The accepted proof of satori is a set of literary and rhetorical skills that takes many years to acquire. -- From Chapter 1, an essay by T. Griffith Foulk in The Koan: Texts and Contexts in Zen Buddhism; edited by Steven Heine and Dale S. Wright
I am utterly unequipped to judge the accuracy or even meaning of what is quoted above. But I can say that it felt like a delightfully-sprung trip-wire in my mind.
"Literary and rhetorical skills" sound very much to me like the considerably simpler, "style" ... as in the "style" of shoes or the "style" of music or the "style" of writing. Your "style," my "style," his-her-or-its "style."
And the idea that after all the years of Zen practice, the upshot is simply a matter of style....
That really appeals to me.
No big deal ... mix 'n' match ... it's just my style.
