Vaidalyaprakaraṇa

Overview

The Vaidalyaprakaraṇa (“Crushing the Categories”, ཞིབ་མོ་རྣམ་འཐག་, “Pulverisation Treatise”) is the fifth member of the Yukti-corpus (rigs pa’i tshogs drug) traditionally ascribed to Nāgārjuna. The Sanskrit original is lost; the text survives only in Tibetan translation by Jayānanda and Kudo Dewar (preserved in the Tengyur, D 3826/3830). It exists in two related forms: a shorter root text, the Vaidalyasūtra (VS, 72 sūtras in Pema Dorje’s count, 73 in Tola & Dragonetti, 74 in Westerhoff’s revision), and a longer version, the Vaidalyaprakaraṇa proper (VP), which embeds the VS in an autocommentary. Both are in prose — unusual for an Indian śāstra. Per Westerhoff (westerhoff-vaidalyaprakarana-2018) the VS and VP cannot be cleanly separated as root and commentary in the standard way: several VS sūtras (e.g. VS 04–05) are unintelligible without the commentarial context.

The text is dedicated entirely to refuting the sixteen categories (padārtha) of the Naiyāyika system as set out in the Nyāyasūtra: pramāṇa (epistemic instruments), prameya (epistemic objects), saṃśaya (doubt), prayojana (purpose), dṛṣṭānta (example), siddhānta (established conclusion), avayava (members of a syllogism), tarka (reductive reasoning), nirṇaya (determination), vāda (debate), jalpa (sophistical disputation), vitaṇḍā (cavil), hetvābhāsa (pseudo-reason), chala (equivocation), jāti (false rejoinder), nigrahasthāna (grounds of defeat). It is the most sustained engagement with non-Buddhist realist epistemology in the Nāgārjunian corpus.

Authenticity

Among the Yukti-corpus texts the VP is the most contested in modern scholarship. The colophons identify Nāgārjuna as the author; Bhāviveka (in the Madhyamakaratnapradīpa, though that ascription is itself debated) and Candrakīrti (Madhyamakaśāstrastuti) cite the VP as Nāgārjuna’s work. Kajiyama 1965, Lindtner 1982, Ruegg 1981, Yamaguchi 1944, and Williams 1978 accept it as authentic; Tola & Dragonetti 1995 and Pind 2001 raise doubts. Westerhoff defends authenticity (westerhoff-vaidalyaprakarana-2018) on the grounds that (i) Tola & Dragonetti’s parallel-with-Yogācāra arguments cannot exclude the alternatives that the parallel runs the other way, derives from a common predecessor, or is independent; (ii) Pind’s claim that VP 58 is incompatible with Madhyamaka rests on a contested emendation. The wiki treats the VP as Nāgārjuna’s, following both the Indian and Tibetan tradition and the majority of modern scholarship.

Aim and place in the Nāgārjunian corpus

Per Tsong Khapa’s Rigs pa’i rgya mtsho (cited Thurman in westerhoff-vaidalyaprakarana-2018 Publisher’s Preface), the three core Nāgārjunian works form a logical triad:

1. The Mūlamadhyamakakārikā refutes the probandum — the intrinsic nature of persons and phenomena that the substantialists wish to prove.
2. The Vaidalyaprakaraṇa refutes the probans — the sixteen Naiyāyika logical categories used to prove that intrinsic nature.
3. The Vigrahavyāvartanī then defends the conventional validity of the Mādhyamika’s own use of refutation and proof against the implication that the prior critique self-destructs.

This sequencing places the VP between MMK and VV both topically and logically. Westerhoff endorses this reading.

