What This Concept Is Saying

In Buddhist philosophy, the concept of Karma-patha (業道, literally "the course or pathway of action") occupies a pivotal position in understanding how sentient beings shape their reality and navigate existence. To understand *Karma-patha*, one must first distinguish between Karma (業) and Karma-patha (業道).

According to Abhidharma literature such as the *Abhidharmakośa* (俱舍論) and foundational Mahāyāna scriptures like the *Mahāratnakūṭa Sūtra* (大寶積經), *Karma* refers fundamentally to volition (*cetanā*, 思)—the subtle mental impulse or intention that initiates action. *Karma-patha*, however, represents the explicit, prominent pathways or avenues through which this volition acts, reaches completion, and builds a dedicated highway leading toward corresponding states of suffering or happiness in future existence. Just as a traveler needs a defined road (*patha*) to reach a distant destination, mental volition utilizes specific channels of body, speech, and mind to forge consequences.

The scripture *Mahāratnakūṭa Sūtra* systematically organizes these pathways into the Ten Unwholesome Courses of Action (*daśa-akuśala-karma-patha*, 十不善業道 or 十惡業道) and their exact polar opposites, the Ten Wholesome Courses of Action (*daśa-kuśala-karma-patha*, 十善業道). The text summarizes this structure in the famous verse: *"Three arise from the body, four are born of speech, and the mind completes the three evils."* (三種由身起,四種語業生,意能成三惡)

These ten avenues are defined with absolute precision:

1. The Three Pathways of Body (身三業)

* Taking Life / Killing (*prāṇātipāta*, 殺生 / 奪命): The deliberate, unprovoked destruction of the physical life of a living, sentient being. * Taking What Is Not Given / Stealing (*adattādāna*, 偷盜 / 不與取): Taking possession of property, wealth, or rights belonging to another without their explicit consent, through force, stealth, fraud, or coercion. * Sexual Misconduct (*kāmamithyācāra*, 邪淫 / 邪婬): Engaging in sexual conduct that inflicts emotional or relational harm, violates commitments, or involves forbidden, non-consensual, or inappropriate contexts.

2. The Four Pathways of Speech (語四業)

* False Speech / Lying (*mṛṣāvāda*, 妄語): Intentionally uttering falsehoods to deceive others or distort truth. * Divisive Speech / Slander (*paiśunyavāda*, 兩舌 / 離間語): Speaking in a way that breaks existing harmony, causes division among friends, or deepens conflict between parties. * Harsh Speech / Abuse (*pārūṣyavāda*, 惡口 / 麁語): Uttering words driven by anger, malice, or contempt designed to hurt, humiliate, or provoke emotional agony in others. * Frivolous Speech / Idle Chatter (*saṃbhinnapralāpa*, 綺語): Engaging in meaningless, sensationalist, distracting, or unwholesome talk that dissipates mental clarity and incites latent afflictions.

3. The Three Pathways of Mind (意三業)

* Covetousness / Greed (*abhidhyā*, 貪欲 / 貪著): The active mental obsession and intense longing to appropriate others' possessions, status, or attributes as one's own. * Ill Will / Malice (*vyāpāda*, 瞋恚): A mind infected with animosity, resentment, or the desire to see others suffer harm or destruction. * Wrong View / Delusion (*mithyādṛṣṭi*, 邪見 / 癡): Denying the fundamental law of cause and effect (karma), rejecting the reality of spiritual awakening, or holding dogmas that glorify harm and deny interbeing.

