"Psychic means the expression to the material 'observable' world of the latent, or hidden (non-observable) sense of the soul or spirit forces, whether from behind, or in and through the material plane." Cayce (3744-1)
"The study from the human standpoint, of subconscious, subliminal, psychic soul forces, is and should be the great study for the human family – for through self man will understand its Maker, when it understands its relation to its Maker. And it will only understand that through itself. And that understanding is the knowledge as is given here in this state." [Cayce 3744-4)]
To be psychic simply means being aware beyond the usual range of the usual or ordinary physical five senses - a sixth sense of things non-observable. Seeing or knowing with the Mind as opposed to seeing with the five physical senses. Knowing without limitations or constraints of Time and Space. Psychic forces are scalar forces.
"The region of prophetic visions, clairaudient voices, and predictive messages opens up a veritable pit of possible illusions to the mystic. He must beware of the sights and scenes, the self-glorifying revelations which may present themselves to the mind during meditation. He would be better employed chasing such phantasmagorias from the mind rather than seeking to attract them! The mystic must put a stern check upon his imagination if he wishes to pass safely through his apprenticeship. The last word is that the course of meditation may or may not be accompanied by these occult phenomena. Neither does their addition improve the value of the mystic experience nor does their non-existence lessen it. Where they are genuine and authentic communications from the Overself, their value lies rather in personal but transient satisfaction or in immediate but momentary help." (16-12.43) Brunton
