Arabesque

I am the spine of a book, pages open on either side.

I am steel rails down a valley that two greening hills divide.

I am the corpus callosum, of two minds in every thought.

Am I sleeping or here wakeful, one eye open, one eye not?

I am the nest with two birds calling, both the same but different still,

I disperse myself in potions, both the doctor and the ill.

I am the worm who grew two wings, one of blue and one of gold,

Meeting in the middle when in flight and when in fold.

for Sunday Muse #161. This had three stanzas but I liked it better with just the two.
