What This Concept Is Talking About

In Buddhist philosophy, 緣生 (*pratītyasamutpanna* — dependently arisen phenomena) is not merely an abstract doctrine; it is the universal law governing all conditioned reality. At its core, the term describes a precise phenomenon: all physical and mental phenomena (*dharmas*, 諸法) arise in reliance upon a convergence of causes (*hetu*, 因) and conditions (*pratjaya*, 緣). When these causes and conditions gather, a phenomenon emerges; when they disperse, the phenomenon dissolves.

To understand *緣生*, one must locate it within the broader framework of the path to liberation (*vimukti-mārga*, 解脫道). In the early discourses such as the *Samyukta Āgama* (《雜阿含經》), the Buddha presents *緣生法* (dependently arisen phenomena) alongside *因緣法* (the principle of dependent origination itself, *pratītyasamutpāda*). While *pratītyasamutpāda* refers to the immutable principle—*"When this exists, that comes to be; with the arising of this, that arises"*—*緣生法* (*pratītyasamutpanna-dharma*) refers to the actual, concrete phenomena that are produced through this dynamic.

The classical texts define the full scope of dependently arisen phenomena through the Twelve Links of Dependent Origination (*dvādaśāṅga-pratītyasamutpāda*, 十二因緣): 1. Ignorance (*avidyā*, 無明): Unawareness of reality and the Noble Truths. 2. Volitional Formations (*saṃskāra*, 行): Mental intentions and karmic fabrications. 3. Consciousness (*vijñāna*, 識): Cognition through sensory and mental awareness. 4. Name-and-Form (*nāmarūpa*, 名色): The physical body (*rūpa*) and mental components (*nāma*: feeling, perception, intention, contact, attention). 5. Six Sense Bases (*ṣaḍāyatana*, 六入處): The internal sense faculties (eye, ear, nose, tongue, body, mind). 6. Contact (*sparśa*, 觸): The meeting of a sense organ, its corresponding object, and consciousness. 7. Feeling (*vedanā*, 受): The raw affective tone of experience (pleasant, unpleasant, or neutral). 8. Craving (*tṛṣṇā*, 愛): The thirst or impulse to pursue pleasure or avoid pain. 9. Clinging (*upādāna*, 取): Grasping onto objects, views, routines, or a sense of self. 10. Becoming (*bhava*, 有): The dynamic impulse or state of existence that propels future birth. 11. Birth (*jāti*, 生): The manifestation of a new life or state of consciousness. 12. Aging, Illness, Death, Grief, and Suffering (*jarā-marana-śoka-paridevāna-duḥkha*, 老病死憂悲惱苦): The mass of suffering inherent in conditioned existence.

The Buddha observed that whether a Buddha appears in the world or not, this truth remains permanent and unalterable: *"This principle is constant; it abides in the realm of reality"* (*此法常住,法住法界*). It possesses the characteristics of being stable (*法住*), empty (*法空*), such (*法如*), natural (*法爾*), untruthful of distortion, and thoroughly real.

To illustrate how conditioned phenomena arise and pass away, the *Samyukta Āgama* provides explicit, structured similes that must not be generalized:

* The Tree and the Shadow Simile: In the *Samyukta Āgama*, the text compares internal sense bases and external sense objects (*外六入處*, external sense fields) to a great tree. A tree depends on roots, trunks, branches, and leaves. So long as the roots and trunk exist, the tree casts a shadow. But if the roots are severed and the wood is chopped down, the shadow vanishes without a trace. Similarly, pleasant and unpleasant feelings are not self-existent entities; they are like the shadow cast by the tree of sense bases and objects. When the object or the sense organ ceases, the resulting feeling instantly dissolves. * The Seed and the Four Elements Simile: Just as a plant seed relies on the earth (*pṛthivī*), water (*āp*), fire (*tejas*), and wind (*vāyu*) to sprout, our physical form (*此形*, the body) and the five aggregates, eighteen elements, and twelve sense spheres (*陰界入*, *skandha-dhātu-āyatana*) do not arise spontaneously or through a divine creator. They are strictly *"born of the harmonious gathering of causes and conditions, and wear away upon their separation"* (*因緣和合生,緣離則磨滅*).

