Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
You have prayed to Me and properly worshiped Me by performing the great payo-vrata ceremony for the sake of protecting your sons. Because of Kasyapa Muni’s austerities, I shall agree to become your son and thus protect your other sons.
