None needed!
It was not my intent to 'correct' anyone, although I see that my post might have implied such. Let me say right out I was the owner of just such a book, and there is, apparently, an order to the koans, but they are an experiential thing, not an intellectual thing.
Oooh - unless your response was, in itself, a koan?
(Not being flippant, this is a very imprecise medium of communication, it lacks all subtlety, but my point being that often a simple response can have a koanic effect.)
My own koan:
I watched a TV show once in which a physicist explained that all the heavy elements (carbon, etc) can only be manufactured in one place in the universe - in the heart of a star. It takes a nuclear furnace of stellar magnitude to produce carbon, and every atom of carbon in our bodies came from the heart of a star. "We are indeed," he said flippantly, "stardust."
Now I knew this. I learnt this at school, along with how many HB pencils I can be made into, and really useful stuff like that. So nothing new, and yet, it was, it was, as I sat there on the sofa one Saturday evening, an epiphany.
Can't explain it. Can't convey it. Can't reproduce the moment or the feeling, but it was, as they say, 'something else.'
So that atom, created in a star, spat out into the infinite cosmos, journeyed for immeasurable millenia across unimaginable distances, saw indescribable things, the births and deaths of galaxies, knew heat and light, cold and darkness in extremis ... and ended up ... here, in me ... and not just that one, but millions of 'em, and from all over!
Oh, what a story I could tell, if only I knew ...

(of course, it could also be strictly local. Made in the sun, popped out, and eleven odd minutes later arrived here ... might not even be a nice person...)
