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.
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.
It is not possible for a man to control his anger when abused, or to overcome trials with patience when afflicted, if he is not willing to take the last and lowest place among other men.
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.
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.
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.
Empty your mind of these two things: the belief that you are deserving of great things, or the thought that any man is beneath you. If you do this anger will never be permitted to rise up within you.
Of the Only Case in Which Anger is Good... But we have a use for anger most properly planted within us, and for this use alone it is profitable and healthful for us to entertain it, namely, when we burn with wrathful indignation against the lustful motions of our own hearts, and are enraged to find that those things which we should be ashamed to do or to speak of before men have found admittance into the secret places of our minds. We may then well dread and fear exceedingly the presence of the Angels and the Omnipresence of God Himself, and His all-seeing Eye from which no secrets of our hearts can lie hid.
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.
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.
