What Is This Concept Saying?

In the doctrinal framework of Buddhist Yogācāra (唯識學派), Non-nature of Arising (生無自性性, Sanskrit: *utpatti-niḥsvabhāvatā*) serves as a foundational pivot. According to the *Sūtra Unraveling the Intent* (*Saṃdhinirmocana Sūtra*, 《解深密經》, translated by Master Xuanzang 玄奘), when the Buddha declared the implicit teaching that "all phenomena lack inherent nature" (一切諸法皆無自性), he systematically delineated this statement into Three Non-natures (三無自性性):

1. Non-nature of Characteristics (相無自性性, *lakṣaṇa-niḥsvabhāvatā*) — corresponding to the Imagined Nature (遍計所執相, *parikalpita-lakṣaṇa*). 2. Non-nature of Arising (生無自性性, *utpatti-niḥsvabhāvatā*) — corresponding to the Other-dependent Nature (依他起相, *paratantra-lakṣaṇa*). 3. Non-nature of Ultimate Truth (勝義無自性性, *paramārtha-niḥsvabhāvatā*) — corresponding to the Consummate Nature (圓成實相, *pariniṣpanna-lakṣaṇa*), as well as partially to the Other-dependent Nature.

1. The Precise Canonical Definition

The core text of the *Saṃdhinirmocana Sūtra* provides an unequivocal definition of *utpatti-niḥsvabhāvatā*: > 「此由依他緣力故有,非自然有,是故說名生無自性性。」 > *"Because this exists through the power of other conditions, and does not exist spontaneously by itself, it is therefore named 'Non-nature of Arising.'"*

To unpack this definition without blurring its edges: * "Power of other conditions" (依他緣力): Any phenomenon that comes into being does so exclusively because a cluster of causes and supporting conditions (*pratyaya*) assemble. * "Not existing spontaneously" (非自然有): It lacks a causeless, self-generated, independent, or unalterable core essence (*svabhāva*). * The "Arising" (生) in Non-nature of Arising: The "arising" itself is what lacks self-nature. The process of coming into existence is entirely dependent upon causes. Because its birth relies entirely on "other" factors, its birth possesses no intrinsic, self-contained origin.

2. The Canon's Specific Metaphor: The Illusion (*māyā*, 幻像)

The Buddha used explicit, precise canonical metaphors to ground each of the three non-natures. While the *parikalpita* (imagined) nature is compared to a sky-flower (a hallucination), **the Non-nature of Arising is explicitly compared to a magical illusion (幻像, *māyā*)**.

Why a magical illusion? A illusion performatively appears before your eyes—you see the illusory horse or elephant clearly—yet its appearance depends entirely on the magician’s props, mantras, lighting, and your own perceptual faculties. The illusion does not pop into being spontaneously from its own intrinsic side. It shows up real, yet lacks an independent core. In the exact same way, all dependent phenomena (*paratantra*) display vivid appearances while remaining thoroughly unanchored by any self-subsistent reality.

3. Corresponding Nature and Universal Scope

*Utpatti-niḥsvabhāvatā* is established directly upon the Other-dependent Nature (依他起相, *paratantra-lakṣaṇa*). The text defines *paratantra-lakṣaṇa* as "the mental representations relied upon when conceptual discrimination engages in imagined attachments" (分別所行遍計所執相所依行相).

This is not restricted to material objects. The *Saṃdhinirmocana Sūtra* explicitly spans the full spectrum of reality across the following categories: * The Five Aggregates (五蘊): Form (色), Feeling (受), Perception (想), Volitional Formations (行), and Consciousness (識). * The Twelve Sense Bases (十二處) and Eighteen Realms (十八界): All sensory organs, their external objects, and the corresponding conscious awareness. * The Twelve Links of Dependent Origination (十二有支): From Ignorance (無明) down to Aging and Death (老死). * The Four Sustenances (四種食): Nutritive food, sensory contact, mental volition, and consciousness. * The Four Noble Truths (四聖諦): Including Suffering (苦諦) and Origin (集諦). * Practices and Paths to Liberation: The Thirty-Seven Factors of Awakening (三十七道品, including Mindfulness, Right Effort, Spiritual Powers, Faculties, Powers, Awakening Factors, and Path Factors) and states of meditative concentration (正定).

