Listen, O seeker, to the wise guidance given for the twice-born, those who uphold sacred duties. It is taught that, except for the region lying between the two oceans—the sacred land of Bharat—a twice-born should not reside elsewhere. Within this land, renowned for its holy rivers, a twice-born may dwell, for here sanctity and dharma flourish. One must not live elsewhere in a sacred place, nor settle near a village of outcastes. It is advised not to associate with the ignorant, the arrogant, outcastes, or those who dwell among them. Four acts—officiating at sacrifices, teaching, sexual union, and eating together—are warned against when performed with those of different castes, for they lead to eleven faults known as the mixing of castes. Thus, one should avoid such mingling with every possible effort. Where boundaries are marked with ashes, there is no mixing among castes. Even in a row, division may be made in six ways: by a door, a pillar, or a pathway, ensuring separation. During periods of impurity, one should not converse, nor touch anyone at vital spots. A learned person should never reveal the moon to another, for such acts are discouraged. A fundamental principle is upheld: one should not do to others what is disagreeable to oneself. A foremost twice-born should not speak to one who has not performed the water-offering, nor to one who is impure. Diligently, one must avoid reviling the Veda or the gods, for no expiation is found in the scriptures for such offenses. The punishment is severe: a man is cooked in Raurava hell for a full hundred crore aeons. Therefore, one should cover one's ears and depart, not even looking upon such blasphemies. Quarrels with one’s own people are to be avoided, for engaging in disputes makes one equally at fault and incurs double blame through falsehood. Those who falsely accuse others are called killers of their own sons and cattle, and elders declare that there is no expiation for false accusation. One should not point out that which is hidden by clothing or not visible within. A wise person who is impure should not gaze at the sun, moon, or planets. One should not speak to another while defiled by food or with the mouth covered, nor to one whose limbs are unbound, or who is mad or intoxicated, nor to a woman who is sneezing, yawning, or sitting as she pleases. It is forbidden to step over urine or stand upon it. One should not offer food that is defiled, nor honey, ghee, or sacrificial oblations placed on black antelope skin. Anger, hatred, and attachment should be avoided, as should envy, pride, grief, and delusion. One must not associate with the lowly or those of harsh intellect, nor disrespect the distinguished, and a wise person should never curse oneself. In places where rivers flow or mountains rise, one should not call them 'river' or 'mountain' among their kind, showing reverence for their sacredness. One should not enter water naked, nor cross fire on foot. Never should one go with someone impure to places where hair or private parts are exposed. Nor should one indulge in talk or actions concerning sexual organs, the belly, or frivolity, nor listen to such things. Striking water with feet or hands is forbidden. One should not learn the language of barbarians, nor drag a seat with the feet. Massage may be performed, but only with purpose and not suddenly. Dancing, singing, and playing musical instruments are to be avoided by the wise. Thus, these teachings guide the twice-born in conduct, preserving purity, restraint, and reverence in all actions.
