puranas manupulated by bengalis

 Some puranas were manupulated by bengalis after 1000 ce and this manupulation continued till 16th century.The main manuscripts were kept in bengal,and bengali vaishnavas have altered them to make vishnu appear superior to shiva.There are many examples.Padma purana has many fake verses.That verse about the classification of puranas as satvik,tamasic is well known.This is added later by bengali vaishnvas.Some verses were added to condemn certain historic personalities.
Bhagavata has many fake chapters.Shiva going to vishnu and asking him to show mohini's avatar and vishnu showing mohini as a beautiful woman on earth and getting naked,shiva getting excited and running after mohini are all created by begali vaishnavas.Bhagavata has only nine chapters.Bhagavata  might have ended with gajendra moksha or with parashurama avatar.The rest is all fake and added later.The remaining chapters were added after krishna was made god.Bhagavata was written before mahabharata was written.First Rama the king was made god,and then krishna was made god.Shivapurana,Bhagavata,vishnu purana and some puaranas were written before mahabharata was written around 800 bc.Some puranas were written after mahabharata was written.
