What Is "Joy and Pleasure Born of Seclusion" (離生喜樂)?

In classical Theravāda and Early Buddhist texts (such as the *Majjhima Āgama* [中阿含經] and *Saṃyukta Āgama* [雜阿含經]), "Joy and Pleasure Born of Seclusion" (*離生喜樂*, Pali: *vivekaja-pīti-sukha*, Sanskrit: *vivekaja-prīti-sukha*) refers to the distinct mental and physical rapture and happiness experienced when a practitioner steps away from the five sensual desires of the sense realm (*五欲*) and unwholesome states (*惡不善法*), entering the First Jāna (*初禪*, first meditative absorption).

To grasp this concept, we must understand its precise components within the Buddhist path of liberation (*解脫道*):

1. "Departure/Seclusion" (離) as the Direct Cause

The happiness of the First Jhāna is not generated by acquiring, possessing, or stimulating something new. Rather, it is born strictly from departure and detachment (*離*). * **Leaving the Five Sensual Desires (*五欲*):** Sight, sound, smell, taste, and tactile stimulation sought for sensual indulgence. * **Leaving Unwholesome States (*惡不善法*):** The five hindrances (*五蓋*)—sensual desire (*欲貪*), ill will (*恚害*), sluggishness/torpor (*惛沉睡眠*), restlessness/worry (*掉悔*), and debilitating doubt (*疑*).

In Buddhist phenomenology, feeling (*受*, *vedanā*) is categorized into worldly "sensual feeling" (*欲受*)—which relies on external sensory objects—and "feeling free of sensual desire" (*離欲受*). *Joy and Pleasure Born of Seclusion* is the canonical baseline of "feeling free of sensual desire" (*離欲受*).

2. The Internal Dynamics: Rapture (喜) and Happiness/Pleasure (樂)

In the First Jhāna, two distinct qualities arise: * **Rapture (*喜*, *prīti*):** An uplifting, exhilarating mental joy and energetic lightness. * **Happiness/Pleasure (*樂*, *sukha*):** A deeply soothing, peaceful, and bodily-pervading sense of ease and well-being.

3. The Classic Analogy: The Bath-Powder Ball (澡豆譬喻)

Early scriptures describe the physical-mental experience of this state using a precise simile: > *"Just as a bath attendant or apprentice might knead soap powder (*澡豆*, bath flour used anciently to cleanse body oils) in a bronze dish, sprinkling water over it until the moisture soaks through every grain, forming a moist, cohesive ball where no part remains dry; even so, the practitioner's body is drenched, saturated, filled, and pervaded in every single corner by the joy and pleasure born of seclusion."* (*Majjhima Āgama*)

This analogy emphasizes that meditative absorption (*禪定*) is not a cold, disembodied intellectual state. It is an embodied experience where rapture and ease soak through every cell and perception.

4. The Structural Place in the Path and Its Limitations

While *Joy and Pleasure Born of Seclusion* is a radiant landmark, the Buddhas and Arhats evaluate it with absolute precision: * **"Applied and Sustained Thought" (*有覺有觀* / *尋伺*):** The First Jhāna still retains coarse and subtle mental movement—directing attention to the meditation object (*覺/尋*) and staying anchored to it (*觀/伺*). Because of this active mental focus, noble ones refer to the First Jhāna as "noble movement/instability" (*聖說移動*), recognizing that it is not yet ultimate stillness. * **Transition to "Joy and Pleasure Born of Concentration" (*定生喜樂*):** To surpass the First Jhāna, the meditator must quiet *applied and sustained thought*, moving into the Second Jhāna (*第二禪*), where joy and pleasure are born directly from still, unified concentration (*定生喜樂*) without active mental directing. * **The Danger of Clinging to the Flavor of Seclusion (*離味*):** If a meditator becomes addicted to the bliss of seclusion, consciousness clings outward to the state (*依彼住彼,緣彼縛彼*), resulting in "consciousness not remaining within" (*識不住內*). Such attachment can lead to rebirth in the Brahma Realm (*梵身天*), enjoying celestial bliss but remaining bound within the cycle of samsara (*意行生*). * **The Vipassanā Method (*觀照*):** To utilize the First Jhāna for full liberation, the practitioner must not cling to its signs or forms (*行、形、相*). Instead, they contemplate the five aggregates (*五陰*: *色、受、想、行、識*) present in this state as "like a disease, an abscess, a dart, a murder, impermanent, painful, empty, and non-self" (*如病、如癰、如刺、如殺、無常、苦、空、非我*). Only through this insight do they exhaust all defilements (*盡諸漏*) and attain Nibbāna.