Classical Nuances and Variations

Across different translations of the *Mahāratnakūṭa Sūtra* (such as Bodhiruci's Tang Dynasty translation), textual nuances reflect how these pathways are contemplated: 1. Descriptive Names: In some passages, unwholesome actions are named directly by their destructive act—such as *Depriving of Life* (奪命), *Taking what is not given* (不與取), and *Harsh Utterance* (麁語). In others, conventional names like *Killing* (殺生), *Stealing* (偷盜), and *Abuse* (惡口) are used. 2. Positive Counterparts: When describing the *Ten Wholesome Courses of Action*, the scripture does not merely present passive non-action (e.g., "not killing"); it pairs abstention with active virtues—such as pairing *Non-killing* with active *Loving-kindness / Benevolence* (仁慈), turning abstention into a dynamic force of protection. 3. Abhidharmic Distinction: Early schools like the Sarvāstivāda make a subtle structural distinction: the seven bodily and verbal pathways are both *karma* (action) and *karma-patha* (pathway of action), whereas the three mental pathways (greed, ill will, wrong view) are fundamentally afflictions (*kleśa*) that act as the *pathway* upon which mental volition operates.

The Paradox of Emptiness and the Path to Transcendence

Crucially, the *Mahāratnakūṭa Sūtra* elevates *Karma-patha* from a moral code to an entry point for ultimate wisdom (Ultimate Truth, *paramārtha-satya*). The sūtra reveals:

*"Since there is ultimately no inherent 'self' or 'living being', there is ultimately no inherent 'killer' or 'act of harming'. The remaining nine courses of action are likewise... They possess no self-nature, for their intrinsic nature is tranquil and empty (自性空寂)."*

However, the sūtra immediately adds that this emptiness does not destroy the conventional efficacy of cause and effect (*不壞法體性*). Karma operates like an echo or a shadow: precisely because phenomena lack rigid, unchangeable self-nature, cause seamlessly produces effect.

When a practitioner thoroughly penetrates this truth, subduing all afflictions and transcending the pull of *Karma-patha*, they achieve what the text calls "Leaving the Course of Action" (離業道). The *Mahāratnakūṭa Sūtra* offers a striking classical metaphor for this state:

*"If one leaves the course of action behind, one becomes a Stūpa (Shrine/Caitya) of the World (若離業道已,則為世間塔)."*

Just as an ancient Buddhist stūpa stands serenely amidst the elements—unpolluted by surrounding dust, housing sacred relics, and inspiring reverence in passersby—a person who has dismantled the ten unwholesome pathways becomes a living sanctuary. Untouched by the pull of worldly delusion, their presence naturally clarifies the minds of others and shines as a monument of liberation.


Walkthrough in Daily Life

To understand how *Karma-patha* functions, we do not need ancient battlefields or monastic huts. Our everyday routines—commuting, scrolling on smartphones, managing workplace stress, navigating intimate relationships, and parenting—are saturated with the ten pathways. Let us trace how these pathways quietly open up in contemporary life:

1. The Morning Commute & Work Communication (Speech & Mind Pathways)

* The Scenario: You are stuck in bumper-to-bumper traffic, or someone abruptly cuts you off on the subway. * The Unwholesome Pathway: A flash of rage hits. You slam the horn and mutter a harsh curse under your breath (Harsh Speech / 惡口). You begin to wish the other driver crashes further down the road (Ill Will / 瞋恚). * The Mismapping: People often assume, "I didn't hit their car, so no harm was done." But in the framework of *Karma-patha*, the mental channel of *Ill Will* and the speech channel of *Harsh Speech* have already reached completion in your mind. You have carved a deeper neural and karmic groove of hostility, conditioning your mind to react with anger in future crises. * The Wholesome Pathway: Recognizing the spike of annoyance, you deliberately pause, take a deep breath, and think: "They might be rushing to an emergency. May they arrive safely." (Non-ill Will & Benevolence / 不瞋與仁慈).

2. Scrolling Social Media & Algorithmic Feeds (Speech & Mind Pathways)

* The Scenario: You are lying in bed at night, mindlessly scrolling through short videos or social media platforms. * The Unwholesome Pathway: * You see a colleague post photos of their extravagant vacation or recent career promotion. A sudden pang of bitter envy grips you; you hope their project fails (Covetousness & Envy / 貪著與嫉妬). * You read a controversial political post. Without checking the facts, you write an inflammatory comment designed to pit two groups against each other (Divisive Speech / 兩舌). * You spend three hours watching trivial celebrity gossip and rage-bait videos, consuming mental junk (Idle Chatter / 綺語). * The Mismapping: Modern digital culture frames idle chatter and online trolling as "harmless entertainment" or "harmless venting." In reality, *Frivolous Speech* (*綺語*) is one of the most insidious pathways. It quietly destabilizes mindfulness, dissipates mental concentration, and primes the mind for deeper afflictions. * The Wholesome Pathway: You close the app, acknowledge your envy with compassion, and silently wish your colleague genuine success (Non-covetousness / 不貪). You decide to read a meaningful book or practice meditation instead.

