a koan has the buddha nature if and only if the letters in it go from left to right; in Alphabetic order

BROWNROWNROWN (white) is a counterexample. This was added to my IRC post above while you were writing.

Bouncing on mobius' idea (which may be going completely in the wrong direction) I shall guess:

A koan has the buddha-nature if its first letter is the same as or alphabetically earlier than each of its other letters.

A koan has the buddha-nature if its first letter is the same as or alphabetically earlier than each of its other letters.

This is not correct. There is one existing disproving koan: BROWNBROWN, marked black, which would be white according to this guess.

Tea and charcoal is about the only thing that colored appropriately here. <_<

Ok then, I guess that a koan has the buddha-nature if its first letter is alphabetically earlier than each of its other letters.  http://www.lemmingsforums.com/Smileys/lemmings/tongue.gif" alt=":P" title="Tongue" class="smiley" />

DOH! I actually thought of this but for some reason immediately thought; "no, that can't be it"  http://www.lemmingsforums.com/Smileys/lemmings/XD.gif" alt=":XD:" title="XD" class="smiley" />

good job, and good rule. Simple yet stumped everyone for a while

In this round, BUDDHA has the buddha-nature
and NATURE does not have the buddha-nature.
