Role of the brain and mind


Do you mind explaining the role of the brain and the mind in our thought work?

I hear phrases like, “mind management,” and “your brain offers X thought.” Could they be used interchangeably here? Is there such a thing as “brain management” and “your mind offers X thought”? Is it just semantics or is there a scientific reasoning behind using one word over the other? I wonder how the brain and mind works together.
