Shoyoroku - Case 86: Rinzai's Great Enlightenment

Rinzai asked Obaku, 
  "What is the great meaning of the Buddha-Dharma?"
Obaku hit him. This happened three times. Rinzai then took his leave and went
to see Daigu. Daigu asked, 
  "Where have you come from?"
Rinzai said,
  "From Obaku."
Daigu said, 
  "What did Obaku have to say?"
Rinzai said,
  "I asked him three times, 'What is the great meaning of the Buddha-Dharma?'
   and I got his stick three times. I don't know if I was in error or not."
Daigu said,
  "Obaku was overly gentle like an old grandmother; he completely exhausted
   himself for your sake. Yet you come here and ask if you were in error
   or not!"
With these words, Rinzai came to great enlightenment.
