Concerning The Planes of Existence (Excerpt from Chapter 6)
Variation in the vibrational characteristics of the subatomic strata of a given realm (known collectively as its waveform) is the reason beings on one plane of existence do not perceive beings or environments on another plane even though they may occupy the same region of spacetime.
Through acts of sorcery or by technological means it is possible for beings to alter their waveform and attune it to the definitive waveform of another plane of existence. By doing this they can achieve an array of results such as sending and receiving thoughts between planes; seeing, hearing and feeling things on other planes; and transferring the entirety of their physical being from one plane to another.
It is important to note that extra-planar travel, or transfer in any degree of phase variation from one plane to another, is made possible by way of conscious or technological alteration of the waveform of the physical body, and that this should not be confused with the practice of extra-planar projection.
Extra-planar projection is the phenomenon by which a being sends a duplicate of the envelope that is mind containing a body constructed from a portion of its aetheric energy to one of the proximal planes (most commonly the astral or dream realms). While the waveform of the projected aetheric body is attuned to the waveform of the destination realm, the physical body proper and the majority of that body’s aetheric energy remain (in an unconscious or meditative state) on the plane the being has projected its consciousness from.
As a rule, extra-planar travel is not possible within the realm of Sanctuary because it requires access of the consciousness to the null-point where probability can be manipulated. This being said, there is one exception. The Martian gatestreams, which were products of the lost Martian alchemy, do function within the sphere of Sanctuary.
Planar projection on the other hand is a common occurrence on Sanctuary. All humans project their consciousnesses to the dream realm during the sleeping state and many humans are capable of projecting to the astral plane when in a meditative state.
