Tôzan was unwell. A monk asked, “Your Reverence is unwell. Is there anyone who does not become ill?”
Tôzan said, “There is.”
The monk said, “Does the one who does not get ill take care of Your Reverence?”
Tôzan said. “The old monk’ is properly taking care of that one.”
The monk said, “How about when ‘your Reverence’ takes care of that one?”
Tôzan said, “[The old monk] does not see that there is illness.”
