Akshar-Purushottam Darshan or Aksarabrahma-Parabrahma-Darsanam, "Akshar-Purushottam philosophy," is a designation used by BAPS as an alternative name for the Swaminarayan Darshana, Swaminarayan's view or teachings, to distinguish it from other Vedanta-traditions. It is based on Swaminarayan's distinction between Parabrahman and Aksharbrahman as two distinct eternal realities, which in this view sets Swaminarayan's teachings apart from other Vedanta-traditions. It is an essential element for the BAPS and its Akṣara-Puruṣottama Upāsanā ("worship"), in which Purushottam c.q. Parabrahman is present in a lineage of Aksharbrahman guru's, who are the abode (akshar) of God.

Bochasanwasi Akshar Purushottam Swaminarayan Sanstha is a Hindu denomination within the Swaminarayan Sampradaya. It was formed in 1905 by Yagnapurushdas following his conviction that Swaminarayan remained present on earth through a lineage of gurus starting with Gunatitanand Swami. As of August 2016, Mahant Swami Maharaj is the 6th guru and president of BAPS.
