Heaven and the clue is prayer
Explanation:
It is evident that the poem's diction using the twilight wind turning a sleeve, means that t<u>he poet is juxtaposing himself against nature and his creator</u>.
The heavy laden metaphor represents a road in the time of twilight which is gruesome.
<u>So, the return back home is less elemental as the home and more ephemeral </u>as the original home where the poet can return and no more burn and toil on the road of earthly life.
the emphasis on prayer (is all my prayer) confirms this.
