Edited by Nahum N. Glatzer With a new Foreword by Rodger Kamenetz   "The question I put before you, as well as before myself, is the question of the meaning of Judaism for the Jews. Why do we call ourselves Jews? I want to speak to you not of an abstraction but of your own life . . . its authenticity and essence." With these words, Martin Buber takes us on a journey into the heart of Judaism--its spirit, vision, and relevance to modern life.
