Translation: 
As soon as he was sprinkled with the water from Lord Brahmā’s waterpot, Hiraṇyakaśipu arose, endowed with a full body with limbs so strong that they could bear the striking of a thunderbolt. With physical strength and a bodily luster resembling molten gold, he emerged from the anthill a completely young man, just as fire springs from fuel wood.
Purport: 

Hiraṇyakaśipu was revitalized, so much so that his body was quite competent to tolerate the striking of thunderbolts. He was now a young man with a strong body and a very beautiful bodily luster resembling molten gold. This is the rejuvenation that took place because of his severe austerity and penance.
