Hello Alamo-Girl! I suspect it isn't corporeal at all, in the sense of a bodily organ. I suspect it is something that is carried by a universal field, and can be accessed via the brain if we so direct it. But I certainly haven't worked out all the details yet!
In general, I think that consciousness is field-like at the level of the individual, and that moreoever there is such a thing as collective consciousness. It seems there are many instances of what appears to be collective consciousness in the natural world; e.g., the behavior of the social insects for instance. Also there seem to be instances of it in the human world, e.g., in what is known as "public opinion," or what we mean by zeitgeist or the spirit of the age for examples.
Dr. G. has suggested that the Bauer life principle also requires a field, at the organismic level, and also at the universal level. And of course, consciousness -- or at least rudimentary sensation or awareness -- is a property of every living being.
But for me, this is merely food for speculation at this point! :^)
Thank you so much for writing, and for your excellent posts today. Unfortunately, I've been a little tied up with work projects :^( , so have not been able to jump in as much as I'd like. (This working for a living business "is for the birds!" LOL!!!)
According to M-string theory there are seven extra dimensions that we have and don't know what to do with. Perhaps we use them after all. In dimension X we would all be a millimeter away all the time. Speculate away, but we will require laboratory data at some point.
Thank you so much for your excellent insight!
