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.
