In the term 天住 (divya-vihāra, "divine abode"), the "abiding" (住) does not mean residing in some mystical location, but the state in which the mind takes its dwelling. The minds of ordinary people constantly dwell in pursuit, aversion, anxiety, and distraction; what is called the divine abode is taking sublime meditative practices—such as 安那般那念 (ānāpāna-smṛti, mindfulness of breathing) and 静虑 (dhyāna, meditative absorption)—as one's dwelling. Such cultivation can immediately become a clear and stable "现法乐住" (dṛṣṭa-dharma-sukha-vihāra, "abiding in ease in the present life"). If it still falls within the scope of 有漏 (sāsrava, "with outflows") karmic fruition, it may also become the cause for experiencing corresponding celestial rebirths.

Therefore, 天住 must be understood on at least three levels:

First, it is the meditative practice presently cultivated and abided in. The *Saṃyuktāgama* (《杂阿含经》) says that if one were to correctly explain 圣住 (ārya-vihāra, noble abode), 天住, 梵住 (brahma-vihāra, Brahmā abode), 学住 (śaikṣa-vihāra, trainee's abode), 无学住 (aśaikṣa-vihāra, adept's abode), and 如来住 (tathāgata-vihāra, Tathāgata's abode), one could call it "安那般那念"—mindfulness of breathing. 安那般那念 means the recollection of inhalation and exhalation: knowing truly the long and short of the in-breath and out-breath, knowing the entire bodily formation (身行, kāya-saṃskāra) connected with breathing, and gradually causing the bodily formation to become still. It is not simply "paying attention to the breath in order to relax"; rather, through sustained, true awareness, the coarse and scattered movements gradually become calm, entering a more subtle abiding. The sūtra calls the earlier stage "麁思惟住" (dwelling in coarse reflection), and after the coarse signs have ceased, one "更入微细思惟,多住而住" (enters further into subtle reflection, dwelling therein repeatedly). The point is not to manufacture a special feeling, but that the mind is no longer continuously dragged away by coarse grasping.

Second, it is meditative absorption itself. The *Yogācārabhūmi-śāstra* (《瑜伽师地论》) states directly: "此中静虑说名天住。" *("Here, dhyāna is called the divine abode.")* Dhyāna is not concentration in the ordinary sense, still less daydreaming, trance, or emotional numbness; it is a superior samādhi formed through training. The classical system unfolds its levels through the four dhyānas (四静虑) and four formless attainments (四无色定, catur-ārūpya-samāpatti). The *Saṃyuktāgama* particularly describes the fourth dhyāna, abided in fully, as: "离苦息乐,前忧喜已灭,不苦不乐舍,净念一心。" *("Leaving behind pain, stilling joy; earlier grief and delight have ceased; in neither pain nor pleasure, equanimous; with pure mindfulness, one-pointed.")* This does not mean the practitioner has lost the capacity for feeling; rather, pain, pleasure, and the earlier grief and joy have come to rest, and the mind dwells in equanimity (舍, upekṣā) that is neither painful nor pleasant, with mindfulness pure and unified. The "equanimity" here is not apathy, but a balance no longer pulled by pleasure and pain.

The cultivation of the four dhyānas has corresponding fruits according to the lower, middle, and superior grades. The correlations listed in the *Yogācārabhūmi-śāstra* are: the first dhyāna corresponds to 梵众天 (brahma-pāriṣadya, "Retinue of Brahmā"), 梵辅天 (brahma-purohita, "Ministers of Brahmā"), and 大梵天 (mahā-brahmā, "Great Brahmā"); the second dhyāna corresponds to 少光天 (parīttābha, "Lesser Radiance"), 无量光天 (apramāṇābha, "Immeasurable Radiance"), and 极光净天 (ābhāsvara, "Uttermost Radiance"); the third dhyāna corresponds to 少净天 (parītta-śubha, "Lesser Purity"), 无量净天 (apramāṇa-śubha, "Immeasurable Purity"), and 遍净天 (śubha-kṛtsna, "All-Pervading Purity"); the fourth dhyāna corresponds to 无云天 (anabhraka, "Cloudless"), 福生天 (puṇya-prasava, "Fruit of Merit"), and 广果天 (bṛhat-phala, "Great Fruit"). This is not a cosmic map for imaginary travel, but an explanation within the Buddhist doctrine of karma and its fruits: the meditative karma long cultivated and matured by the mind responds to corresponding levels of existence.

