(1197/9?–1276, alt. 1238–1317)
The founder of the Vaiṣṇava, Dvaita Vedānta sampradāya. Hagiographies claim that he was born in Udipi (Udupi) in Karnataka, but later travelled around India, teaching and disputing with other traditions, before returning to establish a maṭha in his home town. Initiated as an Advaitin, he came forcibly to reject Śaṅkara's teachings (in the process acknowledging the mythical Vyāsa as his only guru), and developed a dualistic, Kṛṣṇa- bhakti-oriented form of Vedānta, partially derived from his exegesis of texts such as the Mahābhārata and the Bhāgavata Purāṇa, on both of which he wrote commentaries. Credited with 37 works in all, his principal philosophical treatises are his commentaries (Bhāṣya and Anuvyākhyāna) on the Brahmasūtra(s). He also regarded Pāñcarātra texts as authoritative, particularly in matters of temple ritual.
