to and fro in shadow from inner to outer shadow

from impenetrable self to impenetrable unself
by way of neither

as between two lit refuges whose doors once
neared gently close, once away turned from
gently part again

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
-Samuel Beckett Libretto for Neither (1977)
