Scientology Axiom 8
Axiom 8: The apparency of time is the change of position of particles in space
Here is how we perceive time and how we perceive the fact that something is persisting (continuing to exist): Particles change their position. In fact this is how we measure time by the rhythmical or cyclical change of position of particles in space: The sun moving through the sky, the pendulum swinging back-and-forth, the hands of the clock ticking the hours away are the means we use to perceive time and the continuation of existence.
Have you ever been somewhere with little or no motion? Did it seem like there was no time, like every instant was an eternity? This is actually used as a form of punishment and torture: "solitary confinement", "sensory depravation". Although the torturer thinks it's only the lack of sensation that is the torture, the fact of no motion so that every instant seems like an eternity makes the lack of sensation much worse. To the victim it seems to be lasting days whereas to the rest of the world it is only a few hours. If the victim could cause motion, even if it were only in his own mind, then the torture would be less effective.
