What This Concept Is Saying

In Buddhist cosmology and meditative psychology, the Nine Abodes of Beings (*Navasattvāvāsa* / 九眾生居) delineate the ultimate geographic, physical, and mental frontiers of conditioned existence (*saṃsāra*). One-sentence summary: *The Nine Abodes of Beings refer to the nine realms and states within the Three Realms (Desire, Form, and Formless) where sentient beings reside and take refuge; they represent the complete outer boundaries of samsaric existence that a practitioner must clearly observe and ultimately transcend.*

To understand this concept, we must look at how early Buddhism maps reality. Early texts like the *Dīrgha Āgama* (*Long Discourses* / 《長阿含經》) categorize these nine realms primarily by examining the interaction between a being's physical form (*kāya* / 身) and their cognitive/perceptual consciousness (*saṃjñā* / 想, translated in earlier Chinese texts as "thought" or "perception"), alongside the refined states of Formless absorption (*ārūpya-samāpatti*).

Here are the nine exact divisions defined in classical canonical texts:

1. The First Abode (Different Bodies, Different Perceptions / 若干種身,若干種想): Beings who possess diverse physical forms and diverse modes of perception. This is represented by humans, animals, ghosts, hell-dwellers, and various lower gods (*devas*) of the Desire Realm (*kāma-dhātu*). 2. The Second Abode (Different Bodies, Single Perception / 若干種身而一想): Beings who possess diverse physical forms but share a single, unified mode of perception. This refers specifically to the *Brahma* deities at the moment of initial manifestation/rebirth (e.g., *Brahma-pāriṣadjā* or early *Abhāsvara* gods). 3. The Third Abode (Single Body, Different Perceptions / 一身若干種想): Beings who share an identical, uniform luminous physical form but maintain diverse individual perceptions. This is represented by the Gods of Ultimate Light (*Ābhāsvara* / 光音天) in the Form Realm (*rūpa-dhātu*). 4. The Fourth Abode (Single Body, Single Perception / 一身一想): Beings who possess both a uniform physical body and a completely unified, harmonious perception. This is represented by the Gods of Pervasive Purity (*Subhakṛtsna* / 遍淨天) in the Form Realm. 5. The Fifth Abode (No Perception, No Sensation / 無想無所覺知): Beings who have physical form but have temporarily suspended all mental activity and perception. This is the Realm of Non-Perceptive Beings (*Asaṃjñi-sattva* / 無想天) within the Form Realm. 6. The Sixth Abode (Dwelling in Infinite Space / 空處住): The first realm of the Formless Realm (*ārūpya-dhātu*), where all physical form is surpassed, and consciousness rests entirely in the perception of infinite space (*Ākāśānantyāyatana* / 空處智天). 7. The Seventh Abode (Dwelling in Infinite Consciousness / 識處住): The second Formless realm, where consciousness turns inward upon itself, dwelling in boundless awareness (*Vijñānānantyāyatana* / 識處智天). 8. The Eighth Abode (Dwelling in Nothingness / 不用處住): The third Formless realm, where consciousness transcends both space and awareness to rest in absolute nothingness (*Ākiṃcanyāyatana* / 不用處智天, classical translation: "the realm of non-possession/nothingness"). 9. The Ninth Abode (Dwelling in Neither-Perception-Nor-Non-Perception / 住有想無想處): The absolute apex of samsaric existence (*Bhavāgra*), where perception is so subtilized that it cannot be said to exist, yet subtle mental traces remain (*Naiva-saṃjñā-nāsaṃjñāyatana* / 有想無想智天, commonly translated as 非想非非想處).

``` ======================================================================================== THE NINE ABODES OF BEINGS (九眾生居) ======================================================================================== [ FORMLESS REALM ] 9th Abode: Neither-Perception-Nor-Non-Perception (有想無想處) <-- Apex of Existence (Bhavāgra) 8th Abode: Realm of Nothingness (不用處 / 無所有處) 7th Abode: Realm of Infinite Consciousness (識處) 6th Abode: Realm of Infinite Space (空處) ---------------------------------------------------------------------------------------- [ FORM REALM ] 5th Abode: Non-Perceptive Beings (無想天) [Form: Yes | Perception: Suspended] 4th Abode: Pervasive Purity (遍淨天) [Form: Single | Perception: Single] 3rd Abode: Ultimate Light (光音天) [Form: Single | Perception: Different] 2nd Abode: Initial Brahma Rebirth (梵光音天初生) [Form: Different | Perception: Single] ---------------------------------------------------------------------------------------- [ DESIRE REALM ] 1st Abode: Humans, Lower Devas, Animals, etc. (天及人等) [Form: Different | Perception: Different] ======================================================================================== ```

In early texts like the *Samyukta Āgama* (*Connected Discourses* / 《雜阿含經》), the Nine Abodes are grouped within a sequential numerical teaching (from one to ten factors), closely linked with the Five Aggregates (*pañca-skandha*, translated in early texts as *五受陰*) and the Seven Stations of Consciousness (*sapta-vijñāna-sthiti* / 七識住).

While cosmology maps *where* these places are, the Buddha's core pragmatic intention was not geography—it was liberation. The text explicitly declares: "Up to this is called the boundary of beings, the world of beings" (齊此名眾生邊際、眾生世界). No matter how serene, long-lived, or spiritually sublime a state within these nine abodes may be, it remains bound to the wheel of impermanence (*anicca*), change (*vipariṇāma*), and suffering (*dukkha*).

To achieve Nirvana—to exhaust all mental defilements (*kṣaya-āsrava* / 盡諸漏)—the practitioner must cultivate five modes of wisdom observation (正觀) toward these nine abodes: 1. Observing impermanence (觀無常) 2. Observing changeability (觀變易) 3. Observing detachment/fading of desire (觀離欲) 4. Observing cessation (觀滅) 5. Observing relinquishment/renunciation (觀捨離)

By seeing that even the highest, most exquisite spiritual realm (the 9th Abode) is still a prison cell, one generates true revulsion, dispassion, and turning-away (*nibbida* / 厭離與背捨), finally breaking out of the bounds of existence altogether.


A Walk Through Contemporary Life

To prevent these nine abodes from remaining mere ancient cosmic taxonomy, let us trace how these nine mental and physical modes manifest in modern life. The Nine Abodes do not merely describe physical heavenly realms after death; they describe the *entire bandwidth of psychological refuge* that human minds seek every single day.

