“If we see that someone is looking at us with anger, we need to pray in thought for him that the Good God would bring him peace. This helps very much in winning over a person who has enmity toward you. An enemy can be won over like this: with gifts and a kind word. Then the Holy Spirit casts out the evil spirits that have taken him captive, and he makes peace.”
(Elder Proclu+ of Romania in pravoslavie.ru)
