And like animal, the powerful one Nahusha carried them on the back of Rishis. Beating the very dwellers of heaven with his beauty, his asceticism, his prowess and energy, he ruled the earth, as if he was Indra himself. Nahusha begot six sweet-speeched sons, namely, Yati, Yayati, Sanyati, Aayati, Ayati and Dhruva. Yati adopted asceticism and became a great Rishi like Brahma himself.
