Modern versions of these charts are still widely used today, in many types of alternative medicine and body work, i.e. acupuncture and reflexology. Primary energy centres are attached to major internal organs, glands, nerve ganglia and the spinal cord. Secondary and minor energy centres are attached to joints, glands and nerve clusters, throughout the body. There are storage centres, communication centres, and centres designed to absorb energy from other energy sources around us. Some of these energy sources are very subtle, but all are necessary for us to live a balanced life.
Every energy centre has important individual functions, in the energy body.
It also works in conjunction with all the other major and minor centres. Each centre is an individual, but integral part of the energy body. The energy body is extremely complex. It is, in a way, similar to an electronic device. A single energy centre, is very much like a single electronic component.