A Walkthrough in Contemporary Life (生活裡的走查)

To truly understand *Joy and Pleasure Born of Seclusion*, we must map it against our modern daily experiences—and clarify where modern people usually misidentify it.

``` ┌─────────────────────────────────────────────────────────────────────────────┐ │ MODERN LIFE vs. FIRST JHĀNA │ ├───────────────────────────────┬─────────────────────────────────────────────┤ │ Everyday Sensual Traps │ First Jhāna (離生喜樂) │ ├───────────────────────────────┼─────────────────────────────────────────────┤ │ • Infinite Scrolling / Feeds │ • Disconnection from external stimuli │ │ • Binge-watching / Gaming │ • Internal stillness free of sensory noise │ │ • Fast Dopamine Rewards │ • Saturated bodily ease (澡豆譬喻) │ │ • Craving & Withdrawal cycles │ • Mental freedom from the 5 Hindrances │ └───────────────────────────────┴─────────────────────────────────────────────┘ ```

Scene 1: Binge-Watching and Late-Night Phone Scrolling

* The Modern Illusion: You come home after a exhausting 10-hour workday, order takeout, collapse onto the couch, and scroll through short videos or binge a drama series. You feel a sudden surge of relaxation and tell yourself, *"I’m finally escaping work and getting some quiet joy."* * The Canonical Mapping: This is not *Joy and Pleasure Born of Seclusion* (*離生喜樂*); it is classic sensual feeling (*欲受*). Your brain is chasing rapid dopamine releases supplied by external sights (*色*) and sounds (*聲*). The mind is actively fed by the five senses (*五欲*). The moment you put the phone down, an underlying restlessness (*掉悔*) or emptiness returns. * Where People Mis-map: Mistaking sensual distraction (*以欲驅欲*) for genuine seclusion (*離*).

Scene 2: The "Escape to Nature" Weekend Getaway

* The Modern Illusion: You drive to a remote mountain lodge, turn off your work notifications, sit by a quiet stream, and feel a deep wave of relief washing over your body. You think, *"I have attained the Buddhist joy of seclusion!"* * The Canonical Mapping: This is an external form of physical isolation (*身遠離*), which is a helpful prerequisite, but it is not yet Jhāna. If your mind by the stream is still reviewing past conflicts (*恚害*), daydreaming about future promotions (*欲貪*), or drifting into sleepy haziness (*惛沉*), the five hindrances (*五蓋*) are still active. *Joy and Pleasure Born of Seclusion* requires the complete setting down of internal hindrances, not just changing your GPS location.

Scene 3: Deep Focus during Overtime Work or Coding ("Flow State")

* The Modern Illusion: A software developer or writer enters a hyper-focused state at 2:00 AM, working smoothly for hours without noticing time, experiencing high thrill and satisfaction. * The Canonical Mapping: While this shares the elements of *applied and sustained thought* (*尋伺*), it is typically driven by an ambition to complete a task, solve a puzzle, or earn a reward—which remains tethered to the realm of form and desire. It lacks the essential factor of being free from worldly desire and unwholesome states (*離欲、離惡不善法*).

Scene 4: The Authentic Experience of *Joy and Pleasure Born of Seclusion*

* The Modern Reality: A practitioner sits in meditation after gradually abandoning worries about work, family, and online entertainment. As breath awareness unifies the mind, the frantic mental hunger for external stimulation quiets down. Suddenly, a profound lightness emerges from *not wanting anything*. A physical warmth and soothing ease permeate from the chest to the limbs—exactly like water saturating a bath-powder ball (*澡豆譬喻*). The body feels effortless, light, and completely replenished without eating, drinking, or consuming any media.


Why Contemporary People Need It

Modern society is built on an extroverted dopamine economy. Algorithms, notification badges, social media feeds, and consumer culture are engineered to keep human consciousness constantly reaching outward (*心出外灑散*).

