Dragon Rouge, not to be confused with the Baz Luhrmann movie, is one of the more obscure left hand path traditions I have come across in my virtual wanderings.
Otherwise known as the Ordo Draconis et Atri Adamantis, Dragon Rouge is a Nordic order grounded in four primary magickal traditions: the Goetic Qabalah, the Odinic Runosophy, Tantra and Alchemy. You can read more for yourself at www.dragonrouge.net.
For my Christian readers, I would like to ask, have you ever wondered how you engage left hand paths? Thoughtfully I mean? Personally, I find it interesting that Dragon Rouge defines the left hand path as “going against the grain”. Is that not, in certain respects, what Jesus calls Christians to do? I think there are connection points here for those open to the Spirit’s leading. In my own experience, left hand path practitioners are open to conversing with Christians who don’t run with the herd but think for themselves.
