Thomas Merton, The Wisdom of the Desert, (New York: New Directions, 1960) p. 43.
A brother came to Abbot Pastor and said: Many distracting thoughts come into my mind, and I am in danger because of them. Then the elder thrust him out into the open air and said: Open up the garments about your chest and catch the wind in them. But he replied: This I cannot do. So the elder said to him: If you cannot catch the wind, neither can you prevent distracting thoughts from coming into your head. Your job is to say No to them.
