As one with a lifelong interest in mysticism, I have been reading Rumi for forty-five years now. Unfortunately, I cannot yet read the originals, and I have had to intuit the sense in some rather bloodless interpretations. Harvey, however, seems to hit it just right. To the degree that we can speak of these things during a person's lifetime, he seems to me to be a genuine mystic himself, passionate and full-blooded as the real thing usually is. Six months ago, I gave a copy of this to a much younger friend who had discerned the via negativa with no external guidance before we met. He rejoices in the book and is delighted to find words that exactly mirror his own untaught discoveries. I do not normally gush over such books. I was rigorously trained in Catholic theology and philosophy, hold a graduate degree in East Asian religion and identify myself as a Christian. I am not expert in Islam, though I know far more than the average reader, having edited one work on Rumi. So I tend to cast a jaundiced eye over most work like this. But if I were forced to reduce my library to a scant hundred volumes, The Way of Passion would still find an honored place. Rumi, though heterodox like all mystics, spoke powerfully not only to the Sufis of his time but to orthodox Muslims, Jews and Christians. Though Harvey certainly does not rank with Rumi, his interpretation can speak meaningfully to all persons of good will who do not barricade themselves behind denominational lines. On the basis of this book alone, I would read anything that Harvey writes.
