Fasting, while of value in itself, is not something to boast of in front of God, for it is simply a tool for training those who desire self-restraint. The ascetic should not feel proud because he fasts; no artist ever boasts that his accomplishment is simply due to his tools; but he waits for the work itself to give proof of his skill.
When we fervently remember God, we feel divine longing well up within us from the depths of our heart. The evil spirits invade and lurk in the bodily senses, acting through the compliancy of the flesh upon those still immature in soul. According to the Apostle, our intellect always delights in the laws of the Spirit (cf. Rom. 7:22), while the organs of the flesh allow themselves to be seduced by enticing pleasures. Furthermore, in those who are advancing in spiritual knowledge, grace brings an ineffable joy to their body through the perceptive faculty of the intellect. But the demons capture the soul by violence through the bodily senses, especially when they find us faint-hearted in pursuing the spiritual path. They are, indeed, murderers provoking the soul to what it does not want.
To those who are just beginning to long for holiness, the path of virtue seems very rough and forbidding. It appears like this, not because it really is difficult, but because our human nature from the womb is accustomed to the wide roads of sensual pleasure. But those who have traveled more than half its length find the path of virtue smooth and easy. For when a bad habit has been subjected to a good one through the energy of grace it is destroyed along with the remembrance of mindless pleasures; and thereafter the soul gladly journeys on all the ways of virtue. At the beginning of the struggle, therefore, the holy commandments of God must be fulfilled with a certain forcefulness of will (cf. Matt. 11:12); then the Lord, seeing our intention and labor, will grant us readiness of will and gladness in obeying His purpose. For 'it is the Lord who makes ready the will' (Prov. 8:35, LXX), so that we always do what is right joyfully. Then shall we truly feel that 'it is God who energizes in you both the willing and the doing of His purpose' (Phil. 2:13).
The husband and wife must lay virtue, and not passion, as the foundation of their love, that is, when the husband sees any fault in his wife, he must nudge her meekly, and the wife must submit to her husband in this. Likewise when a wife sees some fault in her husband, she must exhort him, and he is obliged to hear her. In this manner their love will be faithful and unbroken, and thereby having mutually composed their happiness, they shall take pleasure in the virtue.
Those who meditate unceasingly upon the holy and glorious name [of Jesus] in the depths of their heart can sometimes see the radiance of their own spirit-intelligence. For when the mind is profoundly concentrated on this invocation, we feel experientially how it starts burning off all the layers of dirt that normally suffocates the soul.
A brother asked the abbot Pastor, saying, 'If I should see my brother’s fault, is it good to hide it?' The old man said to him, 'In what hour we do cover up our brother’s sins, God shall cover ours: and in what hour we do betray our brother’s shames, in like manner God shall betray our own.'
A wise elder gives the following advice to monks and youth alike: 'Avoid eating foods which are to your liking, but, preferably, eat the simplest foods, and be thankful to God, Who also sends you these.'
As wax cannot take the imprint of a seal unless it is warmed or softened thoroughly, so a man cannot receive the seal of God's holiness unless he is tested by labors and weaknesses. That is why the Lord says to St. Paul: 'My grace is sufficient for you: for My power comes to its fullness in your weakness'; and the Apostle himself proudly declares: 'Most gladly therefore will I rather glory in my weaknesses, so that the power of Christ may rest upon me' (2 Cor. 12:9).
An elder prescribes the following rule of conduct for the monastic table: 'When you sit to eat, brother, do not be overcome by the demon of gluttony, which compels you to eat in a disorderly way and in haste and to desire to taste many kinds of food together. Learn to eat modestly and in an orderly way and maintain a measure of restraint.'
Monastic life is called the art of arts and the science of sciences; for it does not bring perishable blessings akin to the things of this world, which drive the mind from what is best and engulf it; but monk hood promises us wonderful and unspeakable treasures which the ' Eye that not seen, nor ear heard, neither have entered into the heart of man' (1 Cor. ii. 9). Hence, ' we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world' (Ephes. vi. 12). If therefore present existence is but darkness, let us flee from it, let us flee by returning our mind and our heart. Let us have nothing in common with the enemy of God, for 'whosoever will be a friend of the world is the enemy of God' ( James iv. 4). And who can help the enemy of God ? Therefore let us imitate our fathers and, like them, let us seek the treasure existing within our hearts and, having found it, let us hold fast to it in doing and guarding - for which task we were destined from the beginning.
We came from Palestine to Egypt and went to see one of the fathers. He offered us hospitality and we said, 'Why do you not keep the fast when visitors come to see you? In Palestine they keep it.' He replied, 'Fasting is always with me but I cannot always have you here. It is useful and necessary to fast, but we choose whether we will fast or not. What God commands is perfect love. I receive Christ in you and so I must do everything possible to serve you with love. When I have sent you on your way, then I can continue my rule of fasting. The sons of the bridegroom cannot fast while the bridegroom is with them; when he is taken away from them, then they will fast.'
Keep from prying into other people's affairs, for such prying gives occasion for slander, judgement and other grievous sins. Why do you need to be concerned about others? Know and examine your own self.Recall your past sins and purge them with repentance and contrition of heart, and you will not look at what other people do.
Abba Poemen also said this about Abba Isidore that whenever he addressed the brothers in church he said only one thing, 'Forgive your brother, so that you also may be forgiven.'
Grace is the food and clothing of the saints. It wakens grief in a man's heart, making him dissatisfied and moving him to seek the reason of this dissatisfaction. Grace gives sorrow and grace comforts; showing us the poverty of all things, it engenders in us a repentant sorrow for having fallen short of the love of God... One who is possessed by such sorrow will always grieve, for he thinks of God's offended love and not of the fear of hell. It is a grief of love.
