"And thus on account of wealth those two fools, Supritika and Vibhavasu, from each other's curse, have become an elephant and a tortoise respectively. Owing to their wrath, they have both become inferior animals. And they are engaged in hostilities with each other, proud of their excessive strength and the weight of their bodies. And in this lake those two beings of huge bodies are engaged in acts according to their former hostility. Look here, one amongst them, the handsome elephant of huge body, is even now approaching. Hearing his roar, the tortoise also of huge body, living within the waters, cometh out, agitating the lake violently. And seeing him the elephant, curling his trunk, rusheth into the water. And endued with great energy, with motion of his tusks and fore-part of his trunk and tail and feet, he agitates the water of the lake abounding with fishes. And the tortoise also of great strength, with upraised head, cometh forward for an encounter. And the elephant is six yojanas in height and twice that measure in circumference. And the height of the tortoise also is three yojanas and his circumference ten. Eat thou up both of them that are madly engaged in the encounter and bent upon slaying each other, and then accomplish the task that thou desirest. Eating that fierce elephant which looketh like a huge mountain and resembleth a mass of dark clouds, bring thou amrita.'
