American readers of this blog might want to know that one of the senior adepts of the Hermetic Order of the Golden Dawn, Carrie Mikell & Aaron Leitch are running their ceremonial magic workshops in ceremonial magic starting from March 3.
You can find out more here. Aaron knows his stuff and is an expert on ceremonial magic and Enochian, having published some important books on the subject and if you want to learn more about practical Golden Dawn magic, then this is a good one to learn all about it.
There are lots of different teachers within the Golden Dawn community who are offering courses either online or offline. They are well worth looking at if you cannot join a full temple. Each teacher emphasizes their own practical work and you can learn more from these sorts of workshops than from pages of writing. It is worth jumping into a car and booking a hotel in a strange part of the world to visit. I did a lot of that when I lived in the UK and do run workshops both online and off myself now.
