Dear Mr. Rossman, The introductory course to the Kabbalah that I offer in the Erna Michael College is, because of the nature of the material, rather esoteric. There is not too much that you can read on it in English. Nevertheless, I might recommend, in addition to Gershom Scholem's Major Trends in Jewish Mysticism, the book "The Kabbalah" and the Zohar by Christian Ginsburg. However, the latter book has already been superseded by the former, which remains the classic in the field.For Hebrew, the best introductory volumes are the introductions by the late Rabbi Ashlag to his commentary on the Zohar and on the writings of the Ari. Both have been reprinted recently, and are available from any bookseller.In addition, you might try two classical introductions to the Kabbalah, Rabbi Moshe Cordovero's *Pardes Rimonim* and Rabbi Joseph Irgas' *Shomer Emunim*. Frankly, I do not know if they are available for sale from the University Library, but any of the booksellers in the Lower East Side of Manhattan would have them.You might also try to obtain from the same booksellers a copy of Hillel Zeitlin's *In the World of the Kabbalah* (*Be-Olam ha-Kabbalah*).The end of the volume by Cordovero does contain a kind of glossary of Kabbalistic terms, but in order to understand it you already have to know something about the Kabbalah.I hope I have been able to answer your letter at least to some degree of satisfaction.Sincerely yours,Rabbi Norman Lamm
