A dharma teaching by Huangbo (d. 850):
Huangbo said to the assembly, “You people are all slurpers of dregs. If you travel like this, where will you have today? Do you know that in all of China there are no teachers of Chan?”
At that point a monk came forward and said, “What about those who guide followers and lead groups in various places?”
Huangbo said, “I don’t say there’s no Chan, just that there are no teachers.”
