One of the joys of being in Golden Dawn, or any other esoteric group for that matter, is that occasionally you can see one of the officers crack up. Each officer has their particular burden to bear. In the case of the Praemonstrator, it is having to lecture about a subject that they have done fifteen million times before (or so, it feels to them).
A particular amusing lecture to watch the Praemonstrator around is when they have to talk about the Lesser Ritual of the Pentagram. Due to the neccessarity of it being taught to every new member (aka Neophyte), most of us have attended this lecture a million times (ok, maybe it just feels like a million times). The only thing that I can imagine more boring than attending the lecture would be teaching it. You can see the eyes of the Praemonstrator twitch as they think about having to do yet another round of teaching it.
The only solution I have seen for this problem (how many times can you watch the same lecture over and over again) is to treat the lecture as if you have two audiences---one being the Neophyte, the other audience everyone else. For the Neophyte, you teach the standard "Here is where you move; these are the symbols you draw; these are the words you say." For everyone else, you take a dartboard, divide it into six parts, and throw a dart at it.
The Lesser Ritual of the Pentagram has seven layers just like the rest of the Golden Dawn rituals have. The lowest is the physical layer (the part that you are showing to the Neophyte). Everyone else gets a lecture corresponding to the layer that the dart landed in. It is not the most ideal way of teaching, but it cuts down on the snoring and eye twitching.
And if you somehow have not attended the lecture on the Lesser Ritual of the Pentagram fifteen million times, then you might enjoy reading this post on Augoeides about the Lesser Ritual of the Pentagram (click on sentence).
