It is the accumulated recordings of thoughts, conclusions, decisions, observations and perceptions of a person throughout his entire existence. In Scientology it has been discovered that the mind is a communication and control system between a thetan and his environment. The most obvious portion of the mind is recognizable by anyone not in serious condition. This is the mental image picture. Various phenomena connect themselves with this entity called the mind.
Some people closing their eyes see only blackness, some people see pictures.
The mind is a communication and control system between a thetan and his environment. The mind is not a brain. The thetan receives, by the communication system called the mind, various impressions, including direct views of the physical universe. In addition to this he receives impressions from past activities and, most important, he himself conceives things about the past and future which are independent of immediately present stimuli. A person who has taken drugs, in addition to the physical factors involved, retains mental image pictures of those drugs and their effects.
