What This Concept Is Really Saying

In Buddhist discourse, "Neither Arising nor Ceasing" (*anutpādānirodha*; 不生不滅) is often mistaken for a state of static, glassy nothingness—a spiritual void where life's motion stops cold. In truth, it is the foundational insight into how reality actually exists.

To say a phenomenon is "neither arising nor ceasing" does not mean that things do not happen in the world. It means that **nothing ever arises as an independent, self-existent entity (*svabhāva*; 自性), and therefore, nothing is ever annihilated in absolute death.**

1. Composite Pseudonyms and the Emptiness of Self-Nature

The *Maha-prajñāpāramitā Sūtra* (*摩訶般若波羅蜜經*) explains that everything we perceive—from our physical senses (*rūpa*; 色) and mental states (*vedanā-saṃjñā-saṃskāra-vijñāna*; 受想行識) to trees, houses, and even the concepts of "Buddha" or "Enlightenment"—exists purely through **coalescence (*samagri*; 和合)** [12083]. They are "composite pseudonyms" (*和合假名*) [12083].

Consider a physical body: it is composed of a head, torso, limbs, organs, and blood cells. Is there a single, self-existent entity called "body" beneath these parts? No. Take away the parts, and the "body" vanishes. The term "body" is merely a linguistic convention (*但以名字說*) invented for earthly communication [12083].

The classical logic follows a precise chain of deduction: $$\text{Observe Lack of Self-Nature (*无自性*)} \longrightarrow \text{Phenomena are Unfounded (*非有 / 不成就*)} \longrightarrow \text{No Absolute Arising (*不生*)} \longrightarrow \text{No Absolute Ceasing (*不灭*)}$$

