hidden inside

A beast holds me captive, thirsty for the taste of air.
The cage of which I keep him is made of flesh and bone.
For he is trapped within myself, hidden in my core.
Inaudible screams fill my lungs from my suffrage.
No!
It won't be allowed a home here anymore.
I search for strength, I prod the monster with all my firey power.
The beast is more than a mortal can bare.
Bones break, shattered glass.
Veins burst, broken damns.
Skin tears, ripped apart.
I'm going under, drowning in agony.
Although I can barely breathe, I was not defeated.
I let the beast breathe air, taste freedom.
For although it maybe true that man is his own worst enemy; it may also be said that the beast within is also a friendly, deadly, survival necessity.
