For Mari et amicis

To Mae-Wan Ho for her inspiration and for generously allowing me to quote from her books and articles. To Martin Chaplin for permission to quote from his useful website, to Callum Coats for his diagrams, to Chris Weedon of the Water Association for his encouragement and helpful suggestions, and to Christopher Moore of Floris Books and Laura Schlivek of Inner Traditions for their helpful editing.

And special thanks to Caroline Way for allowing me to quote her poem “Still Water Meditation,” which aptly sets the theme for this book.
