Observe your thoughts, and beware of what you have in your heart and your spirit, knowing that the demons put ideas into you so as to corrupt your soul by making it think of that which is not right, in order to turn your spirit from the consideration of your sins and of God.
Like a man wearing an all-silk garment, if someone throws a dirty rag at him he leaves so as not to ruin his expensive clothes, it is with the saints, who are dressed in virtues, and avoid human glory in order not to be defiled.
Wherefore a man can know nothing about the judgments of God. He alone is the One Who takes account of all and is able to judge the hearts of each one of us, as He alone is our Master. Truly it happens that a man may do a certain thing (which seems to be wrong) out of simplicity, and there may be something about it which makes more amends to God than your whole life; how are you going to sit in judgment and constrict your own soul? And should it happen that he has fallen away, how do you know how much and how well he fought, how much blood he sweated before he did it? Perhaps so little fault can be found in him that God can look on his action as if it were just, for God looks on his labor and all the struggle he had before he did it, and has pity on him. And you know this, and what God has spared him for, are you going to condemn him for, and ruin your own soul? And how do you know what tears he has shed about it before God? You may well know about the sin, but you do not know about the repentance.
Believe that dishonors and reproaches are medicines that heal the pride of thy soul, and pray for those who reproach thee, as for true physicians of thy soul, being assured that he who hates dishonor, hates humility, and he who avoids those who grieve him, flees from meekness.
We should not miss any chance to us to say the Jesus Prayer. We must not let our mind wander in vain things. In saying the Jesus Prayer one's mind finds rest and joy. It is like small children who for the whole day run around, shouting and playing and hitting each other. But the one thing that gives them rest and great joy is when at night they find themselves in their mother's arms. This way also one's mind instead of being scattered about, out to be devoted to mental prayer.
It is up to us now to either bury our conscience under the ground, or to have it shine forth and illuminate us if we obey it. When our conscience says to us, 'Do this,' and we treat it with contempt, or it says it again and we refuse, then we are trampling it down, burying it under ground. Thus, it cannot speak to us clearly because of the weight upon it.
A person lighting a fire first has a small piece of tinder. This represents the word of the brother who has upset him. This little fire is very feeble. What significance has the word of your brother? If you put up with it you blow out the small fire, but if you begin to think to yourself, 'Why did he say that to me? I myself can answer him. If he did not want to hurt me, he wouldn't have said that and believe me, I can upset him too.' In this case, you add small pieces of wood to the fire and some other fuel like the person that lights a fire and you produce smoke which is agitation. Agitation is the movement and coming together of thoughts which stimulate the heart and make it audacious. Audacity is the taking of retribution against the person that has upset you, and this becomes insolence as Abba Mark said, 'Evil accepted in thought makes the heart audacious, but when this is revoked through prayer and hope, it makes it contrite.'
During the time of one’s confession not only the person who makes his confession is judged, but the confessor as well. In the past, confessors were practical. They did not judge on the basis of the seriousness of a transgression, but rather on the intent. They did not concentrate so much on the sins being confessed as on thinking of how to treat the repentant person’s soul.
