He Wishes For The Cloths Of Heaven by W.B. Yeats. Mahler - Symphony No.3 - 6th Movement (excerpt).

Had I the heavens' embroidered cloths

Enwrought with golden and silver light

The blue and the dim and the dark cloths of night

And light and the half-light

I would spread the cloths under your feet

But I, being poor, have only my dreams

I have spread my dreams under your feet

Tread softly,because you tread on my dreams.
