Caking the dark walls of your psyche are scads upon legions of parasitic neuro-psychic memetic structures, known as concepts, ideas, paradiegms...

Morality is the best of all devices for leading mankind by the nose:
Friedrich Nietzsche, The Antichrist

These halls of Evil are abstract representations of concrete existence. As such they should not be taken too lightly... nor too seriously. The ability of the unmanifest to be-come via imagination fueled by emotion and guided by intellect is potentially risky. Therefore caution should be taken when dealing with such complex cosmogenies of an panmoral nature or societal conflicts could ensue. (as long as you dont admit to being insane you'll probably be alright). The sounds, images, and abstractions you find in these halls are quite varied in appearance, style and content, though they all have a central underlying theme. If you think you know what that is you are already endangering your psyche.
