O brāhmaṇa, authorities on the matter understand a Purāṇa to contain ten characteristic topics: the creation of this universe, the subsequent creation of worlds and beings, the maintenance of all living beings, their sustenance, the rule of various Manus, the dynasties of great kings, the activities of such kings, annihilation, motivation and the supreme shelter. Other scholars state that the great Purāṇas deal with these ten topics, while lesser Purāṇas may deal with five.
