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.
Meister Eckhart tells us that in silence we make room in our soul for God and that God delights to be in our soul when we have made room. Should we not then be building mansions of silence in our souls to welcome Love's Holy Presence.
