Your body has 12 rivers of energy that carry the energy of the organs through the body. They are pathways that carry energy into, through, and out of your body. They are bilateral, which means you have them in the same place on both sides. Like a river that rises and falls, the flow of these meridians is ever changing. Along the meridians are hundreds of little electromagnetic reservoirs. These are the "points", the little hot spots, that can be stimulated to release and redistribute energy.
These meridians affect every organ and every physiological system, including the immune, nervous, endocrine, circulatory, respiratory, digestive, skeletal, muscular, and lymphatic systems. Their flow is as important as the flow of blood.
Your body is trying to create balance every day, 24 hours, non-stop. Because of our stressful lives, its pathways need regular maintenance and repair. To "balance" your meridians, means to get them running smoothly, freely, and efficiently.
The meridians are bilateral and some run energy from up our feet to the head (the yin meridians) and some run down from head to feet (the yang meridians). They are as follows:
They all have emotions and psychological components involved in the energy of their organs and pathways. The key to health of body and mind is to keep these pathways moving energy without any blockage of flow. This is why shiatsu, and or yoga, tai chi, and chi kung are important in maintaining flow. These are all vital in preventative medicine. When there is an illness or condition shiatsu can help return the balance of flowing energy to the system.
