Spirits in Bondage

So piteously the lonely soul of man
Shudders before this universal plan,
So grievous is the burden and the pain,
So heavy weighs the long, material chain
From cause to cause, too merciless for hate,
The nightmare march of unrelenting fate,
I think that he must die thereof unless
Ever and again across the dreariness
There came a sudden glimpse of spirit faces,
A fragrant breath to tell of flowery places
And wider oceans, breaking on the shore
From which the hearts of men are always sore.

(C.S. Lewis - XV. Dungeon Gates)
