adj. Having or carrying the characteristics of the astral plane.
n. A frequency of time and space beyond the physical yet below the mental, corresponding with the emotional body of man and the collective unconscious of the race.
Because the astral plane has been muddied by impure human thought and feeling, the term “astral” is also used in a negative context to refer to that which is impure or “psychic.”
