Swamiji i need a clarification on Puranas as there are 18 mahapuranas and few upapuranas given by Veda vyasa maharshi(who is an avatar of bhagawan vishnu) in which few puranas explain creation as made by Bhagawan vishnu and few puranas stating Creation came from Bhagawan Shiv and few puranas state creation came from Durga maata/Lakshmi maata.
I am studying different sampradayas in Sanatan dharma and few sampradayas outwrite say that except puranas related to Bhagawan vishnu remaining are not valid and same goes for followers of Bhagawan Shiv.
Can you give a clarification why Bhagawan Vishnu has given us these many puranas(As each puranas are written in different kalpa).
