Our skull has been filled with grey matter called the brain. This brain forms the most accurate and exact system of our body because it commands all of the powers of our body and it manages all of the organs of our system.

In order to understand the importance of this great center, it would be a good idea for us to explain the following for you.

The newspapers had printed that a Shiraz university student in Khuzistan was in an automobile accident and his brain was damaged but it seemed that nothing at all had happened to him. All of his organs were healthy but strangely enough, he had forgotten all of his past life. His mind worked well. He could study but if he saw his mother and father, he did not recognize them. When they said to him that this was his mother, he was surprised. They took him to his home in Shiraz. They showed him the handicraft work he had done and then hung on the walls of his room.

But he looked at it all in amazement and said that he was seeing these things for the first time.

It became clear that in the brain damage he suffered, cells which were, in reality, transitions between thought and his memory were no longer working and like a blown out fuse which cuts off the electricity and brings darkness, his memory of the past had been disconnected.

Perhaps the point which no longer works is no bigger than the size of the top of a pin but what an effect it has had upon his life and from this it becomes clear how complicated and how important our brain is.

Our brain consists of two separate parts: first, the part which is controlled by our voluntary which controls all of our voluntary motions like walking, looking, speaking. Second, the involuntary part which controls the movement of our heart, stomach, etc. and if one part of this part of the brain does not function, the heart or another organ will no longer function.
