I think that the Tao of Pooh and Te of Piglet are great introductions for folks to Daoism. A lot of core philosophical concepts such as the uncarved block and effortless action are explored in the books in a manner which most folks can relate to. They also serve as a jumping off point into other books like the Daodejing and Chuangtzu.
As for religious Taoism, my current view is that in America there is a lot of misunderstanding around what this is. One way of looking at religious Daoism is that it is the combination of the philosophy of the Daodejing and Chuangtzu and other texts combined with the animistic worldview of ancient Chinese shamans to create powerful vibrant system of ritual and ceremony that is done to help all beings be one with the Dao. It is very, very similar to Shinto in this way and more and more there are starting to be scholarly works that compare the two as parallel traditons.
As for what this means for rewilding in America in 2008, I’m not entirely sure. Part of the reason I started this thread.
