Shoyoroku - Case 79: Chosa Takes a Step

Chosa had a monk ask Master E,
  "How was it when you had not yet seen Nansen?"
E remained silent. The monk asked, 
  "What about after seeing him?"
E said,
  "Nothing special."
The monk returned and told Chosa about this. Chosa said, 
  "The man sits on the top of a hundred-foot pole. He has entered the way,
   but it is not yet genuine. He must take one step from the top of a
   hundred-foot pole. The worlds of the ten directions will be his complete
   body." [1]
The monk said, 
  "How shall one take a step from the top of a hundred-foot pole?"
Sa said, 
  "Mountains of Ro; water of Rei [2]."
The monk said,
  "I don't understand."
Sa said,
  "Four seas and five lakes are all under the imperial reign."

[2]: Ro and Rei are the names of Provinces in the old China.
