Remembrance of wrongs is the consummation of anger, the keeper of sin, hatred of righteousness, ruin of virtues, poison of the soul, worm of the mind, shame of prayer… You will know that you have completely freed yourself of this rot, not when you pray for he person who has offended you, not when you exchange presents with him, not when you invite him to your table, but only when, on hearing that he has fallen into bodily or spiritual misfortune, you suffer and weep for him as for yourself.
