The heart,
A beautiful yet incompressible locked chest that only a single key can open.
But when finally opened it continually empties, for Love falls out like darkness flows in the ever present vacuum of night.
So we search, lest our love drain away, we search for another container, the ever-emptying heart of another.
When two hearts find each other they connect in the sweetest way possible, and the spiritual ballet continues in perpetuity, continually filling and emptying into each other.

Remove one of them and the love leaks away, leaving nothing behind but a hollow heart and a hollow human longing to be full again.
