The Mind & Brain are totally different entities.
The Brain is a computer processor.
In order to function, the brain requires the power of electricity, the authority of an operating system and the ability of a downloaded programme.
My downloaded programmes are the sum total of my life experiences to date.
My electrical life-force is present from my conception and birth till I die.
My operating system is supplied by my Mind.
My Mind is the computer operator.
My Mind created the computer and the physical body that it is designed to operate.
My Brain operates my body.
My Mind operates my brain.
It is not possible to perceive the entirety of the Mind from the perspective of its conscious aspect alone.
I am conscious of my body and my brain, yet I am not aware of the Consciousness that is my Mind.
My Mind is conscious of its Self.
My Self is not aware of its Mind.
