"Flee for a while from your tasks, hide yourself for a little space from the turmoil of your thoughts. Come, cast aside your burdensome cares, and put aside your laborious pursuits. For a little while give your time to God, and rest in him for a little while. Enter into the inner chamber of your mind, shut out all things save God and whatever may aid you in seeking God; and having barred the door of your chamber, seek him." 

-- Anselm of Canterbury
