經
無為作為阿毘達磨之獨立本體範疇（asaṃskṛta-dharma），於阿含／尼柯耶不作明確列位；其經藏概念線索可由「煩惱永盡」詞群追溯，然論藏之「擇滅」分位係 Sarvāstivāda 阿毘達磨時期始見三無為之一（虛空／擇滅／非擇滅），瑜伽行派進一步擴為六（《大乘百法明門論》）／八（《阿毘達磨集論》），並於《成唯識論》卷二系統重判為假立（prajñapti）。六無為之 8-vs-6 架構與假立框架詳 (→#95 詞族框架已詳)。
[共傳] 《雜阿含經》890（T02n0099, T02.0224a29–b05）以煩惱永盡定義無為法：
云何無為法？謂貪欲永盡，瞋恚、愚癡永盡，一切煩惱永盡，是無為法。云何為無為道跡？謂八聖道分。
——無為法之實質內容為「煩惱永盡」，通往無為法之道為八正道。此為擇滅無為之阿含層次根據——「煩惱永盡」正是 pratisaṃkhyā-nirodha 之過程描述，但阿含此處以整體性語言概述，尚未析為每一煩惱類別各成一滅之論藏分位。
[大乘] ⚠️ 本條無獨立大乘經典錨點確認（驗證報告未見此條之專屬大乘引文）；六無為之大乘根據見《成唯識論》卷二之「五依真如假立」論述，不另立單獨大乘經錨。
論
擇滅之論藏定義由淺入深四層：
《大乘五蘊論》（T31n1612, T31.0850a21–22，世親早期前唯識立場）：
云何擇滅？謂若滅是離繫。此復云何？謂由煩惱對治故諸蘊畢竟不生。
——最簡形式：「滅即是離繫」（nirodha = visaṃyoga），「由煩惱對治」為擇滅之因，「諸蘊畢竟不生」為其果。此為前唯識之直接定義，尚無「究竟證會」之面向。
《大乘阿毘達磨雜集論》卷二（T31n1606, T31.0702c03–04，安慧釋《集論》）：
擇滅者，謂是滅是離繫，永害隨眠故。
——此措辭與 Asg 梵本 yo nirodho visaṃyogaḥ 為逐語素仿譯：「是滅是離繫」即 yo nirodho visaṃyogaḥ（「彼滅即是離繫」）。「永害隨眠」（anuśaya-prahāṇa）突出斷種子層次——非僅暫伏現行，乃從隨眠根本斷除。
《顯揚聖教論》卷一（T31n1602, T31.0484c03–04，無著菩薩造）：
擇滅者，謂由慧方便，有漏諸行畢竟不起，滅而是離繫性。
——無著於《顯揚》瑜伽行派-distinctively 展開：pratisaṃkhyā → 「慧方便」（prajñā-upāya），強調析擇之工具為般若；「畢竟不起」突出究竟性；「離繫性」（visaṃyoga）為本質。
《成唯識論》卷二（T31n1585, T31.0006c13–14，六無為假立論；「五依真如假立」框架全塊見 →#95 5-依真如假立框架已詳）：
由簡擇力，滅諸雜染，究竟證會，故名擇滅。
——《成唯識論》加入「究竟證會」——非僅斷除，且有「最終實現、親證」之義（近 darśana-mārga 與 bhāvanā-mārga 之果證），將擇滅提升為智慧現量與斷德之合一。此「五依真如假立」框架中，擇滅為「簡擇力所顯之真如面向」假立，非實有之單一滅法（→#100 真如承擔 the 統合者）。
按：論藏四層由淺入深：《大乘五蘊論》 之「滅即離繫」→ 《大乘阿毘達磨雜集論》 之「永害隨眠」→ 之「慧方便畢竟不起」→ 《成唯識論》卷二之「究竟證會」假立面向。擇滅非一次性之大滅，而是每一煩惱類別析擇所成之一個擇滅實例；阿羅漢已積累多個擇滅實例，其總和方近涅槃而非等同於涅槃——唯識之涅槃另有四重框架（有餘依／無餘依／無住處／本來自性清淨）（→#97 之形態反面）。
梵saṃskṛta
pratisaṃkhyā < prati-（向、各別、對應）+ sam-（完整）+ √khyā（見、說、計、審察）——「各別之精審」「逐一析擇」。同根 saṃkhyā（計數、數目；→#92 數）——但 prati- 前綴轉向「智慧之逐一審察」而非「計數之整體枚舉」。⚠️ 同名哲學宗派 Sāṃkhya（數論）亦源此根（「分析枚舉一切範疇」），與此處「智慧析擇煩惱」功能不同，而根相同。
nirodha < ni-（向下、入內）+ √rudh（阻止、止息）——「徹底之止息」（→#76 滅盡定同根）。
⚠ In Review · √khyā 與 √rudh 之印歐祖語同源，驗證報告未見確認鏈；不上推。
《阿毘達磨集論》（阿毘達磨-samuccaya，Pradhan 校本，asaṃskṛta-dharma 段，[Abhidh-s 13]）：
pratisaṃkhyā-nirodhaḥ katamaḥ / yo nirodho visaṃyogaḥ //
