這個概念在說什麼

In early Buddhist thought, "Joy and Pleasure" (喜樂, *prīti-sukha*) is not a superficial state of cheerful excitement, nor is it a luxury reserved for casual relaxation. It is a precise, structural engine at the heart of the path to liberation (解脫道, *mokṣa-mārga*).

To understand *prīti-sukha*, we must first resist collapsing two distinct Pali/Sanskrit terms into a single vague word like "happiness." Early Buddhist texts rigorously distinguish between Joy/Rapture (喜, *prīti*) and Bliss/Pleasure (樂, *sukha*):

1. ***Prīti* (喜, Joy / Rapture): Psychologically classified under the Aggregate of Volitional Formations** (行蘊, *saṅkhāra-kkhandha*), *prīti* is an invigorating, refreshing, and mental-bodily exhilaration. It is the initial "spark" or surge of spiritual enthusiasm that uplifts the mind when it breaks free from unwholesome states. 2. ***Sukha* (樂, Bliss / Tranquil Pleasure): Classified under the Aggregate of Feeling** (受蘊, *vedanā-kkhandha*), *sukha* is a calm, deep, soothing, and abiding sense of well-being. It is the quiet ocean of contentment that settles in once the initial surge of *prīti* calms down.

The classic ancient illustration (often found in commentarial literature like the *Visuddhimagga*) brings this difference to life: Imagine a traveler exhausted and parched in a hot desert. When he first spots an oasis or hears about a cool pond ahead, he experiences ***prīti* (喜)—an exhilarating surge of hope, excitement, and refreshing delight. When he actually steps into the shade, drinks the clear water, and bathes in the cool stream, he experiences *sukha* (樂)**—the soothing, tranquil, and embodied sense of bliss.


1. The Causal Chain: From Morality to Concentration

In the *Madhyama Āgama* (*Middle Length Discourses*, 中阿含經), the emergence of *prīti-sukha* is mapped out not as a random stroke of good luck, but as a clear, organic domino effect of spiritual cause and effect:

$$\text{Pure Conduct / Ethics (持戒)} \rightarrow \text{Non-Remorse (不悔)} \rightarrow \text{Gladness (歡悅, } pāmojja\text{)} \rightarrow \text{Rapture (喜, } prīti\text{)} \rightarrow \text{Tranquility (止/輕安, } passaddhi\text{)} \rightarrow \text{Bliss (樂, } sukha\text{)} \rightarrow \text{Concentration (定, } samādhi\text{)}$$

* **Pure Conduct / Ethics (持戒, *śīla*)**:Living with integrity creates a mind free from guilt, fear, and self-reproach. * **Non-Remorse (不悔, *avippatisāra*)**: The immediate result of clean living is an unburdened conscience. * **Gladness (歡悅, *pāmojja*)**: A subtle, gentle brightness of mind that arises from a clean conscience. * **Rapture (喜, *prīti*)**: As gladness builds, it erupts into an invigorating spiritual joy (*prīti*), refreshing the mind and body. * **Tranquility (止, *passaddhi*)**: The exhilarating energy of *prīti* cools down and relaxes physical and mental restlessness. * **Bliss (樂, *sukha*)**: Resting in deep tranquility gives rise to an unshakeable, embodied feeling of ease (*sukha*). * **Concentration (定, *samādhi*)**: Supported by this profound ease—because a happy, relaxed mind does not wander—the mind effortlessly settles into deep concentration.


