“Men are destroyed, and destroy each other, over basic things – money or hatred. On the other hand a really complicated riddle never pushed anyone to violence; either you found the answer or gave up looking. Clouds were riddles too, but dangerously simple ones. If you zoomed in on one part of a cloud and took a photograph, then enlarged the image, you would find that a cloud’s edges seemed like another cloud, and those edges yet another, and so on. Every part of a cloud, in other words, reiterates the whole. Therefore each cloud might be called infinite, because its very surface is composed of other clouds, and those clouds of still other clouds, and so forth. Some learn to lean over the abyss of these brainteasers; others lose their balance and tumble into its eternal blackness.”

“And Lukas would tell them to be good to each other, that there were only so many of them left, and that all the books and all the stars in the universe were pointless with no one to read them, no one to peer through the parting clouds for them.”

“And see those clouds?''Hard to miss''Those are cumulus clouds. Did you know that?''I'm sure I should.'They're the best ones.''How come?'Because they look the way clouds are supposed to look, the way you draw them when you're a kid. Which is nice, you know? ...”

“Look at those clouds," said Jamie, gazing up at the sky. "Look at them." "Yes," said Isabel. "They're very beautiful, aren't they? Clouds are very beautiful and yet so often we fail to appreciate them properly. We should do that. We should look at them and think about how lucky we are to have them." "Look at the shape of the clouds," she said. "What do you see in those beautiful clouds, Jamie?""I see you," he said.”

“To make myself understood and to diminish the distance between us, I called out: “I am an evening cloud too.” They stopped still, evidently taking a good look at me. Then they stretched towards me their fine, transparent, rosy wings. That is how evening clouds greet each other. They had recognized me.”

“On one side, the mass of a mountain. A life I know.On the other, the universe of the clouds, so full of unknown that it seems empty to us. Too much space.”
