94- The Third Force
Therefore, we must consider the third force. That third force can be neither the physical body nor the spirit. It is what we call the perispirit. It is with the body during natural sleep, self-hypnosis, or unconsciousness and acts as a mediator between the spirit and body.
Yes, my dear brother, the astral body's existence is proven with solid reasoning, and we are forced to believe its existence. Also, we now understand that it remains inside the body during the state of sleep and unconsciousness.
