4· One man reaches peace in the Lord by his godly labour; another attains the same by humility. But you should strive to obtain peace in return for both the one and the other, when anger has died in your heart through the taming of irritation. Then the word of the Scriptures will be fulfilled for you: ‘Look upon mine affliction and my pain and forgive all my sins’ (Ps. xxv. 18). May the Lord preserve your soul, your body and your spirit from all evil, from all adversity inflicted by the devil and from all fantasies, inciting rebellion of thoughts .
Holy Fathers Barsanuphius and John, Philokalia on Prayer of the Heart, p. 347.
