What this concept is about

*無喜生樂* is one short phrase, but it names a very specific experience inside the meditation sequence of the four *dhyānas* (四禪). Literally, "bliss (*sukha*) born in the absence of joy (*prīti*)." To hear it accurately you have to feel the difference between two words that English speakers, and modern Chinese speakers, routinely collapse into one — "happiness," or "快感." The early Buddhist meditation vocabulary refuses this collapse, because the third *dhyāna* is precisely the place where one of those two is dropped and the other is allowed to deepen.

The technical distinction, before anything else: In the early suttas and *āgamas*, *pīti* (Chinese 喜) and *sukha* (Chinese 樂) are sister-but-different factors of concentration. *Pīti* is the affective "swell" — the body's liveliness when the mind settles on its object: heart beating a little fuller, skin tingling with a fine excitement, attention lit up, an enthusiasm that wants to magnify itself. *Sukha* is what comes when that swell quiets into a steady ease — less fireworks, more warm light. The first *dhyāna* has both; the second *dhyāna* still has both but the *pīti* is more refined; the third *dhyāna* is the exact point where *pīti* is allowed to subside completely while *sukha* remains, and remains not as a passing mood but as a saturation of the whole body. The fourth *dhyāna*, *清淨心* ("pure mind"), goes even further and lets *sukha* itself subside, leaving only equanimity and pure clarity.

So the name *無喜生樂* is not a mood, and it is not a hedonic recommendation. It is a precise diagnostic for a precise stage: "joy has ceased; ease has been born."

Where it sits in the canonical text. The defining passage from the *Madhyama Āgama* / 《中阿含經》 (T0026) stacks the four *dhyānas* in a single, repeated rhythmic sentence:

初禪「離生喜樂」 / 二禪「定生喜樂」 / 三禪「無喜生樂」 / 四禪「清淨心」

The text does not give *無喜生樂* an abstract definition in the dictionary style. Instead it does three things, and each of them is necessary to grasp what the term points to.

1. Direct description of the felt body. *「漬身潤澤,普遍充滿於此身中,無喜生樂無處不遍。」* — "It soaks the body, pervades and fills this body, *無喜生樂* penetrates everywhere." Notice the bodily language: 漬 (to soak through, as cloth), 潤 (to moisten, as wood), 普遍充滿 (pervading and full). This is a physiology of *sukha* described from the inside. The Chinese word *沁* (permeate deeply) is almost the right verb; it is not a thought.

2. The lotus simile, in its precise position. *「猶青蓮華,紅、赤、白蓮,水生水長,在於水底,根莖華葉,悉漬潤澤,普遍充滿無處不周。」* — "Like a blue lotus, or a red, or crimson, or white lotus — born in water, grown in water, standing in water, its roots, stems, flowers, and leaves all *soaked and moistened*, pervaded and filled, nowhere untouched." The lotus is always given for the third *dhyāna* specifically; the earlier *dhyānas* have their own similes and you have to keep them straight. The first *dhyāna* is the *soap-pod simile* (澡豆喻): the pod needs water *and* rubbing to lather — the body is energized but conditioned by initial effort (離生, "born of seclusion," with active *vitakka-vicāra*, applied and sustained thought). The second *dhyāna* is the *deep-spring simile* (山泉喻): the spring wells up from inside and bubbles out without anyone pumping it — *sukha-pīti* now self-arises from concentration alone, with *vitakka-vicāra* quiet. The third *dhyāna* is the *lotus simile* because the lotus does not just touch the water from below — it lives *in* the water, root and leaf, every part saturated — *pīti* has dissolved into its element, *sukha* now suffuses everything that once had *pīti* in it.

