(From the word about anger, for example, keep anger at your friends in the region is given to the devil) Someone Isaac the monk told the following incident from his life. Once, he says, I quarreled with my brother and became angry with him. Meanwhile, sitting once for my needlework, I remembered my quarrel, repented and, worried by the fear of responsibility before God, thought: what should I do? At that time a young man came to me and, not creating, as it were, a sign of the cross, said: "You have sinned and are worried; surrender yourself to me and you will be at peace. " I, after learning that it was the devil, answered: "Go away, for you are not from God."
