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.
Our enemies (demons) fell because of their pride, and call us to follow them, and bring us feelings of praise. And if your soul accepts that praise, then grace will depart, until the soul becomes humble again. And so all your life you must learn the humility of Christ.
Fasting was of no benefit to that Pharisee in the Gospel, even though he always fasted two days a week, because he had adulterated it with pride and condemnation of his neighbor (Luke 18:11-12). Not that this means fasting is unprofitable. Moses, Elijah & the Lord Himself showed how beneficial it is for those who fast properly in a way pleasing to God.
Any soul which has lost its peace must repent, and the Lord will forgive its sins, and then peace and joy will visit the soul. There need be no witnesses, for the Holy Spirit is the witness of the remission of sins. Here is a sign of forgiveness: if you have come to hate sin, then the Lord has forgiven your sin.
The first step toward freedom from anger is to keep the lips silent when the heart is stirred; the next, to keep thoughts silent when the soul is upset; the last, to be totally calm when unclean winds are blowing.
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.
He who wishes to tear up the account of his sins and to be inscribed in the Divine book of the saved, can find for this purpose no better means than obedience.
It took Noah a hundred years to build his ark; log upon log he dragged to the construction. Do as he did; drag log upon log to your construction, patiently, in silence, day after day, and do not inquire about your surroundings. Remember that Noah was the only on in the whole world who 'walked with God' (Gen. 6:9), that is, in prayer. Imagine the crowding, the darkness, the stench, that he had to live in until he could step out into the pure air and build an altar to the Lord. The air and the altar you will find within you, explains St. John Chrysostom, but only after you have willingly gone through the same narrow gate as Noah.
When we stand in prayer, those unclean and unspeakable thoughts (blasphemy) assail us; but if we continue praying to the end, they retire at once, for they do not fight those who stand up to them.
We should bear in mind the fact that just as the earth cannot yield worthwhile fruit without labor, so the soul cannot acquire anything which pleases God or leads to salvation without spiritual struggles.
