I can answer that only by ...

I can answer that only by hearsay, returned the Guide, for pain is a secret which he has shared with your race and not with mine; and you would find it as hard to explain suffering to me as I would find it to reveal to you the secrets of the Mountain people. But those who know best say this, that any liberal man would choose the pain of this desire, even for ever, rather than the peace of feeling it no longer; and that though the best thing is to have, the next best is to want, and the worst of all is not to want.

Jill felt like crying when she looked at his face. And Jewel whispered in the King's ear, "By the Lion's Mane, I almost love this young warrior, Calormene though he be. He is worthy of a better god than Tash.

The poison was brewed in these West lands but it has spat itself everywhere by now. However far you went you would find the machines, the crowded cities, the empty thrones, the false writings, the barren beds: men maddened with false promises and soured with true miseries, worshipping the iron works of their own hands, cut off from Earth their Mother and from the Father in Heaven. You might go East so far the East became West and you returned to Britain across the great Ocean, but even so you would not have come out anywhere into the light. The shadow of one dark wing is over all Tellus.