``` [External World / Sensory Inputs] ──(Triggers Craving)──> [Mind Reaches Outward (心出外灑散)] │ (Frustration & Exhaustion) ▼ [First Jhāna (離生喜樂)] <──(Dropping Hindrances)─── [Turning Inward (識住內)] ```

1. Breaking the Trap of "Exhaustive Consumption"

Most modern people attempt to cure stress through consumption: eating richer food, buying more goods, seeking higher sensory stimulation. However, sensory indulgence (*欲受*) always carries a hidden tax—craving, tolerance, and withdrawal. *Joy and Pleasure Born of Seclusion* proves to the practitioner that the highest immediate physical and mental bliss does not come from taking something in, but from letting things go.

2. Re-sensitizing the Nervous System

Neuroscience and modern psychology note that constant digital stimulation desensitizes the brain's reward pathways. *(Note: While modern neurobiology studies how meditation alters the default mode network and parasympathetic tone, these scientific observations describe physiological correlates rather than Buddhist liberation itself.)* What the Buddhist framework shows is that when the mind stops chasing external objects, its innate capacity for peace and joy naturally re-emerges.

3. Providing the "Linchpin" for Deep Insight

In the解脫道 (path of liberation), an individual who relies purely on willpower to resist temptation often fails because the human mind cannot sustain bare deprivation forever. *Joy and Pleasure Born of Seclusion* provides an indispensable wholesome alternative happiness (*離欲樂* / *遠離樂*). Once a practitioner tastes this unworldly ease, worldly attractions lose their obsessive grip, making genuine contemplative insight (*觀照*) natural and sustainable.


Common Misunderstandings and Clarifications

Misunderstanding 1: "Joy and Pleasure Born of Seclusion is the Ultimate Enlightenment."

* Clarification: Classical scriptures explicitly warn against viewing the First Jhāna as the final goal. * It still contains active mental directing (*有覺有觀*), which noble ones describe as an unstable "movement" (*聖說移動*). * If a meditator becomes addicted to its flavor (*離味*), their mind becomes bound to it (*緣彼縛彼*), resulting in "consciousness not remaining within" (*識不住內*) and causing rebirth in celestial realms (*梵身天*) rather than full liberation.

Misunderstanding 2: "To experience Seclusion, I must escape society and live as a hermit."

* Clarification: While physical quiet (*身遠離*) helps beginners, the core of *Viveka* (seclusion) in *離生喜樂* is mental seclusion from unwholesome states (*心遠離* / *離惡不善法*). A person living in a crowded metropolis who successfully suppresses the five hindrances during breath meditation can enter *Joy and Pleasure Born of Seclusion*, whereas a hermit in a cave whose mind is consumed by resentment or fantasy remains trapped in the sense realm.

Misunderstanding 3: "Because it feels good, I should just rest in this bliss without doing anything else."

* Clarification: The Buddha instructed practitioners sitting in the First Jhāna to actively apply insight. Instead of dwelling on the peaceful form or sign (*不念行、形、相*), one must examine the five aggregates (*色、受、想、行、識*) present in that very state and observe them as "like a disease, an abscess, a dart,无常 (impermanent), 苦 (unsatisfactory), 空 (empty), and 非我 (non-self)". Only by seeing even this refined Jhānic experience as composite and impermanent does one break all attachments and achieve final Nibbāna.