Whether it is worldly defiled phenomena (雜染法) or transcendent pure paths of practice (清淨法), as long as it arises through causes and conditions, it falls under the purview of *utpatti-niḥsvabhāvatā*.

4. Spiritual Pedagogy: The Three Stages of Guidance

In the *Saṃdhinirmocana Sūtra*, *utpatti-niḥsvabhāvatā* is not merely an abstract philosophical taxonomy; it functions as a critical pedagogical stepping stone in the Buddha's gradual path:

1. Initial Stage (Cultivating Disenchantment): For beginners who have not yet planted wholesome roots, purified karmic obstacles, or gathered adequate stores of merit and wisdom, the Buddha expounds teachings *based on the Non-nature of Arising*. Hearing that all conditionings are conditionally produced, beginners recognize that conditioned things are "impermanent, non-constant, unstable, and subject to decay" (無常、無恒,是不安隱變壞法). This sparks a healthy sense of spiritual dread and disillusionment (深起厭患), driving them to abandon misdeeds and diligently cultivate wholesome momentum. 2. Intermediate Stage (Recognizing the Limit): While this disenchantment establishes wholesome roots, the practitioner at this stage has "not yet truly comprehended the Non-nature of Characteristics and the two types of Non-nature of Ultimate Truth." Relying solely on impermanence and conditioned decay can lead to revulsion, but not complete freedom. 3. Ultimate Liberation (Transcending Attachment): To complete the path, the Buddha unveils *lakṣaṇa-niḥsvabhāvatā* and *paramārtha-niḥsvabhāvatā*. By integrating these, the practitioner realizes that while conditions assemble (the *paratantra* aspect), the projecting mind's reified mental constructs (the *parikalpita* aspect) were never real to begin with. By dropping reification right within the conditionally arisen reality, they cut off future seeds and achieve total liberation from the Three Defilements: Afflicting Defilement (煩惱雜染), Karmic Defilement (業雜染), and Rebirth Defilement (生雜染).


A Walkthrough in Daily Life

To understand *utpatti-niḥsvabhāvatā*, we must trace how our everyday experience operates through the Lens of Dependent Arising vs. Intrinsic Illusion.

Scenario 1: The Late-Night Work Email & Physical Anxiety

Imagine you are relaxing at 10:00 PM. A notification dings: an urgent email from your manager criticizing a project presentation. Immediately, your chest tightens, your heart rate spikes, and a knot forms in your stomach.

* Where people map it wrong: We tend to treat the "anxiety" or "the toxic boss" as solid, self-existing entities. You think: "I am an anxious person" or "My job is fundamentally a nightmare." * **Mapping via *Utpatti-niḥsvabhāvatā*:** * Form Aggregate (色蘊): Light waves hitting the retina from the blue-light screen; adrenaline secreted by the adrenal glands. * Sensory Base & Realm (處/界): The visual organ contacting the text characters, triggering mental consciousness (意識). * Feeling Aggregate (受蘊): Unpleasant visceral sensation (苦受). * Perception Aggregate (想蘊): Identifying the letters as words denoting "threat" and "failure." * Volitional Formations (行蘊): The mental urge to draft a defensive reply or catastrophize. * The Arising: The physical panicky sensation did not exist 5 seconds prior. It did not jump out of thin air ("spontaneously"). It arose exclusively due to a precise convergence: eye organ + screen light + past memory conditioning + physiological fatigue + language processing. * The Realization: Because its arising is entirely dependent on these "other" factors (*paratantra*), the panic has no intrinsic self-nature (*utpatti-niḥsvabhāvatā*). It is an "illusion" (幻像)—vividly felt, yet unanchored by any solid, unchangeable essence. When you close the phone, stretch, and alter the physical conditions, the physiological state shifts.

