Fear.

Strength, I see you're face and ponder you're existence.
Machine, robot.
Fuelled by ignorance and spitting charcoal and flame. I watch you suffer.
You're blank fury and emotionless dismay overthrows clarity.
I watch you die. Slowly painfully sinking in the bottomless pit, feeding and craving the eternal life.
Immortality, you fear death and realise that you will die, and you hold fear.
Fear grips you're soul, I watch as you pounce on distraction after distraction. The devil throws you a nice meaty stick, and I watch as you howl, disgust and dismay, when you find this awesome distraction becomes tofu.
TOFU!
Fall back, the dark shadow has no form and no matter you're strength, no matter you're ignorance, it will take you down.
You run, dark streets and you look around, you see sickness.
You see the wealthy and you see the poor, and you have made you're choice.
You want freedom, constantly running and hurting, you cannot run forever.

Someday you will perish, and you're stalker will take you down.
It is only then will you realise what you have done.
You must die to overcome you're fear.
You must reject you're learning, to become free.
Otherwise, you will suffer.
