By Swami Harshananda
Satrājita was a Yādava chieftain. Through severe austerities he had appeased Surya. Pleased with him, Surya had given him a special gem called Syamantakamaṇi which would yield 160 tolas of gold every day. Satrājit had strung it into a necklace which could be worn whenever one liked.
Once Kṛṣna is said to have requested Satrājit to give it to him but Satrājit refused. One day, Prasena, brother of Satrājit, wearing this necklace, went out hunting. A lion killed him and was taking the necklace away when Jāmbavān encountered it, killed it and took the necklace to give it to Jāmbavatī, his daughter. She tied it to the cradle of the baby in her house.
When Satrājit heard that Prasena had been killed and that the necklace had been missing he suspected Kṛṣṇa of stealing it. Kṛṣṇa quickly searched for it, recovered it from Jambavan and restored it to Satrājit.
