Cultivate the Jesus Prayer and a time will come when your heart will leap with joy, just as it does when you are about to see a person who you love very much.
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.
During the divine services, and at the very moment when the Mysteries (e.g., Holy Communion) are being accomplished, this vile enemy often blasphemes the Lord and the holy Sacrifice that is being consecrated. Wherefore, we clearly learn that it is not our soul that pronounces these unspeakable, godless and unthinkable words within us, but the God-hating fiend who fled from Heaven for uttering blasphemies against the Lord there too, as it would seem. For if these shameless and disgraceful words are my own, how could I worship after receiving the Gift? How can I praise and revile at one and the same time?
I consider those fallen mourners more blessed than those who have not fallen and are not mourning over themselves; because as a result of their fall, they have risen by a sure resurrection.
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...
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.
As for uprooting your passions, begin with self-reproach and with awareness of your own weaknesses; and consider yourself to be deserving of afflictions.
