parallels and metaphors

I hurl my heart to halt his pace,
To quench his thirst I squander blood;
He eats, and still his need seeks food,
Compels a total sacrifice.
His voice waylays me, spells a trance,
The gutted forest falls to ash;
Appalled by secret want, I rush
From such assault of radiance.
Entering the tower of my fears,
I shut my doors on that dark guilt,
I bolt the door, each door I bolt.
Blood quickens, gonging in my ears:

The panther's tread is on the stairs,
Coming up and up the stairs.
-Sylvia Plath (of course)

Totally worthwhile purchase. Buy it.
