In the final chapter of “The Eye of Spirit”, Ken Wilber describes in a wonderfully simple and rich way the essence of the nondual view. It is probably the most elegant description of it that I have found anywhere.
He also frames crusifiction and resurrection in a way that makes a good deal of sense to me.
Crusifiction can be seen as the death of the (impression) of our human selves as somehow separate and fixed. It is the death of the separate self.
And resurrection is the realignment and reorganization of our human self – on all levels, physical, energetic, emotional, mental, behavioral – in this new context. It is the transformation of the human self that naturally occurs when Existence is aware of itself as a whole, when we live from Big Mind.
