Fire and water do not mix, neither can you mix judgment of others with the desire to repent. If a man commits a sin before you at the very moment of his death, pass no judgment, because the judgment of God is hidden from men. It has happened that men have sinned greatly in the open but have done greater deeds in secret, so that those who would disparage them have been fooled, with smoke instead of sunlight in their eyes.
Angels are a light for monks, and the monastic life is a light for all men. Therefore let monks strive to become a good example in everything, giving no occasion for stumbling in anything (II Corinthians 6:3) in all their works and words. For if the light becomes darkness, how much darker will be that darkness, that is, those living in the world.
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.
Do not regard the feelings of a person who speaks to you about his neighbor disparagingly, but rather say to him: 'Stop, brother! I fall into graver sins every day, so how can I criticize him?' In this way you will achieve two things: you will heal yourself and your neighbor with one plaster. This is one of the shortest ways to the forgiveness of sins; I mean, not to judge. 'Judge not, and ye shall not be judged,' (Luke 6:37).
Until we have acquired true prayer, we are like those who introduce children to walking. Make the effort to raise up, or rather, to enclose your mind within the words of your prayer; and if, like a child, it gets tired and falters, raise it up again. The mind, after all, is naturally unstable, but the God Who can do everything can also give it firm endurance. Persevere in this, therefore, and do not grow weary...
A little fire softens a large piece of wax. So, too, a small indignity often softens, sweetens and wipes away suddenly all the fierceness, insensibility & hardness of our heart.
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.
As a ray of sun, passing through a crack, lights everything in the house and shows up even the finest dust, so the fear of the Lord, entering a man's heart, reveals to him all his sins.
When it is needful that a person be humbled, then not only the Superior, the sisters, strangers and near ones, but even all creation, according to the words of St. Isaac the Syrian, will rise up against that person.
Sleep is a particular state of nature, an image of death, inactivity of the senses. Sleep is one, but, like desire, its sources and occasions are many; that is to say, it comes from nature, from food, from demons, or perhaps, sometimes, from extreme and prolonged fasting, through which the flesh is weakened and at last longs for the consolation of sleep.
Let all of us who wish to attract the Lord to ourselves draw near to Him as disciples to the Master, simply, without hypocrisy, without duplicity or guile, not out of idle curiosity. He Himself is simple and not composite, and He wants souls that come to Him to be simple and guileless. For you will surely never see simplicity bereft of humility.
