Mbh 3.135.3

“Lomasa said, ‘Bharadwaja and Raivya were two friends. And they dwelt here, ever taking the greatest pleasure in each other’s company. Now, Raivya had two sons, named Arvavasu and Paravasu. And, Bharadwaja, O Bharata’s son, had an only son, named Yavakri. Raivya and his two sons were versed in the Vedas, while Bharadwaja practised asceticism. But, O son of Bharata, from their boyhood, the friendship subsisting between those two was unequalled. O sinless one, the highspirited Yavakri finding that his father, who practised asceticism, was slighted by the Brahmanas, while Raivya with his sons was greatly respected by them, was overwhelmed with sorrow, and became sore aggrieved. Thereupon, O son of Pandu, he entered upon severe austerities, for (obtaining) a knowledge of the Vedas. And he exposed his body to a flaming fire. By thus practising the most rigid austerities, he caused anxiety in the mind of Indra. Then Indra, O Yudhishthira, went to him and addressed him saying, ‘Wherefore, O sage, hast thou become engaged in practising such rigid austerities?’ Yavakri said, ‘O thou adored of celestial hosts, I am practising severe penances, because I wish that such a knowledge of the Vedas as hath never been acquired by any Brahmana whatever, may be manifest unto me. O conqueror of Paka, these endeavours of mine have been for Vedic lore. O Kausika, by the force of my asceticism. I purpose to obtain all sorts of knowledge. O lord, a knowledge of the Vedas as learnt through teachers, is acquired in a long time. Therefore, (with the view of attaining in short time a proficiency in the Vedas), I have put forth these high endeavours.’ Indra said, ‘O Brahmana sage, the way that thou hast adopted is not the proper way. What for, O Brahamana, wilt thou destroy thyself? Go and learn from the lips of a preceptor.’
