Astral plane
The repository of the collective thought/feeling patterns, conscious and unconscious, of mankind. The pristine purpose of this band, or frequency, is for the amplification of the pure thoughts and feelings of God in man. Instead it has been polluted with the impure records (vibrations) of the race memory multiplied ad infinitum by an evolution caught in the riptides and repetitive cycles of its own negativity.
