这个概念在说什么 (What This Concept Is Talking About)

In the architecture of Buddhist liberation, Śūnyatā-samādhi (空三昧, *Kōng Sānmèi*—the Samādhi of Emptiness) is not a passive mental blankness, nor is it a state of emotional numbness. It represents a fundamental shift in perception—a meditative absorption (*samādhi*) born from deeply observing that no phenomena possess an intrinsic, independent self (*svabhāva*).

To understand its position on the path to liberation (*mārga*), one must look at how classical texts position it within the Three Doors of Liberation (三解脱门, *Sān Jiětuō Mén*): 1. Śūnyatā-samādhi (空三昧): Corresponds to the "Phase of Concentration" (定相, *Dìng Xiàng*). It directly dismantles the false perception of an enduring self (*ātman*) or self-belonging (*mamatā*). 2. Animitta-samādhi (无相三昧, *Wúxiàng Sānmèi*—Signlessness): Corresponds to the "Phase of Equanimity" (捨相, *Shě Xiàng*). It extinguishes the mental grasping at signifiers, forms, and conceptual labels. 3. Appaṇihita-samādhi (无愿三昧, *Wúyuàn Sānmèi*—Wishlessness/Aimlessness): Corresponds to the "Phase of Wisdom" (慧相, *Huì Xiàng*). It stops the forward projection of craving for future states or achievements.

