In the city, when Satrājit's younger brother Prasena did not return from the forest with the jewel, Satrājit became very upset. He did not know that his brother had been killed by a lion and that the lion had been killed by Jāmbavān. He thought instead that because Kṛṣṇa wanted that jewel, which had not been delivered to Him, Kṛṣṇa might have therefore taken the jewel from Prasena by force and killed him. This idea grew into a rumor, which Satrājit spread in every part of Dvārakā.
The false rumor that Kṛṣṇa had killed Prasena and taken away the jewel spread everywhere like wildfire. Kṛṣṇa did not like to be defamed in that way, and therefore He decided that He would go to the forest and find the Syamantaka jewel. Taking with Him some of the important inhabitants of Dvārakā, Kṛṣṇa went to search out Prasena, the brother of Satrājit, and found him dead, killed by the lion. At the same time, Kṛṣṇa also found the lion killed by Jāmbavān, who is generally called Ṛkṣa. It was found that the lion had been killed by the hand of Ṛkṣa without the assistance of any weapon. Kṛṣṇa and the citizens of Dvārakā then found in the forest a great tunnel, said to be the path to Ṛkṣa's house. Kṛṣṇa knew that the inhabitants of Dvārakā would be afraid to enter the tunnel; therefore He asked them to remain outside, and He Himself entered the dark tunnel alone to find Ṛkṣa, Jāmbavān. After entering the tunnel, Kṛṣṇa saw that the valuable jewel known as Syamantaka had been given to the son of Ṛkṣa as a toy. To take the jewel from the child, Kṛṣṇa approached and stood before him. When the nurse taking care of Ṛkṣa's child saw Kṛṣṇa standing before her, she was afraid, thinking He might take away the valuable Syamantaka jewel, and she cried out loudly in fear.
Hearing the nurse's cries, Jāmbavān appeared on the scene in a very angry mood. Jāmbavān was actually a great devotee of Lord Kṛṣṇa, but because he was angry he could not recognize his master and thought Him to be an ordinary man. This brings to mind the statement of the Bhagavad-gītā in which the Lord advises Arjuna to get free from anger, greed and lust in order to rise to the spiritual platform. Lust, anger and greed run parallel in the heart and check one's progress on the spiritual path.