何為擇滅？即離繫之滅（yo nirodho visaṃyogaḥ — 「彼滅即是離繫」）。
此為 R.1 cessation-by-identity template（見 ASAMSKRTA §R.1）：Asg 以 yo X X 之恆等識別式定義——擇滅不是「另立一物以滅煩惱」，而是「nirodha 即 IS visaṃyoga」，兩詞指向同一實事之不同語言切入。此恆等形式本身即 prajñapti 性格之句法編碼：無為法無自體、無業用，只有結構恆等命名。
對偶比較（→#97 非擇滅為形態反面）：
| 無為 | Asg 梵本 | 恆等關係 | 漢語核心 |
|---|---|---|---|
| #96 擇滅 | yo nirodho visaṃyogaḥ | 滅 IS 離繫 | 由簡擇力，滅諸雜染 |
| #97 非擇滅 | yo nirodho na visaṃyogaḥ | 滅 IS NOT 離繫 | 不由擇力，緣闕所顯 |
a- 前綴之符號翻轉（#96 pratisaṃkhyā → #97 apratisaṃkhyā）為形態對偶，正如 #44 不信（āśraddhya）↔ #19 信（śraddhā）之 a- 取反同構（→#97 形態逆對）。
按：Asg 梵本「yo nirodho visaṃyogaḥ」之恆等式為本條之架構錨：擇滅不是修行所「生產」之新事物，而是修行所「揭示」之離繫事實之命名——《成唯識論》卷二之「究竟證會」即此「揭示」義之展開。三框架表（Asg／顯揚／《成唯識論》）之方法論樣板由 #95 梵段表鎖定，本條繼承（→#95；→#97 同框架繼承）。
巴pāḷi
於上座部阿毘達磨，擇滅無直接對應之獨立 asaṃkhata 範疇。南傳唯立 Nibbāna 為單一 asaṃkhata-dhamma（Vism XVI；Abhidhammattha-saṅgaha VI.34）。然擇滅於概念層次與 Nibbāna 最接近——兩者均涉及「經由般若斷除煩惱之滅」：
- 南傳路徑：在 magga-citta（道心）剎那，以 Nibbāna 為所緣（ārammaṇa）；每次道心剎那有一「見涅槃」之事——所見者為同一個 Nibbāna，非多個分別之滅。
- 瑜伽行派路徑：每一煩惱類別之析擇斷除各成一擇滅實例；阿羅漢積累多個擇滅實例。
兩者差異非內容之爭（均認可「經般若斷煩惱」此事），而是範疇架構之分歧：南傳將多次析擇斷煩惱之事收攝入單一 Nibbāna 之「所緣關係」（見 Nibbāna 之次數）；瑜伽行派將每次斷煩惱之事各立一個 pratisaṃkhyā-nirodha 實例。此為南北於 asaṃskṛta 詞族之架構設計差異，非 Nibbāna ≡ 擇滅之簡化等同（→#95 詞族之南北分歧框架）。
俟終校：Vism XVI.71 之 Pāli 原文精確措辭——驗證報告確認節參照，但未字元精準校勘原文；此處以節描述代替，不生成 Pāli 引文。
按：南傳之「多次道心見 Nibbāna」與瑜伽行派之「多個擇滅實例」為同一修行現象之兩種分類語言——南傳用「見涅槃之次數」表達，瑜伽行派用「每類煩惱各成一擇滅」表達；分類粒度不同，但均不否認析擇斷惑此事。南北此處之分歧小於 #97 非擇滅（#97 南傳完全無結構對應，→#97），而大於 #95 虛空之純 paññatti 層次分歧（→#95）。終極統合者為真如（→#100）。
漢綜述zh-synthesis
「擇滅」之梵文 pratisaṃkhyā-nirodha 為三形態合成：prati-（「向、各別、對應」）+ sam-（「完整」）+ √khyā（「見、說、計、審察」）= pratisaṃkhyā「各別精審、逐一析擇」；+ nirodha（ni-「下、入內」+ √rudh「阻止、止息」+ -a）。整體：「以逐一析擇為手段之止息」。√khyā 同根：saṃkhyā（計數）與哲學宗派 Sāṃkhya（數論，以分析枚舉一切範疇為方法）——本條之「析擇」為般若之智慧解析，非計數之整體枚舉。⚠️ √khyā 與 √rudh 之印歐祖語確認鏈未見，不上推。漢字「擇滅」：「擇」= pratisaṃkhyā 之析擇力，「滅」= nirodha 之止息——二字精準對應梵文兩要素。此為 6 無為之第二。
