Haven't you read how in the old days, Master
Tzu Hu said,

    The Patriarch's coming from the West only
    means that winter is cold and summer is
    hot, night is dark and day is light.

It's just that you vainly set up meaning where
there is no meaning, create concern where there
is no concern, impose "inside" and "outside"
where there is no inside or outside, and talk
endlessly of this and that, where nothing exists...
