I have never considered a possible relationship between enlightenment
and evolution. If I look at enlightenment from the taoist viewpoint, I
envision it as reaching some sort of state of being where all questions
concerning the world outside drop away and I begin to live from the
inside, relegating the outside to smoke and mirrors. I might then say that
enlightenment is rebirth and that, as a thing among the myriad things,
I would begin the process of evolving once again.
If I look at evolution as the process of movement through time and
the accompanying changes to the things which comprise me, then I
can take the position that, at this moment in time, I am somewhere
on the path of evolution and that enlightment may be only a
transition in me which encompasses no knowing or understanding
and which is merely one of an infinite number of evolutionary changes
to which my components may be subjected.
