As an extension of the global movement The Percolate Peace Project, The Peace Guidebook offers a practical, transformative roadmap for individuals, leaders, and organizations seeking to cultivate personal and collective peace, while also creating positive change in the world.
In a world that often feels divided, noisy, and uncertain, The Peace Guidebook is a soul-stirring invitation to return to what truly matters: a quieted soul, a love that reaches outward, and a life guided by collective compassion. This is more than a book—it’s a call to action. A blueprint for change. A spark for a global peace movement.
Rooted in authors Elizabeth Hamilton-Guarino’s and Dr. Katie Eastman’s decades of work helping people through grief, change, and transition, and inspired by the Percolate Peace Project, the book delivers Ten Principles of Peace that will help you:
- Heal what’s unresolved within you
- Navigate conflict with courage and grace
- Create partnerships rooted in values and vision
- Lead from love, even when the world forgets how
- Build real, resilient, peace-filled communities
With practical tools for real transformation—including reflective prompts, authentic stories, and accessible daily practices—The Peace Guidebook becomes more than just a read. It’s your steady companion, a well of wisdom you’ll return to again and again as you uncover your most peaceful, purpose-driven self.
Defining peace as a journey to become a guiding light in the world sets the tone for The Peace Guidebook.
Authors Elizabeth Hamilton-Guarino and Dr. Katie Eastman deliver a transformative approach that begins inside each person’s heart. Their work is organized into Ten Principles of Peace and divided into three focus areas: hope, healing, and harmony.
The authors incorporate exercises, reflection prompts, and real-life stories to demonstrate how to apply the concepts. Their ultimate goal is to provide a call to action to create a world where compassion, understanding, and healing lead the way.
With 20 people sharing stories featuring their personal challenges in establishing peace, readers will find a wealth of information for inspiration.
The Peace Guidebook offers a plan for connecting with others who have a shared vision of actively creating peace.
