JZ Knight does what many fake psychics do. She gets you to ask the question backwards from the perspective presuming 'Ramtha,' exists. Turn it around and ask, 'Ramtha,' to prove, he's real. 'Ramtha,' should be able to manifest or predict in a manner quantifiable, specific, and repeatable. Did, 'Ramtha,' ever manifest anything physical on his prime home turf, the arena? Did anything physical appear out of nothingness? No. I'm not talking about the gold coins masters supposedly found in the tank. Do you think those weren't planted there by staff?
Did, 'Ramtha,' say anything specific regarding the March 11, 2011 Japan earthquake. No. 'Ramtha,' is claimed to have made a generic statement to the effect that there would be a great shaking and Japan would move; gave no date and got the direction Japan moved backwards. RSE masters might say the quake was a, 'runner,' to warn masters to get out of Japan. Some runner! God, 'Ramtha,' killed 19,000 innocent Japanese people with that runner. Is that the kind of ascended master you want follow? 'Ramtha,' practiced a bit of retroactive prediction about the March 11 earthquake. The follow-on prediction made by, 'Ramtha,' was a cold fish – ‘he,’ said that Japan would sink beneath the ocean and UFOs would fly out of Mt Fuji. Did any of that happen? Did, 'Ramtha,' specifically pre warn that the devastating Indian Ocean quake and tsunami would occur on December 26, 2004, killing at least 230,000 people? No.
Do any of the disciplines really result in anything you can actually use in your day-to-day life? Suppose you can perfect reading cards in the affectatious way it is done on the arena floor? What do you think you can do with that skill? Trust me, if you go to the casino up the road on the Nisqually reservation, I don't think they're going to let you stare at each of your cards for a couple of minutes under the glare of a 100 Watt bulb when you play Blackjack! How would that skill serve you in the post apocalyptic TDTC?
The supposed scientific testing of JZ Knight is pretty much junk science. Milligauss fluctuations on magnetometer really don't mean anything. The magnetic field at the Earth's surface varies that much even when nothing obvious is happening. Something as mundane as a minor solar flare can cause local rapid variations in the magnetic field. To make laboratory measurements, a set of Helmholtz coils, http://en.wikipedia.org/wiki/Helmholtz_coil
, connected to a remote magnetometer, is required to generate a null field. The coils are set up to cancel the Earth's H field, and then the H field of a subject under test inside the coils may be measured. I have seen photos of JZ Knight being, 'tested,' and it was anything but a lab situation were meaningful measurements could be made. There was an eclectic box fan positioned a few feet away to cool JZ as she did her thing. There's your magnetic field Kimosabe!
So, I'd have to say I have not seen any material evidence that, 'Ramtha,' in fact exists in the first place; there's no need to prove, 'Ramtha,' doesn't exist.
As far as the disciplines go, you can learn materially similar exercises for going to the Void at a Buddhist learning center, though they will not have the same trademarked names and may be nearly cost free.
