Devi Bhagavatam (Devi Puranam)
THE FIFTH SKANDHA
Chapter I
On the superiority of Rudra over Visnu
1-5. The Risis said :-- “The great legendary story, the life of S’rî Krisna, supremely divine, destructive of all sins, has been narrated by you, O Sûta! But, O Blessed One! You, though highly intelligent, have dwelt on it not at a great length; hence many doubts are cropping up in our minds. A very difficult tapasyâ was performed by Vâsudeva the part incarnate of Visnu, who had to go to forest to worship S’iva. Next, it has been known that the Devî Pârvatî, the part incarnate of the Great Mother, the Mother of the universe, the Supreme, and Perfect offered boons to S’rî Krisna. How did it then come to pass that S’rî Krisna, being himself the God, had to worship Pârvatî and Mahâdeva? Is it that S’rî Krisna was inferior to Mahâdeva and Pârvatî? This is our doubt.”
