What This Concept Is About

世間不可樂想 (Sanskrit: *sarva-loke-'nabhirati-saṃjñā*, "the contemplation of finding no delight in the world"), in brief, is a contemplative practice in which the practitioner, by deeply observing that the world and all conditioned activities (有為行法, saṃskṛta phenomena; 諸行, sarva-saṃskārāḥ, all formations) are entirely endowed with impermanence (無常, anitya), suffering (苦, duḥkha), and no-self (無我, anātman), breaks through craving for and attachment to the world, and gives rise to a pure mind of renunciation (厭離心).

In the 《大方等大集經》 (Mahāvaipulya Mahāsaṃnipāta Sūtra), the Buddha, at the request of Ājñāta Kauṇḍinya (阿若憍陳如), systematically unpacks this practice. To understand the concept fully, one must not narrow it to a merely emotional pessimism or world-weariness; rather, one must clarify the three dimensions defined in the scripture: the scope of the "world", the levels of contemplation, and its place in the path to liberation (解脫道).

1. What Is the "World": the Container World, the World of Sentient Beings, and the "Three Formations"

The scripture's division of the "world" is very precise, falling into two main categories plus one essential equivalence:

* The world of sentient beings (眾生世間/眾生世, sattva-loka): refers to the sentient beings of the five destinies (五趣, pañca-gatayaḥ) who revolve in birth and death — hell (地獄), animals (畜生), hungry ghosts (餓鬼), humans (人), and gods (天). * The container world (器世間/器世, bhājana-loka): refers to the forty places on which sentient beings depend for survival (including twenty places in the desire realm (欲界, kāma-dhātu), sixteen in the form realm (色界, rūpa-dhātu), and four in the formless realm (無色界, ārūpya-dhātu)). * The world is precisely the "formations": the scripture further states that "the world is precisely the formations" (世間者即是行), directly reducing the essence of the entire world to the three formations (三行) — the bodily formation (身行, kāya-saṃskāra, the in-and-out breath), the verbal formation (口行, vāc-saṃskāra, applied and sustained thought and speech), and the mental formation (意行, citta-saṃskāra, perception, feeling, and mind-nature). This means that the world is not an object independent of body and mind; it is precisely the fabrication and operation of these three formations that constitutes the whole of the world.

2. The Specific Levels of Contemplation and Their Canonical Analogies

For the practitioner to give rise to the contemplation of no delight in the world, the contemplation must unfold along three levels with extremely fine, penetrating observation:

* First level: the container world and the five destinies * The hell destiny: contemplate the beings suffering in the eight great hells (八大地獄) (the scripture calls the Sañjīva hell "the hell of dying once and living once," 一死一活地獄). They suffer extreme pain; even upon seeing lovely forms (妙色, supremely beautiful sights), they never give rise to even a sliver of joy. * The animal destiny: contemplate how animals, devoid of any sense of shame, constantly harm one another for the sake of survival. * The hungry ghost destiny: contemplate how hungry ghosts perpetually suffer hunger and thirst, eating only molten iron and hot pus. * The human destiny: contemplate how the human body inevitably possesses the pressing sufferings of birth, aging, sickness, and death. * The god destiny: contemplate how gods of the desire realm are burned by the fire of craving and face impermanent decay; how gods of the form realm, though possessed of profound meditative absorption, are still defiled (有漏, sāsrava) and not yet liberated; and how gods of the formless realm, though their lifespans are extremely long, still cannot escape the fall upon the exhaustion of their reward and the danger of giving rise to wrong views. * Second level: contemplation of the three formations (body, speech, mind) * The bodily formation (in-and-out breath): contemplate the in-and-out breath (出入息, ānāpāna) entering and leaving through the pores of the entire body, and truly discern that it is "originally non-existent, now present" (本無今有, arising only through the convergence of causes and conditions). Its impermanent nature is like a bubble on water (水上泡) and like lightning traced on water (如電畫水) — a flash across the water's surface, gone in an instant. * The verbal and mental formations: contemplate that applied and sustained thought and speech (覺觀, vitarka-vicāra; the verbal formation) and the mind-nature of perception and feeling (想受, saṃjñā-vedanā; the mental formation) are likewise "originally non-existent, now present," without self and without substance. In each moment of the arising and ceasing of the "formations," give rise to a mind of remorse and realize that they are not pleasurable. * Third level: contemplation of clothing, food, and dwelling * Clothing: contemplate that the clothes one wears are in essence like a wrapping of human skin smeared with blood — nothing more than a dwelling place for foul worms. * Food: contemplate at mealtime that the alms bowl in one's hand is like an impure skull (髑髏); that the food is like worms in a corpse; that the rice is like powdered bone; and that the soup, water, and milk-curd are like pus, blood, urine, and excrement. * Dwelling: contemplate that the house one lives in is like a hell; that the building timbers are like human bones; that the plastered walls are like flesh covering a skeleton; and that the bed, mattress, and bedding are like human skin.

