(you need this, of course as per the obvious recent discussion re
ambiguity; I'd probably default to mastering it with single-ray koans
= true, myself, but that's my bias).
Needed clarification: are overlapping rays considered the same ray or
different rays? This is, clearly, really important -- with it, a true
koan can have any number of pyramids > 1, without it, it can only have
2 or three pyramids.
