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.
He who speaks dispassionately of his brother's sin does so either to correct him or to benefit another. If he speaks for any other reason, either to the brother himself or to another person, he speaks to abuse him or ridicule him.
In everything we do, God looks as the aim, whether it is for Him or for some other purpose we act. So, when we wish to do something good, let us have as our aim not to please men but to please God, so as to have our eyes always fixed on Him, doing everything for Him, lest we bear the labor but lose the reward.
As water standing behind an earth dam, and finding an aperture, washes it wider and wider and filters through it, if we do not strengthen the dam, or strengthen it insufficiently, at last, with growing weakness on our part and with repeated efforts, the water gets through with greater and greater force, so that at last it becomes very difficult, and even impossible to stop it; so also with malice hidden in the heart of man: if we let it pierce through once, twice, and thrice, it will pour out more and more powerfully, & may at last break through and overflow your dam.
It is not food that is evil but gluttony; not childbearing but fornication; not money but cupidity; not glory but vainglory. If this be so there is no evil in anything that is, except wrong use, which results from our mind neglecting to cultivate our nature (the powers of the soul, and their right direction).
The enemy of our salvation especially strives to draw our heart and mind away from God when we are about to serve Him, and endeavors to adulterously attach our heart to something irrelevant. Be always, every moment, with God, especially when you pray to Him. If you are inconstant, you will fall away from life, and will cast yourself into sorrow and straitness.
That prayer may be poured forth with that fervor and singleness of heart that it ought to have, these rules must always be observed. In the first place, anxiety concerning the things of the flesh must be altogether be put away; then we must not allow to enter our minds any thought or even memory of worldly cares or business. We must cut off slanderings, vain words or many words, jestings and the like. We must root out the disturbances of anger especially, and despondency, and also tear up the
evil roots of carnal lust and avarice. And so with these and similar faults done entirely away with and cut off, - things which can also be discerned by human eyes - and with such a cleansing and purifying as we have mentioned first carried out in the sincerity of simplicity and innocence, we must lay the unshakable foundations of humility strong enough to sustain a tower which shall pierce the heavens.
I shall speak first about control of the stomach, the opposite to gluttony, and about how to fast and what and how much to eat. I shall say nothing on my own account, but only what I have received from the Holy Fathers. They have not given us only a single rule for fasting or a single standard and measure for eating, because not everyone has the same strength; age, illness or delicacy of body create differences. But they have given us all a single goal: to avoid over-eating and the filling of our bellies... A clear rule for self-control handed down by the Fathers is this: stop eating while still hungry and do not continue until you are satisfied.
Imagine how resplendently adorned, what a pure and perfect palace of the Almighty must have been the most holy soul and the most pure body of the Mother of God, in whose womb God the Word-Godhead, soul and body-came to dwell! Imagine how eternal, infinite, unchangeable is her holiness! Imagine of what reverence she is worthy, how we should glorify her!
A man of good sense, realizing how beneficial are the judgments of God, thankfully endures the tribulations they bring him, holding none guilty but his own sins. But a foolish man, when he sins and is punished, regards as the culprit of his ills either God or men, not discerning the wisdom of Divine Providence.
Wherefore, do not remember your good deeds, in order that God may remember them. Do thou first confess thy sins, it is written, that thou mayest be justified (Isaiah 43:26).
If a messenger brings an imperial or princely document to a subject citizen, the citizen does not examine the life of the bearer, whether he is rich or poor, righteous or sinful, but listens carefully to what he reads. If anyone has not heard him, he asks someone who has. So, if you have such enormous respect for an earthly ruler, how necessary it is to listen to us priests, here where the Creator of the heavenly powers speaks through us sinners.
Leaves, whether of gold or lead, placed over the eyes, obstruct the sight equally, for the value of gold does not affect the blindness it produces. Similarly, anger, whether reasonable or unreasonable, obstructs our spiritual vision.
There is nothing more burdensome and grievous then when conscience accuses us in anything, and there is nothing dearer then calmness and approval of the conscience.
