"the very first time they present an apparently subjectless sentence, all japanese textbooks should have large warnings printed in red:

you are now entering the twilight zone

it is here, more than anywhere else, that the language suddenly begins to melt into that amorphous mass of ceremonial tea and incense and zen and haiku, where distinctions between self and other, i and thou, subject and object, disappear in a blinding flash of satori."