``` [ MODERN PSYCHOLOGICAL MAPPING OF THE NINE ABODES ]

Subtle Ego / Deep Mind-Flow --------> 9. Neither-Perception-Nor-Non-Perception Pure Objective Void / Minimalism ----> 8. Nothingness / Non-Possession Pure Metacognition / Big Data ------> 7. Infinite Consciousness Boundless Expansion / Open Sky ------> 6. Infinite Space Total Burnout / Emotional Numbness --> 5. Non-Perception (Suspended State) Absolute Team Synergy / Monochronic -> 4. Single Body, Single Perception Individual Freedom / Shared Culture -> 3. Single Body, Different Perceptions Corporate Hierarchies / Ideology ---> 2. Different Bodies, Single Perception Daily Commute / Social Media Feeds --> 1. Different Bodies, Different Perceptions ```

1. The 1st Abode (Different Bodies, Different Perceptions)

* Modern Scene: A crowded subway car during rush hour, or your algorithmically driven social media feed. * Psychological Reality: Every individual has a different body (height, clothes, sensory stress) and completely different thoughts (one person worries about rent, another listens to rock music, another reads news, another boils with frustration). * The Trap: Chaos, friction, and sensory overload. This is typical Desire Realm existence, where sensory craving (*kāma*) drives relentless distraction.

