A Contemporary ReadingAI-generated

Regression (Chinese: 退轉; Sanskrit: *vinivartana*) is a pivotal and profound concept in Mahāyāna Buddhism.

At its simplest surface definition, regression refers to a scenario in which a Bodhisattva (菩薩)—a practitioner committed to universal awakening—loses their Great Bodhicitta (大菩提心, the resolve to attain supreme enlightenment to liberate all beings) due to conceptual discrimination, afflictions, or paralyzing fear, subsequently falling into lower spiritual vehicles such as the Voice-Hearer (*Śrāvakayāna* / 聲聞乘) or Solitary Realizer (*Pratyekabuddhayāna* / 獨覺乘) paths.

However, when examined through canonical scriptures—most notably the *Mahāratnakūṭa Sūtra* (《大寶積經》)—regression is revealed not merely as a moral failure or a loss of enthusiasm, but as a subtle cognitive trap. It exposes the ultimate mechanics of the human mind under pressure, the hidden roots of spiritual burnout, and the subtle ego-clinging that masquerades as noble altruism.


What This Concept Is Saying

To understand regression, one must trace its anatomy across four distinct levels: its outward manifestations, its coarse causes, its subtle causes, and its ultimate ontological nature (*dharmatā* / 法性).

1. The Outward Manifestation: Retreat from Universal Vow to Individual Safety

In Mahāyāna doctrine, the highest goal is *Anuttara-samyak-saṃbodhi* (無上正等正覺, Supreme Perfect Enlightenment). A Bodhisattva vows to remain in the world, accepting its turbulence, in order to liberate all sentient beings.

When regression occurs, the practitioner does not necessarily become evil; rather, they shrink their scope. Overwhelmed by the vastness of suffering or their own limitations, they retreat into the "Lower Vehicles" (*Hīnayāna* or *Dvicakra* / 二乘, referring to Śrāvakayāna and Pratyekabuddhayāna). In these paths, the goal shifts from universal liberation to personal peace and individual *Nirvāṇa* (般涅槃). In the canonical view, abandoning the vow to save others in favor of personal escape is the ultimate spiritual regression.

2. The Coarse Causes: Practical Fatigue and External Doubt

The *Mahāratnakūṭa Sūtra* outlines clear, observable causes that trigger this spiritual retreat:

* For Lay Bodhisattvas (在家菩薩): * *Fear of suffering:* A paralyzing dread of lower realms of existence (*怖三惡道*). * *Perceiving Bodhicitta as a crushing weight:* Viewing the vow to help others as an intolerable burden (*對大菩提起重擔想*). * *Regret after generosity:* Experiencing buyer's remorse or mental stinginess after giving time, wealth, or energy (*施後追悔*). * *Spiritual laziness and lack of diligence:* Slipping into passivity (*不勤精進* / *懈怠*). * *Dharma-stinginess and superstition:* Hoarding knowledge (*慳吝於法*) or relying obsessively on worldly omens, luck, and signs (*取世間吉凶之相*). * External Discouragement and Internal Collapse: Listening to critics who claim one's roots of goodness are unstable (*善根未定*) or that one is trapped in cyclic existence (*輪轉五道*), leading to internal despair (*心生退沒*). This is aggravated by failing to study Mahāyāna scriptures, clinging to ego-identity (*貪著吾我*), and lacking a genuine, deep-seated desire to guide others (*不能深心教化他人*).

3. The Subtle Causes: The Trap of Dualistic Conceptualization

Here, the teachings go far deeper. Regression is not caused only by obvious negative states like anger or laziness; it is primarily caused by subtle dualistic discrimination (*prapañca* / 分別).

The scripture reveals that as long as a practitioner holds onto conceptual dualisms, they remain susceptible to retrogression. This includes discriminating between causes, views, names, forms (*nāma-rūpa* / 名色), the three realms (*traidhātuka* / 三界), and taking signs (*取相*) of eternalism or annihilationism.

