The external image remains the same, but the inward image is already different. I want to say that the dissatisfaction with the usual course of life, the desire for what is better, the conviction that the best of everything can be acquired only in the Lord, the deep, warm love towards Him, the decision to serve Him alone and the readiness to sacrifice everything for Him, so as to please Him—all this should characterize your life, your spirit, constantly making it alive and bringing it into motion.

—St. Theophan the Recluse, Kindling the Divine Spirit