2. The 2nd Abode (Different Bodies, Single Perception)

* Modern Scene: Employees in a strict corporate hierarchy or followers attending a massive, charismatic rally. * Psychological Reality: Everyone maintains a distinct physical body, but their minds are swept into a *single, unified narrative*—the founder’s vision, the company slogan, or a shared political ideology. * The Trap: Mistaking external ideological unity or groupthink for genuine spiritual peace.

3. The 3rd Abode (Single Body, Different Perceptions)

* Modern Scene: Digital avatars in a virtual reality space, or remote workers behind uniform corporate laptop screens. * Psychological Reality: Physically/structurally, everyone is reduced to an identical standard medium ("single body"—uniform luminous interface), yet inwardly, their private thoughts, creative drives, and personal inner worlds diverge sharply ("different perceptions"). * The Trap: Being tricked by the sleek, uniform aesthetic of digital space while remaining internally fragmented and restless.

4. The 4th Abode (Single Body, Single Perception)

* Modern Scene: A world-class symphony orchestra in full flow, or a highly disciplined meditation retreat where hundreds sit motionless in identical robes, breathing as one. * Psychological Reality: Physical form is stabilized into complete stillness, and sensory perception is synchronized into profound harmony. * The Trap: Confusing deep psychological harmony, emotional resonance, or blissful group synergy with ultimate liberation.

5. The 5th Abode (No Perception, No Sensation)

* Modern Scene: Seeking escape through intense burnout recovery, floatation tanks, sensory deprivation, or heavy sedatives—wishing to "just turn off my brain." * Psychological Reality: Suppressing all conscious thought and emotional awareness. The body remains, but awareness is completely blanked out. * Common Mismapping: People often mistake a totally blank, thoughtless state or deep un-cathected stupor for "Nirvana" or "emptiness." In reality, it is merely the temporary suppression of mind (*asaṃjñi*), which inevitably ends, returning the soul right back into suffering when thoughts re-emerge.

6. The 6th Abode (Dwelling in Infinite Space)

* Modern Scene: Looking up at the night sky or standing before a vast ocean, experiencing the psychological release of feeling "boundless space." * Psychological Reality: The mind intentionally drops awareness of physical form and sensory clutter, expanding its scope to imagine endless, open spatial vacuum.

7. The 7th Abode (Dwelling in Infinite Consciousness)

* Modern Scene: A data scientist or philosopher realizing the infinite recursive capacity of awareness—realizing that space itself is known only through *consciousness*, turning awareness back onto the observer itself. * Psychological Reality: Pure metacognition. The experience of "I am the boundless observer of all things."

8. The 8th Abode (Dwelling in Nothingness)

* Modern Scene: Radical minimalism, deep trance states, or aesthetic voidness—where the mind deliberately casts off all objects, spatial references, and consciousness markers, declaring: "There is nothing whatsoever." * Psychological Reality: Reaching a subtle state where no mental object is grasped or recognized.

9. The 9th Abode (Dwelling in Neither-Perception-Nor-Non-Perception)

* Modern Scene: The threshold between deep dreamless sleep and subtle waking, or the absolute peak of non-dual meditative absorption (*samādhi*). * Psychological Reality: Perception is so subtle that it can no longer be categorized as conscious thought, yet it has not broken the subtle root of ego-clinging (*asmi-māna*). It feels like merging with the cosmic source. * The Ultimate Trap: Believing you have achieved ultimate Enlightenment, Moksha, or union with the Divine, when in reality you are merely residing in the 9th Abode—the highest attic of samsaric existence.