3. Its Place in the Path to Liberation

世間不可樂想 is by no means an endpoint; it is a crucial springboard for breaking through ignorance (無明, avidyā) and reaching outflow-free wisdom (無漏智):

1. Penetrating the aggregates, bases, and elements (陰入界, i.e., 五陰/五蘊, pañcaskandha, the five aggregates; 十二入/十二處, dvādaśāyatana, the twelve sense-bases; 十八界, aṣṭādaśa-dhātu, the eighteen elements): through this contemplation, the practitioner can penetrate the fact that all dharmas of the aggregates, bases, and elements are suffering, empty, and without self, thereby cutting off the fundamental attachment to self and others, body and mind. 2. Accomplishing the three conformative forbearances (三中順忍, anulomikī-kṣānti): through thorough cultivation of this contemplation, the practitioner can attain the "three conformative forbearances" — the conformative forbearance of emptiness (空順忍), the conformative forbearance of signlessness (無相順忍), and the conformative forbearance of wishlessness (無願順忍) (collectively called in the scripture the "patient acceptance of reality as it is," 如實法忍). 3. Perfectly possessing the dhāraṇī of accord with the wishless (隨無願陀羅尼): because the practitioner no longer has any expectation or wish for the world, he perfects the "dhāraṇī of accord with the wishless" (無願順陀羅尼), and with this power subdues the māras (魔) and dispels the various calamities of the world. 4. Severing defilements and realizing the fruits: thoroughly cutting off craving for the desire realm (欲貪), craving for the form realm (色貪), craving for the formless realm (無色貪), all pride (驕慢, māna), and ignorance, one passes straight through the path of liberation to realize the fruit of stream-entry (須陀洹果, srotāpanna, the first fruit) and even the fruit of arhatship (阿羅漢果, arhat, the fourth fruit).


Walking Through It in Daily Life

If we map this practice layer by layer onto the life-scenarios of contemporary people, we can see how it shatters the illusion of "pleasure" (樂想) in our daily existence.

Scenario One: Scrolling on Phones and Consumerist Parties (mapping: the desire-realm gods and craving for sense objects)

Lying in bed late at night, your finger swipes unconsciously through short videos or e-commerce pages. Exquisite food, luxurious resort hotels, enviable lifestyles flash across the screen. Our brains keep secreting dopamine, and we think we are enjoying "pleasure."

* Classical mapping: this is the archetypal "burning of craving for sense objects" (欲愛焦灼) of the desire-realm gods and the human destiny. * Mistaken mapping: people commonly take this dopamine stimulation to be happiness, or imagine that earning enough money will let them remain permanently in this pleasure. * Walking through the contemplation of no delight in the world: observe the nature of these images and desires — they are merely neural electrical signals triggered by stimulation, vanishing in an instant (本無今有, "originally non-existent, now present"). The moment desire is satisfied, it is immediately followed by a deeper emptiness and deprivation (like the hunger and thirst of hungry ghosts). Observe that this algorithm-manipulated party is, in its essence, entirely pervaded by oppression and impermanence, and contains not a single thing truly worthy of delight.

