But belief systems are like the university where I teach or the country of Canada: they don't exist “out there” in the world, but only in the left brain and only when people are thinking about them. Take some of the most popular beliefs: my country is the best; my religion is the only true one; I think so-and-so should be president of the country. None of these beliefs exists independently in the world, but only in the mind and only at the moment someone creates them through the process of thinking.
