Composure

I am calm.
I am an amber gem
held by Spartan women
to keep their hands
in a state of courtly restraint.
I am a flame of the night
whose tranquility burns
but does not ravage.
A fire
cleansed of all wild impurities,
I dance only in place
and only on cue.
I am the hush
of the wood duck
who quails and is summoned
by no hunter's call.
I am the easy mind
of a checkmate:
I am not a sigh of relief-
I am the cool retrieval
of a fully expected win.
