Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami said: My dear King Pariksit, you were burned by the brahmastra of Asvatthama, but when Lord Krsna entered the womb of your mother, you were saved. Similarly, although the one embryo was cut into forty-nine pieces by the thunderbolt of Indra, they were all saved by the mercy of the Supreme Personality of Godhead.
