The 5 and the 6
The 5 pointed star (the pentagram) symbolizes man, a.k.a. the microcosm (that which is within us, in a spiritual sense). The hexagram, the six-pointed star, symbolizes God, also known as the macrocosm (all that is without us).
This is the heart of all magick, and indeed the heart of very nearly any spirituality or religion on Earth: the union of man and God.
God, spiritual and intangible, benefits through this union by having carnal knowledge of the transitory material world. We, as humankind, benefit from God by experiencing a taste of true eternity, which we have forgotten under the weight of the ego-mind, day-to-day pressures, and the overall drudgery of life.
There are many ways to visualize this marriage of the Macrocosm and the Microcosm, including either a pentagram within a hexagram, or a hexagram within a pentagram, which symbolizes God within us.
The harmonious juncture of the Microcosm and Macrocosm is the experience of the Higher Self, or in technical verbiage, “Knowledge and Conversation of the Holy Guardian Angel.”
Crowley’s formula for representing this union of the 5 and the 6 is his eleven letter word: “ABRAHADABRA,” which contains six consonants and five vowels. Crowleyrestored the word Abrahadabra from the more famous spelling “Abracadabra,”which was used in ancient amulets to ward off disease.
The first known mention of Abradabra was in the 2nd century AD in a poem called De Medicina Praecepta by Serenus Sammonicus, physician to the Roman emperor Caracalla.
