Mbh 1.2.6

‘O Saunaka, this best of narrations called Bharata which has begun to be repeated at thy sacrifice, was formerly repeated at the sacrifice of Janamejaya by an intelligent disciple of Vyasa. It is divided into several sections; in the beginning are Paushya, Pauloma, and Astika parvas, describing in full the valour and renown of kings. It is a work whose description, diction, and sense are varied and wonderful. It contains an account of various manners and rites. It is accepted by the wise, as the state called Vairagya is by men desirous of final release. As Self among things to be known, as life among things that are dear, so is this history that furnisheth the means of arriving at the knowledge of Brahma the first among all the sastras. There is not a story current in this world but doth depend upon this history even as the body upon the foot that it taketh. As masters of good lineage are ever attended upon by servants desirous of preferment so is the Bharata cherished by all poets. As the words constituting the several branches of knowledge appertaining to the world and the Veda display only vowels and consonants, so this excellent history displayeth only the highest wisdom.
