" Talk about claustrophobia! ... So in the end I had an idea. When I couldn’t stand it any longer, I would close my eyes and think of the herds of elephants at liberty, running freely across Africa, hundreds and hundreds of magnificent animals that nothing can resist— no cement wall, no barbed wire, nothing: they rush forward over the great open spaces and smash everything in their way, and nothing can stop them. That s liberty, I tell you! So when you begin to suffer from claustrophobia, or the barbed wire fences, the reinforced concrete, the absolute materialism, just imagine this: herds of elephants charging across the wide open spaces of Africa. Follow them with your eyes closed, keep their image inside you, and you’ll see, you’ll feel better and happier, and stronger . . . "
