It seems to me to be a metaphor for the human soul, the singular light within the great general light of existence. Or it seems like poetry within language. Perhaps wisdom within experience. Or marriage within friendship and love. I'll try to remember to use this. I believe I see a place for it in my thoughts on Hagar and Ishmael. Their time in the wilderness seems like a specific moment of divine Providence within the whole providential regime of Creation.
