In my years years of research, I have listened to people who channel entities from other planets - Pleiades, Draco, Andromedia, Sirius, Cassiopeia, Arcuturus, Lyra. Each channeler truly believes in the information they are receiving - and that it comes from a higher source. As we study metaphysics - we come to understand the multidimensional nature of our soul existence. What I have come to understand is that most channeled enitities are other aspects of our souls existing in parallel 'programs of reality' - which exist different frequency vibrations.
Realities are multi-lateral.
We exist in many at the same time. The messages received are the similar as those received by the prophets of long ago. The messages have to do with changes that are now occurring in third dimensional reality - which will bring humanity to a higher levels of consciousness. It is the end of one cycle and the beginning of another. These messages are no different than those studied in the religious and spiritual teachings of our 3D experience on physical planet Earth.
