"Setting others free means setting yourself free, because resentment is really a form of attachment. It is a cosmic truth that it takes two to make a prisoner; the prisoner and a gaoler (Jailor). There is no such thing as being a prisoner on one's own account. Every prisoner must have a gaoler, and the gaoler is as prisoner as he is. When you hold a resentment against anyone, you are bound to that person by a cosmic force, a real though mental chain. You are tied by a cosmic tie to the thing that you hate. The one person perhaps in the whole world whom you most dislike is the very one to whom you are attaching yourself by a hook that is stronger than steel. Is this what you wish? Is this the condition in which you desire to go on living? Remember, you belong to the thing with which you are linked in thought, and at some time or other, if that tie endures, the object of your resentment will be drawn again into your life, perhaps to work further havoc. Do you think you can afford this? Of course, no one can afford such a thing; and so the way is clear. You must cut all such ties, by a clear and spiritual act of forgiveness. You must lose him and let him go. By forgiveness you set yourself free; you save your soul. And because the law of works alike for one and all, you help to save his soul too, making it just so much easier for him to become what he ought to be."
