In the 16th century John Dee and Edward Kelly received very advanced information for communicating with the angelic or as I like the more modern term, alien entities.
It seems that more and more people are finally getting it that angels are really a species of aliens. If the UFO community would join forces with the darker side of the occult without fear then they would be very astonished that both groups are studying the same thing but going in a parallel direction.
There are many species of inter dimensional aliens of advanced intelligence all around us. The best way to try and understand this if you are a novice is to think of communication in the alpha, theta, and gamma brain wave states by using brainwave entrainment like Isochronic tones or bianary beats during a meditation session along with the use of specific geometric symbols.
Many rituals of this nature involving these symbols are usually drawn on the ground as an interface with the subconscious mind. When those symbols are used in a 3 dimensional form then they can harness life fore energy in various ways. The terms Vril, Chi, Orgone , zero point energy and even dark matter are other terms for the same energy. Our thought can manipulate this energy into whatever you can imagine.