Canonical EntryAI-generated

一、定义与核心要义 「离生喜乐」(vivekaja-prīti-sukha)是指修行者在修行过程中,通过远离欲界的五欲功德及恶不善法,进入初禅(第一禅)时所伴随并体验到的独特喜悦与快乐。在佛教的受阴分类中,因世俗五欲因缘所产生的感受被称为「欲受」,而初禅所伴随的「离生喜乐」则被明确定义为「离欲受」。它是修行者在禅定修持中所获得的阶段性成果,也是进一步向更高禅定层次迈进的基础。 二、主要阐述 1. 修持体验与身心特征:在具体的修持过程中,如修习「念身」与「观身如身」时,修行者会深刻体验到离生喜乐对身心的全面渗透。经中描述这种状态为「渍身润泽,普遍充满于此身中,离生喜乐无处不遍」,以及「处处润泽,处处敷悦,举身充满,无不满处」。为了形象地说明这种体验,《中阿含经》中提出了一个生动的「澡豆譬喻」:犹如工浴人或浴人弟子,用器皿盛放澡豆,并加水调和成抟,此时水分便会渍润、普遍充满于整个澡豆抟中,使其内外都受到水分的渗透而无处不周。比丘在初禅中体验离生喜乐充盈全身的情形,与此完全相同。这种随身行的修持,能使修行者「知上如真」,并在远离独住、精勤修行中断除心之诸患,获得定心。尊者跋陀罗亦对此高度赞叹,指出从该三昧起者会遍告大众:「极寂静者,离生喜乐,极乐者,离生喜乐。」凡是听闻此声的人,即被称为「闻第一」。 2. 对「离味」的执着与「识不住内」:尽管离生喜乐是初禅的殊胜体验,但修行者若对其产生执着,将会面临极大的危险。当比丘进入初禅时,其「识」可能会贪著于这种远离欲界所带来的滋味(即「离味」),从而「依彼住彼,缘彼缚彼」。这种因执著于初禅喜乐而导致心识向外攀缘、被其束缚的状态,在经中被称为「识不住内」。 3. 意行生与梵身天果报:初禅的离生喜乐与死后的生天果报(即「意行生」)有着直接的因果关系。如果比丘在入初禅、受离生喜乐时,对此禅定产生了乐欲和执着(彼此定乐欲住),并在其中安住、喜乐,那么他命终之后将会投生到「梵身天」中。经中特别强调,梵身天众生在彼处所享受的「离生喜乐」,与比丘在此世入初禅所享受的「离生喜乐」在性质上「无有差别,二俱等等」,因为后者正是前者在人间修习、广布的因行所感召的果报。 4. 观照方法与解脱道定位:在解脱道中,离生喜乐并非终点,而应被视为断除诸漏的资粮。经中强调,修行者不能对此产生执着,而应采取正确的观照方法。尊者阿难提出,真正的「乐第一」并非单纯体验此乐,而是「如所生乐,次第尽诸漏者」。具体而言,比丘在初禅「离生喜乐」具足住时,不应忆念初禅的行、形、相,而应当对其中的「色、受、想、行、识法」(即五阴)进行深入观照,作「如病、如痈、如刺、如杀、无常、苦、空、非我」的思惟。通过这种思惟,修行者能对这些法产生厌离、怖畏与防护,进而以甘露门自饶益,最终达到舍离、爱尽、涅槃的寂静境界。 5. 局限性与超越:在禅定的进阶序列中,离生喜乐具有明显的局限性。首先,初禅的「离生喜乐」状态中仍保有「有觉、有观」的心理活动,因此在圣者看来,这仍属于一种「移动」(即不稳定、动摇)的状态。