Brain is an organ like our hands and legs. It is our inner organ in the skull for our thinking purpose. Its work is pure thinking. To everybody in the world, from birth to death, the total brain won't function totally. That is why its branded as an organ. To all of us a portion of the brain is always functioning from birth to death. This functioning portion of the brain is called as the mind of a man. The mind's capacity is limited. The capacity of the brain is full. This is the difference between the mind and the brain. Chittta : Intellect is called the chitta of a man.