Why Contemporary People Need This Concept

We live in an age obsessed with optimization, immersive experiences, and spiritual bypassing. Modern culture constantly sells us higher "abodes" as ultimate remedies for human suffering:

1. De-mystifying Meditative and Psychedelic States: Many modern seekers undergo profound meditative experiences, flow states, or high-dose psychedelic trips where physical bodily boundaries vanish (6th & 7th Abodes) or where all mental objects dissolve into absolute voidness (8th Abode). Without the analytical framework of the Nine Abodes, people frequently mistake these temporary, conditioned states of deep absorption (*jhāna*) for full Enlightenment. The Nine Abodes serve as a crucial diagnostic tool: *If there is still a state being inhabited, it is still within Samsara.*

2. Dismantling the Illusion of "Mindless Peace": In an era of cognitive burnout, many people crave the 5th Abode—the Realm of Non-Perception. They try to numb their feelings, stop all thoughts, or chase blank states. Early Buddhism reminds us that "having no thoughts" is merely a temporary freezing of the mind (like a frozen pond in winter); when the weather warms, the seeds of craving and anger melt and resume sprouting.

3. Understanding the Limits of Tech-Utopianism and AI: Whether it is uploading consciousness to digital servers or creating interconnected global collective intelligence (higher forms of 2nd, 3rd, and 4th Abodes), the Nine Abodes teach us that even if humanity achieves transhumanist longevity or collective digital harmony, it will still remain within the "boundary of beings" (眾生邊際). Freedom is not found by upgrading the cage from iron (Desire Realm) to gold (Form Realm) to invisible glass (Formless Realm)—it is found by stepping outside the cage entirely.


Common Misreadings and Clarifications

Misreading 1: Treating the Nine Abodes as literal "physical planets or alien dimensions" only.

* Clarification: While ancient cosmology describes these as cosmological realms (*loka*), early Buddhist psychology emphasizes that realms of rebirth are fundamentally expressions of mental states (*citta*). The Nine Abodes map the entire spectrum of how consciousness binds itself to existence through form (*kāya*) and perception (*saṃjñā*).

Misreading 2: Confusing the 5th Abode (Non-Perception / 無想天) with Nirvana.

* Clarification: The 5th Abode is a state of severe mental suppression where physical form remains but subtle mental activity is suspended due to mistaken meditative practice. Nirvana, by contrast, is not mental deadness or mindless blankness; it is the active, clear, unshakeable wisdom (*prajñā*) that beholds reality as it is, free from greed, hatred, and delusion.

Misreading 3: Believing that higher Formless states (6th to 9th Abodes) are inherently "Buddhist解脫 (liberation)."

* Clarification: Before his enlightenment, Siddhartha Gautama studied under the great ascetics Ārāḍa Kālāma and Udraka Rāmaputra, mastering the 8th Abode (Nothingness) and the 9th Abode (Neither-Perception-Nor-Non-Perception). He famously rejected these attainments because, once the karmic momentum of those meditative states wore off, one eventually falls back into lower realms. Achieving the 9th Abode is not liberation; liberation requires applying the Five Wisdom Observations (observing impermanence, change, dispassion, cessation, and relinquishment) *even to these celestial states* to break the final subtle roots of existence.

Misreading 4: Conflating "The Nine Abodes of Beings" with "The Seven Stations of Consciousness" (*sapta-vijñāna-sthiti* / 七識住).

* Clarification: Though closely related in the *Samyukta Āgama*, they are not identical. The "Seven Stations of Consciousness" excludes the 5th Abode (Non-Perception, because consciousness is suspended there) and the 9th Abode (Neither-Perception-Nor-Non-Perception, because consciousness is too subtle to serve as a stable "station"). The Nine Abodes is a more exhaustive list that covers *all* possible refuges of beings across the Three Realms—including the extreme edge cases where consciousness is dormant or nearly extinguished.


Conclusion: The Final Step Outside

The Nine Abodes of Beings present a breathtaking map of reality. It shows us that from the lowest earth-bound struggle of human daily life, up through magnificent realms of light, resonance, infinite space, pure consciousness, and transcendent voidness—all of it is a continuous continuum of conditioned existence.

The goal of early Buddhist practice is not to climb to the 9th floor of this cosmic skyscraper and stay there forever. The goal is to look out from the highest window, see clearly that even this sublime tower is built on the sands of impermanence, cultivate profound dispassion (*nibbida*), and step out into the unconditioned freedom of Nirvana.

