As the soul prepares or begins to pass out of the body, one of two things may happen. Depending upon the direction and strength of its attachments or desires, it is pulled away from them into unconsciousness, a kind of sleep. Or it recognizes places and persons connected with it, and if knowledge or experience are present, co-operates with the passing and moves out to a higher plane for a blissful sleep. After a while both must awaken to live again.
