The Universal life energy or Qi, present in every living creature circulates throughout the body along the pathway of meridians. Qi is generated from the vabration of the five elements. As long as this energy flows freely throughout the meridians, body is healthy but when there is flow of pathogenic energy that causes blockage in the body, the system is disrupted, pain and illness occur. Acupuncture needles when inserted at the acupoints, it helps restore normal functions and free up the blockage from the pathogenic Qi. (Meridians are like the battery of the computer and acupoints as their charger)
