From "The Man with the Blue Guitar"

XXXII

Throw away the lights, the definitions,
And say of what you see in the dark

That it is this or that it is that,
But do not use the rotted names.

How should you walk in that space and know 
Nothing of the madness of space,

Nothing of its jocular procreations?
Throw the lights away. Nothing must stand

Between you and the shapes you take
When the crust of shape has been destroyed.

You as you are? You are yourself.
The blue guitar surprises you. 

-- From "The Man with the Blue Guitar" by Wallace Stevens
