I think this is it:

http://www.aikiweb.com/language/goldsbury1.html

but I can't be sure because it won't load on the machine I'm using which has no KANJI support (which usually doesn't stop the rest from loading...?) Maybe Jun could help out here, or someone else with better luck with the link. It's a lengthy selection in which Peter discusses several dictionaries' versions of the meaning of budo.

Thanks.
