When you intend to do something and see that your thought is perturbed, and if after invoking God's Name it remains perturbed even by a hair's breadth, know from this that the action you mean to commit is from the evil one and refrain from commiting it. For nothing done with perturbation is pleasing to God.
Concerning fasting, do not grieve, as I have said to you before: God does not demand of anyone labors beyond his strength. And indeed, what is fasting if not a punishment of the body in order to humble a healthy body and make it infirm for passions, according to the word of the Apostle: 'When I am weak, then am I strong' (II Corinthians 12:10).
We must vigilantly guard our heart from unfitting thoughts and impressions, according to the word of the writer of Proverbs: ‘Keep thine heart with the utmost care; for out of these are the issues of life,’ (Proverbs 4:23).
We must not think that anyone slips and comes to ruin by a sudden fall; it is rather that he has been deceived by the beginnings of evil habits, or else, by prolonged mental negligence, virtue has little by little withdrawn from him, and vices have thereby grown stronger, and he has come thus to a miserable fall. For Pride goeth before destruction, and the spirit is lifted up before a fall (Prov.16:18 LXX). Just as a house never falls in ruin by a sudden shock unless there has been some long-standing fault in the foundations, or by the prolonged carelessness of the tenants, little driblets at first penetrate through and slowly undermine the walls, which, inconsequence of the old neglect, open in ever wider apertures and crumble away, and then let in the tempest of rain and storm in torrents. For by slothfulness a building shall be brought down, and through the weakness of hands the house shall drop through (Ecclus. 10:19 LXX).
My children, avoid criticism -- a very great sin. God is grieved whenever we criticize and loathe people. Let us concern ourselves only with our own faults -- for these let us feel pain; let us criticize ourselves and then we will find mercy and grace from God.
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.
Empty your mind of these two things: the belief that you are deserving of great things, or the thought that any man is beneath you. If you do this anger will never be permitted to rise up within you.
Prayer is a great good if offered up from a thankful soul; if we are steadfast in it, so that whether we receive or do not receive what we pray for we at all times give thanks to God. For since He will sometimes grant what we ask and sometimes will not, in both cases it is to our gain... For oftentimes God will delay, not as denying our prayer, but in His wisdom seeking rather for our perseverance, and desiring to draw us nearer to Himself; as a loving father when asked by his son for something will often do; withholding consent, and not from the will to refuse, but rather to encourage him in steadfastness.
But a sober and prudent man who desires to be saved, when he sees from what it is that he suffers harm, carefully preserves himself from evil remembrances, is not drawn into passionate thoughts, avoids meetings and conversations with those for whom he feels attraction and avoids every occasion for sin, fearing lest he himself ignite a fire within himself. This is the warfare which proceeds from one’s own lust, which a man brings on himself
Even if we have thousands of acts of great virtue to our credit, our confidence in being heard must be based on God's mercy and His love for men. Even if we stand at the very summit of virtue, it is by mercy that we shall be saved.
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.
The fathers have laid down that psalmody is a weapon, and prayer is a wall, and honest tears are a bath; but blessed obedience in their judgment is confession of faith, without which no one subject to the passions will see the Lord.
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.
