Vyasatirtha

Vyasatirtha (1447–1539), born Yatiraja, was a Hindu philosopher and saint of Madhva's Dvaita school of Vedanta. Ordained in his youth, he succeeded Bramhanya Tirtha as pontiff at Abbur in 1478, then studied under Sripadaraja at Mulbagal.

As rajaguru of the Vijayanagara Empire he advised Kings Saluva Narasimha and Krishna Deva Raya, and was honoured as one of the three great saints of Dvaita. His works such as the Nyayamruta dissected rival philosophies.

He developed irrigation at Bettakonda and established temples in newly conquered regions. His Kannada and Sanskrit devotional songs such as Krishna Nee Begane shaped the Haridasa movement.
