獨覺地The Basic Section · The Pratyekabuddha Stage
全文五層 →Full five layers →聲聞之後、菩薩之前,為何單立這一乘
十七地裡,聲聞(十三)、獨覺(十四)、菩薩(十五)三地相連,正是三乘並列。聲聞與菩薩我們都熟:一個聞佛聲教而修四諦,一個發大悲心行六度。可夾在中間這「獨覺」,到底是什麼?它既不在佛世聞法,又不發心度生,像是兩頭不靠——論何以還要單立一地,鄭重其事地說它的種姓、道、習、住、行?
最勝子釋一句點出它的位分:「常樂寂靜,不欲雜居,修加行滿,無師友教自然獨悟,永出世間。中行中果,故名獨覺。或觀待緣而悟聖果,亦名緣覺。」(最勝子釋)——它是「中行中果」之乘:行不及菩薩之大,而過於聲聞之依師;果不及佛之圓,而出於三界之外。它最堪玩味的,不是它證到了什麼,而是它『怎麼證、又為什麼證了卻不說』。這一地,是三乘並列時,那面照出「覺而薄悲」是什麼模樣的鏡子。
種姓裡,已經藏好了結局
論說獨覺種姓有三相,初讀像是三項資格,細看卻是三道伏筆——獨覺一生的孤獨與沉默,早在種姓裡就寫定了。
其一薄塵:煩惱塵染本薄,故「於憒鬧處心不愛樂,於寂靜處深心愛樂」——他天生就往靜裡去。其二薄悲:悲心本薄,故「於說正法利有情事心不愛樂,於少思務寂靜住中深心愛樂」——他天生就不愛管眾生的事。其三中根慢行:根器中等而帶慢習,故「深心希願無師、無敵而證菩提」——他天生就想靠自己、不要老師、不要對手地證道。
把這三相連起來讀,獨覺的「果」已在「因」中現形:愛靜(薄塵)、不樂利生(薄悲)、要獨自成就(慢行)——這樣的種姓,結出來的,必然是一個「出無佛世、無師自悟、樂寂不說法」的覺者。種姓即命脈:你是什麼種姓,便走什麼道、成什麼果。這正是唯識「各從自種」之理,在一整條成佛之路上的放大——獨覺之為獨覺,不是半路選擇的,是種姓裡帶來的。
麟角與部行:兩種「獨」
那獨覺是怎麼修成的?論列三道、三習,而以兩個譬喻收束,分出兩種「獨」。
依「初獨覺道」者:安住種姓、經百劫、值佛時親近承事、修蘊處界緣起處非處諦「六善巧」,卻把證悟留待無佛之世——這一類,「由初習故成獨覺者,名麟角喻」:如犀牛頭上那隻獨角,自始至終只他一個,純然的孤覺。依「第二、第三道」者:本是聲聞道上已起煗頂忍、或已得沙門果的人,只是當生無力究竟,遂留待後世無佛時獨自完成——這一類「名部行喻」:曾在僧團(部眾)中行過、最後獨成。
兩種獨,分量不同:麟角是「生而獨」,部行是「行而獨」。遁倫於此判得分明:「初名麟角,後二名部行」,並引《對法論》第十三相參(遁倫)。但無論哪一種,共同點是那四個字——出無佛世,無師自能修三十七菩提分而證。沒有佛、沒有師、沒有教,他獨自把緣起觀到底、把道修到底。這是獨覺最硬的骨:覺,可以一個人走到底。
住與行:覺到了,卻說不出口
可也正是在「住」與「行」裡,獨覺走到了它走不過去的那一步。
麟角喻獨覺的「住」,是「樂處孤林、樂獨居住、樂甚深勝解、樂觀察甚深緣起道理、樂安住最極空、無願、無相作意」——他住在最深的空寂裡,把十二緣起順逆觀到澈底。這是極高的境地:無師而能洞見緣起、安住三解脫門。
但到了「行」,那薄悲的種姓便顯出它的限度。論說獨覺隨村邑而住、善護身根正念,遇著下劣愚昧者也會「濟度」——可怎麼濟度?「以身濟度,不以語言」:他只現身相、示神通,乃至讓起誹謗的人轉生歸向,卻「唯現身相為彼說法,不發言故」。他度人,是默默地現一個身、顯一點神通,而始終不開口說法。為什麼不說?種姓裡早寫了:薄悲。悲心既薄,便發不出「為眾生宣法」的不倦之願。於是論末一句把獨覺的全幅定了調:「又彼一切,應知本來一向趣寂。」——他打從根本,就一徑朝寂滅去。
這是獨覺最動人、也最堪深思的一筆:他有真覺、能獨悟、住最深空寂,卻因悲薄而「覺得到、說不出口」;他能以身度人,卻不能以法度人。覺與悲,在他這裡是分開的——有覺而悲不滿。
此地照出的一義
獨覺地看似只是給「中乘」記一筆履歷,實則是三乘並列時最要緊的一面鏡:它照出「覺而薄悲」會是什麼結局——一向趣寂、以身代口、不興法化。把獨覺放在聲聞與菩薩之間,正為反顯:聲聞依師而覺、獨覺無師而寂、菩薩則覺悲雙運、大行大果而「不住涅槃」。獨覺走到了『一個人覺到底』的極處,卻也恰在這極處停住——停在「趣寂」,過不去「悲願度生」那一關。
所以這一地不是要我們慕獨覺之孤高,也不是要貶它之薄悲,而是要我們看清:覺,若無大悲攝持,便只能成就一個趣寂的獨者;要不住生死、不住涅槃,須得覺悲同時。 獨覺以它的沉默,替菩薩道說出了「大悲」二字何以不可少。一個說不出口的覺者,正是大悲法門最有力的反證。
承衍
本地獨覺義,後論承衍而互參:《對法論》(集論·雜集論)第十三辨獨覺(遁倫引);攝決擇分不別立獨覺地決擇(科目標「獨覺地缺」);麟角喻·部行喻之分,後世判教三乘時恆引為「中乘二類」之據。三乘並觀,獨覺正居其中——上承聲聞之依四諦、下形菩薩之大悲,三地一線,缺此中乘則三乘不全。
