All the angels are amazed at humans, who through their holy works appear clothed with an incredibly beautiful garment. For the angel without the work of the flesh is simply praise; but the humans with their corporeal works are a glorification! Therefore the angels praise humans' work.
I started to compose the opening of "Fos" (light) and I had the idea of a string trio playing in the distance which would represent the soul yearning for God. The choir represented God in uncreated energies. This yearning choir is played by the string trio which is cut off by the joy/sorrow chord by the choir singing the word "Fos," light, light, light, light, light -- until it becomes an expanded light separated from all yet united to all, and moving straight into the second section, Doxa: symbolizing the glory of that Light filling everything with light.
