What This Concept Means

In early Buddhist teachings preserved in the *Saṁyukta Āgama* (雜阿含經), Nirodha-dhātu (滅界, the Realm of Cessation) is a foundational soteriological concept. In a single sentence, it is defined as the ultimate realm of liberation where all conditioned formations come to complete cessation (一切行滅), a realm that must be directly realized through the meditative absorption of the cessation of existence/the five aggregates (有身滅正受).

To understand this concept deeply, we must unpack its classical structural components without oversimplifying them into vague modern synonyms:

1. Deconstructing the Term: *Nirodha* and *Dhātu*

* Dhātu (界): Rather than referring to a physical location or a boundary in time, *dhātu* here signifies "element," "underlying nature," or an experiential "realm/dimension." It denotes the intrinsic quality of ultimate reality. * Saṅkhāra (行 - Conditioned Formations/Volitional Impulses): In classical Buddhist doctrine, *saṅkhāra* refers to all conditioned, compounded, and volitional activities—the restless mental momentum, emotional drives, and cognitive compulsions that propel the cycle of existence (*saṁsāra*). * Nirodha-dhātu (滅界): It is the complete, unconditioned extinction (*nirodha*) of all *saṅkhāra*. It is not a temporary calm, but the permanent resolution and stilling of all conditioned friction.

2. The Triad of Liberation Realms (諸解脫界)

The classical texts situate *Nirodha-dhātu* within a complementary triad of "Realms of Liberation" (諸解脫界): 1. Pahāna-dhātu (斷界 - Realm of Severance): Defined as "severing all conditioned formations" (斷一切行). This represents the *active dimension* of cutting through conditioned driving forces. 2. Virāga-dhātu (無欲界 - Realm of Dispassion): Defined as "extinguishing craving and desire" (斷除愛欲). This represents the *emotional/volitional dimension* of uprooting attachment. 3. Nirodha-dhātu (滅界 - Realm of Cessation): Defined as "the cessation of all conditioned formations" (一切行滅). This is the *ultimate fruit and state*—the complete subsiding of all compounded activity once craving and active formations are severed.

While they emphasize different facets—action, emotional detachment, and ultimate state—they describe a unified experience of Nirvāṇa.

``` +-----------------------------------------------------------------------+ | THE TRIAD OF LIBERATION | +-----------------------------------------------------------------------+ | 1. Pahāna-dhātu (斷界) --> Active Cutting of Volitional Momentum | | 2. Virāga-dhātu (無欲界) --> Uprooting of Underlying Craving | | 3. Nirodha-dhātu (滅界) --> Ultimate Stilling of All Formations | +-----------------------------------------------------------------------+ ```

3. Epistemological Mechanism: Known via Contrast

How does one come to know something that is completely unconditioned? The *Saṁyukta Āgama* provides a precise set of one-to-one comparative analogies: * Light Realm (光界): Known only in contrast to *Darkness* (緣闇可知). * Pure Realm (淨界): Known only in contrast to *Impurity* (緣不淨可知). * Cessation Realm (滅界): Known only in contrast to Sakkāya (緣有身可知).

Here, Sakkāya (有身 - often translated as "embodied existence" or the "identity view") refers to the heavy, clinging identification with the five aggregates (*skandhas*): body, feeling, perception, mental formations, and consciousness. It is precisely through intimately observing the suffering, friction, and impermanence inherent in *Sakkāya* that the mind turns toward, recognizes, and values its total resolution: *Nirodha-dhātu*.

4. The Specific Meditative Path: Three Modes of Attainment

The classic texts strictly distinguish how different realms are attained through meditative absorptions (*samāpatti* / 正受): * Standard Realms (e.g., Light or Pure Realms): Attained through "ordinary self-directed absorptions" (自行正受). * The Highest Mundane Formless Realm (Neither-Perception-Nor-Non-Perception): Attained through the "First Being Absorption" (第一有正受, *bhavagga-samāpatti*), which represents the absolute peak of mundane, conditioned concentration. * Nirodha-dhātu (滅界): *Cannot* be attained through mundane concentration, no matter how deep. It is uniquely realized "in the meditative absorption of the cessation of existence" (於有身滅正受而得)—where all identification with the five aggregates completely collapses.