If something was never independently born in the first place, it can never truly die [17919]. Like a dream (*夢*), an echo (*響*), a shadow (*影*), or a mirage (*焰*) [12083], it appears vividly under specific conditions, yet lacks an intrinsic core.

``` Classical Chain of Logic (Mahāratnakūṭa Sūtra): [ Observed Phenomenon ] │ ▼ (Investigate intrinsic nature) [ Lacks Independent Self-Nature (無自性) ] │ ▼ (Cannot be established as a standalone entity) [ Unfounded / Non-Existent as an Entity (非有 / 不成就) ] │ ├───────────────────────────────┐ ▼ ▼ [ No Ultimate Arising (不生) ] [ No Ultimate Ceasing (不滅) ] │ │ └───────────────────────────────┘ │ ▼ [ Reality Beyond Birth & Death ] ```

2. Beyond Spatial Boundaries and the Three Times

Because phenomena lack independent arising, the *Maha-prajñāpāramitā Sūtra* emphasizes that "Neither Arising nor Ceasing" means **"No Fixed Spatial Location" (*無處所*)** [12768]. Form (*rūpa*) does not possess a locked, ultimate boundary in space [12768]. Furthermore, it transcends the timeline of past, present, and future (*三世不可得*) [17919].

When you realize that reality is inherently vast and unchanged by temporary compounding, you reach a state of **Unchanging Suchness (*真如*)**, free from gain or loss, free from grasping or rejecting [11562, 17919].

3. The Metaphor of Space (*Ākāśa*)

The *Mahāratnakūṭa Sūtra* (*大寶積經*) uses the metaphor of space (*虛空*) to illustrate this reality [14908]. Manjuśrī explains that when a world-ending fire consumes everything, space itself is neither burnt nor damaged, nor does it grasp onto the flames [14908]. The ultimate nature of all phenomena (*法性*) is precisely like space: inherently immaculate (*究竟清淨*), neither arising, nor ceasing, nor staying in the middle (*不生亦不滅,亦不住中間*) [11562, 17091].

4. The Manifestation of One's Own Mind

In the *Laṅkāvatāra Sūtra* (*楞伽阿跋多羅寶經*), "Neither Arising nor Ceasing" takes on an epistemological depth: it is an **epithet of the Tathāgata (*如來異名*) [8684] and is realized when one awakens to "The Self-Mind's Present Manifestation" (*自心現量*)** [8687].

Deluded sentient beings fail to realize that external objects are mere reflections produced by their own conditioned minds (*不識自心現妄想*) [8707]. They project external realities, attach to them, and generate suffering. When a seeker recognizes that external scenes are mentally projected phenomena, illusory fabrications cease to arise (*虛妄妄想不生*) [8687]. This state where false mental constructs stop arising and ceasing is the true definition of **Nirvana (*涅槃*) and "Unborn/Unceasing Liberation" (*妄想身轉解脱不滅*)** [8687, 8707].


A Walkthrough in Modern Life

To see how "Neither Arising nor Ceasing" operates, let us map it directly onto everyday modern experiences.

Scenario 1: The "Life-or-Death" Work Project

Imagine you are managing a high-stakes product launch at work.

* The Illusion of Absolute Arising & Ceasing: You think, *"This project was born on March 1st. It is MY project. If it launches successfully, my status is born; if it fails and gets canceled, my career is destroyed (ceased)."* You ride a roller coaster of intense anxiety and euphoria. * The Walkthrough of Reality: * **Composite Pseudonym (*和合假名*):** What actually is "the project"? It is a temporary bundle of Jira tickets, Slack messages, lines of code, server electricity, coffee-fueled meetings, and investor capital [12083]. No single component *is* the project. * **No Fixed Spatial Location (*無處所*):** Where does the project reside? In the cloud server? In your brain? In the corporate legal registry? It has no absolute, single physical location [12768]. * **No Absolute Arising or Ceasing (*不生不滅*):** When the project is canceled, did a solid entity named "Project" die? No. The coders moved to other tasks, the servers were reallocated, the ideas dissolved back into human memory. Because it was never an intrinsically self-existent thing (*無自性*), its "birth" was a conditional confluence, and its "death" is merely a re-sorting of conditions [12083, 17919]. * The Mismapping Point: People treat functional corporate constructs as concrete, self-existent entities. When you realize the project is an impermanent composite, you can work on it with total dedication without suffering a personal identity crisis when it dissolves.

Scenario 2: The Emotional Breakdown While Scrolling Social Media

You are scrolling through your phone late at night and see an ex-partner or a rival thriving. Suddenly, a wave of bitter jealousy rises in your chest.

* The Illusion: You feel as if a solid emotion called "Jealousy" was suddenly produced out of nowhere inside your heart, completely taking over your self-identity. * **The Walkthrough via Self-Mind's Present Manifestation (*自心現量*):** * **External Illusion (*自心現知外義*):** The phone screen merely emits blue light pixels. The brain interprets the pixels as a photograph; memory retrieves past events; ego-protection mechanisms fire neurons. * **Recognizing the Projection (*覺自心現量*):** The "jealousy" is not a solid object sitting inside your chest. It is a rapid chain reaction of memory habits (*妄想習氣*) [8707]. The moment you turn inward and observe the feeling without naming or grabbing it, you see it lacks self-nature (*無自性*) [17919]. * **Unborn and Unceasing (*不生不滅*):** Where did the jealousy come from? It didn't come from the phone (matter), nor was it waiting in your soul (a permanent entity). Because it had no independent point of origin (*不生*), it has no real substance to perish (*不滅*) [17919]. It dissolves into awareness like a wave collapsing back into the ocean. * The Mismapping Point: Most people mistake mental fabrications (*妄想*) for objective external realities. They think the *post* created their pain, failing to see that their mind projected the entire emotional scene [8707].

``` Modern Life Walkthrough: Observing an Emotional Trigger [ Blue Light Pixels on Phone ] │ ▼ (Conditioned Interpretation) [ Rapid Memory & Identity Habit Chains (妄想習氣) ] │ ▼ (Grasping it as a concrete reality) [ Illusion: "A solid monster of Jealousy was born inside me!" ] ───────────────────────────────────────────────────────────── ▲ (Apply the Insight of Self-Mind's Present Manifestation) │ [ Direct Observation: Pure Mind Projection (自心現量) ] │ ▼ (Examine its origin) [ Has no independent physical or mental source (無自性/不生) ] │ ▼ (Result) [ Emotional construct dissolves into quiet awareness (虛妄妄想不生 -> 涅槃) ] ```


Why Contemporary People Need It

Modern society is built on extreme hyper-quantification and digital permanence. We track likes, stock portfolios, age metrics, performance reviews, and step counts. This culture forces us into a frantic binary of Existential Arising vs. Devastating Ceasing ("I must gain X, or I am reduced to zero").

