The Qabbalah

For a good introduction to Qabalah, kaballah, etc
Read
Dion Fortune, an initiate of Alpha et Omega, wrote the seminal book The Mystical Qabalah, widely considered one of the best general introductions to modern Hermetic Qabbalah.

Tree of Life

Hermetic Qabalah (From the Hebrew קַבָּלָה "reception", usually transliterated with a 'Q' rather than a 'K' or a 'C', to distinguish it from Jewish Kabbalah and Christian Cabbalah) is a Western esoteric and mystical tradition. It is the underlying philosophy and framework for magical societies such as the Golden Dawn, Thelemic orders, mystical societies such as the Builders of the Adytum and the Fellowship of the Rosy Cross, and is a precursor to the Neopagan, Wiccan and New Age movements.^[1] The Hermetic Qabalah is the basis for Qliphothic Qabala as studied by left hand path orders, such as the Typhonian Order.
Hermetic Qabalah draws on a great many influences, most notably: Jewish Kabbalah, Western astrology, Alchemy, pagan religions, especially Egyptian and Greco-Roman (the latter being from which the term "Hermetic" is derived), neoplatonism, gnosticism, the Enochian system of angelic magic of John Dee and Edward Kelley, hermeticism, rosicrucianism, Freemasonry, tantra and the symbolism of the tarot. Hermetic Qabalah differs from the Jewish form in being a more admittedly syncretic system, however it shares many concepts with Jewish Kabbalah.

Footprints in the Chamber - Towards a Quantum Qabbala by Fra.: +0- 
           
          The Qabbala has through the ages been used as a directory towards 
          the understanding of the universe and man`s relationship to it. 
          Since former Aeons of magick have had their perceptions rooted in 
          the observance of simple cause and effect relationships, the Qabbala 
          itself, having attained its nascence in the earlier traditions, was 
          unfortunately bogged down by this limited apprehension of the 
          universe. Here mathematics as used in a more or less Pythagorean 
          context provide a sort of key with which to approach the 
          unfathomable nature of human consciousness. 
           
          To this very day there are groups which still adhere to and openly 
          practice the more traditional ramifications of Qabbalistic 
          principles which are still firmly rooted in the mire of Nineteenth 
          Century Newton-sewed-it-all-up-there-are-no-more-mysteries physics. 
          But of course, owing to the leaps and bounds acquired by a very 
          unpredictable but consistent quantum model of reality as observed in 
          our laboratories, this simplistic view is necessarily obsolete. We 
          no longer live, we have learned (if indeed we ever did) in a simple 
          cause and effect universe where the source can always be gleaned 
          from observable effect. For the same reasons, Newtonian-based magic 
          must give way to a more quantum model. Newton`s apple must now take 
          into consideration Heisenberg`s Uncertainty Principle. The secret 
          wisdom must follow suit towards quantumization. 
           
          Another unfortunate tendency of some modern practioners of Qabbala 
          is to continue to regard everything from the standpoint of the 
          Demiurge, Yahweh, which of course is the basis of the now obsolete 
          (and dangerous) Judeo-Christian foundation of religious thought 
          which has held western civilization in its thrall for about two 
          thousand years. Personally I find it amazing that modern 
          practioners, who despite no real Semitic disposition still practice 
          an unmistakably orthodox Jewish mysticism. It was Aleister Crowley, 
          that great Qabbalistic agent provocateur, who initiated the process 
          of liberating the Qabbala from its otherwise Judaic orientation. 
          (This is not anti-semitism but a necessary step towards individual 
          development. It must also be stated that a Qabbala had been in use 
          centuries earlier by the Egyptians. The Jews merely adopted it to 
          their own religious precepts. They didn`t invent it. The actual 
          origin most likely predates Egyptian history.) 
           
          Crowley emphasized that the enlightened magician must, after careful 
          study and application of his knowledge, develop his own Qabbalistic 
          framework. By virtue of this the magician has arrived at a more 
          chaotic paradigm in opposition to a purely empirical view. Crowley, 
          by adapting the Qabbala to a Thelemic context initiated that first 
          leap forward into the quantum age. Thus, the foundation for a more 
          quantum/chaotic system was lain.
