Elegant, passionate, and filled with the love of God"s creation, Abraham Joshua Heschel"s The Sabbath has been hailed as a classic of Jewish spirituality ever since its original publication-and has been read by thousands of people seeking meaning in modern life. In this brief yet profound meditation on the meaning of the Seventh Day, Heschel introduced the idea of an "architecture of holiness" that appears not in space but in time Judaism, he argues, is a religion of time: it finds meaning not in space and the material things that fill it but in time and the eternity that imbues it, so that "the Sabbaths are our great cathedrals."
