If you are holding a grudge against someone, pray for him so that the prayer — in banishing your sorrow from the inflicted hurt — halts any rancor developing within you. If you are friendly and loving, you will completely drive out this passion from your soul. When another person is angry with you, be gentle and humble with him, fraternize in a friendly spirit, thereby helping him to rid himself of malice.
