While reading up on Absinthe (it turns out that wonderful "Czech" Absinth by Hill that I have isn't genuine! nor is the neat procedure whereby one drenches a sugar cube with Absinthe and sets it alight), I discovered that Aleister Crowley had written a piece on it...

How To Summon Ye Dæmon Aleister Crowley To Visible Appearance

From an ancient Græco-Egyptian manuscript
in the Egyptian National Museum

Ye Banishing

Banish by showing a picture of Aleister Crowley to the eight directions, saying "Get Off My Cloud" at each spacemark, and each time give the Middle Finger Salute to the direction. Or ye may wear a Crowley Mask during the banishing. This will scare away any non-Thelemic entities and entice Crowley to the Circle.

On the dates of April 8, 9, and 10 in 1904, Aleister Crowley channeled the work Liber Al Vel Legis (AKA The Book Of The Law).

At first glance, this work may seem rather confusing, but upon giving further consideration, one can discover many philosophic gems.
