. You refrain from lying, spreading rumors, or engaging in malicious gossip at the coffee machine. You lock down your physical and verbal behavior.

Step 3: Purification of Mind (心清淨 / 心淨斷) in Action

* Where People Misunderstand: Many believe "Purification of Mind" or concentration means suppressing thoughts or sitting in a blank trance. * The Walkthrough: The physical urge to lash out is contained, but your chest is still burning with resentment. You step away from your laptop, sit down, close your eyes, and anchor your focus on your breath (cultivating momentary concentration/samādhi). As you breathe, you stabilize the mind so it isn't swept away by the storm of indignation. You pull the mind out of reactive loops and bring it into a grounded, silent, and lucid present state.

Step 4: Purification of View (見清淨 / 見淨斷) in Action

* Where People Misunderstand: People mistake "View" for an opinion, an ideology, or toxic positivity ("Everything happens for a reason"). * The Walkthrough: With a calm mind (Purification of Mind), you engage in "Reality-Conformable Observation" (如實正觀): * You observe the surge of anger not as "MY anger," but as a temporary, conditioned sensation arising and passing away (*Impermanence / Anicca*). * You see clearly that clinging to the identity of "the victim" is the exact source of your suffering (*Unsatisfactoriness / Dukkha*). * You perceive that your career, your colleague, and your own identity are complex webs of causes and conditions, devoid of a static, unchangeable self (*Non-self / Anattā*). Total clarity dawns: The promotion was never "yours" to begin with; it was merely a temporary alignment of external conditions.

Step 5: Purification of Liberation (解脫清淨)

The anger vanishes—not because you forced it down, but because the underlying misunderstanding (Delusion) that fed it has been thoroughly dismantled by Wisdom. You step out of the room feeling completely unburdened, free from grudge, clear-headed, and equipped to deal with your career strategically and ethically. You have closed the door to a cycle of suffering.


Why Do Contemporary People Need It?

Modern society is suffering from an unprecedented crisis of "Non-Path Seeking" (非道求清淨).

When modern individuals feel anxious, burned out, unfulfilled, or overwhelmed by existential dread, they instinctively search for relief. However, most contemporary solutions are modern incarnations of the ancient "Non-Paths"—methods that soothe symptoms temporarily while leaving the underlying mental defilements intact:

1. Material and Algorithmic Hedonism: Turning to doom-scrolling, retail therapy, substance use, or endless content consumption to numb pain. This is seeking clarity through *Greed*, which only deepens mental addiction. 2. Aggressive Productivity and Extreme Wellness: Attempting to solve existential anxiety through relentless self-optimization, hyper-disciplined biohacking, or extreme physical regimens. Like the ancient ascetics who starved themselves thinking it would purify the soul, modern individuals torture their bodies and schedules, believing that perfect control over the external environment will grant internal peace. 3. The Trap of "McMindfulness": Treating mindfulness as a mere stress-reduction tool to make oneself a more efficient worker in a high-stress environment. Without the anchor of *Ethics* (Precepts) and *Insight* (Wisdom/Right View), mindfulness becomes an anesthetic rather than a path to liberation.

Why the Path of Purification is Essential Today: * It is a Structural, Causal Framework: The Path of Purification reminds modern people that mental peace is not an accident or a gift from an external entity; it is an algorithmic result of specific mental causes. If you want peace, you must systematically clean the inputs (Ethics), stabilize the processor (Concentration), and upgrade the software (Wisdom). * It Distinguishes Symptoms from Causes: Science and technology can optimize external comfort, but they cannot eradicate human greed, hostility, or delusion. The Path of Purification targets the ultimate source of human suffering—the unexamined mind.

Modern Analogy & Its Limitations: The AI / Operating System Analogy

* The Analogy: Think of the human mind as an Advanced AI Operating System. * Impurity (Defilements) = Bugs, malware, and inefficient loops in the code (Greed, Hatred, Delusion) that cause system crashes (emotional breakdowns). * Purification of Conduct = Setting up strict firewalls and input validation to stop bad data from entering the system. * Purification of Mind = Allocating processing power (RAM), defragmenting memory, and closing background clutter so the CPU runs cool and stable. * Purification of View = Re-writing the core source code by seeing how the system actually functions, deleting corrupt legacy scripts (delusional misperceptions of self). * The Limitation of the Analogy: An AI system is an unfeeling machine processing binary code. The Buddhist Path of Purification is not a cold, mechanical software patch; it is deeply interwoven with lived human experience, moral responsibility, deep compassion, and spiritual awakening. Furthermore, current neuroscience and computer science have no consensus on what consciousness actually is, nor can cognitive science replicate the transcendent, unconditioned liberation (*Nibbāna*) described in the Buddha's teachings. Science observes third-person data; the Path of Purification is an experiential, first-person transformation.