For 不还者 (anāgāmin, non-returners), the situation is different: by "interweaving" (间杂熏修) the 无漏 (anāsrava, outflow-free) fourth dhyāna with the tainted fourth dhyāna, according to the five grades of lower, middle, superior, superior-excellent, and supreme, they correspond respectively to the five 净居天 (śuddhāvāsa, "Pure Abodes"): 无烦天 (avṛha, "Free of Affliction"), 无热天 (atapa, "Free of Heat"), 善现天 (sudṛśa, "Beautiful Manifestation"), 善见天 (sudarśana, "Beautiful Vision"), and 色究竟 (akanistha, "Summit of Form"). Here one must not conflate the tainted dhyāna cultivated by ordinary people, the dhyāna cultivated by noble ones with outflow-free wisdom, and the great abode of freedom attained by bodhisattvas through the supreme cultivation of the tenth ground. All may use the language of "abiding," but the practitioners' degree of severing defilements and their position on the path are not the same.

The four formless attainments are 空处 (ākāśānantya-āyatana, sphere of infinite space), 识处 (vijñānānantya-āyatana, sphere of infinite consciousness), 无所有处 (ākiñcanyāyatana, sphere of nothingness), and 非想非非想处 (naiva-saṃjñā-nāsaṃjñāyatana, sphere of neither-perception-nor-non-perception), each also having lower, middle, and superior grades of cultivation and corresponding celestial beings. The formless realm has no distinctions of physical location, yet it still has what the *Yogācārabhūmi-śāstra* calls distinctions of "住所作" (abiding and its activities). Furthermore, one who skillfully cultivates 无想定 (asaṃjñi-samāpatti, attainment of non-perception) may be reborn among the 无想有情天 (asaṃjñika, beings without perception). The attainment of non-perception also cannot be equated with nirvāṇa: the temporary non-arising of certain mental perceptions is not the same as having completely cut off ignorance (无明, avidyā) and craving (贪爱, tṛṣṇā).

Third, it is the "path of the gods" (诸天天道) as a cause leading to celestial rebirth. The *Saṃyuktāgama* also speaks of four kinds of celestial paths: recollecting the Tathāgata with joyful approval (随喜, anumodanā), recollecting the Dharma with joyful approval, recollecting the Saṃgha with joyful approval, and making a vow not to give rise to anger (瞋, pratigha) whether in fearful or secure circumstances. Joyful approval is not merely verbal praise: the sūtra presents a sequence in which recollection gives rise to joy, joy to bodily and mental ease, and then the experience of pleasure and the mind's attainment of 三昧 (samādhi, concentration). Non-anger tests whether this wholesome mind can pass through real-world pressure, rather than existing only in favorable circumstances.

Strictly speaking, the "path of the gods" explains the causes leading toward the celestial destinies, and should not be indiscriminately equated with "dhyāna as divine abode." The classical sources place them in close contexts because 天住 comprises three facets: meditative practice as abiding, corresponding karmic fruits, and causes tending toward celestial rebirth. They must be understood as interrelated, yet also distinguished by level.

The *Yogācārabhūmi-śāstra* also explains the relationship between the divine abode and 天眼 (divya-cakṣus, divine eye) in three ways: the divine eye arises in dependence on dhyāna, is a fruit of dhyāna, and is sustained by dhyāna; hence it is called the "divine eye." This does not mean that merely paying slight attention to the breath will produce the divine eye, nor can imagination, dreams, or occasional visual experiences be recognized as the divine eye. What the treatise speaks of is the "utterly complete, perfectly pure" fruit of dhyāna, with explicit and demanding conditions of cultivation.

