I saw this poem posted along with new poetry books at a public library, and the posting didn't mention what book or books it is from. Mark Strand owns the copyright.
KEEPING THINGS WHOLE
by Mark Strand
In a field
I am the absence
of field.
This is
always the case.
Whenever I am
I am what is missing.
When I walk
I part the air
and always
the air moves in
to fill the spaces
where my body's been.
We all have reasons
for moving.
I move
to keep things whole.