``` +--------------------------------------------------------------------------+ | MEDITATIVE PATHS AND THEIR ATTAINMENTS | +--------------------------------------------------------------------------+ | Light / Pure Realms --> Self-Directed Absorption (自行正受) | | Highest Formless Realm --> First Being Absorption (第一有正受) | | Nirodha-dhātu (滅界) --> Cessation of Existence Absorption | | (於有身滅正受而得) | +--------------------------------------------------------------------------+ ```

5. The Alternative Three-Realm Framework

While standard Buddhist cosmology divides the universe into the Desire Realm (欲界), Form Realm (色界), and Formless Realm (無色界), Venerable Ānanda highlights a crucial alternative framework in conversation with the householder Ghoṣita: Form Realm, Formless Realm, and Cessation Realm (色界、無色界、滅界).

In this structure, *Nirodha-dhātu* is set apart as the *only* unconditioned, transcendent realm. The text makes a stark warning: Even if a meditator achieves subtle formless states, if they "do not recognize the Cessation Realm" (不識滅界), they remain trapped in conditioned existence. Once their meditative power wears off, they inevitably "return to undergo existence" (還復受諸有). True liberation (*mind-liberation*, 心解脫) occurs only when one abandons attachment to the Form Realm, refuses to settle into the Formless Realm, and relies fully on *Nirodha-dhātu*.

6. Practicing the Path: Tranquility, Insight, and Equanimity

The teaching on *Nirodha-dhātu* was recorded as entirely unanimous across the Buddha, senior elders, and five hundred monks. To realize it, a practitioner must retreat to "empty places, under trees, or in quiet rooms" (空處、樹下、閑房) to cultivate Samatha-Vipassanā (止觀 - tranquility and insight). Furthermore, contemplating *Nirodha-dhātu* serves as the indispensable "nutriment" (āhāra / 食) that feeds and perfects the **Enlightenment Factor of Equanimity (捨覺分 / *Upekkhā-sambojjhaṅga*)**, bringing the mind to complete, unbiased freedom.


A Walkthrough in Daily Life

To understand how *Nirodha-dhātu* operates in the framework of liberation, we must trace how conditioned existence (*Sakkāya*) builds up in modern life, and where people routinely misidentify liberation.

Step 1: The Spark of *Sakkāya* and *Saṅkhāra* (The Morning Alarm)

Imagine waking up to an urgent notification on your smartphone: a critical issue has occurred at work, or an tense message arrives from your partner.

* The Aggregates React: Instantly, your body tightens (Form/色), an unpleasant wave of anxiety hits (Feeling/受), your brain identifies the situation as a dangerous conflict (Perception/想), and your mind immediately begins spinning strategies, defenses, and counter-arguments (Volitional Formations/行). Your awareness anchors tightly to this turmoil (Consciousness/識). * The Birth of Sakkāya: This entire reactive matrix is *Sakkāya* (有身). It is not just your physical flesh; it is the tight, defensive, self-centered identification with these five bubbling aggregates. The inner engine of *saṅkhāra* is now racing at maximum speed.

Step 2: The Modern Escape — Confusing Form/Formless States with Cessation

To escape this suffocating anxiety, modern urbanites turn to various coping mechanisms. This is precisely where the classical distinctions become crucial:

* Scenario A (Mundane Distraction / Light Absorption): You put on noise-canceling headphones, put on soft music, or scroll through soothing videos. You achieve a temporary state of calm. *This is merely altering sensory input—akin to a minor light/pure absorption (自行正受).* * Scenario B (The High-Performance / Deep Meditative Trap): You practice intense breathwork, reach a state of hyper-focus ("flow state"), or enter a deep, thoughtless state of meditation where body awareness disappears. You think: *"I felt totally weightless and calm; I have achieved Nirodha/Nirvana!"*

The Classical Corrective: This is the exact mistake warned against in the Āgamas. Entering a thoughtless or formless state of deep concentration corresponds to the "First Being Absorption" (第一有正受)—the peak of conditioned tranquility (Formless Realm). Because the underlying assumption of a "self" experiencing peace has not been dismantled by insight (*vipassanā*), the moment your meeting starts or another crisis hits, the friction instantly restarts ("還復受諸有"). You have not touched *Nirodha-dhātu*; you have merely put the engine in neutral while keeping the ignition on.

