Here is a deep, comprehensive exploration of the concept of the Third Dhyana, written for a contemporary reader.


What this concept is about (这个概念在说什么)

To understand the Third Dhyana (第三禪, *di san chan*), we must first look at where we have just come from on the meditative path. In the Buddhist framework of the Form Realm (色界, *rupa-dhatu*), the Second Dhyana is characterized by a profound, surging, and uplifting mental joy or rapture known as *xi* (喜, Pali: *piti*). It is an exhilarating state, free from discursive thinking. However, as the practitioner's mind becomes more refined, this very exhilaration begins to feel exhausting. The Buddha vividly described the rapture of the Second Dhyana as a "thorn" (喜为刺)—a subtle agitation that disturbs the ultimate stillness of the mind.

The Third Dhyana is the necessary evolutionary step where the practitioner transcends this mental high. The canonical texts define the Third Dhyana through a very precise sequence of psychological and physical transformations:

1. **Abandoning Rapture (离喜, *li xi*): The practitioner actively lets go of the bubbling excitement and emotional surging of the previous stage. 2. Equanimity (舍, *she*): A state of supreme, frictionless balance. The mind no longer leans toward the excitement nor pushes it away; it rests perfectly in the center. 3. Right Mindfulness (正念, *zheng nian*) and Right Clear Comprehension/Wisdom (正智, *zheng zhi*): Because the pleasure of the Third Dhyana is so profoundly sweet, the mind requires the heavy anchors of continuous mindfulness and crystal-clear lucidity to keep from being intoxicated or swept away by it. 4. Bodily Bliss (身受乐, *shen shou le*):** With the mental agitation of rapture gone, a deeply nourishing, tranquil physical bliss (*sukha*) arises. The canonical texts call this the pleasure "praised by the noble ones" (贤圣所求).

To convey how this feels, the ancient sutras do not rely on vague poetry; they use highly specific, structural metaphors that map one-to-one onto the meditator’s experience:

* The Submerged Lotus (水底莲华): Imagine a blue, red, or white lotus growing in a spring-fed pond. The crucial detail here is that *the lotus has not yet broken the surface of the water*. Its roots, stems, and petals are completely submerged, soaking continuously in the cool, still water. This perfectly maps to the experience of *shen shou le* (bodily bliss). Without breaking the surface (where the "wind" of mental agitation could strike it), the meditator's physical body is entirely permeated, saturated, and suffused with cool, tranquil bliss. * The Still Lake (山泉湖水): The mind is compared to a pristine mountain lake with clear, perfectly level shores and absolutely no waves. Yet, the texts warn that if one leaves this state and engages in idle chatter (e.g., mingling and talking with laypeople), the "wind" of worldly desire blows, whipping up waves and causing a regression. * Stockpiling Beans in a Border City (边城积豆): The Third Dhyana acts as a strategic defense. Just as a frontier king stockpiles large and small beans to ensure his city can withstand a siege, the practitioner uses the stable bliss and equanimity of the Third Dhyana to fortress the mind against the invasions of afflictions.

It is a monumental achievement, acting as the critical bridge between the joy of the earlier stages and the absolute neutrality of the Fourth Dhyana.

Walkthrough in daily life (生活里的走查)

To truly grasp the mechanics of the Third Dhyana, let us map its components onto a familiar contemporary experience, strictly following the canonical definitions.

