Philip S. Berg (original name Feivel Gruberger, ; August 20, 1927 – September 16, 2013) was an American rabbi and dean of the worldwide Kabbalah Centre organization. Berg was a great populariser of Ashlagian Kabbalah. Having written a number of books on the subject of Kabbalah, Berg expanded its access to a greater audience than traditionally permitted, one which included secular Jews, non-Jews and women. Berg initially aimed at returning alienated Jews to their heritage through the teachings of Yehuda Ashlag, however he later adopted a more universalistic approach. There is disagreement about whether Berg's teachings, as relayed through the Kabbalah Centre, have sufficient grounds and/or genuine authority according to halakha (Jewish law), as they include some dogmas and translations differing markedly from those of more-traditional Kabbalists. Some Jewish scholars emphatically reject such teachings, deeming them as foreign to both the Kabbalah in particular and to Judaism in general. In poor health following a stroke in 2004, Berg died on September 16, 2013. Biography Berg was born as Shraga Feivel Gruberger in 1929 in Brooklyn, to an Orthodox Jewish family. His father, Max Gruberger, immigrated from Nadvorna, Galicia (now in Ukraine), and worked as a clothes presser in Williamsburg. In his youth, Berg underwent Talmudic education at Lakewood Yeshiva under Aharon Kotler. He later returned to Williamsburg, where in 1951 at age 22 he received ordination from Yeshiva Torah Vodaas. Berg went into the business world and worked as an insurance agent for New York Life. He also became involved in real estate, and by 1962 it is claimed he was a millionaire. It is likely that he began to be called Philip during this time, as it is usual practice among Jews with Yiddish names to use an English equivalent to be more comfortable in a secular environment. Berg's first wife, Rivkah Brandwein, had an uncle named Yehuda Brandwein, whom Berg first met on a trip to Israel in 1962. Brandwein, a Hasidic rabbi from the Stretiner Hasidic dynasty and a close student in the Kabbalistic circle around Yehuda Ashlag, would become Berg's Kabbalistic mentor. Brandwein was the head of the Religious Department of the Israeli national workers union, Histadrut, and established Yeshivat Kol Yehuda (named after Ashlag) as a continuation of his mentor's yeshiva/publishing house "Beit Ulpana Itur Rabbanim". The uniqueness of Kol Yehuda was that students focused on kabbalistic study. The students would receive a salary to