Common Misinterpretations & Clarifications

1. Misinterpretation: "Purification means physical asceticism or cutting off all human emotion."

* Clarification: Early Buddhism explicitly rejected severe self-mortification as a "Non-Path" (非道). The Path of Purification is not about killing feelings, nor is it about torturing the physical body. It is about cleansing the emotional reactivity (greed, hatred, delusion) that wraps around experiences. A fully purified person (*Arahant*) still experiences physical pain, cold, and hunger, and still displays warmth and compassion, but their mind remains totally unblemished by hostility or craving.

2. Misinterpretation: "Ethics (Precepts) are rigid moralistic rules imposed by an authority."

* Clarification: In the Path of Purification, ethics (*Sīla*) are not moralistic commandments from a deity, but practical, protective boundaries. They are grounded in *Hri* (self-respect/shame) and *Apatrāpya* (awareness of consequences). Just as a scientist wears protective gear not out of blind obedience, but because chemicals burn, a practitioner holds precepts because unwholesome actions burn the mind and destabilize concentration.

3. Misinterpretation: "View (見) just means adopting Buddhist dogmas."

* Clarification: In Western terms, "view" often means an opinion or an ideological stance. In early Buddhism, *Purification of View* (見清淨) is explicitly defined as "Reality-Conformable Observation" (如實正觀 / 如實觀察). It is not blind belief in text; it is the direct, unmediated seeing of physical and mental phenomena as they actually are—impermanent, interconnected, and void of an unchanging ego.

4. Misinterpretation: "You can skip Ethics and Concentration and go straight to Wisdom/Liberation."

* Clarification: The early scriptures present a strict, progressive dependency: Conduct leads to Concentration; Concentration leads to Wisdom; Wisdom leads to Liberation. Attempting to develop deep, liberating Wisdom without the grounding of Ethical Conduct is like trying to build a heavy skyscraper on shifting sand; without mental stability (Concentration), the mind is too chaotic to observe subtle mental processes accurately. The stages are interdependent and mutually reinforcing.

一、定义与核心要义

在《杂阿含经》的教义体系中,「清净道」(visuddhi-marga)被定义为通往「无上清净」与「第一清净」的唯一、正确且系统化的修行路径。所谓「清净」,是指彻底、永恒地断除贪、瞋、痴以及一切束缚众生的烦恼尘垢;而「道」则是达成此一状态的具体实践方法。经中明确指出,清净道即是八正道的具体实践,亦被概括为「戒定闻慧道」。这一修行路径与世俗的迷信祭祀、盲目苦行等「非道求清净」有着本质的区别,是圣弟子关闭生死之门、度脱生死流转的决定性道路。

二、主要阐述

《杂阿含经》从多个维度对「清净道」进行了深入且详尽的阐述,主要包括以下几个方面:

1. 八正道为清净道之本体 经中直接将八正道等同于清净道。具体而言,「正见」是清净道的起点与核心,修习正见能够直接断除贪、瞋、痴;而「正志、正语、正业、正命、正方便、正念、正定」这其余七支,同样被明确称为「清净道」的组成部分。特别是「正定」的修习,能够令修行者的贪、瞋、痴永断,从而证得「无上清净」。这表明清净道并非抽象的理论,而是以八正道为具体内容的实践法门。