As Mahāyāna texts like the *Māhāratnakūṭa Sūtra* (《大寶積經》) and *Mahāsaṃnipāta Sūtra* (《大方等大集經》) deepen this teaching, they highlight a radical insight: **Dependent Arising is itself Unarisen (*緣生即無生*)**.

When we closely examine how causes (*hetu*) and conditions (*pratjaya*) produce an outcome, we find that the effect does not pre-exist in the cause, nor does it exist in the condition, nor does it exist in a gap between them. For example, in the case of Contact (*sparśa*, 觸), touch only exists as a word and nominal concept; its inherent nature cannot be found. Because an effect relies entirely on factors other than itself to appear, it lacks an independent, intrinsic core (*svabhāva*, 自性). Therefore, to say something is "dependently arisen" is identical to saying it is "unborn" (*anutpāda*, 無生) and "empty of self-nature" (*niḥsvabhāva*, 無自性).

This insight is central to the entire path of liberation: * The Wheel of Suffering: When conditions are present, the wheel of suffering turns (*眾緣有故苦綸運*). * The Cessation of Suffering: When conditions cease through wisdom, the wheel of suffering stops (*眾緣無故苦綸斷*). * As Venerable Aśvajit (translated as *馬星* in North Liang texts) famously summarized to Śāriputra (*優波提舍*): *"All phenomena arise from conditions; the Tathāgata has explained their cause. Their cessation is also explained by him; this is the teaching of the Great Renunciate"* (*法從緣生,通達是因,因緣滅故,即是寂靜*).


A Walkthrough in Daily Life

To truly grasp *緣生*, we must move past abstract vocabulary and trace how these twelve links and sensory dynamics unfold in modern daily routines. The key is to map each phase precisely according to its canonical definition—avoiding the common error of confusing distinct psychological stages.

1. Morning Commute & Notification Alert

* **Sensory Contact (*觸*, *sparśa*)**: You are sitting on a crowded subway train. Your smartphone buzzes in your hand. Canonically, *Contact* is not just physical touch; it is the exact instant when three factors meet: the physical eye/ear (*eye/ear sense base*), the glowing screen/chime (*sense object*), and visual/auditory consciousness (*vijñāna*). * **Feeling (*受*, *vedanā*)**: You glance at the screen and see an urgent email notification from your manager with the subject line: "Need to talk about your project ASAP." Instantly, a visceral sensation washes over your chest and stomach. * *Common Mismapping*: People often confuse *Feeling* (*vedanā*) with complex thoughts or psychological narratives. Canonically, *vedanā* is simply the raw, unrefined affective tone—in this case, an unpleasant feeling (*duḥkha-vedanā*). * **Ignorance (*無明*, *avidyā*) & Craving (*愛*, *tṛṣṇā*)**: Unaware of how this physical-mental sensation arose from conditional factors (the phone battery, light rays, visual receptors, neurochemicals), an immediate reactive impulse triggers. You feel a desperate urge to eliminate the unpleasant feeling. This is *Craving*—the instinctual thirst to push away discomfort or grasp for security.

2. Overtime, Social Media Scrolling, and the Delusion of Self

* **Clinging (*取*, *upādāna*) & Becoming (*有*, *bhava*)**: Late at night after working overtime, you sit on the couch scrolling through social media feeds. You see posts of friends vacationing or celebrating achievements. * *Clinging* occurs as your mind grabs onto specific narrative concepts: *"I am falling behind," "My work is unappreciated,"* or *"I need a different life."* * *Becoming* (*bhava*) is the psychological momentum generated by this grasping—the mental posture of an anxious, defensive, or envious "I" preparing to react. * The Tree and Shadow in Action: Your feeling of envy or inadequacy seems like a solid, permanent trait of your personality (*"I am an anxious person"*). But in reality, it is purely a *緣生法*—a dependently arisen phenomenon. The external post (*object*), your tired eyes (*organ*), your fatigue (*condition*), and unexamined stories (*ignorance*) converged to produce the feeling. Just as a shadow disappears when the tree's roots are cut, the moment you put the phone down, take three deep breaths, and let the neurochemical cascade dissipate, the feeling of envy vanishes. It possessed zero inherent existence (*svabhāva*).

