The old man (Abba Moses) was asked, 'What is the good of the fasts and watchings which a man imposes on himself?' and he replied, 'They make the soul humble. For it is written, ‘Consider my affliction and my trouble, and forgive all my sins’ (Psalm 25:18). So if the soul gives itself all this hardship, God will have mercy on it.'
How can one say that a man has attained purity? - When he sees all men as being good, and when none appears to him to be unclean and defiled - then he is indeed pure in heart.
For this present life is but a way by which we travel towards our heavenly home. And because of this we are, in the inscrutable wisdom of God, wearied by frequent disquiet, so that we may not come to love the way more than our home. For there are travelers who when on their way see some smiling field, while they delight in its beauty, they slow their steps and turn aside from the straight path they had begun. The Lord therefore has made the way of this world hard for His Elect in their journey to Him, so that none of them may take his rest in this life, enjoying the beauty of the way, but may hasten speedily towards Him rather than linger by the way; or lest, delighting in the way, they come to forget they once longed for their heavenly home.
Prayer offered up at night possesses a great power, more so than the prayer of the day-time. Therefore all the righteous prayed during the night, while combating the heaviness of the body and the sweetness of sleep and repelling bodily nature.
Let the impatient be told what the Truth says to His elect: `In your patience you shall possess your souls.' Truly, we are so wonderfully created, that reason possesses the soul, and the soul possesses the body. But the soul is dispossessed of its right over the body, if it is not first possessed by reason. Therefore, the Lord has pointed out that patience is the guardian of our estate, for He taught us to possess ourselves in it. We, therefore, realize how great is the fault of impatience, seeing that by it we lose even the possession of what we are.
God often permits virtuous men to be tried by something: He permits temptations to rise up against them on all sides... Whether these trials come from men, demons or flesh, let it be a cause for thanksgiving. For God cannot show his favor to a man who desires to dwell with Him, except by sending him trials for the sake of truth; just as no man can become worthy of this greatness... without the grace of Christ... St. Paul plainly calls it a gift... 'For unto you it is given in behalf of Christ, not only to believe in Him, but also to suffer for His sake' (Phil. 1:29).
Pray before your body takes rest on your bed... If you are tempted, make the Sign (of the Cross) on your forehead reverently… for this is a known and tested weapon against the Devil.
Just as we must beware of overeating, so too we must beware of excessive temperance or abstinence. Excessive temperance weakens the body, destroys wakefulness, coolness and freshness which are indispensable for vigilance, and which fade and weaken when the physical powers succumb and fail. If you force a weak body to labor beyond its powers, you subject your soul to double darkness, and lead it into confusion (and not relief)...
You know that evil entered into us through the transgression of the commandments. Hence it is obvious that by keeping them, evil departs from us. But without the doing of the commandments we should not even aspire or hope for purity of soul, because at the very outset we do not walk on the path that leads us to purity of soul. Do not say that God can give us the grace of purity of soul even without our keeping the commandments.
When patience greatly increases in our soul, it is a sign that we have secretly received the grace of consolation. The power of patience is stronger than the joyful thoughts that descend into the heart. Life in God is the downfall of the senses; when the heart lives, the senses fall away. The resurrection of the senses is the deadening of the heart; when the senses are quickened, it is a sign that the heart has died to God.
The man of Christ embarks upon the path of divine perfection by overcoming, with the aid of evangelical virtues, the sin and evil within him and in the world around him. He constantly marches on from one good to another, from smaller to greater, from greater to greatest. In this progress he never pauses, for any delay would bring spiritual stagnation, numbness, death. Through every pure thought, every holy sentiment, every good desire and kindly word, he progresses toward resurrection, immortality, eternal life.
