The moon looks wonderful in this warm evening light, just as a candle flame looks beautiful in the light of the morning. Light within light. It seems like a metaphor for something. So much does. Ralph Waldo Emerson is excellent on this point.

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 existence.
