"Every heartwarming page provokes thought, insight, and smiling reverence for all beings and each moment" is how New World Library describes Guardians of Being by collaborators Eckhart Tolle, spiritual teacher, and illustrator Patrick McDonnell. "This beautiful, thought-provoking, and enlightening book pairs Tolle's Power of Now mindfulness with McDonnell's beloved Mutts characters."

New World Library, publisher of "books and audios that inspire and challenge us to improve the quality of our lives and our world", celebrated its 30th anniversary in 2007 buoyed by the continuing success of Eckhart Tolle's The Power of Now and Practicing the Power of Now. In 2001, New World Library worked with the Joseph Campbell Foundation to introduce The Collected Works of Joseph Campbell series.