After the Śrāvaka, Before the Bodhisattva — Why Set Up This One Vehicle by Itself
Among the seventeen stages, the śrāvaka (thirteenth), pratyekabuddha (fourteenth), and bodhisattva (fifteenth) stages stand joined in a row — exactly the three vehicles set side by side. Both the śrāvaka and the bodhisattva are familiar to us: the one hears the Buddha's vocal teaching and cultivates the four truths; the other arouses the mind of great compassion and practices the six perfections. But this "pratyekabuddha," wedged in between, what exactly is it? He neither hears the Dharma in a buddha's age nor arouses the resolve to deliver beings — he seems to lean on neither side. Why, then, does the treatise still set up a stage for him by himself, and gravely at that, expounding his lineage, path, practice, dwelling, and conduct?
Jinaputra's commentary points out his rank in a single stroke: "He constantly delights in quiescence and does not wish to dwell mingled [with others]; his intensified practice being complete, without the teaching of teacher or friend he awakens of himself, alone and spontaneously, and forever departs the world. Middling in practice and middling in fruit, he is therefore named a pratyekabuddha [a solitary awakener]. Or, because he awakens to the noble fruit by contemplating conditions, he is also named a pratyekabuddha [a condition-awakener]" 〔Jinaputra's Commentary〕. His is a vehicle "middling in practice and middling in fruit": his practice does not reach the greatness of the bodhisattva, yet it surpasses the śrāvaka's reliance on a teacher; his fruit does not reach the fullness of a buddha, yet it goes beyond the three realms. What most repays reflection in him is not what he realizes, but how he realizes it — and why, having realized it, he does not speak. This stage is, when the three vehicles are set side by side, the very mirror that shows what "awakening yet thin in compassion" looks like.