Scenario 2: Social Media Doomscrolling & Relationship Jealousy

You are scrolling through an algorithmically curated feed and see a friend posting photos of their new luxury home or romantic getaway. A wave of bitterness, envy, and inadequacy washes over you.

* Where people map it wrong: You reify the feeling into an absolute self-identity: "My life is a failure, and they have an inherently perfect existence." * **Mapping via *Utpatti-niḥsvabhāvatā*:** * Sustenance (食): Sensory contact (*sparsa-āhāra*, 觸食) with the screen and mental intent (*manosañcetanā-āhāra*, 意思食). * Imagined Attachment (遍計所執): Projecting a static, flawless narrative onto a 2-D image. * Other-dependent Arising (依他起): The envy is a temporary mental formation (*caitta*) arising from sensory stimulus + underlying comparison patterns + current state of exhaustion. * The Realization: The envy is not "you," nor is it a permanent feature of reality. It arose through specific conditions (the algorithm, fatigue, conceptual habits). It possesses no "self-arising nature." Recognized as a magician's trick, the emotion loses its authority to dictate your self-worth.


Why Contemporary People Need It

Modern culture is locked in an interplay between two extremes: rigid essentialism ("I am hardwired this way by my genetics/trauma") and hyper-individualistic voluntarism ("You can manifest anything if you just fix your mindset"). *Utpatti-niḥsvabhāvatā* offers a profound middle path grounded in deep wisdom.

1. From Weariness to Freedom: Moving Beyond the First Stage

Many modern self-help systems or early meditation practices stop at the early stage of recognizing impermanence: "Everything changes, life is stressful, burnout is inevitable." This often leads to cynical exhaustion or stoic detachment—what the *Saṃdhinirmocana Sūtra* calls "disenchantment" (厭患).

While disenchantment stops us from recklessly chasing illusions, staying there leads to spiritual paralysis. *Utpatti-niḥsvabhāvatā* reminds us that conditionality works both ways: Because things do not possess a fixed, self-originating nature, they are workable. A stressful mind state is not a concrete monument; it is a dynamic process built of conditional inputs. If you adjust the conditions (sensory input, cognitive framing, physical rest), the outcome must change.

2. Dialogue with AI, Neuroscience, and Algorithms

Contemporary neuroscience demonstrates that what we call "consciousness" or "emotion" is a constructed predictive state generated by neural networks reacting to internal bio-signals and external stimuli. Similarly, AI models generate complex outputs based on contextual prompts and training weightings—outputs that appear spontaneous but are entirely dependent on underlying parameters.

* The Scientific Parallel: Modern cognitive science agrees that mental states do not arise out of a central, uncaused "soul-homunculus." They are dependent emergent phenomena. * The Buddhist Distinction: Neuroscience often risks falling into physicalist reductionism ("you are just a bag of neurons"), which can lead to nihilism. *Utpatti-niḥsvabhāvatā* does not negate experience or reduce mind to mere dead matter; it points out that the *arising process itself* lacks intrinsic selfhood so that the mind can untangle its reified projections (*parikalpita*) and realize ultimate peace (*pariniṣpanna*).


Common Misunderstandings and Clarifications

To master this concept, one must avoid several frequent misinterpretations:

1. "Non-nature of Arising" means things don't actually arise or exist at all (Nihilism / 惡取空)

* Clarification: *Utpatti-niḥsvabhāvatā* does not say that phenomena do not appear. The *Saṃdhinirmocana Sūtra* uses the metaphor of an illusion (幻像): when a magician creates an illusory horse, the visual appearance *is definitely there*. You see it. What is *absent* is a real, independent, non-dependent horse inside the illusion. Similarly, feelings, thoughts, and physical objects *do arise conditionally* (依他起); what they lack is a spontaneous, self-contained, uncaused nature (非自然有).

