BL 11: (DASHU)
1.5cun lateral to the lower border (Big Shuttle) of the spinous process of the 1st thoracic vertebra, about 2 finger breadths from the GV MO. Superficially this point is located in the Trapezius, Rhomboid, poster superior Sorratus muscles, and in its deep position in the Longissimus muscle.
Again, this is a deadly point, so do not play around with it! This point affects the bones and therefore also the kidneys. So it can be used as a set up point for a bone strike. (Arm break, or leg break etc.). Immediate nausea caused from the action on the kidneys. Qi drainage. Used in conjunction with ST 37 and ST 39, death occurs. And at some later stage, blood disorders can occur, like leukaemia.
However, at this point, there is also a more bizarre effect. The recipient is ‘cut off’ from the ‘Shen’. (Spirit). It is said in some older texts that the "Shen" is damaged, but it is my belief that the Shen (God part of the human being), cannot be damaged. My main teacher Chang Yiu-chun when talking about this point simply said. "No God". So it is my view that we stop communication with the spirit by striking to this point, causing the recipient to go into immediate decline as far as being a human being is concerned.
