the theory of aspiration

I have studied lift and thrust,
turbulence and velocity.
Like a Jesuit I have been devoted,
like DaVinci, entranced.
I have learned that I must hollow
each and every bone,
scrape away the marrow,
grow wings of steel or down.
Then when I’m abandoned
in the place where science bows-
there is where the fetters fall
and the currency is faith.
I will circle, seek the updraft
that will breathe beneath my wings
and lift me far beyond
these silvery feathers that I rain.
