In The Key to the True Kabbalah, Franz Bardon demonstrates that mysticism of letters and numbers -- the true Kabbalah -- is a universal teaching of great antiquity and depth. Throughout the ages, adepts of every time and place have achieved the highest levels of magical attainment through the understanding of sound, color, number and vibration as embodied in the Kabbalah. This book, the 3rd in Bardon’s remarkable texts of Hermetic magic, is nothing less than a practical guide to such attainment. Using the common German alphabet Bardon guides the reader through ever greater levels of Kabbalistic achievement. No other available text reveals as great a depth of Kabbalistic wisdom or provides the reader with as much practical training. Though intended primarily as a working text for those who have completed Bardon’s 1st and 2nd volumes, Initiaiton into Hermetics and The Practice of Magical Evocation, the present work stands on its own.
