ABRAHADABRA is a magickal word of eleven letters, revealed to Aleister Crowley in 1904 during the writing of The Book of the Law. Its gematric value is 418, a number of great significance in Thelema and in the Qabalah—the number of the Great Work, the Stone of the Wise, and the synthesis of opposites. The word encodes a formula of unification: Abrahadabra is said to mean "I will create as I speak" (from Hebrew abra k’dabri), and it represents the seal of the New Aeon, joining the energies of the Macrocosm and the Microcosm in a single utterance.

Position on the Tree of Life

In the schema of Liber 777, ABRAHADABRA corresponds to the 18th path of the Tree of Life, which is the path of Teth (the Serpent) and links Chesed (Mercy) to Geburah (Severity). This path runs on the Middle Pillar at the level of Tiphereth (Beauty), the sixth Sephirah, where ABRAHADABRA appears as a magickal formula. The 18th path is also associated with the zodiacal sign Leo, the Lion, whose fire and royalty echo the word's lion-headed imagery in Thelemic iconography.

Astrological and planetary correspondence

The path of Teth is ruled by the sign Leo (Arieh), the Lion. In Liber 777, Leo's planetary ruler is the Sun, and the Sun itself corresponds to Tiphereth—the very Sephirah where ABRAHADABRA is stationed. Thus the formula unites the solar energies of Tiphereth (harmony, the Son, the Redeemer) with the fiery, creative power of Leo, channeled through the serpentine wisdom of the Path of Teth.

Historical context

The word ABRAHADABRA first appeared in the Book of the Law (Liber AL vel Legis), dictated to Crowley on April 9, 1904, in Cairo. In the text, it is written as "Abrahadabra" and is described as the "word of the Aeon" and the "crown of the Serpent." Crowley later devoted extensive commentary to it, especially in The Vision and the Voice and Magick in Theory and Practice, where he calls it "the Formula of the Great Work."

Its letter-count, 11, signifies the completion of the Great Work through the union of the 10 Sephiroth plus the 11th (Da'ath or the hidden sphere). The word's gematria of 418 ties it to the number of the Great Beast (666 reduced to 418 in certain computations), and to the formula of IAO (the dying-and-rising god) and Therion (the Beast). In Thelemic ritual, ABRAHADABRA is often used as a closing or sealing word, equivalent to the Qabalistic "Amen" but with a specific New Aeon charge.

Historically, ABRAHADABRA has been confused with the older charm Abracadabra, which dates to the 2nd century Gnostic physician Serenus Sammonicus and was used as a magical incantation against fevers. Crowley explicitly distinguished the two, noting that Abracadabra was a degeneration of the true formula. He found in ABRAHADABRA a perfect expression of the formula: the Five (the microcosm, humanity) entering into the Six (the macrocosm, the Sun), producing the Eleven (the Great Work).

In Liber 777

In table row CLXXXVII (column XLI: Magical Formulæ), at step 18 (Path 18), the single entry is ABRAHADABRA. It stands alone, without further cell values, marking this path—the Serpent's path between Mercy and Severity—as the direct carrier of the word of the New Aeon. Around it, sister cells show other potent formulæ: BABALON · VITRIOL at Binah, IHVH at Chesed, IAO:INRI at Tiphereth, and AUMGN at Path 24. But on Path 18, ABRAHADABRA is the sole occupant: the formula of the Crowned Serpent, the Word of the Aeon.
