The graph is quite elegant and beautiful.Thanks for bringing that session up, Gaby. I went back through the sessions and checked the references to "bodies", and aside from the one you mentioned, I only found one other:
Matching these to what Laura wrote in "The Wave", it seems that the correlation is:
Physical center = genetic body.
Spirit center = psychic/consciousness body.
High soul family = thought center.
So, it appears that Gurdjieff attributed an intermediate state of development of consciousness as a separate "body" - ie. it's very likely that the 'astral' and 'mental' bodies are the same thing: the psychic/etheric/consciousness body.
Luc's article regarding St Paul's Journey Towards Communion with God makes reference to Ashworth's diagram of the process of coming into communion with the Holy Spirit:
For Gurdjieff, "adulthood in Christ" was to have all 'four' bodies, but perhaps the "first instalment of the spirit", thought to signify the conception and beginning of the growth of the 'astral' body, is really just the psychic/consciousness body changing from a quiescent or 'latent' state into a more active form at the 'calling' of the Thought Centre of Being (High Soul Family).
In the same way, at a later point of development just prior to the "coming of age", certain unique changes in consciousness were assumed to be due to the formation of a 'mental' body, when in reality it's just the final step of the process before the psychic/consciousness body is 'born' into a permanently active state, the call of the Thought Centre of Being is answered, the "prodigal son" returns to the High Soul Family, and "adulthood in Christ" in achieved.
Might be worth asking the Cs about this. If this is the case, then, as I see it, the logical progression is that neutrino (and photon?) particles, having mass, are related more to the physical body (perhaps as emanations/auras?) and the "information density" and "orientation" of the neutrinos/photons are perhaps related to the psychic/consciousness body, which then acts like a 'morphogenetic field'.
If so, I hope my psychic/consciousness body will do my head a favour and make it stop hurting now.
We can even see how the future spirit goes back and installs itself.
That the moving towards the potential of spirit in itself, creates the magnetic force that can reach backwards and uplift to wards its "future" birth.
