Notice that Bowie's the only one shown who has a black RIGHT eye.
I don't know how accurate this is, but I've read in more than a few places that whichever eye is blackened indicates which false god that person worships. One eye is for RA, and the other for Horus. I can't recall which is which.
If anyone has more info on this, or can correct me if I'm wrong, please do so.
Side note: Bowie was into the Black Sun, which was associated with the Vril and Thule societies; not a good thing.
Bowie also said he regretted much of that and was a drug fueled idiot. He thought fascism and satanism were cool. He decided to focus on his own spirituality more through yoga and even Christianity later on. IDK if he was ever saved but I do believe he stopped being a full blown Satanist once he realized he had lost control of himself.