1. Liberation from Algorithmic & Existential Burnout

In an age governed by real-time algorithms, our minds are trained to see life as a series of discrete creations and deletions—posts going viral (arising) or being canceled/forgotten (ceasing). This creates chronic mental fatigue.

The teaching of "Neither Arising nor Ceasing" provides a profound cognitive reset. It invites us to see that the digital profiles, social statuses, and self-images we frantically maintain are all "composite pseudonyms" (*和合假名*) [12083]. They possess functional utility, but zero ultimate self-nature. Realizing this allows one to engage with modern life playously—like an actor on stage—rather than living in perpetual terror of loss.

2. Insightful Analogy: Virtual Reality & Large Language Models

Consider a modern analogy using AI and virtual reality:

* Large Language Models (LLMs): When an AI generates a poetic response, where did that poem "live" before appearing on your screen? It wasn't stored as a finished document in a database; nor was it created out of nothing. It emerged through the mathematical convergence of weights, vectors, parameters, and your prompt. When you close the browser window, the text vanishes. Did a soul die? No. The underlying matrix remains untouched. * Virtual Reality (VR): When you wear a VR headset, you might see a towering dragon breathing fire. You feel heart-pounding fear. Yet, the dragon has "no spatial location" (*無處所*) [12768]. It is a projection of code mapped to light lenses.

*Boundary Note:* While computational matrices and VR engines help us conceptualize how complex phenomena appear without intrinsic substance, they are not identical to Buddhist Emptiness. Computer code relies on physical silicon chips, electrical grids, and human programmers—which themselves are conditioned phenomena. Buddhist "Neither Arising nor Ceasing" cuts deeper: it points to the absolute, unconditioned reality (*Asaṃskṛta*; 無為) that transcends all physical or digital substrates.