3. Intimacy and Relationships

* Misinterpreting the Partner: In a domestic disagreement, your partner speaks in a sharp tone. * The Chain of Conditions: The sharp tone is an auditory object; your ear organ receives the sound waves; auditory consciousness registers it; contact occurs. Instantly, past conditioning (memories of past arguments, underlying insecurities—*volitional formations/saṃskāra*) shapes the sensation into a hostile perception. * Where We Map It Wrong: We usually assume: *"My partner made me angry; my anger is a real thing inside me, and my partner's hostility is a fixed trait."* * The Correction via Dependent Arising: A practitioner observing *緣生* sees that neither the partner's words nor one's own anger exists as an isolated, independent entity. The anger is a temporary assemblage of past memories, current physical exhaustion, sound waves, and unmindful reflection (*不正思惟*). Seeing that all these elements are dependently arisen and lack a fixed owner (*"摩納婆"*, a substantial individual self), the compulsion to retaliate melts away.

4. Parenting and Expectations

* The Illusion of Control: You want your child to perform well academically or behaviorally. When they struggle, intense grief or frustration arises. * Tracing the Causes: The child's behavior is itself a dependently arisen phenomenon—influenced by their genetics, peer environment, fatigue, diet, and emotional maturity. Your reaction is likewise dependently arisen—built on social expectations, parental pride, and fear of the future. * Liberation in the Moment: Realizing that the situation is *"因緣和合生,緣離則磨滅"* (arising from the gathering of conditions, dissolving when conditions shift), you stop viewing the child or yourself through rigid labels. You focus on adjusting the actual *conditions* (providing rest, changing communication tone) rather than fighting an imaginary, fixed "problem."


Why Modern People Need It

In contemporary life, we are perpetually trapped in an illusion of hyper-individual agency and rigid existential isolation. Modern culture tells us that everything is an isolated object: *my* career, *my* brand, *my* trauma, *my* success. This framework turns life into an exhausting battle between self and world. *緣生* offers a profound liberation from this exhaustion.

1. Deconstructing Psychological Reification

Modern individuals frequently suffer from psychological reification—treating dynamic, temporary mental states as permanent identity markers. Phrases like *"I am a stressed person,"* *"I am inherently anxious,"* or *"My depression defines me"* reflect a subtle belief in an unchanging self-entity.

When understood through *緣生*, feelings, thoughts, and emotional crises are recognized as conditioned, impermanent events (*緣生法*). They are like weather patterns resulting from atmospheric pressure, humidity, and temperature. When you realize an emotion is dependently arisen, you stop taking it personally. You do not need to fight or identify with the storm; you simply observe the conditions shifting and dissolving (*緣散即滅*).

2. AI, Algorithms, and the Modern Condition

Today's algorithmic environments (social media feeds, recommendation systems, generative AI) are engineered to exploit the lower links of Dependent Origination—specifically targeting Contact (*sparśa*), Feeling (*vedanā*), and Craving (*tṛṣṇā*).

* How Algorithms Leverage Conditions: An algorithm feeds you content calculated to generate a quick ping of pleasure or outrage (*unpleasant/pleasant feeling*). Without mindfulness, this instantly triggers *Craving* (wanting to keep scrolling or wanting to comment) and *Clinging* (identifying with a polarized viewpoint). * The Insight of Dependent Arising: Understanding *緣生* provides an internal firewall. You recognize that your sudden urge to buy something or your sudden surge of outrage is not "yours" in a vacuum; it is a predictable output generated by specific external inputs (data models, blue light) interacting with internal conditioning. By recognizing the chain of conditions, you cut the link between *Feeling* and *Craving*.

