According to another member's post on the DAN TIEM (see below), I feel more confused than ever: if the brain is the UPPER Dan Tiem, the belly is the MIDDLE / 'true' Dan Tiem, and the Lower Heater of the body is the LOWER Dan Tiem -- WHERE does that leave the Upper Heater of the body (everything above the belly to under the head)? And what does this have to do with the circulation of Chi throughout the body (which produces DYNAMIC MOVEMENT). Quote: Without turning this into a major thesis, it is due to the physical attributes of the intestinal tract and it's centre of gravity, it's ability to act like a huge conductive battery, that this point is the logical heart of the Dan Tien; it is a giant battery for bioelectricity. So we see that with the triple heater Qigong that we do ( if you do this ) you are actually developing and storing Qi. Cultivating it in the lower, storing it in the middle physical Dan Tien, and then circulating it via the upper Dan Tien . The brain is the upper Dan Tien, the middle Dan Tien is the true physical Dan Tien and the lower Dan Tien is the Dan Tien of mind or the lower heater.
