Vasudeva said To that disciple who had humbly sought his instruction and put the questions duly. Who was devoted to his preceptor and endued with tranquillity, and who always acted in a manner that was agreeable (to his instructor), who lived so constantly by the side of his instructor as to have almost become his shadow, who was selfcontrolled and who had the life of a Yati and a Brahmacharin, O son of Pritha, that preceptor gifted with intelligence and observant of vows, duly explained all the questions, O foremost of Kuru's race, O chastiser of all enemies.
