SB 7.3.23, Translation and Purport

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.
