In the illustrious lineage of the Yadus, the Sumahābhojas and Mārtikāvalas flourished with renown. Among their family, Gāndhārī and Mādrī became the beloved wives of Vṛṣṇi. Gāndhārī bore a son named Sumitra, a joy to his friends, while Mādrī gave birth to Yudhājit and Deva-mīḍhuṣa. From this noble line, Anamitra and his son were both men of excellence. Anamitra’s son was Nighna, and Nighna in turn had two sons: the greatly fortunate Prasena and Śakrajit, who was as dear to him as his own life. One day, at the end of the night, Śakrajit, the foremost among charioteers, set out in his chariot to the riverbank to perform his morning ablutions and greet the rising sun. As he approached, the radiant Sun-god Vivasvān himself appeared before him, his form encircled with dazzling light, indistinct yet awe-inspiring. Śakrajit addressed the Sun: “O lord of lights, just as I see you shining in the sky, so now you stand before me. What difference is there between your celestial form and your presence here, radiant and encircled with brilliance?” Pleased by these words, the venerable Sun removed the Syamantaka gem from around his own neck and bestowed it upon the king. As Śakrajit received the gem, he beheld the Sun in a tangible form, and stood in silent contemplation for a moment. As Vivasvān was about to depart, Śakrajit spoke again: “O radiant one, whose fiery splendor traverses the worlds, at this very moment grant me that gem.” The resplendent Bhāskara gave him the Syamantaka jewel, and Śakrajit, filled with joy, returned to his city. As he entered, the people, astonished by his brilliance, ran after him, exclaiming, “This is the Sun himself entering!” Thus, Śakrajit entered the inner city and his palace, astonishing all who beheld him. With affection, Śakrajit gave the divine Syamantaka gem to his brother Prasena. Wherever the Syamantaka gem resided, the kingdom enjoyed timely rains and freedom from disease. Govinda, Krishna himself, desired the Syamantaka gem from Prasena. Though he was able, he did not seize it, nor did he take it by force or guile. One day, Prasena went hunting, proudly adorned with the gem. But because of the Syamantaka, he met a terrible fate: he was slain by a lion. Soon after, Jāmbavān, king of the bears, killed that lion, took the divine jewel, and carried it into his cave. When the Vṛṣṇis and Andhakas learned of Prasena’s death and the disappearance of the gem, suspicion fell upon Krishna. They thought he coveted the jewel and was responsible for the misfortune. Unable to bear these false accusations, the mighty Krishna, slayer of enemies, set out into the forest to clear his name. There, with his companions, he searched for Prasena, following his tracks through the wilderness. Exhausted from their quest, they came upon the mountain of the bears and the great Vindhya mountain. Though the gem was not to be found, Krishna discovered Prasena’s lifeless body, along with his slain horse. Nearby, he saw the lion that had killed Prasena, itself now dead at the hands of a bear. Following the bear’s tracks, Krishna sought the entrance to its cave. There, he heard a tumultuous cry—a woman in distress. It was Jāmbavān’s nurse, comforting the bear prince, saying, “Do not weep, dear one, for the jewel. The lion killed Prasena, and Jāmbavān killed the lion. This is the Syamantaka jewel—do not cry, gentle child.” Hearing this, Krishna quickly entered the cave and saw Prasena’s body near the entrance. Venturing further, the blessed one came face to face with Jāmbavān, king of the bears, renowned for his wisdom. There, in the darkness of the cave, Krishna and Jāmbavān engaged in a mighty struggle, wrestling with their arms for twenty-one days. Meanwhile, Krishna’s companions, believing him lost, returned to Dvāravatī and spread word that Krishna had fallen. At last, Krishna overcame Jāmbavān. In recognition of Krishna’s divine power, Jāmbavān offered his daughter Jāmbavatī in marriage to him, along with the Syamantaka gem. Thus reconciled, Krishna purified himself and departed from the cave with both the jewel and his new bride. Returning to the city, Krishna presented the Syamantaka gem to Satrājit in the assembly of the Sātvatas, thereby clearing himself of all suspicion. He spoke kindly to Jāmbavatī, and the false accusation against him was dispelled. It is said that whoever knows how Krishna was thus exonerated will never utter a false accusation. Satrājit had a hundred sons by his ten wives, but three were especially renowned: Bhaṅgakāra, the eldest, Vīra, and Vratapati, as well as Supriya, the youngest. Bhaṅgakāra’s daughter, Dvāravatī, gave birth to three sons, all of whom were handsome and virtuous. Among women, Satyabhāmā was the most illustrious, steadfast in her vows like an ascetic. Her father gave her in marriage to Krishna. As for the Syamantaka gem, which Krishna had returned to Satrājit, it was later taken by Bhoja, Śatadhanvan. Thus, the tale of the Syamantaka gem and Krishna’s vindication is remembered among the Yadus.