Most astonishingly, the *Mahāratnakūṭa Sūtra* states that even "holy" or altruistic thoughts are subtle triggers for regression if infected by ego-grasping: * *Generating ideas of a fixed entity:* Grasping at concepts of a self (*āman* / 我想), a living being (*sattva* / 眾生想), a soul/lifespan (*jīva* / 壽命想), or a person (*pudgala* / 福伽羅想, translated in this text with the unique term *福伽羅想*). * *Grasping at aggregates, bases, and elements:* Reifying the five aggregates (*skandha* / 諸陰), the twelve sense-bases (*āyatana* / 諸入), or the eighteen elements (*dhātu* / 諸界). * *Subtle spiritual messiah complex:* Entertaining thoughts such as "I shall become a Buddha" (*我當成佛*), "I shall preach the Dharma" (*我當說法*), or "I shall save sentient beings" (*我度眾生*). The moment an "I" is set up as the savior and "others" as the saved, dualism takes root, paving the way for eventual exhaustion and regression.

4. Non-Regression (*Avaivartika*) and the Ultimate Nature of Retrogression

How does one achieve Non-Regression (不退轉; Sanskrit: *avaivartika* or *avaivartya*)?

* Non-Discrimination is Non-Regression: The sūtra redefines Non-Regression not as an unyielding, rigid willpower, but as the cessation of dualistic discrimination (*不生分別*). A non-regressing Bodhisattva does not reify the Buddha's powers, features, or pure lands, nor do they look down upon lower vehicles or discriminate against those who regress. * Settling in Emptiness: Non-regression is realized by penetrating the Three Gateways of Liberation (*trivimokṣamukha* / 三解脫門): Emptiness (*śūnyatā* / 空), Signlessness (*animitta* / 無相), and Wishlessness/Non-action (*apaṇihita* / 無願 or 無作). * The Emptiness of Regression Itself (The Regression Dharma Gateway / 退轉法門): Bodhisattva Mañjuśrī (*文殊師利菩薩*) delivers the ultimate insight: **Regression itself is neither existent nor non-existent (*非有非無*)**. * To claim that regression definitively exists as a real substance falls into the error of Eternalism (*常邊*). * To claim that regression does not exist at all falls into the error of Annihilationism (*斷邊*). * Regression is simply an illusory appearance resulting from false grasping (*虛妄取*), inverted grasping (*顛倒取*), and improper grasping (*不如取*). Understanding that one's prior burnout or loss of heart was based on an "unreal notion" (*不真實想*) liberates one instantly. This paradox—understanding the emptiness of failure—is called the *Bodhisattva Retrogression Dharma Gateway* (*菩薩退轉法門*).

5. A Nuanced Case: Disrobing as a Conformity with Dharma

The *Mahāratnakūṭa Sūtra* offers a surprisingly compassionate perspective on a monastic "returning home" (退還家 / disrobing). If a monk disrobes because he feels his current practice is inadequate and he honestly wishes to stop consuming offerings from the faithful without merit, the Buddha calls this an act in "conformity with the Dharma" (*順法*). Driven by genuine conscience and repentance, such a person will be reborn in the Tuṣita heaven under Maitreya Bodhisattva and should not be condemned.


