The relationship between body, mind, and spirit is that the body reflects what is held in mind, which in turn reflects one's spiritual position. It is necessary to know where all human experience takes place because if we address that level, we will be addressing the most powerful level. If the physical is the consequence of the mental, and the mental is the consequence of the spiritual, then we need to address it in the area called consciousness. Clinically, this is true. People who address the level of consciousness itself may even witness transformation in their bodies with out even having to address the body directly with any medical approach.
