I want to put it back together now, this artistic expression that contains religious feeling. I want to investigate: What was the origin? What's happened in the human mind? Can we trace back the moment of the creation of human consciousness? And why did only humans gain consciousness, not other animals? So, evolution? I don't know whether or not I can believe evolution. Maybe we wait for another 100,000 years and then apes get consciousness.

I'm thinking about the end of civilization. We may not keep growing like we are now. There must be an end of civilization. That's what I did as a show at the Palais de Tokyo, the 33 scenarios of how this civilization ends.

I came to California in 1970 and so many people were asking if I was a Buddhist or knew Zen theory, asking if I was enlightened already or not. So I said, "Yes, I am enlightened," and then I studied quickly to catch up.

Humans have changed the landscape so much, but images of the sea could be shared with primordial people. I just project my imagination on to the viewer, even the first human being. I think first and then imagine some scenes. Then I go out and look for them. Or I re-create these images with my camera. I love photography because photography is the most believable medium. Painting can lie, but photography never lies: that is what people used to believe.

Waterlilies always come in Buddhist sculpture. The Buddhas all stand on lotus pedestals, because the lotus is grown from the mud. The mud represents the stained world, a dirty world, but growing from the dirt is such a beautiful, pure thing. This is the way the spirit should be.

Art and religion have the same origin. Art first, or religion first? Maybe consciousness first! Consciousness always comes with religious feeling and artistic identification. It's the same origin.

Fossils work almost the same way as photography as a record of history. The accumulation of time and history becomes a negative of the image. And this negative comes off, and the fossil is the positive side. This is the same as the action of photography.
