By these expiations twice-born men must be purified whose sins are known, but let him purify those whose sins are not known by (the recitation of) sacred texts and by (the performance of) burnt oblations.
ख्यापनेनानुतापेन तपसाऽध्ययनेन च । पापकृत्मुच्यते पापात् तथा दानेन चापदि ॥ २२७ ॥
By confession, by repentance, by austerity, and by reciting (the Veda) a sinner is freed from guilt, and in case no other course is possible, by liberality.
He who has committed a sin and has repented, is freed from that sin, but he is purified only by (the resolution of) ceasing (to sin and thinking) ’I will do so no more.’
