The limbless arm

Cut loose in a branchless freedom
I lie like a limbless arm
The wound severed from the bone
I spring and coil like time
Abundance in flesh
Feeds sorrow for the soul
There is no pit to fill this whole
Swelling like a tumour
Broken as a moth
taken like a harpy from her feeding trough
I wander limbless
Steel shutters shiver, protection is free
Sand and stone fill the gap
where once was a pillar, a cardiac wrap
Put through the tubes
pump the stuff through
fill with life the heart of a shrew
