“On the other hand, Kunti’s son, Yudhishthira, (seeing) and reflecting on dreadful ill omens, became alarmed. Terrified by the blaze of the points of the horizon, jackals stationing themselves on the right of that hermitage, set up frightful and inauspicious yells. And ugly Vartikas as of dreadful sight, having one wing, one eye, and one leg, were seen to vomit blood, facing the sun. And the wind began to blow dryly, and violently, attracting grits. And to the right all the beasts and birds began to cry. And in the rear the black crows cried, ‘Go!’ ‘Go!’ And momentarily his (Yudhishthira’s) right arm began to twitch, and his chest and left leg shook (of themselves). And indicating evil his left eye contracted spasmodically. Thereupon, O Bharata, the intelligent Yudhishthira the just, inferring some great calamity (to be imminent), asked Draupadi, saying, ‘Where is Bhima?’ Thereat Panchali said that Vrikodara had long gone out. Hearing this, that mighty-armed king set out with Dhaumya, after having said unto Dhananjaya, “Thou shouldst protect Draupadi.’ And he also directed Nakula and Sahadeva to protect the Brahmanas. And issuing from the hermitage that lord, Kunti’s son, following the footprints of Bhimasena, began to search for him in that mighty forest. And on coming to the east, he found mighty leaders of elephant-herds (slain) and saw the earth marked with Bhima’s (foot-prints). Then seeing thousands of deer and hundreds of lions lying in the forest, the king ascertained his course. And on the way were scattered trees pulled down by the wind caused by the thighs of that hero endued with the speed of the wind as he rushed after the deer.
