A computer required hardware to perform its function. And the hardware needs software to make it run. Without software, hardware would be useless and without hardware, software can not be used. Brain is like the hardware and mind is like the software. But in reality, the difference between brain and mind are more complicated than software and hardware.
Sometimes we use the words brain and mind interchangeably even though they really do refer to separate, although often overlapping, concepts. The brain is an organ but the mind isn’t. The brain is the physical place where the mind resides. It is a vessel in which the electronic impulses that create thought are contained. With the brain you coordinate your moves, your organism, and your activities and transmit impulses. But you use the mind to think. You can muse at what happened, what is scheduled and what maybe will happen.
The mind is the manifestations of thought, perception, emotion, determination, memory and imagination that take place within the brain. Mind is often used to refer especially to the thought processes of reason. The mind is the awareness of consciousness we know, the ability to control what we do, and know what we are doing and why. It is the ability to understand. Animal are able to interpret their environments, but not understand them. whereas human are able to understand what happens around them, even if not the scientific reasoning for it, and therefore adapt.
The mind made humans capable to solve complex logical problem which differentiates us than other living beings. Logic makes us understand that things are not as what they seem. Our ability to analyze situation makes it possible to develop solutions to problems and lead us toward practical solutions. We may not be able to see in the ultraviolet range, but we may design instruments to do so. We may not be able to see atoms, but we can design experiments that enable us to know their properties. Each stage of scientific advancement has usually been made by trying to reach a logical conclusion consistent with our observations. We no longer believe in demons as the cause of disease. We now believe in viruses, bacteria, genetic defects, and environmental pollution as the real causes of disease. Our irrational and unfounded “superstitions” have given way to “knowledge”.
Brain only gives directives. Decisions, choices, judging, ideas all happen in the mind, and mind can tire you out, make you run around in circles, make you restless and its ideas and thoughts have undercurrents.
Brain directives are accurate. It flashes messages and directives without any undercurrents.
Mind has its uses. It can act as a watch dog to ensure that nothing undesirable seeps into your system, and your system stays virus free.
Also, according to worldly norms, mind can compile, store, organize and polish raw knowledge or unorganized flow of thoughts that comes from the brain. Like Supreme Intelligence uses the panchbhutas, five elements which are in raw state to create human body, a beautiful form, similarly, mind is there to compile, organize and give beautiful form to knowledge, thoughts flowing through the brain so they are acceptable to others’ mind.
