But we know, as we have often said, that then only have we made satisfaction for past sins, when the very motions and feelings, through which we were guilty of what we have to sorrow for, have been eradicated from our hearts. But no one should fancy that he can secure this, unless he has first with all the fervour of his spirit cut off the opportunities and occasions, owing to which he fell into those sins; as for instance, if through dangerous familiarity with a woman he has fallen into fornication or adultery, he must take the utmost pains to avoid even looking on one; or if he has been overcome by too much wine and over-eating, he should chastise with the utmost severity his craving for immoderate food. And again if he has been led astray by the desire for and love of money, and has fallen into perjury or theft or murder or blasphemy, he should cut off the occasion for avarice, which has allured and deceived him. If he is driven by the passion of pride into the sin of anger, he should with all the virtue of humility, remove the incentive to arrogance. And so, in order that each single sin may be destroyed, the occasion and opportunity by which or for which it was committed should be first got rid of. For by this curative treatment we can certainly attain to forgetfulness of the sins we have committed.
