The intellect joined to God for long periods through prayer and love becomes wise, good, powerful, compassionate, merciful and long-suffering; in short, it includes within itself almost all the divine qualities. But when the intellect withdraws from God and attaches itself to material things, either it becomes self-indulgent like some domestic animal, or like a wild beast it fights with men for the sake of these things.
--St. Maximus the Confessor
