neither

TO AND FRO in shadow from inner to outershadow

from impenetrable self to impenetrable unself by way of neither

as between two lit refuges whose doors once neared gently close,

beckoned back and forth and turned away

heedless of the way, intent on the one gleam or the other

unheard footfalls only sound

till at last halt for good, absent for good from self and other

then no sound

then gently light unfading on that unheeded neither

unspeakable home
