Remain aware that Lao Tzu reminds us that there is always Yin (the passive and empty component) that coexists with Yang (the active and shaping component).  The two together provide the means to total action, total responsibility, lifefulness, and lovefulness.  The importance of what is not defines the classical paradigm called enlightenment.

We join thirty spokes
To the hub of a wheel,
Yet it’s the centre hole
That drives the chariot.

We shape clay
To birth a vessel,
Yet it’s the hallow within
That makes it useful.

We chisel doors and windows
To construct a room,
Yet it’s the inner space
That makes it livable.
 
Thus do we create what is
To use what is not.