Imagine you have been working on a massive, high-stakes project for months. Finally, it launches perfectly. Your boss praises you, your peers applaud you, and you get a life-changing promotion. * The "Xi" (Rapture) Phase: For the first three days, your heart is racing. You can hardly sleep. You want to call everyone you know. You feel high. This is the equivalent of the Second Dhyana. But by day four, you are physically exhausted. The adrenaline and excitement are actually keeping you from resting. The joy has literally become a "thorn" (喜为刺). * Step 1: Abandoning Rapture (离喜). You decide to turn off your phone. You cancel your weekend celebration plans. You consciously withdraw your attention from the intoxicating storyline of "my great success." * Step 2: Entering Equanimity (舍). You sit on your living room sofa in the quiet of a Saturday morning. You feel a profound sense of "okay-ness." You aren't suppressing the good news, but you aren't feeding it anymore. You are perfectly balanced. * Step 3: Mindfulness & Clear Comprehension (正念正智). As you sit there, the quiet feels incredibly sweet. *Zheng nian* (Mindfulness) keeps you anchored on the sofa, breathing. *Zheng zhi* (Clear Comprehension) is the quiet inner watchdog that notices: "Ah, I am experiencing peace. But if I pick up my phone to post on social media about how peaceful I am, the 'wind' will blow, the 'lake' will churn, and I will lose this." You stay lucid. * Step 4: Bodily Bliss (身受乐). Because your mind has stopped frantically jumping, your nervous system finally down-regulates. A wave of cool, restorative comfort washes through your tired muscles, from your head to your toes. You don't have a giant grin on your face, but every cell in your body feels like the submerged lotus—soaked in quiet, frictionless relief.

Pointing out the common mapping errors: When modern people hear "Equanimity" (舍), they often map it to "apathy," "numbness," or "zoning out"—like scrolling mindlessly through short videos to numb the brain after a long commute. This is a severe misunderstanding. In the Third Dhyana, *she* (equanimity) is intensely alive and is directly paired with pervasive *physical pleasure* (身受乐) and *lucid wisdom* (正智). Zoning out is dullness; the Third Dhyana is crystal clear, ultra-sensitive, yet utterly unshakeable. Furthermore, "Clear Comprehension" (正智) does not mean "thinking analytical thoughts about your state." It is non-verbal, real-time situational awareness.

Why modern people need it (当代人为什么需要它)

We live in an era structurally designed to keep us trapped in "Xi" (rapture/agitation) or craving it. The contemporary attention economy—driven by algorithms, endless scrolling, breaking news, and viral outrage/triumph—is essentially a machine built to spike our dopamine.

We can borrow a loose analogy from contemporary neuroscience. When we experience constant high-arousal spikes (dopamine rushes from notifications, likes, or fast-paced entertainment), our biological baseline drops. When the spike ends, we feel depleted, anxious, and bored. While neuroscience and Buddhism are entirely different paradigms with different ultimate goals, this biological reality mirrors the Buddha’s ancient warning: relentless mental excitement is a "disease" and a "thorn." It burns us out.

Modern people desperately need the wisdom of the Third Dhyana because it offers a paradigm shift in how we experience happiness. It proves that the highest forms of worldly joy do not require high arousal. You do not need the music to be louder, the vacation to be more expensive, or the success to be more thrilling. By actively *abandoning* the pursuit of the spike (离喜) and cultivating inward-facing equanimity (舍), we unlock a pervasive, sustainable well-being (身受乐) that the external world cannot easily disrupt.

Furthermore, the *Dirgha Agama* (长阿含经) contains a fascinating cosmological metaphor: when the universe is destroyed by a great "Water Disaster" (水灾), those who have attained the "rapture-free Third Dhyana" (无喜第三禅) ascend into the sky and are entirely untouched by the flood. In our contemporary lives, we are constantly drowning in floods—floods of information, economic anxiety, and social pressure. The psychological architecture of the Third Dhyana provides a high-ground refuge where the floodwaters of modern hysteria simply cannot reach.

Common misreadings and clarifications (常见误读与澄清)

Because the Third Dhyana is so peaceful and satisfying, it is incredibly easy to misunderstand its place on the broader path of liberation (解脱道). Here is how a solid friend in the Dharma would help you avoid the common traps:

1. The Illusion of Finality ("This is Enlightenment") The canonical texts note that many ancient spiritual seekers (non-Buddhist ascetics and Brahmins) reached the Third Dhyana and confidently declared, "This is Nirvana here and now" (现在泥洹). This is classified as a severe wrong view. Why? Because as beautiful as the submerged lotus is, the Third Dhyana is still a *constructed* state. The *Madhyama Agama* (中阿含经) reminds us that because there is still "mental pleasure" involved, this state is still subject to "movement" (移动). It is deeply refined, but it is not the Unconditioned (Nirvana). It is a luxurious rest stop, not the final destination.

