Doubt

It is the playful sense of humor that strikes me in  Zen Master Raven, sayings and doings of a wise bird, Robert Aitken.

Doubt
One evening Woodpecker asked, The term doubt seems to be used in an unusual way in our practice. How do you understand it?
Raven said, "What's this?"
Woodpecker asked, "Well, what is it?"
Raven asked, "What is it?"

Sometimes it is best to hold still, where there is no gasping for words.
