De Daumier-Smith's Experience

In the handout, "What is The Sound of One Hand Clapping?", the last paragraph says that "the meaning of a koan can only be demonstrated in a live experience..."  In "De Daumier-Smith's Blue Period", the narrator sees a girl in a shop changing the truss on a wooden dummy.  The girl falls on her bottom and the narrator says, "It was just then that I had my Experience" (250).  The narrator is a (supposed) student of Buddhism, which proves that this "Experience" is when he comes to an understanding of a koan.  I was wondering if the koan in the beginning of Nine Stories (what is the sound of one hand clapping) is the same koan that Jean De Daumier-Smith now understands, and if the narrator's statement of "Everybody is a nun" (251) is his own, new koan for the readers to have to experience.

P.S. Does this make any sense?  (Unlike Jean De Daumier-Smith, I unfortunately can't even attempt to explain my thoughts in any other language as I'm accustomed to writing most things in English, and not French.)
