It doesn't really matter where they have in terms of location. But, where they gather, that's where all the fun drama is happening. And I know a lot of people learn from each other. They become the best friends forever. And some of them get married - this is what I heard. :) So this is a place where people gather and learn from one another.
And not only from the great teachers but also from all the people that you bump into during the break session. So, I really recommend that if you have a chance, please go and visit Mindvalley you'll never regret it.
