Silence is where we learn to listen, where we learn to see. Holding silence, being held by stillness, people go alone to the wilderness "to stop and see", to renew their vision, to enter the mind ground, to hear the truth, to return to the knowledge of the extensiveness of self and the truth of no self. One seeks solitude to know relatedness. There the unknown, the unarticulated, the unpredictable, the uncontrollable appear as protectors of the present.
Angels are forms, images and expressions through which the essences and energy forces of God can be transmitted; and, 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.
