In Vastness I Transfigure

Nothing in life could prepare me for such unendingness.
The cadence of my heart began to swell as I beheld what no 
man had ever before.
A simplistic procedure now the bane of my entirety.
From sternum to pelvis, the incision cleaves the sky above 
the silent tomes within.
And my eyes beheld such vastness that I had never know 
before.
This madness thus made flesh beneath me stretches beyond 
comprehension.
"Do these mortal eyes deceive?" I question as I kneel 
before eternity.
By what hands and through what means was this monstrosity, 
this endlessness entombed beneath the flesh of a man?
This index of untold dimensions and length containing every
 moment and thought of not only he, but of we the entire 
race.
Our very existence cataloged like fables in paper and ink.
Can such a word callous hearts such as it now shall mine 
forever?
Existence?
If we feeble things can call it such.
Enveloped in shadow, my heart in disarray, I descend 
through endlessness within.
My very purpose now in question for I remain so small 
amidst their glory (the stars).
The edge of the scalpel caresses my throat, a means to an 
end in fear of all I have known.
I have now only the screams of my former physical self.
The sound of its suffering comforts me for it is all I know
 in this infinite darkness.
