Dvaita (द्वैत) is a Sanskrit word that means "duality, dualism, doubt". The term refers to any premise, particularly in theology on the temporal and the divine, where two principles (truths) or realities are posited to exist simultaneously and independently.
Dvaita also refers to a sub-school in Vedanta tradition of Hindu philosophy. Alternatively known as Bhedavāda, Tattvavāda and Bimbapratibimbavāda, Dvaita Vedanta sub-school was founded by the 13th-century scholar Madhvacharya. The Dvaita Vedanta school believes that God (Vishnu, supreme soul) and the individual souls ( jīvātman) exist as independent realities, and these are distinct. The Dvaita school contrasts with the other two major sub-schools of Vedanta, the Advaita Vedanta of Adi Shankara which posits nondualism – that ultimate reality ( Brahman) and human soul are identical and all reality is interconnected oneness, and Vishishtadvaita of Ramanuja which posits qualified nondualism – that ultimate reality ( Brahman) and human soul are different but with the potential to be identical.
