Hiraṇyakaśipu wanted to become immortal. He wanted not to be conquered by anyone, not to be attacked by old age and disease, and not to be harassed by any opponent. Thus he wanted to become the absolute ruler of the entire universe. With this desire, he entered the valley of Mandara Mountain and began practicing a severe type of austerity and meditation. Seeing Hiraṇyakaśipu engaged in this austerity, the demigods returned to their respective homes, but while Hiraṇyakaśipu was thus engaged, a kind of fire began blazing from his head, disturbing the entire universe and its inhabitants, including the birds, beasts and demigods. When all the higher and lower planets became too hot to live on, the demigods, being disturbed, left their abodes in the higher planets and went to see Lord Brahmā, praying to him that he curtail this unnecessary heat. The demigods disclosed to Lord Brahmā Hiraṇyakaśipu’s ambition to become immortal, overcoming his short duration of life, and to be the master of all the planetary systems, even Dhruvaloka.
