“If you do, you'll be running an incalculable risk. It will be up to you whether the world begins to live again or stands still forever and a day. Are you really prepared to take that risk?”

“You ask me what you will be there. But what are you here? What are you creatures of Fantastica? Dreams, poetic inventions, characters in a neverending story. Do you think you're real? Well yes, here in your world you are. But when you been through the Nothing, you won't be real anymore. You'll be unrecognizable. And you will be in another world. In that world, you Fantasticans won't be anything like yourselves. You will bring delusion and madness into the human world.”

“No," he said in his deep, rumbling voice. "It means that you must do what you really and truly want. And nothing is more difficult.""What I really and truly want? What do you mean by that?""It's your own deepest secret and you yourself don't know it.""How can I find out?""By going the way of your wishes, from one to another, from first to last. It will take you to what you really and truly want.""That doesn't sound so hard," said Bastian."It is the most dangerous of all journeys.""Why?" Bastian asked. "I'm not afraid.""That isn't it," Grograman rumbled. "It requires the greatest honesty and vigilance, because there's no other journey on which it's so easy to lose yourself forever.”

“You see, Momo... it's like this. Sometimes, when you've a very long street ahead of you, you think how terribly long it is and feel sure you'll never get it swept... And then you hurry. You work faster and faster, and every time you look up there seems to be just as much to sweep as before, and you try even harder…, and you panic, and in the end you're out of breath and have to stop-and still the street stretches away in from of you.”

“You see, Momo,' he [Beppo Roadsweeper] told her one day, 'it's like this. Sometimes, when you've a very long street ahead of you, you think how terribly long it is and feel sure you'll never get it swept.'He gazed silently into space before continuing. 'And then you start to hurry,' he went on. 'You work faster and faster, and every time you look up there seems to be just as much left to sweep as before, and you try even harder, and you panic, and in the end you're out of breath and have to stop - and still the street stretches away in front of you. That's not the way to do it.'He pondered a while. Then he said, 'You must never think of the whole street at once, understand? You must only concentrate on the next step, the next breath, the next stroke of the broom, and the next, and the next. Nothing else.'Again he paused for thought before adding, 'That way you enjoy your work, which is important, because then you make a good job of it. And that's how it ought to be.'There was another long silence. At last he went on, 'And all at once, before you know it, you find you've swept the whole street clean, bit by bit. What's more, you aren't out of breath.' He nodded to himself. 'That's important, too,' he concluded.”

“What will happen when my heart stops beating?" Momo asked.When that moment comes," said the professor, "time will stop for you as well. Or rather, you will retrace your steps through time, through all the days and nights, myths and years of your life, until you go out through the great, round, silver gate you entered by."What will I find on the other side?"The home of the music you've sometimes faintly heard in the distance, but by then you'll be part of it. You yourself will be a note in its mighty harmonies.”