Together, these three gates form the bridge from conditioned existence (*saṃskṛta*) to Unconditioned Peace (*nirvāṇa*). *Śūnyatā-samādhi* serves as the foundation: by inspecting reality and discovering that nothing holds a self-existent core, the mind breaks free from the delusion of possession and control.

``` +-----------------------------------------------------------------------------------+ | THE THREE DOORS OF LIBERATION | +------------------------------------+----------------------------------------------+ | Śūnyatā-samādhi (空三昧) | Phase of Concentration (定相) | | Deconstructs Self & Possessions | "All phenomena are inherently empty." | +------------------------------------+----------------------------------------------+ | Animitta-samādhi (无相三昧) | Phase of Equanimity (捨相) | | Deconstructs Conceptual Signs | "No signs or labels to hold onto." | +------------------------------------+----------------------------------------------+ | Appaṇihita-samādhi (无愿三昧) | Phase of Wisdom (慧相) | | Deconstructs Craving & Projection | "Nothing to seek, wish for, or achieve." | +------------------------------------+----------------------------------------------+ ```

1. The Core Object of Contemplation: "Self-Emptiness" of All Dharma

*Śūnyatā-samādhi* is not built by taking something solid and making it empty. Rather, as expressed in the *Māhāratnakūṭa Sūtra* (*Dà Bǎojī Jīng*), "The nature of phenomena is self-empty" (法性自空, *Fǎxìng zì kōng*). Emptiness is not an added quality; reality has always been self-empty across past, future, and present (*前際空、後際空、中際亦空*).

In classical sūtras like the *Mahāsaṃnipāta Sūtra* (*Dàfāngděng Dàjí Jīng*), this contemplation is systematically unpacked into the Seven Emptinesses (七种空, *Qī Zhǒng Kōng*): - Emptiness of the Aggregates (阴空 / 五阴空): Observing form, sensation, perception, mental formations, and consciousness as void of an internal ruler or permanent owner. - Emptiness of Realms and Spheres (界空与入空): Deconstructing the 18 realms (*dhātu*) and 12 sense spheres (*āyatana*). - Emptiness of Truths (谛空): Realizing that even the Four Noble Truths contain nothing to grasp or abandon as fixed entities. - Emptiness of Dependent Origination (因缘空): Seeing that the 12 links of causation operate without a personal director (*“无命、无主”*). - Emptiness of Nature (性空): Recognizing the essential non-arising nature of sense faculties. - Emptiness of Phenomena and Reality (法空与实空): Seeing all phenomena as devoid of conceptual deliberation (*vitarka-vicāra*), a soul, or ownership. - Ultimate Emptiness (一切皆空): As expanded in the *Mahāparinirvāṇa Sūtra* (*Dà Bānnièpán Jīng*), not only are physical forms empty, but even the Six Perfections (*pāramitās*), the Tathāgata, and Parinirvāṇa itself are ultimately empty of inherent, conceptual existence (*“见一切法性无所有”*).

2. Practical Entry Points

How does a practitioner enter *Śūnyatā-samādhi*? Canonical texts record multiple pathways: 1. Ānāpānasmṛti (入出息念—Mindfulness of Breathing): Through the six stages—counting (*gaṇanā*), following (*anugama*), stopping (*sthāpanā*), contemplating (*vikṣaṇā*), turning back (*vivarta*), and purification (*pariśuddhi*)—one arrives at the "Pristine Empty Samādhi" (净空三昧). 2. Contemplation of Impurity & Bones (不净观与白骨观): Visualizing the body reduced to bones, then powder, then scattered into dust by wind, until nothing remains except infinite space, leading directly into emptiness. 3. Daily Action of Non-Grasping (具足行空): Practicing generosity, ethics, or patience without forming conceptual labels (*不想*)—neither identifying as a "doer" nor craving spiritual fruition or "mind of the Way." 4. Purification of Residual Karma: Practicing *Śūnyatā-samādhi* in quiet seclusion when subtle karmic obstacles arise, clearing mental deposits without leaving traces.

3. The Mahāyāna Dynamic: Compassion without Attachment

Unlike a quietist escape, the Mahāyāna tradition highlights a radical dimension: Not abandoning sentient beings (不舍众生). A Bodhisattva cultivates *Śūnyatā-samādhi* specifically to tame and guide living beings (*调伏众生*).

Because a Bodhisattva deeply understands emptiness, they can view all beings like an only child. They work tirelessly to eliminate suffering for others, yet never entertain the egoic thought: *"I am severing the afflictions of living beings."* Like a forest that remains unbothered whether it is growing, being cut down, or washed away by water, the practitioner resting in *Śūnyatā-samādhi* abides in unconditional equanimity—devoid of hatred or selfish delight.

4. The Classic Allegories: Avoiding the Trap of "Emptiness-View" (*Śūnyatā-dṛṣṭi*)

The classics issue a severe warning: to misinterpret emptiness as a doctrine or an ideology—falling into Emptiness-View (空见, *Kōng Jiàn*)—is the most dangerous trap in spirituality. As the *Māhāratnakūṭa Sūtra* warns: > *"Better to hold a view of self as vast as Mount Sumeru than to hold a view of emptiness with spiritual pride. Why? All wrong views can be liberated through emptiness, but if one clings to emptiness itself as a view, nothing can cure it."*

To illustrate this, the canon provides four precise allegories:

``` +-----------------------------------------------------------------------------------+ | FOUR ALLEGORIES OF THE "EMPTINESS TRAP" | +---------------------+-------------------------------------------------------------+ | Classical Metaphor | Spiritual Meaning / Trap | +---------------------+-------------------------------------------------------------+ | 1. Medicine Kept | Taking medicine to cure a disease, but the medicine remains | | Inside (药不出体)| stuck in the body, creating a worse, incurable illness. | +---------------------+-------------------------------------------------------------+ | 2. Fearing Space | Panicking and trying to escape empty space, failing to see | | (畏虚空) | that one is already walking inside space at every moment. | +---------------------+-------------------------------------------------------------+ | 3. Painter Scared | An artist painting a terrifying demon image, then falling | | of Demon (画师自惧)| to the floor in genuine terror of their own creation. | +---------------------+-------------------------------------------------------------+ | 4. Two Sticks Fire | Two wooden sticks rubbing together create fire, which then | | (两木相磨) | consumes both sticks. The contemplation of emptiness | | / Magician | dissolves all views and ultimately dissolves itself. | +---------------------+-------------------------------------------------------------+ ```