The aim of the VP is two-level. Ultimately, refute the foundationalist Naiyāyika construal of the categories: each one presupposes intrinsic nature (རང་བཞིན་, svabhāva) somewhere — in pramāṇas that establish themselves, in similarity relations that hold “out there,” in temporal relations between reason and conclusion that exist independently of conceptual construction. Conventionally, preserve a Madhyamaka-compatible, svabhāva-free version of the same categories, since otherwise the Mādhyamika has no argumentative resources left. Per westerhoff-vaidalyaprakarana-2018 (Introduction, “The Aim”): “A suitably desubstantialised variant of the Nyāya categories, Nāgārjuna argues, may still be retained.”

The Tibetan tradition (Maja Changchub Tsöndru, Tsong Khapa) reads the VP as the answer to a specific opponent: if things are established by reliable epistemic instruments, they have intrinsic nature. By showing that the pramāṇas themselves are not reliably established, the inference from pramāṇa-establishment to svabhāva fails — and the threat to the Madhyamaka thesis of universal emptiness from Nyāya foundationalism is neutralised.

Structure (Westerhoff’s synopsis)

74 sūtras grouped by Naiyāyika category:

1. Introduction (01) — rejection of the sixteen Nyāya categories for the proponent of emptiness.
2. Pramāṇa (02–20) — the longest section. Mutual dependence of pramāṇa and prameya (02); not self-established (03); dependent existence rules out svabhāva (04); the regress argument (05); the self-illuminating-light analogy and its dismantling (06–11); temporal-relation problems (12–15); the negation of pramāṇas as themselves a coherent operation (14–16); secondary critiques of correct knowledge, pots-as-objects, and mental cognitions (17–20).
3. Saṃśaya (21–23) — doubt cannot be directed at conceived or non-conceived objects.
4. Prayojana (24) — purpose can be neither existent nor nonexistent.
5. Dṛṣṭānta (25–31) — examples; concordant and discordant examples both fail; no similarity relation exists svabhāva-independently.
6. Siddhānta (32) — established conclusion fails for the same reason as anta in dṛṣṭānta.
7. Avayava (33–49) — members of a syllogism; the whole-and-parts problem; reasons generate regress; only one part of a syllogism can exist at a time (under momentariness).
8. Tarka (50) — reductive reasoning collapses with doubt.
9. Nirṇaya (51) — no determination, since neither thesis nor negation can be ultimately true.
10. Vāda (52–56) — debate fails because the relation between expression and referent is neither essential, conventional, identical, nor distinct.
11. Jalpa and Vitaṇḍā (57) — refuted as vāda.
12. Hetvābhāsa (58–62) — pseudo-reasons; Pind’s contested verse.
13. Viruddha (63–64) — contradiction.
14. Kālātīta (65–67) — mistimed reasons.
15. Chala (68) — equivocation; the opponent objects that Nāgārjuna only has paramārthatas in mind, sliding between conventional and ultimate; Nāgārjuna replies that this is “to be replied to” rather than equivocation.
16. Jāti (69) — false rejoinders fail because there is no production.
17. Nigrahasthāna (70–72) — grounds of defeat fail because there is no repetition or binding.
18. Conclusion (73–74) — rejecting the categories does not make it impossible to assert negations; expressions and referents do not exist (with the svabhāva-qualifier preserved at the conventional level).

Key passages (relevant to current paper)

