Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
This demon, Hiranyakasipu, received from me the benediction that he would not be killed by any living being within my creation. With this assurance and with strength derived from austerities and mystic power, he became excessively proud and transgressed all the Vedic injunctions.
