Can you lift your arm with your mind? With nothing but your desire?
If so your mind is a mechanism that can make the brain do certain things.
And one day possibly we will understand how.
No, you cannot lift your arm with your mind. Your physical brain generates a signal that you (only sometimes experience as a desire to lift your arm). That brain state set off a chain of physical reactions that lead to the muscles contracting and flexing in a way that lifts your arm. Your "mind" isn't causing anything. It is an effect of some of the brain states involved in causing your arm to move.
The mind, a desire, starts the process.
And the mind uses its slave, the brain, to do it.
Try it. Just "tell" your arm to move with your mind and it will.
