I don't remember where I've seen this, I probably posted it in a journal entry or something, but I absolutely adore this poem:

"Keeping Things Whole"

In a f ield
I am the absence
of field.
This is
always the case.
Wherever 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.

--Mark Strand