3. The classification of pleasures as two kinds. A separate passage (also T0026) sorts all *sukha* into two columns: - *凡夫樂* (the ordinary world's pleasure): *「因五欲功德生喜生樂」* — the happiness that arises because of the five sense-objects. This is *「病本、癰本、箭刺之本,有食有生死,不可修」* — "the root of sickness, the root of a boil, the root of a thorn; it feeds and re-feeds death-and-rebirth; it cannot be cultivated (as a path)." - *聖樂* (noble pleasure): *「離欲、離惡不善之法,至得第四禪成就遊」* — the happiness that arises from renunciation and from dwelling in the fourth *dhyāna*. This is *「聖樂、無欲樂、離樂、息樂、正覺之樂,無食無生死,可修、可習、可廣布」* — "noble pleasure, desireless pleasure, the pleasure of release, the pleasure of quieting, the pleasure of right awakening; it does not feed death-and-rebirth; it can be cultivated, practiced, and broadcast."

*無喜生樂* belongs to the second column. It is the sensual-pleasure column inverted. That's important: even though the felt sensation is bodily and pleasant, it does not belong to the family of pleasures generated by stimulations, achievements, taste, money, status, or sex. It belongs to the family of pleasures generated by *purity of mind in stillness*.

**Its precise context in the *Madhyama Āgama* is *念身* (mindfulness of body), not 觀受 (observing feeling).** The technical term used in the text is not the later "念處 / 身念處" pair, but *念身* — and the closing refrain of the practice is *「觀內身如身,觀外身如身,立念在身,有知有見,有明有達」*. "Observe the body inside as body; observe the body outside as body; set mindfulness on the body; with knowing, with seeing, with clarity, with penetration." This is what the practitioner is doing *as* the lotus of *sukha* saturates them: they are watching the saturation, not identifying with it, not feeding on it, not writing a poem about it. *無喜生樂*, in this text, is the body-mind that mindfulness-with-clarity is *observing*, not a state that they have been told to manufacture. The *念身* scaffolding is what protects *sukha* from becoming the next *pīti* — the next swell that wants to magnify itself.

What the verse line contributes. *「樂在無欲,心存遠遠,喜於無諍,受盡欣悅。亦樂受盡,心不移動。」* — "Pleasure is in having no desire; the mind dwells in remoteness; joy is in non-contention; the exhaustion of feeling is gladness. When even this pleasure-of-feeling is exhausted, the mind does not move." This places *無喜生樂* next to *受盡* — the "exhaustion of feeling" — and the image *「猶如石山,風不能動」* — "like a stone mountain: the wind cannot move it." *Sukha* here is already approaching the threshold where even *sukha* is seen through as *feeling*, and therefore the fourth *dhyāna* ("pure mind," having let go of both *pīti* and *sukha*) can arise.

To put the whole thing in one breath: **無喜生樂 is what it is like when the buzzy excitement of the early *dhyānas* (喜) has faded into the background and a deep, body-wide quiet pleasure (樂) is left standing by itself — not as a reward, not as an experience to chase, but as the felt object that *念身* watches, already on its way to being seen as *feeling*, and therefore as impermanent.**

A well-known classical line you may have encountered in a slightly different context is *《心經》「照見五蘊皆空」*. The Heart Sutra is doing the *seeing-through* of *feeling* (受) at a more radical register; *無喜生樂* is a meditation-stage description of what *feeling* can become — saturated ease — on the way to that final seeing-through. Different altitude, same topic.


Walk-through in daily life

Let's *walk* the term through scenes you would recognize, mapping each piece of the classical definition one-to-one onto a contemporary moment. This is not a method to attain the third *dhyāna*; the classical text is careful that you do not get *無喜生樂* from these scenes, only *resonances* of its structure. The distinction matters.

1. Workout → cool-down. The run is over. The runner slows down. For the first few minutes there is *pīti*: heart still hammering, endorphin fizz, limbs trembling with adrenaline, every inhale pulsing — *喜*, the body's enthusiasm. Ten minutes later, walking back, the heart has quieted. The fizz is gone, but something warm, soft, expansive is left in the chest and legs. They are easy. They are not excited; they are not bored; the body feels *saturated* with a satisfaction that has no edge to it. That post-run saturation, when the excitement genuinely subsides and only the ease remains, is the *shape* of *無喜生樂*. Not the substance; the substances (dopamine, endorphins, lactate clearance) are biological. The *shape* — the transition from a buzzy enjoyment to a quieter enjoyment that fills the body — is what the early texts are pointing at.

