It is the Emptiness...

We join spokes together in a wheel,

but it is the center hole

that makes the wagon move.

We shape clay into a pot,

but it is the emptiness inside

that holds whatever we want.

We hammer wood for a house,

but it is the inner space

that makes it livable.

We work with being,

but non-being is what we use.
               ~Tao Te Ching, 11

Ok, I get it. The center hole makes the wagon move and a clay pot holds whatever we want. Of course, the inner space is what makes the house a home. So, why is it so difficult for the mind to equate this being~non-being that is who we are?
