"Vishnu Purana is one of the eighteen traditional puranas, which were an important genre of smriti text, and the repository of much of traditional Indian mythology... Most of the puranas are highly sectarian as is the Vishnu Purana which is focused on the worship of Vishnu. It gives an exhaustive account of Vishnu’s mystic deeds – many of which have become the common mythic currency for many traditional Hindus – as well as instructions for how, where, and when Vishnu is to be worshipped."
