Translation:
Obsessed with hatred of Lord Krsna throughout three lifetimes, Sisupala attained the Lord’s transcendental nature. Indeed, one’s consciousness determines one’s future birth.
Purport:
Sisupala and his friend Dantavakra, who will be killed by Krsna in Chapter Seventy-eight, were previously Jaya and Vijaya, two gatekeepers in Vaikuntha. Because of an offense, the four Kumaras cursed them to take three births in the material world as demons. The first birth was as Hiranyaksa and Hiranyakasipu, the second as Ravana and Kumbhakarna, and the third as Sisupala and Dantavakra. In each birth they were completely absorbed in enmity toward the Lord and were slain by Him.
Srila Prabhupada explains the position of Sisupala as follows: “Although Sisupala acted as the enemy of Krsna, he was not for a single moment out of Krsna consciousness. He was always absorbed in thought of Krsna, and thus he got the salvation of sayujya-mukti, merging into the existence of the Supreme, and finally became reinstated in his original position of personal service. The Bhagavad-gita corroborates the fact that one who is absorbed in the thought of the Supreme Lord at the time of death immediately enters the kingdom of God after quitting his material body.”
The Third and Seventh cantos of the Srimad-Bhagavatam elaborately describe the incident wherein the Lord’s personal associates were cursed to come to the material world as His enemies. In this connection, Srila Visvanatha Cakravarti quotes the following verse (Bhag. 7.1.47):
vairanubandha-tivrena
dhyanenacyuta-satmatam
nitau punar hareh parsvam
jagmatur visnu-parsadau
“These two associates of Lord Visnu — Jaya and Vijaya — maintained a feeling of enmity for a very long time. Because of always thinking of Krsna in this way, they regained the shelter of the Lord, having returned home, back to Godhead.”