3. Overtime, Workplace Politics & Business (Body, Speech & Mind Pathways)

* The Scenario: Under intense pressure to meet quarterly sales targets, you consider how to present a product to a client. * The Unwholesome Pathway: * You subtly exaggerate product features while concealing critical flaws (False Speech / 妄語). * You claim credit for a junior team member's research, misappropriating their intellectual work (Stealing / 不與取). * You adopt the worldview that "morality is for the weak; only power and money matter" (Wrong View / 邪見). * The Mismapping: Corporate culture often labels misrepresenting facts as "strategic marketing" or "business savvy." From the perspective of *Karma-patha*, stealing is not restricted to robbing a bank; taking credit, time, or resources that do not belong to you completes the pathway of *Taking What Is Not Given*. * The Wholesome Pathway: You communicate transparently with the client about both the strengths and limits of your product (True Speech / 不妄語), and explicitly highlight your team members' contributions (Non-stealing / 不偷盜).

4. Intimate Relationships & Parenting (Body & Speech Pathways)

* The Scenario: You are exhausted after work, and your partner or child makes a mistake at home. * The Unwholesome Pathway: * You lash out with sarcastic, belittling comments aimed at cutting their self-esteem (Harsh Speech / 惡口). * Out of emotional dissatisfaction, you seek secret, inappropriate flirtation or infidelity outside your commitment (Sexual Misconduct / 邪淫). * The Mismapping: People frequently confuse "setting boundaries" with *Harsh Speech*. Screaming or insulting someone to vent anger is an unwholesome pathway of speech; setting a firm, firm boundary with a calm, clear mind is not. * The Wholesome Pathway: You take a moment to regulate your nervous system, speak with gentle firmness (Gentle Speech / 不惡口), and address the behavior while affirming your love for your family.


Why Contemporary People Need It

In our modern world, humans possess unprecedented technological power. An internet post can reach millions in seconds; a single automated algorithm can broadcast outrage across continents. Yet, our emotional equipment remains largely unchanged from ancient times. We are equipped with hyper-efficient tools that magnify our ten pathways of action exponentially.

Contemporary readers need the framework of *Karma-patha* for three essential reasons:

1. A Blueprint for Mental Hygiene in the Attention Economy

Modern digital architecture—personalized algorithms, notification badges, viral mechanics—is explicitly engineered to capitalize on three specific unwholesome pathways: Covetousness (stimulating consumer desire), Ill Will (triggering outrage and tribalism), and Frivolous Speech (hooking users on endless, low-value distraction).

Without a clear ethical framework like *Karma-patha*, we drift through life as passive subjects of algorithmic manipulation. *Karma-patha* acts as a internal firewall. It gives us a precise diagnostic checklist to evaluate our digital inputs and outputs: *Is this post false? Is it divisive? Is it born of malice? Is it idle chatter?* By observing the ten doors of action, we reclaim autonomy over our consciousness.

2. Cognitive Science Analogy and Its Limitations

Contemporary neuroscience often speaks of neuroplasticity—the principle that "neurons that fire together, wire together." Every time you indulge in anxious rumination or angry outbursts, you strengthen specific neural pathways, making those emotional states easier to trigger in the future.

*Karma-patha* can be understood as the spiritual and existential depth of neuroplasticity. When the Buddha spoke of "pathways of action," he was describing how repetitive volitions build deep cognitive and karmic grooves that dictate our perception of reality.

