Rav Kook is the greatest Jewish thinker in the last 200 years because he most fully understands the spiritual crisis of the modern Jew. Although there were a number of dynamic Jewish religious leaders who took up the mantle of leadership in order to rebuild the shattered remnants of the Jewish world in the wake of the Holocaust such as the Lubavitcher Rebbe, Rav Yosef Dov Soloveitchik and the Satmar Rov, their message was basically directed at a relatively small group of Jews. Rav Kook has a message for the entire Jewish people. His great contributions were: (1) to emphasize the dynamic nature of both the spiritual and physical worlds, and, one the one hand, tell the traditional religious Jew that the Torah is flexible and can stand up to the challenges of modernity and change, while on the other hand demonstrating the perpetual relevance of the Torah to the Jew who has a less than full commitment to it; and (2) to demonstrate the absolute necessity of the Jewish people to return to the Land of Israel and build a modern society rooted in the Torah. This fine book gives a sampling of these ideas and is a good introduction to the mind of this remarkable thinker.

Rav Kook was the first Chief Rabbi of Palestine and helped lead the continuing dialogue of Jewish Mysticism into the 20th century. This collection of his writings is both profound and beautiful. Some of the pieces such as 'The Lights of Penitance' might appeal only to scholars, but Kook's poetry can be appreciated by all. His idea of a unified Judaism where the secular and the holy both make up parts of the whole are very moving. Other themes include vegetarianism and a universal love for all people.

This book was a wonderful survey and introduction of Rav Kook's works. The philosophical texts are compelling and inspiring, the letters are touching and personal, and the poetry exposed a sincerity and passion which could not be harvested from any history book. Fantastic, meaty reading.