2. 四种清净的修行架构 经中提出了一个系统化的修行架构,即「戒清净、心清净、见清净、解脱清净」(或称「戒净断、心净断、见净断、解脱净断」),这四者构成了清净道的渐次修学过程: - 戒清净(戒净断):这是修行的基石。圣弟子必须安住于戒律与波罗提木叉之中,做到威仪具足。在日常生活中,即使面对极其微细的罪业,也要生起深切的恐怖与警惕,精进地防护身口意三业,摄受身心,从而使「戒身」达到圆满满足。 - 心清净(心净断):在戒律清净的基础上,圣弟子需要远离欲恶不善法,具足安住于从初禅、二禅、三禅直至第四禅的禅定境界中。通过禅定的修持,令「定身」达到满足,并且在日常中常能执受此定心,不令散乱。 - 见清净(见净断):这是关于智慧与正见的确立。经中指出,圣弟子可以通过五种具体的途径来达成见清净:一是亲自听闻佛陀宣说正法;二是听闻其他明智的梵行者宣说正法;三是独自重诵、温习先前所听闻的佛法;四是为他人广泛地宣说、解释先前所听闻的法义;五是独处时深入思惟、观察先前所听闻的法义。通过这五种因缘,修行者得以「入如实正观」或「入如实观察」,从而对正法生起极大的欢喜与深切的信解。 - 解脱清净(解脱净断):在戒、心、见三种清净的基础上,最终导向烦恼的彻底解脱,实现「解脱身」的满足。

3. 惭愧二法的推动与守护作用 清净道的修持并非孤立进行,而是需要特定的心理机制来推动与守护。经中特别强调了「惭」与「愧」这两种善法对于清净道的关键意义。如果世间没有「惭」与「愧」这两种心理机制,众生就会放任烦恼,从而「违越清净道」,堕入生老病死的无尽轮回之中;相反,如果修行者能够成就「惭、愧」二法,就能够不断「增长清净道」,从而永远关闭生死之门,走向涅槃。

4. 对外道「非道求清净」的严厉批判 在阐述真正的清净道之同时,经中也对当时流行的各种外道修行进行了对比与批判。外道如「供养祠祀火」(祭祀事火)或盲目修持种种自饿、自残等苦行,皆被定性为「非道求清净」。经中形象地比喻,这些外道修行者如同盲人一般,「不知清净道」,在错误的道路上寻求寂静与解脱,其结果必然是「至竟无净时」,无法获得真正的清净。唯有依循佛陀的教导,出家受具足戒,精进修行,最终逮得「三明」(宿命明、天眼明、漏尽明),才是真正「沐浴离尘垢」而度脱生死的清净道。

三、不同部类与译本的表述差异

在《杂阿含经》的文本中,对于「清净道」及其相关修行阶段的表述,存在着多种同义异译或不同的称呼方式,这些差异反映了经文在传译和结集过程中的多样性:

1. 四种清净的称呼分歧:在阐述修行架构时,同一经文中并列出现了两套称呼。一套表述为「戒清净、心清净、见清净、解脱清净」;另一套则表述为「戒净断、心净断、见净断、解脱净断」。这两种表述在内涵上完全一致,皆指代戒、定、慧、解脱的渐次清净与断惑过程。 2. 修行路径的整体概括差异:在定义通往清净的道路时,经中一方面将其具体化为「八正道」(即正见、正志、正语、正业、正命、正方便、正念、正定);另一方面,又将其概括为「戒定闻慧道」。这两种表述虽然侧重点不同(前者强调八支圣道,后者强调戒、定、多闻、智慧的综合修持),但指向的都是同一个清净道。 3. 见清净达成状态的用词差异:在描述通过听闻、思惟、宣说佛法而达到见清净的状态时,经文中交替使用了「入如实正观」与「入如实观察」。这两种用词皆指对法义的如实了知与体证。 4. 外道邪道的称谓:对于不正确的修行道路,经中使用了「非道求清净」与「不知清净道」等表述,并具体指出了「供养祠祀火」等祭祀行为。

四、与相关概念的关系

1. 与「无上清净」及「第一清净」的关系 「清净道」与「无上清净」(或「第一清净」)是因果关系。清净道是修行的过程与方法,而无上清净则是修行圆满所证得的果位。修习正见等八正道,能断除贪、瞋、痴,最终证得「无上清净」;修习「戒定闻慧道」,则能获得「第一清净」。

2. 与「非道」的对立关系 「清净道」与外道的「非道」处于完全对立的状态。外道的事火、苦行等「非道求清净」行为,因为缺乏正见,如同盲人摸路,永远无法达到清净。只有佛法中的八正道与戒定慧,才是唯一的清净道。

3. 与「惭、愧」的依存关系 「惭」与「愧」是清净道得以维持和增长的心理基础。没有惭愧心,修行者就会违背、超越清净道,堕入生死;有了惭愧心,修行者才能在清净道上不断前进,增长功德,最终关闭生死之门。

