The Purāṇas are a large class of Sanskrit texts, traditionally eighteen major and many minor, compiled over the first millennium CE and later. They recount the creation and dissolution of worlds, the genealogies of gods and kings, and the deeds of Viṣṇu, Śiva and the Goddess, and they teach devotion. Among the most influential is the Bhāgavata Purāṇa.
