Madhvacharya (1238–1317 CE), also known as Purna Prajña and Ananda Tīrtha, was an Indian philosopher who was the chief proponent of the Dvaita school of Vaishnavism and Tattvavada "the philosophy of reality". They have been generally referred to Vaishnava Brahmins who are followers of Lord Vishnu as their Supreme God, in this regard it is one of the few schools of Vaishnavism who adhere to the Vedic view of Supreme Godhead of Vishnu unlike the latter day sects who uphold one particular Avatar as Supreme form of Godhead on the basis of Puranas in contradistinction to Vedas. It is one of the three most influential Vedānta philosophies. Madhvācārya was one of the important philosophers during the Bhakti movement. He was a pioneer in many ways, going against standard conventions and norms. According to tradition, Madhvācārya is believed to be the third incarnation of Vāyu (Mukhyaprāna) and first two being Hanuman and Bhīma.
