Scientists have recently ‘discovered’ that trees have a form of consciousness, complex social systems and that they communicate with each other. The Daoists were onto this thousands of years ago. They were mystic / scientists so, unlike western researchers, they could formulate a holistic worldview that explained not only the consciousness of plants (known as shen) but also how humans, plants and animals are connected via chi. I saw the consciousness of trees on my first acid trip, and I still remember how surprised I was when I had a similar experience, without drugs, when I started doing chi-gung. I thought it was a flashback until I read Daoist texts that suggested doing chi practices outside near trees to pick up extra chi. Chalk one up to the tree-huggers!
