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.
When you intend to do something and see that your thought is perturbed, and if after invoking God's Name it remains perturbed even by a hair's breadth, know from this that the action you mean to commit is from the evil one and refrain from commiting it. For nothing done with perturbation is pleasing to God.
Every day you provide your bodies with good to keep them from failing. In the same way your good works should be the daily nourishment of your hearts. Your bodies are fed with food and your spirits with good works. You aren't to deny your soul, which is going to live forever, what you grant to your body, which is going to die.
If the soul is vigilant and withdraws from all distraction and abandons its own will, then the spirit of God invades it and it can conceive because it is free to do so.
Our soul is simple as thought, and rapid as thought or lightning. In an instant it can be wounded by sin and become attached to corruptible things; in an instant it can fall away from the love of God and its neighbor through a single unrighteous thought, through a single passionate desire, through a single malevolent thought, and, therefore, we must constantly watch our heart, lest it should incline to words or thoughts of evil, and must ever strive to preserve it in God's simplicity and purity, and in the love of God and its neighbor.
Accordingly, a man will neither be puffed up through pride, nor cast down by despair, if he uses the good things divinely bestowed on him, to the glory of the Giver; withholding his desires from the things which he knows will hurt him. And so he that would preserve himself from the wickedness of envy, from the corruption of sensuality, from the unrest of anger, from the desire of revenge, will be purified by the sanctifying power of true abstinence, and will taste the joy of imperishable delights, so that by making spiritual use of them, he will learn to change earthly possessions into heavenly, not by storing what he has received, but by multiplying more and more that which he has been given.
As long as the flesh is in full health, let us observe abstinence at all times and in every place. When it has been tamed (which I do not suppose is possible this side of the grave), then let us hide our accomplishment.
Once when a hippopotamus was ravaging the neighboring countryside the fathers called on Abba Bes to help them. He stood at the place and waited and when he saw the beast, which was of enormous size, he commanded it not to ravage the countryside any more, saying, 'In the name of Jesus Christ, I order you not to ravage this countryside anymore.' The hippopotamus vanished completely from that district as if driven away by an angel.
Let us avail ourselves of the example of that holy staretz who used to say: 'Depart, evil one; come, beloved!' Once a brother who overheard his words and supposed that the staretz was speaking to another man asked him 'With whom are you conversing, father?' And the staretz answered: 'I am driving away evil thoughts and calling the good ones to my side.' And so, if we are tempted, let us use the words of that staretz, or others like them.
Stint your stomach and you will certainly lock your mouth, because the tongue is strengthened by an abundance of food. Struggle with all your might against the stomach and restrain it with all sobriety. If you labor a little, the Lord will also soon work with you.
Abba Theon ate vegetables, but only those that did not need to be cooked. They say that he used to go out of his cell at night and stay in the company of the wild animals, giving them drink from the water he had. Certainly one could see the tracks of antelopes and wild asses and gazelles and other animals near his hermitage. These creatures always gave him pleasure.
The body can neither love nor hate. Neither can a body fall in love with a body. The capability for love belongs to the soul. When the soul is in love with the body, that is not love but desire, lust. When the soul is in love with the soul, but not through God, that is either admiration, or pity. However, when the soul, through God loves the soul, without consideration for the appearance of the body - beauty or ugliness - that is love. That is true love. For in love is life.