3. Dialogue with Contemporary Science and Its Limitations

Modern science—particularly neuroscience and complex systems theory—echoes aspects of *緣生*: * Neuroscience: Brain science shows that a single emotion or decision is not made by a centralized "homunculus" or soul in the brain. Instead, it emerges from billions of neurons firing together based on sensory inputs, historical neural pathways, and blood chemistry. This strongly aligns with the Buddhist rejection of an isolated self (*anatman* / no *摩納婆*). * Systems Theory: Ecology and physics demonstrate that no event occurs in isolation; every system is an interconnected web of feedback loops.

Crucial Distinction & Scientific Limitations: While neuroscience and systems theory describe physical and biological dependencies, they operate almost exclusively within empirical measurement and physical causation (*sṃvṛti-satya*, conventional truth). They often fall into physical reductionism (claiming mind is *nothing more than* physical brain matter).

In contrast, the Buddhist teaching of *緣生* spans both conventional truth (*俗諦因緣處*) and ultimate truth (*paramārtha-satya*): * It does not reduce mind to matter; rather, it reveals that both physical form (*rūpa*) and mental processes (*nāma*) arise interdependently (*名色*). * More importantly, science describes phenomena to control or predict them, whereas the Buddha taught *緣生* for a singular, existential purpose: **the complete cessation of suffering (*寂靜*, *涅槃*)**. Science maps the cage; *緣生* shows how to step out of the cage entirely by dismantling ignorance (*avidyā*).


Common Misunderstandings and Clarifications

Because *緣生* is a radical and subtle teaching, it is frequently misunderstood by modern seekers. Below are the most critical misinterpretations cleared through classical canonical definitions:

Misunderstanding 1: "Dependent Arising means Fatalism or Determinism"

* The Misconception: *"If everything arises due to prior causes and conditions, then my life is entirely predetermined by my past karma, environment, or genetics. I have no real choices."* * Canonical Clarification: *緣生* is not fatalistic determinism (*hetu-patrikyā-vāda*). In the *Samyukta Āgama*, the Buddha explicitly rejected the view that everything experienced in the present is strictly caused by past action. Dependent origination is a dynamic, multi-directional network. Present conditions—specifically wise attention (*yoniśo manasikāra*, 正思惟) vs. unwise attention (*ayoniśo manasikāra*, 不正思惟)—actively shape the current moment. While past conditions set the stage, your present moment mindfulness determines whether the chain continues from *Feeling* into *Craving* and *Suffering*, or breaks into *Cessation* (*因緣滅故,即是寂靜*).

Misunderstanding 2: "Dependent Arising means Nothing Exists (Nihilism)"

* The Misconception: *"If things rely on conditions and are empty of self-nature, then nothing actually exists, moral choices don't matter, and everything is just an illusion."* * Canonical Clarification: In the *Māhāratnakūṭa Sūtra*, the Buddha carefully distinguishes between conventional reality (*俗諦因緣處* / *因緣世諦*) and ultimate emptiness. *緣生* rejects two extreme views: 1. Eternalism (*śāśvata-dṛṣṭi*): Believing things have an unchanging, independent essence or soul. 2. Nihilism (*uccheda-dṛṣṭi*): Believing that things do not function or that cause and effect do not operate. Dependently arisen phenomena are not non-existent; they exist conventionally as conditioned processes. Karma, choices, and compassion function perfectly within the realm of causes and conditions. It is precisely *because* things are dependently arisen (and not fixed) that transformation, learning, and liberation are possible.

