God is Silence. There is a silence of the tongue, a silence of the whole body. There is a silence of the soul and the spirit. The silence of the spirit is when all its movements are stirred solely by Being; in this state it is truly silent, aware that the silence which is upon it is itself silent.
As humans we respond to symbols. We express divine Beauty and insight in our art. If there is a preponderance of art depicting angels with wings, obviously this symbolizes something real within the collective consciousness. Angels appear to humans according to human capacity to accept and understand the appearance. The angels inspire, and that is what is left in our heart after an angel experience.
