a small segment from Dr.John C. Lilly's (the inventor of the sensory deprivation tanks) book, "Tanks for the memories":

  "After 10 years (working) in the tank I formulated a working rule:

 Whatever one believes to be true either is true or becomes true in one's own mind, within limits to be dertermined experientially and experientially. These limits themseves are, in turn, beliefs to be transcended. The limits of one's beliefs set the boundaries for possible experience. So every time you reach a limiting belief it must be examined and gone beyond. For the explorer there are no final true beliefs.

Compulsion is being trapped in a known psychic reality, a dead-end space.
Freedom is in the unknown. If you believe there is an unkown everywhere in you own body, in your relationships with other people, in political institutions, in the universe, then you have maximum freedom. If you can examine old beliefs and realize they are limits to be overcome and can also realize you don't have to have a belief about something you don't yet know anything about, you are free. "
