Mbh 3.206.3d

The learned man, however, even if he be destitute of beauty, displayeth his lustre by refraining from speaking ill of others and well of himself. No example, however, can be met with, in this world, of a person shining brilliantly on account of attributes to be found in him in their reputed measure. If one repenteth of a wrong done by him, that repentance washeth off his sin. The resolution of never doing it again saveth him from future sin, even as, O thou best of Brahmanas, he may save himself from sin by any of those expiations obtained in the scriptures. Even this, O regenerate one, is the sruti that may be seen in respect of virtue. He that having before been virtuous, committeth a sin, or committeth it unknowingly may destroy that sin. For virtue, O Brahmana, driveth off the sin that men commit from ignorance. A man, after having committed a sin, should cease to regard himself any longer as a man. No man can conceal his sins. The gods behold what one does, also the Being that is within every one. He that with piety and without detraction hideth the faults of the honest and the wise like holes in his own attire, surely seeketh his salvation. If a man seeketh redemption after having committed a sin, without doubt he is purged of all his sins and looketh pure and resplendent like the moon emerged from the clouds. A man that seeketh redemption is washed of all his sins, even as the sun, upon rising, dispelleth all darkness. O best of Brahmanas, it is temptation that constitutes the basis of sin. Men that are ignorant commit sin, yielding to temptation alone. Sinful men generally cover themselves with a virtuous exterior, like wells whose mouths are covered by long grass. Outwardly they seem to possess self-control and holiness and indulge in preaching virtuous texts which, in their mouth are of little meaning. Indeed, everything may be noticed in them except conduct that is truly virtuous!’
