We have heard that Indra is the foremost (among the celestial) and the king of the Devas. He is endued with immeasurable might, energy, Prowess and glory. Gratifying him by my asceticism, I shall obtain a greatly powerful son. The son that he will give me will be superior to all. He will be capable of defeating the inhabitants of earth and those who are not of this earth. I shall, therefore practice severest asceticism with heart, deed and speech."