一、 定义与核心要义

「九众生居」(navasattvāvāsa),又称「九正法」或「九觉法」,是指三界之中一切众生所居住、依止的九种处所。这一概念在阿含部经典中具有双重意义:一方面,它从宇宙论的角度,依众生的身体形态(身)与心识知觉(想)的异同,以及无色界的禅定状态,系统地划分了众生在生死轮回中的所有存在状态与界限;另一方面,它在实践哲学中被视为修行者必须进行正观、生起厌离并最终予以超越的解脱对象。

二、 主要阐述

根据《长阿含经》与《杂阿含经》的论述,九众生居的具体分类、宇宙边际以及修行实践路径如下:

1. 九众生居的具体分类

在《长阿含经》中,如来详细阐述了九众生居的具体内容,其分类主要依据众生「身」与「想」的异同,以及无色界的禅定状态: * 第一众生居:众生具有「若干种身,若干种想」,以「天及人」为代表。 * 第二众生居:众生具有「若干种身而一想者」,指「梵光音天最初生时」的众生。 * 第三众生居:众生为「一身若干种想」,以「光音天」为代表。 * 第四众生居:众生为「一身一想」,以「遍净天」为代表。 * 第五众生居:众生「无想无所觉知」,以「无想天」为代表。 * 第六众生居:众生「空处住」。 * 第七众生居:众生「识处住」。 * 第八众生居:众生「不用处住」。 * 第九众生居:众生「住有想无想处」。

2. 宇宙论背景与界限

《长阿含经》进一步指出,从欲界、色界诸天,一直到无色界的最高处,这一范围「齐此名众生边际、众生世界」。这是一切众生经历生、老、病、死、受阴、受有的极限,众生无法超越这个范围。这说明「九众生居」完整覆盖了众生在三界中生死轮回、受阴受有的所有可能居所。

3. 核心修行实践与解脱路径

与《长阿含经》侧重宇宙论结构不同,《杂阿含经》并未详细展开九个处所的具体名称,而是将「九众生居」作为一个整体的修行观察对象,强调对其进行正观、厌离以达到解脱的实践路径: * 生正厌离与背舍:修行者若能对包括「九众生居」在内的十种法,生起正确的厌离、不乐与背舍,便能导向最终的解脱。如经中所言,若能于此「生厌、不乐、背舍」,即可「得尽诸漏」,进而「究竟苦边,解脱于苦」。 * 修持五种智慧观察(正观):修行者需要对「九众生居」等法进行五种深度的智慧观察,即观察无常、观察变易、观察离欲、观察灭、观察舍离。透过这五种正观,修行者同样能够断尽烦恼,实现「得尽诸漏」。

三、 不同部类与译本的表述差异

在不同的经典与译本中,关于九众生居及相关概念的术语表述存在明显的差异: * 无色界后两处的称呼:对于无色界的后两处,《长阿含经》使用「不用处」(而非其他经典常见的「无所有处」)与「有想无想处」(而非「非想非非想处」)。 * 无色界四天的称呼:在论及宇宙界限时,《长阿含经》将无色界四天称为「空处智天、识处智天、无所有处智天、有想无想处智天」,或简称为「空智天、识智天、无所有智天、有想无想智天」。 * 「五蕴」的译名:在论及众生受生与界限时,《长阿含经》与《杂阿含经》均使用了较为古老的译语。例如《长阿含经》称之为「受阴」或「五受阴」;《杂阿含经》在列举一至十法时,亦将「五法」译为「五受阴」,而非现代通行的「五蕴」或「五取蕴」。 * 「七识住」的译名:《杂阿含经》在法数序列中,将「七法」明确译为「七识住」,与「九众生居」并列。

