One day, Ungan was ill and Dogo asked him a
question: "When you are separated from your
bag-of-bones, where can I meet you again?"
Ungan replied, "Where there is no birth, no
dying."
Dogo said, "Don't say that! Say, `Where there is
not any no-birth and no-dying, and we don't
desire to meet each other again.' "

Now this is something to be understood. We
ordinarily understand two things: the positive and
the negative. Mind moves between the positive
and the negative, for and against. Mind has no
approach, no way to go beyond this polarity, this
duality, this dialectic. And the whole experience of
the buddhas emphasizes only this one thing,
which is beyond duality and dialectics, beyond
yes and beyond no. If you understand this
transcendental experience, then this statement of
Dogo will be immediately understood.
