Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
Go to the tombs and see that the assurance of men is nothing. Why then does man who is dust indulge in vainglory? Why does he who is all stench exalt himself? Let us therefore weep for ourselves while we have time, lest, at the hour of our departure, we be found asking God for extra time to repent.
If Nabuzardan, the court cook of the King of the Babylonians, had not gone to Jerusalem, then the Temple would not have burned (cf. 2 Kings 24), That is to say, a person’s mind is not attacked by the flames of carnal pleasures, if a person is not conquered by gluttony.
Fear is a rehearsing of danger beforehand; or again, fear is a trembling sensation of the heart, alarmed and troubled by unknown misfortunes. Fear is a loss of assurance.
Do not hesitate to go late at night to those places where you usually feel afraid. But if you yield only a little to such weakness, then this childish and ridiculous infirmity will grow old with you. As you go on your way, arm yourself with prayer. When you reach the place, stretch out your hands. Flog your enemies with the name of Jesus, for there is no stronger weapon in heaven or earth. When you get rid of the disease of fear, praise Him who has delivered you. If you continue to be thankful, He will protect you for ever.
Do not be surprised that you fall every day; do not give up, but stand your around courageously. And assuredly the angel who guards you will honor your patience, while a wound is still fresh and warm it is easy to heal, but old, neglected and festering ones are hard to cure, and require for their care much treatment, cutting, plastering and cauterization. Many from long neglect become incurable. But with God all things are possible...
If you speak of pagan abuses, these abuses do not make our veneration of images loathsome. Blame the pagans, who made images into gods! Just because the pagans used them in a foul way, that is no reason to object to our pious practice. Sorcerers and magicians use incantations and the Church prays over catechumens; the former conjure up demons while the Church calls upon God to exorcise the demons. Pagans make images of demons which they address as gods, but we make images of God incarnate, and of His servants and friends, and with them we drive away the demonic hosts... If the Scripture says, The idols of the nations are silver and gold, the work of men's hands (Ps. 135:15), it is not forbidden to bow before inanimate things, or the handiwork of men, but only before those images which are the devil's work.
Meekness is the fellow-worker of obedience, the guide of the brotherhood, a bridle for the enraged, a check to the irritable, a minister of joy, the imitation of Christ, something proper to angels, shackles for demons, a shield against bitterness.
