Shoyoroku - Case 83: Dogo's Nursing the Ill

Isan asked Dogo,
  "Where have you come from?"
Dogo said,
  "I come from nursing the ill."
Isan said,
  "How many people are ill?"
Dogo said,
  "There are some ill, and some not ill."
Isan said,
  "The one who is not ill isn't that you, dear Chi [1]?"
Dogo said, 
  "Ill or not ill it has nothing to do with 'that' matter. Say it quickly!
   Say it quickly!"
Isan said, 
  "Even if I could say it, it would have no connection with that matter."

[1]: Dogo's full name was Dogo Enchi. "Chi" is short for Enchi.
