"When a man severs himself from evil, he gains an exact understanding of all the sins he has committed against God; for he does not see his sins unless he severs himself from them with a feeling of revulsion. Those who have reached this level pray to God with tears, and are filled with shame when they recall their evil love of the passions. Let us therefore pursue the spiritual way with all our strength, and God in His great mercy will help us. And if we have not guarded our hearts as our fathers guarded theirs, at least in obedience to God let us do all we can to keep our bodies sinless, trusting that at this time of spiritual dearth He will grant mercy to us together with His saints."
- Saint Isaiah the Solitary
