A little while back, U.S. Grand Lodge of Ordo Templi Orientis soft-launched its own YouTube channel at https://www.youtube.com/c/OrdoTempliOrientisUSA.
The channel started with introductions to O.T.O. and Thelema as well as playlists of related video content. Over time, the channel has uploaded more content, most recently, provided by the Education Committee of USGL.
The latest additions are presentations on MesoAmerican Maize Magick and Liber Samekh.
