I just read this yesterday in the New Yorker piece about JD.[1]
When he was a teen-ager, Dorsey told me, he read a book about tea
ceremonies and was impressed by the Japanese precept of wabi-sabi,
which holds that the greatest beauty comes from organization with a
dash of disorder. “The monks rake up leaves, then they sprinkle a few
leaves back,” he explained.
