i don't know how to cease to exist

if you rewind our tapes to the start
what does the beginning look like?
is the end simply sealed off
or does it hang frayed and torn?
maybe the beginning reaches the end
and has no real finish or start.
it might just be as simple
as a cord with two ends
and nothing to define them
except for themselves and what they are.
simply ends of what lies between.
or they could be constantly changing,
stretching, twisting, growing,
redefining where we end and
where what we are begins.