2. Confusing Conditionality with Fatalistic Determinism

* Clarification: One might think, "If everything depends on conditions, I am just a helpless puppet of past causes." In Yogācāra, volition (思, *cetanā*) and mental cultivation are themselves powerful conditions within the dependent network. Recognizing that arising depends on conditions empowers you to introduce *new* wholesome conditions (such as mindfulness, ethical restraint, and wisdom), thereby transforming the trajectory of dependent origination.

3. Conflating *Utpatti-niḥsvabhāvatā* with *Lakṣaṇa-niḥsvabhāvatā*

* Clarification: * Non-nature of Characteristics (相無自性性): Refers to the Imagined Nature (*parikalpita*). It is completely non-existent, like a sky-flower or the horns of a rabbit. It is a total conceptual fiction. * Non-nature of Arising (生無自性性): Refers to the Other-dependent Nature (*paratantra*). It exists as a causal flow (like a magic trick or a shadow play), but lacks an uncaused, intrinsic essence. Failing to distinguish these leads people to treat the physical world and causal mind states as pure non-existent hallucinations, ignoring the laws of karma and conditioned reality.

4. Thinking "Non-nature of Arising" is the Ultimate Goal of Meditation

* Clarification: As the *Saṃdhinirmocana Sūtra* warns, understanding *utpatti-niḥsvabhāvatā* is an indispensable initial and intermediate step. It helps us see the impermanence and instability of conditioned things. But true, ultimate liberation requires advancing to Non-nature of Ultimate Truth (勝義無自性性)—where, right within this conditionally arisen world, all conceptual reifications are thoroughly extinguished, revealing the tranquil, unconditioned reality of Suchness (眞如, *tathatā*).

Canonical EntryAI-generated

一、 定义与核心要义

在佛教唯识学派的理论体系中,「生无自性性」(梵语:utpatti-nihsvabhāvatā)是一个极为核心的范畴。根据唐代玄奘大师所译的《解深密经》(《解深密經》),佛陀在宣说「一切诸法皆无自性」这一密意时,将其细分为三种无自性性,而「生无自性性」即是其中不可或缺的关键组成部分。

「生无自性性」的核心定义在经中被明确表述为:「此由依他缘力故有,非自然有,是故说名生无自性性。」 这意味着,世间一切被认为是存在的事物(诸法),其产生与存在完全是依凭、仰赖其他因缘的力量而得以成立,并非是自发、自然、独立地拥有一个不变的「自性」。为了让有情众生更好地理解这一抽象的法理,佛陀在经中采用了极具直观性的比喻,将「生无自性性」的特征比喻为「幻像」。幻像虽有显现,但其本身并无真实独立的实体,完全依赖幻术师等外在因缘而起,这正契合了生无自性性的本质。

二、 主要阐述

1. 依他起相的本质与施设基础 在《解深密经》的论述中,「生无自性性」与「依他起相」具有直接且密不可分的对应关系。经中指出,所谓的「依他起相」,其本质就是「分别所行遍计所执相所依行相」。也就是说,众生在进行分别、执着时,其所依凭的种种行相,即是依他起相。佛陀正是依据这种「分别所行遍计所执相所依行相」,在教法中施设了「生无自性性」以及「一分胜义无自性性」。

2. 广泛的适用范畴 「生无自性性」的施设并非仅仅适用于部分现象,而是遍及于一切法、一切佛教核心名相与修行法门之中。具体而言,经中列举了以下范畴: - 诸蕴:如「色蕴」等五蕴; - 诸处:即「十二处」; - 诸界:包括「六界」与「十八界」; - 因缘流转:即「十二有支」; - 维持生命的资具:即「四种食」; - 诸谛:如「苦谛」等四圣谛; - 修行法门:包括「念住、正断、神足、根、力、觉支、道支」等三十七道品,以及「正定」等禅修法门。 这表明,无论是世间的杂染流转法,还是出世间的清净修行法,只要是属于依他起、因缘所生的范畴,皆属于「生无自性性」所涵盖的范围。

