A few years ago I ran across the "Matrix" books from Val Valerian.
On the cover of Matrix V is an image that really stuck in my brain.
I didn't use the img tag because it renders it too large and I don't know how to make it fit. Maybe someone else does? (so folks don't have to click-out).
I processed that image before I read MBT and it really, really worked for me. I do not promote Valerians work. I have nothing to say about it. I only share that image as a possible illustration of a concept, and especially in the way Ted describes it above, which is my own experience. BTW: Valerian talks-up the parallel-incarnations model. I asked Tom about this once and he said, as Ted said: yes, but uncommon.
One day I was talking with a niece. That image came up. She said that she had a "dream" one time that was sort of like that image, but different in an important way. She went on to describe a sort of ice-cube-tray arrangement wherein an individual incarnation, a FWAU in MBT-speak, sat in each individual section. Above the ice cube tray was what she described as something very much like the Valerian "jellyfish" which would be the IUOC in MBT-speak. Only in her dream the jellyfish was not hard-wired to each individual ice cube/FWAU. Rather, she said, it had what looked like a single tentacle that came down and sort of "inspected" each ice cube/FWAU one at a time, sort of like sampling. She said that if one of them had something interesting going on the jellyfish would linger over it and perhaps attach to it for a while. After the "interesting" part finished, it would go on "sampling" the ice cubes.
She has NO education in metaphysics or anything at all like it. She only had a dream and happened to remember it when we were talking about the Valerian Jellyfish model. I think her dream describes very well what Ted was talking about above, the time-share model of computer processing that can be used to facilitate multiple, parallel incarnations/FWAU's by a single IUOC.
I think that when, in the Valerian Jellyfish model, a single FWAU incarnation ends, the tentacle (fibre optic cable?) sort of "retracts" into the jellyfish and the awareness that was the FWAU then sort of expands or "wakes up" (at some variable rate, depending on its level of awareness and particular "need" for transition) as the IUOC in a sort of expansion of awareness. I asked Tom about this and he said it was very much like waking from a dream. IN that process there is no "loss" of an identity, and no attendant "wrong" that would cause mourning or anything like what we sometimes think of when we consider death.
