Between the two world wars, there roamed the streets of Jerusalem a man who made a nuisance of himself, pestering the populace that he was the Messiah.
Finally the “Messiah” was brought to the Chief Rabbi of Jerusalem. Rav Kook asked to meet with the deranged man alone. After a few moments with Rav Kook, the “Messiah” never again boasted his claim.
Sometime later Rav Kook revealed what produced such a wondrous effect. “I told him: ‘The truth is, there is a spark of Messiah in every Jew. You obviously have received an especially large endowment. But the quality of the spark is such that it works only as long as one does not speak of it to others.’”
Unlike many Orthodox thinkers, Rabbi Abraham Isaac Hakohen Kook did not shy away from the subject of Sabbatianism. His published works reveal a more than fleeting interest in the entire Sabbatian phenomenon, from the initial impetus of Messianic activity surrounding the person of Shabbetai Zevi, to the Hayyon and Emden-Eybeschütz controversies, to that Polish offshoot of Sabbatianism, Frankism. This interest extends to both the external, historical, as well as internal, philosophical and psychological aspects. Rav Kook is even willing to rebut the author of ‘Or la-Yesharim ‘s comparison of Herzlian political Zionism to Sabbatianism.
In the Desert–a Vision (Midbar Shur) is Rav Kook’s own record of his derashot or talks over a span of two years, 1894-1896. This book, which should have been the author’s literary debut, is the last of his works to appear in print. The reason for the delay, is that the manuscript disappeared in mysterious circumstances. The book may have arrived a century late; its message is uncannily timely. Beside their visionary quality, Rabbi Kook’s talks are remarkable for their encyclopedic knowledge. A typical derasha will start with a verse in the Torah or passage in the Midrash. From there, Rabbi Kook will weave a rich tapestry encompassing the breadth of Jewish literature: Bible, Talmud, philosophy, and Kabbalah.
