To think but not to know more than the shadow

I've had it all wrong,
Thinking life is about
Knowing the answers
To perplexing questions.

Chasms, canyons, yawning
In the shadows of
Imperfect understanding,
Questions echo
Reverberating,
Until sanity seems
Fleeting like the last
Rays of light
On the western horizon,
Not something I can keep.

Darkness falls
On a world I cannot see,
Yet knowing it is there
Causes me to ponder.
I wonder and
This is why I write:
To give these questions
A place to roost
At night.