Common Misinterpretations & Clarifications

To truly understand "Neither Arising nor Ceasing," we must dismantle several pervasive misunderstandings held by beginners and outside philosophers alike.

``` ┌──────────────────────────────────────────────────────────────────────────┐ │ CRITICAL DISTINCTION │ ├──────────────────────────────────────────────────────────────────────────┤ │ Non-Buddhist / Eternalist View (外道有無品): │ │ "There is a core, unchangeable eternal entity (Soul/God/Atom) │ │ underneath all changes that never dies." │ ├──────────────────────────────────────────────────────────────────────────┤ │ Authentic Buddhist View (離有無品 / 自性本空): │ │ "Phenomena are like mirages. Because no independent entity ever arose │ │ in the first place, nothing actually undergoes ultimate death." │ └──────────────────────────────────────────────────────────────────────────┘ ```

Misinterpretation 1: "Neither arising nor ceasing means nothing matters, or things literally don't exist." (Nihilism / 惡取空)

* Clarification: "Neither Arising nor Ceasing" does *not* deny cause and effect (*karma*) or conventional reality (*saṃvṛti-satya*). * The *Maha-prajñāpāramitā Sūtra* explicitly states that names and forms exist **as composite pseudonyms (*和合假名*)** for practical life [12083]. Pain feels real, actions produce consequences. What is denied is not the *appearance* of things, but their *intrinsic, independent existence* (*svabhāva*). Water still quenches thirst, even if water lacks a solid, permanent self-nature.

Misinterpretation 2: Confusing Buddhist Non-Arising with Non-Buddhist Eternalism (外道「有無品」之別)

* Clarification: In the *Laṅkāvatāra Sūtra*, the disciple Mahāmati asks: *"Non-Buddhist philosophers also claim that their primordial cause (such as subtle atoms, a creator god, or eternal nature) is uncreated and imperishable [8686, 8687]. How does the Buddha's teaching differ?"* [8686, 8687] * The Buddha gives a decisive distinction: 1. **Non-Buddhist views fall into the "Category of Being and Non-Being" (*有無品*) [8687].** They postulate a real, self-existent core entity (*有性自性*) and claim *that specific entity* never dies [8687]. 2. **The Buddha's teaching transcends Being and Non-Being (*離有無品*) [8687].** It asserts "Neither Existence nor Non-Existence" (*非性非無性*) [8687]. The Buddha does not offer a solid "eternal soul" or "substance." Instead, he points out that all things are like dreams and mirages (*如幻夢*) [8687]. Because no substance was ever brought into true, independent existence (*無生作非性*) [8410], the concept of its destruction is an illusion.

