jñānapūrvaṃ kṛtaṃ pāpaṃ chādayantyabahuśrutāḥ |
nainaṃ manuṣyāḥ paśyanti paśyanti tridivaukasaḥ || 26 ||

When giving eatables to another (seated at his dish), one should say, 'Is it sufficient?' When presenting drink, one should ask, 'Will it gratify,' and when giving sweetened milk and rice, or sugared gruel of barley, or milk with sesame or pease, one should ask 'Has it fallen?' After shaving, after spitting, after bathing, and after eating, people should worship Brahmanas with reverence, Such worship is sure to bestow longevity on sickly men. One should not pass urine with face turned towards the sun, nor should one see one's own excreta. One should not lie on the same bed with a woman, nor eat with her. In addressing seniors one should never apply the pronoun you to them or take their names. Thouing or the taking of names is not censurable in addressing inferiors or equals in age. The hearts of sinful men betray the sins committed by them. Those sinful men that conceal their conscious sins from good men meet with destruction. Only ignorant fools seek to conceal the sins which they commit consciously. It is true that human beings do not see those sins but the gods see them. A sin concealed by another sin leads to fresh sins. An act of merit, again, if concealed by an act of merit, increases the merit. The acts of a virtuous man always follow in the wake of virtue. A man destitute of understanding never thinks of the sins committed by him. Those sins, however, overtake the doer that has fallen away from the scriptures.