Scenario Two: Designer Clothing and Fine Dining (mapping: the contemplation of clothing and food)

You put on an expensive luxury trench coat and sit in a high-end restaurant enjoying aged steak, delicate desserts, and artisanal cheese.

* Classical mapping: the contemplation of clothing and food in daily life. * Mistaken mapping: people all too easily take the material "refinement" and "cleanliness" (淨想) of things as the dignity and enjoyment of life. * Walking through the contemplation of no delight in the world: * Clothing: when wearing fine clothes, see through to their function — merely wrapping this body of skin, blood, and fat; between the fabric and the flesh is a breeding ground for microscopic bacteria and foul worms. * Food: looking at the exquisite tableware and food, see through to their essence — the container is merely a "skull" holding food; the premium ingredients, once chewed and mixed with saliva, are no different from worms in a corpse or powdered bone; the soups, broths, and milk-curd, once they enter the stomach and undergo digestion and metabolism, ultimately flow together with pus, blood, urine, and excrement. Contemplating in this way, one will not be enslaved by the appetites of mouth and belly.

Scenario Three: Buying a House and a Cozy Bedroom (mapping: the contemplation of dwellings)

Having spent two generations' savings to buy a fully furnished apartment, you stand in the spacious living room, looking at the wood-floored bedroom and the soft bedding, and feel the stable pleasure of "finally I have a support, finally I have a home."

* Classical mapping: the contemplation of dwellings and the container world. * Mistaken mapping: taking a building of brick, wood, and concrete as an eternal haven, and taking material space as the resting place of the soul. * Walking through the contemplation of no delight in the world: see through this house — the steel and timber are like the skeleton of a corpse; the plastered walls and painted surfaces are like the flesh covering the bones; the soft bedding is like the skin wrapping the body. If one gives rise to strong attachment in the mind, and to maintain the mortgage is forced into endless rat-racing and anxiety, then this house, on the spiritual dimension, is no different from a "hell."

Scenario Four: Overtime, Rat-Racing, and Verbal Skirmishes (mapping: the contemplation of the three formations and the animal/hell destinies)

In workplace meetings or project tug-of-wars, you undermine each other over KPIs and trade sarcastic remarks; or on the subway commute, you see a car full of exhausted office workers with numb eyes.

* Classical mapping: the contemplation of the three formations (body, speech, mind) and the animal destiny (constant mutual harm) and the hell destiny. * Mistaken mapping: taking these workplace confrontations and emotional fluctuations as a real "I" being insulted or a real "I" winning. * Walking through the contemplation of no delight in the world: * Contemplate the bodily formation: notice your own breathing (in-and-out breath) in the crowded subway; each inhalation and exhalation, entering and leaving through the pores, is "originally non-existent, now present," like a bubble on water (水上泡), like lightning flashing across water (電畫水) — there is no fixed "I" doing the breathing at all. * Contemplate the verbal and mental formations: contemplate the quarreling and speech in the meeting room (the verbal formation) and the anger and calculation in the mind (the mental formation); both are the arising-and-ceasing mind-nature brought together by causes and conditions, without self and without substance. See sentient beings harming one another over limited resources, like the animal destiny; see body and mind oppressed by pressure, like the suffering of hell. Thereby give rise to a mind of remorse amidst the formations, and no longer cling to victory or defeat.

Scenario Five: Pursuing Meditation and Spiritual Refuge (mapping: the contemplation of the form and formless realm gods)

Tired of worldly competition, you attend an exclusive silent meditation retreat, or become absorbed in some purely spiritual doctrine or psychological concept, experiencing a certain tranquility of body and mind and thinking you have been "liberated."

