The Sabbath by Abraham Joshua Heschel is one of the most beautifully articulated books I've read. The depth and breadth of Heschel's insight flow in almost poetic prose. His thorough understanding and personal embrace of Sabbath unwrap for the reader a concept that for many has been merely a source of legalistic obligation, or a much elusive time of rest. The philosophical separation of time and space as described in this book is mind opening, and provides a worldview that has the power to transform one's life. One can feel the peace of Sabbath while reading! I'll definitely be re-reading this book many times
