The Wise Man, Pure and Still

Most perfect, yet it seems
Imperfect, incomplete:
Its use is not impaired.
Filled up, and yet it seems
Poured out, an empty void:
It never will run dry.
The straightest, yet it seems
To deviate, to bend;
The highest skill and yet
It looks like clumsiness.
The utmost eloquence,
It sounds like stammering.
As movement overcomes
The cold, and stillness, heat,
The Wise Man, pure and still,
Will rectify the world.
