Crooked Cucumber is a book about Suzuki-Roshi. Zen Mind, Beginner's Mind is a book he wrote. More accurately, Zen Mind, Beginner's Mind is a compilation of talks given by Suzuki-Roshi. You can get the flavor by clicking right here.
Called "a modern spiritual classic," Zen Mind, Beginner's Mind starts with this statement:
In the beginner's mind there are many possibilities, but in the expert's there are few.
I interpret this saying to suggest that a truly "Zen mind" must be a "beginner's mind." The essence of our reality is that we create it, which means that we can always begin anew. "Possibility" is the category of most importance to us.
The essence of the "political world," in which we most immediately live, is that this is a world that we make ourselves. Because we make our world, and then remake it again, that world comes, always, "Out of Revolution," which just happens to be the title of another good book. That book is by Eugen Rosenstock-Huessy (Out of Revolution: Autobiography of Western Man).
Lots of good books, aren't there? Get through with one, and it's time to begin another!
