Lóngshù púsà 龍樹菩薩 (*Nāgārjuna; conventionally c. 150–250 CE), Indian Buddhist Mādhyamika master, founder of the Mādhyamaka philosophical tradition and the most consequential Indic Mahāyāna śāstra-author. Per traditional hagiography (the Lóngshù púsà zhuàn 龍樹菩薩傳, T2047, attributed to Kumārajīva, and Tibetan parallels), Nāgārjuna was born in southern India (Vidarbha or Andhra) and was the principal Buddhist philosopher of the Sātavāhana court.
His foundational philosophical works are the Mūlamadhyamakakārikā (中論本頌) — the founding text of Mādhyamaka — and the Yuktiṣaṣṭikā, Śūnyatāsaptati, Vigrahavyāvartanī, and other shorter treatises; in addition, much of Indic and East-Asian Buddhist tradition attributes to him the Daśabhūmikavibhāṣā, the Suhṛllekha, the Ratnāvalī, and the immense Mahāprajñāpāramitāśāstra / [[KR6c0005|Dà-zhì-dù lùn 大智度論 (T1509)]] — the principal commentary on the Pañcaviṃśatisāhasrikā Prajñāpāramitā. Modern scholarship is divided on whether T1509 is genuinely Nāgārjuna’s or a later compilation by Kumārajīva’s circle drawing on Mādhyamika and Sarvāstivādin Abhidharma material; see the T1509 entry for discussion.
