Madhwacharya

Reality is twofold: independent and dependent things. The Lord Vishnu is the only independent thing. Madhvacharya (IAST: Madhvācārya; Sanskrit pronunciation: ; CE 1199-1278 or CE 1238–1317), sometimes anglicised as Madhva Acharya, and also known as Purna Prajna (IAST: Pūrṇa-Prajña) and Ānanda Tīrtha, was an Indian philosopher, theologian and the chief proponent of the Dvaita (dualism) school of Vedanta. Madhva called his philosophy Tattvavāda meaning "arguments from a realist viewpoint".