* Classical mapping: the contemplation of the form-realm and formless-realm gods. * Mistaken mapping: taking meditative states, spiritual refuges, or high-grade emotional value as ultimate liberation. * Walking through the contemplation of no delight in the world: contemplate that this tranquility is still a conditioned, conjointly arisen state (有漏, with outflows). Once the retreat ends and you return to reality, or when a major upheaval occurs, the meditative power recedes, and you fall back into anxiety (退墮) — and may even give rise to the arrogance and wrong view of "I have attained the Way." One must recognize that even the highest spiritual enjoyment is, in essence, still not free of impermanence and suffering.


Why Contemporary People Need It

In contemporary society, we are experiencing an unprecedented "seduction of pleasure" and "micro-management of desire." Algorithm-driven short videos, precisely targeted consumerism, and constantly reshaped "indicators of the refined life" are applying high-frequency dopamine stimulation to our brains.

1. Breaking the Dopamine Cycle and the Trap of the "Perception of Pleasure"

Modern neuroscience and brain science have revealed the mechanism of desire: dopamine does not represent real pleasure; it represents only "the prediction of and craving for pleasure." When we pursue some consumption or achievement, the brain is in a state of high-pressure "prediction error"; the moment desire is satisfied, dopamine rapidly falls back, and what follows is a deeper emptiness and withdrawal reaction.

* The Buddhist-scientific comparison: brain science precisely describes the biological circuit of "desire-driven → brief satisfaction → deeper deprivation"; and 世間不可樂想 already pointed out this truth two thousand years ago — the so-called "pleasure" of the world is, in essence, only the temporary remission of suffering, a phantom phenomenon that is "originally non-existent, now present, like a bubble on water" (本無今有、如水上泡). * Limitation and clarification: the limitation of brain science is that it can only attribute this to neurotransmitters and evolutionary mechanisms; it cannot offer a path of liberation that transcends this circuit. The Buddhist cultivation of the "contemplation of no delight," by contrast, is precisely to thoroughly destroy the "perception of pleasure" (樂想) and the "perception of purity" (淨想) regarding these arising-and-ceasing phenomena, thereby cutting off the root of the circuit of desire.

2. Fighting "Mental Attrition" and the Hijacking of Body and Mind

Contemporary people so easily fall into anxiety, depression, and internal attrition because we take the fabrications of body and mind (the aggregates, bases, and elements; the three formations of body, speech, and mind) as a real "I," and take dwelling, clothing, food, and social status as the ultimate support of life. Once these external things waver, the mind collapses entirely.

Cultivating 世間不可樂想 is like injecting a cool sedative into feverish attachment. Through extremely stark, penetrating analogies, it carries us through the glossy surface of matter and fame to see their underlying ground of "suffering, emptiness, and no-self." When we no longer harbor unrealistic "attachment to pleasure" (樂著) and "wishful seeking" (願求) toward the world, the mind is instead released from the taut grip of possessiveness and enters the stable state of conformative forbearance of emptiness, conformative forbearance of signlessness, and conformative forbearance of wishlessness (空順忍、無相順忍、無願順忍).


Common Misreadings and Clarifications

Misreading One: Equating the "Contemplation of No Delight in the World" with "Negativity, Depression," or "World-Weariness and Suicidal Tendencies"

* Clarification: this is the most widespread misunderstanding. Depression or world-weariness is a pathological mental state whose core is hatred, despair, and ignorance; its underlying layer is still a clinging and obsession with the world — a sense that "it ought to have been beautiful but did not turn out as hoped." * Essential difference: the contemplation of no delight in the world is a clear, calm contemplation of wisdom. Its starting point is seeing reality as it is (suffering, emptiness, no-self); its endpoint is cutting off craving, pride, and ignorance, and giving rise to a pure mind of renunciation and the conformative forbearance of wishlessness. One who cultivates this contemplation does not have a heart of despair and callousness, but is no longer deceived by the phantom bubbles of the world, and thereby attains great ease and great freedom.

