Prayer is a refuge for those who are shaken, an anchor for those tossed by waves, a walking stick for the infirm, a treasure house for the poor, a stronghold for the rich, a destroyer of sicknesses, a preserver of health. Prayer keeps our virtues intact and quickly removes all evil. If temptation overtakes us, it easily drives it away; if we lose some property or something else, which causes our soul grief, it removes it. Prayer banishes every sorrow, causes good humor, facilitates constant well-being. It is the mother of. love of wisdom. He who can sincerely pray is richer than everyone else, even though he is the poorest of all. On the contrary, he who does not have recourse to prayer, even though he sit on a king's throne, is the poorest of all...
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.
A haughty person is not aware of his faults, or a humble person of his good qualities. An evil ignorance blinds the first, an ignorance pleasing to God blinds the second.
In detachment, the spirit finds quiet and repose for coveting nothing. Nothing wearies it by elation, and nothing oppresses it by dejection, because it stands in the center of its own humility.
When day is done, let us give thanks both for what we have received throughout the day, and for what we have done rightly; and let us make confession of what we have not done, and of every sin, voluntary, or involuntary or even hidden from us, in word or in deed and even in our heart, that we may bring upon us God's mercy for all of them. For to examine ourselves upon what we have done is a great help against falling into the same sins again. The things you say in your hearts, be sorry for them upon your beds (Ps. iv. 5).
Let no one on seeing or hearing something supernatural in the monastic way of life fall into unbelief out of ignorance; for where the supernatural God dwells, much that is supernatural happens.
Demons often transform themselves into angels of light and take the form of martyrs, and make it appear to us during sleep that we are in communication with them. Then, when we wake up, they plunge us into unholy joy and conceit. But you can detect their deceit by this very fact. For angels reveal torments, judgments and separations; and when we wake up we find that we are trembling and sad. As soon as we begin to believe the demons in dreams, then they make sport of us when we are awake too. He who believes in dreams is completely inexperienced. 'But he who distrusts all dreams is a wise man. Only believe dreams that warn you of torments and judgments. But if despair afflicts you, then such dreams are also from demons.
Therefore with your whole soul you should acknowledge yourself as worthy of enduring more than you already endure; remember the words which Christ the Savior spoke concerning a good deed done to one’s neighbor, words which should apply equally to every offensive word or deed against one’s neighbor. Whatever you have done to your neighbor, He says, you have done to Me.
If it is a mark of extreme meekness, even in the presence of one’s offender, to be peacefully and lovingly disposed towards him in one’s heart, then it is certainly a mark of hot temper when a person continues to quarrel and rage against his offender, both by words and gestures, even when by himself.
What does it mean to be as wise as a serpent? When a serpent is attacked, it is willing to have much of its body severed, as long as it saves the head. So to be wise as a serpent means to be willing to lose everything - your wealth, your reputation, your friends - as long as you save your faith. Your faith is your head, by which you learn all truth; and by that truth your soul is set free. We should, however, recognize that the wisdom of the serpent is not enough; we must be honest and innocent as doves. Indeed it is the combination of wisdom and innocence that creates virtue. The person who is wise as a serpent can sustain the most terrible attacks and still continue to flourish as a disciple of Christ. The person who is innocent refuses to retaliate against those who make the attacks. To be as innocent as a dove means never to take revenge on those who wrong you or undermine you. Unless wisdom is tempered by innocence, one attack provokes another, and conflict continues without end. Unless innocence is tempered by wisdom, a person is so vulnerable that he will not even survive a single attack. Rest assured that no one can ever take away your faith; your wisdom guards against that. But be careful never to bear a grudge against anyone who does you wrong.
Just as over-drinking is a matter of habit, so too from habit comes over-sleeping. Therefore we must struggle with the question of sleep, especially in the early days of obedience, because a long-standing habit is difficult to cure.
The Lord often humbles the vainglorious by causing some dishonor to befall them. And indeed the first step in overcoming vainglory is to remain silent and to accept dishonor gladly. The middle stage is to check every act of vainglory while it is still in thought. The end—insofar as one may talk of an end to an abyss—is to be able to accept humiliation before others without actually feeling it.