1. The Medicine Remaining in the Body (*药不出体*): Medicine cures sickness. But if the medicine stays trapped in the stomach, it becomes a fatal toxicity. Emptiness cures attachments; if you digest emptiness into a new dogmatic identity, the cure becomes the poison. 2. Fearing Empty Space (*畏虚空*): A person becomes terrified of voidness and runs around screaming to escape space, completely oblivious that every step they take occurs within space itself. 3. The Painter Frightened by His Own Demon (*画师自惧*): A painter paints a terrifying demon on a wall, forgets it is just paint, and faints in horror. Similarly, the mind invents concepts of "emptiness" or "nothingness" and becomes terrified of them. 4. Two Wooden Sticks Rubbing Together / Magician's Illusion (*两木相磨 / 幻师自食*): Two sticks rub together to ignite a fire; the resulting flame burns away both sticks until nothing remains. Likewise, true contemplation of emptiness (*samādhi*) burns away afflictions and then burns away *itself*, leaving zero conceptual residue.

Through *Śūnyatā-samādhi*, the practitioner abandons fixed definitions of phenomena (*不见法性*) and directly beholds the unconditioned reality—Buddha-nature (见佛性).


生活里的走查 (A Walkthrough in Daily Life)

To see how *Śūnyatā-samādhi* operates, let us walk through a typical day in contemporary life—examining our habits across modern scenarios and seeing where our minds construct delusion vs. where emptiness liberates.

``` +-----------------------------------------------------------------------------------+ | DAILY LIFE WALKTHROUGH: EMOTION VS. SAMĀDHI | +-----------------+---------------------------------+-------------------------------+ | Scenario | Delusion / Egoic Reaction | Śūnyatā-samādhi Insight | +-----------------+---------------------------------+-------------------------------+ | Morning Commute | "They cut ME off!" | Traffic is a fluid web of | | & Traffic | Personalizes impersonal events. | conditions. No core enemy. | +-----------------+---------------------------------+-------------------------------+ | Scrolling | Social comparison; anxiety over | Feed is algorithmic prompts | | Social Media | likes, views, and status. | touching ephemeral triggers. | +-----------------+---------------------------------+-------------------------------+ | Overtime Work | "MY hard work was ignored!" | Projects are aggregation of | | & Burnout | Identity attached to output. | effort, timing, and causes. | +-----------------+---------------------------------+-------------------------------+ | Conflict in | "You ALWAYS do this to me!" | Aggression arises from inner | | Relationships | Solidifies partner as a foe. | fear/causes; no fixed villain.| +-----------------+---------------------------------+-------------------------------+ ```

Scenario 1: The Morning Commute & Delayed Transit

- The Delusive Habit: You are stuck on a packed subway train or in bumper-to-bumper traffic. Someone cuts you off or bumps into your shoulder. Instantly, the mind generates a narrative: *"Why does this always happen to ME? People are so rude."* You internalize the delay as an attack on your personal timeline. - **Applying *Śūnyatā-samādhi***: 1. *Deconstruct the Aggregates (阴空)*: Look at the sensation of frustration. Is there a permanent "I" being offended? There is only an auditory/tactile input (contact), a unpleasant feeling (*vedanā*), and a mental reaction (*saṃskāra*). None of these components own a solid self. 2. *Deconstruct Dependent Origination (因缘空)*: Traffic is an interplay of weather, signals, urban density, and hundreds of human schedules intersecting. There is no central director (*无主*). 3. *Outcome*: The anger loses its hook. You do not force yourself to smile; rather, the dramatic storyline collapses because you see it has no permanent core.

Scenario 2: Scrolling Social Media & The Algorithmic Loop

- The Delusive Habit: You open an app, scrolling through highlights of peers buying homes, getting promotions, or looking vibrant. You feel an immediate wave of inadequacy, followed by a urge to post something that project an enviable image of yourself. - **Applying *Śūnyatā-samādhi***: 1. *Recognize Self-Emptiness (法性自空)*: The digital images on the screen are light waves; your reaction is an assemblage of mental recognition (*saṃjñā*) and habitual craving (*saṃskāra*). 2. *Avoid the Trap of the Painter (画师自惧)*: You realize that the "enviable self" or "loser self" are projections generated by your own mind, amplified by predictive algorithms designed to capture attention. You are frightened or envious of a phantom you helped construct. 3. *Outcome*: You put down the phone without feeling crushed or inflated. You see the feed for what it is: fleeting digital phenomena empty of an absolute self.

