Namkai Norbu, p. 68 The Crystal and the Way of Light

  This is the open secret, which all can discover

       for themselves.  We live our lives, as it were 
       "inside out," projecting the existence of an "I"
       as separate from an external world which we try 
       to manipulate to gain satisfaction.  But as long
       as one remains in the dualistic state, one's 
       experience has always underlying it a sense of 
       loss, of fear, of anxiety, and dissatisfaction.
       When, on the other hand, one goes beyond the 
       dualistic level, anything is possible.