2. The Four Meditative Absorptions (*Dhyānas*) and "Present-Body Bliss"

In the *Dīrgha Āgama* (*Long Discourses*, 長阿含經) and *Madhyama Āgama*, the refined experience of *prīti-sukha* within meditative absorption (禪定, *dhyāna* / *jhāna*) is described as "experiencing bliss directly in the present body" (現身得樂). Rather than an abstract, otherworldly promise, it is a tangible physical and mental saturation:

* **First *Dhyāna*: "Joy and Bliss Born of Seclusion" (離生喜樂, *vivikta-ja-prīti-sukha*)** * *Nature*: Arises from withdrawing (*離*) from sense-desires and unwholesome thoughts. * *Canonical Imagery*: Like a bath attendant mixing soap powder with water until the moisture thoroughly marinates every grain—joy and bliss pervade every cell of the physical body. * **Second *Dhyāna*: "Joy and Bliss Born of Concentration" (定生喜樂, *samādhi-ja-prīti-sukha*)** * *Nature*: Initial thought-directed activity (覺/觀, *vitakka-vicāra*) subsides. Inner tranquility and single-pointedness unleash a deeper level of joy and bliss (*定生喜樂*). * *Canonical Imagery*: Like a cool, subterranean spring surging from the bottom of a lake, filling the water from within without needing rain from above. * **Third *Dhyāna*: "Bliss Dwelling with Equanimity" (離喜住樂 / 捨念樂住, *niṣprīti-sukha*)** * *Nature*: The mind transcends even the uplifting excitement of *prīti* (離喜). What remains is pure physical and mental bliss (*身覺樂*), guarded by mindfulness and equanimity. * *Canonical Imagery*: Like lotus plants submerged underwater—from root to tip, completely soaked, bathed, and drenched in cool water without breaking the surface. * **Fourth *Dhyāna*: "Purity of Equanimity and Mindfulness" (不苦不樂 / 捨念清淨, *upekṣā-smṛti-pariśuddhi*)** * *Nature*: The subtle mental movement of bliss (*sukha*) is finally laid to rest alongside pain and sorrow. The mind enters an unmoving (不移動), non-dual state of immaculate stillness. * *Canonical Imagery*: Like a person sitting wrapped from head to toe in a clean white cloth—completely enveloped in pure, unblemished clarity.

In the *Madhyama Āgama*, the Buddha presents a crucial nuance: even though the joy and bliss of the First, Second, and Third *Dhyānas* are exalted, noble states, from the ultimate vantage point of a Noble One (聖者, *āriya*), they are still classified as "moving / fluctuating" (移動). Why? Because *prīti* and *sukha* still involve subtle emotional activity. Only when the mind reaches the Fourth *Dhyāna*—transcending both pleasure and pain into unshakeable equanimity—does it achieve true "immobility" (不移動).


3. Worldly Pleasure vs. Noble Bliss

Early Buddhist texts strictly separate happiness into two fundamentally different categories:

| Dimension | Worldly Sensuous Pleasure (凡夫樂 / 非聖樂 / 有食樂) | Noble Spiritual Bliss (聖樂 / 無欲樂 / 離樂 / 息樂) | | :--- | :--- | :--- | | Origin | Derived from the five sense objects (五欲功德: sight, sound, smell, taste, touch) and worldly attachments. | Derived from renunciation, seclusion from craving, and meditative absorption (*dhyāna*). | | Nature | Combative & Contaminated (有穢惡刀杖、鬪訟喜樂): Driven by competition, territoriality, and fear of loss (e.g., world victory in battle). | Peaceful & Non-combative (無有刀杖、諍訟之樂): Completely free from conflict, friction, or hostility. | | Canonical Simile | "Lighting a fire with wet wood and brush" (因草木而然火): Generates thick smoke, causes irritation, requires constant fueling, and quickly burns out. | "Lighting a fire without wood or brush" (離草木而然火): An unconditioned, smokeless, self-sustaining illumination born of inner freedom. | | Diagnosis | Called "a disease, a boil, a dart in the chest" (病本、癰本、箭刺之本). It keeps the mind tethered to suffering and samsara (*有生死樂*). | Called "bliss of liberation, bliss of peaceful cessation" (息樂、正覺之樂, 得離貪欲樂). It frees the mind (*無生死樂*). |


4. The Sensory Contact Mechanism (*Ṣaḍ-āyatana*)

Beyond meditative absorptions, the *Saṃyutta Āgama* (*Connected Discourses*, 雜阿含經) acknowledges that joy and bliss can also occur through the Six Sense Bases (六觸入處, *ṣaḍ-āyatana*: eye, ear, nose, tongue, body, and mind). When sense organs encounter pleasant, wholesome, and non-afflictive conditions (*可愛、可念、善良之事*), agreeable feelings arise.