*Important Distinction*: While cognitive science explains the *biological mechanics* of habit formation within a single lifetime, Buddhist *Karma-patha* encompasses a far broader existential dimension. It accounts for the deep moral architecture of consciousness, interbeing, and the trajectory of life beyond immediate physical processes. Science analyzes the structural changes in the brain; *Karma-patha* illuminates the ethical trajectory of the mind and its fruit (*vipāka*).

3. Moving from Passive Victims to Active Designers of Fate

Many contemporary individuals suffer from a pervasive sense of powerlessness, feeling swept along by societal anxieties and economic pressures. Understanding *Karma-patha* transforms our orientation toward life. It teaches that our future environment and internal well-being are not random accidents, nor are they dictated by a external deity. They are the cumulative fruit of how we navigate the ten pathways every single day. Every choice at the ten doors is a vote cast for the kind of mind—and world—we will inhabit tomorrow.


Common Misreadings and Clarifications

Misreading 1: "Karma-patha is just a list of moral commandments or religious taboos."

* Clarification: Unlike traditional religious commandments handed down by a divine authority who rewards or punishes, *Karma-patha* describes natural, psychological, and existential laws of cause and effect (*dharmatā*). The Buddha did not "invent" the ten unwholesome pathways; he merely mapped how cause and effect operate in reality. Engaging in killing, lying, or malice inherently destabilizes the mind, generates guilt, creates conflict, and leads to suffering, just as touching fire burns the hand. It is an natural law of cause and fruit, not a penal code.

Misreading 2: "If I only think about greed or anger but don't act physically, no karma is created."

* Clarification: The *Mahāratnakūṭa Sūtra* and classical Abhidharma make it clear that the mind is the ruler of all actions (*意能成三惡*). Mental pathways—*Covetousness*, *Ill Will*, and *Wrong View*—are complete pathways of action in themselves. While physical or verbal actions often carry more immediate visible consequences in the physical world, mental pathways quietly rot the foundation of the mind. Prolonged mental malice or intense covetousness poisons one's emotional life and inevitably spills over into physical and verbal harm.

Misreading 3: "Since Buddhism teaches that everything is Empty (空), Karma and Karma-patha don't really matter."

* Clarification: This is one of the most dangerous traps in Buddhist practice, historically termed falling into "nihilistic emptiness" (*nihilism / 撥無因果*). The *Mahāratnakūṭa Sūtra* explicitly refutes this misconception. The sūtra states that while the ten pathways are indeed *empty of inherent, independent existence* (*自性空寂*), this emptiness is precisely what allows cause and effect to function flawlessly (*不壞法體性*). Because things are not fixed or concrete, actions produce consequences. To claim that emptiness negates karma is a profound misunderstanding of Ultimate Truth.

Misreading 4: "Frivolous Speech (綺語) is just lighthearted social chatter; it isn't really harmful."

* Clarification: In classical Buddhist ethics, *綺語* (idle, deceptive, or mindless chatter) is considered one of the most subtle yet pervasive obstacles to spiritual growth. It does not mean friendly, genuine human connection or light conversation aimed at comforting someone. Rather, it refers to speech born of restlessness, sensationalism, vulgarity, or gossip that lacks truth, purpose, or benefit. Mindless talk scatters mental focus, squanders valuable time, and acts as a primary vehicle for latent greed and aversion to surface unnoticed.

Misreading 5: "Leaving the Course of Action (離業道) means withdrawing from the world and becoming indifferent."

* Clarification: As the *Mahāratnakūṭa Sūtra* illuminates with the metaphor of the Stūpa of the World (*若離業道已,則為世間塔*), transcending the unwholesome pathways does not mean becoming an unfeeling stone or abandoning society. A stūpa stands in the center of the community, open to all, providing shade, peace, and inspiration. One who has cleared their three doors of physical, verbal, and mental affliction remains deeply active in the world—acting with boundless compassion, wisdom, and clarity—yet remains completely unpolluted by worldly dust. They become a living sanctuary where others find safety, calm, and awakening.

