One of Zen master Dogen's most beloved writings is a relatively short essay called "Sansuikyo," or the Mountains and Waters Sutra. In this episode, I reflect on two aspects this work: The statement that mountains and waters are, in of themselves, words of the Buddha, and the fantastic imagery of "mountains walking." I only cover a few paragraphs of the Sansuikyo, but it is enough to open up a profound spiritual inquiry.