However, early Buddhism clarifies that while wholesome sensory contact offers temporary comfort, relying on external objects for joy makes one a prisoner of circumstances. True, unshakeable bliss (*常致喜樂*) is only secured when the mind breaks through the nets of craving—"like a fish breaking through a net, never returning to the water" (如魚決其網,不復入於水)—and abides effortlessly in concentration and insight.


生活裡的走查

To understand how *prīti-sukha* operates—and where contemporary urbanites frequently misunderstand it—let us walk through a typical modern day.

``` [Daily Scenario] 07:30 AM Morning Scroll in Bed ➜ Mistaking "Dopamine Thrill" for Sukha 10:00 AM Aggressive Work Competition ➜ "Combative Pleasure" (有鬪訟喜樂) 03:00 PM Overcoming a Crisis Cleanly ➜ Clean Conscience & Gladness (不悔 ➔ 歡悅) 08:00 PM Deep Focus / Meditation ➜ Seclusion-born Joy & Bliss (離生喜樂) ```

Step 1: 07:30 AM — The Morning Doomscroll

You wake up and immediately grab your smartphone. You swipe through short video algorithms, notifications, and breaking news. You feel a sudden surge of excitement, a chuckle, or an intoxicating hit of novelty.

* The Mappings & Error: Modern readers often confuse this sensory stimulus with *joy* or *happiness*. In Buddhist taxonomy, this is purely Worldly Sensuous Pleasure born of the Six Sense Bases (六觸入處五欲樂). It relies entirely on external inputs. Notice what follows immediately after: a subtle restlessness, eye strain, and a mental fog. It is precisely what the *Madhyama Āgama* calls "lighting a fire with wet wood" (因草木而然火)—it produces more smoke (agitation) than actual warmth, leaving behind a subtle burn (*病本、箭刺之本*).

Step 2: 10:00 AM — Winning the Workplace Pitch

You successfully outperform a rival team in a major corporate presentation. You feel an intense rush of triumph and pride.

* The Mappings & Error: You might say, "I am so happy today!" But examine the quality of this feeling. It is built upon comparison, territoriality, and the defeat of others. The *Dīrgha Āgama* compares this directly to King Śakra's victory over the Asuras: it is "pleasure accompanied by weapons, hostility, and strife" (有穢惡刀杖喜樂、鬪訟喜樂). Because it depends on staying "on top," it brings an undercurrent of anxiety: *What if we lose the next quarter?*