Misinterpretation 3: Mistaking Words for the Experience (Mistaking the Finger for the Moon)

* Clarification: The *Laṅkāvatāra Sūtra* cautions that "If one does not skillfully practice 'Neither Arising nor Ceasing,' it becomes an unwholesome trap" (*不生不滅,不方便修,則為不善*) [8686]. * People often treat the phrase "Neither Arising nor Ceasing" as an intellectual philosophy or a dogma to recite. The sūtra uses the famous **"Finger Pointing at the Moon" metaphor (*指端示物*)** [8686]: A person points their finger at the moon to show it to a child. If the child looks only at the fingertip (the literal words and concept), they miss the moon (the living, non-conceptual experience of ultimate reality) [8686]. * Literal words are tied to conceptual discrimination (*妄想*), which accumulates worldly birth and death (*積集生死*) [8686]. The ultimate truth (*第一義*) is subtle, quiet, and beyond textual debate [8686].

Summary of the Liberation Path

"Neither Arising nor Ceasing" is not a dry theoretical label. In the liberation道 (path of awakening), it is the ultimate shield and sword: * When you observe outer chaos, **Space Metaphor (*虛空之喻*)** reminds you that your clear, intrinsic awareness is never burned by worldly fires [14908]. * When inner emotional storms rage, **Self-Mind's Present Manifestation (*自心現量*)** reveals that feelings are self-projected illusions lacking an originating anchor [8687, 8707]. * By viewing all compounded life through **Composite Pseudonyms (*和合假名*) and Self-Nature Emptiness (*自相空*)**, the mind stops grasping, stops fearing, steps out of the illusion of birth and death, and abides in deep, unshakeable peace [12083, 15635].

Canonical EntryAI-generated

一、定义与核心要义

「不生不滅」(anutpādānirodha)是佛教阐释诸法实相的核心概念。它并非指一种抽象的虚无,而是指一切诸法因缘和合、自性本空,超越了生起与消灭、存在与不存在的对立,呈现出本自清净、常住不动的真实状态。在不同经典中,它被赋予了诸法体性、如来异名、自心现量以及涅槃境界等多重深意。

二、主要阐述

1. 和合假名与自性本空 诸法皆是因缘和合而有,其本质是不生不灭的,世间名字仅为沟通而设的假名。如人体各部和合为身、草木枝叶和合,乃至梦、影、幻、化等,皆是「但以名字说」且「不生不灭」。从自性来看,见诸法无自性则见法非有,非有则不成就,不成就则「不生」,不生则「不灭」。