其次,对于初禅的离生喜乐,佛陀明确说明「不得无、不得断、不得过度」。若要实现「过度」(即超越),修行者必须息灭觉、观,进入「内靖、一心,无觉、无观,定生喜、乐」的第二禅。若认为初禅「唯是为乐非余」是不正确的,因为在其之上还有更胜之乐,如第二禅的「定生喜乐」乃至想受灭等。 三、不同部类与译本的表述差异 在不同经藏及译本中,关于「离生喜乐」及相关禅定状态的表述存在一些独特的术语差异: 1. 寻伺状态的表述:对于初禅所伴随的寻伺心理活动,《中阿含经》与《杂阿含经》均采用了「有觉、有观」或「有觉有观」的表述。 2. 贪着禅乐的表述:《中阿含经》使用了独特的术语「离味」,专指对远离欲界所生喜乐的贪着;而《杂阿含经》则偏重于通过对五阴作「如病、如痈」等思惟来防范这种执着。 3. 天界果报的表述:《中阿含经》将初禅对应的天界明确指代为「梵身天」。 4. 禅定动摇与超越的表述:《中阿含经》使用「圣说移动」指代初禅中尚未止息的微细动摇,并以「过度」指代禅定层次的超越与晋升。 5. 观照对象的表述:《杂阿含经》在指导观照时,使用了「色、受、想、行、识法」这一术语来指代五阴。 6. 第二禅喜乐的表述:对于超越初禅后第二禅的喜乐,《中阿含经》表述为「定生喜、乐」;而《杂阿含经》则表述为「定生喜乐」。 四、与相关概念的关系 1. 与「定生喜乐」的关系:初禅的「离生喜乐」是因「离欲、离恶不善之法」而生;而第二禅的「定生喜乐」则是因「无觉无观」的禅定本身而生,后者在层次上高于前者,是前者的超越与晋升。 2. 与「欲受」及「离欲受」的关系:世俗五欲因缘所生之受为「欲受」,初禅的离生喜乐则属于「离欲受」,两者在性质上截然不同,后者是走向解脱的过渡状态。 3. 与「四种乐」的关系:在《杂阿含经》中,离生喜乐与「离欲乐、远离乐、寂灭乐、菩提乐」等概念密切相关,共同构成了佛教对不同层次快乐的系统阐述。 4. 与「识不住内」的关系:若修行者在体验离生喜乐时产生贪着(离味),其心识便会向外攀缘、被其束缚,从而陷入「识不住内」的状态,无法获得真正的内在寂静。 五、代表性原文引用 1. 《中阿含经》卷二十五:「比丘离欲,离恶不善之法,有觉、有观,离生喜乐,得初禅成就游。彼离生喜乐渍身润泽,普遍充满于此身中,离生喜乐无处不遍。犹如工浴人或浴人弟子,以器盛澡豆,水和作抟,水分渍润,普遍充满,无处不周。如是比丘离生喜乐渍身润泽,普遍充满于此身中,离生喜乐无处不遍。」 2. 《中阿含经》卷三十四:「若有比丘彼此定乐欲住,在彼安住,彼家、彼乐,命终生梵身天中。梵身天众生生彼处,受离生喜乐;比丘在此入初禅,受离生喜乐。此二离生喜乐,无有差别,二俱等等。」 3. 《杂阿含经》卷十七:「何等为离欲受?谓离欲、恶不善法,有觉有观,离生喜乐,初禅具足住,是名离欲受。」 4. 《杂阿含经》卷三十一:「比丘离欲、恶不善法,有觉有观,离生喜乐,初禅具足住。于榜、于行、于形、于相,不念、不思,但于彼处所生色、受、想、行、识法,观如病、如痈、如刺、如杀、无常、苦、空、非我。」

