When we talk about the Tao, what we are talking about isn't really the Tao, it's just a name. Names aren't reality, they are just names. Everything in the world comes from the nameless. When we learn to think of things as separate from other things, we give them names.

If we look at the world without thinking about our own desires, we can see how everything is connected and part of the same whole. If we only think about what we want for ourselves, we can only see things as separate and disconnected.

Unity and separateness look like two very different ideas, but they really come from the same source. This is called a mystery, because it is hard to understand. It is like something hidden inside something hidden. It is the beginning of all mysteries. http://naturyl.humanists.net/taotext.html
