Ten fields of energy, three being primary, located along the Central Channel of the body. The Lower Dantian, also known as the Golden Stove and the Lower Cinnabar Field, the Dan Jun (Korean), the Hara (Japanese), is central to the restoration and maintenance of the Three Treasures. One can breathe into this center (located internally a couple inches below the navel) with focused intent to invigorate this center with Qi. This breathing is fundamental to Taoist meditation and Qigong.
