My children, desire to purify your hearts from envy and from anger with each other, lest death should overcome you, and you will be counted among the murderers. For whosoever hates his brother, kills a soul.
All other possessions do not really belong to the one who has them or to the one who has acquired them for they are exchanged back and forth like a game of dice. Only virtue among our possessions cannot be taken away, but remains with us when we live and when we die.
Be slow and dull to idle talk, but knowing and wise in hearkening to the saving words of the Holy Scriptures. Let the hearing of worldly tales be to you as a bitter taste in your mouth, but the discourse of holy men as a honeycomb (Prov. 16.24). Be eager to imitate men of disciplined habits and do not wait to be taught each thing. Strive to attain to the greater virtues, but do not neglect the lesser ones. Do not make light of a fall even if it be the most venial of faults; rather, be quick to repair it by repentance, although many others may commit a large number of faults, slight and grievous, and remain unrepentant. Judge not the sins of others, for they have a just Judge ‘Who will render every man according to his works’ (Rom. 2.6); but be master of what is your own and lighten your own burden insofar as you have the power, for he who increases his own burden will also carry it. In repentance is salvation, but folly is the death of repentance.
When you close the doors to your dwelling and are alone you should know that there is present with you the angel whom God has appointed for each man...This angel, who is sleepless and cannot be deceived, is always present with you; he sees all things and is not hindered by darkness. You should know, too, that with him is God, who is in every place; for there is no place and nothing material in which God is not, since He is greater than all things and holds all men in His hand.
As a ray of sun, passing through a crack, lights everything in the house and shows up even the finest dust, so the fear of the Lord, entering a man's heart, reveals to him all his sins.
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.'
When we look down upon any man, because of his color, nationality, or some other shallow thing, we destroy our own souls. Since we are one with all men in Christ, we condemn ourselves when we condemn others. And since the Holy Spirit dwells in all people, when we denigrate anyone for what he is, we blaspheme the Holy Spirit, which indwells him. It is wise for a man, therefore, to avoid anyone who speaks against others because of the color of their skin or because of any other external attribute which God has given them.
And when you pray, see that you ask not for what is alien to your life, and provoke the Lord. Ask not for money, not for human glory, nor power, nor for any of the things that pass away. But seek for the kingdom of God, and all that is needed for your body will be provided; as the Lord Himself has said: Seek ye the kingdom of God, and his justice, and all these things will be added unto you (Matthew 6:33).
Learn to desire humility, for that will cover all your sins. All sin is hateful to God, but the most hateful of all is pride of heart. Do not consider yourself learned or wise, or all your toil will be lost and your ship will arrive empty at the shore.
It is more serious to lose hope than to sin. The traitor Judas was a defeatist, inexperienced in spiritual warfare; as a result he was reduced to despair by the enemy's onslaught, and he went and hanged himself. Peter, on the other hand, was a firm rock: although brought down by a terrible fall, yet because of his experience in spiritual warfare he was not broken by despair, but leaping up he shed bitter tears from a contrite and humiliated heart. And as soon as our enemy saw them, he recoiled as if his eyes had been burnt by searing flames, and he took flight...
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.
