Greetings,
Perhaps the pyramid, like a prism, concentrates light into various energy bands, some it transmits, some it receives, and therefore the pyramid serves in all the processes you all offer. It condenses light into energy which is used in several ways?
An intriguing variation on this theme is the work of C. Henry, U of the Commonwealth of Virginia, who stacks transluscent spheres into pyramidal piles and sees images of human forms--faces, buddhas, etc. as they reflect onto/into one another. In one speculation he has 2 pyramids of large spheres, pyramids base to base and ends up with a close replica of the Venus of Willendorf!He also comes up with a diagram that encompasses the form of a giza pyramid in its center but is far more extensive than just the pyramid, which might illustrate the energy field around the pyramid?
I don't understand it, but a university seems to be paying him for his work, and looking at the images is mind-boggling. I find his website with a search of << VA pyramid spheres >> on google.
Enjoy!