Scenario 3: Overtime, Workplace Feedback, and Identity

- The Delusive Habit: A project you worked on for weeks receives critical feedback from leadership. You feel crushed, thinking, *"My talent is unrecognized. I am a failure."* Or, conversely, when praised, you feel superior to your team. - **Applying *Śūnyatā-samādhi***: 1. *Practicing Non-Grasping Action (具足行空)*: You do your work with full dedication, but without forming a rigid conceptual identity (*不想*) as "the heroic creator." 2. *Emptiness of Results*: The project outcome is the result of market trends, team communication, individual skill, and timing. When criticism comes, you analyze the variables objectively without taking it as an existential strike against your self-worth. 3. *Outcome*: Burnout declines significantly because energy is spent executing tasks rather than defending a fragile ego-construct.

Scenario 4: Intimate Relationships and Parenting

- The Delusive Habit: Your partner or child behaves unpredictably or expresses anger. You lock into a defensive posture: *"How dare you treat me after everything I’ve done for you!"* - **Applying *Śūnyatā-samādhi***: 1. *The Bodhisattva's Equanimity (视如一子)*: Just as the sūtras describe a Bodhisattva helping beings without generating self-congratulatory pride or resentment, you support your family without converting love into a transaction. 2. *Seeing Through the Monster*: When your partner expresses anger, you recognize that their outburst is driven by exhaustion, fear, or past conditioning. You see the *causes* behind the emotion rather than labeling them a "toxic person." 3. *Outcome*: Like the forest that remains undisturbed whether trees grow or are cut down, your capacity to love becomes resilient, spacious, and unshakeable.


当代人为什么需要它 (Why Contemporary People Need It)

In contemporary society, we live under the relentless pressure of hyper-individualism, algorithmic optimization, and identity performance. Here is why *Śūnyatā-samādhi* provides an essential psychological and spiritual antidote:

1. Liberation from the "Self-As-A-Product" Paradigm

Modern culture compels individuals to brand themselves, optimize their habits, and curate an online persona. This creates an exhausting burden: the constant upkeep of a rigid identity. *Śūnyatā-samādhi* reminds us that the self is not a solid product to be engineered, but a fluid, open flow of conditions. When you realize that your identity is empty of a fixed essence, the pressure to "be somebody" dissolves.

2. Deconstruction of Algorithmic Traps

Artificial intelligence and feed algorithms are designed to target human psychological vulnerabilities—fear, outrage, vanity, and tribalism. These algorithms operate by feeding our mental constructs (*saṃjñā*). *Śūnyatā-samādhi* equips us with a perceptual filter: when an algorithm presents an outrage-inducing stimulus, the practitioner observes the sensation arise and pass without identifying with it, breaking the loop of digital manipulation.

3. Burnout Resistance Through "Action Without Grasping" (*具足行空*)

High-stress careers often cause burnout not from physical labor alone, but from the psychological weight of expectation, ownership, and fear of failure. The canonical principle of *Jùzú Xíng Kōng* (具足行空—acting fully while resting in emptiness) teaches us to engage deeply in our work while letting go of ego-driven demands for validation. Action becomes clean, efficient, and light.

4. Cognitive Science and its Boundaries

Contemporary neuroscience and cognitive science frequently echo Buddhist insights: the brain constructs a cohesive sense of "self" through neural networks (like the Default Mode Network), but no localized "self-entity" exists inside the brain.

However, a crucial distinction must be maintained: - Scientific Observation: Neuroscience describes *Śūnyatā-like* phenomena as functional brain mechanics—showing how self-referential thoughts decrease during deep focus or meditation. - The Limit of Science: Science treats this primarily as an objective, third-person neurological observation. - The Buddhist Path: *Śūnyatā-samādhi* is a lived, first-person contemplative transformation (*bhāvanā*) aimed at eradicating spiritual ignorance (*avidyā*) and moral/emotional afflictions (*kleśa*), ultimately leading to Parinirvāṇa. Science maps the engine; *Śūnyatā-samādhi* liberates the driver.


常见误读与澄清 (Common Misreadings and Clarifications)

Because the word "Emptiness" (空, *Kōng*) is easily misunderstood in translation and modern culture, several critical misconceptions must be clarified:

