Can't

Fire signs written in sand,
twinkle creating lava among coal
delicately dripping and dipping,
stroking and hardening in formations.

"Wait for what I have,
give me everything and nothing"
the fire sears on in gravely sand.

Flickering and flashing "fight me no longer,
crave me much deeper than you can bare
I dare you!"

I cannot, I can't give you what you want,
sizzling spurts of my strength do nothing.
"But you must, don't fear darkness,
the heat rising within."

I will not, I cannot, must not
my mind won't give in
no matter how weak I feel,
no matter how lost I am,
no matter the blood I've lost,
the pain I crave, and the pain I gave is all I have.

Deriving strength from sadness,
from distance, the fire fades
to once again only a coal.
One coal, cold and hard and black.