中阿含經T0026 · 阿含部

《中阿含經》論「離生喜樂」,主要置於兩套禪觀框架之中:一為「修習念身」,一為「觀身如身」(即四念處之身念處)。兩處行文高度平行,術語完全一致,皆作「離生喜樂」,不作他稱。

一、在「修習念身」脈絡中,經文以「復次,比丘修習念身」起句,述比丘「離生喜樂,漬身潤澤,普遍充滿於此身中,離生喜樂無處不遍」。此處「離生喜樂」並非孤立出現,而是作為一組遞進序列的首環:離生喜樂→定生喜樂→無喜生樂,三者依次而進。離生喜樂以「工浴人器盛澡豆,水和成摶,水漬潤澤,普遍充滿無處不周」為喻,強調水與豆和合、由外而內浸透的遍滿相。其後定生喜樂改以山泉自涌為喻(水從內出),無喜生樂改以蓮花水生水長為喻,三喻遞進,顯示離生喜樂尚帶「由離欲而初生」的意味,至定生喜樂則不假外緣、從定自發。此段結語為「斷心諸患而得定心,得定心已,則知上如真」,將離生喜樂定位為得定、知上如真的前行資糧。

二、在「觀身如身」脈絡中,經文先廣說安那般那念(念入息、念出息、覺一切身息等),而後接入同一組三階序列,離生喜樂仍居其首,喻亦同用澡豆。與念身段的差異在於結語:此處不說「知上如真」,而說「觀內身如身,觀外身如身,立念在身,有知有見,有明有達,是謂比丘觀身如身」。亦即同一離生喜樂體驗,在念身框架中指向「得定心→知上如真」,在觀身如身框架中則收攝於四念處「立念」「知見明達」的觀慧語境。兩處術語、譬喻全同,歸趣措辭略異,是此經並行兩套身觀法門的痕跡。

三、另有一處雖未直接使用「離生喜樂」四字,但語義密切相關:「樂在無欲,心存遠離,喜於無諍,受盡欣悅」。此句以「樂」與「喜」分說,而其所依為「無欲」「遠離」,正與「離生喜樂」之「離」(離欲惡法)相呼應。其後續以「猶如石山,風不能動,色聲香味,身觸亦然,愛不愛法,不能動心」,將此離欲之喜樂推向不動、盡受的解脫方向,較前兩段止於「遍滿身中」的禪定描寫更進一層,偏向受盡、心解的果位表述。

綜觀本經用詞:始終作「離生喜樂」,不作「離欲生喜樂」「初禪喜樂」等異稱;「離」字本身即含「離欲惡法」義,經文不另加「欲惡法」三字為限定。三階序列(離生喜樂、定生喜樂、無喜生樂)為本經固定術語組合,兩處重出而字句不異,可見是此經傳承中的定型句式。

雜阿含經T0099 · 阿含部

《雜阿含經》論「離生喜樂」,主要見於尊者阿難與尊者跋陀羅的問答經,另有一偈頌以異名「離貪欲樂」呼應同一義旨,以及六根不喜則解脫於苦的教說作為離欲之理的鋪墊。

一、核心表述與術語形式。本經以「離生喜樂」四字為定名,謂「有眾生離生喜樂,處處潤澤,處處敷悅,舉身充滿,無不滿處」。此處「離生」即由離欲而生,「喜樂」為所生之受;經文以「潤澤」「敷悅」「充滿」三詞層遞形容此喜樂遍滿全身,強調其為身心俱受、無一處不周遍的定中體驗。經中又記彼眾生「從三昧起,舉聲唱說,遍告大眾:『極寂靜者,離生喜樂,極樂者,離生喜樂。』」——以「極寂靜」與「極樂」二語並稱,顯示本經將離生喜樂定位為寂靜與樂受的統一,且須從三昧(定)中起已方能宣說,說明此喜樂以三昧為所依。值得注意的是,本經用「三昧」而非「三摩地」「等持」等譯語,用「眾生」而非「有情」,用「舉身充滿」形容遍滿,皆為劉宋求那跋陀羅譯筆的特徵。

二、離生喜樂與離喜之樂的層次區分。跋陀羅於同經中續言:「有眾生於此身離喜之樂潤澤,處處潤澤,敷悅充滿,舉身充滿,無不滿處,所謂離喜之樂,是名樂第一。」此處「離喜之樂」與前文「離生喜樂」形成對舉:離生喜樂猶帶「喜」,離喜之樂則已離喜而唯存「樂」,二者有淺深次第。本經以此二語分屬不同層次的定境,術語上嚴格區分「離生喜樂」(喜與樂俱)與「離喜之樂」(唯樂無喜),不混用、不互訓。