擇滅義理核心在《集論》 Asg 之恆等識別式定義（R.1 template）：yo nirodho visaṃyogaḥ（「彼滅即是離繫」）——擇滅不是「另立一物以滅煩惱」，而是「nirodha 即 IS visaṃyoga」之恆等命名；此為 prajñapti 性格之句法編碼（無為法無體無業，僅有結構恆等命名）。顯揚加入「慧方便」（prajñā-upāya）與「畢竟不起」，強調析擇工具（般若）與究竟性。《成唯識論》卷二再加「究竟證會」——非僅斷除，且有親證之義（近 darśana-mārga 與 bhāvanā-mārga 之果），將擇滅提升為智慧現量與斷德之合一。擇滅非一次性總滅，乃每一煩惱類別析擇各成一擇滅實例（阿羅漢積累多個）；此非等同涅槃（唯識四重涅槃另立框架）。於「五依真如假立」中，擇滅為「簡擇力所顯之真如面相」之假立命名（→#95 5-依真如假立框架已詳；→#100 承擔統合者）。
南傳唯立 Nibbāna 為 asaṃkhata（Vism XVI；Abhidhammattha-saṅgaha VI.34）。擇滅於南傳概念層最接近 Nibbāna——兩者均涉及「經般若斷惑之滅」。範疇架構差異：南傳之多次道心見 Nibbāna 以「同一個 Nibbāna 為所緣之次數」表達分析斷惑；瑜伽行派以「每類煩惱各成一擇滅實例」表達——同一修行現象之兩種分類語言，分類粒度不同，非對「析擇斷惑」此事本身之異議。此條目之南北分歧小於 #97 非擇滅（南傳完全無結構對應）。
禪修中之辨別要點：閉關環境中煩惱之不起，或為「因緣不具」（→#97 非擇滅）、或為「析擇斷種」（本條擇滅）——二者之判別在於「重遇同樣觸發境時，煩惱是否再起」：若再起，乃緣缺（#97）；若已斷根，乃析擇（#96）。每一析擇斷除均為確定之修行成就（visaṃyoga 不逆轉），道次第之粒度即此。
「擇滅」玄奘既譯，精準二字：「擇」（析擇力）+ 「滅」（止息）。英譯 Analytical cessation 為學界通行；by-wisdom-severance 或 discriminative cessation 亦見於部分文獻，然 Analytical cessation 較明 pratisaṃkhyā- 之逐一析擇義。
擇滅 ——於由簡擇力滅諸雜染之 dharmatā-面相中，假立「擇滅」（pratisaṃkhyā-nirodha）之名；性為簡擇力所滅雜染之究竟證會（離繫，visaṃyoga），業為析擇斷煩惱果之施設；不變不滅之究竟實，依真如（→#100）之簡擇所顯滅諦面相假立。
英綜述en-synthesis
Sanskrit pratisaṃkhyā-nirodha compounds three morphological elements: prati- (toward, against, each-respective), sam- (thorough, complete), and √khyā "to see, to recount, to discern analytically" — giving pratisaṃkhyā "thorough analytical discernment / case-by-case examination." The nirodha half: ni- (down, into) + √rudh "to obstruct, to block" → "cessation, thorough-stopping." The compound as a whole: "cessation through case-by-case analytical discernment." The root √khyā is shared with saṃkhyā (→#92 數 "numeration, count") and names the Sāṃkhya philosophical school (analytical enumeration of all categories of existence). The pratisaṃkhyā of this entry denotes prajñā's specific analytical function of discriminating the defiled from the undefiled kleśa-by-kleśa — the Sāṃkhya school uses the same root for a broader metaphysical enumeration of prakṛti's evolutes. Same root, divergent analytical projects. No secure PIE chain for √khyā or √rudh has been established in the verification record; no PIE reconstruction is advanced here.