The place of 天住 on the path of liberation especially needs to be made clear. Concentration can cause the mind to leave the coarse disturbances of the desire realm and become an important basis for contemplating impermanence, suffering, and non-self, even for cutting off defilements; but "deep concentration," "feeling sublime," and "already liberated" are three different things. If concentration still accords with ignorance and craving, although it can bring prolonged ease and even celestial rebirth, when its karmic fruit is exhausted one has still not transcended saṃsāra. The classical sources, after speaking of the fourth dhyāna, immediately propose contemplating form, feeling, perception, volitional formations, and consciousness (色、受、想、行、识) as disease, tumors, darts, and killers, even moving toward 上流般涅槃 (upward-stream parinirvāṇa); this precisely shows that concentration is not the endpoint: the mind is first trained to be capable of abiding, and then must use wisdom to see that all objects of grasping are unreliable, in order to move from "dwelling well" to "no longer bound by birth and death."

A Walkthrough in Daily Life

Imagine a very contemporary morning: you are squeezed into a commuter carriage, your phone buzzes with a work message, and your partner sends a reproachful remark. Your body tightens, your mind quickly rehearses an argument, and your fingers are already preparing a reply.

The first step is not to use the breath as an emergency sedative, but to know the in-breath and out-breath truly. If the breath is long, know it is long; if short, know it is short. The entire bodily formation formed by the chest, abdomen, shoulders, and neck together with the breath is also within awareness. The easiest mis-mapping here is: "I should control my breath to be deep and slow." The starting point of 安那般那念 is knowing, not forcing; the stillness of the bodily formation comes from sustained awareness and gradual pliancy, not from holding the breath or suppressing emotions.

The second step is to see the coarse verbal activity: "How dare he say that," "Today is definitely ruined," "I must explain myself right now." You do not have to argue with every thought, nor pretend it does not exist; you simply stop adding fuel to it repeatedly. As the coarse signs gradually cease, what may remain is only a slight warmth in the chest, an inclination to feel offended, a subtle defensive posture. This can help one understand the sūtra's direction from "dwelling in coarse reflection" to more subtle abiding—but one should not claim on this basis to have entered the dhyāna described in the treatises. A moment of focus in daily life can only serve as an entry point for practice; it cannot be equated with the attainment of the four dhyānas.

The third step: you recollect the possibility of awakening represented by the Buddha, the path of abandoning greed and aversion indicated by the Dharma, and the people who genuinely practice this path within the Saṃgha, and from this arises joyful approval. This "recollecting the Buddha, recollecting the Dharma, recollecting the Saṃgha" is not reciting a few words to embolden yourself under pressure, but turning the mind back toward trustworthy values: could there be a little less retaliation, a little more clarity, in this moment?

The fourth step: test for non-anger. You may choose not to reply immediately, or simply write: "I'm on my way; I can see you're upset; let's talk properly tonight." Not giving rise to anger does not mean allowing oneself to be harmed, nor does it mean canceling boundaries; it is refusing to let harm automatically replicate itself as further harm. One may still refuse when refusal is called for, and should still leave dangerous relationships, but not with ill will as the driving force.

The fifth step: observe that this experience has no fixed, single "self" governing the whole: bodily tension belongs to the level of 色 (rūpa, form); discomfort is 受 (vedanā, feeling); recognizing that sentence as reproach, taking a certain tone as hostility, is the perceiving and labeling of 想 (saṃjñā, perception); wanting to strike back, suppress, explain, and continuously organizing the next reaction is the volitional activity of 行 (saṃskāra, volitional formations); and the discernment of these objects is 识 (vijñāna, consciousness). The most common error here is to describe 色 only as the physical body, 想 as idle fantasy, and 行 as external action. In fact, 色 includes the inner body and the outer material forms made of the four great elements; 想 is the taking up of signs and discriminating; 行 is the volitional activity that propels and shapes experience, not limited to whether one actually presses "send."

The sixth step: if the mind, through training, gives rise to coolness, brightness, and stability, do not rush to possess it: "This is the real me," "I've finally entered a higher state." The ease brought by 天住 may be enjoyed, yet one should still observe its conditioned arising, its change, and its cessation. Otherwise, craving for calm will replace craving for stimulation; the exterior becomes quieter, but the bondage is not uprooted.

