Here is a link to the James Thurber story "The Moth and the Star". It's a story about seeking the unseekable, impractical, almost-non-existent and how that makes you a fool and keeps your body beautiful. The link also includes Thurber's "The Owl Who Was God", which is like a mirror version of "The Moth and the Star".
Apparently, someone set "The Moth and the Star" to music.
I could connect "The Moth and the Star" to gravity and grace. Star-seeking (what the one moth does) is sort of like seeking grace. The bridge lamps (what the other moths seek) are like gravity.
We devour people and crave power in this world, because that's reality. But realisticness isn't always trustworthy.
I don't know if Thurber intended this, but one could contrast the moth, who flies to something impersonal and more or less infinitely far away, with the birds in "The Owl Who Was God", who follow the owl, something personal and tangible and present. Moth contrasted with birds, star contrasted with owl.