Step 3: 03:00 PM — Choosing Integrity Over a Shortcut

During a stressful project, you are tempted to shift blame onto a colleague to save face. Instead, you take responsibility, speak truthfully, and handle the issue cleanly.

* The Mappings & Error: Here, the sequence of *śīla* (持戒) begins to play out. Because you acted with integrity, no latent anxiety or guilt plagues your mind—this is Non-Remorse (不悔). As you sit at your desk, a gentle, light feeling washes over you—this is Gladness (歡悅, *pāmojja*). It isn't an explosive thrill, but an unburdened lightness of heart.

Step 4: 08:00 PM — Turning Off Devices and Sitting Quietly

In the evening, you turn off your phone, close your laptop, and sit quietly in room seclusion. You let go of the day's ambitions and regrets.

* The Mappings: 1. **Seclusion (*離*): As you put down sensory cravings, the mind experiences a break from constant stimulation. 2. Rapture (*喜*, *prīti*)**: A subtle, tingling warmth or upward surge of vitality fills your chest and torso—this is the refreshing spark of *prīti*. 3. **Tranquility & Bliss (*止* & *樂*, *passaddhi* & *sukha*)**: As *prīti* settles, your breathing grows imperceptibly smooth, your muscles melt open, and a deep, delicious sense of physical ease permeates your body. This is "experiencing bliss directly in the present body" (現身得樂). 4. **Concentration (*定*, *samādhi*)**: Because your body and mind are thoroughly satisfied, your mind no longer hungers to scroll, shop, or plot. It comes to a natural, effortless rest on a single point.


當代人為什麼需要它

1. Escaping the "Dopamine Treadmill" Modern life is engineered by hyper-optimized attention economies designed to trigger rapid dopamine spikes. Contemporary neurobiology distinguishes between dopamine (the drive of anticipation, desire, and "wanting") and serotonin/endorphins (the neurochemical correlates of satisfaction, ease, and "liking/contentment"). When modern people chase endless sensory hits, they remain in a chronic state of "wanting" that never settles into "satisfaction." Early Buddhism identified this millennia ago: worldly pleasure (*凡夫樂*) is an itchy rash that demands constant scratching. The concept of Spiritual Bliss (聖樂 / 無欲樂) provides a radically alternative model of happiness—one that is generated by subtraction (letting go, seclusion) rather than addition (consuming, acquiring).

