Well, Eliot said it was the state of his mind--or words to that effect. He said it more than once.  If we dismiss his testimony (as one of those literary critics who do not know what is the true way to read?), we may be left with a poem largely "underpinned" rather that simply edited by Ezra Pound

Granting that "underpin" is not a very exact word here, the "state of mind" in which the pearl of the poem is produced is not the process that produces the poem. What's central to the poem as poem is that process.

What underpins TWL?

The poet's nervous breakdown reflecting the nervous breakdown of Europe into
the Insanity of 1914.
Eliot, in a private paper, written in his sixties, confessed: "I came to
persuade myself that I was in love with Vivienne simply because I wanted to
burn my boats and commit myself to staying in England. And she persuaded
herself (also under the influence of Pound) that she would save the poet by
keeping him in England. To her, the marriage brought no happiness. To me, it
brought the state of mind out of which came The Waste Land."
