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. Scientific discoveries in the world of cellular biology, have demonstrated that every cell contains a copy of the master DNA blueprint, with enough information to make an entire human body from scratch. The fact that every cell within the human body contains the information to create an entire duplicate body mirrors the holographic principle whereby every piece contains the information of the whole.
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.
