A poem
is when you have the sky in your mouth.
It is hot like fresh bread,
when you eat it,
a little is always left over.

A poem
is when you hear
the heartbeat of a stone,
when words beat their wings.
It is a song sung in a cage.

A poem
is words turned upside down
and suddenly!
the world is new.

I'm all too conscious of the change,
nothing strange, and nothing never felt before
not a shock,
perhaps the clicking of a lock
the subtle closing of a door,
a key has turned,
that well worn latch is dropped once more,
on what is done, a green and fertile time,
I hear the chimes,
which ring and sing a tune I know full well,
a tolling bell
for autumn