3. 独特的修行与度化阶位(功能) 在《解深密经》中,「生无自性性」不仅是一个理论概念,更在佛陀度化众生的实践步骤中扮演着层次分明的引导角色: - 初阶引导:对于那些尚未种植善根、未能清净业障、也未积集足够福德智慧资粮的初级有情众生,佛陀特意「依生无自性性宣说诸法」。当这些有情听闻此教法后,便能于一切缘生行中,如实了知其具有「无常、无恒,是不安隐变坏法」的特征。由此,他们会在内心深处对生死流转产生怖畏,并「深起厌患」。在这种厌离心的驱使下,有情得以遮止种种恶行,勤奋修持一切善法,从而逐步积集起解脱所需的资粮。 - 进阶超越:虽然有情通过上述修行种植了善根,但此时他们在「生无自性性」的教法中,还「未能如实了知相无自性性及二种胜义无自性性」。这意味着,仅仅停留在对因缘生灭、无常变坏的认识上,还不足以达到究竟的解脱。 - 究竟解脱:为了引导众生走向究竟,如来进一步为其宣说「相无自性性」与「胜义无自性性」。有情若能在已有的「生无自性性」基础上,正信解、通达这两种更为深细的无自性性,便能够在「依他起自性」中,不再执著于「遍计所执自性相」。通过这种智慧的现前,修行者得以永断当来世的因,从而彻底解脱烦恼杂染、业杂染、生杂染等三种杂染,获得究竟的涅槃。

三、 不同部类与译本的表述差异

在探讨「生无自性性」的文献呈现时,必须注意其在特定译本中的术语特征。以唐代玄奘大师所译的《解深密经》(《解深密經》)为例,该译本在论述此概念时,展现了高度系统化与规范化的唯识学术语体系: 1. 三性与三无性的严密对应:本经在阐释生无自性性时,始终将其置于「依他起相」(或「依他起自性」)、「遍计所执相」(或「遍计所执自性」)与「圆成实相」(或「圆成实自性」)的三性框架内进行对比与界定。 2. 译语的标准化:在具体名相的翻译上,玄奘译本具有鲜明的时代特征。例如,在指代物质与精神的聚合时,本经一律使用新译的「蕴」(如「色蕴」、「诸蕴」),而非早期译本中常见的「阴」(如「五阴」);在指代感官与对象的联系时,使用「处」(「十二处」);在指代世界的构成要素时,使用「界」(「六界、十八界」);在指代因缘连锁时,使用「有支」(「十二有支」)。这些标准化的术语,为精确理解「生无自性性」的哲学内涵提供了规范的语言载体。

四、 与相关概念的关系

1. 与「依他起相」的关系 「生无自性性」是直接依据「依他起相」而施设的。依他起相代表了事物依因缘而生的现象事实,而生无自性性则是对这一事实之本质(即无自然有的自性)的理性审视与定性。 2. 与「胜义无自性性」的关系 两者之间存在着多重的交织关系。首先,依他起相因为具有「生无自性性」的缘故,在某种意义上亦被称为无自性性。其次,由于依他起相「非是清净所缘境界」,它在唯识体系中也被施设为「一分胜义无自性性」。这表明生无自性性与胜义无自性性在依他起相上产生了交汇。 3. 与「相无自性性」及「胜义无自性性」的修行关联 在修行的进阶路径中,生无自性性是认识的起点。修行者首先通过生无自性性认识到缘生法的无常与不安隐,但必须进一步通达「相无自性性」与「胜义无自性性」,才能在依他起自性中断除对遍计所执自性的执着,最终实现三杂染的解脱。

五、 代表性原文引用

1. 关于生无自性性的核心定义: 「此由依他缘力故有,非自然有,是故说名生无自性性。」 2. 关于依他起相作为施设基础的原文: 「分别所行遍计所执相所依行相」即是「依他起相」,佛陀即是依此行相施设「生无自性性」与「一分胜义无自性性」。 3. 关于初阶引导中众生听闻后的心理转变: 有情听闻依生无自性性宣说之诸法后,「于一切缘生行中」,了知其「无常、无恒,是不安隐变坏法」,从而「深起厌患」。

