" You must try to divorce your actions from conscious control. Try not to focus on anything concrete, visually or mentally. You must let your mind drift, drift; only then you can use the force. You have to enter to a state in which you act on what you sense, not on what you think beforehand. You must cease cognition, relax, stop thinking... let yourself drift... free... free... "
― George Lucas , Star Wars: A New Hope (Star Wars: Novelizations, #4)