Within the Lineage, the Ending Is Already Stored Up
The treatise says the pratyekabuddha lineage has three marks. On a first reading they look like three qualifications; looked at closely, they are three buried threads — the loneliness and silence of the pratyekabuddha's whole life are already written into the lineage.
First, thin defilement: the dust of affliction is by nature thin in him, and so "in clamorous places his mind takes no delight, while in quiet places his heart delights deeply" — he inclines, from birth, toward the still. Second, thin compassion: his compassion is by nature thin, and so "in the matter of expounding the true Dharma and benefiting sentient beings his mind takes no delight, while in dwelling quietly with few affairs and cares his heart delights deeply" — he is, from birth, disinclined to trouble himself with the affairs of beings. Third, middling faculties, acting with pride: his capacity is of the middling grade and carries the habit of pride, and so "his heart deeply longs to realize awakening without a teacher and without a rival" — he wants, from birth, to realize the path relying on himself, wanting neither teacher nor rival.
Read these three marks together, and the pratyekabuddha's "fruit" already takes form within his "cause": loving stillness (thin defilement), not delighting to benefit beings (thin compassion), and willing to accomplish the goal alone (proud practice) — a lineage such as this must bear, as its fruit, an awakened one who is "born in an age without a buddha, awakens of himself without a teacher, delights in quiescence and does not expound the Dharma." Lineage is destiny's very artery: what lineage you are, that is the path you walk and the fruit you accomplish. This is precisely the Consciousness-Only principle that "each [factor] arises from its own seed," enlarged across a whole road to buddhahood — the pratyekabuddha's being a pratyekabuddha is not a choice made midway, but something carried within the lineage from the start.
The Rhinoceros Horn and the Group-Dwellers: Two Kinds of "Solitary"
So how is a pratyekabuddha cultivated to completion? The treatise lists three paths and three practices, and draws them to a close with two similes, dividing out two kinds of "solitary."
For the one who follows the "first pratyekabuddha path": he settles in the lineage, passes a hundred aeons, draws near and serves [a buddha] in a buddha's age, and cultivates the "six skills" — in the aggregates, the sense-bases, the elements, dependent origination, the possible-and-impossible, and the truths — yet reserves his realization for an age without a buddha. This class, "the one who becomes a pratyekabuddha through the first practice, is called [an instance of] the rhinoceros-horn simile": like that single horn upon the rhinoceros's head, from first to last he alone, a wholly solitary awakening. For the one who follows the "second and third paths": he is originally one who, on the śrāvaka path, has already aroused warmth, summit, and acceptance, or has already attained a fruit of the renunciant's life, only that in the present life he lacks the power to reach the consummation, and so reserves it for a later, buddha-less age to complete alone. This class "is called [an instance of] the group-dwelling simile": one who once practiced within the community (the assembly) and in the end became solitary.
The two solitudes differ in weight: the rhinoceros-horn is "solitary by birth"; the group-dwelling is "solitary by practice." Dunlun draws the distinction here sharply: "The first is named the rhinoceros-horn; the latter two are named the group-dwelling," and he cites the Abhidharma-samuccaya, fascicle thirteen, for comparison 〔Dunlun, Notes〕. But whichever of the two, the common point is those very words — born in an age without a buddha, teacherless able of himself to cultivate the thirty-seven factors of awakening and so to realize [the goal]. With no buddha, no teacher, no teaching, he contemplates dependent origination through to the end of himself and cultivates the path through to the end. This is the pratyekabuddha's hardest bone: awakening can be walked, by one person, all the way to the end.
The Dwelling and the Conduct: Awakened, Yet Unable to Say It Aloud
Yet it is precisely in the "dwelling" and the "conduct" that the pratyekabuddha comes to the one step he cannot walk past.
The "dwelling" of the rhinoceros-horn-simile pratyekabuddha is to "delight to abide in a solitary grove, delight to dwell alone, delight in profound resolute conviction, delight to contemplate the principle of the profound dependent origination, delight to rest in the attention to the utmost emptiness, wishlessness, and signlessness" — he dwells in the deepest emptiness and quiescence, contemplating the twelvefold dependent origination, forward and reverse, through to the very bottom. This is an exceedingly high station: teacherless, yet able to see through dependent origination and to rest in the three gates of liberation.
