The enneagram is an ancient nine-pointed diagram which symbolizes the evolution of any process. Like the I Ching hexagrams or the Kabalistic Tree of Life, the enneagram can be used for understanding many different areas of endeavour, and to enhance our intuition, our capacity to see situations holistically, and our ability to find connections between different areas of knowledge and experience. This book explains its potential and discusses the fundamental ideas woven into the symbol. The author then applies the insights of the enneagram to various topics ranging from sex to the solar system.
