Centaur

I've recently finished reading No Boundary.

From one chapter:

To re-own the body might initially strike one as a peculiar notion. The boundary between ego and flesh is so deeply embedded in the average person's consciousness that he responds to the proposed task of healing the split with a curious mixture of puzzlement and boredom. He has come to believe that the boundary between the mind and body is unalterably real, and thus he can't figure out why anyone would want to tamper with it, let alone dissolve it.

As it turns out, few of us have lost our minds, but most of us have long ago lost our bodies...

Indeed, my body seems just to dangle along under me. I no longer approach the world 'with' my body but on my body. I'm up here, it's down there, and I'm basically uneasy about just what it is down there.
It seems to me that the Alexander Technique offers excellent means to dissolving this ego/body boundary, it applies to the centauric level.
