Shoyoroku - Case 89: Tozan's "Place of No Grass"

Tozan instructed the assembly and said,
  "At the beginning of autumn and the end of summer, you, brothers, are
   departing east and west. But you should go directly to the place of no
   grass over ten thousand miles."
And again he said,
  "How will you go to the place of no grass over ten thousand miles?"
Sekiso said,
  "When you go out of the gate, there is grass!"
Taiyo said,
  "I would say: Even if you don't go out of the gate, grass is abundant
   everywhere."
