Fasts and vigils, the study of Scripture, renouncing possessions and everything worldly are not in themselves perfection, as we have said; they are its tools. For perfection is not to be found in them; it is acquired through them. It is useless, therefore, to boast of our fasting, vigils, poverty, and reading of Scripture when we have not achieved the love of God and our fellow men. Whoever has achieved love has God within himself and his intellect is always with God.
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.
Those who mourn and those who are insensitive are not subject to fear, but the cowardly often have become deranged. And this is natural. For the Lord rightly forsakes the proud that the rest of us may learn not to be puffed up.
No one in the face of blasphemous thoughts need think that the guilt lies within him, for the Lord is the Knower of hearts, and He is aware that such words and thoughts do not come from us but from our foes.
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.
'If our prayer is not in harmony with our deeds, we labor in vain,' Abba Moses often told the young monks. 'How are we to accomplish such harmony?' they asked him one day. 'When we make that which we seek fitting to our prayer,' explained the saint. 'Only then can the soul be reconciled with its Creator and its prayer be acceptable, when it sets aside all of its own evil intentions.'
As too many sticks often choke a fire and put it out, while making a lot of smoke, so excessive sorrow often makes the soul smoky and dark, and dries the stream of tears.
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?
The belly when filled with all kinds of food gives birth to seeds of wantonness, nor can the mind, when choked with the weight of food, keep the guidance and government of the thoughts. For not only is drunkenness with wine wont to intoxicate the mind, but excess of all kinds of food makes it weak and uncertain, and robs it of all its power of pure and clear contemplation. The cause of the overthrow and wantonness of Sodom was not drunkenness through wine, but fullness of bread. Hear the Lord rebuking Jerusalem through the prophet. 'For how did thy sister Sodom sin, except in that she ate her bread in fullness and abundance?' (Ezek. xvi. 49)
We must with unflagging zeal and care give ourselves to the pursuit of virtue, and constantly occupy ourselves in its practice, lest at any time progress may cease, and regress immediately take its place.... To cease to acquire means to lose, for the will which goes no longer forward will not be far from peril of falling back.
