I have many names, and none of them matter. … Names are not important ... To speak is to name names, but to speak is not important. A thing happens once that has never happened before. Seeing it, a man looks upon reality. He cannot tell others what he has seen. Others wish to know, however, so they question him saying, "What is it like, this thing you have seen?" So he tries to tell them. Perhaps he has seen the very first fire in the world. He tells them, "It is red, like a poppy, but through it dance other colors. It has no form, like water, flowing everywhere. It is warm, like the sun of summer, only warmer. It exists for a time upon a piece of wood, and then the wood is gone, as though it were eaten, leaving behind that which is black and can be sifted like sand. When the wood is gone, it too is gone." Therefore, the hearers must think reality is like a poppy, like water, like the sun, like that which eats and excretes. They think it is like to anything that they are told it is like by the man who has known it. But they have not looked upon fire. They cannot really know it. They can only know of it. But fire comes again into the world, many times.
