Birds on a Lawn

Birds guard

what cannot be coerced,
defend
by not knowing they defend.
Their high fortresses
withstand all thoughts,
even the worst:
the smallest things
always learn of destruction
first.

Knowing with wings
and beaks
exactly what they do,
birds have no need
to represent it, too.
What are thoughts but air
to see through?
And without mind
birds slurp worms off the lawn
and have only one back
to be crept up on.

Next to this, my consciousness 
is confusion,
my awareness the feeling
of having too many backs
turned, 
suns streaming in on all sides
of my mind
which a descending hawk
might use to force my eyes
to blink.

What am I guarding
when I think?