Misreading Two: Thinking "No Delight" Is Merely Aesthetic Fatigue or Life Burnout

* Clarification: life burnout (e.g., feeling that work has become meaningless after a long time, or being tired of a certain food) is merely a psychological sense of weariness. This kind of burnout is easily covered over by new stimuli (changing jobs, taking a trip, buying a new consumer product) and continues to spin within the orbit of desire. * Essential difference: the "contemplation of no delight" is a thorough vision of the arising-and-ceasing nature of the aggregates, bases, and elements (陰入界) and the three formations of body, speech, and mind. It realizes that even if one changes the environment or obtains new stimuli, their nature of "originally non-existent, now present, impermanent like a bubble on water" (本無今有、無常如水上泡) will never change. This is cutting off the illusion about the world at the very root of cognition, not a temporary emotional ennui.

Misreading Three: Taking the "Contemplation of Clothing, Food, and Dwelling" as Extreme Self-Mortification, Hygiene Obsession, or Abandoning Life Conditions

* Clarification: the scriptures' contemplation of clothing as the dwelling of foul worms, food as pus, blood, and powdered bone, and dwelling as flesh covering a skeleton — this in no way requires the practitioner to eat rotten food, wear ragged clothes, or deliberately wreck the living environment, still less does it make one develop a mental hygiene obsession. * Essential difference: these contemplations are extremely penetrating "antidotes" (解毒劑), specifically used to counter the "perception of purity" (淨想, the view that the body and external things are clean and beautiful) and the "perception of pleasure" (樂想, the view that enjoying these things brings lasting happiness). Their purpose is to remind us: clothing, food, and dwelling are merely tools for sustaining life (using the provisional to cultivate the real, 借假修真); the mind must not become a slave to matter. In daily life, the practitioner may still dress, eat, and dwell normally, but the mind is already free of attachment and hindrance.

一、定义与核心要义

「世间不可乐想」(sarva-loke-'nabhirati-saṃjñā)是指修行者观照器世间、众生世间及一切有为行法皆具足无常、苦、无我,从而对世间不生乐着、生起厌离的修行法门。

二、主要阐述

在《大方等大集经》(大集部·《大方等大集經》)中,佛陀应阿若憍陈如之请,详细宣说了「一切世间不可乐想」的修行法门。该经对此概念的论述具有独特的系统性,主要从「世间」的定义、具体的观想对象、以及修行的利益三个维度展开。

首先,关于「世间」的定义,经中将其划分为两种:一是「众生世间」(或称「众生世」),指地狱、畜生、饿鬼、人、天等五趣众生;二是「器世间」(或称「器世」),指众生居住的四十处,包括欲界二十处、色界十六处、无色界四处。此外,经中进一步提出「世间者即是行」,将世间等同于「三行」,即身行(入出息)、口行(觉观言说)与意行(想受)。

在具体观想对象上,修行者需对上述世间生起不可乐想,具体分为以下三个层面:

1. 器世间与五趣观:修行者需观想八大地狱(等活地狱在经中又称为「一死一活地狱」)中受苦的众生,彼等众生即使见到妙色亦不生乐;观畜生趣无惭愧心、常相残害;观饿鬼趣常患饥渴、食铁浆热脓;观人身具足生、老、病、死等诸苦;观欲界天人受欲爱焦灼与无常之苦;观色界天人虽然修得禅定,但仍有有漏、未得解脱等苦;观无色界天人则有退堕及生起邪见之苦。

2. 三行观:修行者需观身行(出入息)从毛孔出入,谛知其「本无今有」,无常之态犹如水上泡或电画水;观口行(觉观)与意行(心性)亦是本无今有、无我无实,从而于诸行之中生起悔心,修不可乐想。

