Yangshan's Sermon from the Third Seat (GG25)

KOAN:

Yanghshan dreamed he went to Maitreya’s realm and was led to the third seat. A senior monk struck the stand with a gavel, and announced:
“Today, the one in the third seat will preach!”
Yanghshan arose, struck the stand with the gavel, and said,
“The truth of the dharma is transcendent, beyond words and thought.”

Yunmen’s comment: “Did he preach or not?”
