Insidious Spirit.

Dark, purulent, festering soul.
Oh how I wonder daily,
on what do you dine.
How do you survive?
Do you suck one's inner life?
You truly are Satan's spawn.
Sinful spirit, you lie dormant
until a glorious glimmer of hope
opens itself to your murk.
Then you pounce as a feral feline
silently sucking the good.
Feasting on hopes and dreams,
sending them forever hell-bound,
Into perennial darkness.
