Achintya-Bheda-Abheda is a school of Vedanta representing the philosophy of inconceivable one-ness and difference. In Sanskrit achintya means 'inconceivable', bheda translates as 'difference', and abheda translates as 'non-difference'.

Shuddadvaita is the "purely non-dual" philosophy propounded by the Hindu philosopher Vallabha, the founder of Puṣṭimārga, a Vaishnava tradition focused on the worship of the deity Krishna. Vallabhacharya's pure form (nondualist) philosophy is different from Advaita.
