Mbh 13.142.4a

"'"'Mahadeva said, "O goddess, the shaving of the head and the wearing of the brown robes are the indications of those recluses that rove about in freedom; while the indications of those that sport with wedded wives consist in passing their nights at home. Performing ablutions three times a day is the duty of the classes, while the Homa, with water and fruits from the wilderness, belongs to the wedded recluses as performed by the Rishis in general. Absorption, Yoga-meditation, and adherence to those duties that constitute piety and that have been laid down as such (in the scriptures and the Vedas) are some of the other duties prescribed for them. All those duties also of which I have spoken to thee before as appertaining to recluses residing in forests, are the duties of these also. Indeed, if those duties are observed, they that observe them, attain to the rewards that attach to severe penances. Those forest recluses that lead wedded lives should confine the gratification of their senses to these wedded wives of theirs. By indulging in sexual congress with their wives at only those times when their seasons come, they conform to the duties that have been laid down for them. The religion which these virtuous men are to follow is the religion that has been laid down and followed by the Rishis. With their eyes set upon the acquisition of righteousness, they should never pursue any other object of desire from a sense of unrestrained caprice. That man who makes the gift unto all creatures of an assurance of perfect harmlessness or innocence, freed as his soul becomes from the stain of malice or harmfulness, becomes endued with righteousness. Verily, that person who shows compassion to all creatures, who adopts as a vow a behaviour of perfect sincerity towards all creatures, and who constitutes himself the soul of all creatures, becomes endued with righteousness.
