“Shishupala's soul's merging into the transcendental body of Krishna reminds us of the story of Jaya and Vijaya, who fell to the material world from the Vaikuntha planets upon being cursed by the four Kumaras. For their return to the Vaikuntha world, it was arranged that both Jaya and Vijaya, for three consecutive births would act as deadly enemies of the Lord, and at the end of these lives they would again return to the Vaikuntha world and serve the Lord as His associates.” (Krishna, The Supreme Personality of Godhead, Vol 2, Ch 19)
