Prayer is the mind's dialogue with God, in which words of petition are uttered with the intellect riveted wholly on God. For when the mind unceasingly repeats the name of the Lord and the intellect gives its full attention to the invocation of the divine name, the light of the knowledge of God overshadows the entire soul like a luminous cloud.
Pray simply. Do not expect to find in your heart any remarkable gift of prayer. Consider yourself unworthy of it. Then you will find peace. Use the empty cold dryness of your prayer as food for your humility. Repeat constantly: I am not worthy; Lord, I am not worthy! But say it calmly; without agitation.
An old man was asked, 'How can I find God?' He said, 'In fasting, in watching, in labors, in devotion, and, above all, in discernment. I tell you, many have injured their bodies without discernment and have gone away from us having achieved nothing. Our mouths smell bad through fasting, we know the Scriptures by heart, we recite all the Psalms of David, but we have not that which God seeks: charity and humility.'
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.'
The deeper the contrition, the better. But however deep the contrition, never admit a shadow of doubt about forgiveness. Forgiveness is already fully prepared and the record of all sins has been torn up on the Cross. Repentance and contrition alone are expected of every man, before he too can participate in the power of the redemption of the sins of the world through the Crucifixion.
When the holy Abba Anthony lived in the desert he was beset by boredom, and attacked by many sinful thoughts. He said to God, 'Lord, I want to be saved but these thoughts do not leave me alone; what shall I do in my affliction? How can I be saved?' A short while afterwards, when he got up to go out, Anthony saw a man like himself sitting at his work, getting up from his work to pray, then sitting down and plaiting a rope, then getting up again to pray. It was an angel of the Lord sent to correct and reassure him: 'Do this and you will be saved.' At these words, Anthony was filled with joy and courage. He did this, and he was saved.
Once two brethren came to a certain elder whose custom it was not to eat every day. But when he saw the brethren he invited them with joy to dine with him, saying: Fasting has its reward, but he who eats out of charity fulfills two commandments, for he sets aside his own will and he refreshes his hungry brethren.
Do not attempt to assess the quality of your prayer. God alone can judge its value. To us, our own prayer must always appear so poor an effort, so inadequate an achievement, that the cry of the publican spontaneously rises from our lips.
You ask for some way of completely eradicating irritability. The inclination to irritability is given us to use against sin, and we were never meant to use it against our fellow men. When we do, we act contrary to our true nature.
It was said of Abba Mark the Egyptian that he lived for thirty years without going out of his cell. The priest used to take Holy Communion to him. But the devil, seeing the remarkable endurance of this man, decided to tempt him, by making him blame the priest. He brought it about that a demoniac went to the old man, under the pretext of asking for prayers. Before anything was said, the possessed man cried out to the old man, 'Your priest smells of sin, do not let him come near you any more.' But Mark, filled with the spirit of God, said to him, 'My son, everyone rids himself of impurity, but you bring it. It is written: ‘Judge not for that you be not judged.’ (Matt. 7:1) However, even if he is a sinner, the Lord will save him, for it is written: ‘Pray for one another that you may be healed.’' (James 5:16) When he had said this and when he had prayed, he drove the devil out of the man and sent him away healed. When the priest came, according to his custom, the old man received him with joy. Seeing the absence of malice in the old man, the good God showed him a marvel. When the priest prepared himself to stand before the holy table, this is what the old man related: 'I saw the angel of the Lord descent from heaven and place his hand on the priest’s head and he became like a pillar of fire. I was filled with wonder at this sight, and I heard a voice saying to me, ‘Man, why are you astonished at this? In truth, if an earthly king does not allow his nobles to stand in his presence in soiled garments, but only arrayed in glory, how much more will the divine power purify the servants of the holy mysteries who stand before the heavenly glory?’' And the noble athlete of Christ, Mark the Egyptian, became great and was judged worthy of this grace because he had not judged the priest.
The lives of men are subject to drastic changes. These changes are gradual at times; at others, lightning quick. But even those of us who enjoy long years of opulence and fame can find no consolation, no gladness, unless our heart is illumined by the steady light of peace. It is this peace that we must seek, it is for this peace that we should pray. The peace that our Lord gave to His disciples and to all those who really have faith in him.
According to the teaching of the Fathers, any impression which, touching the heart, fills it with a great irritation, must come from the region of passions. Therefore impulses which spring from the heart should not be followed at once, but only after careful examination and fervent prayer. God preserve us from a blind heart! It is well known that passions do blind the heart and screen the shining sun of the mind that we should all strive to gaze at.
It was said of Abba Arsenius that once when he was ill at Scetis, the priest came to take him to church and put him on a bed with a small pillow under his head. Now behold, and old man who was coming to see him, saw him lying on a bed with a little pillow under his head and he was shocked and said, 'Is this really Abba Arsenius, this man lying down like this?' Then the priest took him aside and said to him, 'In the village where you lived, what was your trade?' 'I was a shepherd,' he replied. 'And how did you live?' 'I had a very hard life.' Then the priest said to him, 'And how do you live in your cell now?' The other replied, 'I am more comfortable.' Then the priest said to him, 'Do you see this Abba Arsenius? When he was in the world he was the guardian of the emperor, surrounded by thousands of slaves with golden girdles, all wearing collars of gold and garments of silk. Beneath him were spread rich coverings. While you were in the world as a shepherd you did not enjoy even the comforts you now have, but he no longer enjoys the delicate life he led in the world. So you are comforted while he is afflicted.' At these words, the old man was filled with compunction and prostrated himself saying, 'Father, forgive me, for I have sinned. Truly the way this man follows is the way of truth, for it leads to humility, while mine leads to comfort.' So the old man withdrew, edified.