But when it comes to "conduct," the lineage of thin compassion shows its limit. The treatise says the pratyekabuddha dwells in dependence on villages and towns, well guarding his body, faculties, and right mindfulness, and that even when he meets one who is lowly and benighted, he "rescues and delivers" him — but how does he rescue and deliver? "He rescues and delivers by the body, not by speech": he only manifests bodily form and displays supernormal power, so as even to turn one who has aroused slander toward giving himself over [to the Dharma] — yet "because he expounds the Dharma to them by manifesting bodily form alone, and does not utter words." When he delivers others, it is by silently manifesting a body and showing a little supernormal power, and from beginning to end he does not open his mouth to expound the Dharma. Why does he not speak? The lineage already wrote it down: thin compassion. His compassion being thin, he cannot bring forth the tireless vow to "proclaim the Dharma for the sake of beings." And so the treatise's closing line sets the whole keynote of the pratyekabuddha: "And all these [pratyekabuddhas], it should be known, are from the outset wholly bent toward quiescence." — From the very root, he heads by a single road toward quiescence.
This is the pratyekabuddha's most moving, and most reflection-worthy, stroke: he has true awakening, can awaken alone, and dwells in the deepest emptiness and quiescence, yet because his compassion is thin, he "attains the awakening but cannot say it aloud"; he can deliver others by the body, but cannot deliver them by the Dharma. Awakening and compassion, in him, are set apart — there is awakening, but the compassion is not full.
The One Meaning This Stage Holds Up to the Light
The Pratyekabuddha Stage looks like nothing more than a résumé entered for the "middle vehicle," but it is in fact the most crucial of mirrors when the three vehicles are set side by side: it holds up to the light what "awakening yet thin in compassion" ends in — wholly bent toward quiescence, using the body in place of the mouth, raising no transformation-through-Dharma. To place the pratyekabuddha between the śrāvaka and the bodhisattva is precisely to throw into relief, by contrast: the śrāvaka awakens in reliance on a teacher; the pratyekabuddha, teacherless, [inclines to] quiescence; and the bodhisattva runs awakening and compassion together, in great practice and great fruit, and "does not abide [in nirvāṇa]." The pratyekabuddha reaches the utmost of "awakening, by one person, to the end," and yet at that very utmost he halts — halts at "bent toward quiescence," unable to cross the pass of "the compassionate vow to deliver beings."
So this stage is not asking us to admire the pratyekabuddha's lonely loftiness, nor to disparage the thinness of his compassion, but to make us see clearly: awakening, if it is not held and gathered by great compassion, can only accomplish a solitary one bent toward quiescence; to abide neither in birth-and-death nor in nirvāṇa, one must have awakening and compassion at once. By his silence, the pratyekabuddha says on the bodhisattva path's behalf why the two words "great compassion" cannot be dispensed with. An awakened one who cannot say it aloud is the most forceful proof, by contrary, of the great-compassion gate of the Dharma.
Carrying Forward
The pratyekabuddha meaning here in the Basic Section is carried forward by the later treatises for mutual reference: the Abhidharma-samuccaya (the Compendium and the Miscellaneous Compendium), fascicle thirteen, discusses the pratyekabuddha (cited by Dunlun); the Section on Ascertainment sets up no separate ascertainment of the Pratyekabuddha Stage (the outline notes "the Pratyekabuddha Stage is absent"); and the division into the rhinoceros-horn simile and the group-dwelling simile is constantly drawn upon, in the later classification of the teachings, as the authority for "the two classes of the middle vehicle." Contemplating the three vehicles together, the pratyekabuddha stands squarely in the midst — inheriting above the śrāvaka's reliance on the four truths, and setting off below the bodhisattva's great compassion; the three stages are a single line, and without this middle vehicle the three vehicles are not complete.
