One day, Prasen rode out hunting, wearing the Gem. Both Prasen and his horse were killed by a lion. Then Jambavant the bear killed the lion and took the Gem.
Thus, the Gem changed several hands. However, back at Dwarka, Shri Krishna’s reputation was marred by a rumor that He had stolen the Gem. It is seen, here, how innocent people are blamed unfairly. When even Shri Krishna faced slander, how can anyone hope to escape it?
The Lord Shri Krishna began to take steps to clear His name. He searched till he reached Jambavan’s cave. A number of highly respected citizens were with Him. Shri Krishna told them to wait outside, and entered the cave alone.
Inside the cave, there was a confrontation between Jambavant and Shri Krishna. They wrestled fiercely for twenty eight days. Ultimately Jambavant recognized that this was the Lord Incarnate, and gave – not only the Gem – but also his daughter, Jambavati, to Shri Krishna.
