“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.”
-Abba Anthony the Great.
“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 a dwelling for God Himself.”
-St. Seraphim of Sarov
As with the appearance of light, darkness retreats; so, at the fragrance of humility, all anger and bitterness vanishes.
-St. John Climacus