一、 定义与核心要义

在《大宝积经》中,“业道”(karma-patha)是指众生引向善恶果报的身、口、意行为途径。业道是业力运作与显现的具体通道,在经中主要以“十不善业道”(或称“十种不善业道”、“十不善”、“恶业道”)与相对应的“十善”为核心展开论述。众生通过身、口、意三业造作善恶行为,这些行为不仅决定了当下的业行属性,更开辟了通往未来相应苦乐果报的道路。

二、 主要阐述

《大宝积经》对业道的阐述主要围绕其分类、三业归属、因果报应以及如来的悉知展开:

首先,在业道的分类与三业归属上,经中明确指出十不善业道是由身、口、意三业所构成的,即所谓“三种由身起,四种语业生,意能成三恶”。具体而言: 1. 身三业:包括夺命(杀生/害命)、不与取(劫盗/偷盗)与邪婬(邪欲行); 2. 语四业:包括妄语、离间语(两舌)、麁语(麁言/恶口)与绮语; 3. 意三业:包括贪着(贪欲)、瞋恚与邪见(或表现为嫉妬、恚、痴)。

其次,在因果报应方面,经中强调这些业道是“由身由言由意恶行之报,是身口意善恶之果”。若众生造作十不善业道,将会“长夜不安,投于地狱饿鬼畜生”,多堕于恶趣之中。相反,若众生能够“护斯三业”或“身行十善”,则能获得极大的福德,得以“生天人间十方佛前,长夜永安无有众患”。

此外,如来以其无上智慧,能够悉知一切众生的业道。经中指出,如来能完全了知众生所行之业道、所造作的种种方便与业,以及众生随其业力所应当感受的轻重苦乐果报。

三、 不同部类与译本的表述差异

在《大宝积经》(唐菩提流志译本)的不同章节中,对于“十不善业道”与“十善业道”具体名相的表述存在着细微而重要的差异。这些差异反映了译者在不同语境下的用词选择:

1. 在经文的某些段落中(如),十不善业道被表述为:“一者夺命、二者不与取、三者邪婬、四者妄语、五者离间语、六者麁语、七者绮语、八者贪着、九者瞋恚、十者邪见”。 2. 在另一处段落中(如),其表述则转为更为常见的:“杀生、偷盗、邪淫、妄语、两舌、恶口、绮语、贪欲、瞋恚、邪见”。 3. 而在阐述十善业道或不犯十恶的语境下(如),经文则采用了否定与德行并重的表述方式:“不杀(仁慈)、不与不取、不为邪婬、不犯妄言、两舌、恶口、绮语、嫉妬、恚、痴”。

通过对比可以看出: - 对于身三业:第一种表述用“夺命”、“不与取”、“邪婬”;第二种用“杀生”、“偷盗”、“邪淫”;第三种则用“不杀(仁慈)”、“不与不取”、“不为邪婬”。 - 对于语四业:第一种用“离间语”、“麁语”;第二、三种则用“两舌”、“恶口”。 - 对于意三业:第一种用“贪着”、“瞋恚”、“邪见”;第二种用“贪欲”、“瞋恚”、“邪见”;第三种则用“嫉妬”、“恚”、“痴”。

四、 与相关概念的关系

1. 业道与空性的关系: 《大宝积经》对业道的论述并未停留于世俗的因果报应,而是进一步上升到第一义谛的层面。经中指出,从根本法性来看,业道具有“自性空寂”的特征。如经云:“既无众生亦无害,自余九业亦如是,无有对治诸善恶,以彼自性空寂故”。然而,这种空寂并非顽空,经中特别强调其“不坏法体性”,即在胜义自性空的同时,世俗因果法则依然历历不爽,二者圆融不二。

2. 离业道与支提(世间塔)的关系: 经中阐明了超越业道的修行途径。众生若能通过修行降伏其心、降伏烦恼,便能够“离业道”。而一旦能够“离业道已,则为世间塔(支提)”。这意味着超越了业道束缚的觉者,将不再受到世间欲尘的染污,并且能够向世间显示烦恼的过失,从而广作饶益众生的事业,如同世间的佛塔一般令人瞻仰与获福。