``` +-----------------------------------------------------------------------------------+ | MISCONCEPTIONS VS. CANONICAL TRUTH | +------------------------------------+----------------------------------------------+ | Misconception | Canonical Reality (Śūnyatā-samādhi) | +------------------------------------+----------------------------------------------+ | 1. "Emptiness means non-existence | Emptiness means lack of independent, fixed | | or nihilism (Nihilism)." | essence (*svabhāva*), NOT non-existence. | +------------------------------------+----------------------------------------------+ | 2. "Emptiness means emotional | True emptiness yields profound equanimity | | numbness or apathy." | and boundless, unattached compassion. | +------------------------------------+----------------------------------------------+ | 3. "Emptiness is a state of blank | It is active, lucid insight (*vipaśyanā*) | | trance with no thoughts." | into how phenomena dependently originate. | +------------------------------------+----------------------------------------------+ | 4. "I understand emptiness | Conceptual knowledge is the "medicine trapped| | intellectually, so I am free." | in the body." It must become direct insight. | +------------------------------------+----------------------------------------------+ ```

1. Misconception: "Emptiness Means Nihilism or Nothingness"

- Clarification: Emptiness (*śūnyatā*) does not mean that things do not exist or that life is meaningless. It means phenomena exist dependently (*pratītyasamutpāda*), free from an absolute, isolated essence. As the *Māhāratnakūṭa Sūtra* emphasizes, "It is not called empty because there are no people; rather, phenomena are empty in their own nature" (*非无人故名曰為空,但空自空*).

2. Misconception: "Cultivating Emptiness Makes You Cold and Uncaring"

- Clarification: People often confuse equanimity with emotional dissociation. Canonical texts explicitly refute this: Bodhisattvas cultivate *Śūnyatā-samādhi* specifically so they can serve sentient beings without suffering from personal burnout, resentment, or favoritism (*视众生如一子,无瞋无喜*). Emptiness empties out selfish grasping, leaving pure, boundless compassion.

3. Misconception: "Emptiness Is a Stupefied Trance Where Nothing Happens"

- Clarification: *Śūnyatā-samādhi* is not a state of sensory deprivation or mental blankness. In fact, classical texts list concrete, active meditation practices to enter it—such as the six-stage breathing method (*Ānāpānasmṛti*: counting, following, stopping, observing, returning, purifying) or investigating the components of body and mind. It is a state of vivid clarity (*vipaśyanā*) grounded in concentration (*samatha*).

4. Misconception: "Clinging to the Idea of Emptiness Is Enlightenment"

- Clarification: This is the exact trap of Emptiness-View (空见). The scriptures remind us of the painter terrified of his own drawing (*画师自惧*) and the medicine stuck in the body (*药不出体*). If you use the concept of "emptiness" to dismiss morality, dismiss other people's pain, or superiorly look down on others, you have turned the ultimate cure into a new spiritual disease. True *Śūnyatā-samādhi* burns away all views—including the dogmatic view of emptiness itself—like two wood sticks consumed by their own flame (*两木相磨,火出还烧*), leaving the mind utterly open, peaceful, and free.

