Dà-yù-lóng púsà 大域龍菩薩 (*Dignāga, “Direction-Elephant”; the more usual Chinese name is 陳那 Chénnà; conventionally c. 480–540 CE), Indian Buddhist Yogācāra master, founder of the Buddhist pramāṇa (epistemology) tradition. Per the standard Indic-Buddhist hagiography (the Dìngāo púsà zhuàn 提婆菩薩傳 / Tibetan biographies), Dignāga was a brāhmaṇa-born native of southern India (Kāñcī), Vasubandhu’s disciple, who founded the Buddhist epistemological tradition with the Pramāṇasamuccaya and related works. He is also recognized as a major prajñāpāramitā commentator: his Prajñāpāramitā-piṇḍārtha-saṃgraha (“Compendium of Prajñāpāramitā Topics” = T1518) is the foundational verse-summary of the Aṣṭasāhasrikā Prajñāpāramitā in the late-Indic Mahāyāna tradition.
The unusual Chinese name 大域龍 is a calque-rendering of Dignāga (dik = “direction, region” → 大域; nāga = “elephant, dragon” → 龍), distinct from the more usual transliteration 陳那 (Chen-na ≈ Skt cīna / cinta). The 大域龍 form is preserved in the Northern-Sòng Yìjīngyuàn signatures. Per DILA Buddhist Person Authority A001255.
