The Gateless Gate, by Ekai, called Mu-mon, tr. Nyogen Senzaki and Paul Reps  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.
