"Making a promise to work for a more peaceful world," says Cossolotto, "is a powerful way to launch this global movement. We hope millions of other like-minded people around the world will join us in this 'Peace Promise Movement.' I'm thrilled to join forces with the authors of The Peace Guidebook in this important initiative. Elizabeth and Dr. Katie are recognized experts on the individual and collective steps we can take on the path toward peace. Their book is a remarkable resource for people around the world who are seeking practical solutions to the conflicts and turmoil that cause so much pain and suffering in the global community. As the book's subtitle suggests, we desperately need to cultivate hope, healing, and harmony for the good of humanity. And a good start is to make a promise to do so."
