"Most of the puranas are highly sectarian as is the Shiva Purana, which is one of the longer and larger puranas. It gives an exhaustive account Shiva’s mythic deeds – many of which have become the common mythic currency for many traditional Hindus – as well as instructions for how, where, and when Shiva is to be worshipped."
