Biography Sri Raghavendra Swami was born as Venkatanatha in the town of Bhuvanagiri, Tamil Nadu into a Deshastha Madhva Brahmin family of Gautama Gotra of musicians and scholars after blessings from Lord Venkateshwara. His great-grandfather Krishna Bhatta was a tutor to the Vijayanagara king Krishnadeva Raya, his grandfather was Kanakachala Bhatta and his father Thimmanna Bhatta (also known as Thimmannacharya) was an accomplished scholar and musician. After the fall of the Vijayanagara empire, Thimmanacharya migrated to Kanchi with his wife Gopikamba. Venkatanatha had two siblings—Gururaja and Venkatamba. Venkatanatha's education was taken care of by his brother-in-law Lakshmi Narasimhacharya at Madurai after the early demise of his father, and he subsequently got married. In 1624, Raghavendra Tirtha became peetadhipathi of Kumbhakona Matha, which is now known by the name of Raghavendra Matha. After a short stay at Kumbakonam, he went on a pilgrimage to Rameshwaram, Ramnad, Srirangam, and Mathura. Later, he moved westwards to Udupi and Subramanya, and then to Pandharpur, Kolhapur and Bijapur. At Kolhapur, he is said to have stayed for a long time and at Bijapur, he supposedly defeated many Advaitins and converted them to Dvaita fold. After that, he returned to Kumbakonam. By 1663 he left for Mysore where he got a grant from Dodda Devaraya Odeyar. Finally, he chose to settle down in Mantralayam Raghavendra Swami took Samadhi in 1671 in Mantralayam, a village on the bank of river Tungabhadra in Adoni taluk in Andhra Pradesh. Works Forty works have been attributed to Sri Raghavendra swamy. Sharma notes that his works are characterised by their compactness, simplicity and their ability to explain the abstruse metaphysical concepts of Dvaita in understandable terms. His Tantradipika is an interpretation of the Brahma Sutra from the standpoint of Dvaita incorporating elements from Jayatirtha's Nyaya Sudha, Vyasatirtha's Tatparya Chandrika and the glosses by
