Carmen Boulter, much like Omm Sety, has spent her life pursuing an obsession with ancient Egypt, that dates back to early childhood. Traveling extensively there, and studying its sacred sites, she has been able to connect many pieces of her past life memory to physical locations, and put forth cogent theories on the land and its secrets.
In this interview she puts forward the tantalizing notion that the pyramids were actually functioning devices, rather than tombs. By putting them into a broader context of surrounding structures, she posits that they were an energy system, focusing sound and light to power their mysterious technology. Her description of the pyramids as sonic resonators reminded me of something I recently read about the Mayans possibly using their pyramids to create sound.
SIT on the steps of Mexico's El Castillo pyramid in Chichen Itza and you may hear a confusing sound. As other visitors climb the colossal staircase their footsteps begin to sound like raindrops falling into a bucket of water as they near the top. Were the Mayan temple builders trying to communicate with their gods?
The discovery of the raindrop "music" in another pyramid suggests that at least some of Mexico's pyramids were deliberately built for this purpose. Some of the structures consist of a combination of steps and platforms, while others, like El Castillo, resemble the more even-stepped Egyptian pyramids.
She also references Walter Cruttenden's theories on precession and the Great Year. According to Cruttenden, ancient writings across many cultures describe great cycles of time in which Earth civilizations rise and fall, volleying between periods of enlightenment and degradation. This, according to Cruttenden, is why some of our most ancient recorded cultures seem to have been more advanced than those that followed them; our current age reaching its nadir during the dark ages. He also posits that our sun and Sirius are actually a binary star system, explaining our cross-cultural obsession with that star. I found two excellent interviews, here and here, with Cruttenden, on Conscious Media Network, in which he thoroughly explains his theories.
