glad it is there
As a fairly new Tai chi practitioner I find this book a bit too much to take in. I barely get the idiom of yin and yang and barely get how it relates to the practice of Tai chi -I will persist. I have some respect for the author/translator from studying several other books by him and have no doubt he knows what he is talking about. And I find the basic sense of it powerful.
I do not particularly like the photographs -it looks to me like too much display and not much substance(??????)Some old photographs of masters or some of the stuff on You tube I find much more informational about the expression of Yin and Yang in the set.
