I have now studied this book in part or in whole at least six times. I have bumped my rating up to 5 stars because every time I reread it, I find more in depth information or points of interest that take me deeper and deeper in to my tai chi practice.
IF you just read it through, like a novel, you will likely be a little bored and will say, I've read it all before.
But, if you take each little bit of data and try to apply it to your own tai chi practice, you will discover valuable insights and causes for deep reflection. This is a book that deserves to stand with the best of tai chi learning.
Do not discard it as something you have read before by others. The pool is deeper than it looks upon first inspection.
