One of a large number of so-called celestial buddhas known to Mahāyāna Buddhists in India during the first millennium, Akṣobhya was believed to inhabit a paradise-like world system far to the east, known as Abhirati (extreme delight). Bodhisattvas reborn there could make rapid progress toward buddhahood, while śrāvakas could achieve arhatship within a single life. Belief in Akṣobhya appears to have emerged in India around the beginning of the first millennium c.e. and spread widely in Buddhist communities before being eclipsed by the growing popularity of Amitābha. Today Akṣobhya is known mainly as one of the five directional buddhas who appear in tantric ritual texts.
