This book is an excellent addition to Reb Zalman's extensive list of books, tapes and lectures. The Paradigm Shift he has referred to in many of his works has significant implications for the way to be a Jew (aka, Halachah). Halachah includes rules and guidelines for both individuals and Rabbis, but this book is not just for Rabbis. These are important issues and I don't know of anyone else who is so effectively helping us to connect to our ancient wisdom-tradition while simultaneously showing us how to be Jews of the twenty-first century and beyond. Reb Zalman has thought long and hard about the question of what within Judaism requires some tweaking, and his suggestions for updates include cautions to not oversteer and create something unrecognizable as Jewish. We are to stay in touch with what we inherited with respect to the function of an observance, but we are invited to collaborate and to participate in ways that are meaningful to us and our communities: We are empowered to shape the Halachah of the future. Reb Daniel does an excellent job organizing the material and creating a valuable, accessible and often deeply-moving volume. In addition, he's included his own essays which enhance the original material from Reb Zalman's lectures. I'd especially recommend this for people who already know about Judaism and are interested in deepening a practice. Or for someone who believes that Jewish law is no longer relevant and is open to re-examining this belief. This is an empowering, inspiring and moving book that stimulates a deep practice and observance.
