全文五層 →Full five layers →一、十七地的最後一地——「無餘」二字落在哪裡
走過十六地,到了本地分的盡頭。最後這一地,名字裡只多了一個「無」字——有餘依、無餘依。這一字之差,差在哪裡?
有餘依地(地16)是阿羅漢『惑業苦已寂,而最後一具身的蘊猶在』的涅槃位;到了無餘依地,連這最後一具身的蘊也滅了。成唯識論說得最直截:無餘依涅槃「謂即真如出生死苦,煩惱既盡,餘依亦滅,眾苦永寂」。「有餘」之所「餘」,正是那後邊身;「無餘」者,餘依亦滅。所以攝決擇分以一組對句畫出二界之別:「住有餘依,墮在眾數;住無餘依,不墮眾數。住有餘依,猶有眾苦;住無餘依,永離眾苦」——身在則墮於有情之數、猶有眾苦;身滅則出數離苦。
論文以三相攝這一地:地施設、寂滅施設、寂滅異門。下面順著走。
二、它的「地盤」是怎麼劃出來的——地施設安立
奇怪的是,這一地不先說它「是什麼」,先說它『佔哪塊地』。為什麼用這種劃法?
因為無餘依不是十七地之外另起的一地,而是從前面諸地裡「除出來」的那一分。論文說:無餘依地=先前所除的「五地一分」——無心地、修所成地、聲聞、獨覺、菩薩地。窺基把這把剪刀說得很細:無心地有五位無心,唯獨「入無餘依涅槃」那一位歸無餘依;修所成地中「其無為是無餘依體,今除之」;聲聞等地的滅諦「簡去果盡無為」。換言之,凡是這五地中指向「究竟寂滅之無為」的那一分,都歸到這最後一地來。所以窺基說無餘依地「此地體即前地所餘者是,義准前知」——它的體,就是前面諸地除剩、指向究竟寂滅的那一分。
這是一種很深的安立法:究竟涅槃不在別處,就在修行諸地各自指向的那個「無為」的盡頭,把它們收攏為一地。
三、「滅」有兩種——寂靜寂滅與無損惱寂滅
說到「寂滅」,最易誤會成什麼都沒有了的頑空。論文偏在這裡分了兩種滅,把誤會擋住。
寂靜寂滅——是「息」的一面。有餘依地中已觸證的四種寂靜,到無餘依界更得其最勝:數教寂靜(言教之數皆息)、一切依寂靜(離前八依)、依依苦寂靜(依八依所生之苦永滅)、依依苦生疑慮寂靜(連那「未來苦生不生」的疑慮也無)(遁倫引景師釋)。這一面,論文配了一個喻——
「由無下劣心,能忍受勤苦,彼所趣解脫,譬如燈盡滅。」(末句底本作「燈盡滅」,宋元明宮本作「證涅槃」、聖知本作「燈涅槃」;遁倫判釋正就「燈盡滅」立喻,故從底本。)遁倫判這頌的第四句「是無餘果」。燈油盡則火自滅,不是另有一隻手去吹熄它;無餘依的寂滅也如此——惑業苦因既盡、堪忍勤苦既辦,後苦不續,如燈盡而滅,更無餘依可然。寂滅不是被製造出來的斷滅,是因盡而火自息。
無損惱寂滅——是「顯」的一面,也是這一地的唯識結穴。論文說它「與一切依不相應,違背一切煩惱諸苦流轉,生起轉依所顯真無漏界」、「由此清淨真如所顯,一向無垢」。注意:無餘依的滅,不是空無一物,而是「轉依所顯」的真無漏界——轉捨煩惱所依、轉得真如所顯。遁倫直接點到唯識的轉依義:「依攝論明六種轉依,今時所辨即是圓滿轉」。所以「無餘」的另一面,恰恰是「真如所顯」的圓滿——空掉的是惑業苦的依,顯出的是一向無垢的清淨真如。這一句,把二乘的無餘依涅槃,接到了唯識轉依的同一條真如上。
論文還引了一段佛語護住這個分寸:實有「無生、無起、無作、無為」的涅槃,正因為實有它,才說有為流轉法有「永出離」可言。涅槃不是流轉法的虛擬反面,而是實有的、作為出離之所依的無為界。
四、為什麼要堆這麼多名字——寂滅異門與「不可說」
最後一相,論文一口氣堆了二十幾個名字:常、恒、久住、舍宅、洲渚、歸依、甘露、無病、涅槃、永絕一切戲論……為什麼一個寂滅要安這麼多異名?
