I did put "zen state" in quotes by the way, since it was merely an analogy.See, that's an example of the fluff not matching the mechanics. Why would a Zen state end if you don't attack something? Why would a zen state grant a bonus to strength saves and strength checks? Why would it only apply to weapons using strength? Zen is typically associated with speed and accuracy, not strength. That fluff creates a disconnect with the mechanics in question.
