Madhvacharya, and also known as Purna Prajna 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".

Vedanta, also known as Uttara Mīmāṃsā, is one of the six orthodox (āstika) traditions of textual exegesis and Hindu philosophy. The word "Vedanta" means "conclusion of the Vedas", and encompasses the ideas that emerged from, or aligned and reinterpreted, the speculations and enumerations contained in the Upanishads, focusing on either devotion or knowledge and liberation. Vedanta developed into many traditions, all of which give their specific interpretations of a common group of texts called the Prasthānatrayī, translated as "the three sources": the Upanishads, the Brahma Sutras and the Bhagavad Gita.