2. Therapeutic Integration of Mind and Body Many contemporary mental health challenges—such as chronic anxiety, burnout, and somatic tension—stem from a severe disconnect between a hyperactive mind and an exhausted body. The canonical insistence on "experiencing bliss in the present body" (現身得樂) reminds us that genuine spiritual transformation is not an abstract intellectual exercise. Authentic meditative joy (*prīti-sukha*) physically saturates the nervous system, undoing deep-seated somatic tension and restoring wholeness.

3. A Pragmatic Bridge to Deep Focus In an age of fragmented attention, people try to force focus through sheer willpower or anxiety. Early Buddhist psychology reveals a far more effective law of mind: "Bliss leads to Concentration" (因樂便得定). You cannot force a distressed, restless mind into deep focus; but a mind that is thoroughly relaxed, tranquilized, and enjoying inner bliss settles into concentration naturally.

*Note on Scientific Analogies*: While modern neuroscience (such as neurochemical tracking or fMRI brain scans of meditators) offers helpful physical analogies for the physiological correlates of tranquility, science measures bodily mechanics. Early Buddhist *prīti-sukha* is an intentional, ethically rooted, and introspective cultivation aimed at eradicating the root causes of suffering (*kleśas*). Science describes the physical shadow; the Dharma provides the pathway to mental liberation.


常見誤讀與澄清

誤讀一:把「喜」(Prīti)與「樂」(Sukha)當作同義詞混為一談

* Clarification: In everyday language, "joy" and "pleasure" are used interchangeably. But in classical Buddhist phenomenology, they belong to different mental categories and function differently along the path: * **喜 (*Prīti*)**: Belongs to the Aggregate of Volitional Formations (行蘊). It is energizing, uplifting, coarse, and invigorating. * **樂 (*Sukha*)**: Belongs to the Aggregate of Feeling (受蘊). It is tranquil, soothing, subtle, and stable. As meditation deepens from the Second to the Third *Dhyāna*, the coarse excitement of *prīti* is intentionally relinquished so that the deeper, unshakeable quietude of *sukha* can fully manifest.

誤讀二:認為佛法講「苦」,所以排斥快樂、主張苦行

