All language is referential. Even in everyday speech the meaning is not in the words themselves, in so much as they are pointers to concepts that (hopefully) exists already in the brains of the people we are conversing with. So when someone is very well aligned, one can convey ideas that go much further than conventionally expressed in the "general" language which is mutually intellible with most speakers of the same language. It is a rare experience though, at least for deep or personal topics.