2. 超越空间、三世与戏论 不生不灭意味着「无处所」。一切法(如色、受想行识、入界等)皆因不生不灭而无处所,超越了空间局限。同时,不生不灭的状态超越了过去、现在、未来(三世不可得),无得无失,是真如的不变不异。在此状态中,无有得者与受者,菩萨应不取不舍,不见少法生灭,远离一切戏论。

3. 虚空之喻与常住体性 诸法体性「无有所作亦无变异,不生不灭不出不离」。文殊师利以「虚空」为喻,正如火灾起时虚空不被烧、无所受持,诸法体性亦是不生不灭、无所受持。诸法自性本就「不生亦不灭,亦不住中间」。

4. 自心现量与妄想息灭 证得不生不灭的关键在于觉知「自心现量」。众生因不识自心现妄想而生起执着,若能了知外境皆是自心显现,妄想即会熄灭。当虚妄妄想不生、不起不灭时,即是「无相」与「涅槃」。通过灭除无始虚伪过恶妄想习气,实现「妄想身转」,便能证得「解脱不灭」。

5. 远离言说与方便修持 不生不灭若不善方便修持则为不善,修行者不应随言语字句起计着。如「指端示物」之喻,执着于言说(指头)便无法获得第一实义(所指之物)。真实义远离文字,是微妙寂静之因,而言说与妄想相合只会积集生死。

三、不同部类与译本的表述差异

1. 五蕴的表述 《摩訶般若波羅蜜經》(《摩訶般若波羅蜜經》)在阐述不生不灭时,未使用「五蕴」或「五阴」等集体称号,而是具体列出「色」与「受想行識」。

2. 空间与否定性术语 《摩訶般若波羅蜜經》频繁使用「無處所」来界定不生不灭的超越性,并将其与「不作、不出、不得不垢不淨」、「不增不減」 等并列。

3. 如来异名与唯识术语 《楞伽阿跋多羅寶經》(《楞伽阿跋多羅寶經》)将不生不灭直接视为如来的异名,并使用了独特的唯识宗派术语,如「意生法身如來」、「自心現量」与「自心現知外義」、「有無品」、「爾炎」(指所境) 以及「妄想身轉解脫不滅」。

4. 苦灭谛的表述 《大寶積經》(《大寶積經》)在论述苦灭谛时,虽未直接使用「不生不滅」字眼,但将其描述为「無始無作、無起無盡、常住不動、本性清淨」。

四、与相关概念的关系

1. 与「自相空」的关系 不生不灭学即是不增不减学,其核心在于「不起不作」,而达到这一状态的方法是观察「诸法自相空」(如色相空、受想行识相空等)。

2. 与「涅槃」及「苦灭谛」的关系 妄想不生、不起不灭的无相状态即是「涅槃」。苦灭圣谛离有为相而「性常住」,是谛、是常、是归依处。

3. 与外道「不生不灭」的区别 外道的主张堕于「有無品」,认为存在一个实有的实体或自性(「有性自性」)。而佛法所说的「不生不灭」则「離有無品」,「非性非無性」,视一切法如幻梦,无真实生灭。「無生作非性」,若执着有性则被生死所摄。

五、代表性原文引用

1. 《摩訶般若波羅蜜經》:「不生不滅義無處所。色不生不滅故無處所,受想行識不生不滅故無處所……」 2. 《大寶積經》:「一切諸法無有所作亦無變異,不生不滅不出不離,何以故?一切諸法究竟清淨故。」 又云:「不生亦不滅,亦不住中間」,「無生亦無滅,諸法自性爾」。 3. 《楞伽阿跋多羅寶經》:「不生不滅者,大慧!此是如來異名。」 又云:「大慧!若覺自心現量時,虛妄妄想不生,安隱快樂,世事永息。」

摩訶般若波羅蜜經T0223 · 般若部

《摩訶般若波羅蜜經》論「不生不滅」,貫穿名相、處所、歸趣、修學四個層面,形成一套以「和合故有」為起點、以「自相空」為觀法的完整論述。

一、和合故有,唯名字說。經中反覆以「和合故有」作為不生不滅的直接理據:耳鼻舌身意、色聲香味觸法、眼界乃至意識界,皆因和合而有,「是亦不生不滅,但以世間名字故說」。經文更以內身(頭、項、肩、臂等)、外物(草木枝葉莖節)、過去諸佛名、夢響影幻焰及佛所化事為喻,說明法與名字皆「不生不滅,非內、非外、非中間住」。此處術語上,本經以「名假施設、受假施設、法假施設」三假統攝一切施設,並強調菩薩行般若時「不見色名字是常……不見色名字無常」,即名字本身超越常與無常的對立。

二、不生不滅義無處所。經文將不生不滅與「無處所」結合:「如不生不滅義無處所,菩薩摩訶薩行般若波羅蜜時,菩薩句義無所有亦如是」。須菩提追問「何法不生不滅故無處所」,佛答:色、受想行識、入界、四念處乃至十八不共法,皆「不生不滅故無處所」。此處本經以「無處所」一詞標示不生不滅的無住性格,並以「日出時無有黑闇」「劫燒時無一切物」為喻,強調菩薩句義之無所有與不生不滅同構。

三、一切法趣不生不滅。經文以「趣」字框架統攝諸法實相:「一切法趣無所有、不生不滅不垢不淨,是趣不過。何以故?無所有、不生不滅不垢不淨中趣不趣不可得故」。不生不滅與無所有、不垢不淨並列為一切法所趣之實相,而此「趣」本身亦不可得——趣與不趣雙泯,方為「是趣不過」。同段更以夢、幻、響、影、化等喻及「不來不去、不入不出、不合不散、不著不斷」等否定對舉,鋪展不生不滅的無邊義域。

四、不生不滅即修學。經中佛與須菩提以層層追問揭示修學內涵:菩薩應學色乃至一切種智「不增不減」,而「不增不減」之學即是「不生不滅故學」;不生不滅學即「不起不作,諸行業若有若無」;不起不作即「觀諸法自相空」。由此,不生不滅從實相描述轉為觀行綱領:「應觀色,色相空;應觀受想行識,識相空;應觀眼,眼相空;乃至意識界,意識界相空」,四禪乃至滅受想定亦皆「相空」。本經以「自相空」一詞收攝此觀法,有別於他經或偏言「性空」「無自性」者。

