Mbh 8.77.1d

Blood constituted its water, and cars its eddies; and elephants were the alligators with which it teemed. Men were its fishes, and steeds its sharks, and the hair of animals formed its woods and moss. Arms lopped off from trunks formed its foremost of snakes. Innumerable jewels and gems were carried along by the current. Thighs constituted its gravels, and marrow its mire. And it was covered with heads forming its rocks. And bows and arrows constituted the rafts by which men sought to cross that terrible river, and maces and spiked bludgeons formed its snakes. And umbrellas and standards formed its swans, and head-gears its foam. Necklaces constituted its lotuses, and the earthy dust that arose formed its waves. Those endued with noble qualities could cross it with ease, while those that were timid and affrighted found it exceedingly difficult to cross. Warriors constituting its crocodiles and alligators, it ran towards the region of Yama. Very soon, indeed, did that tiger among men cause that river to flow. Even as the terrible Vaitarani is difficult of being crossed by persons of unrefined souls, that bloody river, terrible and enhancing the fears of the timid, was difficult to cross. Thither where that best of car-warriors, the son of Pandu, penetrated, thither he felled hostile warriors in hundreds and thousands. Seeing those feats achieved in battle by Bhimasena, Duryodhana, O monarch, addressing Shakuni, said, "Vanquish, O uncle, the mighty Bhimasena in battle. Upon his defeat the mighty host of the Pandavas may be regarded as defeated." Thus addressed, O monarch, the valiant son of Subala, competent to wage dreadful battle, proceeded, surrounded by his brothers. Approaching in that battle Bhima of terrible prowess, the heroic Shakuni checked him like the continent resisting the ocean. Though resisted with keen shafts, Bhima, disregarding them all, proceeded against the sons of Subala.
