Shundo David Haye – Zen Priest

Yunmen was once asked by a monastic, "What does it mean to go beyond the dharma body?"
Yunmen said, "It is not difficult to tell you about going beyond it. But how do you understand the dharma body itself?"
The monastic said, "Master, please show me an example." 
Yunmen said, "I will give you an example. But first, how do you understand the dharma body itself?"
The monastic said, "It's just as it is."
Yunmen said, "This is what you have learned in the monastics' hall. Let me ask you, does the dharma body eat rice?"
The monastic could not respond. (Shinji Shobogenzo)

Well, how can you go beyond something when you don't know what it is?
