"Vallabhacharya Mahaprabhu (1479–1531 CE), also known as Vallabha and Vishnuswami, or Vallabha Acharya Mahaprabhu, is an Hindu Indian saint and philosopher who founded the Krishna-centered PushtiMarg sect of Vaishnavism in the Braj region of India, and the vedanta philosophy of Shuddha advaita (Pure Non-dualism).

Vallabhacharya (acarya, “teacher”) himself belonged to the Rudra sect established by Vishnusvamin, and his philosophical system of pure nondualism (shuddhadvaita)—i.e., the identity of God and the universe—closely follows that of the Vishnusvamin tradition.

Is Vallabhacharya incarnation of Krishna?
His legacy is best preserved with the acharyas of his Pushtimarg Vallabh Sampraday, also in the Braj region, and particularly at Nathdwara in Mewar region of India – an important Krishna pilgrimage center. He is regarded as an incarnation of Agni (Vaishwanar Agni Swaroop of Shri Krishna's face).
