With all the talk about angels lately, this book should be required reading for every Jew. In this thin but profound volume, Rabbi Steinsaltz, coming from an authentic position within both Orthodoxy and kabbalah, clearly explains the Jewish conception of angels and how they work on the four kaobbalistic levels of Action, Formation, Creation, and Emanation. Also explained is how the mitzvahs we do create new angels to raise up the universe´s energy, and how a sin (heaven forbid) can drag the universal energies down. He then ties it all together by giving us a beautiful interpretation of the kiddush (wine blessing) ritual. After reading this book, you will never think of Torah as mere laws again!
