Which lines in this excerpt from Samuel Taylor Coleridge's "Kubla Khan" best reflect the theme of chaos and excitement in creation?

But oh! that deep romantic chasm which slanted

{Down the green hill athwart a cedarn cover!

A savage place! as holy and enchanted}

As e'er beneath a waning moon was haunted

{By woman wailing for her demon-lover!}

And from this chasm, with {ceaseless turmoil seething,}

As if this earth in fast thick pants were breathing,

{A mighty fountain momently was forced :}

Amid whose swift half-intermitted burst

Huge fragments vaulted like rebounding hail,

Or chaffy grain beneath the thresher's flail :

And 'mid these dancing rocks at once and ever

{It flung up momently the sacred river.}
