Light filling everything with light

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.