The same walkthrough applies to scrolling on a phone: first be aware of the breath and body, recognize the restlessness before the fingers unconsciously swipe, see the volitional formation of "one more scroll," observe the brief pleasure and its deflation, without using suppression to counterfeit equanimity. It also applies to overtime work and parenting: abiding is not making oneself into a person who never tires, but clearly knowing how fatigue, irritation, and urgency arise, and gaining a space before action that is not taken over by anger.

However, all of this only illustrates the direction of practice through everyday experience. Complete dhyāna has its conditions of moral conduct, dispassion, sustained cultivation, and meditative signs; one cannot certify it with a calm moment on a commute.

Why Contemporary People Need It

Contemporary life constantly contends for the right to decide "where the mind dwells." Notifications, short videos, performance metrics, and instant responses in relationships together train the mind to dwell in the next stimulus. We think we are merely using tools, but we are also being trained: attention becomes ever more fragmented, desires ever more short-lived, emotions ever more in need of immediate expression.

天住 raises a fundamental question: can your mind only dwell in the stimuli arranged for it by the outside world, or can it learn to choose its own dwelling?

The significance of 安那般那念 is, first of all, to reclaim this capacity for choice. The breath is too ordinary to display identity, yet always present; taking it as the object, the mind begins to learn to sustain itself without novelty, approval, or a sense of control. 静虑 carries this capacity not to be swept along by circumstances to a deeper, more stable level. Recollecting the Buddha, Dharma, and Saṃgha, and non-anger, extend concentration from private comfort to value orientation and interpersonal ethics: if one's "meditation" only makes one more able to endure overtime and compete more efficiently, without reducing greed, anger, and harmfulness, then it is at most a technique of attention, not yet the full embodiment of the Buddhist direction of concentration.

One may use a limited analogy from algorithmic life: recommendation systems reinforce certain content based on repeated clicks, and the mind likewise forms habits through repeatedly following certain thoughts. Constantly following anger, anger becomes a familiar dwelling; constantly practicing joyful approval, non-anger, and mindfulness, the mind forms another kind of habitable place. But this is only a metaphor to help understand 熏习 (vāsanā, perfuming); consciousness, karma, and algorithms are not the same kind of thing, and computational models cannot prove Buddhist theories of rebirth or celestial realms.

From the perspective of the path of liberation, the true value of 天住 is not merely "making me comfortable," but giving the mind enough stability, purity, and plasticity to observe truly: all experience arises in dependence on conditions, and the blissful concentration state is not an eternal self or what belongs to a self. If one only seeks rebirth in heaven, 天住 remains a fine but limited path within saṃsāra; if, based on concentration, one arouses outflow-free wisdom, it is then incorporated into the path of renunciation. The problem is not that celestial bliss is bad, but that any place of birth cannot provide ultimate insurance. The Dharma does not require despising ease; it requires seeing the boundary of ease.

Common Misreadings and Clarifications

One: "天住 means dwelling in heaven."

Inaccurate. "Dwelling" first of all means the mind taking sublime meditative practice as its abode; birth in a corresponding celestial realm is a possible karmic fruition level. The cause, the present meditative state, and the future place of rebirth are related, but cannot be conflated.

Two: "天住 means ascending to heaven after death."

The heavens spoken of in Buddhism are still within dependent origination, karmic fruition, and arising and ceasing; they are not the dwelling of an eternal creator, nor a final destination that, once granted, is never lost. Directly translating Buddhist heavens as "heaven" in the sense of other religions obscures their impermanent and saṃsāric nature.

Three: "As long as I watch my breath, I have already entered 天住 or the four dhyānas."

Watching the breath is the entry point of 安那般那念; the *Saṃyuktāgama* does indeed use 安那般那念 to correctly explain 天住, but the sūtra simultaneously presents the depth of progression from coarse to subtle, and of dwelling repeatedly over long periods. Being able to remember the breath as a beginner and the full abiding in the fourth dhyāna are not the same attainment. A conceptual connection cannot substitute for the actual conditions of meditative achievement.

Four: "The four dhyānas are four levels of increasingly intense pleasure."