Pratisaṃkhyā-nirodha is the second of six unconditioned dharmas (asaṃskṛta) in the Yogācāra 100-list, and the first of the four cessation-dharmas (#96–#99). Asaṅga's Abhidharma-samuccaya defines it by identity rather than predication: yo nirodho visaṃyogaḥ — "the cessation that IS dissociation-from-bonds." The Sanskrit copula-identification (R.1 cessation-by-identity template) encodes a key doctrinal point: pratisaṃkhyā-nirodha is not a produced thing, not an event with a cause-effect structure; it is a designation (prajñapti) imputed on the dissociation-fact when a kleśa-class has been analytically severed. One analytical severance yields one instance; an arhat has accumulated many (one per kleśa-class severed). Doctrinal precision: this is NOT equivalent to nirvāṇa. Yogācāra's nirvāṇa is a separate four-fold scheme (有餘依涅槃 / 無餘依涅槃 / 無住處涅槃 / 本來自性清淨涅槃) that overlays and contextualizes the six unconditioneds; pratisaṃkhyā-nirodha is the specific per-kleśa cessation designation, not the culminating nirvāṇa-fact. Cheng Weishi Lun fascicle 2 adds the experiential dimension absent from Asg's terse formula: 「由簡擇力，滅諸雜染，究竟證會」 — "by analytical-discrimination power, all defilements extinguished, ultimately realized" — pointing toward the darśana-mārga and bhāvanā-mārga realization aspect, not just the cessation-event.
Among the four cessation-dharmas, #96 alone has a partial Theravāda conceptual neighbor: Nibbāna is reached through analytical cessation of kilesa (paññā-based), and in that sense both traditions share the "cessation-through-wisdom" structural claim. But the categorial architecture diverges sharply: Theravāda's Nibbāna is one unconditioned dharma reached at one magga-citta moment (or re-realized at subsequent path-moments with the same Nibbāna as object); Yogācāra's pratisaṃkhyā-nirodha distributes into many instances (one per kleśa-class), accumulated over the path. Theravāda condenses the many severances into one Nibbāna-ārammaṇa; Yogācāra distributes them across many nirodha-instances. The Sarvāstivāda tradition (within whose orbit Yogācāra emerged) had already enumerated 擇滅 and 非擇滅 as two of its three unconditioneds; Yogācāra extended Sarvāstivāda's framework, while Theravāda reduced it. Structural chart: Sarvāstivāda 3 asaṃskṛta → Theravāda 1 (reduction) vs. Yogācāra 6/8 (extension) — both moving from the same Sarvāstivāda baseline in opposite directions (→#95 cluster divergence framework; →#100 unifier role).
The meditation-hall risk for #96 lies in two opposite errors. The first: mistaking apratisaṃkhyā-nirodha (mere non-arising due to absent conditions, #97) for pratisaṃkhyā-nirodha (actual analytical severance). Retreatants in a closed environment notice that aversion and craving are quiet — and conclude they have severed them. They have not; the anuśaya (seeds) remain intact, needing only the right conditions to manifest. The diagnostic: "Would encountering the same trigger-situation produce the same mental state?" If the kleśa re-arises on encountering its conditions, it was condition-absence (#97), not analytical-severance (#96). The second error: equating each realized pratisaṃkhyā-nirodha instance with nirvāṇa itself. CWS warns against this via the four-fold nirvāṇa scheme. Each analytical cessation is a real accomplishment — a visaṃyoga that does not reverse — but the accumulation of all such cessations is not yet the unconditioned principle (tathatā, →#100) that underlies them all. The practitioner's seam is the granularity of the path: each kleśa-class severed is a confirmed gain; the path is not won all at once.
Analytical cessation (pratisaṃkhyā-nirodha) — The cessation that IS dissociation-from-bonds (visaṃyoga): not a produced thing but a designation imputed on the fact of analytical severance when a kleśa-class is cut at the root by wisdom-discrimination. Each severance yields one instance; an arhat accumulates many. Not equivalent to nirvāṇa (which is a separate four-fold unconditioned scheme): analytical cessations are the granular achievements on the path that point forward to tathatā (#100) as the underlying principle on which all five cessation-designations rest.
