I am the author of this book. I feel this is a very good book, however the publishers made a serious error in editing when they did this book, and did not send galley proofs to me before publication. Warning: the meridian charts are not correct. The POINTS on each chart, eg. key points on the stomach meridian, ARE CORRECT, but the meridian lines showing the paths of the meridians are not correct. The reader should refer to the text, and, perhaps, buy a seperate set of charts. P. S. people who have used this book tell me it is very helpful. Helen Saul
