When we look at a tree, we do not see the tree for what it really is. We see how it appears to us on the surface, and we dismiss it as being just another form in the Universe. We fail to realize that the tree is connected to the Universe on every level; that all of nature is expressing itself through that single form. There can be no tree without the earth that it grows from, the sun that gives it energy, the water that nourishes its growth, and the millions of fungi and bacteria fertilizing its soil. Looking deeply into anything in nature, we realize that it is connected to the whole. We see that nature is one seamless web, and the notion that things have an existence of their own is merely an illusion.
