There are eight extraordinary vessels in the body, only two of them which have acupuncture points, and run along the top of the body, and the bottom of the body, pretty much opposite each other. The other vessels run deep in the body. These vessels called the conception and governing vessels store the polar energies, Yin and Yang. They are accessed through the other meridians in the body, and can be seen to adjust in good flow when dowsing from my perspective, as the other meridians are worked on, and become happy. The energy for the vessels is supplied by the kidneys.
