This book captures hundreds of anonymous expressions of gratitude solicited from online contributors through the gratitude.is project. It also contains reflective essays from those affected by this project. Gratitude explores how the process of expressing gratitude can change how we see the world. Leading happiness research shows that keeping a gratitude journal can result in increased well-being and better health. Inspired by this growing movement, the book is a meditative space with illustrations, hand-made felt landscapes, videos, and a unique soundtrack by Buddhist monks. Try it on, explore, play with it, and have fun!
