the name is a little mis-       
   giving, because of course there is   
 no  real geometry in  the caves. you may 
 feel as  if you are  venturing into some 
 vast  structure,  but  you  are  in fact 
 leaving any such thing at  the entrance. 
     leaving physical tethers behind,     
  submitting to an inescapable darkness,  
 the  world  around you becomes more of a 
 manifestation   of   your  mind,   or  a 
 collective  mind,  with  a shape  and  a 
          direction and a taste.          
  inescapeable darkness, because if you   
 bring   a  candle  or  mount  electrical 
 lights,   the   walls  only  serves   as 
 markers  to   where  the   tiny  spatial 
 existence ends  and the darkness beneath 
                it begins.                
 like  an  inverted mandelbrot, the  real 
 cave  is actually  not  the pockets, but 
 the  black  around  them.  keep  that in 
 the  moisture that  permeates  any  cave 
 worth it's  name...  it's the  water the 
 world  rose  from. it's  the  water  you 
        drown in, in your dreams.         
 the only  sounds in the  cave  are those 
 that  you make  yourselves. they may  be 
 distorted  by the  stone  structure, and 
 amplified by your  mind.  try  not to be 
 alarmed,  try  to  remember  the persons 
 and  objects around  you,  and  you  can 
 discern   a   mirage  from   a   friend.