* Clarification: This is one of the most widespread misunderstandings of Buddhism. The Buddha explicitly rejected painful asceticism (苦行) as useless and non-conducive to enlightenment. The classical causal chain explicitly states that without Gladness (歡悅), Joy (喜), and Bliss (樂), genuine Concentration (定) cannot arise. The Buddha did not condemn pleasure per se; he merely warned against *worldly sensuous pleasure* (凡夫樂) because of its hidden friction, transience, and combative nature. Noble spiritual bliss (聖樂) is an essential, highly praised fuel on the path to liberation.

誤讀三:把禪定中的「喜樂」當作終極解脫(悟境)

* Clarification: Because meditative joy and bliss are so profound, meditators often mistake them for final enlightenment (*Nirvāṇa*). Early scriptures issue a clear warning: in the *Madhyama Āgama*, even the highest meditative bliss of the Third *Dhyāna* (捨念樂住) is still categorized by Noble Ones as "moving / fluctuating" (移動). If a practitioner clings to *prīti-sukha*, it becomes a golden cage. True liberation requires moving past even the finest bliss into the unshakeable, non-dual equanimity of the Fourth *Dhyāna* (不苦不樂、捨念清淨) and developing insight into the impermanent, non-self nature of all conditioned states.

誤讀四:認為「離欲樂」(Bliss of Renunciation)是枯燥無味的自我壓抑

* Clarification: People often assume that letting go of sense pleasures (sensory indulgence, excessive social media, unhealthy cravings) means entering a bleak, dry, joyless void. The scriptures use the powerful simile of "lighting a fire without wood" (離草木而然火) to refute this. Worldly pleasure is like a smoky fire fed by damp wood—it hurts the eyes and burns out quickly. "Bliss of Renunciation" (得離貪欲樂) is not the absence of joy, but the discovery of a smokeless, radiant, self-sustaining light within that does not depend on external fueling.

Canonical EntryAI-generated

一、定义与核心要义

「喜乐」(prīti-sukha)在阿含部经典中,主要指修行者在禅定修持、远离贪欲、欣乐佛法,或在特定优质因缘接触下,所产生的身心愉悦、安乐与清净体验。它既是持戒修行的自然成果,也是禅定由浅入深、逐层演变的身心浸润状态。佛法将其严格区分为世俗有争斗、有染污的喜乐,与出世间无欲、清净的圣乐,并引导修行者最终超越一切喜乐的动摇,达到不苦不乐的清净解脱。

二、主要阐述

1. 禅定修行中的身心浸润与逐层演变 在禅定修持中,「喜乐」呈现出由浅入深、逐层演变的特征。根据《长阿含经》,比丘在修习四禅时,身心被喜乐所润渍与充满,称为「现身得乐」。初禅时「喜乐遍身,无不充满」,中外俱润,为「最初现身得乐」;二禅时因除灭觉观而产生「定生喜乐」,「一心喜乐润渍于身,周遍盈溢」,为「第二现身得乐」;三禅时「离喜、住乐」,「身无喜,以乐润渍」,为「第三现身得乐」;四禅时虽「不苦不乐」,但仍表现为「身心清净,具满盈溢」,被称为「第四现身得乐」与「安隐快乐」。 《中阿含经》则从「移动」(动摇)与否的角度深化了这一演变:初禅的「离生喜乐」、二禅的「定生喜乐」、三禅的「舍、念、乐住」,在圣者看来,其「喜」与「心乐」仍属于「移动」状态;唯有到了第四禅,乐灭苦灭、忧喜先除,达到「不苦不乐、舍、念、清净」,才被称为「不移动」。 《杂阿含经》亦强调,修行者如鱼决网到达彼岸,若能「禅定具足住」,其心灵便能「常致喜乐」,表明禅定是产生持续喜乐的关键。