2. Becoming Addicted to the Peace (心不住内) If a practitioner tastes this exquisite bodily bliss and becomes attached to its "flavor" (无喜味), the sutras warn that their mind is "not dwelling inward" (心不住内). If you die clinging to this state, you will be reborn in the Heavenly Realms—specifically the Heaven of Universal Purity (遍净天, *Subhakinna*). While this sounds wonderful, it means you are still trapped in the cycle of Samsara. When your heavenly lifespan ends, you will fall back down.

3. The Counter-Intuitive Antidote: Contemplating the Aggregates as a Disease How do you enjoy the bliss of the Third Dhyana without getting trapped by it? The *Samyukta Agama* (杂阿含经) offers a brilliant, counter-intuitive technique. While resting in this ultimate peace, the practitioner is instructed to use their Clear Comprehension (正智) to observe their own psychological components. Interestingly, the text specifically mentions observing four aggregates (四阴: 受、想、行、识 — feeling, perception, volitional formations, and consciousness).

You must look at the very fabric of this blissful experience and see it as "a disease, an ulcer, a thorn, a murder" (如病、如痈、如刺、如杀). This doesn't mean you ruin the peace; it means you penetrate the illusion of its permanence. By seeing that even this supreme joy is impermanent and devoid of a fixed self, you cultivate a profound disenchantment (厌离). You use the absolute stability of the Third Dhyana as a microscope to see through the illusion of existence, thus leveraging a state of ultimate worldly happiness to achieve ultimate, world-transcending liberation.

一、 定义与核心要义

第三禅(梵语:tṛtīya-dhyāna)是佛教色界四禅中的第三个禅定阶段。其核心要义在于超越了第二禅的“喜”受,修行者通过“舍喜”而进入一种更为寂静、清净的定境。在此状态下,行者安住于“舍”、“正念”与“正智”(或正知)之中,并在身体上体验到贤圣所称赞的、离喜之“乐”。这一阶段在禅定修行中具有承前启后的关键作用,既是现法安乐的殊胜境界,也是向更高禅定(第四禅)进阶的基石。

二、 主要阐述

各部派经典从修行实践、生动比喻、心境变化、宇宙论等多个维度,对第三禅进行了系统而详尽的阐述:

1. 现身得乐与莲花之喻 第三禅被称为“第三现身得乐”或“世一向乐”。当修行者进入第三禅时,“身无喜,以乐润渍,周遍盈溢,无不充满”。经典以此作了生动的比喻:犹如优钵罗花、钵头摩华、拘头摩花、分陀利华(或青、红、赤、白莲华)等莲花,在未露出水面时,其根、茎、枝、叶完全浸渍在冷水之中,无处不周遍。比丘入第三禅时,其“离喜、住乐”对身体的润渍亦是如此周遍充满。这种乐是远离五欲、恶法及外道苦行后,由精勤不懈、念不错乱所获得的清净之乐。

2. 其他修持比喻 * 昼度树之喻:将圣弟子得第三禅成就游,比作三十三天昼度树“生如鸟喙”的阶段,象征着修行功德的进一步展露。 * 边城积豆之喻:将第三禅比作王边城“多积秥豆及大小豆”以防卫外敌,比喻第三禅能令圣弟子安隐快乐、自致涅槃。 * 山泉湖水之喻:将第三禅的宁静比作“澄清平岸,定不动摇,亦无波浪”的湖水。但经中也警示,若得第三禅后自安住而不求升进,且与白衣共会谈哗,心生欲念,就如同大风吹拂湖水动涌波浪一样,会导致退转。

3. 修持的动态变化与心境控制 * 心之住与不住:若行者对第三禅的“无喜味”产生执着、依缘缚之,则属于“心不住内”;反之,若不着、不依、不缚,则属于“心住内”。 * 炽盛与衰退:行禅者若能正思,从第三禅趣向第四禅,即是“炽盛”;若在第三禅中思余小想,或在第四禅中退行第三禅相标,则属于“衰退”。 * 四种修持导向:处于第三禅的比丘,若行第二禅念想则会“退”;若受持本相则能“住”;若行第四禅念想则能“升进”;若行灭息念想则能“厌”而速得漏尽。 * 观修四阴:若比丘成就第三禅但未能直接证果,则应对“受、想、行、识”这四阴进行思惟,观其“如病、如痈、如刺、如杀”,通过对四阴的厌离与防护,趋向涅槃。

