Cara Soror, 
Do what thou wilt shall be the whole of the Law. 
Let me begin by referring to my letter about the motto 
and make clear to you the working of this letter. 
In this motto you have really got several ideas combined, 
and yet they are really, of course, one idea. Fiat, being 811, 
is identical with lAO, and therefore FIAT YOD might be

motto should give you a very clear idea of the sort of way in 
which Qabalah should be used. I think it is rather useful to 
remember what the essence of the Qabalah is in principle; 
thus, in your correspondence for Malkuth, Yesod, and Hod 
you are simply writing down some of the ideas which pertain 
to the numbers 10, 9 and 8 respectively. Naturally, there is a

I, No.5, it is quite easy to prove 1=2=3=4, etc. 
On the other hand, you must be careful to avoid taking the
