In this fascinating book, Roderick Main examines meaningful coincidence or what Swiss psychiatrist C. G. Jung called synchronicity. Moving beyond Jung's psychological theory, he explores the plausibility and value of viewing synchronicity as a form of spiritual experience and clarifies connections between the phenomenon and a range of traditional spiritual concepts, including numinosity, miraculousness, transformation, unity, transcendence and immanence, providence, and revelation. Through the detailed analysis of two remarkable series of synchronistic events, Main illustrates and further develops these connections. He also includes an examination of the alleged synchronistic basis of the ancient Chinese Oracle of Change, the I Ching.
