Stopped

I stood in sand the color of sky
That stretched to infinity on any side,
An expanse of air or ground or cage
That constantly moved but never changed,
Rearranged exactly the same whether I
Stopped
Or turned
Or closed my eyes:
A blank page without edge or divide.
A turn to the left: no change of view.
A step and a turn brought nothing new.
Until the sand moved,
And I stopped, too.
