One

Expressed
It loses its expression

Defined
It loses its definition

In its emptiness
It is the cradle of all existence

In its fullness
It is creator of all things

Ever empty
It surrenders into the mystery

Ever full
It creates into the unknown

Of one source, the two differ in name
Yet both arise from one

Oneness beyond one
Herein lies the key to all mysteries
