Evolution occurs in the world of time and space and form, whereas Spirit's primordial nature is finally timeless and Formless, prior to the of evolution but not other to it. We do not find Spirit or Emptiness by reaching some evolutionary Omega point in time, but rather by stepping off the cycle of time and evolution altogether (or ceasing to contract into it).