4. 外道误执与宇宙灾变 * 外道误执:部分沙门、婆罗门因未能证得究竟涅槃,而将第三禅的境界误认为现世的最高解脱,主张入第三禅即是“现在泥洹”(此在外道见解中被归纳为“第四见”)。 * 水灾避难:在关于世界坏劫的叙述中,当“水灾”发起、世间遭遇毁灭时,修行十善业并“得无喜第三禅者”,能够凭借禅定力踊身上升到虚空中,从而免受水灾的侵害。

三、 不同部类与译本的表述差异

在不同的经典及译本中,对于第三禅的核心定义和关键术语存在诸多用词上的差异:

1. 核心定义的表述差异 * 《长阿含经》:表述为“捨喜守護,專念不亂(或專心不亂),自知身樂,賢聖所求,護念樂行(或護念、樂行)”;或“除喜入捨,自知身樂,賢聖所求,護念一心”;或“捨喜修護,專念一心,自知身樂,賢聖所求,護念清淨”。 * 《中阿含经》:表述为“离于喜欲,舍无求游,正念正智而身觉乐,谓圣所说、圣所舍、念、乐住、空(或‘乐住室’)”。 * 《杂阿含经》:表述为“离喜”(或“离喜贪”、“离贪喜”),“舍心住正念正智”(或“正知”),“身心受乐”(或“安乐住”、“觉身乐”),“圣说及舍”(或“圣人能说能舍念乐住”)。

2. 独特术语的差异 * 《长阿含经》使用“無喜第三禪”来指代此境界。 * 《中阿含经》则特别以“无喜生乐”来指代第三禅的体验。 * 《杂阿含经》在关于“食”与“舍”的分类中,将第三禅的境界定义为“无食无食乐”与“无食舍”。

3. 观修对象的称呼 * 《杂阿含经》在论述对第三禅境界进行观修时,明确指出是对“受、想、行、识”这“四阴”(而非“四蕴”)进行思惟。

四、 与相关概念的关系

1. 与第二禅、第四禅的关系(次第灭想) 第三禅是超越第二禅之“喜”的定境,在《中阿含经》中明确指出“入第三禅者以喜为刺”。在“次第灭想”的序列中,修行者“舍喜修护,专念一心”时,经历“二禅想灭,三禅想生”;而当修行者进一步“舍苦舍乐,先灭忧喜,护念清净”进入第四禅时,则经历“三禅想灭,四禅想生”。这表明第三禅在禅定序列中具有承前启后的过渡作用。

2. 与“移动”及“增上心”的关系 第三禅被称为“第三增上心”,是行者在现法中易得、无怖的“安乐居”。然而,由于其中仍有“心乐”,因此在圣者看来,第三禅依然属于“移动”而非“不移动”的境界。

3. 与投生天界的关系 修持第三禅且乐欲住者,命终后将往生对应的天界。其所受之乐与比丘在人间入第三禅所受之乐无有差别。 * 《中阿含经》指出其往生“遍净天”。 * 《杂阿含经》则根据修持的精深程度,细分为投生“少净天”(初等)、“无量净天”(中等)或“遍净天”(最上等)。

4. 与慧解脱的关系 虽然具足第三禅是“不起诸漏,心善解脱”的有效途径,但《杂阿含经》明确指出,即使未能证得包括第三禅在内的诸禅定,修行者亦可通过“慧解脱”而自知生死已尽、不受后有。

五、 代表性原文引用

1. 《长阿含经》: “捨喜守護,專念不亂,自知身樂,賢聖所求,護念樂行,得第三禪。”

2. 《中阿含经》: “離於喜欲,捨無求遊,正念正智而身覺樂,謂聖所說、聖所捨、念、樂住、空,得第三禪成就遊。”

