Taoism is complicated.
That's not saying much, but it caps off the quintology of Taoist books I've read recently. There was "Scholar-Warrior," which proved that Taoism was weird; there was Chuang-Tzu, which showed it incomprehensible (to me); The Tao de Ching made it out as lapidary poetry; and You are Already Home," which (mostly) defanged it and stripped it of anything besides New Age bromides (not recognizing its own potential radical subversiveness.)
As the subtitle has it, this is a guide. The bulk of the book focuses on the historical development of Taoism--and history always manages to deconstruct faith. I think that some of the history seems a bit too potted--the Shamanistic roots, for example, the easy divisions between alchemy and other forms of Taoism, the transition from philosophy to religion, which seems the superimposition of Western categories onto ritualistic practices--but what do I know? I learned a lot about how Taoism developed.
Other sections deal with various practices. The metaphysical ones were interesting--though they also had me a bit skeptical--because of how parallel they were to Western traditions, with astrology and alchemy acting as mediators between the divine and the mundane realms. Wong goes over the various physical, mental, meditative, divinatory, and dietary, and breathing techniques used in Taoism, never lingering long, mostly just name-checking them. She does offer further references at the end of each section, which is nice.
She spends a lot of time on the various deities associated with Taoism, their connections to the stars, the emotions, the body parts--which takes Taoism along way from Fritjof Capra's "Tao of Physics," and an even longer way from "Relax, You're Already Home": there's nothing in Wong's account that seems to indicate Taoists thought everything was fine and one needed to do nothing but merge into the flow of the universe. They were doing a lot of work.
As it turns out, the best combination of Taoism and Western ideas may still be in the Tao of (Winnie the) Pooh and the Te of Piglet.
This book doesn't really try to merge East and West, but offers those who know very little about Taoism an introduction to the main ideas and practices--but it is only a glossing introduction, a limning of its boundaries. One could imagine this as a basis for a "Taoism for Dummies" volume--which isn't a criticism. I actually think that's a good series!
So, fine for what it does, though it could have done a bit more.
