I recently read a book, The Complete Book of Zen, in which the author stresses the fact that practicing kungfu and chi kung is essential to cultivating your Zen experience and eventually realizing your cosmic reality. While I could see the benefits, I have not heard this before, and have to wonder is there actual merit to this claim, or is it simply a skewed viewpoint, given that he is in fact a grandmaster of both Shaolin Kungfu and Chi Kung.
Any thoughts?
