Fire makes iron impossible to touch, and likewise frequent prayer renders the intellect more forceful in its warfare with the enemy. That is why the demons strive with all their strength to make us slothful in attentiveness to prayer, for they know that prayer is the intellect's invincible weapon against them.
Suppose you have ordered yourself not to eat fish; you will find that the enemy continually makes you long to eat it. You are filled with an uncontrollable desire for the thing that is forbidden. In this way you can see how Adam's fall typifies what happens to all of us. Because he was told not to eat from a particular tree, he felt irresistibly attracted to the one thing that was forbidden him.
When you see someone suffering great dishonor, you may be sure that he was carried away by thoughts of self-esteem and is now reaping, much to his disgust, the harvest from the seeds which he sowed in his heart.
Some people when praised for their virtue are delighted, and attribute this pleasurable feeling of self-esteem to grace. Others when reproved for their sins are pained, and they mistake this beneficial pain for the action of sin.
The Martyrs won Paradise through their blood; the Ascetics, through their ascetic life. Now you, my brethren, who have children, how will you win Paradise? By means of hospitality, by giving to your brothers who are poor, blind, or lame.
Be glad and rejoice that you were granted to be pious Orthodox Christians. Likewise again cry and mourn for the impious and unbelievers who walk in darkness, in the hands of the devil.
Do all in your power not to fall, for the strong athlete should not fall. But if you do fall, get up again at once and continue the contest. Even if you fall a thousand times because of the withdrawal of God's grace, rise up again each time, and keep on doing this until the day of your death. For it is written, 'If a righteous man falls down seven times' - that is, repeatedly throughout his life - 'seven times shall he rise again' [Prov. 24:16].
If you want to cure your soul, you need four things. The first is to forgive your enemies. The second is to confess thoroughly. The third is to blame yourself. The fourth is to resolve to sin no more. If we wish to be saved, we must always blame ourselves and not attribute our wrong acts to others. And God, Who is most compassionate, will forgive us.
If it is made possible, I intend to come to you in order to see the faithful gathered in Jerusalem, and especially the Mother of Jesus: they say of her that she is honorable, affable, and arouses wonder in all, and all wish to see her. But who would not wish to see the Virgin and to converse with her who bore the true God? ...With us she is glorified as the Mother of God and the Virgin full of grace and virtue. They say of her that she is joyful in troubles and persecutions, does not grieve in poverty and want, and not only does not get angry with those who offend her but does good to them still more... All who see her are delighted.
When the attention of the mind is fixed in the heart it is possible to control what happens in the heart, and the battle against the passions assumes a rational character. The enemy is recognized and can be driven off by the power of the Name of Christ.
I said to him, 'My sweet and good father, where do you receive the Eucharist on the Sabbath and the Lord's Day?' He said to me, 'Every Sabbath and every Lord's Day, an angel comes to me and gives me the Eucharist. And blessed is everyone who lives as a citizen in the desert on account of God and sees no human being -- He brings the Eucharist to them and comforts them. If they desire to see anyone, they are taken up to heavenly heights and they see them. They greet them and the hearts are filled with light. They rejoice in the Spirit and are glad in the good things they will never lack. When they see them, they are comforted, and they completely forget the afflictions that have been theirs. Afterwards they return to their places, and they are comforted for a long time, as though they had been removed to another world. Because of the great joy they have seen, they do not remember that this world even exists.'
