The Governing vessel point along with the bladder points, calls the external dragons to heal with the cleansing energy of water. The seven external dragons appear and chase out the invasive energies. The water comes and runs through on the etheric level. It allows the water element to harmonise in your outer bodies and physical body. The Shen of your outer bodies will be stabilised. The light of the patient is now brought back.
