    Moxa at this point moves yuan qi through the spine, opening the entire Triple Heater mechanism to remove blocks in the channels that prevent back shu and source points points working (Yuen, 2005, The Extraordinary Vessels). Also see Zusanli St-36 and Quchi LI-11 for a similar application when the channels stop working from exhaustion.

    When combined with Waiguan SJ-5 and Yingu Kid-10 this point relates to the Sixth Level of Manifestation of the Soul or the Ajna chakra concerned with the Will to Create endless possibilities. This point pools the Yang, Yingu Kid-10 pools the Yin and Waiguan SJ-5 emanates the resulting mixture outwards via the Yang wei mai and the San jiao as an irrigation system.
    This stage also relates to the formation of the spiritual embryo and attainment of immortality in meditation practice (Yuen, 2005, 3 Spirits & 7 Souls).
