Channeling
A mental process in which the individual who is channeling partially or totally sets aside waking consciousness to act as a vehicle through which disembodied spirits in the astral realm or beings from outer space can communicate. The ascended masters teach that the only legitimate communion is with the ascended saints of the Great White Brotherhood and that psychic channeling is dangerous because it seriously depletes the channel, as well as those present, of “ectoplasm” (thought to produce materialization or telekinesis)—the vital energy in the aura which provides a natural protective sheath around the astral body of the soul.
