By Becoming Conscious of the Light in the Head, One Can Also Learn to See the Masters and Adepts.
"Not only does this level of consciousness enable a person to recognize an Adept on this plane, but to see them on other planes through clairvoyant vision. It seems paradoxical that before one can recognize an Adept, one must lift the consciousness to the point where the truth can be perceived. There are an infinite number of dimensions existing here in space, filled with all manner of embodied souls. Through clairvoyant vision it is possible to part the curtain and attune to the desired level. Negative people contact the dregs of the astral as their perceptions quicken, restless people contact others like themselves, who have gone on into the astral but who are not any more illumined. Pure minded individuals contact illumined beings, on this and other planes. This is possible when the barrier of time and space ceases to exist. Usually we will contact an Adept in deep meditation, when we tune out this world, although it is possible to see through the veil into their realm of activity while being fully aware of this world. Since we are sensitized by contacting the light within, we become aware of the subtle worlds already existing about us.” - Roy Eugene Davis, This Is Reality
