Madhvacharya (1238-1317) was the chief propounder of the Dvaita or dualistic school of Hindu philosophy, one of the three influential Vedanta philosophies. He was one of the important philosophers during the Bhakti movement. Madhvacharya is believed to be the third incarnation of Vayu, aka MukhyaPrana, after Hanuman and Bhima.
Shri Madhvacharya, espoused a Vaishnava Theology that understands Brahman as endowed with attributes and as a personal God, Vishnu. By Brahman, he referred to the infinite, immanent and transcendent Utimate Reality and not the sub-caste.
