"Yudhishthira said, 'After doing what acts does a man become liable to perform expiation? And what are those acts which he must do for being freed from sin? Tell me this, O grandsire.'
"Vyasa said, 'Having omitted to do those acts that have been ordained, and done those that have been interdicted, and having behaved deceitfully, a man becomes liable to perform expiation. The person in the observance of the Brahmacharya vow, who rises from bed after the sun has risen or goes to bed while the sun is setting, one who has a rotten nail or black teeth, one whose younger brother weds first, one who weds before his elder brother is wedded, one who has been guilty of the slaughter of a Brahmana, one who speaks ill of others, one who weds a younger sister before the elder sister has been wedded, one who weds an elder sister after having wedded a younger one, one who falls away from a vow, one who slays any one of the regenerate classes, one who imparts a knowledge of the Vedas to a person unworthy of it, one who does not impart a knowledge thereof to a person that is worthy of it, one who takes many lives, one who sells flesh, one who has abandoned his (sacred) fire, one who sells a knowledge of the Vedas,111 one who slays his preceptor or a woman, one born in a sinful family, one who slays an animal wilfully,112 one who sets fire to a dwelling house, one who lives by deceit, one who acts in opposition to his preceptor, and one who has violated a compact,--these all are guilty of sins requiring expiation. I shall now mention other acts that men should not do, viz., acts that are interdicted by both the world and the Vedas. Listen to me with concentrated attention. The rejection of one's own creed, the practice of other people's creed, assisting at the sacrifice or the religious rites of one that is not worthy of such assistance, eating of food that is forbidden, deserting one that craves protection, neglect in maintaining servants and dependants, selling salt and treacle (and similar other substances), killing of birds and animals, refusal, though competent, to procreate upon a soliciting woman, omission to present the daily gifts (of handfuls of grass to kine and the like), omission to present the dakshina, humiliating a Brahmana,--these all have been pronounced by persons conversant with duty to be acts that no one should do. The son that quarrels with the father, the person that violates the bed of his preceptor, one that neglects to produce offspring in one's wedded wife, are all sinful, O tiger among men! I have now declared to thee, in brief as also in detail, those acts and omissions by which a man becomes liable to perform expiation.
