Many foremost of heroes, approaching the brave Vasudeva and Arjuna as also Shalya and Karna, began each to blow his conch. The battle then commenced (between the two warriors), overwhelming all timid persons with fear. Fiercely they challenged each other like Sakra and Samvara. The standards of the two heroes, perfectly bright, looked exceedingly beautiful on their cars, like the planets Rahu and Ketu risen in the firmament at the time of the universal dissolution. The elephant's rope on Karna's banner, looking like a snake of virulent poison and made of jewels and gems and exceedingly strong and resembling the bow of Indra, looked resplendent (as it waved in the air). That foremost of apes, again, belonging to Partha, with jaws wide open and terrible, and difficult of being gazed at, like the sun himself, inspired fear by his formidable teeth. The impetuous Ape on the standard of the wielder of Gandiva, becoming desirous of battle, rushed from his station and fell upon Karna's standard. Endued with great impetuosity, the Ape, darting forward, struck the elephant's rope with his nails and teeth, like Garuda falling upon a snake. Decked with rows of little bells, hard as iron, and resembling the fatal noose (in the hands of Yama or Varuna), the elephant's rope, filled with wrath, closed with the Ape. Thus in that fierce single combat between those two heroes, which was the result of what had been settled at the time of the match at dice, their standards first battled with each other. Meanwhile the steeds of the one neighed at the steeds of the other. The lotus-eyed Keshava pierced Shalya with his keen glances. The latter also cast similar glances at the former. Vasudeva, however, vanquished Shalya with those glances of his, while Dhananjaya, the son of Kunti, vanquished Karna with his glances. Then the Suta's son, smilingly addressing Shalya, said, "If Partha by any means slays me in battle today, tell me truly, O friend, what thou wilt do after that."