Common misread, right here: many people think "the runner's high" is the experience. The runner's high is closer to second-dhyāna *定生喜樂*. The third-dhyāna shape is the still-satisfied body *after* the high has dissolved. It looks almost boring from the outside. It is the lotus at the bottom of the pond, not the spring gushing up from it.

2. Creative work after a breakthrough. You have been working on a problem for hours. The breakthrough arrives with *pīti* — excitement, raised shoulders, the urge to call someone. Then the call is over and you sit back at the desk. The problem is solved. There is a deep, quiet *rightness* in the body: the breath is even, the hands are warm, you do not need anything to be added to this moment. That quiet rightness, which has no surface activity but fills the whole bodymind, is the second *shape* of *無喜生樂*.

Common misread: equating *pīti* with "doing well." The third-dhyāna shape is *no longer needing to do well*. The early texts actually describe the *pīti* of earlier stages as a kind of bodily enthusiasm that *can* pull the mind back out — the mountain-spring of the second *dhyāna* is *bubbling*, which is beautiful but not yet stable. Stability arrives when even the bubbling stops.

3. The first few weeks with a person you love vs. the long settled years. New love is densely *喜*: the chest lift, the mental magnification, the urge to talk, the body alert even in sleep. Long-companionate love, when it is healthy, often has *less* of that *pīti* and *more* of a quiet *sukha* — being next to this person just *feels* like warm water covering the whole body. You are not excited; you are *eased*. If you map this onto the simile: *pīti* is the soap-pod lather in your hands; *sukha* is the cool water in which the lotus lives. Many people mistake the loss of the lather (the early *喜*) for the loss of love. The early Buddhist vocabulary suggests: you have just entered the lotus-pad. *Sukha* is still there. *Sukha* may even be deeper now.

Common misread (and a dangerous one): "if I don't feel the *喜* anymore, I must not love them." No — that is the very transition that *無喜生樂* names. In the language of the suttas, *pīti* is the *part* that comes and goes; *sukha*, when it is *sukha* of the noble kind, has a different weight.

4. Phone scrolling at 1 a.m. A whole different shape. You are tired but you scroll, hoping one more video will give you a lift. Each clip gives a tiny jolt — *喜* — and almost immediately demands the next one. The body is tense; the breath is shallow; the satisfaction never accumulates; only the wanting thickens. This is the *anti-shape* of *無喜生樂*. The simile would not be a lotus but a sponge squeezed dry and reaching for the tap. The cause, in the classical vocabulary, is that the pleasure being generated here is *凡夫樂* — "因五欲功德生喜生樂" — pleasure born of the agitation of the senses, which the text calls "病本、癰本、箭刺之本." It is a pleasure that makes a wound and promises to be the cure.

What would the *反向* map look like — that is, what is the equivalent *lay* moment of "letting the *pīti* dissolve"? Putting the phone down, dimming the lights, feeling the body's tiredness without trying to fix it. Easy to say; almost no one does it. *無喜生樂* is what happens *after* you do, in a stronger register, in a meditation hall rather than a bedroom. The bedroom version is faint; the meditation version is full. But the *movement* is the same: stop agitating the senses, let the body's innate *sukha* surface on its own.

5. Parenting, the second hour. A baby is crying. The first hour is dense with *喜*-flavored alertness: distress signal, plans, devices, attempts. The second hour is calmer — you are sitting in the rocking chair, the baby has fallen asleep on your chest, your breathing has dropped, your arms are warm and heavy. That heaviness is not boredom and not exhaustion; it is a clean, full *ease*. A *lotus* moment. The earlier structural facts (the smell of the baby, the smallness) are still there; what has changed is the loss of the *pīti*-charge. *Pīti* gone; *sukha* remains. You can map this without overclaiming — it is the *shape*, not the technical attainment.