因為它「數不能數」。論文自釋:甚深(功德難了知)、廣大(極寬博)、無量(無窮盡)、無數(數不能數、無二可說)。而「數不能數」的所以然,是一串「不可說」:是有、非有不可說,即色、離色不可說,乃至即識、離識不可說——這真如所顯,落不進「有/無」「即蘊/離蘊」任何一句。
正因為一句說不盡,才以無量異門從各個側面去指:從常住說「常、恒、久住、無變」,從歸投說「舍宅、洲渚、救護、歸依、所趣」,從安樂說「安隱、甘露、無憂、無病」,從離染說「無垢、無熱、無熾」,終以「涅槃、永絕一切戲論」收束。堆名字不是繁瑣,是因為它本身離言——只能多方旁指,不能一語道盡。
五、承衍——這一地,後論如何接續
無餘依地是十七地之終、三乘果之究竟;後出諸論各就一面而廣決、而深判。承衍之脈如下。
-
有餘依地(地16)成二涅槃界對:有餘(身存·墮數·有苦)/無餘(身滅·不墮數·離苦)。攝決擇分「正決擇有餘及無餘依二地」合二地於一決,以離繫、轉依、住、差別等十四門廣辨之;尤其決出無餘依之轉依「唯用緣真如境修道為因…非所遍知、非所應斷,故不可滅」——無餘依界的真如轉依,是常住不可滅的,非斷滅。
-
成唯識論四涅槃:本來自性清淨/有餘依/無餘依/無住處。「一切有情皆有初一,二乘無學容有前三,唯我世尊可言具四」。二乘無學止於無餘依之「住寂」,菩薩則更有無住處涅槃之「寂而不住」——本地無餘依,正是二乘無學所趣之究竟,亦是唯識四涅槃中的第三位。
-
獨覺地(地14)·有餘依地(地16)·無餘依地(地17)一線:獨覺「一向趣寂」→ 有餘依「住寂(身存)」→ 無餘依「寂滅(身滅)」——三乘果之次第,至此盡。
-
修所成地(地12):最勝子判「修所成地,亦是有餘無餘依地」——修慧所成之無為功德,上攝於無餘依。修慧之果,於此通入究竟涅槃地。一地之終,原是全部修證的歸宿。
One · The Last of the Seventeen Stages — Where Do the Words "Without Remaining" Fall?
Having walked through sixteen stages, we come to the very end of the Basic Section. This last stage differs from the one before it by a single character: with remaining basis, without remaining basis — 有餘依, 無餘依. This single-character difference — where does it lie?
The Stage with Remaining Basis (Stage 16) is the nirvāṇa-station of the arhat in whom "the affliction, the karma, and the suffering are already stilled, yet the aggregates of one last body still remain"; by the Stage without Remaining Basis, even the aggregates of this one last body have ceased. The Cheng Weishi Lun puts it most directly: nirvāṇa without remaining basis "means just suchness that has passed out beyond the suffering of birth-and-death; the afflictions being already exhausted, the remaining basis too is extinguished, and all sufferings are forever quiescent". What "remains" in "with remaining" is precisely that latter-end body; in "without remaining," the remaining basis too is extinguished. So the Section on Ascertainment marks off the difference between the two realms with a set of matched couplets: "One who dwells with remaining basis falls within the count of [sentient] beings; one who dwells without remaining basis does not fall within the count. One who dwells with remaining basis still has the mass of sufferings; one who dwells without remaining basis is forever apart from the mass of sufferings" — while the body remains, one falls within the count of sentient beings and still has the mass of sufferings; when the body is extinguished, one departs from the count and is apart from suffering.
The treatise subsumes this stage under three aspects: the establishing-designation of the stage, the establishing-designation of quiescence, and the synonyms of quiescence. Let us follow them in order.
Two · How Is Its "Territory" Marked Out? — The Establishing-Designation of the Stage
It is a curious thing: this stage does not first say what it "is"; it first says which "territory" it occupies. Why mark it out in this way?
