For a ling time I have been fascinated by the "light surah" in the Quran (Surah 24:33). Here is a translation (I don't know any Arabic!).
"God is the light of the heavens and the earth. The parable of his light is, as it were that of a niche contained in glass, the glass like a radiant star."
I am the niche and God offers light from his being, if I am willing and able.
As a reminder, in a our room there is a large glass, shining with a gentle blue.
