When Vyāsa was engaged by Brahmā in the work of arranging the Vedas, he took four persons, proficient in these works, as his disciples. He appointed Paila reader of the Rich; Vaisampāyana of Yajush; and Jaimini of the Shāma Veda. And Sumantu, who was acquainted with the Atharva-Veda, was also the disciple of the learned Vyāsa. He also took Suta, who was named Lomaharshana, as his disciple in history and Purānas.
