Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Wanting to pacify Kamsa, who was so cruel and envious that he was shamelessly ready to kill his sister, the great soul Vasudeva, who was to be the father of Krsna, spoke to him in the following words.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Vasudeva, who was to be the father of Krsna, is described here as maha-bhaga, a very upright and sober personality, because although Kamsa was ready to kill Vasudeva’s wife, Vasudeva remained sober and unagitated. In a peaceful attitude, Vasudeva began to address Kamsa by putting forward reasonable arguments. Vasudeva was a great personality because he knew how to pacify a cruel person and how to forgive even the bitterest enemy. One who is fortunate is never caught, even by tigers or snakes.
