The Nature of Mind

"A monk asked Zen master Yunju Daoying, "What is the one Dharma?"
Yunju said, "What are the ten thousand Dharmas?"
The monk said, "I don't understand how to comprehend this."
Yunju said, "The one Dharma is your own mind.  The ten thousand dharmas are your fundamental nature.  Are they one thing or two?"
The monk bowed.
Yunju showed the monk a poem that said:

The single Dharma is the essence of all dharmas,
The myriad dharmas penetrate the one Dharma.
"Mind-only: and "nature-only,"
Don't say they're different or the same."
