Sadh Vaishnavism
Sadh Vaishnavism (Sanskrit: सद्वैष्णवसम्प्रदाय;), also referred to as Madhva Vaishnavism, the Madhva Sampradaya, or Tattvavada, part of the Brahma Sampradaya, is a denomination within the Vaishnavism—Bhagavata tradition of Hinduism. Sadh Vaishnavism was founded by the thirteenth century philosopher-saint Madhvacharya, who developed the Tattvavada (Dvaita Vedanta) ("arguments from a realist viewpoint") sub-school of Vedanta in Hindu philosophy.
