Mbh 3.166.2a

“Arjuna said, ‘O mighty monarch, listen how I duly beheld him of a hundred sacrifice and the divine Sankara also. O grinder of foes, O king, having acquired that science which thou hadst directed me (to learn), I at thy command went to the forest, for practising penances. From Kamyaka repairing to the Bhrigutunga, I spent there one night, being engaged in austerities And it came to pass that on the next I saw a certain Brahmana. And he asked me, saying, ‘O son of Kunti, whither wilt thou go?’ Thereupon, O descendant of the Kurus, I truly related unto him everything. And, O best of kings, having heard the true account, the Brahmana became well-pleased with me, and, O king, praised me. Then the Brahmana, pleased with me, said, ‘O Bharata, be thou engaged in austerities. By performing penances, thou wilt in a short time behold the lord of the celestials.’ And according to his advice I ascended the Himavan, and, O mighty king, began to practise penances, (the first) month subsisting on fruit and roots. I spent the second month, subsisting on water. And, O Pandava, in the third month I totally abstained from food. And in the fourth month I remained with upraised arms. And a wonder it is that I did not lose any strength. And it came to pass that when the first day of the fifth month had been spent, there appeared before me a being wearing the form of a boar, turning up the earth with his mouth, stamping the ground with his feet, rubbing the earth with his breast, and momentarily going about in a frightful manner. And him followed a great being in the guise of a hunter furnished with the bow, arrows, and the sword, and surrounded by females. Thereupon, taking my bow and the two inexhaustible quivers, I pierced with shafts that terrible and frightful creature. And simultaneously (with me) that hunter also drawing a strong bow, more severely struck at (the animal), as if shaking my mind.