6. Grief, the deep one. Many people mistakenly think meditation advice is "be happy." *無喜生樂* is not that. After the loss, the first months are *pīti*-shaped — weeping, memory surges, energetic flashbacks. Years later, the grief still comes, but a quieter floor has established itself under it. The body knows how to breathe again. Even the grief does not empty the *ease* out. This is not a description of what the third *dhyāna* feels like internally (the dhyāna is non-sensory, while the griever is in the world of form), but the *transition* — from *pīti*-dominated grief to a *sukha*-depthed quiet — is the same shape, and it is the shape the Lotus Simile points at.

A precision point from the source: *念身* in the *Madhyama Āgama* is *observing* the body in *無喜生樂*, not dissolving into it. In a real grief walk-through, the meditation instruction would be to *watch* the lotus-body, not to *drink* it. The lay version of this can be as simple as letting yourself sit with the cool sated feeling and noticing that you are noticing it — *有知有見, 有明有達*. The ease is what you observe; the observing is what protects you from making the ease another object of clinging.

7. The break-up / job-loss aftermath. Same shape, with a different texture: an agitation that initially has *pīti* (anger, rage-clarity, plot-spinning) eventually quiets into a resolution you can feel in your stomach and lungs. The boundary is not "I feel nothing now." The boundary is: the *buzz* is gone, the *ease* remains. Inside the meditation hall, that ease would be *聖樂*; in the office / apartment, it is the lay analog.

8. Meditation as such. Sit for an hour. The first thirty minutes: *pīti* comes and goes — pleasant itches, rushes, sudden epiphanies, body shakes. The second thirty minutes: most of those have dissolved. There is a *sukha* that has nowhere to go and nothing to demand. The lotus. The *念身* practice is sitting there *watching* the saturation while continuing to breathe. (If you then try to make the *sukha* last, you have re-introduced *pīti* — the *mind's* excitement at having *sukha* — and you have stepped back into the second *dhyāna*. The classical simile retuning is sharp: many meditators sit at second-*dhyāna* saturation and mistake it for the lotus. The true third is the *sukha* you have stopped being excited about.)

The walk-through closes with a useful summary map:

| Classical component | Contemporary *shape* | |---|---| | 初禪 *離生喜樂* (澡豆喻) | Buzzy well-being that *needs* initial setup (a class, a workout, a talk, a match) and active effort to lather | | 二禪 *定生喜樂* (山泉喻) | Bubbling joy that wells up on its own, still effervescent | | 三禪 *無喜生樂* (蓮花喻) | The effervescence settled; only *sukha*, saturating everywhere; quiet, full | | 四禪 *清淨心* | Even the *sukha* is seen through as *feeling*, the lotus lake itself becomes transparent |


Why contemporary people need this

Because the dominant pleasure economy is *pīti* economy — feed-forward, compare-and-outdo, peak-and-rebound, *pīti* economy. We have engineered our cultural infrastructure around the *喜* that the *Madhyama Āgama* calls "病本、癰本、箭刺之本," and have left almost no language for *樂*.

Three specific reasons this matters now:

1. Naming the lull. A common modern complaint is the *quiet after a fix* — the end-of-Netflix-blankness, the Monday-morning ash, the post-vacation-withdrawal. People pathologize the lull as depression when it is in fact the *pīti* discharge from the previous *pīti* event. *無喜生樂* gives you a different reading: the *pīti* has run out, and you are now in the *sukha* layer — *if* you do not reach for the next jolt. The text's "離生喜樂 / 定生喜樂 / 無喜生樂 / 清淨心" sequence is, in effect, a description of how to be a creature who no longer needs the device to get to the next stage, because the next stage is already the body you are sitting in.

**2. Distinguishing *sukha* from *pīti* makes meditation less intoxicating.** First-time meditators, and many experienced ones, often mistake *pīti*-states (the very real euphoria that can arise in the early *dhyānas*) for *sukha*. They build their practice around *pīti*-chasing, and burn out. They identify the *lotus simile* with the *spring simile*. Knowing that the early texts deliberately depict the *pīti* factor as something to be *let go of* in the transition to the third *dhyāna* — so that *sukha* can stand on its own, and even *sukha* can be let go of in the fourth *dhyāna* — is a corrective. The classical text is not flattered by *pīti*; it sees *pīti* as the parent's *rapture over the child*, beautiful but conditional, and it knows that *real* security is the room after the parent has left.

