Therefore let not strange fancies disturb you, whenever they arise. Bravely observe your purpose and your upright intentions towards God. It is not an illusion when you are sometimes suddenly carried away into rapture, and then suddenly art brought back to the usual vanities of your heart. For you rather unwillingly undergo them than cause them; and so long as they displease you and you strive against them, it is a merit and no loss.
Imitation of Christ, III, 6:3
