Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Hiranyakasipu thought: I have used many ill names in chastising this boy Prahlada and have devised many means of killing him, but despite all my endeavors, he could not be killed. Indeed, he saved himself by his own powers, without being affected in the least by these treacheries and abominable actions.
