Dvaita was propounded by Madhvacharya (1238–1317 CE). He presented the opposite interpretation of Shankara in his Dvaita, or dualistic system. In contrast to Shankara's non-dualism and Ramanuja's qualified non-dualism, he championed unqualified dualism. Madhva wrote commentaries on the chief Upanishads, the Bhagavad Gita and the Brahma Sutra.
Madhva started his Vedic studies at age seven, joined an Advaita Vedanta monastery in Dwarka (Gujarat), studied under guru Achyutrapreksha, frequently disagreed with him, left the Advaita monastery, and founded Dvaita. Madhva and his followers Jayatirtha and Vyasatirtha, were critical of all competing Hindu philosophies, Jainism and Buddhism, but particularly intense in their criticism of Advaita Vedanta and Adi Shankara.
Dvaita Vedanta is theistic and it identifies Brahman with Narayana, or more specifically Vishnu, in a manner similar to Ramanuja's Vishishtadvaita Vedanta. But it is more explicitly pluralistic. Madhva's emphasis for difference between soul and Brahman was so pronounced that he taught there were differences (1) between material things; (2) between material things and souls; (3) between material things and God; (4) between souls; and (5) between souls and God. He also advocated for a difference in degrees in the possession of knowledge. He also advocated for differences in the enjoyment of bliss even in the case of liberated souls, a doctrine found in no other system of Indian philosophy.
