The director of intelligence and controller of our individual life. The mind does not function actively and consciously for every requirement of the physical body, as many actions are kinesthetic. Once the consciousness has arranged the muscles, nerves, cells, tissues and their co-ordination necessary to perform its task, it relegates their repetition to the subconscious part of the mind.
It is only when we are confronted with problems or situations outside of ordinary experience that the conscious mind starts to work, because a new theme is involved.
Most of our lives are therefore relegated to subconscious mind operation. The reason for this explanation is that when it comes to trance mediumship, it is easier for a foreign intelligence to take control of the subconscious mind, which is already accustomed to acting on the directions of the conscious mind. This is important as the subconscious is used to taking orders, having tasks assigned and performing them without interruption, save if anything goes wrong.
