    Ghost Points:
    The first trinity of ghost points, consisting of this point, Shaoshang Lu-11 and Yinbai Sp-1, 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.

    This is the first point of invasion for a possessing force, being located between the nose and mouth, the two main entrances for post-natal influences, its effect on the senses and a distal point for the centre of the chest, Shanzhong Ren-17. At this stage possession is characterised by disruption in the senses and unconscious or psychosomatic reactions to external stimuli. There is a sense something is different or wrong. From here the connection to Yangming enables a route to Taiyin and the following two Ghost points of the first trinity: Shaoshang Lu-11 and Yinbai Sp-1.

    The main force at work here is Wind and so this first trinity is usually treated with bleeding to release the ghost in the exterior (Yuen, 2005 3 Spirits & 7 Souls).


    Ge Hong (4th century) relates a cure for sexual possession of a woman due to having intercourse with a malignant spirit. The symptoms include talking and laughing to herself, depression and delirium.

    The cure involves a ritual and acupuncture. First the master conceals 5 needles in his hair and sets up a vessel full of water with three strips of red cloth placed over the top and a sword laid flat over the top. Next, he calls out the patient's name. She will try to run but must not be allowed to leave. Then, he takes a mouthful of water and sprays it over her, glaring furiously. After repeating this three times he wipes the water from her face and snaps his fingers above her forehead by the hairline and asks her if she wants to be cured. She will not answer until doing this twice, snapping the fingers 7 times each.

    Then insert a needle at this point, Jiache St-6, Shangxing Du-23 and Yintang. Cross examine her thoroughly and she will gradually regain consciousness and the possession will come to an end.
