The Difference Between The Mind And The Brain
The mind is different from the brain. God is spirit. He is brainless but He is not mindless. When we physically die, we leave our brains to the grave but we will not be mindless in the other dimension of existence.
It is the difference between the piano and the piano player. The piano maybe destroyed and buried but the piano player lives on.
However, when we are physically alive, our minds and brains are interconnected. Live, on stage, they can do great music together. They are so connected that people can have amnesia, in some cases, when their heads are hit very hard by something.
Hit the piano very hard, toppling the musical notes down to the floor, and the piano player will have a hard time playing the piano.
