Luke closed his eyes, relaxed, and began to free his mind, began to control theimages. At last there was something, not clear at first, but something white,amorphous. Gradually the image cleared. It seemed to be that of a city, a city thatperhaps floated in a billowing white sea. "I see a city in the clouds," he finally said. "Bespin," Yoda identified it. "I see it, too. Friends you have there, heh?Concentrate and see them you will." Luke's concentration intensified. And the city in the clouds became clearer.As he concentrated he was able to see forms, familiar forms of people he knew. "I see them!" Luke exclaimed, his eyes still shut. Then a sudden agony, ofbody and spirit, took hold of him. "They're in pain. They're suffering." "It is the future you see," the voice of Yoda explained. The future, Luke thought. Then the pain he had felt had not yet been inflictedon his friends. So perhaps the future was not unchangeable. "Will they die?" he asked his master.
