Satrajit, one of Lord Krishna's kinsmen, was once blessed by the Sun god with a beautiful gem called Šyamantaka, which had the special quality of yielding a bag of gold to its owner every day. One day, Krishna suggested to Satrajit that it would be a good idea if he left the gem with Ugrasena, the king of the land, so that the entire country would benefit by the grace of the Sun. Due to his extreme arrogance, however, Satrajit laughed at Krishna's suggestion and refused to part with the gem. 

One day soon thereafter, Satrajit permitted his brother Prasenajit to wear the jewel for a day and go to the forest hunting. When Prasenajit failed to return home that night, Satrajit became extremely worried. Early next morning, Satrajit proceeded to the forest with a search team and was horrified to find the dead bodies of Prasenajit and his horse in the midst of the dense forest. Sure enough the jewel was not found on Prasenajit.

Sad and angry at the death of his brother, Satrajit recalled his earlier conversation with Krishna and surmised that Krishna was the one who killed his brother in order to get the jewel. Although Krishna was amused to hear Satrajit's accusation, He realized that in order to clear the air and vindicate His honor, the truth must be found and presented to the community. Accordingly, He and His friends went to the forest to ascertain the truth.

Noticing the footprints of a lion leading away from the spot where Prasenajit's body was found, Krishna and His companions followed the lion's footprints and were soon surprised to find the carcass of a dead lion on their path. They observed signs of a fierce struggle and determined that a bear had a fight with the lion and killed the lion at that spot. Following the tracks made by the bear the group was led to the mouth of an immense cave. As he entered the cave, Krishna was startled to see a bear cub playing with the Syamantaka gem. Noticing Krishna slowly approach the cub to retrieve the gem, the mother bear let out a frightening cry. Hearing the noise, a great bear as old as time came rushing out and began to attack Krishna. The old bear was none other than Jãmbavãn who played a great part during the war Šri Rãma fought with Rãvana in the Treta Yuga. 

Krishna and Jãmbavãn fiercely fought uninterruptedly for four weeks at the end of which the weary Jãmbavãn exclaimed to Krishna that the only other person who was as skillful and powerful as Krishna; was Šri Rãma. With the intention of provoking Jãmbavãn, Krishna belittled Šri Rãma, at which Jãmbavãn renewed his attack on Krishna. Suddenly Krishna assumed the form of Šri Rãma and the startled Jãmbavãn immediately fell at the feet of his beloved Master. Šri Rãma lovingly lifted up Jãmbavãn and explained to him that Krishna was none other than Himself and related His urgent need to have the gem. The happy Jãmbavãn gave Him the jewel along with his daughter Jãmbavati. 

The victorious Krishna and His companions returned to Dwãraka and related to all the truth about the killing of Prasenajit and the subsequent happenings. He then took the disputed jewel and placed it around Satrajit's neck. Satrajit was ashamed of his conduct and wished to make amends by giving his daughter Satyabhãma in marriage to Krishna.
