Translation:
Sukadeva Gosvami said: Thus praised by the Nagapatnis, the Supreme Personality of Godhead released the serpent Kaliya, who had fallen unconscious, his heads battered by the striking of the Lord’s lotus feet.
Purport:
According to Srila Visvanatha Cakravarti Thakura, Lord Krsna, upon reaching His decision, immediately jumped down from Kaliya’s hoods and stood before the serpent and his wives. We should remember that when Lord Krsna executed these pastimes, He was just a young village boy in Vrndavana.
