The rest of the crowd were still in the dark, so to speak, so the Buddha delivered a sermon--the great Flower Wreath Sutra (Avatamsaka Sutra)--to explain what he meant, which was this:

There is nothing to say about life. It has no meaning. You make meaning. If you want a meaning in your life, find a meaning and bring it into your life, but life won't give you a meaning. Meaning is a concept. It is a notion of an end toward which you are going. The point of Buddhism is this is it.

The Buddha is called tathagata, "the one who has come, thus"; the flower is the tathagata that has come thus. The Buddha is often shown just looking at the flower. That flower is the world. That flower is a flower. That flower is what I am looking at now. This has been made to serve an end but that is not the essence of the mystery of this thing. The essence of the mystery is its very being, which has a ring around it of cosmic ocean, you might say, beyond which you cannot look.

Buddhism is the illumination to the fact, the realization of the fact that this is it. You are it and it is nothing. It is a very difficult thing to tell anyone about because the words themselves suggest that there is a meaning here, but the thing is just to get it, and that is why you can't communicate or teach Buddhism: you can only bring a person up to it.