Because the Stage without Remaining Basis is not some further stage set up outside the seventeen, but that one portion "cut out" from the earlier stages. The treatise says: the Stage without Remaining Basis = the "one portion of five stages" removed earlier — the Stage without Mind, the Stage of What is Attained through Cultivation, the Śrāvaka, the Pratyekabuddha, and the Bodhisattva Stage. Kuiji describes this pair of shears very finely: within the Stage without Mind there are five phases of mindlessness, and of these it is uniquely the phase of "entering nirvāṇa without remaining basis" that belongs to the Stage without Remaining Basis; within the Stage of What is Attained through Cultivation, "its unconditioned [portion] is the substance of the Stage without Remaining Basis, and is here removed"; and from the Śrāvaka and the other stages, "the unconditioned [reached by] the exhaustion of the fruit is selected out". In other words, whatever within these five stages points to "the unconditioned that is ultimate quiescence" all belongs to this last stage. And so Kuiji says of the Stage without Remaining Basis: "the substance of this stage is just what remains over from the earlier stages; its sense is to be inferred from what precedes" — its substance is that portion left over from the earlier stages, the portion pointing to ultimate quiescence.
This is a very deep way of establishing a thing: ultimate nirvāṇa is nowhere else; it is right at the far end of that "unconditioned" toward which each of the stages of practice points, gathered together into a single stage.
Three · There Are Two Kinds of "Extinction" — The Quiescence of Stillness and the Quiescence of Freedom from Harm-and-Distress
When one speaks of "quiescence," it is most easily mistaken for a stubborn emptiness in which nothing at all is left. Precisely here the treatise divides extinction into two kinds, to hold off that mistake.
The quiescence of stillness — this is the aspect of "ceasing." The four kinds of stillness already directly realized in the Stage with Remaining Basis attain their most excellent form in the realm without remaining basis: the stillness of teaching-and-number (the numbers of verbal teaching all cease), the stillness of all bases (departure from the former eight bases), the stillness of the suffering [that arises] from the bases (the suffering born of the eight bases is forever extinguished), and the stillness of the anxious doubt [arising] from the suffering [that arises] from the bases (even that anxious doubt over "whether future suffering will or will not arise" is gone) 〔Dunlun cites Master Jing's explanation〕. To this aspect the treatise fits a simile —
"Because he is without a lowly and inferior mind, he can endure toil and hardship; the liberation toward which he tends is like the extinction of a lamp when [its fuel] is spent." 〔The base text has the final line as 「燈盡滅」 "the extinction of a lamp when [its fuel] is spent"; the Song, Yuan, Ming, and Palace editions have 「證涅槃」 "realizes nirvāṇa," the Sheng and Zhi editions 「燈涅槃」 "the lamp['s] nirvāṇa"; since Dunlun's adjudicating explanation sets up its simile precisely on "the extinction of a lamp," the base text is followed.〕 Dunlun judges the fourth line of this verse to be "the fruit without remaining". When the lamp's oil is spent the flame goes out of itself — it is not that some other hand comes to blow it out; and so it is with the quiescence without remaining basis: the causes, the affliction, the karma, and the suffering, being already exhausted, and the endurance of toil already accomplished, the later suffering does not continue, and it goes out like a lamp whose fuel is spent, with no remaining basis left to burn. Quiescence is not an annihilation that is manufactured; it is the flame going still of itself because its cause is spent.
The quiescence of freedom from harm-and-distress — this is the aspect of "manifesting," and it is also the Consciousness-Only knot of this whole stage. The treatise says it "is not associated with any basis whatsoever, runs counter to the flow-and-turning of all afflictions and sufferings — the true uncontaminated realm made manifest by the arising of the transformation of the basis," and that "it is made manifest by this pure suchness, and is throughout without stain." Mark this well: the extinction without remaining basis is not a nothing-at-all; it is the true uncontaminated realm "made manifest by the transformation of the basis" — the turning-away-from the basis of the afflictions, and the turning-toward the manifesting of suchness. Dunlun points directly to the Consciousness-Only sense of the transformation of the basis: "Following the Mahāyānasaṃgraha's account of the six kinds of transformation of the basis, what is here distinguished is just the perfect and complete transformation". So the other aspect of "without remaining" is precisely the fullness of "suchness made manifest" — what is emptied out is the basis of affliction, karma, and suffering; what is made manifest is the pure suchness throughout without stain. This one line joins the nirvāṇa without remaining basis of the two vehicles onto the very same suchness of the Consciousness-Only transformation of the basis.
The treatise further cites a passage of the Buddha's word to guard this measure: there truly is the "unborn, unarisen, unmade, unconditioned" nirvāṇa, and precisely because there truly is it, one can then speak of the conditioned, flowing-and-turning dharmas as having a "forever going-forth-and-out." Nirvāṇa is not the fictitious opposite of the flowing dharmas; it is the truly existent unconditioned realm that serves as the basis for going forth and out.
