What is mind and its construction

What is mind???? we can say hey buddy that is a very simple question how dare u ask it over the web???? Well friends then I would say yes its a very simple question but not stupid. How many of us know what is mind and how it works..........Some Doctors define it "The afferent nerves bring the sensations from the periphery or extremities of the spinal cord. The sensations then pass to the medulla oblongata at the back of the head, where the fibres decussate. From there, they pass on to the superior frontal gyrus or superior frontal convolution of the brain in the forehead, the supposed seat of the intellect or mind. The mind feels the sensations and sends motor impulses through the afferent nerves to the extremities - hands, legs, etc" like this in some biological term well then how I know is that this much is the biology I have learnt from my schooling........... I am serious men anyways. Brain is different , mind is different and soul is different but they have one comman things they are all found in this beautiful human body. That is indeed fascinating isn't it...Now lets find out how its ....
The Mind doesn't have any structure its like a link/transaltor/protocol etc what we can call in human intellectual terminology. We have the physical body, brain, mind ,etc.... Here the brain is that part of mind which gives us the consciouness about our physical existence and another part of mind which gives us awarness and consciouness about our inner self. THIS can is explained in vedas as Mulavidhya and Tulavidhya; where Tulavidhya stands for minds ability to learn and explore empherical objects and information where as Mulavidhya stands for minds ability to learn and explore the casual ignorance that is the knowledge about your real self the ATMAN or Soul.
