dk75 and I are on the same page for sure. You know chi has been documented as working and being very real. Thermal imaging cameras have been used to document any changes in the body temperature of someone performing chikong(chi exercises). The practitioner was asked to direct the chi into specific body parts and the thermal imagining camera picked up the heat transfer into these parts with astonish results. The results from the camera correlated perfectly with the asigned tasks.
Chi comes from a place in the lower abdomen called Dantian, located between the kidneys. Practioners in the higher art of Chikong, circulate chi around the body from the dantian, using specialised breathing, visualization and sensory techniques. The higher art can be very dangerous if not used by an expert, as the chi becomes too strong and trapped if not used properly and replaced back into the dantain after use. Chi must be able to flow and not become trapped. The lower art of chikong is less powerful and completely safe, as it does not evoke the complete powers in the dantian, which can be too much for non experts to control. Lower chikong is used for increasing vitality and health throughout the body. Higher chikong is used for both this and to increase the power of the body in martial art. Making it possible for iron bars to be broken over the skull, with no harm to the practitioner. I have witnessed it myself. 2 inch thick wooden staves, smashed across the arm and breaking the stave in 2 with no ill effect or even marks on the practioner being hit. The practioner needs to push the chi into the required place first, then after being used, replace the chi back into the dantian.
There is one thing stronger than all the armies in the world: and that is an idea whose time has come.
