The Knowing Heart draws a sweeping picture of the Sufi way, covering such topics as the structure of the spiritual path, the centrality of love, Sufi psychology, the importance of spiritual friendship and community, spiritual faculties, and the sources of the Sufi tradition. Clearly the fruit of personal, heartfelt experience, Helminski's work is a refreshing addition to a body of literature that all too often neglects the profound role that tradition plays in Sufism. He accomplishes this task without subverting either tradition or the needs of his audience. In marked contrast to the "pick-and-choose" spirituality that seems so popular nowadays, The Knowing Heart speaks from the heart, yet a heart humbled and submissive to the sources which enliven it.
