Metaphysics is the practice of pure thought.  By means of thought alone we are able to establish that there are four worlds, not one.  The Four Alimonies:  OIOION, ANANON, YLYLCYN, SHEYMN.  It is because of the glimmering of the Genesis Caul - a melted golden protective helm - that we are able to traverse the four worlds.  From the seeming necessity and natural obviousness of SHEYMN we arrive at OIOION, a weeping light yearning to unite with the fallen creation whom she herself has blinded.  This account is a matter of logical necessity, not wild speculation.  If OIOION is not weeping and yearning, then nothing makes sense.