Inaccurate. At least for the fourth dhyāna, which the sources prominently highlight, its characteristic is not more intense excitement, but the cessation of pain and pleasure, the extinction of grief and joy, dwelling in equanimity that is neither painful nor pleasant, with pure mindfulness and one-pointedness. The deepening of concentration cannot simply be drawn as a rising curve of pleasant intensity.

Five: "Equanimity (舍) means having no emotions and not caring about anything."

Equanimity is the balance of the mind not being deflected by pleasure and pain; it is not numbness. A numb person may not see others' suffering; one who possesses equanimity clearly knows what is happening, yet does not react automatically from greed and anger. Non-anger is likewise not weakness, but not handling boundaries and conflicts with hostility.

Six: "The attainment of non-perception (无想定) or the sphere of neither-perception-nor-non-perception (非想非非想处) is nirvāṇa."

No. They are extremely subtle concentration states or corresponding planes of rebirth, still belonging to 有為法 (saṃskṛta-dharma, conditioned phenomena). The temporary stilling of certain mental activities is not the same as greed, anger, and delusion being eradicated from the root. Concentration can suppress defilements; liberating wisdom must see through and cut off the ignorance and grasping on which defilements depend.

Seven: "Attaining concentration necessarily produces the divine eye, and any vision is the divine eye."

The *Yogācārabhūmi-śāstra* says the divine eye depends on dhyāna, is a fruit of dhyāna, and is sustained by dhyāna—this states its causal conditions within a rigorous system of practice; one cannot infer that every meditator will necessarily produce it, nor can one self-certify hallucinations, dreams, vivid imagination, or visual anomalies as supernormal powers. In the case of persistent anomalous perception, one should not resort only to religious explanations while neglecting necessary physical and mental health assessment.

Eight: "Since 天住 can lead to heavenly rebirth, it has already completed the path of liberation."

This is the most critical misreading. Heavenly rebirth is a sublime fruition of wholesome and meditative karma, but it still has birth, and therefore still has change and eventual end. 天住 can be powerful provision for the path of liberation, but it cannot automatically replace insight into the impermanence, suffering, and non-self of the five aggregates (五蕴, pañca-skandha). Concentration answers whether the mind can abide, become pliant, and unify; wisdom further asks whether even the purest dwelling deserves to be grasped as self and what belongs to self.

Nine: "Since 天住 is not the endpoint, cultivating it is unnecessary."

Nor is this correct. A boat is not the far shore, but it is an important tool for crossing the river. An untrained mind, often just as it is about to observe greed and anger, is already carried away by them; concentration gives the mind the capacity not to follow immediately. What truly needs to be avoided is not concentration, but possessing the concentration state as identity and mistaking temporary purity for ultimate liberation.

Thus, the deepest reminder of "天住" is not to encourage us to pursue a more splendid world than reality, but to let us see: the mind is always dwelling somewhere, and is always shaped by the objects in which it repeatedly dwells. One can let the mind move from distraction into mindfulness, from anger into non-anger, from coarse pursuit into dhyāna; but ultimately one must see with wisdom that even the most sublime dwelling is dependently arisen and cannot be grasped. Abiding well is the path; no longer being bound by any dwelling is the direction pointed to by liberation.

Canonical EntryAI-generated

天住(divya-vihāra)为佛教关于「住」之重要概念,泛指以殊胜定行为住处、由此感得诸天界果报之修持。本条目依《杂阿含经》与《瑜伽师地论》两部经论之论述,呈现此概念之多层面貌。

一、定义与核心要义

天住,谓以安那般那念、四静虑等胜妙定行为住处,并由此感得诸天果报。

二、主要阐述

《杂阿含经》对「天住」之论述见于三处脉络,呈现三层含义:

其一,以安那般那念为天住之正说。经云:「若有正说,圣住、天住、梵住、学住、无学住、如来住,学人所不得当得,不到当到,不证当证,无学人现法乐住者,谓安那般那念,此则正说。所以者何?安那般那念者,是圣住、天住、梵住,乃至无学现法乐住。」 佛于一奢能伽罗林中二月坐禅,先行入息出息长短、一切身觉,乃至身行休息、灭出息之「麁思惟住」;继而止息麁思惟,「更入微细思惟,多住而住」。三天子夜诣佛所,第三天子评曰:「非为时到,亦非时向至,此则修住,是阿罗诃寂灭耳。」 「修住」即微细思惟住,亦为天住之具体展现。