3. Making sense of a wound at the source of well-being. Modern neuroscience and modern gadget-design both know that the *pīti* system (dopaminergic, anticipatory, reward-prediction-error-driven) *is* the wound-system. Anticipation that must constantly update; wanting that never gets fed enough; the famous hedonic treadmill. *Sukha* is described in early Buddhist texts in terms that *resonate* with the slower, more homeostatic wellbeing circuitry (serotonergic tone, parasympathetic tone, endogenous opioids, social-bond systems). I want to be careful here: this is a structural analogy, not an equivalence. The early *āgama* is not a neuroscience textbook, and the third *dhyāna* is not a way to "increase serotonin." What is true is that the *pīti/sukha* distinction in classical contemplative vocabulary matches a real distinction in how the nervous system organizes wellbeing — and contemporary readers can use the classical distinction as a sanity check on which ecological/technological/cultural practices are training *pīti* at them, and which are training *sukha*.

4. Reframing the goal of rest. Most modern rest is *stimulation-switch-off*: blank-couch, doomscroll-light, screen-iridescence. *無喜生樂* reframes rest as a *positive felt state* — ease saturating the body — rather than the absence of aversive input. The lotus is not a quiet screen; it is a rooted plant in water; the ease is the medium, not the gap. Most people have no language for what they want when they want to "relax"; they reach for *pīti*-cessation, get empty boredom, and conclude they have already "rested." *Sukha-saturated rest* — the lotus — is a completely different target.


Common misreadings and clarifications

1. "No-joy pleasure" sounds contradictory and therefore must be a trick. Actually it is the most ordinary of meditative observations: the early *pīti* of the first *dhyāna* (the lather) is bright and full of itself, but *unstable*, and tends to flip into its opposite. The *sukha* of the third *dhyāna* is unhurried and *does not have to flip*. The combination "no *pīti* + *sukha*" is not a paradox; it is a state of affairs: the lather settled, the water stayed. *無喜生樂* is the most stable bodily-feeling *dhyāna* the early texts know.

**2. "*Sukha* of the third *dhyāna* is physical pleasure, just deeper."** No. The classical text explicitly classifies it on the *聖樂* side of the *凡夫樂 / 聖樂* divide: born of renunciation, "可修、可習、可廣布" — capable of being cultivated, practiced, broadcast — without feeding death-and-rebirth. It is not a magnified body pleasure; it is a *different family* of pleasure. The lotus is in water, but the lotus is not water. The felt *ease* is real *bodily*, but its source is *separation from desire*, not *fulfillment of desire*.

**3. "*Pīti* and *sukha* are basically the same word; the text is being finicky."** Almost the opposite: the text goes out of its way to use distinct words because the *transition* from one to the other is the entire content of the third *dhyāna*. If they were the same, the third *dhyāna* would not exist as a separate stage. The whole purpose of *無喜生樂* is to show you that *pīti* can drop out and the *sukha* can deepen — which is a meditation fact, not a philological one.

**4. "I can attain *無喜生樂* in ordinary life by relaxing."** In the source text, *無喜生樂* appears under the framework of *念身* — formal mindfulness-of-body practice — and is reached through the prior *dhyānas*. The shape can be *faintly recognized* in everyday moments (see the walk-through); the attainment itself is not a lay-person product. Contemporary dharma teachers are often careful about this point; the early texts are stricter. The *lotus simile* in particular implies a depth of *absorption* (the whole plant saturated) that is not present in unadorned relaxation. However, the *understanding* of what *sukha* is — that it is *not the same as pīti*, and that it is *not on the same spectrum as five-sense pleasure* — is achievable by anyone reading carefully. That understanding alone can re-shape a life.

**5. "*無喜生樂* means the practitioner feels no emotions."** No, it is a meditation-stage description of *feeling-tone* (受) — specifically *bodily* feeling-tone — at one specific stage. Outside that stage, when not sitting, the practitioner will have plenty of *喜*, plenty of *苦*, and many variations. The classical text does not say "and then they remain in it forever"; *無喜生樂* is a stage to be known, seen, seen-through, and eventually let go of, like all *dharmas*. The *Madhyama Āgama* itself ends the verse with *「受盡欣悅 ... 心不移動」* — the *exhaustion of feeling* itself becomes a gladness; even the *sukha* is allowed to complete.