入中論善顯密意疏B0044 · 藏傳論典部

本疏以「自性生」一詞為主軸,層層闡發「生無自性性」之義理。以下依疏文脈絡歸納數端:

一、緣生即無自性生。疏云:「若依彼彼生,即自性不生,自性不生者,云何得名生。」明凡依因緣而生者,即無自性之生起;又引龍猛菩薩「因緣所生法,我說即是空」及經「若從緣生即不生,此中無有生自性。若法依緣即說空,知空即是不放逸」之文,顯「緣生」與「無自性生」二名同指一事。

二、引《楞伽經》為佛自釋密意。疏云:「顯句論引楞伽經云:『大慧,我依自性不生密意,說一切法不生。』佛自解其密意故。」明示世尊宣說一切法不生之密意,即在「自性不生」。

三、以破四邊生成立無自性生。疏云:「若能破四邊生,則亦成立破自性生。故彼量式,無不成立無自性生之過……下文亦以破四邊生為因,說諸法離自性生。」即破自生、他生、共生、無因生,同時即成立遮遣自性生。

四、明「無自性」為純遮之無遮。疏云:「決擇無自性時之所立,即唯遮所破之無遮。」引《顯句論》「無事即無自性義」;又云「若謂亦非無自性者,則應成有自性,離此更無第三品故」,以遮性顯其唯遮而非別立。

五、辨自他生等邪執唯由自性見生。疏云:「唯計有自性者,乃有自然生,自生,他生,自在等生,及生已安住不滅之常,與壞已斷滅等分別。餘則不爾。」

六、以夢喻顯諸法無自性生。疏引經云:「猶如所見幻有情……一切法如同幻事亦如夢」「三有眾生皆如夢,此中不生亦不死」,以夢幻喻顯一切法「非真實有」即無自性生,並謂「言不生等,當如前云:『非真實有』於所破上加簡別言」。

七、以「無我」會通「無自性」並攝於涅槃。疏云:「小乘經說一切法無我之義,即諸法無自性義。」又云:「龍猛菩薩謂經中所說之永盡,即苦蘊寂滅之滅諦涅槃,與無自性生之滅諦義同。」以無自性生之滅諦收攝小乘經中涅槃之說。

八、以依他起自性顯假有所依。疏引頌云:「是故依他起自性,是假有法所依因,無外所取而生起,實有及非戲論境。」以「依他起」明假有法之所依因,無外所取、非實有、非戲論所行。

要之,本疏以「自性生」「自性不生」「無自性生」為術語形式,以「緣生」為其同義語;以破四邊生為能立,以無遮為所立性,並會通小乘「無我」與大乘「無自性生」之義趣。

解深密經T0676 · 經集部

本經由勝義生菩薩請問、世尊開示「一切諸法皆無自性、無生、無滅、本來寂靜、自性涅槃」之密意,世尊隨即標舉「三種無自性性」——相無自性性、生無自性性、勝義無自性性——作為整部經的核心框架。

一、正解生無自性性之定義 世尊明確指出:「云何諸法生無自性性?謂諸法依他起相。何以故?此由依他緣力故有,非自然有,是故說名生無自性性。」此即以「依他起相」攝受生無自性性,其核心在於:諸法之存在乃因緣和合之力,而非自有、自成;故無有自然生起之本性,因此名為「生無自性性」。

二、本經用語之特徵 本經以「依他起相」、「依他緣力」、「非自然有」三組術語組成生無自性性之完整定義。值得注意者,本經不用「緣起」、「緣生」之簡稱,而專用「依他起」一詞標示緣生之相;又以「非自然有」一語遮破自然生起、外道自性生之計執。又以「幻像」為喻:「譬如幻像,生無自性性,當知亦爾」,以幻術所成像喻顯依他起法似有而非實有、非自然有之義。此即本經用以詮釋生無自性性之術語形式與譬喻。

