I thought it was about not following any set practices and about following the simple guidelines mentioned in the agile manifesto (http://agilemanifesto.org/). No matter what process you follow to achieve it.
Does it, though? I dunno. I didn't read it. When I see a book with words like 'ninja' and 'samurai' and it doesn't involve martial arts, I generally just ignore it because it seems childish.