其二,以第四禅具足住为天住。经云:「若比丘如是行、如是形、如是相,离苦息乐,前忧喜已灭,不苦不乐舍,净念一心,第四禅具足住……如四禅,如是四无色定,亦如是说。」并说行者若不尔者,或生因性果实天、福生天、少福天。

其三,以诸天天道为天住之修因。经说有四种诸天天道:念如来事、念于法事、念于僧事之三随喜,加无瞋恚为上诸天天道之自誓。

《瑜伽师地论》直接界定:「此中静虑说名天住。」 本论进一步说明天眼「依彼故,是彼果故,彼摄受故」,由于天眼依于静虑、是静虑之果、又为静虑所摄受,且为「极圆满、善清净」之静虑果,故称「天眼」。又依初、二、三、四静虑,各分下、中、上品善修习,随其所应生梵众天、梵辅天、大梵天;少光天、无量光天、极光净天;少净天、无量净天、遍净天;无云天、福生天、广果天。对不还者,以无漏第四静虑「间杂熏修」有漏第四静虑,分下、中、上、上胜、上极五品,生无烦、无热、善现、善见、色究竟五净居天。十地菩萨由极熏修第十地,得生超过净宫之大自在住处。四无色定(空处、识处、无所有处、非想非非想处)亦各分下、中、上品修习,有相应随行天众同分,以「住所作」有差别;善修无想定者生无想有情天。

三、不同部类与译本的表述差异

《杂阿含经》所用「天住」之相关术语至少有三种:安那般那念(anāpānasmṛti)、四禅具足住及四无色定、诸天天道。《瑜伽师地论》则以「静虑」直接作为天住之解说语,并以「静虑」统摄四静虑与四无色定;对无色界天之差别,则用「住所作」一词。

两部经论之内涵各有侧重:《杂阿含》将天住广涉现法乐住之定行(安那般那念)、上界天界之果报(四禅具足住感得之天界)、人天善趣之修因(诸天天道)三义;《瑜伽师地论》则将天住收摄于静虑一语之下,侧重定境之因果——静虑为天眼之所依、所生之因、摄持之条件。

四、与相关概念的关系

天住常与圣住、梵住、学住、无学住、如来住并列为「六住」,安那般那念被视为六住之共通正说。天住与天眼关系密切:天眼乃天住(静虑)之果,依静虑而起。天住亦与四禅、四无色定、无想定等定境名相密切相关,天住即后者之住处义。其所感果报则涉及欲界诸天(如因性果实天、福生天、少福天)、四静虑天、五净居天、无色界天、无想天等。

五、代表性原文引用

《杂阿含经》:「若有正说,圣住、天住、梵住、学住、无学住、如来住……谓安那般那念,此则正说。」

《杂阿含经》:「若比丘……离苦息乐,前忧喜已灭,不苦不乐舍,净念一心,第四禅具足住……若不尔者,或生因性果实天,若不尔者,生福生天,若不尔者,生少福天。」

《杂阿含经》:四种诸天天道——念如来事、念于法事、念于僧事之随喜。

《瑜伽师地论》:「此中静虑说名天住。」

《瑜伽师地论》:天眼「依彼故,是彼果故,彼摄受故」。

雜阿含經T0099 · 阿含部

本經論述「天住」的核心表述,是將其與「聖住、梵住、學住、無學住、如來住」並列,共同指向安那般那念(ānāpānasati),並以此作為現法樂住的內涵。

一、由麁入微的安那般那修行階次

世尊於二月中以安那般那念坐禪思惟住,行相為:入息出息時如實知,長短息、一切身覺入息出息如實知,身行休息乃至滅出息亦如實知。此層修持,世尊自評為「麁思惟住」;於此止息後,更入「微細修住」而多住。此從麁至微的階次揭示:天住並非單一靜態境界,而是含有由淺入深、如實觀照呼吸與身覺的漸修過程。