五、 代表性原文引用

1. 关于三业构成的偈颂: > “三種由身起,四種語業生,意能成三惡。”

2. 关于因果报应与护持三业: > “由身由言由意惡行之報,是身口意善惡之果……投於地獄餓鬼畜生……生天人間十方佛前,長夜永安無有眾患。”

3. 关于业道自性空寂与不坏法体性: > “既無眾生亦無害,自餘九業亦如是,無有對治諸善惡,以彼自性空寂故。”

4. 关于离业道与成支提: > “若離業道已,則為世間塔。”

大寶積經T0310 · 寶積部

本經《大寶積經》(唐菩提流志譯,寶積部)對「業道」一詞的論述,可從四方面加以歸納。

一、以「十不善」明示業道之具體內容

經中直接界定「業道」所指,謂「如來所說十不善,斯等名之為業道」,並列舉其十項:殺生、偷盜、邪淫、妄語、兩舌、惡口、綺語、貪欲、瞋恚、邪見,且以「佛說此等為不善,是諸眾生惡業道」明標其為惡業道。此處所用術語即「十不善」與「惡業道」,與一般經論所稱「十惡業道」內涵一致,唯經文以「不善」而非「惡」為主詞,是本經措辭之一特點。

二、業道與空寂自性之辯證

同段經文緊接指出:「既無眾生亦無害,自餘九業亦如是,無有對治諸善惡,以彼自性空寂故。」謂此十業從勝義諦觀之,自性空寂,無實眾生可被殺害,亦無實傷害可得,餘九業亦然,更無善惡之實體對立。然而「然復非無十力教,以其不壞法體性」,雖自性空寂,並非撥無因果,如來十力之教仍不壞法體。此即本經論業道之獨特側面——空有不二之詮釋。

三、如來遍知眾生業道

經文以偈頌讚歎如來無等之智慧力,其中云:「眾生於此多所失,如來善知彼業道,世尊知彼甚捷利,故佛無比亦無等」。此處「業道」指眾生身口意造作善惡之行為途徑,如來以智慧悉皆善知其差別、輕重、所趣。經中並隨後鋪陳如來遍知眾生隨業所受之種種苦、於六道久住之時、隨煩惱力所起之方便等,皆可歸入如來對業道之徹知。

四、離業道與斷煩惱之關聯

另一段偈頌以修行次第說明離欲、降心、降伏煩惱之過程,謂「若能降煩惱,即得離業道,若離業道已,則為世間塔」,顯示本經將「離業道」視為降伏煩惱之直接果證,其位次等同於堪為眾生所依之「支提」。同段並以貪、瞋、癡、慢四煩惱為對象,強調「念滅眾生惡,解脫彼……心」之支提行,即透過斷煩惱而離業道。

綜合

本經所用術語即「業道」本身,未見別譯異名;其論述涵攝四要點:明示業道即十不善之具體項目;以空有不二詮其自性空寂而不壞因果;強調如來對眾生業道之遍知;以及離業道作為降伏煩惱之究竟果證。

十住毘婆沙論T1521 · 釋經論部

《十住毘婆沙論》以「身口意業道」總攝善、不善造作的行為途徑,依身、口、意三類各列其數:不善身行三種,為奪他命、劫盜、邪婬;不善口行四種,為妄語、兩舌、惡口、散亂語;不善意行三種,為貪取、瞋惱、邪見。善行則是離奪命、離劫盜、離邪婬,離妄語、離兩舌、離惡口、離散亂語,以及不貪取、不瞋惱、正見。論中特別說「身口意業道,是善不善應須論議,令人得解」,顯示其論述兼明善惡兩向。