3. 《杂阿含经》: “離喜貪,捨心住正念正知,安樂住,彼聖人能說能捨念樂住,第三禪具足住。”

長阿含經T0001 · 阿含部

《長阿含經》多次敘述第三禪的修證,其核心表述為「捨喜守護,專念不亂,自知身樂,賢聖所求,護念樂行,得(或行)第三禪」。此處以「捨喜」對應概念中的「離喜」,以「自知身樂」「護念樂行」對應「具正念樂受」,顯示此經以「捨喜」與「自知身樂」作為界定第三禪的兩組關鍵詞。

此經用詞有一值得留意之處:對應概念中的「正念」,本經悉用「護念」一詞,如「護念不錯亂」「護念一心」「護念樂行」「護念清淨」等,而非「正念」。此外,論及水劫一段復以「無喜第三禪」稱之,「無喜」即指離喜。故本經圍繞「捨喜」「自知身樂」「護念」三個關鍵語來界定第三禪。

第三禪的特質在本經中亦有獨特鋪陳。其一,經中以蓮花為喻,喻第三禪「離喜、住樂,潤漬於身,無不周遍」,如優鉢羅、鉢頭摩、拘頭摩、分陀利等蓮花「始出淤泥而未出水,根莖枝葉潤漬水中,無不周遍」,以喻行者「身無喜,以樂潤漬,周遍盈溢,無不充滿」。此喻別出於初禪以「巧浴器盛眾藥」、第二禪以「山頂涼泉自出池中」之喻,構成四禪漸次的具體意象。

其二,在本經的「現涅槃論」中,第三禪被列為外道沙門婆羅門所執的現涅槃見之一:「如我除念、捨、喜、住樂,護念一心,自知身樂,賢聖所說,入第三禪。齊是名現在泥洹」,標示凡夫可能以此禪為究竟之執,且本經明判其為五見之一,非真涅槃。

其三,在災劫論述中,《長阿含經》以「時,有人得無喜第三禪者,踊身上昇於虛空中,住聖人道、天道、梵道」作為水災後世人重獲善行的徵兆,展現第三禪不僅是個修禪定之境,亦關聯於世間劫數之續轉。

其四,就第三禪與因緣法之關係,經中以「捨喜修護,專念一心,自知身樂,賢聖所求,護念清淨,入三禪」明「彼二禪想滅,三禪想生,以是故知有因緣想滅,有因緣想生」,顯示第三禪同樣為有為有緣之法,依前禪想滅、本禪想生而起。

綜合而言,《長阿含經》以「捨喜—護念—自知身樂」三者並舉作為第三禪之定義語;以「護念」代「正念」為其術語特色;以蓮花出水之喻述其離喜住樂之相;以「無喜」一語概攝其離喜之要;並將此禪列入外道現涅槃之見、置於劫數循環及因緣生滅的框架中。

中阿含經T0026 · 阿含部

本經對第三禪之論述,首見於其固定句式之核心定義:「離於喜欲,捨無求遊,正念正智而身覺樂,謂聖所說、聖所捨、念、樂住室,得第三禪成就遊」。此句以「離於喜欲」與「捨無求遊」標示其離染之相,以「正念正智而身覺樂」標示其受用之相,並以「聖所說、聖所捨、念、樂住室」攝四聖種之「聖所說、聖所捨」及念樂之安住。其中「樂住室」一詞,在早期三段經文中作「樂住、空」,與其餘各處之「樂住室」有別,此異文存於本經自身。

就樂受之特殊表述而言,本經以「無喜生樂」 稱第三禪之身樂,與初禪之「離生喜樂」、第二禪之「定生喜樂」相對,形成「離生、定生、無喜生」三階並列之結構。其喻取「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」,以蓮華之內潤喻此無喜之樂遍漬全身。

本經亦揭示第三禪之獨特側面——「喜」本身即為第三禪之「刺」:「入第三禪者以喜為刺」,意即第三禪雖以離喜為特質,然若執著於「無喜」之味仍為繫縛。故本經於「心住內」之辨中,明示「識著無喜味,依彼住彼,緣彼縛彼,識不住內」,反之則「識不著無喜味……識住內」。

