I don't like the idea of it, just the same way I don't like the idea of love being just "chemical compatibility"
Yeah I agree. "Brain exercises" doesn't have the same ring to it like "meditation" does lol. But in the case of school, I do think a word with such a strong religious/spiritual association could be problematic. Some people will only see it as a religious exercise and likely get all uptight about it, which sounds like is already happening. You know there will be devote Christians that are convinced that the school is trying to convert their children to a Buddhism haha
Using a different term could help that scenario