Step 3: Knowing Cessation via *Sakkāya* (The Turning Point)

How do you actually move toward *Nirodha-dhātu* in the middle of a busy, stressful life?

1. Observing the Darkness to Value the Light: You stop trying to manipulate your thoughts or force a calm state. Instead, you look directly at the burning nature of your anxiety. You observe: *"This feeling is impermanent. This mental planning (saṅkhāra) is exhausting. Clinging to this identity (Sakkāya) is pure suffering."* 2. The Subsiding of Formations: As insight (*vipassanā*) clearly sees that every mental movement is a conditioned, ungraspable burden, the mind naturally releases its grip. The volitional impulse to fight, defend, or build a self-narrative collapses. 3. A Glimpse of Nirodha-dhātu: In that moment of complete release, the mental momentum comes to a absolute halt (一切行滅). This is not blacking out, nor is it a blank void; it is the immediate, unconditioned experience of peace that arises when the heavy burden of *Sakkāya* drops away. You have used the observation of *Sakkāya* to know *Nirodha*.

``` +--------------------------------------------------------------------------------+ | DAILY LIFE WALKTHROUGH MAPPING | +--------------------------------------------------------------------------------+ | Mundane Trigger --> Morning notification causes physical/mental spike | | Sakkāya (有身) --> Clinging identification with the anxious aggregates | | Saṅkhāra (行) --> Restless mental spinning, strategizing, and defending | | False Escape --> Deep relaxation/flow state (Confused with Nirodha) | | Real Insight --> Observing Sakkāya's friction --> Volitional momentum | | ceases --> Glimpse of Nirodha-dhātu (一切行滅) | +--------------------------------------------------------------------------------+ ```


Why Contemporary People Need It

Modern civilization can be characterized as an endless machine for generating *saṅkhāra* (conditioned formations). Algorithms, infinite feeds, performance metrics, and generative AI are explicitly designed to capture attention, stimulate desire, and keep cognitive processing running at maximum capacity 24/7.

1. Beyond the "Self-Optimization" Trap

Most modern wellness culture treats meditation and mental health as tools for self-optimization. People learn mindfulness so they can lower their cortisol, improve their focus, stay calm under pressure, and ultimately return to work to produce more, consume more, and process more data.