3. 生活衣食房舍观:修行者在日常生活中亦需时时作观:观所穿着的衣服如同人皮、血涂,为恶虫所居住;在饮食之时,视钵盂如同不净的髑髅,视食物如同死尸中的虫,视饭食如骨末,视羹、浆、乳酪等如同脓血或大小便;观所居住的房舍如同地狱,材木如同人骨,泥壁如同以肉覆盖骸骨,床褥则如同人皮。

修行此想具有巨大的利益。经中指出,此修行能令行者获得「三种顺忍」(即空顺忍、无相顺忍、无愿顺忍,或称「如实法忍」);能彻底断除欲贪、色与无色贪、一切憍慢与无明;能观「阴入界」一切法性苦空无我,从而证得须陀洹果乃至阿罗汉果;并且能够具足「无愿顺陀罗尼」(或称「随无愿陀罗尼」),以此摧伏恶魔、消弭世间的种种灾难。

三、不同部类与译本的表述差异

在《大方等大集经》(北凉昙无谶译)的文本中,对于相关概念和修行名相存在多种不同的表述方式,这些用词的分歧与对应关系如下:

1. 世间分类的表述:经中在论述世间时,既使用「众生世间」与「器世间」的完整表述,亦有简称为「众生世」与「器世」之处。 2. 地狱名称的独特表述:在描述八大地狱时,经中将传统佛教音译或意译的「等活地狱」独特地表述为「一死一活地狱」。 3. 蕴处界名相的表述:经中使用了较为古雅的译语,以「阴入界」或「阴界」来指代五阴(五蕴)、十二入(十二处)、十八界;并且直接以「十二入」指代十二处。 4. 修行成果与忍力的表述:对于修行此想所获得的忍力,经中一方面称之为「三种顺忍」(即空顺忍、无相顺忍、无愿顺忍),另一方面又将其统称为「如实法忍」。 5. 陀罗尼名称的表述:对于行者所具足的陀罗尼,经中存在「无愿顺陀罗尼」与「随无愿陀罗尼」两种不同的译名表述。

四、与相关概念的关系

「世间不可乐想」与多个核心佛教概念有着密切的内在关联:

1. 与「三行」的关系:经中将「世间」等同于「行」,即身行、口行、意行。因此,修世间不可乐想,本质上就是对这三行的无常与无我进行观照。通过谛知出入息(身行)及觉观心性(口、意行)的「本无今有」,行者得以在诸行中生悔,进而成就不可乐想。 2. 与「阴入界」的关系:阴入界(五阴、十二入、十八界)是构成世间与众生自体的基本要素。世间不可乐想的深化,即是观照「阴入界」一切法性皆是苦、空、无我。只有透彻认识到阴入界的非乐与不净,行者才能断除对自他自体的执着,进而证得从须陀洹至阿罗汉的圣果。 3. 与「三种顺忍」及「无愿顺陀罗尼」的关系:世间不可乐想是通往高深法忍与陀罗尼的基石。通过此想的修习,行者得以契入空、无相、无愿的境界,获得「三种顺忍」(如实法忍),并具足「无愿顺陀罗尼」(随无愿陀罗尼),从而具备摧伏魔怨、消弭灾难的强大力量。

五、代表性原文引用

为彰显经文原意,特摘录《大方等大集经》中关于此法门的关键论述如下:

1. 关于世间的定义与地狱观:「世间有二种:一者众生世,二者器世。……一死一活地狱受苦众生,虽见妙色亦不生乐。」 2. 关于三行与无常观:「世间者即是行,所谓身行、口行、意行。……观身行出入息,谛知本无今有,无常如水上泡。」 3. 关于饮食与生活观:「视钵如不净髑髅,视食如死尸虫,视󰉓如骨末,视羹、浆、乳酪如脓血或大小便。」 4. 关于修行功德与法忍:「修一切世间不可乐想,能令行者获得三种顺忍,所谓空顺忍、无相顺忍、无愿顺忍,亦名如实法忍;能断一切欲贪、色无色贪、憍慢无明,具足随无愿陀罗尼。」

