It's clearly true for the null koan. > You're half right. There isn't any ambiguity. However, it's clearly NOT try for the null koan. All koans with the buddha nature have grounded pyramids in them (which might be a half-rule you come up with in the process of guessing the rule). The null koan does not. Yes, I'm being a little facetious with my comment about ambiguity. But just because YOU see it as unambiguous and rule one way doesn't mean that someone else can't see it as unambiguous, and rule the other way. Both of you would be convinced that there was no ambiguity. Timothy