In Buddhist terms, this is using subtle meditative states (Form/Formless states) to refurbish *Sakkāya* (the self-complex) so it can burn more fuel.

*Nirodha-dhātu* offers a radical, revolutionary paradigm shift: Real freedom is not about optimizing the machine; it is discovering the dimension where the machine completely comes to rest. It reminds us that true peace is not an accomplishment of the self, but the extinction of self-centered grasping.

2. The Limits of Neuroscience and AI Analogies

In contemporary discussions, scholars and meditators often compare *Nirodha-dhātu* or deep meditative states to modern scientific concepts: * Neuroscience: Researchers measure the down-regulation of the Default Mode Network (DMN) in the brain or record flatlined EEG waves during deep absorption. * Artificial Intelligence: Systems optimize algorithms to eliminate computational friction or enter zero-latency standby modes.

Crucial Limitations & Boundaries: While these analogies help us visualize physical mechanics, neural correlates are not the unconditioned realm. Neuroscience observes physical, biological inputs and outputs—which belong entirely to the *Form Aggregate* (色蘊) and *Consciousness Aggregate* (識蘊). An algorithm in standby mode is still a conditioned physical process (*saṅkhata*).

*Nirodha-dhātu* is radically unconditioned (*asaṅkhata*). Science measures the *conditioned shadow* cast on the physical body and brain when a meditator approaches cessation; it cannot measure or define the transcendent realization of liberation itself. Conflating neural metrics with *Nirodha-dhātu* mistakes the biological shadow for the unconditioned light.


Common Misunderstandings and Clarifications

Misunderstanding 1: "Nirodha-dhātu is a state of nihilistic extinction or physical death."

Clarification: Because *nirodha* translates to "cessation" or "extinction," modern readers often fear it means non-existence, annihilation, or a vegetative blank state.

This is a deep misinterpretation. What ceases in *Nirodha-dhātu* is not life or awareness, but the friction of ignorance, craving, and volitional compulsion (saṅkhāra). It is called a *dhātu* (realm/element) precisely because it is an actualizable, positive dimension of ultimate peace, security, and freedom. It is the living realization of Nirvāṇa—the ultimate health of the mind when the fever of attachment has subsided.

