" But we can influence (not compel) each other’s choices through the mediating channels of imagination and emotion. So can angels. They can’t put judgments in your mind or choices in your will, but they can put images in your imagination and feelings in your heart. (Feelings don’t compel you either; your will can choose whether to follow your feelings or not.) "