Misunderstanding 3: "Equating 'Dependent Arising' (*pratītyasamutpāda*) with 'Dependently Arisen Phenomena' (*pratītyasamutpanna*)"

* The Misconception: Treating the rule of causality and the objects produced by causality as the exact same thing. * Canonical Clarification: As emphasized in the *Samyukta Āgama*: * 因緣法 / 緣起 (*pratītyasamutpāda*): The immutable, objective *law* of conditionality itself (*法常住,法住法界*)—the structural reality that when conditions gather, effects arise. * 緣生法 (*pratītyasamutpanna*): The actual, impermanent, conditioned *results*—such as the five aggregates, aging, pain, or temporary joy—that manifest in accordance with that law.

Misunderstanding 4: "Mistaking 'Unarisen' (*無生*) for Emotional Numbness"

* The Misconception: In Mahāyāna texts like the *Mahāsaṃnipāta Sūtra*, it states that *"缘生即無生"* (dependent arising is unarisen). Modern readers sometimes interpret this as a call to suppress feelings, ignore relationships, or cultivate cold detachment. * Canonical Clarification: "Unarisen" (*anutpāda*) does not mean suppressing feelings or pretending life isn't happening. It describes a profound cognitive insight: when you look deeply into any arising emotion, thought, or event, you discover it has no fixed, independent core that ever truly "came into solid existence" on its own. Understanding that phenomena are inherently unarisen frees you from grasping (*不執緣生法*) and allows you to move through life with immense flexibility, warmth, and unhindered freedom (*得自在*).

By seeing *緣生* as it truly is—a law operating right now in every breath, swipe of a screen, and emotional wave—we cease fighting reality. We stop mistaking temporary shadows for solid walls, and in doing so, we step onto the direct path to peace.

Canonical EntryAI-generated

一、定义与核心要义

「緣生」(pratītyasamutpanna)是佛陀阐释宇宙万有生灭变化的核心概念。在《雜阿含經》中,佛陀对「緣生法」给出了明确的定义,指出其具体涵盖了无明、行、识、名色、六入处、触、受、爱、取、有、生、老、病、死、忧、悲、恼、苦等十二支。其核心运作机制表现为「緣無明有行,乃至緣生有老死」,即因为种种因缘的生起,而导致老、病、死等诸苦的聚集。这一缘生规律具有客观的常住性,无论佛陀是否出世,「此法常住,法住法界」,展现出「法住、法空、法如、法爾,法不離如,法不異如,審諦真實、不顛倒」的特質。

在《大寶積經》与《大方等大集經》中,缘生的定义被进一步深化为「缘生即无生」的实相。诸法并非真实存在,而是「因緣和合起」的产物。经中指出,若说诸法从缘而生,则此「生」既非「生已生」,亦非「未生生」,因此其体性本质上是「無生」与「無自性」的。

二、主要阐述

各经从无常、无自性、苦轮流转以及修行实践等多个维度,对缘生法进行了系统而深刻的阐述:

1. 缘会而生与无常消灭: 《雜阿含經》强调缘生法具有「緣會而生,緣散即滅」的特征。比丘尼们在修行中观察到:「彼彼法緣生彼彼法;彼彼緣法滅,彼彼生法亦復隨滅」。经中以大树与树影为喻,说明若无常的树根、茎、叶不复存在,其所依的树影也随之消失;同理,若外六入处是无常的,则依其所生的喜乐也绝非恒常。偈颂中亦以「此形」(身体)及「陰界入」为例,指出它们是「因緣和合生,緣離則磨滅」,如同种子依大地、水、火、风而生长。

2. 因缘和合与无自性空: 《大寶積經》从世俗谛角度论述了因缘和合的虚幻性。以「觸」为例,指出「觸但有名字,其性不可得」,若能了知其因缘和合、毕竟无所有的本质,即是证入「觸三昧」。经中强调「一切法無入,但說緣和合」,佛陀正是悉知诸法「從緣起」,才宣说它们「無自性」。而在《大方等大集經》中,则通过剖析因与缘之间并无自体实性(「緣中有因耶?無也。因中有緣耶?無也」),论证了「一切法自性無生」的实相。