6. "The earlier stages' similes (soap-pod, mountain-spring) are just decorative." They are load-bearing. Read together:

- 澡豆喻 (first *dhyāna*): *soap needs to be rubbed in water* — the *vitakka-vicāra* (applied thinking + sustained thinking) are *present*; the practitioner is making the practice happen. - 山泉喻 (second *dhyāna*): *spring wells up by itself* — *vitakka-vicāra* have quieted; *sukha-pīti* now arises *spontaneously* from the settled concentration, not from the practitioner's effort. - 蓮花喻 (third *dhyāna*): *lotus lives in water root-to-leaf* — *pīti* has gone; only *sukha*; entire plant is in the medium; no part is unsoaked.

Removing the similes leaves the stages sounding like a vague "more silent, more silent." Keeping the similes makes each stage visibly different in *kind*, not only in *degree*. The lotus cannot be the spring; the spring cannot be the soap-pod. Each simile stands for a different relation between *feeling* and *mind*.

**7. "Three *dhyāna* *sukha* is what Buddhists aim to keep forever."** No, the fourth *dhyāna* — the *清淨心* that immediately follows in the same classical sentence — is described as having *let go of sukha* also. The whole point of the four-dhyāna series is to walk meditation-factors in such a way that none of them — *vitakka-vicāra*, *pīti*, *sukha*, feeling itself in its most refined bodily form — has to be clung to. *無喜生樂* is a *beautiful way-station*. The classical text wants you to see it, savor it, and then notice that you can also see through it.

A practical note for readers who want to use the *Madhyama Āgama* vocabulary: the strongest single guard against the most common mis-mapping is to ask, *in real time*, "what am I feeling in my body right now, and is there *pīti* anywhere in it?" If yes, you are at or below the second *dhyāna* in shape. If the body is *full and steady and unexcited*, you may be looking at the lotus shape. Then the *念身* instruction comes in: *observe the body inside as body, observe the body outside as body, with knowing, with seeing, with clarity, with penetration* — 一身如身, 一味如味, 不起於我見. The body's full ease is not the goal; the *seeing* of it is.

A single closing image, faithful to the source

A lotus growing at the bottom of a clear pond, its roots in the mud, its leaves and flowers in the air, but every part of it — *root, stem, leaf, flower* — equally drenched with the water that is its element. The pond is not rushing; the water is not loud; the lotus is not excited. *Pīti* is the spring; the *lotus* is what the spring becomes when it stops rushing. *無喜生樂* is that transformation, named, in the body, in stillness, watched by mindfulness.

The *Madhyama Āgama* (T0026) places this image at the *dhyāna* sequence and at the *practice of 念身*, then — in the same breath — pushes it past itself with *受盡欣悅*. *Bliss saturating the body* is not the end of the path. It is a quiet pond, full of water, where the lotus lives. From the bank, looking down, you can see the bottom.

Canonical EntryAI-generated

一、定义与核心要义

「无喜生乐」(aprītija-sukha),为四禅次第中第三禅之身受。依《中阿含经》(《中阿含經》)之叙述,此乐生于喜受止息之后,唯有乐受普遍充满于全身,不依赖喜之伴行,故名「无喜生乐」。《中阿含经》不为此概念另设独立名相解释,而以禅次序列、莲花譬喻与圣凡二乐判摄三重笔法呈现其义。

二、主要阐述

(一)禅次序列中的定位。经文以固定句式依次铺陈四禅阶次:初禅「离生喜乐」,二禅「定生喜乐」,三禅「无喜生乐」,四禅「清净心」。无喜生乐处于喜受已灭、唯余乐受之禅定状态。经文直接描述其受用相为「渍身润泽,普遍充满于此身中,无喜生乐无处不遍」,显示此乐由内而外遍满全身之特质。

