"The religion of tomorrow, according to Ken Wilber, will not be one religion, but all religions guiding their respective constituents toward oneness with Ultimate Reality. This book is Ken Wilber’s comprehensive synthesis of all the elements that make for human development from the Big Bang through the course of material and biological evolution. The recent discoveries of science, especially in the areas of developmental psychology and historical criticism, as well as mystical experience, have enabled him to bring together contemporary science, the wisdom of the world religions, and an integral presentation of the human condition with all its potential. The endless complexities of the evolutionary process gives way to a sublime simplicity, culminating in the spiritual and integral evolution of the human person toward unity with That Which Is." —Thomas Keating, author of Open Mind, Open Heart
