"Tell me, greatest of Dvijas, what would you hear from me? Shall I recount the sacred tales of the Puranas, which tell of dharma and artha, or shall I tell you about the deeds of enlightened Rishis and of the kings of men?’ The Rishis replied, ‘The Purana that was first propounded by the great Dwaipayana. When both the Devas and the Brahmarishis had heard it, they said it was the foremost of all Itihasas, histories. It varies in both diction and divisions, has intricate and subtle meanings, logically combined and gleaned from the Vedas, and it is a most holy work. It is composed in elegant language and includes the subjects of every other book. Other Shastras elucidate this Purana, and it reflects the inmost meaning of the four Vedas. We want to listen to that Itihasa, which is also called the Bharata, the magnificent Vyasa’s holy masterwork, which dispels the fear of evil. We would hear it exactly as the Rishi Vaisampayana told it, joyously, under the direction of Dwaipayana himself, at the sarpa yagna, the snake-sacrifice of Raja Janamejaya.’"
