Being an interest of mine I had heard of this years ago.
Personally anyone who make any extraordinary claims, isn't a good teacher, they are just exploiting their students.
I've been lucky to have couple great teachers, who haven't been egos, and just passed on knowledge. I had one teacher who was, a massive ego, and he ended up having his comeuppance, and is now a lonely old fool. Actually my current teachers, who are were student of him, with me, actually dumped him, as he abandoned us an moved back to Hong Kong, because his wife left him for being such an intolerable oaf, and frequenting prostitutes, and he acted like it was the end of the world. So after months of no contact, we let him know we wanted to move on, at the very least for the senior students to have some source of coaching.
Absurdly he was more upset that we wanted to learn from his teacher. Yet he never took it out on his teacher, dispute this guy being happy to offer coaching. Wouldn't anyone be happy that we want to learn from their teacher? Not him. He constantly sucks up, apparently, but never listened. That is what this guy says, and and is well respected.
It also turn out he was pocketing our insurance and membership, despite carrying association status.
He basically never wanted us to train with other people, so we wouldn't be able to compare. I don't mean in a disrespectful way, simply that he wanted to be our only source of knowledge, so we would know no better.
Best advice in MA. Stay out of politics. It is mostly BS, and attempting to promote some commercial interest.
Honestly my teachers are not total atheist, I am. I do understand how on a personal level some belief can help them, but it is not like vid. If it was, I would just leave. It is a personal belief, not forced down our throats.