3. 苦轮的运转与断绝: 缘生机制直接关联到生死的流转与解脱。在《大寶積經》中,这一规律被概括为「眾緣有故苦綸運,眾緣無故苦綸斷」,说明苦的运转与断绝完全取决于众缘的具足与否。而在《大方等大集經》中,马星比丘亦将释迦牟尼佛的教法核心概括为:「法從緣生,通達是因,因緣滅故,即是寂靜」。

4. 修行实践与证悟意义: 对缘生法的如实正知具有重要的修行价值。在《雜阿含經》中,多闻圣弟子若能对因缘法与缘生法正知善见,便能断除对过去世与未来世的疑惑,并彻底断除「我見」、「眾生見」、「壽命見」等凡俗系缚。在《大方等大集經》中,「修緣生法得」是菩萨成就「陀羅尼行」且终不失念的重要基石。在《大寶積經》中,菩萨摩诃萨通过在「緣生法」中了解一切身,得以引摄并证得法身,进而示现蕴界处身以调伏众生。

三、不同部类与译本的表述差异

在不同部类的经典及译本中,对于「缘生」及相关概念的译词和表述存在明显的差异:

1. 核心术语的表述: * 《雜阿含經》主要使用「緣生法」与「因緣法」。 * 《大寶積經》(唐菩提流志译)除了使用「緣生」、「緣生法」外,还频繁使用「從緣生」、「從緣起」、「因緣和合起」及「緣和合」等。在描述世俗因果时,该经使用了「俗諦因緣處」、「因緣世諦」、「因緣所作事」等独特术语。 * 《大方等大集經》(北涼昙无谶译)则多表述为「從緣生」或「緣生法」。

2. 名相合称与人称代词: * 《雜阿含經》使用「陰界入」这一合称来指代五阴、十八界与十二入;并以「外六入處」指代外部的感官对象。 * 《大寶積經》在否定自我实体时,使用了音译词「摩納婆」来指代人或有情。

3. 人名翻译的独特特征: * 《大方等大集經》在叙述缘起偈的历史背景时,采用了独特的译名:将舍利弗(Śāriputra)译为「優波提舍」,目犍连(Maudgalyāyana)译为「拘律陀」,阿说示(Aśvajit)译为「馬星」。

四、与相关概念的关系

1. 与「无生/无自性」的关系: 缘生与无生在深层义理上是统一的。《大寶積經》中无畏女阐明「一切諸法體性不生」;菩萨若能「順行緣生」即被称为「不生」,若能「不執緣生法」则被称为「得自在」。《大方等大集經》亦指出,正因为是缘生,所以「一切法無自性,無生無起無出」,自性与他性皆不能互相生起。

2. 与「四圣谛」的关系: 《大方等大集經》将缘生法直接与四圣谛相结合,指出「世間即苦,苦因名集,若修八正,世間集滅。若無苦集……名為涅槃」。通达缘生之因并使其消灭,即是寂静涅槃。

3. 与「消灭/寂灭」的关系: 在描述因缘消散的寂灭状态时,《雜阿含經》频繁使用「隨滅、息、沒、寂靜、清涼、真實」等独特的连缀术语,说明因缘离散即能导向寂灭。

五、代表性原文引用

1. 《雜阿含經》:「彼彼法緣生彼彼法;彼彼緣法滅,彼彼生法亦復隨滅、息、沒、寂靜、清涼、真實。」 2. 《雜阿含經》:「因緣和合生,緣離則磨滅。」 3. 《大寶積經》:「若以緣生,彼無生義……一切諸法體性不生。」 4. 《大寶積經》:「眾緣有故苦綸運,眾緣無故苦綸斷。」 5. 《大方等大集經》:「若能如實解了緣生法者,名為佛出世。」 6. 《大方等大集經》:「法從緣生,通達是因,因緣滅故,即是寂靜。」

