All life is a form of cosmic celebration. What moves the stars through the heavens, the Earth through its seasons, and human beings through stages of growth and learning -- all is celebration. Look at the birds flying here and there, the flowers blooming, and the trees changing colors in the fall. It's all celebratory. We have only to express and become, ourselves, celebration.
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.