A Life Audit

To see how regression plays out in real time, let us walk through common contemporary scenarios step-by-step, mapping them directly to canonical definitions.

``` [Initial Idealism / Vow] ──> [Encountering Friction & Exhaustion] ──> [Subtle Ego-Clinging] ──> [Regression / Burnout] ──> [Wisdom of Non-Discrimination] (Bodhicitta / Great Resolve) (Heavy Burden / Regret / Cynicism) ("I am saving them" Messiah Complex) (Retreat into Cynicism or Solitude) (Emptiness / Non-Regression) ```

Scenario 1: The Open-Source Developer or Social Activist

* The Initial Resolve: You launch an open-source project or join a non-profit social initiative. You vow to build tools or systems that free people from exploitation. * The Coarse Regression: After months of working 80-hour weeks alongside your day job, users leave demanding, ungrateful reviews; toxic online comments attack your motives. You begin to experience "regret after giving" (*施後追悔*) and feel that altruism is a "crushing burden" (*重擔想*). * The Subtle Trap: Why did you burn out? Deep down, you held the subtle conceptual structure: *"I (*我*) am delivering these ungrateful users (*眾生*)."* Because your identity was built on being the hero, their lack of appreciation crushed your resolve. * The Regressed State: You abandon the project, delete the repository, and retreat into cynical isolation. You vow never to help the public again, choosing instead to do the bare minimum at a high-paying corporate job (*falling into a lower, self-protective vehicle*). * Mapping to Correct Interpretation: Retreating to rest is not intrinsically evil. But if you view your past attempt as a total failure or view humanity as inherently irredeemable, you are trapped in dualism (*取相 / 斷常二邊*). Realizing that your initial burn-out came from an "unreal notion" (*不真實想*) of being a solitary savior allows you to return to contributing—without the burden of ego.

Scenario 2: The Idealistic Parent or Educator

* The Initial Resolve: You approach parenting or teaching with deep empathy, vowing to raise mindful, compassionate children without relying on authoritarian coercion. * The Coarse Regression: Years of tantrums, adolescent defiance, and external pressures kick in. Relatives tell you your gentle methods are naive (*听信他人言善根未定*). You panic about their future, fear societal failure (*怖三惡道*), and begin to regret the immense personal sacrifices you made (*施後追悔*). * The Subtle Trap: You were operating on the hidden premise: *"I (*我*) will mould this child (*士夫想 / 眾生想*) into a perfect human."