Mahapuranas
Of the many texts designated 'Puranas' the most important are the Mahāpurāṇas or the major Puranas.[8] These are said to be eighteen in number, divided into three groups of six, though they are not always counted in the same way. The list of Mahapuranas is mentioned in the Vishnu Purana, part 3, chapter 6, verses 21–24.[31] The number of verses in each Mahapurana is mentioned in the Bhagavata Purana, part 12, chapter 13, verses 4–9.[32]