Four · Why Pile Up So Many Names? — The Synonyms of Quiescence and the "Inexpressible"
In the last aspect the treatise piles up, all in one breath, some two dozen names: the constant, the enduring, the long-abiding, the dwelling-house, the island, the refuge, the ambrosia, the disease-free, nirvāṇa, the forever cutting-off of all idle proliferation … Why should a single quiescence be set with so many synonyms?
Because it "cannot be numbered." The treatise glosses itself: profound (its merits hard to comprehend), vast (utterly broad and ample), measureless (without exhaustion), numberless (number cannot number it, there being nothing dual to be spoken of). And the reason that "number cannot number it" is a string of "cannot be spoken of": whether it "is" or "is not" cannot be spoken of, whether identical with form or apart from form cannot be spoken of, on down to whether identical with consciousness or apart from consciousness cannot be spoken of — this suchness-made-manifest falls into none of the sentences "is / is-not," "identical-with-the-aggregates / apart-from-the-aggregates."
Precisely because no single sentence can exhaust it, it is pointed at from every side through measureless synonyms: from the side of constant abiding come "the constant, the enduring, the long-abiding, the unchanging"; from the side of taking refuge come "the dwelling-house, the island, the rescue-and-shelter, the refuge, that toward which [beings] tend"; from the side of ease and bliss come "the secure, the ambrosia, the sorrowless, the disease-free"; from the side of departing defilement come "the stainless, the unburning, the unblazing"; and it closes with "nirvāṇa, the forever cutting-off of all idle proliferation." The piling-up of names is not fussiness; it is because the thing itself is apart from speech — it can only be indicated pointing-around from many sides, and can never be exhausted in a single utterance.
Five · Carrying Forward — How the Later Treatises Continue This Stage
The Stage without Remaining Basis is the end of the seventeen stages and the ultimate of the fruit of the three vehicles; the treatises that come after each take up one facet of it and ascertain it broadly, adjudicate it deeply. The veins of the carrying-forward run as follows.
-
With the Stage with Remaining Basis (Stage 16) it forms the pair of the two nirvāṇa-realms: with remaining (the body remains · falls within the count · has suffering) / without remaining (the body is extinguished · does not fall within the count · is apart from suffering). The Section on Ascertainment's "proper ascertaining of the two stages, with and without remaining basis" joins the two stages in one ascertainment, distinguishing them broadly through fourteen gates — release-from-bondage, transformation of the basis, dwelling, difference, and the rest; and it ascertains in particular that the transformation of the basis without remaining basis "takes as its cause only the cultivating of the path whose object is suchness … it is not to be fully known, not to be cut off, and so cannot be extinguished" — the suchness-transformation-of-the-basis of the realm without remaining basis is constantly abiding and inextinguishable, not an annihilation.
-
The four nirvāṇas of the Cheng Weishi Lun: intrinsically pure by original nature / with remaining basis / without remaining basis / non-abiding. "All sentient beings possess the first; those of the two vehicles who are beyond training may possess the first three; only our World-Honored One may be said to possess all four". Those of the two vehicles beyond training halt at the "dwelling in quiescence" of the [nirvāṇa] without remaining basis; the bodhisattva has further the "quiescent yet non-abiding" of the non-abiding nirvāṇa. The [stage] without remaining basis of the Basic Section is precisely the ultimate toward which those of the two vehicles beyond training tend, and it is likewise the third of the four nirvāṇas of Consciousness-Only.
-
The Pratyekabuddha Stage (14) · the Stage with Remaining Basis (16) · the Stage without Remaining Basis (17) in one line: the pratyekabuddha "tends one-pointedly toward quiescence" → the [stage] with remaining basis is "dwelling in quiescence (the body remains)" → the [stage] without remaining basis is "quiescence-and-extinction (the body extinguished)" — the sequence of the fruit of the three vehicles reaches its end here.
-
The Stage of What is Attained through Cultivation (12): Jinaputra judges that "the Stage of What is Attained through Cultivation is also a stage with and without remaining basis" — the unconditioned merit accomplished by the wisdom of cultivation is subsumed upward into the [stage] without remaining basis. The fruit of the wisdom of cultivation here passes into the stage of ultimate nirvāṇa. The end of a single stage is, from the first, the resting-place of the whole of practice-and-realization.
