The infamous Satanist Aleister Crowley first learned how to do magick using the word abracadabra
from his teachers in the original Golden Dawn. He learned, however, that the correct usage was abra-ha-dabra. This, because the numerical value of abrahadabra is much more convenient than the numerical value of abracadabra. "Abra-ha-dabra" has the value of 418, when rendered from the Hebrew. And coincidentally, 418 equals many other convenient things.
"This book shall be translated into all tongues: but always with the original in the writing of the Beast; for in the chance shape of the letters and their position to one another: in these are mysteries that no Beast shall divine. Let him not seek to try: but one cometh after him, whence I say not, who shall discover the Key of it all. Then this line drawn is a key: then this circle squared in its failure is a key also. And Abrahadabra. It shall be his child & that strangely. Let him not seek after this; for thereby alone can he fall from it."
