That woman who abandoning a husband of a superior caste, has congress with a vile person (of a lower order), should be caused by the king to be devoured by dogs in a public place in the midst of a large concourse of spectators.[478] A wise king should cause the male person committing adultery under such circumstances to be placed upon a heated bed of iron and then, placing faggots underneath, burn the sinner thereon. The same punishment, O king, is provided for the woman that is guilty of adultery. The wicked sinner who does not perform expiation within a year of the commission of the sin incurs demerit that is double of what attaches to the original sin. One who associates with such a person for two years must wander over the earth, devoting himself to penances and living upon eleemosynary charity. One associating with a sinner for four years should adopt such a mode of life for five years. If a younger brother weds before his elder brother, then the younger brother, the elder brother and the woman that is married, all three, in consequence of such wedding, become fallen. All of them should observe the vows prescribed for a person who has neglected his sacrificial fire, or practise the vow of Chandrayana for a month, or some other painful vow, for cleansing themselves of their sin. The younger brother, wedding, should give his wife unto his unmarried elder brother. Afterwards, having obtained the permission of the elder brother, the younger brother may take back his wife. By such means may all three be cleansed of their sin. By slaying animals save a cow, the slayer is not stained. The learned know that man has dominion over all the lower animals. A sinner, holding in his hand a yak-tail and an earthen pot, should go about, proclaiming his sin. He should every day beg of only seven families, and live upon what may be thus obtained. By doing this for twelve days he may be cleansed of his sin.
