One must by every means strive to preserve peace of soul and not be disturbed by offenses from others; for this one must in every way strive to restrain anger and by means of attentiveness to keep the mind and heart from improper feelings. And therefore we must bear offenses from others with equanimity and accustom ourselves to such a disposition of spirit that these offenses seem to concern not us, but others. Such a practice can give quietness to the human heart and make it as dwelling for God Himself.
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.
A brother asked Abba Isidore the priest, 'Why are the demons so frightened of you?' The old man said to him, 'Because, ever since the day I began practicing ascesis, I have striven to prevent anger from reaching my lips.'
Silence of lips is better and more wonderful than any edifying conversation. Strive to acquire humility and submissiveness. Never insist that anything should be according to your will, for this gives birth to anger. Do not judge or humiliate anyone, for this gives birth to anger. Do not judge or humiliate anyone, for this exhausts the heart and blinds the mind, and thereon leads to negligence and makes the heart unfeeling.
When anyone is disturbed or saddened under the pretext of a good and soul-profiting matter, and is angered against his neighbor, it is evident that this is not according to God: for everything that is of God is peaceful and useful and leads a man to humility and to judging himself.
The first step toward freedom from anger is to keep the lips silent when the heart is stirred; the next, to keep thoughts silent when the soul is upset; the last, to be totally calm when unclean winds are blowing.
It is necessary most of all for one who is fasting to curb anger, to accustom himself to meekness and condescension, to have a contrite heart, to repulse impure thoughts and desires, to examine his conscience, to put his mind to the test and to verify what good has been done by us in this or any other week, and which deficiency we have corrected in ourselves in the present week. This is true fasting.
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.
Not every man can be trusted when giving advice to those who seek it. We can trust only him who has received from God the grace of discrimination and who ... has acquired through great humility and long practice of the virtues an intellect blessed with spiritual insight. Such a man is in a position to advise, not everyone, but at least those who seek him out voluntarily and who question him by their own choice; for he has learned things in their true order.
Do not befoul your intellect by clinging to thoughts filled with anger and sensual desire. Otherwise you will lose your capacity for pure prayer and fall victim to the demon of listlessness.
Do not let the sun go down on the anger of your brother (Eph. 4:26); that is, let no one be angry and enraged against his brother until the setting of the sun.
