    Ghost Points:
    The first trinity of ghost points, consisting of this point, Yinbai Sp-1 and Renzhong Du-26, represent the initial stages of being taken over. Being at the peripheries of the body they are aimed at expelling the influence before it takes hold.

    As the second point in the first trinity, the name of this point, Guixin, Ghost Trust, reflects that the ghost gains your trust and you stop noticing the change as different or usual. Its other name, Guiyan, Ghost Talk, refers to the main symptom of this stage being changes in the throat and voice, a rattling or crackling and continual need to clear or cough (Phlegm). Other symptoms include susceptibility to changes in the exterior, especially Yang factors such as wind, heat and light, as you take on the a Yin nature of the Ghost.

    This point should be needled rather than treated with moxa. The needle technique is usually Zheng Dong, to "rattle" the needle as if to shake someone into waking up (Yuen, 2005, 3 Spirits & 7 Souls).