五、代表性原文引用

1. 关于八正道即清净道的引用:「正见者为清净道……正志、正语、正业、正命、正方便、正念、正定,是名清净道。」 2. 关于四种清净(净断)的引用:「云何为戒净断?谓圣弟子安住具戒,守护波罗提木叉律仪……云何心净断?谓圣弟子离欲恶不善法,有觉有观,离生喜乐,初禅具足住……云何见净断?若有沙门、婆罗门……入如实正观……」 3. 关于惭愧与清净道关系的引用:「若世间无惭、愧二法者,众生则违越清净道,往来生死,受生老病死、忧悲恼苦;以世间有惭、愧二法故,则能增长清净道,关闭生死门。」 4. 关于批判外道非道求清净的引用:「供养祠祀火,非道求清净,盲无眼目者,不知清净道。于此非道中,而求于寂静,至竟无净时,增长诸苦聚。」

雜阿含經T0099 · 阿含部

《雜阿含經》對「清淨道」的論述,主要從三個側面展開:作為修道實踐的具體內容、與「無上清淨」之果的關係,以及助成此道的因緣條件。

首先,此經將「清淨道」與「無上清淨」明確區分為因與果的兩個層面。經中記載有婆羅門問佛:「何等為清淨道?何等為無上清淨?」佛的回答是:「正見者為清淨道……斷貪欲、斷瞋恚、斷愚癡。若婆羅門貪欲永斷……一切煩惱永斷,是名無上清淨。」 也就是說,「清淨道」是能斷煩惱的修行法,而「無上清淨」則是煩惱永斷所達到的究竟清淨狀態。

其次,此經列舉清淨道的具體內容,涵蓋八項修法:正見、正志、正語、正業、正命、正方便、正念、正定。值得注意的是,此經於八正道第六項用的是「正方便」一詞,與其他經典中常見的「正精進」譯名不同,這是《雜阿含經》特有的用詞形式,應予記錄。經中又特別說明「正定」一項修習多修習之後,能斷貪、瞋、癡三毒,最終達到無上清淨。

第三,經中也指出不知清淨道者的過失:「不知清淨道,及諸無上淨,於餘求靜者,至竟無淨時。」 說明若不依此正修道法而於其他途徑求寂靜,終究無法獲得清淨。又以「非道求清淨,供養祠祀火,不識清淨道,猶如生盲者」 為喻,將不知清淨道而妄求清淨的人比喻為生盲者;唯有依佛所教出家修行、得三明、度彼岸,才是真正走向清淨。

第四,經中亦論及助成清淨道的因緣——慚與愧二法:「世間若無有,慚愧二法者,違越清淨道,向生老病死。世間若成就,慚愧二法者,增長清淨道,永閉生死門。」 說明慚愧能增長清淨道,永閉生死流轉之門;無慚愧則違越清淨道,趨向生老病死。

總之,《雜阿含經》以「清淨道」為能斷煩惱之修法,以「無上清淨」為煩惱永斷之究竟之果;其具體內容為八正道,其中以「正方便」之譯名為此經獨特用詞;並以慚愧為增長此道之重要助緣。

大智度論T1509 · 釋經論部

《大智度論》論「清淨道」,主要從「斷除煩惱、漏盡而得究竟解脫」之義立說,並對比外道種種不圓滿之清淨說法,以顯佛法之殊勝。

一、核心表述:清淨道為斷諸漏、盡煩惱、得解脫之道。論釋阿羅漢果時,以「諸漏已盡」、「無復煩惱」、「心得好解脫,慧得好解脫」三句經文展開。「諸漏已盡」謂三界中三種漏已盡無餘;「無復煩惱」謂一切結、使、流、受、扼、縛、蓋、見、纏等斷除。此解脫不同於外道離欲人「一處一道心得解脫」,而是「於一切障法得解脫」,涅槃道具足圓滿故名「好解脫」;學人雖心得解脫而猶有殘結使,故非「好解脫」。此處以「結、使、流、受、扼、縛、蓋、見、纏」九事總攝煩惱,乃本論獨特之煩惱分類術語。

