What was it, indeed.
I know I am not the only one who has gone through the possibilities of what happened that accounted for the Ancient Egyptians to come to their grasping and using of such wild knowledge.
In saying that, I know I am not the only one who has pondered that some kind of amazing use of 'energy' was occurring because of the Great Pyramid, but not necessarily the only place it happened. To have such a construction can only have been an end result of previous devices having been proved, made, and adequately performed their functions.
As for what was an all important ingredient in this production of 'energy', or the energy itself undergoing a particular transformation into something else that was all powerful and all important, we can't deny that metal was instrumental. The trick comes down to what kind of metal/s, and rather than just focusing on what was mined from the Earth or fell to Earth from meteors, that these metals were transformed by some kind of application to them seems to be hinted at in various texts.
Monatomic elements seems to be one leaning of what kinds of things were being played with way back when...if not during a very influential period of AE history, then quite possibly before the rise of AE civilization. It is a tricky thing to ponder such a thought, but due to mention of 'white bread' and other terms like it, something truly astonishing must have been developed that made its way into the magical and mystical realm of 'sacred power'.
One thing I do find fascinating is that we, as humans, are composed of over 50% of the known elements that do exist, and apparently many of them are supposed to be not good for us...and yet they are within us. Depending on what some of them actually do, and that some of them can be enhanced by what we put into ourselves - and in what way they are put into us - might offer up more clues as to why such a thing as the Great Pyramid was needed.
We can come up with a good mechanical scenario for what the pyramid did, and how it did it, but the thought of to what purpose is the real problem. I don't think total disintegration of a human body was the deal...I do think a transference of essence was the deal...and that goes beyond rejuvenation and heads into reincarnation.
And that's where we all get messed up about pyramid-use: we just find it hard to accept that 'someone' knew more than we do, and a heck of a lot earlier than we deem possible.
Ah well...flights of fancy, hey what.