入中論善顯密意疏B0044 · 藏傳論典部

《入中論善顯密意疏》以「依因待緣而生」說明諸法之生起。頌文先以有情執著為例:最初執「我」,繼而執著「我所」之法,遂如水車流轉而不得自在;正因見其緣生流轉,乃興起悲心。此處「緣生」不僅描述諸法的成立方式,也與觀察有情之苦及生悲相連。

本論對緣生的核心判定,是排除無因及各種自性成立的生法:諸法並非無因自然生,亦非由自在天、時、微塵、自性、士夫、那羅延天等為因而生;又非自生、他生或共生,故說「唯是依緣生」。其正面意義是:依於此因緣,乃有彼果生;破除四生,並不等於全無生,也不破壞世間因果名言。

本論以「此有故彼有,此生故彼生」表述緣起的觀待關係,並以「無明緣行」為例;作者、業等亦依彼此而立,除此緣起之外,更無另外成立業果及作者的成因。因此,本論明確區分「非四邊生」與「全無生」:雖不承認自、他、共、無因等生,仍總許名言中的生,稱為「緣起生」或「觀待緣起」。

緣生又被用來揭示空性。本論說,若主張自相成立而又依緣生,並認為否定自相便會毀壞諸法,則空性反成壞法之因;此理不成,故諸法無性。換言之,緣起的深義即空性義:由諸法依緣生,便非分別所能以自性方式觀察,故以緣起之理能破除增益自性的常見、全無作用的斷見等「惡見網」。

本論亦以三界說明緣生與性空的同一指向:三界從緣而生,故名「有為」;三界即由其自性空,故名「有為空」。又說諸法從緣生,並無自性成立的「和合性」;和合由彼空,稱為「無性空」。因此,從緣而生並非另有實在自性,而正用以說明有為法與和合法之自性空。

在譬喻方面,本論以日輪影像說明:影像中雖可見日蝕等差別,日與影究竟相合或不合皆不合理,然而影像仍可於名言中依緣生起;又如鏡影雖不實,仍能用於修飾面容。藉此指出,因雖非實有,仍能在名言中發生作用,不因無自性而失去效用。

就術語而言,《入中論善顯密意疏》主要使用「緣生」,並有「依緣生」「從緣生」「名言依緣生」「緣起」「緣起生」「觀待緣起」及「唯有緣性之緣起」等形式;論述佛智所現境時,又用「所現唯緣生」。這些詞在本論中共同指向依待因緣而有、於名言成立而無自性的諸法,並非以某一實有本體作為生因。

雜阿含經T0099 · 阿含部

本經(《雜阿含經》此兩段)對「緣生」的論述,分為兩側面,分述如下。

一、正面定義:「因緣法」與「緣生法」之分別與內容

世尊於王舍城迦蘭陀竹園,明確區分兩個相關概念而說:「我今當說因緣法及緣生法」。所謂「因緣法」,即「此有故彼有」,其內容為「緣無明行,緣行識,乃至如是如是純大苦聚集」——指出十二支緣起的推動原則。所謂「緣生法」,即「無明、行、識、名色、六入處、觸、受、愛、取、有、生、老、病、死、憂、悲、惱、苦,是名緣生法」——指出十二支本身即屬依緣所生之諸法。

經文特別強調,此「緣生法」自有常住的法性:「若佛出世,若未出世,此法常住,法住法界」,並以多重法相形容之:「法住、法空、法如、法爾,法不離如,法不異如,審諦真實、不顛倒」——此即為本經論「緣生」時最獨特的法相術語。換言之,緣生諸法之「如」與「法住」,並非佛所新造,而是如來所自覺知而為人「演說、開示顯發」者。

二、實修觀察的運用:法句重述與譬喻引入

另有一段(難陀尊者與諸比丘尼之問答)中,將緣生之理應用於實修觀察。其核心法句為:「彼彼法緣生彼彼法,彼彼法緣滅,彼彼生法亦復隨滅、息、沒、寂靜、清涼、真實」。此句由比丘尼自答而出,難陀隨即予以讚嘆並囑咐「汝於此義應如是觀察」、「汝於此義當如實觀察」,可知此觀察法為正修所依。本經此處以「彼彼法」一語反覆標舉緣生、緣滅相應之理,與前段十二支之正面列出,術語形式不同而義理相通。

