“The grand trick of those sorcerers of ancient times was to burden the flyers’ mind with discipline. Sorcerers found out that if they taxed the flyers’ mind with inner silence, the foreign installation would flee, and give any one of the practitioners involved in this maneuver the total certainty of the mind’s foreign origin. [It] comes back, I assure you, but not as strong; and a process begins in which the fleeing of the flyers’ mind becomes routine until one day it flees permanently.”

~Don Juan Matus, “The Active Side of Infinity”, by Carlos Castenada
