Vallabhacharya Telugu: వల్లబ్హాచార్య(1479–1531) was a devotional philosopher, who founded the Pushti sect inIndia, following the philosophy of Shuddha advaita (Pure Non-dualism).
Vallabhacharya accepted the 'Acharya' designation of Vishnuswami Sampraday (Rudra Sampraday) upon request of Bilvamangala Acharya, the last Vishnuswami Sampraday acharya before Vallabhacharya. This was after Vallabhacharya won the famous debate of Brahmavad over Shankars in the courtyard of the King Krishna Dev Ray of Vijaynagar - the prosperous South Indian Kingdom.
Apart from being the acharya of Vishnuswami Sampradaya, Vallabhacharya also propagated the Pushtimarg upon the god Krishna's order and thus became the acharya of not only Vishnuswami Sampraday but also Pushti Sampraday.
He is the Acharya and Guru within the Vaishnava traditions as promulgated and prescribed by the Vedantaphilosophy. He is associated with Vishnuswami, a prominent Acharya of Rudra Sampradaya out of the four Vaishnava Sampradayas. Within Indian Philosophy, he is known as the writer of Anubhashya - a commentary on Brahma Sutra, Shodash Granth or sixteen 'stotras' (tracts) and several commentaries on the Bhagavata Purana, which describes the many lilas (pastimes) of the Avatar, Krishna. Vallabha Acharya occupies a unique place in Indian culture as a scholar, a philosopher and devotional (bhakti) preacher. He is widely considered as the last of the four great Vaishnava Acharyas who established the various Vaishnava schools of thought based on Vedantic philosophy, the other three (preceding him) being Ramanujacharya, Madhvacharya and Nimbarkacharya. He is especially known as a lover and a propagator of Bhagavata Dharma. He was born in Champaranya in India.