為令此義具解,本段舉二譬:(一)大樹之喻——「譬如大樹根、莖、枝、葉,根亦無常,莖、枝、葉皆悉無常」,樹既無常,依樹而立之影亦無常可得;由此明若說「外六入處因緣生喜樂」為「常、恒、住、不變易、安隱」者,「非為等說」。(二)屠牛剝皮之喻——「譬如善屠牛師、屠牛弟子手執利刀,解剝其牛,乘間而剝,不傷內肉、不傷外皮,解其枝節筋骨」;皮肉看似相連,實已分離,以顯依緣生起之諸法,滅時並非保留其體不變。

三、修證之果

「緣生」之觀察果相為「息、沒、清涼、真實」;而於正式定義的段落中,多聞聖弟子「於因緣法、緣生法正知善見」,不起前後際之見,「若沙門、婆羅門起凡俗見所繫……爾時悉斷、悉知,斷其根本,如截多羅樹頭,於未來世,成不生法」——此即以緣生正觀斷諸見,得於未來「不生」之果。

本經以「因緣法」與「緣生法」並舉區別,為其術語特色,且為「緣生」同時確立「法住、法空、法如、法爾」之常住法性面,與「彼彼法緣生彼彼法」之觀修應用面,二面互補而同歸「審諦真實、不顛倒」之語。

大寶積經T0310 · 寶積部

此部《大寶積經》對「緣生」之論述,散見多處,核心可歸納為數端:

一、順行緣生而不執取,即名不生得自在。經文明謂:「順行緣生,是名不生;不執緣生法,名得自在」(),將隨順緣起之理趣與不執著緣生法並列為菩薩修行之要門。此處「緣生」即依因待緣而生起之諸法,而「不生」非謂斷滅,乃於緣生法上離執之智慧;得自在者,即不為緣生所縛。

二、緣生即和合而起,畢竟無所有。經以觸(sparśa)為例:「觸但有名字,其性不可得,細滑等諸法,皆是從緣生。若能知觸性,因緣和合起,畢竟無所有,是名觸三昧」(),指出緣生之法唯有假名、性不可得,了知其「因緣和合起」而當體空寂,即入三昧。

三、於緣生法了一切身,引攝法身。經云:「菩薩摩訶薩於緣生法了一切身,既了知已引攝法身」(),菩薩以如實智觀察如來身與自身平等法性,於緣生諸法究竟了達,即引攝法身、證法身,復能示現蘊界處身。此處以「緣生法」對治「法身」,顯示緣生是方便、施設之相,法身是真實、平等之性。

四、一法從緣生,眾緣有無故苦綸運斷。偈頌云:「了知一法從緣生,無摩納婆意生等,眾緣有故苦綸運,眾緣無故苦綸斷」(),明緣生與苦之生滅直接相關:眾緣具足則苦輪運轉,眾緣不具則苦輪斷絕。同偈復以聚沫喻色、浮泡喻受、陽焰喻想、芭蕉喻行、善幻喻識等,廣明緣生諸行無常無實。

五、緣生即無生之義,法界體性不生不滅。無畏女與須菩提之問答中明言:「若以緣生,彼無生義」「一切法緣生」「一切諸法體性不生」(),直接以「緣生」等同「無生」,並進一步推至法界亦「不生不滅」,以畢竟淨、離於實際為其底蘊。

術語用詞說明:此部經以「緣生」為主稱(亦見「從緣生」「因緣和合起」「緣生法」諸形),未見使用「緣起」「因緣生」「十二緣起」等其他譯名之替換形式。所論觸法、六入乃至諸行,皆置於「緣生」框架下展開。