Misunderstanding 2: "Reaching a deep, thoughtless state in meditation means I have realized Nirodha-dhātu."

Clarification: As emphasized in the *Saṁyukta Āgama*, even the highest formless absorption—where thoughts, form, and subtle sensations disappear—can still be a form of mundane concentration ("First Being Absorption" / 第一有正受).

If a practitioner retains a subtle, subterranean identification with that peaceful state, they have not severed the root of *Sakkāya*. Once the concentration power fades, the latent tendencies (*anusaya*) awaken, and they "return to undergo existence" (還復受諸有). *Nirodha-dhātu* requires the sharp edge of wisdom (*vipassanā*) that cuts through identification with *all* conditioned states, including deep meditative calm.

Misunderstanding 3: "Severance (斷界), Dispassion (無欲界), and Cessation (滅界) are three completely different practices."

Clarification: It is easy to treat these three terms as separate, sequential steps or unrelated techniques. In reality, they describe the same awakening from three distinct vantage points: * Severance (斷界): The dynamic aspect of cutting off volitional momentum (*saṅkhāra*). * Dispassion (無欲界): The emotional aspect of cooling craving (*rāga*). * Cessation (滅界): The experiential reality when all turbulence has stopped.

They are unified in practice. When you cultivate tranquility and insight (*Samatha-Vipassanā*) in quiet reflection, you feed the Enlightenment Factor of Equanimity (捨覺分), allowing all three facets of liberation to mature simultaneously.

Canonical EntryAI-generated

一、定义与核心要义

在《杂阿含经》的教义体系中,「灭界」(nirodha-dhātu)是一个核心的解脱论概念。根据经中的明确定义,灭界即是指「一切行灭」的究竟状态。此处的「行」(saṅkhāra)泛指一切有为的造作、因缘生灭之法。灭界与「断界」(定义为「断一切行」)及「无欲界」(定义为「断除爱欲」)共同被归类为「诸解脱界」。这意味着,灭界不仅仅是一个抽象的哲学概念,而是修行者在断尽一切有为造作、平息生死扰动后所证得的实践性境界。它是涅槃在界(dhātu,即体性、领域或因缘)这一维度上的具体展现,代表着有为法的彻底熄灭与无为解脱的实现。

二、主要阐述

《杂阿含经》从多个维度对「灭界」进行了深入的阐述,主要包括其认知因缘、证得的正受路径、在三界架构中的定位,以及其在具体禅修实践中的应用。

1. 灭界的因缘与正受路径 在探讨如何了知与证得灭界时,经典提出了一种对比性的认知模式。佛陀指出,世间诸界的认识往往依赖于其对立面,例如「光界」是缘于「暗」而得以被了知,「净界」则是缘于「不净」而得以被了知。与此相类比,「灭界」的了知并非凭空而起,而是「缘有身可知」的。「有身」(sakkāya,即五阴炽盛的生命个体)是生死流转的具体呈现,正是因为有了对「有身」之苦迫与生灭的深刻观察,修行者才能反显并了知「有身熄灭」的灭界。 在证得的具体禅定路径上,经中区分了不同的「正受」(samāpatti,即等至、禅定状态)。一般的「光界」或「净界」等,修行者可以通过「自行正受」来获得;而无色界中极高的「非想非非想入处界」,则必须在「第一有正受」(即世间禅定的最高状态)中才能证得。然而,「灭界」作为超越世间的解脱境界,其证得方式截然不同,修行者必须「于有身灭正受而得」。这表明,只有在彻底熄灭对有身(五阴)的执着、达到有身灭尽的深沙门果正受中,灭界才能真正现前。