二、列舉外道「八清淨道」以辨邪正。論中詳列外道所執之清淨道:其一,或但以布施求清淨;其二,祀天言能脫憂衰、得常樂國中生;其三,說「八清淨道」——一自覺、二聞、三讀經、四畏內苦、五畏大眾生苦、六畏天苦、七得好師、十八大布施,然論主明言「但說第八名清淨道」,其餘七項並非究竟之清淨;其四,有外道但以布施、持戒說清淨,或但以布施、禪定說清淨,或但以布施、求智慧說清淨——如是種種道不具足,若無功德、若少功德而說清淨,其人雖一處心得解脫,涅槃道不滿足故不名好解脫。論主以此層層破斥外道之偏執,顯揚究竟清淨道必具足布施、持戒、禪定、智慧等功德。

三、破斥邪師妄說。論中載摩犍提梵志弟子舉其屍著床輿行城市多人處,唱言:「若有眼見摩犍提屍者,是人皆得清淨道,何況禮拜供養者!」多有人信其言,佛因而說偈以破此執著屍身即得清淨道之邪見,明示真正清淨道非由外相恭敬可得。

四、開甘露門之請。論首偈云:「閻浮提先出,多諸不淨法;願開甘露門,當說清淨道!」表閻浮提眾生煩惱垢重,須由佛陀開示甘露法門,演說究竟清淨之修道,方能轉染成淨。

綜上,《大智度論》以「清淨道」一詞貫通「斷煩惱、盡諸漏、得究竟解脫」之義,其獨特側面在於:以「心得好解脫,慧得好解脫」之雙解脫對比外道「一處一道心得解脫」,並列舉外道「八清淨道」及種種偏執之清淨說法,逐一簡別遮破,顯揚唯具足諸功德、涅槃道究竟滿足者,方名真正之清淨道。

瑜伽師地論T1579 · 瑜伽部

《瑜伽師地論》對「清淨道」一詞有多層界定,隨所對根機與修證位次而有不同展開。

一、四清淨道之第四。卷中以四清淨道並列:背惡說法及毘奈耶、向善說法及毘奈耶、資糧道、清淨道。第四「清淨道」自釋為「奢摩他、毘鉢舍那斷諸煩惱現法樂住」。

二、見修究竟三道所攝菩提分法。別就聲聞乘三道(見道、修道、究竟道)而立清淨道,「謂於見道、修道、究竟道中,即彼所攝所有一切菩提分法」。

三、菩薩乘之清淨道。菩薩「方便道」為六波羅蜜多所攝;「清淨道」則為「般若波羅蜜多所攝,此約最勝說,非不一切菩提分法皆遍修習」。

四、五種出世間清淨之第五——極清淨道。卷立「出世間一切種清淨」五種,第五為「證得極清淨道及果功德」。 極清淨道之體為「十無學支所攝五無學蘊」,即戒蘊、定蘊、慧蘊、解脫蘊、解脫知見蘊。 證此道者離十種過失(依外諸欲愁歎憂苦、依內不護諸根、愛味樂住、行住放逸、外道不共邪見語言尋思追求、依靜慮邊際、緣起所攝取雜染品、行雜染品等),住聖所住。 由此煩惱道、後有業道於現法中永斷,當來苦道更不復轉,是名苦邊。

五、清淨道修作之四種差別。就增上心方便立四種清淨道:一、習近正法正審靜慮;二、親事善友;三、以尸羅、根護、少欲等法熏練其心;四、獨處空閑,以奢摩他、毘鉢舍那勝正安樂為翼從。又釋「清淨」者,謂依彼清淨行道多修習故,令有學法破無明㲉,趣無學地。

六、觀察行相之清淨道出離。學位以五種行相審諦觀察,其一為「趣向清淨道出離故」。

七、與清淨道相關之術語。此論以「樂斷煩惱、樂修正道」明修道意樂;以「清淨天性」說天趣,四證淨名「天路」;四證淨為依,諸聖弟子依三種門修六隨念,斷奢摩他品、毘鉢舍那品之隨煩惱,並遮未來當起之二隨煩惱。 又立十種「制立學處清淨」(道理、果、攝受、外、內、具分、愛敬、伏對治修、隨眠斷對治修、相續不斷清淨),並別列勝行、勝命、同法共住、無違諍、制伏煩惱、煩惱離繫、任持正法等清淨。

此論所用術語形式值得注意:清淨道之異稱有「極清淨道」、「清淨行道」;修法特重「奢摩他、毘鉢舍那」並舉;菩薩清淨道特指「般若波羅蜜多」;以「無漏法」、「無學蘊」、「聖所住」等標其究竟。
