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.
