大慧普覺禪師語錄 4.20

4.20

Ascending the hall, the Master said: "'If you bring up one, you must not bring up two; if you let pass the first move, you fall into the second.' If it were a patch-robed monk who knows fullness when eating and knows thirst when drinking, he would not need Yunmen to come out and run circles around it. Since Yunmen is not permitted to run circles around it, right now is there anyone who knows fullness when eating and knows thirst when drinking? Even if there were, he would still be a yellow dragon spirit."
