Chi is your life force or the energy that sustains you and everything in the universe. It travels through your body along invisible energy channels called meridians.
These meridians act like your circulatory system, but instead of circulating blood throughout the body, they circulate Chi. Since they carry your Chi, which is responsible for your well-being, they are a useful means of detecting imbalances in the organs and body before chronic problems develop.
When the body’s meridians are blocked and Chi is unable to flow freely, becoming disturbed, stagnant, imbalanced or depleted, dis-ease and illness begin to take form. Since all parts of the body are interconnected, if one of the meridians is blocked, the entire body system is affected.
There are 12 major meridians each corresponding to a particular organ (kidneys, liver, spleen, heart, lungs, pericardium, bladder, gall bladder, stomach, small and large intestines, and the triple burner) and each one having a particular characteristic that affects your body on a physiological and emotional level. So when there is an imbalance or blockage in one of the meridians, the symptoms you experience will depend on which meridian is affected.
To complicate things further, the 12 meridians are paired up. That means that there are 6 pairs of meridians, with one of the meridians having Yin energy and the other Yang energy. In addition, each pair belongs to one of five elements: Wood, Fire, Earth, Metal and Water.
These 5 elements are related to the different seasons of the year, colors and emotions.