二、三天子觀察與「修住」之判定

世尊住於微細思惟時,有三天子以極上妙色過夜來至其所,分別發言:第一天子言「沙門瞿曇時到」,第二天子言「此非時到,是時向至」,第三天子則斷言「非為時到,亦非時向至,此則修住,是阿羅訶寂滅耳」。發言層次由「時到」推至「時向至」,再訂正為「修住」,顯示天人相應中,天界眾生能辨別修行者所處的安住層次;第三天子的判斷與世尊自述由麁入微的過程相應,故此「修住」即為天住境界的具體落實——非取滅、非向滅,而是寂滅中安住。

三、以安那般那念統攝諸住

佛告諸比丘:若有正說聖住、天住、梵住、學住、無學住、如來住,而謂「學人所不得當得,不到當到,不證當證,無學人現法樂住」者,即是安那般那念,此為正說。此以「學人未得、無學人現法樂住」對比,說明諸住本質皆是安那般那念,並以無學者現法樂住為其究竟成就。本經獨特用詞方面,稱阿羅漢為「阿羅訶」、稱佛姓為「瞿曇」、合稱為「沙門瞿曇」。

四、天人相應的安住意涵

本經未將天住描述為死後生天之果,而是以世尊現證之安那般那念為其內涵。三天子來至其所,意味此安住境界感得天人護讚、現前相應;天人相應非指外在感通,而是指安住之心與天界寂靜相契合。經末諸比丘「歡喜奉行」,顯示此天住之教乃可踐行、可受持之法。

瑜伽師地論T1579 · 瑜伽部

《瑜伽師地論》對「天住」之論述,以「靜慮」一詞作為其本質內涵。經文明確宣示:「此中靜慮說名天住」,直接將「天住」等同於「靜慮」之禪定本身,顯示本論以禪定即為天人相應之安住境界。此定義出現於論述「八言說句」與「六種略行」之隨念宿住段落中。

一、「天住」與「天眼」之三重因緣

本論以三種因緣解釋靜慮所成之眼何以稱為「天眼」:其一,「眼依彼故」(眼依止於靜慮);其二,「是彼果故」(靜慮為眼之因);其三,「彼攝受故」(靜慮攝受此眼)。可見「天住」(靜慮)乃「天眼」得以成就之依據、果報與涵攝範圍。

二、天眼之「極清淨」與「超過於人」

本論指出,由善清淨靜慮為因而得之天眼,具「極圓滿」、「極清淨」之德,是「善清淨靜慮果故」所致。其名號「超過於人」,與人中所立之名迥然不同(「名字皆不相似」)。相較於欲界天中亦有「生得」之清淨天眼(「名相似轉清淨天眼」),但人中畢竟無有此類天眼(「人中亦無」),故由靜慮所感之天眼更為殊勝。

三、天住與諸天眾同分之詳細對應

本論以「眾同分」一詞標示所生之天類別,詳述由「善修習」靜慮(下、中、上品)所感得的諸天果報:初靜慮下中上品善修習已,當生梵眾天、梵輔天、大梵天眾同分中;第二靜慮善修習已,當生少光天、無量光天、極光淨天眾同分中;第三靜慮善修習已,當生少淨天、無量淨天、遍淨天眾同分中;第四靜慮善修習已,當生無雲天、福生天、廣果天眾同分中。

四、不還者與五淨居天

本論特別指出,若屬不還者,以無漏第四靜慮間雜熏修有漏第四靜慮,於下品、中品、上品、上勝品、上極品善修習已,隨其所應,當生五淨居天眾同分中,即無煩天、無熱天、善現天、善見天、色究竟天。

五、無色界天與無想定天

若於空處、識處、無所有處、非想非非想處下中上品善修習已,當生空處等隨行天眾同分中。本論特別說明:「彼諸天無有形色,是故亦無處所差別。然住所作有其差別」,顯示無色界天雖無形色方所之別,然安住與所作仍有差別可分。又,若於無想定善修習已,當生無想有情天眾同分中。

總結:本論以「靜慮即天住」為核心定義,透過「善修習」之品類差別,建立從色界諸天、無色界天到無想天的完整天住層次,並以「天眼」之超越性作為天住果德之具體展現。
