“Last and crowning torture of all the tortures of that awful place is the eternity of hell. Eternity! O, dread and dire word. Eternity! What mind of man can understand it? And remember, it is an eternity of pain. Even though the pain of hell were not so terrible as they are, yet they would become infinite, as they are destined to last for ever. But while they are everlasting they are at the some times, as you know, intolerably intense, unbearably extensive. To bear even the sting of an insect for all eternity would be a dreadful torment. What must it be, then, to bear the manifold tortures of hell for ever? For ever! For all eternity! Not for a year or for an age but for ever. Try to imagine the awful meaning of this. You have often seen the sand on the seashore. How fine are its tiny grains! And how many of those tiny little grains go to make up the small handful which a child grasps in its play. Now imagine a mountain of that sand, a million miles high, reaching from earth to the farthest heavens, and a million miles broad, extending to remotest space, and a million miles in thickness; and imagine such an enormous mass of countless particles of sand multiplies as often as there are leaves in the forest, drops of water in the mighty ocean, feathers on birds, scales on fish, hairs on animals, atoms in the vast expanse of the air: and imagine that at the end of every million years a little bird came to that mountain and carried away in its beak a tiny grain of that sand. How many million upon millions of centuries would pass before that bird had carried away even a square foot of that mountain, how many eons upon eons of ages before it had carried away all? Yet at the end of that immense stretch of time not even one instant of eternity could be said to have ended. At the end of all those billions and trillions of years eternity would have scarcely begun. And if that mountain rose again after it had been all carried away, and i f the bird came again and carried it all away again grain by grain, and if it sop rose and sank as many times as there are stars in the sky, atoms in the air, drops of water in the sea, leaves on the trees, feathers upon birds, scales upon fish, hairs upon animals, at the end of all those innumerable risings and sinkings of that immeasurably vast mountain not one single instant of eternity could be said to have ended; even then, at the end of such a period, after that eon of time the mere thought of which makes our very brain reel dizzily, eternity would scarcely have begun.”

“a little bird moves a mountain of sand one grain at a time it picks up one grain every million years and when the mountain has been moved the bird puts it all back again and that's how long eternity is and that's a very long time to be dead”

“Just remember: If one bird carried every grain of sand, grain by grain, across the ocean, by the time he got them all on the other side, that would only be the beginning of eternity. ”

“High in the North in a land called Svithjod there is a mountain. It is a hundred miles long and a hundred miles high and once every thousand years a little bird comes to this mountain to sharpen its beak. When the mountain has thus been worn away a single day of eternity will have passed.”

“I mean, d'you know what eternity is? There's this big mountain, see, a mile high, at the end of the universe, and once every thousand years there's this little bird-" -"What little bird?" said Aziraphale suspiciously. -"This little bird I'm talking about. And every thousand years-" -"The same bird every thousand years?" -Crowley hesitated. "Yeah," he said. -"Bloody ancient bird, then." -"Okay. And every thousand years this bird flies-" -"-limps-" -"-flies all the way to this mountain and sharpens its beak-" -"Hold on. You can't do that. Between here and the end of the universe there's loads of-" The angel waved a hand expansively, if a little unsteadily. "Loads of buggerall, dear boy." -"But it gets there anyway," Crowley persevered. -"How?" -"It doesn't matter!" -"It could use a space ship," said the angel.Crowley subsided a bit. "Yeah," he said. "If you like. Anyway, this bird-" -"Only it is the end of the universe we're talking about," said Aziraphale. "So it'd have to be one of those space ships where your descendants are the ones who get out at the other end. You have to tell your descendants, you say, When you get to the Mountain, you've got to-" He hesitated. "What have they got to do?" -"Sharpen its beak on the mountain," said Crowley. "And then it flies back-" -"-in the space ship-" -"And after a thousand years it goes and does it all again," said Crowley quickly.There was a moment of drunken silence. -"Seems a lot of effort just to sharpen a beak," mused Aziraphale. -"Listen," said Crowley urgently, "the point is that when the bird has worn the mountain down to nothing, right, then-"Aziraphale opened his mouth. Crowley just knew he was going to make some point about the relative hardness of birds' beaks and granite mountains, and plunged on quickly. -"-then you still won't have finished watching The Sound of Music."Aziraphale froze. -"And you'll enjoy it," Crowley said relentlessly. "You really will." -"My dear boy-" -"You won't have a choice." -"Listen-" -"Heaven has no taste." -"Now-" -"And not one single sushi restaurant."A look of pain crossed the angel's suddenly very serious face.”
