The conscious mind is a maelstrom of fleeting thoughts, images, sensations, feelings, conflicting desires, and doubts; barely able to confine its attention to a single clear objective for a microsecond before secondary thoughts begin to adulterate it and provoke yet further trains of mental discourse. If you do not believe this, then attempt to confine your conscious attention to the dot at the end of this sentence without involving yourself in any other form of thinking, including thinking about the dot.
Careful observation will confirm that virtually all spontaneous parapsychological events occur through some form of sleight of mind. It is invariably something hovering just below the threshold of awareness that initiated an unusual event or gave one a curious half sensed feeling that something was about to happen just before it did. The magician seeks to exploid this effect deliberately, but in doing so he must avoid doing it deliberately as it were. Conscious lust of result destroys magical effect, so trickery must be employed to annul it and to activate the subconscious.
