He himself became the lord of riches and Yama; and that Asura appropriated to himself, without reserve, all that was offered in sacrifice to the celestials. O foremost of ascetics, renouncing their own region the celestials, through his fear, wandered upon the earth, disguised in mortal shapes. Having conquered the three worlds, he was inflated with the pride of the riches, and being eulogised by the Gandharvas, enjoyed all wished-for objects.
In plain words: Hiranyakashipu also made himself lord of wealth and of death. He took all the offerings meant for the gods. The frightened gods fled their heaven and hid on earth disguised as humans. Proud and rich, the demon king enjoyed every pleasure he wanted while singers praised him.
