The Ruba'iyat and Existentialism

I think this stanza from The Ruba'iyat captures much of Existentialism's notion of "absurdity":

If only there were occasion for repose,
If only this long road had an end,
And in the track of a hundred thousand years, out of the heart of dust
Hope sprang again, like greenness.

I envision the last line throwing the others into confusion.
