"I was always interested in Egyptian mummies […] but later on, during the Vietnam War, when I saw all these bodies in plastic bags […] then I thought of that whole thing too. […] The string does have to do with imprisonment. […] I am very concerned about the political prisoners all over the world, and of course it had to do with my own past experiences, where I was not tied up, but it does not mean literally, physically tied up. [Y]ou can be in prison without being in a locked room. You are imprisoned by your own fears, inhibitions, phobias."
