The silicon in sand is learned
by crystal system, organized
into branches and the seed
crystal is cubic imagine
diamonds in the grains
imagine cut
against the grain a glass tree
doesn't know enough
of crystal symmetry to grow
back imagine it opens
a book leaves to pages
to learn only half
how to help the other
half how to dissociate
ions scattered across the earth
crust never enough.
This is how sand is made.
