The soul that wishes to live according to the will of Christ should either learn faithfully what it does not yet know, or teach openly what it does know. But if, when it can, it desires to do neither of these things, it is afflicted with madness. For the first step away from God is a distaste for learning, and the lack of appetite for those things which the soul hungers when it seeks God.
-- Abba Palladius as quoted by
Thomas Merton in The Wisdom of the Desert
