When an archer desires to shoot his arrows successfully, he first takes great pains over his posture and aligns himself accurately with his mark. It should be the same for you who are about to shoot the head of the wicked devil. Let us be concerned first for the good order of sensations and then for the good posture of inner thoughts.'

No one can harm the man who does himself no wrong.

The Holy Scriptures do not know any distinctions. They enjoin that all lead the life of monks.

...there is nothing that has been created without some reason, even if human nature is incapable of knowing precisely the reason for them all.

Be ashamed when you sin, don't be ashamed when you repent [To repent means to have a change of heart and mind. It is not simply a feeling of sorrow ,but a psycho/spiritual growth away from evil/death and a turning to God/life]. Sin is the wound, repentance is the medicine. Sin is followed by shame; repentance is followed by boldness [ Boldness means to beg God for undeserved mercy]. Satan has overturned this order and given boldness to sin and shame to repentance.

Since it is likely that, being men, they would sin every day, St. Paul consoles his hearers by saying 'renew yourselves' from day to day. This is what we do with houses: we keep constantly repairing them as they wear old. You should do the same thing to yourself. Have you sinned today? Have you made your soul old? Do not despair, do not despond, but renew your soul by repentance, and tears, and Confession, and by doing good things. And never cease doing this.

Only those who do not fight are never wounded.
