Forty is Mem, Water, the Hanged Man; and Eighty is Pe, Mars, the blasted Tower. These Trumps refer respectively to the "Destruction of the World by Water" and "by Fire." The meaning of these phrases is to be studied in my Rituals of Magick, such as Book 4, Parts II & III. Its general purport is that He is master of both types of Force. I am inclined to opine that there is a simpler and deeper sense in the text than I have so far disclosed
"at your arms" is a curious turn of phrase. There may be some cryptographic implication, or there may not; at least, there is this, that the use of such un-English expressions makes a clear-cut distinction between AIWAZ and the Scribe. In the inspired Books, such as Liber LXV, VII, DCCXIII and others, written by The Beast 666 directly, not from dictation, no such awkward expressions are to be found. The style shows a well-marked difference.
