My favorite yoga teacher often starts our classes with this quote. I asked him for the source and he sent me to a book called Bicycling Bliss by Portia H. Masterson. While trying to contact the author for permission to use her words, I learned that she died a few years ago. So I continue spreading her good words in the form of this little tunnel book. Each book in the edition uses different papers and a different technique for applying the color, although the text and general layout are the same for each of the ten copies.
