Mbh 1.95.11

“Thus have I, O king, recited the history of the descendants of Puru and of the Pandavas. This excellent, virtue-increasing, and sacred history should ever be listened to by vow-observing Brahmanas, by Kshatriyas devoted to the practices of their order and ready to protect their subjects; by Vaisyas with attention, and by Sudras with reverence, whose chief occupation is to wait upon the three other orders. Brahmanas conversant in the Vedas and other persons, who with attention and reverence recite this sacred history or listen to it when recited, conquer the heavens and attain to the abode of the blessed. They are also always respected and adored by the gods, Brahamanas, and other men. This holy history of Bharata hath been composed by the sacred and illustrious Vyasa. Veda-knowing Brahmanas and other persons who with reverence and without malice hear it recited, earn great religious merits and conquer the heavens. Though sinning, they are not disregarded by any one. Here occurs a sloka, ‘This (Bharata) is equal unto the Vedas: it is holy and excellent. It bestoweth wealth, fame, and life. Therefore, it should be listened to by men with rapt attention.’”
