At the height of Taoism on Laoshan, there were nine palaces, eight temples, and seventy-two nunneries housing more than 1000 religious.
What is Taoism? I Googled it: "In a nutshell, Taoism is the consolidation of a number of concepts and practices that make up the 'Path', or the 'Way' (the Tao) of living. The consolidation of ideas and concepts include basic principles or 'theories' regarding the body, diet, breathing and physical exercises, uses of herbs, philosophical inquiry, and, of course, meditation. All of which the Taoist feels brings a human being into closer alignment with the 'natural order' of life and living--a pathway that humankind appears to have gotten derailed from."
OK, that was nice, but I think a more simplistic but accessible definition is that Taoism is the 'Force' from Star Wars. It is 'the spirit that moves through all things' as taught by Grandfather, a Lipan Apache, to Tom Brown, whose survival and nature-awareness courses I have attended thanks to a recommendation from my Army buddy Dave.
I'd like to point out that Taoism is not a religion. It has nothing to do with religion, either pro or con. You can be a devout follower of any possible religion and also be a Taoist at the same time. There is no conflict between the two.
Going back to Google: "Tao is a force. Tao is everything that is natural, all the laws of physics, the laws of science, the nature of the world. It affects every squirrel, every raccoon, every person. In other words, Tao is the world and the way it works."
