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).
Ken WilberHuman beings are born and begin their evolution through the great spiral of consciousness, moving from archaic to magic to mythic to rational to perhaps integral, and from there perhaps into genuinely transpersonal domains. But for every person that moves into integral or higher, dozens are born into the archaic.
Ken WilberWhat's my philosophy? In a word, integral. And what on earth-or in heaven-do I mean by "integral"? The dictionary meaning is fairly simple: "comprehensive, balanced, inclusive, essential for completeness." Short definition, tall order.
Ken WilberPut bluntly, the ego is not an obstruction to Spirit, but a radiant manifestation of Spirit. All Forms are not other than Emptiness, including the form of the ego. It is not necessary to get rid of the ego, but simply to live with it a certain exuberance.