* * The Regressed State: Exhausted, you drop all empathetic engagement and revert to rigid control or emotional detachment ("I don't care anymore, just pass your exams"), seeking only quiet peace for yourself (*聲聞 / 獨覺式的冷漠逃避*). * Mapping to Correct Interpretation: Recognizing that both the child and yourself are dynamic, interdependent processes—not fixed entities to be mastered—shifts your approach from ego-driven control to grounded, non-attached care (*安住法界平等*).

Scenario 3: The Career Change and "Stepping Back"

* The Misapprehension: A professional working at an ethics-focused organization realizes they lack the emotional maturity or skill to handle the role. Feeling like an impostor who takes a salary without delivering real value, they step down to take an ordinary role and work on self-cultivation. * Common Misreading: Colleagues mock them for "giving up on the cause" or "regressing." * Canonical Correction: This mirrors the sūtra's stance on monks "returning home" (*退還家*) out of honesty. Because the move stems from genuine self-awareness and integrity rather than cynical malice, it is a "conforming action" (*順法*) that protects spiritual momentum rather than destroying it.


Why Contemporary People Need It

Modern life is an engine designed to generate spiritual and emotional regression. Contemporary readers need the wisdom of *vinivartana* for three urgent reasons:

1. Deconstructing the "Messiah Complex" in Activism and Leadership

Modern culture praises hyper-individualistic heroism. Whether in tech startups, social justice, or corporate reform, leaders are encouraged to adopt the mindset: *"I am going to save this company/world."* Canonical teachings on regression point out that this exact mindset (*我當成佛 / 我度眾生*) is the primary seed of eventual cynicism and collapse. When we center ourselves as the primary agent of salvation, any failure by others feels like a personal betrayal. The teachings offer a radical alternative: altruism without an ego-center.

2. Antidote to "Moral Fatigue" in the Information Age

Through smartphone screens, contemporary individuals are bombarded with global crises 24/7. This constant exposure triggers what the sūtra calls "perceiving the burden as crushing" (*對大菩提起重擔想*) and "fear of evil realms" (*怖三惡道*). Without a grounding in Emptiness (*śūnyatā*), people oscillate wildly between outrage and total apathy. The doctrine of Non-Regression shows how to remain engaged in the world without drowning in emotional paralysis.

3. Insights from AI and Algorithmic Life (and Their Limits)