(二)莲花喻。经文为无喜生乐设一专属譬喻:「犹青莲华,红、赤、白莲,水生水长,在于水底,根茎华叶,悉渍润泽,普遍充满无处不周。」莲花自根至叶浸润于水中,喻乐受由内而外渗透全身,不假外缘。此喻与初禅之澡豆喻、二禅之山泉喻形成递进:澡豆需水和合(有作意),山泉自涌(定自生),莲花则全在水中、根茎花叶无一不渍(喜已沉没,纯乐遍体)。

(三)圣凡二乐之判摄。另一处经文将乐分为二类:「因五欲功德生喜生乐」属凡夫乐,为「病本、痈本、箭刺之本,有食有生死,不可修」;而「离欲、离恶不善之法,至得第四禅成就游」所生之乐,是「圣乐、无欲乐、离乐、息乐、正觉之乐,无食无生死,可修、可习、可广布」。无喜生乐作为第三禅之乐,在此判摄中归入圣乐一系,经文以「决定于齐,决定知已,所有内乐当求彼者」劝修。

(四)与「受尽」之关联。一偈颂云「乐在无欲,心存远离,喜于无诤,受尽欣悦。亦乐受尽,心不移动」,将无欲之乐与「受尽」并举,暗示无喜生乐已近受之寂止,心不为色声香味触所动,「犹如石山,风不能动」。

三、不同部类与译本的表述差异

本条目所依据之资料出自《中阿含经》(《中阿含經》),属阿含部。经中以「无喜生乐」为固定用语,未见与异译本之直接对照。

就本经自身之术语形式而言,修行观境用「念身」而非后世通称之「念处」或「身念处」;观身段落收束句为「观内身如身,观外身如身,立念在身,有知有见,有明有达」,不取「观身不净」等四念处定型表述。无喜生乐在此隶属「修习念身」或「观身如身」之下,是身念修习的所观境,而非独立的受念处议题。

四、与相关概念的关系

- 与初禅「离生喜乐」、二禅「定生喜乐」:三者同属色界四禅之身受,以「喜」之存灭为分界。初禅、二禅皆有喜受伴行;三禅喜受已没,独留乐受,故名「无喜」。 - 与第四禅「清净心」:四禅连乐受亦舍,与三禅之「无喜生乐」构成「离喜」与「离乐」之递进。 - 与圣乐:无喜生乐属「离欲、离恶不善之法」所生之圣乐系统,与五欲之凡夫乐形成对照。 - 与「受尽」:偈颂将「受尽」与「无欲之乐」并举,显示三禅之乐已趋向受之寂止,心不为外境所动。

五、代表性原文引用

- 「无喜生乐无处不遍」——描述乐受遍满全身之相。 - 「犹青莲华,红、赤、白莲,水生水长,在于水底,根茎华叶,悉渍润泽,普遍充满无处不周」——莲花喻。 - 「因五欲功德生喜生乐……是病本、痈本、箭刺之本,有食有生死,不可修……至得第四禅成就游……是圣乐、无欲乐、离乐、息乐、正觉之乐,无食无生死,可修、可习、可广布」——圣凡二乐判摄。 - 「乐在无欲,心存远离,喜于无诤,受尽欣悦。亦乐受尽,心不移动」——偈颂。 - 「观内身如身,观外身如身,立念在身,有知有见,有明有达」——观身收束句。

中阿含經T0026 · 阿含部

《中阿含經》以「無喜生樂」一詞指稱離喜之後所生之樂,此為該經論述第三禪身受的核心術語。經中不另立「捨念樂住」等名目,而徑以「無喜生樂」四字標舉此定境之體性——喜已離而樂猶存,樂非由喜生,乃由離喜而生。

在「念身」段落中,經文以四層遞進展開:離生喜樂、定生喜樂、無喜生樂,而後接以清淨心遍滿。無喜生樂之標準表述為:「比丘者,無喜生樂,漬身潤澤,普遍充滿於此身中,無喜生樂無處不遍。」 此處「漬身潤澤」「普遍充滿」「無處不遍」三語反覆強調此樂遍滿全身、無有遺漏,非局部之受,而是整體身中之樂。

