The Vayu Purana - The Vayu Purana itself states that the Puranas were originally recited by the great god Brahma and that one has to understand the Puranas if one is to appreciate the Vedas and the Upanishadas. A person who has learnt the Vedas and the Upanishadas, but has not bothered to study the Puranas, can never be wise. The knowledge of the Puranas supplements that of the Vedas and the Upanishadas. As such, the Puranas contain many stories and history. There is no race on earth that does not have its own history. But the immense volume of the Puranas is unsurpassed anywhere else in the world.