Canonical EntryAI-generated

一、定义与核心要义

空三昧(śūnyatā-samādhi),又称空定,是佛教核心的禅定法门与解脱路径。它以观照诸法自性空、无我及我所为核心,是行者断除烦恼、证得圣果乃至成就大涅槃的重要功德。在经典中,空三昧不仅是消除业障、清净自心的修行阶段,更是菩萨在度化众生时保持平等心、不堕入执着的重要保障。

二、主要阐述

1. “空”的本质与观照对象

经典对“空”的本质进行了深刻剖析。在《大宝积经》中,强调“法性自空”,即诸法并非因有了“空”才变空,而是其本性自空,且“前際空、後際空、中際亦空”。在《大方等大集经》中,空三昧的观照对象被具体化为“七种空”:一是“阴空”,观五阴皆空,无我与我所;二是“界空与入空”,观十八界与十二入皆空;三是“谛空”,观四圣谛无得无舍;四是“因缘空”,观十二因缘无我我所;五是“性空”,观眼等诸法之性皆空;六是“法空与实空”,观一切法中无有觉观、我及我所。通过这些观照,行者得以“见诸法无命,观诸法无主”。而在《大般涅槃经》中,这种观照进一步延伸至“一切皆空”,不仅色、眼、识等是空,连六波罗蜜、如来乃至大般涅槃也“皆悉是空”,最终“见一切法性无所有”。

2. 修持方法与禅定次第

修习空三昧有多种具体的禅修路径。其一,可通过“阿那波那念”(入出息念)的数、随顺、止住、观相、转还、快净等六步修行,最终获得“净空三昧”。其二,通过修习不净观与白骨观,观察身骨碎末为尘、随风吹散,直至唯见虚空,亦能引导行者进入空三昧。其三,在日常行持中“具足行空”,即在修行布施、持戒等一切善法时,皆做到“不想”(不作概念性执着),甚至不希求入于圣慧、不想道心,在行持功德的同时不存执念。此外,若菩萨在梦中见如来而知有杂业障,亦应在安静之处“勤修空三昧”以净心。

3. 菩萨的悲愿与平等心

大乘佛教中的空三昧具有独特的悲愿特征。菩萨修持空三昧是“不舍众生”的,其目的是为了“调伏众生”,虽观生死过而不脱烦恼,深乐诸有以度化有情。同时,因“善能修习空三昧”,菩萨在度化众生时能视众生如一子,虽为众生断除烦恼,却不生“我为众生断烦恼”之念,对众生不产生瞋恨或喜悦,达到无瞋无喜的平等境界。

4. 警示与辩证:防范“空见”与见佛性

经典极力警示修行者不可执着于“空”而落入“空见”。《大宝积经》指出,“寧起我見積若須彌,非以空見起增上慢”,因为一切诸见皆可通过“空”来解脱,但若生起“空见”则无法除去。经中对此用了多个生动的比喻:如“药不出体”导致病重;“畏虚空”而欲舍离虚空;“画师自惧”亲手画的夜叉;以及“幻师自食”与“两木相磨”生火自焚,说明观空之“观亦空”。在辩证关系上,《大般涅槃经》指出,凡夫因“相似相续”而误认为不空,菩萨必须通过“修习空”才能“见诸法空”。同时,空三昧能“见不空法,能令空寂”,使菩萨虽见女人而不生女相、不生贪心,因此“不空作空”并非颠倒。更深一层,九地以下的菩萨因“见法有性”而不能见佛性,通过修习空三昧“不见法性”,从而得以“见佛性”。

三、不同部类与译本的表述差异

在不同部类的经典中,对于相关概念和术语的翻译与使用呈现出鲜明的时代与部派特征: 1. 五蕴与五阴:《大方等大集经》统一使用具有早期译经特征的“阴”或“五阴”来称呼“五蕴”(如“五阴担”、“阴空”、“色阴”)。 2. 处与入:《大方等大集经》使用“入”或“六入”来称呼“处”或“十二处”(如“入空”、“六入因缘”)。 3. 呼吸法门:《大方等大集经》保留了梵语译名“阿那波那”来论述呼吸法门与空三昧的关联。 4. 空三昧与空定:《大般涅槃经》在术语使用上,将“定相”称为“空三昧”,并频繁将“空定”与“空三昧”进行互换使用(如佛陀因“修空”而“见空寂悉无所有”,交替称为“修空定”与“修空三昧”)。