2. 三界划分与生死解脱的关键 在尊者阿难与瞿师罗长者的一场重要对话中,经典提出了一种不同于常见「欲界、色界、无色界」的「三界」划分方式,即「色界、无色界、灭界」。在这一架构中,「灭界」被置于超越色界与无色界的终极地位。 经中强调,认识并证得灭界是彻底断除生死轮回的决定性因素。如果色界与无色界的众生「不识灭界」,那么即使他们在禅定中取得了极高的成就(如升至无色界天),其本质上仍未脱离三界生死,一旦定力耗尽,依然会「还复受诸有」,继续在六道中轮回。相反,修行者若能断除对色界的贪爱,同时心不住著于无色界的微细禅定,并且依止「灭界」而达成「心解脱」,就能够「永离于生死」。这表明灭界是衡量是否真正解脱生死的唯一分水岭。

3. 止观修持与教法的高度统一 《杂阿含经》还特别强调了关于「灭界」教法在传承上的一致性。尊者阿难曾就「灭界」等解脱界的修持问题,先后咨问了上座比丘、五百比丘以及佛陀本人。令人瞩目的是,这三者给出的开示在法、句、义、味上完全一致,没有任何分歧。这证明了「灭界」的修持方法在早期佛教僧团中具有高度的共识。 根据这一高度统一的教导,修行者应当选择「空处、树下、闲房」等远离喧嚣的安静处所,专注思惟,通过修习「止观」(samatha-vipassanā)来成就包括灭界在内的诸解脱界。这说明灭界的证得并非盲目的信仰,而是建立在闲静处系统的止观禅修实践之上的。

三、不同部类与译本的表述差异

在《杂阿含经》(《雜阿含經》)的文本脉络中,对于「灭界」及相关概念的表述呈现出特定的名相组合与对比。 首先,在探讨「解脱界」的语境下,经文将「灭界」与「断界」、「无欲界」并提,分别对应「一切行灭」、「断一切行」与「断除爱欲」。这三者在名相上虽有侧重(「断」侧重于主动的断除,「无欲」侧重于贪爱的平息,「灭」侧重于有为造作的彻底熄灭),但在实质的解脱体验上是互通的。 其次,在与瞿师罗长者的对话中,经文则将「灭界」与「色界」、「无色界」并列为「三界」。这种名相组合在其他阿含经典或后世论典中,有时会被「欲界、色界、无色界」的常规三界所替代。此处特意将「灭界」列为第三界,旨在以无为的「灭界」来对比和超越有为的「色界」与「无色界」,凸显其出世间的特质。 此外,关于证得灭界的禅定状态,经文使用了「于有身灭正受而得」这一特殊表述,并将其与非想非非想入处界的「第一有正受」进行对比。在不同的译本或传承中,「有身灭」有时会被译为「五阴灭」或「五蕴灭」,「正受」亦有译为「等至」或「三昧」者。本经统一采用「有身灭正受」与「第一有正受」的对译,精准地勾勒出世间最高禅定与出世间解脱正受之间的本质区别。

四、与相关概念的关系

1. 与「断界」、「无欲界」的关系 「灭界」与「断界」、「无欲界」同属于「诸解脱界」。这三者构成了修行者走向涅槃的三个关键维度:断界侧重于对一切有为造作(行)的彻底斩断;无欲界侧重于对生死根本——贪爱(欲)的彻底拔除;而灭界则是这一切断除与无欲之后,所呈现出的「一切行灭」的寂静状态。三者相辅相成,共同指向解脱。

2. 与「舍觉分」的关系 在七觉支(七菩提分)的修行中,「灭界」扮演了极为关键的「食」(āhāra,即滋养、生起因缘)的角色。经中指出,「断界、无欲界、灭界」是令「舍觉分」得以生起和圆满的资粮。修行者如果能够对这三界进行专注、反复的思惟,就能够促使尚未生起的舍觉分得以生起;对于已经生起的舍觉分,则能使其重生成长,并最终达到增广与圆满的状态。这说明对灭界的思惟是培育平等、无执之「舍心」的最高法门。

3. 与「色界、无色界」的关系 在「色界、无色界、灭界」的三界架构中,灭界是唯一的出世间界。色界与无色界虽然代表了极高的禅定境界和天界存在,但由于未能证得「一切行灭」,其众生仍受制于细微的生灭法,因而无法免除轮回之苦。唯有以灭界为依止,达成「灭界心解脱」,才能彻底超越色界与无色界的局限,永离生死。

五、代表性原文引用

1. 关于灭界的定义与修持: 「尊者阿难问上座比丘、五百比丘及佛陀,皆答言:『阿难!一切行灭,是名灭界。……当于空处、树下、闲房思惟,修习止观,成就此界。』」

2. 关于灭界的因缘与正受: 「佛告比丘:『光界缘暗可知,净界缘不净可知,灭界缘有身可知。……灭界者,于有身灭正受而得。』」

3. 关于三界划分与生死解脱: 「尊者阿难告瞿师罗长者:『有三界。云何为三?色界、无色界、灭界。』」 「若色界、无色界众生不识灭界者,还复受诸有;若断色界、不住无色界,依灭界心解脱,永离于生死。」

4. 关于舍觉分之食: 「有断界、无欲界、灭界,此等专注思惟,未生舍觉分令生,已生舍觉分令重生,增长广大,是名舍觉分食。」

雜阿含經T0099 · 阿含部

《雜阿含經》以「滅界」一詞指稱一切苦及煩惱止滅的境界,其論述涵蓋多個側面,隨場合而有不同的開展方式。

在概念定位上,此經常將「滅界」與「斷界」、「無欲界」並列,合稱為「諸解脫界」——上座告訴阿難:「若斷界、無欲界、滅界,是名諸解脫界」,並直接定義「一切行滅,是名滅界」。此三界同時被視為七覺支中「捨覺分」之食——「有三界,謂斷界、無欲界、滅界。彼思惟,未生捨覺分令起,已生捨覺分重生令增廣,是名捨覺分食」,由此可見「滅界」在修行階位中具有獨特的功能。

