The old one about the non-existent gathering of monks

Let me attempt to describe what I like about Zen.

In An Introduction to Zen Buddhism, D.T. Suzuki insists that "Zen is the most serious concern in the world".

After making this assertion, he chooses to close the chapter ('Is Zen Nihilistic?') in the following manner. (For the full effect, you have to press play on the YouTube clip provided immediately after reading the extract.):

Let me conclude this chapter with the following quotation from one of the earliest Zen writings. Doko (Tao-kwang), a Buddhist philosopher and a student of the Vijnaptimatra (absolute idealism), came to a Zen master and asked:

"With what frame of mind should one discipline oneself in the truth?"

Said the Zen master, "There's no mind to be framed, nor is there any truth in which to be disciplined."

"If there is no mind to be framed and no truth in which to be disciplined, why do you have a daily gathering of monks who are studying Zen and disciplining themselves in the truth?"

The master replied: "I have not an inch of space to spare, and where could I have a gathering of monks? I have no tongue, and how would it be possible for me to advise others to come to me?"

The philosopher then exclaimed, "How can you tell me a lie like that to my face?"

"When I have no tongue to advise others, is it possible for me to tell a lie?"

Said Doko despairingly, "I cannot follow your reasoning."

"Neither do I understand myself," concluded the Zen master.

Monks? What monks? I don't know anything about no monks! I wasn't even there! Etc.