四、 与相关概念的关系

* 与「五受阴」、「七识住」的关系:在《杂阿含经》中,「九众生居」被置于从「一法」到「十法」的系统性法数框架之中。它与「五受阴」(五法)、「七识住」(七法)等核心教法并列,共同构成了修行者在迈向解脱过程中必须正观、厌离的生存范畴。 * 与「众生边际」的关系:九众生居与「众生边际、众生世界」直接等同。它完整覆盖了众生在三界中生死轮回、受阴受有的所有可能居所。从最基层的欲界人天,到色界、无色界的最高禅定状态,皆被囊括在九众生居之内。修行者若不能对这九种居所生起「背舍」与「正厌离」,就无法超越「众生世界」的限制,无法脱离生老病死的循环。

五、 代表性原文引用

* 《长阿含经》: > 「復有九法,謂九眾生居。一者眾生若干種身、若干種想,天及人是。二者眾生若干種身而一想者,梵光音天最初生時是。三者眾生一身若干種想,光音天是。四者眾生一身一想,遍淨天是。五者眾生無想無所覺知,無想天是。六者眾生空處住。七者眾生識處住。八者眾生不用處住。九者眾生住有想無想處。」 * 《长阿含经》: > 「齊此名眾生邊際、眾生世界,齊此有生、有老、有死、有受陰、有受有,謂空處智天、識處智天、無所有處智天、有想無想處智天。」 * 《杂阿含经》: > 「爾時,世尊告諸比丘:『有十法。何等為十?……五法,謂五受陰;……七法,謂七識住;……九法,謂九眾生居……若比丘於此十法生厭、不樂、背舍,得盡諸漏。』」 * 《杂阿含经》: > 「若比丘於此十法觀察無常、觀察變易、觀察離欲、觀察滅、觀察舍離。於此十法觀察無常、變易、離欲、滅、舍離已,得盡諸漏。」

長阿含經T0001 · 阿含部

《長阿含經》以「九眾生居」一詞闡述眾生依身心差別而安住的九種處所。此概念在該經中以兩種脈絡呈現:一是置於「九正法」之內,二是歸入「九覺法」之列,兩處所列名目相同。

九眾生居的分類架構以「身」與「想」兩項為基準:初四種依身想的組合差別而立,第五種為想之全無而無所覺知,後四種則依無色界次第而定。具體而言:一者若干種身、若干種想,天及人是此初居;二者若干種身而一想,梵光音天最初生時屬此;三者一身若干種想,光音天是此居;四者一身一想,遍淨天是此居;五者無想無所覺知,無想天是此居;六者空處住;七者識處住;八者不用處住;九者有想無想處住。

經文在術語上有幾處值得留意:第四居「一身一想」對應「遍淨天」;第五居名「無想天」直承其「無想無所覺知」之義;第三居「光音天」與第二居「梵光音天」分別標明。在無色界四處之中,第八居之名該經以「不用處」一詞標出,此為本經用詞上一項值得記錄的特徵。

在結構安排上,本經將九眾生居並列於八解脫、八聖道等修行法門之後,作為如來所說正法之一部分,需由諸比丘共同「撰集,以防諍訟,使梵行久立」。另一處則將其納入「九覺法」之內,與「九喜本」「九愛本」等法數並列,呈現該經以法數方式編整教法的特色。

從內容看,該經對九眾生居的論述採取簡列方式,僅以身想之別標示每一居之特徵,並未對每一居的業因、果報或修證關聯作進一步闡述。其重心在於作為如來正法法數之一,與「九愛本」「九盡」等其他法數共同編入「九覺法」乃至「九正法」的體系之中。

雜阿含經T0099 · 阿含部

本經中「九眾生居」一詞出現於三段結構高度相近的經文,皆為佛住王舍城迦蘭陀竹園時之開示(、、)。

一、核心表述:作為「九法」名目之一

三段經文皆以同一數列(從一至十)排列諸法,將「九眾生居」置於「九法」之位:「一法,謂一切眾生由食而存;二法,名及色;三法,三受;四法,四食;五法,五受陰;六法,六內外入處;七法,七識住;八法,世八法;九法,九眾生居;十法,十業跡。」(、、)本經對「九眾生居」本身並無內容界定,亦未列舉九者為何,僅以名數形式將其與其他九項並列。