本論逐項解釋前七種行為。奪命須有他眾生、明知是眾生、故意惱害,並因惱害使其失去壽命而起身業;劫盜是明知物屬於他,生盜心而取物離處,計為己物;邪婬則就受父母、親族、姓、世法或戒法守護之女人、他人婦,以及自妻妾之受戒、懷妊、乳兒或非道等情形,說明貪欲心與身業的成立。妄語是知其實相而覆相、覆心、覆見、覆忍、覆欲,更作異說;兩舌以離別他人為目的;惡口是能令他瞋惱的惡語、害語、苦語、麁語、弊語;散亂語則包括非時、無利益、非法、無本末、無因緣之語。遠離各事,即名相應善行。

在名相方面,《十住毘婆沙論》使用「奪命」與「殺生」兩種說法,口業第四項稱「散亂語」,意業三項稱「貪取、瞋惱、邪見」;其相反善項則稱「不貪取、不瞋惱、正見」。這些是本論呈現業道時的具體術語形式。

本論又以偈言「七業亦業道,三業道非業」辨別「業」與「業道」。殺生、劫盜、邪婬及四種口行共七事,既是能作之業,又因反覆習行而轉增、通至惡趣,故亦名業道;貪取、瞋惱、邪見則是不善業的根本,僅名業道,其相應之「思」才是業。善法亦同:離前七事既是業亦是業道,常修能至人天好處;不貪取、不瞋惱、正見是善業根本,故為業道而非業,其相應思才是業。

最後,本論以四種分別釐清範圍:一、業而非業道,如拳打、鞭杖等不善身業,以及迎逆、敬禮等善身業;二、業道而非業,即後三不善與三善,因前者屬煩惱性、後者屬善根性,皆能發起相應之業;三、亦業亦業道,即殺生、不殺生等前七事;四、非業非業道,即其餘諸法。又說身口業是戒,意業是業而非戒,由此把業道與戒的關係一併納入判別。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》以「業道」一詞貫通身口意三類善惡行為之論述,核心要點如下:

一、業道與惡妙行之攝屬:論中指出十業道攝於惡行、妙行之中,但僅以麁顯易知者為其性。不善中身惡業道不攝加行、後起及飲諸酒等;語、意業道亦各有所不攝;善業道亦復如是。此即業道「唯攝麁品」之義。

二、業道與加行、根本、後起三階:每一業道皆有三分,如殺生之加行(執持價直、牽還養飯等)、根本(正命終時表無表業)、後起(剝截治洗等)。論主明定業道名「唯目初念」,通初後位立餘四名。別解脫戒亦同此理:唯初剎那表及無表,得別解脫及業道名;從第二念已去,不名別解脫、不名業道,名為後起。

三、十業道之名義分析:論以「業道」一名具二義。後三(貪、瞋、邪見)唯是道而非業,以是業之道故立業道名;前七(身三、語四)既是業亦為道,身語業故,亦業之道,思所遊故。業與道不必同類,如火與煙,於世典中俱極成故。離殺等七、無貪等三立業道名,類此應釋。

四、業道之體性辯論:論中詳辯業道之體究為表業、無表業,抑為「微細相續轉變差別」。有宗主張遣他為殺亦成業道,由本加行,法爾能令教者微細相續轉變差別而生,由此當來能感多果;論主判定「即此微細相續轉變差別名為業道」。若執有實無表法別有體生,則反招詰難。

五、業道與思俱轉之數:業道之業即相應之思,「彼相應思說名為業,彼轉故轉、彼行故行」。不善業道與思俱轉一至八,善業道總開至十而別遮一八五。

六、福業事與業道之差別:施戒修三類各隨其所應,如業道之說有業有道有事之別。施類中身語二業具福業事三種義名,戒類皆具受福業事名,修類中慈唯名福事等,與業道之分析互相對應。

七、不律儀之五名:不律儀亦得惡行、惡戒、業、業道、不律儀五名,「根本所攝故名業道」,同樣以初念為限。

《俱舍論》以「業道」一名統合身語意善惡行為之分析,特別強調「唯初剎那」、「唯攝麁品」、「業與道具二義」三項原則,並以之作為十善惡業道分類之綱骨。
