That things in their [various] categories are mutually responsive is [something] dark, mysterious, deep and subtle.
Knowledge is not capable of assessing it;
argument is not capable of explaining it. Thus,
when the east wind arrives, win turns clear and overflows [its vessels];
when silkworms secrete fragmented silk, the shang string [of a stringed instrument] snaps.
Something has stimulated them.
When a picture is traced out with the ashes of reeds, the moon’shalo has a [corresponding] gap.
When the leviathan dies, comets appear. Something has moved them.

I don't know how I feel about this. My mother appreciates these ideas. She really likes the "argument is not capable of explaining it" part. I can't say I feel the same haha.
