If anyone wants to drive out the demons, he must first subdue the passions, for he will banish the demon of the passion which he has mastered. For example, the devil accompanies anger; so it you control your anger, the devil of anger will be banished. And so it is with each of the passions.
Behold, this is the true and the Christian humility. In this you will be able to achieve victory over every vice, by attributing to God rather than to yourself the fact that you have won.
