Illusions

I saw the shadow cross the ground.
The flittering movement spoke of a butterfly
in flight.

Looking up, I saw not a butterfly,
but a leaf blowing in the wind.
Fall is here.

I wonder though, how many shadows
do I see, assuming I know
their source?

And, how many see my shadow,
and assume it reveals
my identity?

I wonder also, what do I see,
my shadow, me or,
what is free?