綜觀本經,不生不滅並非脫離緣起的斷滅,而是即和合、即名字、即無處所、即不可說而顯的諸法實相;在術語上,本經特重「名字」「和合」「假施設」「自相空」「無處所」「趣」等詞,構成其獨特的般若話語。

大寶積經T0310 · 寶積部

《大寶積經》為大部會編,各會論述「不生不滅」之切入角度與術語形式不一,以下逐會記之。

一、無邊莊嚴會以「無所得」與「究竟清淨」為樞紐。經云如來證得一切諸法如實本性,然此本性不可宣說,「一切諸法無所有故」;繼而總括:「如來說一切法,無有所作亦無變異,不生不滅不出不離,一切諸法究竟清淨故。」 此處「不生不滅」與「不出不離」並舉,歸結於「究竟清淨」,非單純遮遣生滅,而是將不生不滅收攝於清淨本性。同會又從「得」之角度推論:「一切諸法由不生故無有得者」,以不生故無受者、無可證。末段更明言菩薩若解了此法,「亦不見有少法生滅,無有戲論非無戲論」,以「不見少法生滅」為修證落點。

二、文殊師利所問會以「無生無滅」為術語,置於一連串遮詮之中:「無生無滅、無因無緣、無去無來、無有眾生非無眾生、無污染無白淨、無生死無涅槃」,謂諸佛世尊「亦不分別體性而說法」。此會特色在於將無生無滅與無因無緣、無生死無涅槃等對舉,不單遮生滅,亦遮因果、染淨、生死涅槃之分別,呈全面遮詮之姿。

三、法界體性無分別會(經中自題「說法界體性無分別」)以虛空為喻:文殊師利言「如虛空體性,是一切法亦復如是,而是諸法不生不滅。若法無生無有滅者,亦無受持。諸法體性無受持故,如法體性,受持諸法亦復如是」。此處先立「不生不滅」,再轉為「無生無有滅」,要旨落在「無受持」——法性既無生滅,則受持此經亦當如法體性,無能受所持。術語上同一會中「不生不滅」與「無生無有滅」互見。

四、外道問會以層層推衍之論證鏈呈現:觀慢不可得→無一法可得→諸法無自性→見法非有→非有故不成就→「不成就故,知即不生。若不生者,知彼不滅。若不生不滅者,彼非可說」→非三世→未曾有得有失→「一切法平等」→「一切法是真如不變不異」。此會獨特處在於從具體煩惱(憍慢)之觀察入手,逐步推至不生不滅,再收歸真如平等,且明言不生不滅即「非可說」,超越三世言詮。

五、偈頌以「諸法無生滅」為諸法實相,與「無上忍」相聯:「能得無上忍,忍諸法實相,諸法無生滅,能善通其理」。此處術語作「無生滅」(省略重疊之「不」字),且將通達無生滅定位為忍(安忍、認可)之對象,即諸佛道之內容。

六、文殊般若會以法界、不思議、般若波羅蜜三者互即為框架:「不思議界即無生無滅界,無生無滅界即不思議界」;又云「無依無住即無生無滅,無生無滅即是有為無為功德」。此會術語作「無生無滅界」,將不生不滅提升為「界」(法界之等流),且明言無生無滅並非斷滅,而即是有為無為功德之體;末云「不取生滅及諸起作,亦不斷不常」,以不取、不斷不常收束,避免墮於斷見。

綜觀全經,術語形式有三:「不生不滅」(無邊莊嚴會、法界體性會、外道問會)、「無生無滅」(文殊所問會、文殊般若會)、「無生滅」(偈頌),另有「無生無有滅」之展開式。論述角度涵蓋:以究竟清淨為歸、以全面遮詮為方法、以虛空喻顯無受持、以觀煩惱推至真如、以忍為證入、以法界不思議互即為框架,各會側重不同而互不矛盾。

大般涅槃經(北本)T0374 · 涅槃部

《大般涅槃經(北本)》論「不生不滅」,貫通兩個層面:一是如來自身的體性,二是眾生聞法後所證得的果德。

一、如來以「不生不滅」為深義之體性。經中佛以大海八不思議喻涅槃經之八種殊勝,其第八「不增不減」下,佛自釋云:「若言如來不生不滅名為深者」,明確將「不生不滅」標舉為如來之所以為「深」的根據。此處「不生不滅」與「無邊際」「無始終」「非色」「非作」「常住」並列,同為「不增不減」的內涵,亦即涅槃經體性之描述。值得注意的是,經文先說「不生滅故」,後於師子吼追問時轉為完整形式「不生不滅」,二者同義而字面略有縮展。

二、眾生聞大涅槃祕藏即得「不生滅」。偈頌中以醫藥為喻:世間醫師所治之病「雖差還復生」,如來所治者「畢竟不復發」;如來以「甘露藥」施諸眾生,眾生服已「不死亦不生」。緊接著點明機制:「如來今為我,演說大涅槃,眾生聞祕藏,即得不生滅。」 此處術語作「不生滅」(三字),是偈頌體裁的省縮,與散文體的「不生不滅」所指相同。經文將「不生滅」定位為聞法之果——非漸次修得,而是聞祕藏「即得」,強調頓入義。

三、本經獨特的論述框架。其一,以「大醫王」與「甘露藥」的醫療隱喻承載不生不滅義:生死是病,如來是醫,涅槃教法是藥,服藥(聞法)則病根永斷,不復生滅。其二,以大海八不思議中的「不增不減」攝「不生滅」,使不生不滅不僅是如來體性,也是涅槃經本身的屬性——「是故此經如彼大海有八不思議」。其三,師子吼從「四種生」(卵、胎、濕、化)追問:如來既得不生不滅、得八自在,何以不取化生?佛答以劫初眾生雖化生而煩惱未發、身心非器,故如來不出世。此段將「不生不滅」與「四生」對舉,暗示如來之不生不滅並非四生中任何一類,而是超越四生框架的常住。

四、術語形式小結。本經散文用「不生不滅」與「不生滅故」,偈頌用「不生滅」及「不死亦不生」,所指一致。經中未見以「無生」「無生滅」等異稱替代,亦未將此義歸入「法性」「真如」等他經常見之術語框架,而是直接繫屬於「如來」與「涅槃經」兩個主詞之下。
