The more wood you pile on a fire the more heat you get, and thus it is with God - the more you think on Him the more you are fired with love and fervor towards Him. He who loves the Lord is always mindful of Him, and remembrance of God begets prayer.
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.
If you wish to be delivered from shameful passions, do not behave with anyone familiarly, especially with those toward whom your heart is inclined by a lustful passion; through this you will be delivered also from vainglory. For in vainglory is involved the pleasing of men, in the pleasing of men is involved familiarity of behavior, and familiarity of behavior is the mother of all passions.
My brother, the passions are afflictions; and so the Lord does not excommunicate us because of them, but He says: 'Call upon me in the time of affliction; and I will deliver thee, and thou shalt glorify me'. Therefore, when beset by any kind of passion, there is nothing more useful than to call upon the Name of God. All we can do, weak as we are, is to flee for refuge to the Name of Jesus. For the passions, being demons, retreat if this Name is invoked.
Live very modestly. Be very humble. Don't speak idly about humility, but be like rubbish for people to step on, if you want Christ to visit you. Your heart needs to become as soft as cotton.
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.
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.
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.
Those who live in obedience are strangers to love of money. For where even the body has been given up, what is left to be one's own? Only in one way can they be harmed, namely by being ready and quick to go from place to place. I have seen material possessions make monks patient to remain in one place. But I praise those who are pilgrims for the Lord.
Let your very dress urge you to the work of mourning, because all who lament the dead are dressed in black. If you do not mourn, mourn for this cause. And if you mourn, lament still more that, by your sins, you have brought yourself down from a state free of labors to one of labor.
