Case 11: Obaku's "Drinkers of Lees"

Obaku, instructing the assembly, said,
  "You are all drinkers of lees. If you continue to go on your Way like this,
   where will the 'Today' [The world of nirvana] be? Do you know that in
   this great empire of Tang there is no Zen master?"
Now a monk came forward and said,
  "What would you say to the fact that in various places there are people who
   accept students and direct their assemblies?"
Obaku said,
  "I don't say that there is no Zen; I only say that there is no master."
