So a man must be pervaded with the divine presence, and be shaped through and through with the form of the God he loves, and be present in Him, so that God's presence may shine out to him without any effort. What is more, in all things let him acquire nakedness [detachment], and let him always remain free of things. But at the beginning there must be attentiveness and a careful formation within himself, like a schoolboy setting himself to learn.

(Meister Eckhart)
