Baso's "Neither Mind nor Buddha"

The Reading:

When Fa-chang (752-839 CE) of Mt. Ta-mei ("Great Plum") first visited the master, he inquired about the meaning of the word "Buddha."

"The Mind is Buddha," said Ma-tsu. Upon that Fa-chang was enlightened. Later Fa-chang retired once more to Ta-mei and taught others there. When the master heard of this, he dispatched a monk to inquire what it was that Fa-chang had so learned that allowed him to presume to head a mountain lineage. Fa-chang told the monk that it was the dictum, "The Mind is Buddha." The monk noted, "Recently the master sings a different tune. Now it is 'Neither Mind nor Buddha'."

Fa-chang reacted, "That rascal deludes people to no end! Let him teach you how there is neither mind nor Buddha. For my part, I will stick to 'The Mind is Buddha.'"

When the monk reported this to the master, Ma-tsu remarked, "Indeed, the plum is ripe."

Discussion:

Ma-tsu is Baso.  He deluded many who followed him.  They are called "Masters."