三、阿難的超越性判準。阿難對跋陀羅所列諸「第一」逐一以「次第盡諸漏」重新界定:「如所生樂,次第盡諸漏者,是名樂第一。」此非否定離生喜樂本身,而是將判準從定境體驗移至漏盡解脫——本經據此呈現一個獨特側面:離生喜樂若未導向盡漏,則尚非究竟之樂第一。此為《雜阿含經》在該概念上的不共表述,以解脫論收攝禪定論。

四、離欲不喜則解脫於苦。另一經中佛告諸比丘:「若於眼生喜者,則於苦生喜……我說彼不解脫於苦。」「若於眼不生喜者,則於苦不生喜……我說彼解脫於苦。」六根(眼耳鼻舌身意)準此。此處「不生喜」即離欲之實踐面向,為離生喜樂之前行基礎:於六根不生喜,方能離欲惡法,方有離生喜樂之生起。本經以「於……不生喜」的句式表達離欲,用語質樸,不假「離欲惡不善法」等禪支名目,而義理相通。

五、偈頌中的異名「離貪欲樂」。經末偈云:「得離貪欲樂,不生見於佛。」此「離貪欲樂」即離生喜樂之異稱,以「貪欲」代「欲」,語義更明確指向對貪的遠離所生之樂。本經於散文用「離生喜樂」,於偈頌用「離貪欲樂」,二名互見,歸一當知此為同義異譯式異名,非別指一法。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》以「離生喜樂」為初靜慮(初禪)之核心受用相,並從三個層面加以論述。

一、樂生三分中的定位。論主於「樂生三者」科中,將三靜慮九處所受之樂分為三種,其表述為:「謂彼安住離生喜樂、定生喜樂,離喜樂故,長時安住、長時離苦、長時受樂,故名樂生。」 據此,初靜慮以「離生喜樂」為名,第二靜慮以「定生喜樂」為名,第三靜慮以「離喜樂」為名。論主又特別指出「生靜慮中間都無喜樂應思」,即初、二靜慮之間的近分定(中間定)無喜無樂,卻仍攝於樂生天中,提示讀者注意此處名實之辨。

二、喜與喜受的體性辨析。論主進一步追問:「喜即喜受,以何為證知決定然?」並引二阿笈摩(二經證)為據:一者《辯顛倒契經》說「漸無餘滅憂等五根,第三定中無餘滅喜,於第四定無餘滅樂」;二者餘經說「第四靜慮斷樂斷苦先喜憂沒」。由此證成「第三定必無喜根,由此喜受是喜非樂」。 此處論主明確反對「餘部」所許——餘部謂「別有喜是心所法,三定中樂皆是喜受,故喜、喜受其體各異」;俱舍則據經證判定:喜即是喜受,非離喜受外別有一喜心所。 此辨析直接關涉「離生喜樂」中「喜」字的體性:初靜慮之喜即喜受本身,非另一心所。

三、染靜慮中離生喜樂之有無。論主設問:「如上所說諸靜慮支,染靜慮中為皆有不?」答曰「不爾」,並引「一類隨相說」:「初染中無離生喜樂,非離煩惱而得生故。」 此句揭示「離生」一詞的嚴格義理限定——離生喜樂必以「離煩惱」為生起之因,染污定(與煩惱相應之定)既未離煩惱,即不得有離生喜樂。論主又並列「有餘師說」:初二染中但無輕安,後二染中但無行捨,「大善攝故」,即輕安、行捨唯大善地法所攝,不與染心俱。 兩說並存,論主未加裁斷。

四、術語形式。本論一律用「靜慮」而非「禪」或「三摩地」指稱四禪;用「喜受」指稱喜之體性;用「離生喜樂」「定生喜樂」「離喜樂」為三靜慮受樂之固定名目;用「染靜慮」指與煩惱相應之定;引經證時稱「阿笈摩」(āgama)而非「經」或「教」。
