One in the (observance of Sannyasa) should not be unwilling in satisfying the duties included in Yama and those also that walk behind them. Such a person should live energetically according to the ordinances laid down his own mode, and leave off Vedic study and the sacred thread which marks his birth. Given to righteousness and having his senses under complete control, such a person endued with knowledge of self, attains forsooth, to the end for which he tries.
