by St. Maximus the Confessor
If you bear a grudge against anyone, pray for him and you will stop the passion in its tracks. By prayer you separate the hurt from the memory of the evil which he did you and in becoming loving and kind you completely obliterate passion from the soul. On the other hand, if someone else bears you a grudge, be generous… and humble with him, treat him fairly, and you will deliver him from the passion.
