Ramanuja (traditionally, 1017–1137 CE) was a theologian, philosopher, and scriptural exegete, born in a Tamil Brahmin family in the village of Sriperumbudur, Tamil Nadu. He is also known as Sri Ramanujacharya, Udayavar,Ethirajar (Yatiraja), Emberumannar and Lakshmana Muni.  He is seen by Sri Vaishnavism as the most important acharya (teacher) of their tradition who followed Nathamuni and Yamunacharya, and by devottes in general as the leading expounder of Vishishtadvaita, one of the classical interpretations of the dominant Vedanta school of Vedic philosophy.
