Mumonkan - Case 30: This Mind is Buddha

Daibai asked Baso:
  "What is Buddha?"
Baso said:
  "This mind is Buddha."


Mumon's Comment:

If anyone wholly understands this, he is wearing Buddha's clothing, he is
eating Buddha's food, he is speaking Buddha's words, he is behaving as
Buddha, he is Buddha.

This anecdote, however, has given many pupil the sickness of formality. If
one truly understands, he will wash out his mouth for three days after
saying the word Buddha, and he will close his ears and flee after hearing
"This mind is Buddha."

   Under blue sky, in bright sunlight,
   One need not search around.
   Asking what Buddha is
   Is like hiding loot in one's pocket and declaring oneself innocent.
