Ramanuja

Śrī Ramanuja (traditionally 1017–1137, also known as Śrī Ramanujacharya, Udayavar, Ethirajar (Yatiraja), Emberumannar, Lakshmana Muni) was a theologian, philosopher, and scriptural exegete. He is seen by Śrīvaiṣṇavas as the most important teacher (ācārya) of their tradition who followed Nathamuni and Yamunacharya, and by Hindus in general as the leading expounder of Viśiṣṭādvaita, one of the classical interpretations of the dominant Vedanta school of Hindu philosophy.
