Judaism, like all the great religions, has a strand within it that sees inward devotion, the opening of the human heart to God's presence, to be the purpose of its entire edifice of praxis, liturgy, and way of life. This voice is not always easy to hear in a tradition where so much attention is devoted to the how rather than the why of religious living. The devotional claim, certainly a key part of Judaism's biblical heritage, has reasserted itself in the teachings of individual mystics and in the emergence of religious movements over the long course of Jewish history. This volume represents Arthur Green's own quest for such a Judaism-as a rabbi, as a scholar, and as a contemporary seeker. This collection of essays brings together Green's scholarly writings, centered on the history of early Hasidism, and his highly personal approach to a rebirth of Jewish spirituality in our own day. In choosing to present them in this way he asserts a claim that they are all of a piece. They represent one man's attempt to wade through history and text, language and symbol, and an array of voices both past and present while always focusing on the essential questions: "What does it mean to be a religious human being, and what does Judaism teach us about how to be one?" This, the author considers to be the heart of the matter.
