Query: Very useful for the seeker, but . . .

I found this book very nicely organized and the Self Test very useful indeed. However, I wonder why there is not even a mention of Taoism, the ancient spiritual path of China, and the basis of the increasingly popular form of "soft" martial art, Tai Chi Chuan. Some may argue that Taoism is more a philosophy, not a "religion" per se, but in some sense neither is Buddhism. Maybe the third edition could correct this omission? Otherwise, A-plus!
