yatkiṃcidduṣkṛtaṃ tasya sarvaṃ naśyati dehinaḥ
pañca saptāṣṭa daśa vā dvādaśāho'pi viṃśatiḥ
mlecchairnītasya viprasya pañcagavyaṃ viśodhanam

whatever misdeed belongs to that embodied being, all of it perishes. / For a Brahmin carried away by Mlecchas for five, seven, eight, ten, twelve days, or twenty, / the five products of the cow are the purification.
