The Chrysalis of Chang-Tzu

I dreamed I was a butterfly
buffeted about my meadow
with tired wings
and memories of leaf-eating
before wrapping myself in silk to sleep.

I awoke as Chang-Tzu
under silk sheets
and ready for breakfast
on my windriven mountain.
but wait.

Am I Chang-Tzu
dreaming I am a butterfly
am I a butterfly dreaming
I am Chang-Tzu?

Let me sleep on it.
