Mbh 12.292.1b

Through sin the very vision of the sinner becomes perverse, and he confounds his body and its unstable accompaniments with the Soul.[1510] That foolish man who does not succeed in betaking himself to Renunciation in this world becomes afflicted with great grief when he departs to the next world.[1511] An uncoloured cloth, when dirty, can be cleaned, but not a piece of cloth that is dyed with black; even so, O king, listen to me with care, is it the case with sin. That man who, having knowingly committed sin, acts righteously for expiating that sin, has to enjoy and endure the fruits of his good and bad acts separately.[1512] The utterers of Brahma maintain, under the authority of what has been laid down in the Vedas, that all acts of injury committed in ignorance are cancelled by acts of righteousness. A sin, however, that is committed consciously is never cancelled by righteousness. Thus say the regenerate utterers of Brahma who are conversant with the scriptures of Brahmana. As regards myself, my view is that whatever acts are done, be they righteous or sinful, be they done knowingly or otherwise, remain (and are never destroyed unless their fruits are enjoyed or endured).[1513] Whatever acts are done by the mind with full deliberation, produce, according to their grossness or subtility, fruits that are gross or subtile.[1514] Those acts, however, O thou of righteous soul, which are fraught with great injury, if done in ignorance, do without fail produce consequences and even consequences that lead to hell, with this difference that those consequences are disproportionate in point of gravity to the acts that produce them.[1515] As to those acts (of a doubtful or unrighteous nature) that may be done by the deities or ascetics of reputation, a righteous man should never do their like or, informed of them, should never censure them.
