Many great Rishis, O son, who had the power to see immediately the fruits of their ascetic merit, those numberless ascetics who pass by the appellation of Yayavaras, many Rishis of very austere penances and endued with accurate knowledge about distinctions of duty, and many other Brahınanas too numerous to mention, adopted the forest mode of life. The Vaikhanasas, the Valikhilyas, the Saikatas, all of whom were given to austere penances, who were firm in virtue, who had controlled their senses, and who used to see the fruits of their penances immediately, adopted this mode of life and finally went to heaven.