四、与相关概念的关系

1. 三解脱门:空三昧与无相三昧、无愿三昧并称为三解脱门,是通往涅槃和解脱的核心禅定。在《大般涅槃经》中,这三者分别对应“定相”(空三昧)、“慧相”(无愿三昧)与“捨相”(无相三昧),是菩萨修行知时非时的关键。 2. 意三昧与有为三昧:《大宝积经》中,与空三昧相类的还有“意三昧”(了知意界性空、无住无处所)和“有為三昧”(了知一切有为诸行性无积集、一切寂静)。 3. 真法界:经中指出,“真法界者,即空三昧无相无愿”。

五、代表性原文引用

1. 《大宝积经》:“寧起我見積若須彌,非以空見起增上慢。所以者何?一切諸見以空得脫,若起空見無能除者。” 2. 《大宝积经》:“非无人故名曰為空,但空自空……前際空、後際空、中際亦空。” 3. 《大方等大集经》:“真法界者,即空三昧无相无愿。” 4. 《大般涅槃经》:“一切诸法性本自空……修习空者,见诸法空。” 5. 《大般涅槃经》:“不见法性,见佛性。”

增壹阿含經T0125 · 阿含部

《增壹阿含經》對「空三昧」的論述,核心要點如下:

一、定義與本質:佛陀於舍衛國祇樹給孤獨園告諸比丘:「空三昧者,所謂空者,觀一切諸法,皆悉空虛」,明確以「觀一切諸法皆空虛」為此三昧之內涵。佛並教誡比丘當求此三三昧(空、無願、無想),若不得者,久在生死,不能自覺寤。

二、最為第一之三昧:佛稱空三昧「最為第一」,又名「王三昧」,於諸三昧中為最尊。舍利弗即以常遊空三昧而蒙佛讚歎。

三、行者所得之觀照:修空三昧者能「計無吾我、人、壽命,亦不見有眾生;亦復不見諸行本末」,已不見,亦不造行;已無行,更不受有;已無受有,不復受苦樂之報。

四、為成佛之根本:佛自述未成佛道時曾作是念:「無有空三昧者,便流浪生死,不得至竟解脫。」得空三昧則進得無願三昧,得無願三昧則不求死此生彼、都無想念時,彼行者復有無想三昧可得娛樂;三者展轉相生,皆以空三昧為根本。佛因得空三昧,七日七夜觀視道樹目未曾眴,成就阿耨多羅三藐三菩提。

五、與他三昧之關係:空、無願、無想合稱「三三昧」,三者非孤立而為次第開展——以空三昧為先,依此得無願,更進得無想。

六、行此三昧之人:在家弟子中,毘讎先優婆斯行空三昧,與行無想三昧之優那陀優婆斯、行無願三昧之無垢優婆斯並列而舉;聲聞弟子中,舍利弗恒遊空三昧,並多遊空三昧、金剛三昧二處。

七、術語形式:本經主要使用「空三昧」一詞,亦見異稱「虛空三昧」,二者所指為同一概念,未見其他譯名。

摩訶般若波羅蜜經T0223 · 般若部

《摩訶般若波羅蜜經》(後秦鳩摩羅什譯)論「空三昧」,主要以菩薩行般若波羅蜜之立場立說,將其與「無相三昧」、「無作三昧」並列為三解脫門。

一、三昧的並列與勸修:經中常以「空、無相、無作三昧」三者並舉,菩薩應「自修空三昧,無相、無作三昧,亦教人修……讚歎修……歡喜讚歎修……者」,與四念處、八聖道分、八背捨、九次第定同列為菩薩所應自行教他之德目。

二、學空三昧與入空三昧之分:須菩提問「云何學空三昧?云何入空三昧?」佛告菩薩行般若波羅蜜時,應觀色空、受想行識空、十二入空、十八界空,乃至欲、色、無色界空,作是觀時不令心亂;若心不亂則不見是法、不作證,以菩薩「善學自相空故」,「證法、證者皆不可見」。

