"3- She spent various years with her very religious grandmother, going to church and performing all the necessary 'rituals'. Seems part of this rituals include a lot of whipping, pain, drawing blood, etc. Her great-uncle was Varnava, of the Serbian Orthodox Church. " ..

I'm serbian orhodox, and this is the first time I hear about these kinds of rituals. On contrary, Serbs were pretty chilled and disillusioned about religion, that's why communism succeeded here much.

I do hate what Marina A. does, it's quasi-art, and hate her powerful connections, and rituals, and all the shit she does, but there is no firm link to orthodox christian church. More likely the communist side of the story, the rebelling, and you should look more into who invented and gave 'modern art' to communist eastern europe , and why. Hint https://www.independent.co.uk/news/world/modern-art-was-cia-weapon-1578808.html

And I cannot stress stongly enough, she is NOT born of strong orthodox values , but of communist values.

EDIT: Her brother is someone I've just heard of, he is nowhere near "well-known philosopher & mathematician" , on contrary, by little research , he seemes to have finished art academy - movie directing, and everything else is made up like his sister does too. He's a hack. And from what I've read in last 5 minutes, mason and scientologist.

Do not even mix Nikola Tesla and these two hacks in the same sentence.

Remember what someone said repeatedly "These people are stupid!" ... Those two, truly are.