• VP 01 — opens by rejecting the categories for the proponent of emptiness. Sets the two-level frame: the Mādhyamika does not accept the categories as ultimately real but uses them conventionally.
• VP 02–04 — the pramāṇa–prameya mutual-dependence argument. Direct primary-text anchor for the Pramāṇa anti-foundationalist line. Compressed and extended version of Vigrahavyāvartanī vv. 30–51.
• VP 05–11 — the regress argument and the dismantling of the self-illuminating-light analogy. The fire/light analogy is the same one Vigrahavyāvartanī vv. 34–39 dismantles; the VP version applies it to the full pramāṇa edifice.
• VP 47 — the reason either requires another reason (regress) or does not (begs the question). Westerhoff’s commentary stresses that this argument is not an internal logical defect of “reason” tout court — a non-foundationalist could happily accept that some reasons are not further-reason-grounded — but reveals that the argument only bites against a foundationalist Naiyāyika who insists every justified statement is grounded in a further justified statement. This is one of the cleanest places where the VP shows Madhyamaka critique as internal to the opponent’s substantialist framework.
• VP 52–56 — semantics. One thing denoted by many words; no essential connection between word and referent; expressions and referents neither identical nor distinct. Primary-text anchor for the convention-based semantics that Westerhoff also extracts from Vigrahavyāvartanī v. 29.
• VP 68 — opponent: there is equivocation, because Nāgārjuna only has ultimate existence in mind. Tola & Dragonetti read this passage as Nāgārjuna denying he has been arguing for the śūnyatā of the padārthas; Westerhoff disagrees and reads VP 68 as preserving the two-level structure (the padārthas are negated paramārthatas but retained at the conventional level). The reading at VP 68 is one of the load-bearing interpretive cruxes for whether the VP is or is not a “Madhyamaka” text in the standard sense.
• VP 73–74 — the conclusion: rejecting the categories does not abolish negation or assertion. Provides Nāgārjuna’s own statement that the desubstantialised use of the categories is preserved.

Place in the Yukti-corpus

The Yukti-corpus (rigs pa’i tshogs drug) — see Vigrahavyāvartanī for the full list — places the VP fifth, between Yuktiṣaṣṭikā and Ratnāvalī. The VP is methodologically distinctive within the corpus in three ways:

1. It targets a single non-Buddhist opponent (Naiyāyika) rather than the multiple Ābhidharmika and realist interlocutors of the MMK.
2. It is structured around the opponent’s own taxonomy (the sixteen categories), rather than around topics chosen by Nāgārjuna himself.
3. It has no extant Indian or Tibetan commentary. Vigrahavyāvartanī also lacks a named sub-commentary but is quoted extensively. The VP is quoted only sparsely (Lindtner notes “never noticed any quotation”; Maja Changchub Tsöndru’s MMK commentary cites VP 01). Westerhoff suggests this is because the VP requires close knowledge of the Nyāyasūtra, which was never translated into Tibetan.

Commentarial tradition

There is no full Indian or Tibetan commentary on the VP. The two known textual citations are (i) Maja Changchub Tsöndru’s twelfth-century commentary on the MMK, which quotes VP 01; (ii) Tsong Khapa’s Rigs pa’i rgya mtsho (Ocean of Reasoning), which characterises the VP as the probans-refuting partner of the probandum-refuting MMK. Bhāviveka’s Madhyamakaratnapradīpa and Candrakīrti’s Madhyamakaśāstrastuti mention the VP but do not comment on it. The absence of Indian-Tibetan commentarial elaboration is the single most striking feature of the VP’s reception history.

Modern reception

• Westerhoff (westerhoff-vaidalyaprakarana-2018, Wisdom / AIBS Treasury of the Buddhist Sciences) — the most recent and most philosophically sustained translation; defends authenticity; reads the VP as constructive anti-foundationalism; argues the VP precedes VV in Nāgārjuna’s logical sequence.
• Tola & Dragonetti (1995) — Nagarjuna’s Refutation of Logic (Motilal Banarsidass), the prior English translation; raises authenticity concerns; reads VP 68 as Nāgārjuna disclaiming the śūnyatā-argument, against Westerhoff.
• Kajiyama (1974) — Japanese translation; characterises the VP arguments as “sophistries”; Westerhoff rebuts on principle-of-charity grounds.
• Pind (2001) — argues VP 58 is incompatible with Madhyamaka and that the VP cannot be Nāgārjuna’s; Westerhoff disputes the emendation underlying the argument.
• Pema Dorje / Sempa Dorje (1974) — Sanskrit reconstruction of the VS based on the Tibetan; uses 72 sūtras.
• Yamaguchi (1944) — earlier Japanese translation.
