Akrūra and Kṛtavarmā were prominent members in the conspiracy to kill Satrājit, having incited Śatadhanvā to kill him. So when they heard of the death of Śatadhanvā at Kṛṣṇa’s hand, and when they also heard that Kṛṣṇa had returned to Dvārakā, they both immediately left the city. The citizens of Dvārakā felt themselves threatened with pestilence and natural disturbances due to the absence of Akrūra from the city. This was a kind of superstition, because while Lord Kṛṣṇa was present there could not be any pestilence, famine or natural disturbances. But in the absence of Akrūra there were apparently some disturbances in Dvārakā. The superstition arose for the following reason: Once in the province of Kāśī (Vārāṇasī) there was severe drought—practically no rain fell. At that time the King of Kāśī arranged the marriage of his daughter, known as Gāndinī, with Śvaphalka, the father of Akrūra. This was done by the King of Kāśī on the advice of an astrologer, and actually it so happened that after the marriage of the King’s daughter with Śvaphalka there was sufficient rainfall in the province. Due to this supernatural power of Śvaphalka, his son Akrūra was considered equally powerful, and people were under the impression that wherever Akrūra or his father stayed there would be no natural disturbances, such as famine or drought. That kingdom is considered happy where there is no famine, pestilence or excessive heat and cold and where people are happy mentally, spiritually and physically. As soon as there was some disturbance in Dvārakā, people considered the cause to be the absence of an auspicious personality in the city. Thus there was a rumor that because of the absence of Akrūra inauspicious things were happening. After the departure of Akrūra, some of the elderly residents of the city also began to perceive inauspicious signs due to the absence of the Syamantaka jewel. When Lord Śrī Kṛṣṇa heard these rumors spread by the people, He decided to summon Akrūra from the kingdom of Kāśī.
Akrūra was Kṛṣṇa’s uncle; therefore, when he came back to Dvārakā, Lord Kṛṣṇa first of all gave him a welcome befitting a superior person. Kṛṣṇa is the Supersoul in everyone and knows everything going on in everyone’s heart. He knew everything that had happened in connection with Akrūra’s conspiracy with Śatadhanvā. Therefore, He smilingly began to speak to Akrūra. Addressing him as the chief among munificent men, Kṛṣṇa said, “My dear uncle, it is already known to Me that the Syamantaka jewel was left by Śatadhanvā with you. Presently there is no direct claimant of the Syamantaka jewel, for King Satrājit has no male issue. His daughter Satyabhāmā is not very eager for this jewel,yet her expected son, as the grandson of Satrājit, would, after performing the regulative principles of inheritance, be the legal claimant of the jewel.” Lord Kṛṣṇa indicated by this statement that Satyabhāmā was already pregnant and that her son would be the real claimant of the jewel and would certainly take the jewel from Akrūra.
Kṛṣṇa continued: “This jewel is so powerful that no ordinary man is able to keep it. I know that you are very pious in activities, so there is no objection to the jewel’s being kept with you. There is one difficulty, and that is that My elder brother, Śrī Balarāma, does not believe My version that the jewel is with you. I therefore request you, O large-hearted one, to show Me the jewel just once before My other relatives so that they may be pacified and reject various kinds of rumors. You cannot deny that the jewel is with you because we can understand that you have enhanced your opulence and are performing sacrifices on an altar made of solid gold.” The properties of the jewel were known: wherever the jewel remained, it would produce for the keeper more than two mounds of pure gold daily. Akrūra was getting gold in that proportion and distributing it profusely at sacrificial performances. Lord Kṛṣṇa cited Akrūra’s lavishly spending gold as positive evidence of his possessing the Syamantaka jewel.
When Lord Kṛṣṇa, in friendly terms and sweet language, impressed Akrūra about the real fact and Akrūra understood that nothing could be concealed from the knowledge of Śrī Kṛṣṇa, he brought out the valuable jewel, covered by cloth but shining like the sun, and presented it before Kṛṣṇa. Lord Kṛṣṇa took the Syamantaka jewel in His hand and showed it to all His relatives and friends present and then returned the jewel to Akrūra in their presence, so that they would know that the jewel was actually being kept by Akrūra in Dvārakā City.
This story of the Syamantaka jewel is very significant. In Śrīmad-Bhāgavatam it is said that anyone who hears the story of the Syamantaka jewel or describes it or simply remembers it will be free from all kinds of defamation and the reactions of all impious activities and thus will attain the highest perfectional condition of peace.
