The Full Form of BAPS is‍ Bochasanwasi Akshar Purushottam Sanstha.

Bochasanwasi Akshar Purushottam Swaminarayan Sanstha (BAPS) (IAST: Bocāsaṇvāsī Akṣhar Puruṣottam Swaminarayan Sansthā), is a Hindu denomination within the Swaminarayan Sampradaya. It was formed by Yagnapurushdas (Shastriji Maharaj) on the principle that Swaminarayan was to remain present on earth through a lineage of gurus dating all the way back to Gunatitanand Swami – one of Swaminarayan’s most prominent disciples. Based on the Akshar Purushottam doctrine (also known as Akshar-Purushottam Darshan), followers of BAPS believe Swaminarayan manifests through a lineage of Aksharbrahman Gurus, beginning with Gunatitanand Swami, followed by Bhagatji Maharaj, Shastriji Maharaj, Yogiji Maharaj, Pramukh Swami Maharaj, and presently Mahant Swami Maharaj. As of 2019, BAPS has 44 shikharbaddha mandirs and more than 1,200 mandirs worldwide that facilitate practice of this doctrine by allowing followers to offer devotion to the murtis of Swaminarayan, Gunatitanand Swami, and their successors. BAPS mandirs also feature activities to foster culture and youth development. Many devotees view the mandir as a place for transmission of Hindu values and their incorporation into daily routines, family life, and careers. BAPS also engages in a host of humanitarian and charitable endeavors through BAPS Charities, a separate non-profit aid organization which has spearheaded a number of projects around the world addressing healthcare, education, environmental causes, and community-building campaigns