就位次與果德而言,本經列第三禪為「四增上心」之一,具「易不難得,樂住無乏,安隱快樂,令昇涅槃」之德;又以王城喻,喻其如「邊城多積秥豆及大小豆,為內安隱,制外怨敵」之儲備;於異學箭毛經中,世尊明示「比丘……得第三禪成就遊……是謂世一向樂」,以對治外道之執。又以晝度樹為喻,將第三禪喻為「如鳥喙」之生相。

就修行觀察之判釋,本經設「熾盛而謂衰退」、「衰退而謂熾盛」、「衰退則知衰退如真」、「熾盛則知熾盛如真」四種行禪者之辨,又以「退、住、昇進、厭」四相觀察第三禪之修行位次。並以「不如實知」為警:得第三禪者若不更進,「猶山泉湖水,澄清平岸,定不動搖……四方大風卒來,吹彼湖水,動涌波浪」,仍可退墮。

就受生而言,本經明第三禪與色界「遍淨天」相應,彼天所受「無喜樂」與人間入第三禪者所受「無喜樂」無有差別。又以「聖說移動」攝第三禪中「說移動心樂」之受;以晡利多居士聞法「遠塵離垢,諸法法眼生」證初果,顯第三禪趣向解脫之階梯意義。

雜阿含經T0099 · 阿含部

本經論述第三禪,主要見於三處,以下分三點說明。

一、核心表述:第三禪以「離喜」為其入定之相,於捨中安住正念正智(或正念正知),身心(或身)領受安樂。本經對第三禪的標準描述見於須深經:「離喜,捨心住正念正智,身心受樂,聖說及捨,具足第三禪」。此中包含三項要素:(一)離喜——捨離第二禪之喜;(二)捨心住正念正智——以捨心安住,具正念與正智;(三)身心受樂——身心領受安樂之受,並由聖者所說之「捨」而住。同樣內容於食念經以「無食捨」為名重述:「離喜貪,捨心住正念正知,安樂住彼聖說捨,第三禪具足住」;廣演經則作:「離貪喜,捨住正念正智,覺身樂,聖人能說能捨念樂住,第三禪具足住」。三處描述結構一致,皆以「離喜、捨住、正念正智、樂受、聖說捨」五項為第三禪之自相。

二、獨特側面: (一)「食」門分類:本經從「食念、食樂、食捨、食解脫」四組九項的框架安立第三禪。第三禪同時被標為「無食無食樂」與「無食捨」——前者就所緣之樂而立,後者就其捨之自性而立。「無食無食樂」定義為「離喜貪,捨心住正念正知,安樂住彼聖說捨」;「無食捨」定義為「彼比丘離喜貪,捨心住正念正知,安樂住彼聖說捨,第三禪具足住」。兩者定義幾近相同,唯後者明言「第三禪具足住」,前者未明說之。 (二)「貪」字加於「喜」前:本經常見作「離喜貪」或「離貪喜」,突顯所離者為喜之貪著,語意較一般「離喜」更為細膩。 (三)條件鏈與果報:本經以「若……若不爾者……」之連鎖語句,將第三禪具足住與「受、想、行、識法思惟如病、如癰、如刺、如殺」、「欲法、念法、樂生遍淨天」、「生無量淨天」、「生少淨天」相連結,顯示第三禪具足住者能以「覺身樂、念樂住」直住;若不爾,則退墮至較下之果報。此條記錄了第三禪與遍淨天、無量淨天、少淨天等色界天之對應關係。

三、術語形式:本經對第三禪所用核心詞為「離喜(或離喜貪、離貪喜)」、「捨心住(或捨住)」、「正念正智(或正念正知)」、「聖說捨(或聖人能說能捨、聖說及捨)」。其中「正智」與「正知」於同一概念上交替使用:chunk:5999、chunk:7965作「正智」;chunk:6339作「正知」。「聖說捨」、「聖人能說能捨」與「聖說及捨」為同義異寫,須深經所用之「及」字,可作為本經內部異譯詞形之記錄。
