Your Pituitary Gland is supposed to be the location of your 3rd Eye or the place to experience Extrasensory Information.
What Art said about his ability to dowse when it didn't work (?) and then the returning ability after it repaired itself and the pain he experienced, confirms my belief that our varying ability is due to how active our Pituitary Gland is.
This varies from person to person and can be Developed to be more sensitive.
The BELIEF in ALL the Various things each of practitioners experiences is THEIR Belief and have Nothing to do with the actual response data.
This is what Ingo Swann came to believe from all his research. There is a POOL/Cosmic Consciousness that Records ALL HUMAN Experience from the Past, Present, and Future and this is what we are accessing when we Meditate/Dowse/??. There is no TIME as we know it there because there is no Sun and Revolution around it to Make/Record Time By.
