3This work, Volume II of The Secret Doctrine of the Gaon of Vilna, introduces the reader to the virtually unknown Kabbalah School of the Gaon of Vilna. This cosmology incorporates an ancient prophesy mandating a messianic interface between Kabbalah and science. The reader is taken on an exploration of the most challenging "secrets of secrets" to be found from among the entire corpus of the kabbalistic teachings of the Jewish sages: the secret mission of Mashiach ben Yoseph (the Josephic Messiah) and the Twin Messiahs, the cosmic drama of the Sacred Serpent and its role in accelerating technology, the Feast of Leviathan and its higher dimensional "flesh", and Metatron - Prince of the Presence - the ultimate key to unlocking the Gaon's Kabbalah system, specifically the doctrine of Kol HaTor, and for that matter, the entire Torah and the cosmos.
