I believe that angels are forms, images, and expressions through which the essences and energy forces of God can be transmitted and that, since there are an infinite number of these forms, the greatest service anyone can pay the angelic host is never consciously to limit the ways angels might appear to us.
No human being will ever have a better friend and confidant than his or her angel. Even in little things, they are always there to help you in distress, pain, unhappiness, or indecision. There is never a time when your angels are busy at something else and do not hear you; their whole concern is you and are always "on tap." Their line is never busy.