In modern technology, we observe dynamic systems: * Reinforcement Learning Analogies: An AI agent trained on an ill-defined reward function can experience catastrophic forgetting or policy collapse—it "regresses" when overwhelmed by unexpected data distribution shifts. Similarly, a practitioner whose reward function is based on "worldly results" or "appreciation from others" will experience catastrophic spiritual collapse when outer conditions sour. * The Limitation of the Analogy: An AI model regresses due to mathematical parameters in silicon; a human practitioner regresses due to subtle, conscious attachments to self-concepts (*āman-saṃjñā* / 我想). While algorithms can be re-trained with data, human mind-streams are liberated by penetrating the nature of reality (*dharmatā* / 法性). Science describes the mechanics of behavioral failure, but Buddhist philosophy provides the internal framework to transcend the illusion of failure altogether.


Common Misreadings and Clarifications

To prevent shallow translations and conceptual misunderstandings, let us clarify four major misconceptions:

| Misreading | Canonical Reality | | :--- | :--- | | 1. Regression means committing a moral crime or evil act. | Regression is primarily a contraction of vision. In Mahāyāna, the core of regression is losing the resolve for universal liberation and shrinking back into individual self-preservation (*Śrāvakayāna* or *Pratyekabuddhayāna*), even if one lives a morally blameless life. | | 2. Non-Regression means unyielding, stubborn willpower. | **Non-Regression is non-discrimination (*不生分別*).** It is not about gritting one's teeth through sheer grit. True non-retrogression comes from realizing emptiness (*śūnyatā*), signlessness (*animitta*), and wishlessness (*apaṇihita*)—letting go of dualistic fixations. | | 3. Stepping back or disrobing is always a total failure. | **Honest retreat can be a Dharma-conforming action (*順法*). As shown in the case of monastics returning home due to conscientious self-awareness, stepping back out of integrity and repentance is praised over hypocritical persistence. | | 4. Regression is an inherent, permanent mark of shame. | Regression is empty and lacking inherent existence (*非有非無*).** Viewing regression as an unchangeable real event falls into Eternalism (*常邊*); ignoring its real-world manifestation falls into Annihilationism (*斷邊*). It is merely an illusory state arising from misperception (*不真實想*). |


Summary

