Human mind is a complex organ. It has a great power to receive the information, to store and process the data and send instructions to act as per the needs of the body part or organ for action. For example, there is a simple prick on the finger, the information is sent to the higher centers, it is interpreted and the information is sent via the motor nervous system that the finger be removed from the site of prick. If required the order is given to the other parts of the body to assist in this task. This is one simple mechanism.
Thus there are three types of such systems namely:
1 The Sympathetic Nervous System
2 The Para Sympathetic Nervous System
3 The Autonomic Nervous System
Besides these there is spinal cord, which works by spinal reflex action. The higher centers may or may not be involved. The autonomic nervous system is not in the control of the body. Thus the beating of the heart is normally done independently. But the environmental factors such as shock, fear etc. can alter the physiological functions such as rate, rhythm etc.
There are various chemicals such as adrenaline, acetylcholine etc. that play a vital role in performing the brain functions. Then there are elements like sodium, potassium, calcium etc. The various brain functions can be controlled by the living beings. Certain hormones also play a great role in execution of an action.
This is a brief knowledge of the brain and the nervous system. But besides this the brain has a tremendous power. The complete knowledge of brain power and functions is not known to humans today. Probably the ancient Hindus had the knowledge of these powers .Genetics and so the hereditary plays an important role in human behavior. Reaction time for an action differs from human to human. The term Mind set is used where the human being prepares him/herself for an action that he/she performs or intends to perform against an action or environment.
There is an old proverb, “Practice makes a man perfect”. This practice can be in accordance with self experience or training. Say for example, one has to prepare for an examination or a competition then it is mandatory that one should have sufficient reason to perform the task. There are three Ws that one should answer. Why a certain task has to be performed? How can it be done? When should it be done?