增壹阿含經T0125 · 阿含部

本經論述「世間不可樂想」時,將其置於「十想」修行體系中,作為十項修習之首出者而加以標舉。以下就其核心表述與獨特側面進行梳理。

一、十想總綱與不可樂想之位置

世尊告諸比丘:修行十想者,便能盡有漏、獲通作證,漸至涅槃。此十想分別為白骨想、青瘀想、脹想、食不消想、血想、噉想、有常無常想、貪食想、死想、一切世間不可樂想。經中將此十想視為一完整的修行階梯,凡是修習者皆得漏盡、證涅槃界之果。

二、不可樂想被推為「最為第一」

在十想之中,一切世間不可樂想被稱為「最為第一」,此一評價為本經所獨特彰顯。經中以「又是」轉折強調:十想之中以此想為最上,顯示本經特別重視此觀對於解脫的關鍵功用。原文云:「十想之中,一切世間不可樂想最為第一」。

三、不可樂想與持信奉法者同證

經文進一步說明所以然之理:「其有修行不可樂想,持信奉法,此二人必越次取證。」即修習不可樂想者,與持信奉法者,此二類人皆能不依次第、超前取證。值得注意的是,本經在此使用「越次取證」一語,凸顯此觀能令行者超越常規階次而速疾得果,此為本經對此概念的獨特表述。

四、用語形式

本經以「一切世間不可樂想」為全稱,又簡稱「不可樂想」,二者並用。此處以「一切世間」限定所觀之境,意指對一切世間法皆作不可樂之觀想。又,本經以「有漏」稱煩惱、以「涅槃」稱究竟解脫、以「作證」與「取證」並用表示親證果位,皆為本經所採之術語形式。

五、修習處所與勸勉

末後世尊勸勉:若在樹下靜處露坐,當思惟此十想。顯示此觀之修法宜於寂靜露地、樹下端坐之處所進行。世尊結語以「當作是學」勗勉諸比丘,諸比丘聞佛所說,歡喜奉行。

大般涅槃經(北本)T0374 · 涅槃部

《北本大般涅槃經》論「世間不可樂想」,要義如下:

一、修習之加行與所依 經云:「智者具足如是四想,能修世間不可樂想。」所謂「四想」,文中先以乞食正願為示——願乞者得飽、施者得福、我若得食為療毒身、修善利益施主——以此正願為前行,方得起此不可樂想。

二、世間過患之觀察 智者觀察世間過患,歸納為數端: (1) 一切世間無處不有生老病死,我身亦無處不生;既無一處得離此四相,則不應於世生樂。 (2) 一切世間無有進得而不退失,是故「世間定是無常」,既是無常,智人不應樂著。 (3) 一一眾生周遍經歷一切世間,具受苦樂;雖得梵天乃至非想非非想天之身,命終還墮三惡道。 (4) 雖為四王乃至他化自在天身,命終生畜生道、或為師子虎豹豺狼象馬牛驢。 (5) 觀轉輪聖王統四天下、豪貴自在,福盡則貧困、衣食不供。

三、世間物體即是苦 智者復觀舍宅、衣服、飲食、臥具、醫藥、香花瓔珞、種種伎樂、財物寶貨等,皆為「離苦」而施設,然其體即是苦。經云「云何以苦欲離於苦」,猶如人身嬰重病,雖有種種音樂、香花瓔珞,終不貪愛;智者於世間物,亦不生愛樂、不作樂想。

四、世間非歸依等六處 經中歸結:「智者深觀一切世間,非歸依處、非解脫處、非寂靜處、非可愛處、非彼岸處、非是常樂我淨之法。」若貪樂世間則增長黑闇、遠離光明。經以闇喻世間、明喻出世:「闇即無明,光即智明,是智明因即是世間不可樂想」——明確認定此想為生起智明之親因。

