Why must a heart beat?

To keep a rhythmic marching time through life?
That common tempo keeping order in
our lawless world of hate and fear death.
Each heartbeat rallies troops across the globe,
a single feature shared in every life,
an army built on spirit, crying out
with every thump that we are one.

But what must hearts beat for?

To beat we mean to say 'to fight,'
and for what better cause to fight than love?
That painful pleasure wielding power both
to wreck lives and create them,
the strength it gives to those from whom it stole in battles past.
Enamoured and encased in armour,
steeled against the pain before
as drums beat faster
palms grow sweaty
the tempo quickens
gazes steady
you brace and lean in
gently
and surrender to his kiss
as he gives in to yours,
your battle won by both
as both your drums keep time in perfect synchrony
your breaths the perfect melody that keep
the perfect peace.