三、學時非證時之要:本經反覆強調菩薩「先作是願:我今不應空法作證,我今學時非是證時」,菩薩「住是空中」修空三昧、無相三昧、無作三昧時,皆「非是證時」;以不專攝心繫在緣中故,於阿耨多羅三藐三菩提不退,亦不取漏盡之證。

四、具足修空三昧:菩薩以方便力行般若波羅蜜,未具足佛十力乃至十八不共法,不於實際作證,爾時「具足修空三昧」。

五、修空三昧亦當「壞」——以般若銷盡一切:本經以「修……壞,是修般若波羅蜜」之特殊句式遍列諸法門,結云「修空三昧、無相三昧、無作三昧壞,是修般若波羅蜜」,意謂連空三昧本身亦須以般若智觀其空寂而銷盡之。

本經用詞特點:以「空三昧」與「無相、無作三昧」固定搭配,列為三解脫門;五蘊作「五蔭」(如「法名五蔭,五蔭空」);十八空則詳列散空、性空、自相空、諸法空、不可得空、無法空、有法空、無法有法空,乃至法法相空、無法無法相空、自法自法相空、他法他法相空等之定義。

整體而言,本經以「觀空不證空、空三昧亦須以般若銷壞」為論述空三昧之核心面向,凸顯菩薩不住空定、不執空三昧之般若精神。

大寶積經T0310 · 寶積部

《大寶積經》論述「空三昧」之核心表述,集中於兩方面:一是住於此三昧所成就的觀察智慧,二是以此為修行的具體法門。

一、術語形式 本經以「空三昧」與「空三摩地」二種譯名並用。前者用於記載菩薩往昔修行之敘述,後者則用於描述住此定者所起的覺察作用。

二、住空三摩地所成就的觀察力 經云:「由住彼空三摩地覺,能善觀察一切諸法,隨得無相方便善巧,而於一切無所執著。」 菩薩安住於空三摩地之覺,即能善觀一切法相,得無相之善巧方便,對一切法無所執著。此中「無相方便善巧」乃空三昧所引生的特殊方便。

三、由空三昧引生的悲智雙運 同段經文續言:住空三摩地覺者能了知三界有為之法皆是過患而求出離,速得寂靜極寂靜界及勝解脫勝出離界;然於彼識不住不著,觀察生滅積集散壞,並「於諸有情起大慈悲,為成熟故生出離覺,以覺理趣隨宜方便,能隨順入最勝智慧」。可見本經將空三昧置於「智觀空—悲濟有」的結構中:先以空慧照破執著,繼而起大慈悲成熟眾生,此為此經論述空三昧的獨特側面。

四、空三昧與菩薩地及夢相的關聯 經以夢境為喻判別菩薩修行階位時云:「菩薩夢中見一如來,應靜處勤修空三昧。此菩薩是八地雜業障,應勤修淨心。」 此處指出:(一)見如來夢相為修空三昧之緣起;(二)此菩薩居八地而有業障夾雜;(三)修空三昧之處應為「靜處」;(四)配合「勤修淨心」以對治業障。此以夢相占位方式呈現空三昧於十地修行中之位置,為本經特有之表述。

五、菩薩往昔於諸佛所修空三昧 經記無垢施菩薩本行:「曾於六十億佛所修空三昧,於八十億佛所修無生法忍,於三十億佛所問甚深法。」 此以「修空三昧」為菩薩長期累積之勝行,與「修無生法忍」「問甚深法」並列為三大精進之行;本經復明受持此經之功德勝過以恒河沙數佛剎珍寶布施,由此襯顯空三昧作為菩薩菩提行法之深重分量。

小結:本經論空三昧,兼攝定慧雙運、悲智並運、十地階位及菩薩往昔勝行數端。術語以「空三昧」「空三摩地」並出,未見其他特殊異譯。
