Named one of Publishers Weekly’s Best Books of the Year 2007.
"Philosopher, psychologist, and mystic Wilber delivers on the subtitle’s far-reaching promise. . . . Chock full of handsome illustrations and spare, Zen-like diagrams and tables, Wilber’s work here is still accessible and at times surprisingly practical. Some language spirals up majestically, recalling great Eastern texts. Reminiscent in spirit and watershed import of Ram Dass’s Be Here Now, Wilber may well have created a popular classic for explorers on the frontiers of humanity."—Publishers Weekly
"[Wilber’s] heady multidimensional approach is deciphered in this spiffy full-color paperback filled with pop culture graphics, tables, and charts. If you are interested in consciousness, complexity, maps, multiple intelligences, and more, here is a comprehensive philosophy that puts it all together."—Spirituality and Health
