The understanding of "evolutionary consciousness" is perhaps the most important thing lacking in spiritual practices today. Evolution means growth and development. This means that there are aspects of reality that have not yet arisen in our consciousness. But they will arise if we grow.
Ken WilberThat all oppositesโsuch as mass and energy, subject and object, life and deathโare so much each other that they are perfectly inseparable, still strikes most of us as hard to believe. But this is only because we accept as real the boundary line between the opposites. It is, recall, the boundaries themselves which create the seeming existence of separate opposites. To put it plainly, to say that "ultimate reality is a unity of opposites" is actually to say that in ultimate reality there are no boundaries. Anywhere.

Ken WilberFurthermore, it is not that Spirit is present but you need to be enlightened in order to see it. It is not that you are one with Spirit but just don't know it yet. Because that would also imply that there is some place Spirit is not. No, according to Dzogchen, you are always already one with Spirit, and that awareness is always already fully present, right now. You are looking directly at Spirit, with Spirit, in every act of awareness. There is nowhere Spirit is not.
