what impossible means

with impossible means
to improbable ends
you can't justify this
if it kills us, my friend
well we can't go back that way - or
- does it depend?
I've been practical-minded,
but that's at an end.
For practically all of my life - and I'm sick
at the slim possibility that I was right! -
I have made my decisions so certain
and slight
on the basis of what?
now, it looks like a trick of the light
how the motes flow slow motion,
exist - suspended in air
like a glittering swarm
it's so hard to believe that it's coming to this
there is nothing to fight
it's as cold and as hard
as you used to be warm.
