Let's mean by "professionally engaged" yoga teachers who earn money from this. And let others be "amateurs" in the best sense of the word.
It is clear that "professionals" are well versed in physiology, psychology, philosophy of yoga, and generally mega-positive smarties and sweethearts. But nothing human is alien to 99.9%! Of course, a “professional yogi” should have a kind of good self-control and remain calm, while those around them should lose their desire to provoke aggression or behave in some way inadequately. However, it can be different. And if you set yourself a goal, it turns out that not everyone managed to become enlightened, although they tried to seem like that. As a rule, there are still some attachments, principles, "sore" topics, etc.
By the way, on the Internet every now and then pop up a variety of hard-hitting stories and scandals associated with very popular "professional yogis". Unfortunately, there are examples of aggression. Anyway, something very similar to her.
P.s. Likewise, one might wonder, is it possible to piss off a psychologist / psychiatrist / concierge in a five-star hotel / voodoo sorcerer? Unfortunately you can.
Not everyone. In yoga, there are ways to work with anger, when an emerging destructive emotion is transformed into a constructive one. Therefore, the result may be unexpected. For example, a yogi will want to hug you or start laughing or crying. But advanced practitioners will still remain calm, because their perception of the world is not due to external reasons. They treat other people's aggression in the same way as a dry branch of a tree that falls on them. In addition, while doing this strange business, it is useful to remember the words of the Buddha: “You cannot throw hot coal at someone and not get burned yourself.”
Yes, absolutely any person can be brought to the boiling point. It's just that those who do yoga have this point further, if people who don't do it.
