1. A rewriting of the famous magical word Abracadabra by Aleister Crowley. This places the name “Had,” a short form of the Egyptian Hadith that, according to some sources, represents Horus of Behedet, an area in Egypt. Hadith is the second person of the Thelemic trinity. Crowley believed it was the Word of the Aeon. One aspect of this is that it has eleven letters, thus linking the symbol of humanity, the pentagram (five identical letters) with the number of God, the hexagram, (six diverse letters). It therefore represents the Great Work of personal spiritual development.

2. Not to be confused with “Abracadabra.” Crowley declared Abrahadabra to be the “Word of the New Aeon” that would unite microcosm with macrocosm in the new phase of human evolution. In itself, the word is understood as a formula of sex magick performed within the Great Work.
