Shoyoroku - Case 53: Obaku's "Drinkers" [1]

Obaku instructed the assembly and said,
  "You are all drinkers of lees. If you continue to go on your Way like this,
   where will the 'Today' [2] 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."
