On the battlefield, hundreds of rivers of blood flowed from the limbs of the humans, elephants and horses who had been cut to pieces. In these rivers arms resembled snakes; human heads, turtles; dead elephants, islands; and dead horses, crocodiles. Hands and thighs appeared like fish, human hair like waterweeds, bows like waves, and various weapons like clumps of bushes. The rivers of blood teemed with all of these.
Chariot wheels looked like terrifying whirlpools, and precious gems and ornaments resembled stones and gravel in the rushing red rivers, which aroused fear in the timid, joy in the wise. With the blows of His plow weapon the immeasurably powerful Lord Balarāma destroyed Magadhendra’s military force. And though this force was as unfathomable and fearsome as an impassable ocean, for the two sons of Vasudeva, the Lords of the universe, the battle was hardly more than play.
