The idea underlying Shiatsu is that energy flows in the body through a series of pathways called meridians. At times, for one reason or another, the energy flow gets out of balance and stops moving smoothly. A dis-ease then appears. It can be just a vague feeling of discomfort or a diagnosed illness.
The aim of a Shiatsu treatment is to rebalance the flow of energy so that it flows smoothly again. As the flow of Ki in the body improves, so does the condition. Shiatsu is a therapy that works on the individual as a complete being. It works both on the physical as well as on the psychological level.
