The Holographic Principle
At a highly symbolic level, the holographic principle that "every piece contains the whole" can be seen in the cellular structure of all living bodies. Every cell contains a copy of the master DNA blueprint, with enough information to make an entire human body from scratch. This holographic principle when extended to the human body as a whole and Reflexology in particular may be applied like this. Parts of the body such as the hands, ears, and feet when stimulated affect the body as a whole. In that each of these parts carries the picture of the whole body, and so homeostasis or a dynamic state of balance can be achieved by stimulating the reflexes in any one of these parts.