2. 世俗五欲喜乐与出世间清净法乐的对比 经典对世俗之乐与出世间之乐进行了严格的区分。根据《长阿含经》,帝释天过去与阿修罗战斗获胜所得的「喜乐、念乐」,被斥为「有秽恶刀杖喜乐、鬪讼喜乐」,伴随着暴力与争斗;而其在佛陀处所得的则是「无有刀杖、诤讼之乐」的清净法乐。 《中阿含经》将因「五欲功德」所生的喜乐称为「凡夫乐」(非圣乐),斥之为「病本、痈本、箭刺之本」,是有食、有生死的,不可修习,并以「因草木而然火」为喻,说明依凭欲与恶不善法无法获得真正的止息。相反,因离欲、离恶不善法及成就禅定所生的喜乐被称为「圣乐」(无欲乐、离乐、息乐、正觉之乐),是无食、无生死的,可修可习,喻为「离草木而然火」。此外,经中亦提到「乐在无欲,心存远离,喜于无诤」的解脱欣悦。 《杂阿含经》则指出,对佛法的向往(「欣乐」大仙法)与摆脱贪欲(「得离贪欲乐」)本身就是极大的清净快乐。

3. 感官接触与喜乐的产生机制 除了禅定与离欲之乐,《杂阿含经》还从感官与环境接触的角度探讨了喜乐。在特定的优越界域中,众生因其眼、耳、鼻、舌、身、意等「六触入处」所接触的外境皆为可爱、可念、善良的事物(如眼见可爱色、不见不可爱色等),在这些因缘具足下,得以「一向长受喜乐」。这展示了喜乐的体验与感官接触性质的直接关联。

三、不同部类与译本的表述差异

在不同经典中,关于「喜乐」的术语形式与表达风格存在显著差异: 1. 禅定喜乐的术语: * 《长阿含经》特以「现身得乐」指代四种禅定状态下现世肉身所直接体验到的喜乐;并用「定生喜、乐」指称二禅,用「离喜、住乐」或「舍喜……自知身乐」指称三禅。 * 《中阿含经》则将初禅之乐表述为「离生喜、乐」;二禅表述为「定生喜、乐」;三禅表述为「舍、念、乐住」或「身觉乐」;四禅表述为「不苦不乐、舍、念、清净」。 2. 世俗与出世间乐的称法: * 《长阿含经》在帝释天的对话中,常将「喜乐」与「念乐」并提;并将修习「慈、悲、喜、舍」四无量心(含「喜心」)自娱乐的状态,独特地称之为「比丘财宝丰饶」。 * 《中阿含经》将世俗乐称为「凡夫乐」、「非圣乐」;将出世间乐称为「圣乐」、「无欲乐」、「离乐」、「息乐」、「正觉之乐」,并有「乐在无欲,心存远离,喜于无诤」之说。 * 《杂阿含经》则使用「欣乐」与「得离贪欲乐」来描绘对佛法的欢喜与断除烦恼的体验。 3. 译经风格与特定名词: * 《杂阿含经》展现了独特的译经风格,如使用「大仙」尊称佛陀,将佛法称为「大仙法」;在描述感官媒介时使用「六触入处」及「眼声、鼻香、舌味、身触、意所识法」等术语;在描述禅定成就时使用「禅定具足住」。

四、与相关概念的关系

1. 与「持戒」、「不悔」、「欢悦」、「止」、「定」的因果关系: 《中阿含经》详细梳理了喜乐在修行次第中的位置:因持戒而得「不悔」,因不悔得「欢悦」,因欢悦得「喜」,因喜得「止」(止身),因止得「乐」(觉乐),因乐得「定」(定心)。在此链条中,「喜」能令身心止息,而「止」能令人觉知「乐」,「乐」则能进一步令心安住于禅定。 2. 与「四无量心」的关系: 《长阿含经》中,比丘修习「慈、悲、喜、舍」四无量心,其中的「喜心」被视为比丘自娱乐的「财宝丰饶」。 3. 与「六触入处」的关系: 《杂阿含经》指出,喜乐的产生与「六触入处」接触的外境性质密切相关。当眼、耳、鼻、舌、身、意接触到可爱、可念、善良的事物时,便会「一向长受喜乐」。

五、代表性原文引用

1. 《长阿含经》:「比丘以无参、无观,内信、欢悦,心专一,无参、无观,定生喜、乐,第二现身得乐。……比丘离喜、住舍、自知身乐,贤圣所说护、念、乐住,第三现身得乐。」 2. 《长阿含经》:「彼往昔时与阿须轮战,阿须轮退,诸天得胜。我于尔时,战胜之后,生喜乐、念乐。然彼喜乐、念乐,有秽恶刀杖喜乐、鬪讼喜乐,非是寂灭,非是走向泥洹。我今于佛所,得喜乐、念乐,无有刀杖、诤讼之乐。」 3. 《中阿含经》:「因持戒便得不悔,因不悔便得欢悦,因欢悦便得喜,因喜便得止,因止便得乐,因乐便得定。」 4. 《中阿含经》:「若有乐五欲功德,因五欲功德生喜乐,此乐非圣乐,是凡夫乐、是有食乐、是有生死乐,不可修、不可习、不可多实……若有离欲、离恶不善之法,至成就四禅,因是生喜乐,此乐是圣乐、是无欲乐、是离乐、是息乐、是正觉之乐,可修、可习、可广布。」 5. 《杂阿含经》:「如鱼决其网,不复入于水,禅定具足住,其心常致喜乐。」 6. 《杂阿含经》:「我今甚欣乐,大仙法之上,得离贪欲乐,不复乐世间。」

長阿含經T0001 · 阿含部

【《長阿含經》對「喜樂」之論述】

《長阿含經》中,「喜樂」一詞主要於論述四禪的脈絡下出現,作為禪定中由定所生、現身受用的身心境界。本經論述此概念有以下數項要點:

