This (“The Multiplicity of Thelemas“), published by Thelemic Union, is a recent essay by yours truly.
It covers the notion that Thelema as a system may potentially be as diverse as the number of people who practice or uphold it.
It also flies against needless dogmatism in general.
I am happy to report that Thelemic Union has published my essay “Learning the Joy of Existence” (site founder and manager IAO131 renamed it “Learning the Joy of Existence in Thelema,” presumably to make it appear more relevant) on their site.
This essay covers the notion that existence is inherently joyous from a Thelemic perspective, and how to view it as such by engaging in the trances that Crowley discusses in his short book Little Essays Toward Truth.
Feel free to check it out.
