Mahabharata Anushasna Parva Chapter 142:2

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 142:2 They are always devoted to the three fires. Righteous in their conduct and adhering to the path of virtue, they attain to the highest end. These Munis, crowned with (ascetic) success and ever devoted to the religion of Truth, attain to the highly sacred region of Brahman or the eternal region of Soma. O auspicious goddess, I have thus recited to thee, in brief, the outlines of the religion that is followed by forest recluses and that has many practices in detail." 'Uma said, "O holy one, O lord of all creatures, O thou that art worshipped by all beings, I desire to hear what the religion is of those Munis that are followers of the scriptures treating of ascetic success. Do thou recite it to me. Residing in woods and forests and well-accomplished in the scriptures of success, some amongst them live and act as they like, without being restrained by particular practices; others have wives. How, indeed, have their practices been laid down?" '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. A bath in all the Vedas, and a behaviour of sincerity towards all creatures, are looked upon as equal in point of merit; or, perhaps, the latter is a little distinguished above the other in point of merit. Sincerity, it has been said, is Righteousness; while insincerity or crookedness is the reverse.
