Despair not! For though dark they stand,
All woods there be must end at last,
And see the open sun go past:
The setting sun, the rising sun,
The day's end, or the day begun.
For east or west all woods must fail.
--J.R.R. Tolkien
The Fellowship of the Ring
If anyone has the book at hand, this sounds like it's missing a line or so (I found it online), but I might be just misremembering how it sounds.