To study Regression (*vinivartana*) is to receive a masterclass in sustainable compassion. It warns us that the greatest danger to any noble endeavor is not just outer opposition, but the subtle, unexamined ego within our own idealism.

When we drop the subtle compulsion to be the grand savior (*我度眾生*), step away from dualistic demands for worldly validation, and rest in the spacious, open nature of reality (*dharmatā*), we discover the secret to Non-Regression: a heart that can walk into the fires of the world again and again, without ever burning out.

Canonical EntryAI-generated

一、 定义与核心要义

在《大宝积经》中,「退转」(vinivartana)是指菩萨在修行过程中,因种种内外因缘、分别执着或心生惊畏,从而退失大菩提心,退堕至声闻、独觉等下劣乘位的现象。然而,从深层的法性本质来看,退转并非实有,而是「非有非无」的空性显现。若能不生分别、通达佛慧,安住于空、无相、无愿等法性之中,即能证得「不退转」。

二、 主要阐述

《大宝积经》对退转的表现、因由、不退转的证得,以及退转的法性本质进行了多角度的系统阐述:

1. 退转的表现与因由 菩萨退转的核心表现是退失大菩提心,退堕至声闻、独觉等二乘位。经中详细列举了导致退转的具体因由: - 在家菩萨的退转因缘:在家菩萨若成就「怖三恶道、对大菩提起重担想、施后追悔、不勤精进」等法,会退失菩提而于声闻乘中般涅槃;若成就「悭吝于法、取世间吉凶之相、懈怠」等三法,则会退失菩提而于独觉乘中般涅槃。 - 外在言说与内心退没:菩萨若听信他人言其「善根未定、轮转五道」而心生退没,或因不闻菩萨经、贪着吾我、不能深心教化他人等四法,亦会退失菩提成声闻乘。 - 微细的分别与执着:退转存在极为微细的因由。从根本上说,一切分别与执着皆是退转的根源,包括对因、见、名、色、三界(欲界、色界、无色界)、声闻行、辟支佛行,以及分别、执着、相、取相、断常见、取舍的执着;乃至生起我想、众生想、寿命想、士夫想、福伽罗想、思想、系缚、颠倒、我见、诸盖、诸阴、诸入、诸界等想。甚至菩萨若生起「我当成佛、我当说法、我度众生」等微细想,亦会导致退转。此外,行于烦恼者,不能生起白法,必定会导致修行上的退减。

2. 不退转的定义与证得 与退转相对,经中对「不退转」进行了超越常规的界定。不退转并非在外相上有所得,而是「不生分别」。若菩萨能不分别如来十力、四无所畏、十八不共法、一切根力觉道、相好、庄严佛国、声闻、菩萨,乃至不分别一切分别退转者,才被称为真正的「不退转」。 菩萨欲证得不退转,应当通达佛慧,从空、无相、无愿、如如、法性、实际、平等中去证得。若信乐心决定者,则终无退转之意。若能安住于功德法门,于法性中当得不退转。

3. 退转的法性本质(退转法门) 文殊师利菩萨深入阐述了退转的空性本质,指出退转是「非有非无」的。若认为有法可退转,则堕于「常边」;若认为无法可退转,则堕于「断边」。退转本质上是由于虚妄取、颠倒取、不如取所致。若能对先前的「不真实想」予以证知,即是非断非常,这被称为「菩萨退转法门」。对于初发心菩萨而言,若惊畏声闻缘觉地,则便退转;若能安住法界平等,修行空、无相、无作,解一切法无生无灭,则名为善住。

三、 不同部类与译本的表述差异

在《大宝积经》(唐菩提流志译)中,存在一些独特的译名与术语表述: 1. 独特术语:在论述退转的微细因由时,该经使用了特定的译名。例如,以「福伽罗想」指代其他经论中常见的「补特伽罗想」(pudgala);以「诸阴」指代「五阴」或「五蕴」(skandha)。 2. 「退还家」的顺法论述:对于比丘「退还家」(即舍戒还俗)的现象,该经提出了独特的看法。佛陀认为,若比丘是因为不欲受人信施而选择退还家,此乃「顺法」之行。彼等因信解心多而生起悔心,命终之后将往生兜率天弥勒菩萨处,因此不应对其加以呵责。

四、 与相关概念的关系

1. 与「菩提心」的关系:退转的直接表现即是退失大菩提心。菩萨若生起怖畏、追悔、懈怠等心,或听信他人言其善根未定,便会退失菩提心而堕入二乘。 2. 与「二乘(声闻、独觉)」的关系:在《大宝积经》的框架下,退转的主要去向即是声闻乘与独觉乘。退堕声闻或独觉乘般涅槃,被视为菩萨修行路上的最大退转。 3. 与「三解脱门(空、无相、无愿)」的关系:三解脱门是证得不退转的关键途径。菩萨只有通达佛慧,从空、无相、无愿等法性中,以及修行空、无相、无作(无愿),解一切法无生无灭,才能真正安住而不退转。 4. 与「分别、执着」的关系:分别与执着是退转的根本因缘。无论是对三界、二乘行的执着,还是对「我当成佛、我度众生」等微细法相的分别,皆会导致退转;反之,「不生分别」即是不退转。

五、 代表性原文引用

1. 关于在家菩萨退堕二乘:「复有三法退失菩提,于声闻乘而般涅槃。何等为三?一者怖三恶道,二者于大菩提起重担想,三者施已追悔不勤精进。」 2. 关于退转的微细因由与不退转:「若分别因、分别见、分别名、分别色……分别我想、众生想、寿命想、士夫想、福伽罗想、思想、系缚、颠倒、我见、诸盖、诸阴、诸入、诸界……乃至分别我当成佛、我当说法、我度众生,如是等皆名为退。若不分别如来十力……乃至不分别一切分别退转者,是名不退转。」 3. 关于退转的法性本质:「退转者非有非无。若有法退转则堕常边,若无法退转则堕断边。文殊师利!退转者,虚妄取、颠倒取、不如取。若能于先不真实想而证知者,即是非断常,是名菩萨退转法门。」 4. 关于初发心菩萨的退转与安住:「初发心菩萨,若惊怖畏声闻辟支佛地,是便退转;若能安住法界平等,修空、无相、无作,解一切法无生无灭,是名善住。」