一、四禪中的喜樂階位。本經將喜樂安置於四種禪定境界之中,呈現由淺入深的階位差別。初禪階段「喜樂遍身,無不充滿」,以「人巧浴器盛眾藥,以水漬之,中外俱潤,無不周遍」為喻,形容喜樂如藥水內外浸透全身。第二禪「定生喜、樂」,「一心喜樂潤漬於身」,喻如山頂涼泉自中出,清淨水自浸其池,周遍無遺。第三禪則「捨喜、住,護念不錯亂,身受快樂,如聖所說,起護念樂」,此時「身無喜,以樂潤漬」,猶如優鉢、鉢頭摩、拘頭摩、分陀利等花「始出淤泥而未出水,根莖枝葉潤漬水中,無不周遍」。第四禪「捨喜、樂,憂、喜先滅,不苦不樂,護念清淨」,以「沐浴清潔,以新白疊被覆其身,舉體清淨」及密室燃燈、火焰不動為喻,顯示喜樂俱捨、心無增減傾動之境。

二、喜與樂的分別。本經在描述四禪時,明確區分「喜」與「樂」二字,並非始終並稱。初禪與第二禪「定生喜、樂」,喜與樂並存;第三禪「捨喜、住樂」,已無喜而唯有樂潤漬其身;第四禪更進一步「捨喜、樂」,連樂亦捨,達不苦不樂之清淨護念。此一「喜」先離而「樂」後捨的次第,為本經論述喜樂概念的獨特脈絡,可見喜偏於心之欣喜踊躍,樂偏於身之安隱受用。

三、現身得樂之強調。本經在每禪描述之後,皆明示「是為……現身得樂」,並歸結於「斯由精進,念無錯亂,樂靜閑居之所得」,強調喜樂並非來世之果,而是於現前禪定身心中即可證得。此表述凸顯本經將喜樂定位為「現法樂住」之性質。

四、喜樂與世俗之樂的對比。除禪定外,本經亦透過帝釋之語,區隔禪定所得之喜樂與世俗鬪訟之喜樂。帝釋憶昔與阿須輪共戰得勝之「歡喜、念樂」,自計「離有穢惡刀杖喜樂、鬪訟喜樂」;而「今我於佛所得喜、念樂,無有刀杖、諍訟之樂」。此處出現「念樂」一詞,指伴隨正念之喜樂,與世俗戰鬥之喜樂形成鮮明對比,凸顯本經對喜樂內涵之清淨性與無諍性的重視。

五、用語形式。本經使用「喜樂」、「喜、樂」、「喜」、「樂」等詞彙,其中「喜樂」二字連用最為常見,與本條目之概念名稱相符;亦見「念樂」、「護念、樂行」、「定生喜、樂」等複合表述,顯示「喜樂」在本經中既有合併連用,亦有分別使用之情況。

中阿含經T0026 · 阿含部

《中阿含經》對「喜樂」之論述,可從兩個層面觀察。

第一,以火為喻辨所依不同。世尊對鸚鵡摩納說:眾生依五欲功德所生之喜樂,如「因草木而然火」,「不得捨樂及於止息」;若「離草木而然火」,喻眾生依離欲、從諸善法而得之「捨樂」,乃「得捨樂及於止息」,其光焰「最上、最妙、最勝」。此處以欲、惡不善之法為所依之喜樂,是有所攀緣、有所繫著;離欲之喜樂則趨向止息、安穩。本段經文以「喜樂」與「捨樂」對舉,前者依欲界五欲而不得止息,後者從離欲善法而得止息,是本經區分喜樂深淺之關鍵術語。

第二,於四禪中細辨喜、樂之淺深階位。世尊先標舉五種樂——聖樂、無欲樂、離樂、息樂、正覺之樂,並明其特質為「無食、無生死,可修、可習、可廣布」,指示此樂可於第四禪成就中修習。次依四禪次第說明:初禪「離生喜、樂」;二禪「定生喜、樂」;三禪「捨無求遊,正念正智而身覺樂,謂聖所說、聖所捨、念、樂住室」;四禪「樂滅、苦滅,喜、憂本已滅,不苦不樂、捨、念、清淨」。

此段最具特色者,在於「聖說移動」與「聖說不移動」之判準。文中明言:初禪有覺觀故為移動,二禪有喜故為移動,三禪有樂故為移動;唯第四禪喜、憂本已滅,方為「聖說不移動」。又言初禪、二禪、三禪「我說此不得無、不得斷」,必以前前為「過度」而進至後後。即喜與樂雖為禪定之善境界,仍屬心行遷流;須至第四禪捨、念清淨,喜、憂俱盡,方稱究竟寂止。

合而觀之,《中阿含經》「喜」「樂」二字並用時,泛指依止禪定所生之欣喜與安適;單言「樂」則有時與「喜」對分淺深,如二禪「定生喜、樂」中先喜後樂;至四禪位,則以「不苦不樂」代換之。本經又以「喜樂」與「捨樂」、「聖說移動」與「聖說不移動」等對舉,提示離欲之喜樂乃趨向止息、可修可習之正法,而有喜有樂之心行猶屬遷變,未至不動。

一、以禪定具足為喜樂所依 本經以偈頌云:「彼當到彼岸,如魚決其網,禪定具足住,心常致喜樂。」此處將「喜樂」與「禪定具足住」直接連結,描述行者以禪定之力斷除繫縛(喻如魚決其網),究竟至彼岸後,心恆常致於喜樂。所謂「心常致喜樂」,明示喜樂非偶發之受,而是以禪定為所依、恆時安住之身心境界,與本概念所指「禪定中欣喜與安樂的身心感受」正相契合。

二、以六觸入處對顯喜樂之因緣 本經復以長行述及六觸入處之兩分果報:一者地獄眾生,眼見不可愛、不可念、不善之色,乃至意觸不可愛、不可念、不善之法,「以是因緣故,一向受憂苦」;另一分六觸入處中,眼見可愛、可念、善之色,乃至意所識法皆「可愛非不可愛、可念非不可念、見善非不善」,「以是因緣故,一向長受喜樂」。此段將喜樂置於六觸入處之對比架構中,與憂苦對舉,凸顯喜樂之生起繫於所觸境界之性質——以可愛、可念、善之境為因,感得長時喜樂之果。此與上文「禪定具足」之修證面並存,顯示本經所論喜樂兼具修證所成與因緣所生兩重意涵。

三、術語形式 本經一律以「喜樂」二字連稱,未見「喜」、「樂」分說,亦未使用「喜悅」、「安樂」、「歡喜」等替名,更未見後世唯識等系所立喜、樂之別(七作意等細分)。框架用語則維持「六觸入處」之原始譯名,未改用「六處」等其他部派異名;描述所觸之境,則以「可愛」、「可念」、「善」三分並列,作為引生喜樂之境性標幟。

四、獨特側面 本經論喜樂之特點,在於將「禪定具足住」之修證成就與「六觸入處」之因緣受用並列呈現:一面以禪定斷網為喜樂之因,一面以善淨境界觸入為長受喜樂之緣。二處用語一致而側面互補,呈現早期阿含對喜樂之多面理解:既可是禪定中心之恆常安住,亦可是六處善境觸入時之身心受用。
