When these calamities reached the ears of Krishna he gathered some members of the Yadu family and in their company followed the course of Prasena by the impressions of his horse's hoofs. And having found it by this way that he and his horse had been destroyed by the lion he was acquitted by all people of any share in the death. Desirous of getting back the jewel, he thence followed the foot-marks of the lion and at no great distance came to the place where the lion had been killed by the bear. Pursuing the foot-prints of the latter he arrived at the foot of a mountain where having kept the Yādavas he pursued the course. And following the impressions of the feet he found out a cavern and before he entered it he heard the nurse of Sukumāra saying to him "The lion killed Prasena; the lion has been killed by Jamvabat: weep not Sukumāra the Syamantaka is your own". Having thus ascertained the truth Krishna entered into the cavern and espied the jewel in the hands of the nurse who was giving it as a plaything to Sukumāra. The nurse in no time found out his approach and seeing his eyes eagerly fixed upon the jewel called aloud for help. Hearing her cries, Jamvabat, worked up with anger, came to that place and an encounter took place between him and the Achyuta which continued for twenty, one days. The Yādavas who followed Krishna waited there for seven or eight days expecting his return but as the slayer of Madhu did not come they arrived at the conclusion that he must have been destroyed in the cave. "It could not have taken so many days" they thought "to defeat a foe". They therefore went away, and came back to Dwārakā and announced that Krishna had been killed.
