Shoyoroku - Case 14: Attendant Kaku Offers Tea

Attendant Kaku asked Tokusan, 
  "Where have all the past saints gone?"
Tokusan said,
  "What? What?"
Kaku said,
  "I gave the command for an excellent horse like a flying dragon to spring
   forth, but there came out only a lame tortoise."
Tokusan was silent. The next day, when Tokusan came out of the bath, Kaku
served him tea. Tokusan passed his hand gently over Kaku's back. Kaku said,
  "This old fellow has gotten a glimpse for the first time."
Again, Tokusan was silent.
