A very basic introduction to the use of Thurisaz in black magick and witchcraft
Though I wish he might have mentioned the works of Ekortu such as his Thursakyngi book series which are integral to this path, this is a decent and interesting introduction to the Chaos Gnostic, Thursian path.
Related, he also did a video regarding Rökkatru. Also worthy of a watch...
Here is a link to information on the works and website of Ekortu which I highly reccomend. You can also find him on Instagram @Ekortu.