小品般若波羅蜜經T0227 · 般若部

《小品般若波羅蜜經》論「退轉」,環繞般若波羅蜜為防退之本而展開,可條述如下:

一、退轉之相與墮處:經以「中道退轉」明示菩薩已發無上正等覺心,具信乃至精進,卻於未得薩婆若之前退失大寶,墮於聲聞、辟支佛地;所失之「大珍寶」即薩婆若寶。

二、般若方便為防退樞紐:菩薩雖有信與精進,若「不為般若波羅蜜方便所護」,則中道沒退;若「為般若波羅蜜方便所護」,則不中道退轉,能至阿耨多羅三藐三菩提。

三、二喻明不退之理:(一)以「百二十歲老病之人」為喻,明菩薩雖發心而力弱,須二人各扶一腋、安慰相扶持,方能遠行不退;(二)以「莊治堅牢、推著水中、載諸財物之船」為喻,明如是菩薩不中道沒,隨所至處必得。

四、以空破退轉之難:舍利弗以「恒河沙等諸菩薩不應退轉」為難,須菩提即以色、受、想、行、識,乃至諸法之「如」一一反問,明「於阿耨多羅三藐三菩提退轉」者畢竟不可得,以一切法空故、無法可得故。

五、三乘一如與不退之心:於如中三乘差別不可得。若菩薩聞此不驚、不怖、不沒、不退,當知是菩薩則能成就無上菩提;佛亦讚此為成就菩提之相貌。

六、阿毘跋致之深義:經另用「阿毘跋致」一詞稱不退轉菩薩,其相貌即是深般若波羅蜜相,亦即是空、無相、無作、無起、無生無滅、無所有、無染寂滅、遠離涅槃之義。菩薩若能如深般若波羅蜜教思惟學習,乃至一日,則離退轉過惡,捨生死之難。

七、行般若波羅蜜即名不退:「菩薩如是學者,得近薩婆若」即名為「不退於薩婆若」,遠聲聞、辟支佛地,近阿耨多羅三藐三菩提。其行法要在「不分別般若波羅蜜、不見般若波羅蜜、不言此是般若波羅蜜」,如是方為真行。

八、結斷之辭:經末以斷語總收,云「若菩薩如是行,如是念,於阿耨多羅三藐三菩提退轉者,無有是處」。

本經用詞特色:正面以「阿毘跋致」「不退」明不退之德,反面以「退轉」「中道退轉」「中道沒」明退失之相;以「薩婆若」指所證之智,以「般若波羅蜜方便所護」為防退之關鍵,全經以「般若波羅蜜」為不退之根本所依而立說。

大寶積經T0310 · 寶積部

本經(《大寶積經》)論「退轉」,意指從已得善法或修證階位中退失。「退轉」與「不退轉」之語散見於不動如來會及文殊師利會,茲歸納如下:

一、退轉之緣起——廣列種種。文殊師利對善住意天子廣說退轉之因:由因、見、名、色;由欲界、色界、無色界;由聲聞行、辟支佛行;由分別、執著、相、取相;由斷見、常見;由取、捨;由我想、眾生想、壽命想、士夫想、福伽羅想;由思想、繫縛、顛倒;由我見及以我見為根本之六十二見;由諸蓋、諸陰、諸入、諸界;由佛想、法想、僧想;乃至由「我當成佛、我當說法、我度眾生、我當破魔、我得智慧」諸想,皆可有退轉。 經中以「福伽羅」譯 pudgala,與常見之「補特伽羅」用詞不同,可資參照。

二、初發心菩薩之辨示。文殊師利云:初發無上菩提心者,聞甚深法生於驚畏便當退轉;驚畏聲聞緣覺之地亦便退轉。 偈頌亦云:「彼等求佛心,終不有退轉,欣喜微妙心,聞佛善說故。」 復云:「佛吼無畏時,所說不可毀,信樂心決定,終無退轉意。」 此以信樂決定、欣喜微妙為不退之因。

三、「住於不退」之反顯語。文殊師利言:「若有菩薩初發道心驚畏聲聞緣覺地,則便退轉。若慳惜破戒瞋怠亂癡,住於不退。」此以反顯之語辨明:驚畏大乘而退轉者為真退轉;具慳、破戒、瞋、怠、亂、癡之相者,反令其住於不退之位。 又說初發心菩薩若安住於法界平等之中,是名「善住」。

四、不退轉之因行。文殊師利云:若不分別如來十力、四無所畏、十八不共法、根力覺道、諸相好、莊嚴佛國、聲聞、菩薩,乃至不分別一切分別退轉者,是名不退轉。又明:從通達佛慧故得不退轉;從空、無相、無願、如如、法性、實際、平等故不退轉。 不動如來會亦云:「菩薩摩訶薩住此法門,於法性中當不退轉。」 並勸菩薩「於無上菩提不應生於退轉之相」。

五、退轉之體性——非有非無。善住意問退轉為有法耶?為無法乎?文殊答:「非有非無如是退轉。」 退轉之性不可定執。若有法退轉則墮常邊,無法退轉則墮斷邊;世尊說法不住常、不住斷,非斷非常。 若有若無之見,是虛妄取、是顛倒取、是不如取。如此方名「菩薩退轉法門」。說是法時,十千天子得無生法忍。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》對「退轉」(即退、失、退失)之論述,可從捨善根之緣、聖者退轉之理、阿羅漢果退與不退之諍、退轉之種別、及退轉與染淨之關等五方面歸納。

一、捨善根之緣與退轉。論以「捨定生善法,由易地退等,捨聖由得果,練根及退失」頌明:靜慮地所繫善法之捨有二緣——易地(從下地生上地或上地沒來生下地)與得退(已獲勝定功德還退失時)。「失退二捨非得為性,退必起過,失不必然」明示退與失同為捨之性,然退必起過失,失則未必。無漏善法之捨另有三緣:得果、練根、退失。

二、聖者退轉之理。論以「經欲界生聖,不往餘界生,此及往上生,無練根并退」頌示,經欲界生或已往上界生之聖者,必無練根與退轉,因經生習根極成熟、得殊勝所依止故。關於見斷與修斷煩惱能否生退,論明「諦理真實,揩定可依,聖慧已證必無退理」,而「事相浮偽無定可依,斷迷彼惑有失念退」。見所斷惑由審慮生推度性故,聖若審慮便見諦理,故見斷定無退義;修所斷惑非審慮生、由失念或昧鈍性故,聖有退起。

三、阿羅漢果退與不退之諍。論中存毘婆沙師與經部師之別。毘婆沙師定說阿羅漢果亦有退義;經部師則以教理證阿羅漢亦無退義,引「我說有學應不放逸,非阿羅漢」等經為證,認為所退者為現法樂住等,非果性解脫。

四、退轉之種別。論以「應知退有三,已未得受用」頌立三退:已得退(退已得殊勝功德)、未得退(未能得殊勝功德)、受用退(已得功德不現在前)。佛陀具眾德、無容頓現前故,唯有受用退;不動法具有受用退及未得退;其餘五種性容具三退。

五、退轉與染淨之關。論言「淨由離染生,無漏由離染,染由生及退」,明染法由生及退而得,顯示退轉為染法生起之緣。

論中用詞以「退」、「退失」為主,未另立特殊譯名;退轉涵蓋定善、勝定功德、無漏果道、現法樂住等多層次之失壞,並以「失念」、「昧鈍」說明修惑退起之理。
