What do you know about the religion of Thelema, and does it tie in somehow with the Black Dahlia?

Thelema is the religion made popular by Aleistar Crowley.
Hails,
Silence
The link has a full description.

I’m not to sure about it but I googled the two terms and plenty of info came up with the two related. I only know of Thelema from the Marilyn Manson lyrics in Misery Machine. Sorry.

Thelema is a branch of ceremonial magick popularized by Aleister Crowley. And I doubt that it actually has anything to do with the Black Dahlia case.

I dont know what black dahlia is. Thelema is an offshoot of Golden dawn which is an offshoot of Freemasonry. It was created by Aliester Crowley.
