Shuddadvaita (Sanskrit: śuddhādvaita "pure non-dualism") is the "purely non-dual" philosophy propounded by Vallabhacharya (1479-1531 CE), the founding philosopher and guru of the Vallabhā sampradāya ("tradition of Vallabh") or Puśtimārg ("The path of grace"), a Hindu Vaishnava tradition focused on the worship of Krishna. Vallabhacharya's pure form (nondualist) philosophy is different from Advaita.
