Master Zhaozhou asked a newly arrived monk, ‘Have you been here before?’
The monk answered, ‘Yes, I have’.
Master Zhaozhou: ‘Go drink tea’.
He then asked another monk the same. The monk replied, ‘No, I haven’t been here’.
Master Zhaozhou: ‘Go drink tea’.
The head resident of monks asked the Master, ‘To the one who had been here, you
say “drink tea”, and to the one who hadn’t been here, you also say “drink tea”. Why?’
Master called the head monk loudly. Upon his responding, Master Zhaozhou said,
‘Go drink tea’.