五、不貪世間、轉貪智明 經云:「一切貪結雖是繫縛,然我今者貪於智明,不貪世間。智者深觀如是法已,具足世間不可樂想。」顯示「不可樂想」之完成,並非絕對斷貪,而是將貪轉向——不貪世間,轉貪智明。

六、次第轉入死想 修世間不可樂想已,即「次修死想觀」:觀壽命為無量怨讎所遶、念念損減;以山瀑水不得停住、朝露勢不久停、囚趣市步步近死、牽牛羊詣屠所等為喻,層層轉入死想之修習。

術語方面,本經以「世間不可樂想」全稱為題,未見別名異稱;觀察主體稱「智者」;所破斥對象稱「世間」;期證境界稱「智明」、「出世」;與之對立者稱「無明」、「黑闇」;世間之物列為「舍宅、衣服、飲食、臥具、醫藥、香花瓔珞、種種伎樂、財物寶貨」。

大方等大集經T0397 · 大集部

《大方等大集經》論「世間不可樂想」,始終與「食不淨想」並稱為「二相」,並與他方佛所傳之「無願(順)陀羅尼」密切結合,乃此經之獨特取向。

一、釋「世間」之範疇。經中明言世間分二:眾生世(天、人、餓鬼、畜生、地獄五道)與器世(眾生所居之處)。器世有四十:欲界二十處(八大地獄各十六圍繞)、色界十六、無色界四。經中逐一列名。

二、依器世廣觀三界皆苦。地獄眾生雖見妙色,以心逼切不生樂想,反增眾苦;畜生身量自微塵至千萬由旬,常行黑闇、相害之心;餓鬼裸形,常飢渴,鐵丸熱膿難得;人身具生老病死、愛別離、怨憎會、求不得諸苦;欲界六天有果報不等、愛別離等苦;色界十六住處乃有漏禪定,未具八正、未得緣覺如來三昧等苦;無色界四處有漏三昧,退時邪見等苦。經自結云:「如是八種和合觀時,智慧之人乃能獲得……此則名為一切世間不可樂想」。

三、依三行觀察無常。此經獨以「行」釋世間:身行(出入息)、口行(覺觀言說)、意行(想受)。數息觀察,知息本無今有如水上泡;覺觀因心,心亦本無今有、無歸依、無有我。作是觀時,於諸行中修不可樂想。

四、依生活資具觀察(極具厭離之喻):衣如血塗皮、爛臭蟲處;鉢如血塗髑髏;食如死屍蟲;飯漿如糞汁;餅如人皮;錫杖如人骨;乳酪如膿血;菜茹如髮毛;房舍如地獄,木為人骨、土為人肉;湯藥丸散亦令生厭。此段比喻之驚駭具體,為本經特色。

五、所破與所得。修集此想,能斷欲貪、色貪、無色貪、憍慢、疑、調戲、無明,得無學地。得三順忍——空順忍、無相順忍、無願順忍,見一切法苦空無我,得須陀洹果乃至阿羅漢果;無量眾生得法眼淨、諸漏永盡、發菩提心、得不退心。

六、與「隨無願陀羅尼」之關聯。此經最獨特處,在於明言「二種一切世間不可樂想」即「隨無願陀羅尼(無願順陀羅尼)」微妙之義,且為智德峆王如來命焰德藏菩薩摩訶薩所送來此土之陀羅尼(另一處亦稱德華密佛遣虛空密菩薩持來)。經中廣說此陀羅尼破魔、伏外道、增長三寶等無量功德。

七、並列之諸不淨想。此經為淨眾生四顛倒,廣列無常想、苦想、無我想、死想、膖脹想、爛想、膿想、青瘀想、蟲噉食想、臭想、骸骨離散想等。

本經用詞特色:以「器世」「眾生世」分判世間、以「四十種住處」總攝三界、以「隨無願陀羅尼/無願順陀羅尼」總結此二相、以「三順忍」配無願觀、以「八種和合觀」指地獄至無色界之八段觀察,皆為此經獨特名相。
