Caroline Myss describes herself as a medical intuitive. This book is a summation of her insights and conclusions gained over 14 years of practising and teaching others. She describes her own extraordinary experiences which first led her to commit to this work, and how study and a gruelling schedule of workshops finally led her to teaching others how to "read" their own health. The book scores well in establishing and explaining its own language, drawing together 3 rich religious traditions and showing how each of them describe a central truth about the journey of spiritual growth. She compares the Hindu teaching of the seven chakras, the seven Christian sacraments and the ten points of the Tree of Life described in the Kabbalah, the mystical tradition of Judaism. Although there are ten points to the Tree of Life, Caroline Myss shows that some of these points are properly paired, so that they too describe seven stages of spiritual development, each with its own sacred truth. The majority of the book takes each chakra or stage in turn, describing the ways in which we are called to develop at each level, and the physical symptoms which can arise when we fail to heed this call. I found the book rich in insight and wisdom. Where the book worked particularly well for me was the frequent use of examples from real life case histories, relating intuitive images to the circumstances of the patient's life, and how the patient had subsequently healed, or sometimes how they had failed to heal. This format made it easy to draw parallels and comparisons with one's own life or that of friends. The unsentimental and scientific attitude of the author also helped to encourage the same detached approach for me as a reader. There is much food for thought contained here, whether you consider yourself healthy or not. Along the way, the book has many interesting things to say about the development and use of intuition, which Caroline Myss graphically describes as "symbolic sight", and the spiritual journey in general. I felt that the end of the book was a little disappointing. The guidance for the reader - a daily meditation which amounts to a personal health check - comes only in the form of a very brief "afterword". A lot of information has gone before, but a more thorough description, and perhaps some examples of how people have helped themselves in this way, would have offered me more encouragement to do the very thing that the book aims to promote. But this is a minor point, and perhaps experience with the meditation would be worth more than a few more pages of description. Overall, I heartily recommend this book, a thought-provoking read in an engaging style.
