What's in a name?

A name is imposed on what is thought to be a thing or a state and this divides it from other things and other states. But when you pursue what lies behind the name, you find a greater and greater subtlety that has no divisions. Atoms of dust are not really atoms of dust but are merely called that. In the same way, a world is not a world but is merely called that.