三、生無自性性與其餘二種無自性性之關係 (一)勝義生菩薩領解時,將「依他起相」與生無自性性及一分勝義無自性性三者並舉繫屬:「若即分別所行遍計所執相所依行相,是名依他起相。世尊依此施設諸法生無自性性,及一分勝義無自性性。」顯示依他起相正即是生無自性性所依之行相,同時亦得分為一分勝義無自性性之所依。

(二)又依本經之施設次第:對未種善根之有情,世尊先依生無自性性宣說,使聞法者於一切緣生行中「隨分解了無常、無恒,是不安隱變壞法」,心生怖畏、深起厭患,遮止諸惡、勤修諸善;待種善根、積集福德智慧二種資糧已,更為說相無自性性及二種勝義無自性性,方能正厭、正離欲、正解脫,超過煩惱、業、生三種雜染。顯示生無自性性在整個修行道次第中居於初階引入之位。

四、所破之執 本經明示生無自性性之施設因緣:「由有情於依他起自性及圓成實自性上,增益遍計所執自性故,我立三種無自性性。」是知諸有情於依他起法上增益遍計所執自性,世尊方施設生無自性性以破其遍計所執之相。

五、了義言教之安處 勝義生菩薩以「毘濕縛藥」、「彩畫地」等喻說明:此諸法皆無自性、無生無滅、本來寂靜、自性涅槃之了義言教,遍於一切不了義經皆應安處、皆同一味,能顯發彼諸不了義經之密意。可見生無自性性之施設,非僅為一法之安立,而是整部《解深密經》用以貫攝一切不了義經之勝義言教。

瑜伽師地論T1579 · 瑜伽部

【核心表述】《瑜伽師地論》明確將「生無自性性」界定為三種無自性性之一:「一、相無自性性,二、生無自性性,三、勝義無自性性」。其核心定義為:「謂一切行眾緣所生,緣力故有,非自然有,是故說名生無自性性」——即一切有為行法皆由眾緣和合方得生起,由緣力故方有,非自然自有、自生之法。

【與三性之對應】本論承襲《解深密經》之說,進而以三性架構說明生無自性性:「云何諸法生無自性性?所謂諸法依他起相。何以故?此由依他緣力故有,非自然有,是故說名生無自性性」。生無自性性施設於依他起相之上,與施設於遍計所執相之相無自性性、施設於圓成實相之勝義無自性性相區別。

【勝義生菩薩之領解】本論以勝義生菩薩領解世尊言教作總結:「若即分別所行遍計所執相所依行相,是名依他起相。世尊依此施設諸法生無自性性,及一分勝義無自性性」。此處揭示生無自性性之體即依他起相,而依他起相亦得名為「一分勝義無自性性」,是本論中此二種無自性性相交涉之關鍵表述。

【獨特側面】一、生無自性性與依他起性互為表裏:以「依他起相」為體性名,以「生無自性性」為施設名,二名同指一事。二、所說密意:佛依「生無自性性、勝義無自性性」之密意而說「一切法皆如幻等」;本論以幻像為譬:「譬如幻像,生無自性性當知亦爾」,凸顯其緣生如幻、無自然實有之義。三、修證意涵:行者若於「生無自性性」中如實了知「相無自性性」及「勝義無自性性」,即可於依他起自性中不執著遍計所執自性相,進而正厭、正離欲、正解脫,超過煩惱、業、生三種雜染。

【術語記錄】本論用詞統一為「生無自性性」,未見其他異稱。與之配套見「依他起相」「依他起性」「依他起自性」三者並存:「依他起相」用於施設其名之脈絡;「依他起自性」「依他起性」見於修行領解之脈絡。又,本論關於三種無自性性之詳細問答,主要以引述《解深密經》中勝義生菩薩與世尊對話呈現,相關章節具經文引用之性質。
