Nansen (748-834) was a disciple of Basso and the teacher of Joshu. The following exchange occurred when Joshu was a young man:
Joshu: What is the Way?
Nansen: Ordinary mind is the Way.
Joshu: Shall I seek it?
Nansen: No, if you seek it you cannot find it.
Joshu: Then how shall I know the Way?
Nansen: The way is not a matter of knowing or not knowing. Knowing is delusion; not knowing is confusion.
The true Way is as vast and boundless as outer space. How can you talk about it in terms of right and wrong?
At this Joshu became enlightened.
