a definition of desire

Desire (n.)
a self-devouring snake,
its scaly tail convulsing in its fangs;
whatever satiety it feels is fake;
there’s not even a momentary break
as it ingests its own abdomen’s pangs

for emptiness alone fulfills Desire,
which, eating itself, eats you along the way.
what’s more to say?
you’re empty of, or else feeding, Desire;
if neither, you’re entirely a liar.
