I am writing this from the perspective of a math specialist in the United states. Cultural and linguistic differences...
I describe meridians to children and their parents as rivers of energy the flow through the body. They can also be described as highways of energy. Along these highways there are points, like rest areas, that, when activated, can affect different systems or emotions. For example, the heart 7 point is related to emotional issues especially excessive anxiety and worry. Stimulating a point is as easy as gently massaging, using a laser light, or using a specialized acupatch that reflects your body’s infrared light back into that point.
There are 14 meridians that run on that run basically along the surface of the body and 8 extraordinary meridians that run in the interior, which are not generally known or talked about.
12 of the meridians are bilateral, meaning that there is one on each side of the body and one runs up the center in the front and one up the center in the back.
Each meridian corresponds with different organs. When the energy is not flowing properly, there can be over energy or under energy in a specific meridian, thus affecting those organs. The heart meridian, for example, regulates and influences the heart, circulatory system, sweat, speech, and even mental activity, memory and sleep.
Each tooth in the human mouth is related by a meridian to an organ in the body. When an organ or system becomes diseased or infected, the associated tooth most likely will express some type of symptom as well. For example, the back molars are the ones related to the heart. Therefore, problems in a tooth, could be a sign of a deeper issue.
There are a couple of ways to balance out the meridians. One is to simply hold the endpoints for approximately 30 seconds. You also can sweep it in the appropriate direction by taking your hand and tracing it from endpoint to endpoint. Some meridians run up and some run down. Running it in the opposite direction would bring more energy to the meridian and running it in the correct direction would get rid of excess energy (though you would never want to run the heart energy toward the heart).
Each meridian influences another. Think of being on a highway and if there is a jam on a highway that branches off the one you are on, then it can back up your highway too. Therefore when working to balance one meridian, you have to check them all.
Over the next few weeks I am going to highlight a specific meridian along with a key point or two on each.
