bifurcate

Love the heart bifurcates,
each room halved
then halved again.
So four chambers made
and within reside Love's seasons.
Spring's anticipation
exponential
green and greedy
to grow into
hunger's declaration of
Summer's languid passion;
sticky and sweet,
dripping in the heat
until Autumn mellows
and makes harvest
or awaits Love's fall from grace
that ripe but unreaped may rot...
forgetful but not forgot
by Winter - that crisp and steadfast
sparkles implacable as diamond,
frozen and frigid until the thaw. 
That Spring may come again.