經文所用譬喻為水生蓮華:「猶青蓮華,紅、赤、白蓮,水生水長,在於水底,根莖華葉,悉漬潤澤,普遍充滿無處不周。」 此喻取蓮華自根至葉皆浸於水中、無一處不被水潤之象,以喻無喜生樂之遍身。與前二禪之喻相較——離生喜樂喻如澡豆和水成摶、定生喜樂喻如山泉自涌——無喜生樂之喻轉為靜態之浸潤,蓮華「在於水底」,不涌不溢,唯是安住於水中而通體潤澤,正合離喜後寂靜安樂之相。

同一「無喜生樂」表述復見於「觀身如身」段落,句式全同,唯結語由「隨其身行,便知上如真」轉為「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」。 可知此樂在念身門中攝歸「知上如真」,在觀身門中則攝歸「有知有見,有明有達」之觀慧,二門所觀之樂同一,而所歸之智用有別。

經末偈頌總括此類定樂之歸趣:「樂在無欲,心存遠離,喜於無諍,受盡欣悅。亦樂受盡,心不移動,得知如真,從是心解。」 此處「樂在無欲」「亦樂受盡」與無喜生樂之「離喜」一脈相承——樂不在增益,而在減損;不在喜之添,而在喜之離。偈中復以「猶如石山,風不能動」喻心之不動, 與無喜生樂之寂靜義相表裏。

綜觀《中阿含經》所論,「無喜生樂」一語即該經對第三禪樂之定名,不假「捨」「念」等字,徑以「無喜」標其離、以「生樂」標其得,術語簡而義足。

雜阿含經T0099 · 阿含部

《雜阿含經》論述「無喜生樂」時,並未直接使用「無喜生樂」或「離喜生樂」作為固定術語,也未明言禪定次第;其核心用語是「無惱」「無有歡喜」「不樂不能壞」「無喜」「無事」「無作」「無憂」與「安樂」。因此,此經所呈現的重點,是不以歡喜為所依,而由無惱、無事、無作、無憂顯出一種不受動搖的安樂情狀。

首先,經文以「我無惱解脫,亦無有歡喜」並舉「無惱」與「無歡喜」。此處的「無有歡喜」不是被敘作缺陷,反而與「無惱解脫」相連,表示離於惱害之時,亦不須以歡喜標誌其解脫。隨後所說「不樂不能壞」,更從反面指出:即使沒有可稱為歡喜或樂著的狀態,也不能因此破壞其獨住;「故獨一而住」則刻畫出不依外緣、不因無歡喜而動搖的安住側面。

其次,此經明言「煩惱生歡喜,喜亦生煩惱」,把「煩惱」與「喜」寫成彼此相生的關係。這是此經論述中的獨特側面:它不把一切「喜」直接等同於究竟安樂,而特別警示由煩惱所生的歡喜,以及歡喜復能生起煩惱。故下句以「無惱亦無喜」概括所取的狀態;此處原文所用的是「喜」與「歡喜」,並非其他可能的「禪悅」「離生喜樂」等術語。末句「天神當護持」則表明這種無惱、無喜的情狀受到護持。

再次,經文以「無事亦得樂,無作亦無憂」補充安樂的另一面向。「樂」並非必待有事可營、有作可成而後取得;「無事」仍可得樂,「無作」亦可無憂。其後「若與我是處,令我得安樂」直接使用「安樂」一詞,顯示經文並未把「無喜」寫成枯寂或苦惱,而是把無事、無作、無憂與安樂相互連接。

綜合而言,此經以「無惱亦無喜」為最凝練的表述:一方面揭示歡喜可能與煩惱互相引生,另一方面又以「不樂不能壞」及「無事亦得樂」說明,沒有歡喜或可樂之事,並不妨礙安住與得樂。其所記錄的用詞特色,正是以「無惱」「無喜」「無事」「無作」「無憂」描述離於擾動的條件,以「樂」「安樂」「獨一而住」描述其結果;原文並未另立明確的定名,亦未交代此境在禪定階位中的位置。
