One of the Fathers said: just as it is impossible for a man to see his face in troubled water, so too the soul, unless it be cleansed of alien thoughts, cannot pray to God in contemplation.
Fasting needn't be limited to abstinence from food alone, because true fasting is departure from evil deeds. Forgive your neighbor any insult, abstain from causing your neighbor offence, abstain from irritation, from senseless sorrows, from fear, wrath, and so on. ‘True fasting is alienation from evil, temperance of the tongue, setting aside of wrath, casting out of lust, idle talk, lies, and oath-breaking’…This is a true and pleasing fast for the Lord. Departing from these vices and from a corrupt state is what comprises a true fast.
When you ae conscious of the sweetness of divine grace working in you and when prayer operates in your heart, then you must continue in it. Do not interrupt it or rise up to sing psalms as long as God sees fit to leave its work in you, for to do so would be to leave God who is within, in order to call on Him outside yourself, as if one were to leave the heights to stoop down to the flats.
Many do good actions, but neglect the mind; they know nothing of the spiritual contests, the victories and defeats. They neglect the mind which is the eye of the soul.
I always sought out the Divine Writings, above all, the laws of God and their explanation of them by the Fathers, and the apostolic traditions, then the lives and the teachings of the Holy Fathers, and I gave my whole attention to these and so gradually learned. In them I lived and breathed...and if there was something to do to improve myself, and if I did not find it immediately in the Holy Writings, I laid it aside until I could find some teaching on this point.
Whenever we enter the church and draw near to the heavenly mysteries, we ought to approach with all humility and fear, both because of the presence of the angelic powers and out of the reverence due to the sacred oblation; for as the Angels are said to have stood by the Lord's body when it lay in the tomb, so we must believe that they are present in the celebration of the Mysteries of His most sacred Body at the time of consecration.
Praise God continually with spiritual hymns and always remain in meditation and in this way you will be able to bear the burden of the temptations that come upon you. A traveler who is carrying a heavy load pauses from time to time and draws in deep breaths; it makes the journey easier and the burden lighter.
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.
