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.
Not recognizing his master, Jāmbavān challenged Him to fight. There was then a great fight between Kṛṣṇa and Jāmbavān, in which they fought like two opposing vultures. Whenever there is an eatable corpse the vultures fight heartily over the prey. Kṛṣṇa and Jāmbavān first of all fought with weapons, then with stones, then with big trees, then hand to hand, until at last they were hitting each other with their fists, their blows like the striking of thunderbolts. Each expected victory over the other, but the fighting continued for twenty-eight days, both in daytime and at night, without stopping.
Although Jāmbavān was the strongest living entity of that time, practically all the joints of his bodily limbs became slackened and his strength was reduced practically to nil, for he was struck constantly by the fists of Śrī Kṛṣṇa. Feeling very tired, with perspiration all over his body, Jāmbavān was astonished. Who was this opponent who was fighting so hard with him? Jāmbavān was quite aware of his own superhuman bodily strength, but when he felt tired from being struck by Kṛṣṇa, he could understand that Kṛṣṇa was no one else but his worshipable Lord, the Supreme Personality of Godhead. This incident has special significance for devotees. In the beginning, Jāmbavān could not understand Kṛṣṇa because his vision was obscured by material attachment. He was attached to his boy and to the greatly valuable Syamantaka jewel, which he did not want to spare for Kṛṣṇa. In fact, when Kṛṣṇa came there he was angry, thinking that Kṛṣṇa had come to take away the jewel. This is the material position: although one is very strong in body, that cannot help him understand Kṛṣṇa.
