Astral Projection is a natural psychic function which is not reliant on the conscious awareness of the person concerned. Day after day usually once within every twenty-four hours, an individual spirit is displaced from its physical body but this is usually done while it is in a condition of stupor, where it is not aware that it was separated. It then becomes conscious again as a physical body and gets busy to restart its activities.
Astral projection is really the observation of that displaced psyche. Information of how to become conscious of this is divulged in this paper.