二、三段所示修行側面的差異

三段經文雖列同一數列,所授修行要點卻各有不同:

(一) 開示:於此十法「生厭、不樂、背捨」,得「盡諸漏」。 (二) 開示:於此十法「生正厭離、不樂、背捨」,達「究竟苦邊,解脫於苦」。 (三) 開示:於此十法「正觀無常、觀察變易、觀察離欲、觀察滅、觀察捨離」,得「盡諸漏」。

可見本經以「厭、不樂、背捨」、「正厭離、不樂、背捨」、「正觀無常等五觀」三種側面,教人對治包括九眾生居在內之十法。三段之果證亦分作兩種表述:「盡諸漏」(、)與「究竟苦邊,解脫於苦」()。

三、本經所用術語形式

本經一律稱「九眾生居」,未見其他異稱出現於此三段。同數列中亦呈現若干本經特有的用詞:五法稱「五受陰」(而非「五蘊」或「五陰」)、七法稱「七識住」(而非常見之「七識處」)、六法則作「六內外入處」(兼攝內外)。這些用詞形式為本經此三段之特徵。

四、小結

本經三段對「九眾生居」之論述,僅止於將其列為「九法」之名目,並未具體展開九者之內容;經文重心在於透過厭離背捨或正觀無常、變易、離欲、滅、捨離等修法,於包括九眾生居在內之十法上斷除諸漏,或究竟苦邊、得解脫於苦。

增壹阿含經T0125 · 阿含部

九眾生居處,《增壹阿含經》於三處明說此概念。

一、首段詳列九處

經由世尊告諸比丘「有九眾生居處,是眾生所居之處」,隨列九處:(1) 若干種身、若干種想——天及人;(2) 若干種身、一想——梵迦夷天最初出現;(3) 一身、若干想——光音天;(4) 一身、一想——遍淨天;(5) 無量空——空處天;(6) 無量識——識處天;(7) 不用處——不用處天;(8) 有想無想——有想無想處天。經末結云「諸所生之處名為九也」,並誡比丘「當求方便,離此九處」。

二、以想念差別釋九處安立之因

此段由釋提桓因問「天及人民有何想念」而起,世尊答以「世間流浪,其性不同,所趣各異,想念非一」,並舉無常計常、無樂計樂、無我有我、不淨有淨,乃至正路有邪路、惡有福、福有惡等八種顛倒想。世尊明示:「若當眾生盡同一想,無若干想者,九眾生居處,則不可知,亦難分別九眾生居,神識所止亦復難明。」正以眾生想念各異,故「知有九眾生居處、九神所止處,知有八大地獄、三惡道,至三十三天」。此處將「九神所止處」與「九眾生居處」並稱,凸顯「神識所止」之義。

三、數論架構中之九論、九義、九演

本經將九眾生居處置於「七論、八論、九論」之數法演說中,與「七神識止處」「世間八法」並列。世尊云「比丘平等厭患,平等解脫,平等分別其義,平等盡於苦際」,意即藉九處之說,令比丘於中平等厭離、解脫。所列九處名稱與首段大體一致,唯用語微異,如第七處作「無所有處無量」之說。

四、本經術語與行文特點

1. 主稱「九眾生居處」,亦用「九眾生居」「九神所止處」等異名;至於七處則稱「七神識止處」「七神止處」,「神識止處」與「眾生居處」二名並行。 2. 經文三次列舉皆僅出八項而標為「九」,此乃本經文本之特殊現象。 3. 三處所列八項之描述用語微有出入:首段光音天作「一身若干想」、遍淨天作「一身一想」;第三處則作「一想一身」(光音)與「一身若干想」(遍淨);且第三處首項僅云「若干種身」而略去「若干種想」,可見版本流傳中的小差異。 4. 本經特以「想念各異」為九處安立之根本因緣,並連結八大地獄、三惡道、三十三天之輪迴圖像,而非僅作純粹禪觀階梯。