在界地的分類上,阿難回答瞿師羅長者所問,明確說明:「有三界,色界、無色界、滅界,是名三界」。這顯示「滅界」與作為輪迴主體的色界、無色界並列為第三界,但性質迥異——前二者是繫縛之域,後者是解脫之域。其偈頌進一步闡發:「若色界眾生,及住無色界,不識滅界者,還復受諸有。若斷於色界,不住無色界,滅界心解脫,永離於生死」,即只有於色界斷除、不滯無色界,並於「滅界」中心得解脫者,才能永離生死輪迴。另一偈頌亦言:「知從欲界出,超踰於色界,一切行寂滅,勤修正方便。斷除一切愛,一切行滅盡,知一切有餘,不復轉還有」,指出從欲界出離、超過色界、一切行寂滅、斷除貪愛,方能不復退回諸有。又一偈頌:「曉了於欲界,色界亦復然,捨一切有餘,得無餘寂滅」,強調曉了欲界與色界之後,捨一切有餘,證得無餘寂滅。

在認識與修證方法上,佛陀於舍衛國祇樹給孤獨園說:「有光界、淨界、無量空入處界、無量識入處界、無所有入處界、非想非非想入處界,有滅界」——列舉種種界地,並隨後說明各界「何因緣可知」與「以何正受而得」。佛陀特別指出,「滅界者,緣有身可知」、「滅界者,於有身滅正受而得」,也就是說,「滅界」以「有身」之存在為其可知的因緣,並須透過「有身滅」的禪定正受才能證入。

綜合而言,《雜阿含經》論「滅界」兼及三層涵義:一為解脫界內涵之一(一切行滅),二為三界分類中超越輪迴的第三界,三為可「緣有身」而證入的定境。該經未使用其他異名,始終以「滅界」一詞貫串全文。

阿毘達磨俱舍論T1558 · 毘曇部

論及「滅界」之原文主要見於頌文及對應之論釋。《阿毘達磨俱舍論》以偈頌形式標舉「無為說三界」之說法,將「滅界」與「離界」、「斷界」並列為三種境界,而三者皆屬無為法之範疇。具體而言,頌文以「離界唯離貪,斷界斷餘結,滅界滅彼事」分別界定三者之內涵:離界唯以離貪為其作用,斷界以斷除其餘煩惱為其作用,而滅界則以滅除「彼事」——即隨眠所隨增之境事——為其作用。

論釋部分進一步闡明三界之體性與差別。論曰:「斷等三界,即分前說無為解脫以為自體」,明示此三界即為此前所說無為解脫之三分。換言之,三界並非另立之實體,而是對無為解脫依其不同作用所作之分別。論中再以「言離界者,謂但離貪;言斷界者,謂斷餘結;言滅界者,謂滅所餘貪等隨眠所隨增事故」具體說明三界之差異:離界之「唯離」表現其專以離貪為用之特點;斷界則承擔斷除其餘煩惱之功能;而滅界則針對所餘貪等之隨眠,以滅除其所隨增之事為其作用。

從整體論述觀之,《阿毘達磨俱舍論》對「滅界」之界定呈現以下幾項特徵:

第一,滅界與離界、斷界同屬無為解脫之三種分位,三者共同構成對「一切苦及煩惱止滅境界」之完整說明,其體性一致,作用各別。

第二,滅界之特殊作用在於「滅彼事」——即滅除「貪等隨眠所隨增之境事」。此處之「事」與前二界之「貪」與「餘結」相對應,顯示滅界所針對者為煩惱潛在勢力所隨增之境事,而非煩惱本身之現行。

第三,論中以「隨增」一詞描述隨眠與境界之關係,強調煩惱潛在勢力對境之增益作用,而滅界之作用即在於滅除此種隨增之關係,令煩惱不再增長境界。

關於術語,本論以「滅界」一詞指稱該概念,與之相關之重要表述尚包括「無為」、「無為解脫」、「隨眠」、「隨增事」等。其中「隨眠」特指貪等煩惱之潛在種子,「隨增事」則指隨眠所增益之境界對象,二者為理解滅界內涵之關鍵術語。論中亦云「經說三界即無為解脫」,顯示此三界之說乃本論引述經教之內容,而非論主之自創。

瑜伽師地論T1579 · 瑜伽部

《瑜伽師地論》對「滅界」之論述,集中於「五離繫品界」與「三界」「七界」之施設中,並兼及涅槃寂滅相與修學次第。

一、五離繫品界之施設與滅界定名 論云:「依出世道作意修中,有五離繫品界:一者斷界,二者無欲界,三者滅界,四者有餘依涅槃界,五者無餘依涅槃界。」其施設次第為:見道所斷諸行斷故名斷界;修道所斷諸行斷故名無欲界;即此唯有餘依故名有餘依涅槃界;此依滅故名為滅界,亦名無餘依涅槃界。由此「滅界」被安置於「有餘依滅盡」之位,與無餘依涅槃界相即。論中又以「於斷界未得為得勤修習故名修厭,於無欲界名修離欲,於滅界名修滅」明三界修學之階。

二、七界、三界之施設與「滅無上」 論以「界有三種」立色界、無色界、滅界;又立七界攝光明界、清淨界及四無色界,並別立滅界。七界之施設中明言:「由薩迦耶所有相應諸煩惱斷以為緣故,施設滅界為滅無上」,以薩迦耶相應諸煩惱斷為緣,建立滅界為「滅」之無上。又以「於一切相不思惟故,於無相界正思惟故,薩迦耶滅,由無相故,隨順獲得滅定、滅界」說入處。另以「內不出離、出離義故,當知建立有餘三界:色界、無色界、滅界」。

三、涅槃之寂滅相與無餘依之成立 論以「與一切依不相應,違背一切煩惱諸苦流轉,生起轉依所顯真無漏界」描述寂滅,引「苾芻永寂滅,名真安樂住」之說立「真無漏界」。於無餘依般涅槃界中,諸轉識等不復得生,唯餘清淨無為離垢真法界在。以先所生起諸行滅、自性滅壞諸行滅、一切煩惱永離繫三相說「寂滅」之成立,並示「非永無相」。又施設對治、現行、棄捨三種斷滅。

四、修覺分中之次第相資 修習覺分時,「未得斷界於其斷界正希求時名依遠離,未得無欲界名依離欲,未得滅界名依於滅」,展三界之次第相資。想修中,修涅槃道時於斷界、離欲界、滅界觀見最勝寂靜功德,修習斷想、離欲想、滅想。為斷邪行,施設「斷界及無欲界,若有餘依及無餘依」為妙甘露門。

總結:《瑜伽師地論》以「五離繫品界」為主幹定位「滅界」——此依滅故名為滅界,亦名無餘依涅槃界;以「七界」之「滅無上」顯其超越性;以三相諸行滅、無相界正思惟、薩迦耶相應諸煩惱斷等義理,闡明滅界之寂滅內涵。所用術語如「薩迦耶」(satkāya)、「苾芻」(bhikkhu)、「阿素洛」(asura)、「金剛喻定」、「真無漏界」、「轉依」、「異熟識」等,皆為本論特有之譯名形式。
