The Gateless Gate, by Ekai, called Mu-mon, tr. Nyogen Senzaki and Paul Reps [1934]
Joshu asked Nansen: "What is the path?"
Nansen said: "Everyday life is the path."
Joshu asked: "Can it be studied?"
Nansen said: "If you try to study, you will be far away from it."
Joshu asked: "If I do not study, how can I know it is the path?"
Nansen said: "The path does not belong to the perception world, neither does it belong to the nonperception world. Cognition is a delusion and noncognition is senseless. If you want to reach the true path beyond doubt, place yourself in the same freedom as sky. You name it neither good nor not-good."
At these words Joshu was enlightened.
Mumon's comment: Nansen could melt Joshu's frozen doubts at once when Joshu asked his questions. I doubt though if Joshu reached the point that Nansen did. He needed thirty more years of study.
