Prajñāpradīpa

Overview

The Prajñāpradīpa (Lamp of Wisdom, Tib. Shes rab sgron ma) is Bhāviveka’s word-by-word commentary on Nāgārjuna’s Mūlamadhyamakakārikā. It is the second great Indian MMK commentary after Buddhapālita’s Buddhapālitavṛtti, and the first to bring the formal apparatus of Buddhist logic to bear on the text (Dignāga-style probative syllogisms with thesis, reason, and example) and to engage rival Indian schools at length — Sāṃkhya, Vaiśeṣika, Jaina, grammarian, Yogācāra. Its method is polemical and regular: it quotes Buddhapālita’s commentary on a given verse, subjects that quotation to a short methodological critique, then advances its own autonomous syllogistic reformulation of Nāgārjuna’s argument, characteristically qualified by “in ultimate reality” (paramārthatas / don dam par).

Bhāviveka’s critique of Buddhapālita in Chapter 1 (the MMK 1.1 exchange) is the textual root of everything the Tibetan tradition later codified as the Prāsaṅgika-Svātantrika distinction (see Prāsaṅgika-Svātantrika). Candrakīrti’s Prasannapadā defence of Buddhapālita (candrakirti-prasannapada-mmk1-excerpt) answers the Prajñāpradīpa directly. Avalokitavrata (c. 7th c.) then wrote a vast sub-commentary, the Prajñāpradīpa-ṭīkā, which Tibetan translators rendered alongside the Prajñāpradīpa itself. Ames (1995: 296) describes the work as “the first commentary on the MMK to make use of the formal apparatus of Buddhist logic and the first to discuss non-Buddhist philosophical schools extensively.”

Key passages

• Chapter 1 (commentary on MMK 1.1, “Not from themselves and not from others…“): contains Bhāviveka’s three-pronged critique of Buddhapālita’s gloss. He charges that it lacks arguments and examples, that it does not dispel counter-criticisms, and that, since Buddhapālita’s words are consequential, they unwittingly imply arising-from-other. The chapter also contains his characteristic autonomous argument: “Ultimately, the inner sense sources can be ascertained to not arise from themselves, because they exist — just as in the case, for example, of an existent consciousness.” These passages survive in Candrakīrti’s verbatim quotation in candrakirti-prasannapada-mmk1-excerpt. Ames’s full translation of Chapter 1 appears in JIP 21 (1993) and JIP 22 (1994)
• Chapter 2 (commentary on MMK 2 — motion / “Examination of the Traversed, the Untraversed, and that which is being Traversed”; see ames-prajnapradipa-ch2-1995): a systematic conversion of Nāgārjuna’s prasaṅga arguments into formal syllogisms with the paramārthatas qualifier; responses to at least six rival schools; an explicit endorsement, at the conventional level, of a momentary Sautrāntika-style theory of motion; and chapter-closing Prajñāpāramitā sūtra citations (Aṣṭasāhasrikā, Suvikrāntavikrāmi, Ārya-brahma-viśeṣa-cintā-paripṛcchā, Ārya-akṣayamati-nirdeśa). The chapter also preserves several direct quotations of Buddhapālita absent from the Prasannapadā
• Chapters 3–5 were translated in Ames’s University of Washington PhD thesis (1986)
• Chapter 18 — Bhāviveka’s account of the two selflessnesses, cognate to the MA 1.8 Mahāyāna-distinctiveness debate
• Chapter 23 — the subject of Ames (1988), “The Soteriological Purpose of Nāgārjuna’s Philosophy”
• Chapter 25 — the nirvāṇa chapter

Surviving Indian commentarial corpus on MMK (per coghlan-buddhapalita-2021 Introduction, citing Saito 1984): the Prajñāpradīpa is one of only four MMK commentaries preserved in the Tibetan canon, alongside Nāgārjuna’s Akutobhayā, Buddhapālita’s BP, and Candrakīrti’s Prasannapadā. The Chinese canon preserves two further independent commentaries absent from Tibetan — Qingmu’s Zhonglun (T.D. 1824, possibly by Piṅgala) and Sthiramati’s Dasheng zhong guan shilun (T.D. 1567). Doxographical sources attest eight Indian MMK commentaries (the four above, plus Devasharman, Guṇaśrī, Guṇamati, Sthiramati); only six survive at all, and the Tibetan-transmitted corpus is the Mādhyamika-classified quartet. This selection bears on the question of a “unified Indian reception”: the prominence of the Prajñāpradīpa in Tibet reflects what survived translation and transmission, not an Indian consensus.

Commentarial tradition

• Avalokitavrata (c. 7th c.): massive Prajñāpradīpa-ṭīkā sub-commentary, extant only in Tibetan; quotes the entire Prajñāpradīpa and often paraphrases terse passages in ways that disambiguate the root text. Ames relies heavily on Avalokitavrata throughout the Chapter 2 translation
• Candrakīrti in the Prasannapadā treats the Prajñāpradīpa as the principal polemical target. See candrakirti-prasannapada-mmk1-excerpt sections II, IX, XI for his verbatim quotations
• Atiśa taught Bhāviveka’s Prajñāpradīpa and Madhyamakahṛdaya publicly while reserving Candrakīrti for advanced instruction — the synthesis-without-ranking view of Indian Madhyamaka documented in apple-jewels-middle-way-2018
• Tsongkhapa references the Prajñāpradīpa in tsongkhapa-illuminating-intent-1418 when presenting the Svātantrika position pedagogically via Kamalaśīla’s Light of the Middle Way

Modern reception

• Tibetan editions consulted by Ames (1995): Peking, Narthang, Derge, Cone. The translation is by Jñānagarbha and Cog ro Klu’i rgyal mtshan (early 9th c.) and is regarded as excellent
• Chinese translation: “reportedly rather poor” (Kajiyama 1963; Ames 1995: 297)
• English translations by William L. Ames:
  • Ch 1 Part One — JIP 21 (1993): 209–259
  • Ch 1 Part Two — JIP 22 (1994): 93–135
  • Ch 2 — JIP 23 (1995): 295–365 (see ames-prajnapradipa-ch2-1995)
  • Chs 3–5 — in Ames (1986), University of Washington PhD thesis
• Ruegg (1981) discusses the Prajñāpradīpa as the textual origin of the methodological dispute Tibet later codified as Prāsaṅgika-Svātantrika; this analysis is deepened in ruegg-svat-pras-2006
