There is a flaw in his conception. As long as we remain in a body, we will continue to have an ego. The ego has it's place, just like thte body does, because the stronger and more centered our ego is, the more we are able to connect to other people. Know thyself. In this supercontext, I would define the ego as strong and therefore more transparent to this "higher" reality, thereby allowing it to be turned on to the higher circuits and lower circuits simultaneously. Being "out there" and right here, right now at the same time. Alternity as Lilly described it. And it's there that he seems to articulate it correctly, when he says we will all be living in ecstatic bliss, not caught up too far in sci-fi uber-realities (higher circuits), without being grounded here (lower circuits). All this complex rhetoric can be distilled down to "Be here now". :)

Hmmm, I think I tend to disagree with your assertion that the ego is bound to the body. IMHO, the ego is the evolutionary side-effect of the biosurvival circuit running in a larger forebrain. It is self-awareness through higher cortical mapping and planning, but there are many techniques for subduing the influence of the ego without destroying the body. The ego allows for relationships but also limits those relationships to I-Thou. There can be no real merging of consciousness while the ego is fully intact. The supercontext, I imagine, would be a reduction of the ego as the body is pulled out of spacetime and self-consciousness becomes aware of, and merges with, universal consciousness.

I'm not doubting that the ego can be completely onliterated while still in the body... just look at anyone peaking on LSD. My contention is that getting rid of the ego entirely and permanently while still in a body is just plain stupid. The nut house if filled with people of that persuasion. The ego may be an evolutionary development just like the body is, and like the body it has its role to play. The question is what role is that? As you and I both know, that is part of what metaprogramming is all about. It's not about throwing the baby out with the bathwater, and flushing the ego down the toilet bowl of history. It's about getting the ego in alignment with our higher purpose, true will, supercontext, or whatever you want to call it. The ego is an illusion, but a useful one, especially while still living in a body that needs a locus of control in order to function safely. Becoming transhuman is not about throwing emotions or a sense of identity away either, but of embracing an expanded space of possible emotions and identities.

As Leary, Wilson, and even Crowley said, you have to have your four lower circuits stabilized before launching into higher ones. John Lilly almost died in a bicycle accident while high on Ketamine because he hadn't learned this yet. His advice is to spend more time being human while still in a human body on the planetside trip.
