The Mysterious Being called 'Man'- nara namanav

     All the animals, including the human beings are endowed with nervous system that convey emotions, energy, air and water, enable blood flow, and communicate with organs. Man is called nar manv. However, we have not understood the development of the nervous systems and their function fully enough to organize them to perform efficiently. Yoga helps in this direction.
 The role of   nerves and neurons in the life of a jiva is of utmost importance. Every Cell is interconnected with each other intimately conversing with each other and sending communication to the brain cells.  The cells themselves do not move, but just push and pull each other. These gross as well as subtle communication system called the nadis, neurons and nerves constitute the mainstay of the jiva. One cannot imagine what would be the fate of the jiva without an efficient networks system constantly working in the body and each cell charged with energy!

    The information stored in the trillion and odd brain cells cannot be even imagined by mortals. A pin-head of a cell stores the knowledge available in all the books of the world libraries! Each cell has an intricate structure that will be discussed in detail later. The most important components of a cell are the amino acids, vitamins, enzymes, protein cell membrane, the chromosomes and the genes, the DNA, RNA and the like.

 The role of nerves and neurons in our body are akin to the transport and communication network, and mostly a wireless system! These may be compared to the circuit system in a computer. The energy flow in the computer and the hardware decide the function depending on the software provided and the function for which the computer is devised. Unlike a computer the human system functions with an invisible strong force of thoughts, desires, dreams, imagination, images and resolves and use the brain as a CPU! The software is constantly devised from the beginning to end of a jiva and the source of the energy supply here is a constant one.

   Human perception of objects is a very complex phenomenon and it depends on a number of extraneous factors that govern the quality and appearance of the objects, as well as, the internal mechanism of the senses and the brain as dictated by unknown factors such as mind, desire, impressions and memories, dreams and aspirations, etc. In fact nothing exists as long as the mind does not exercise its desire and focused attention on the desired object. Here, the captive power, fascinating qualities of the objects that attract the senses and the mind cannot be ignored. Brain, as a machine that classifies and clarifies the objects, has different domains that exercises visual stimulations. The brain waves, such as, the alpha, beta, theta, and delta have different powers. The overall mental coordination and learning are the functions of the alpha brain waves. The beta brain waves are generated when there is alertness focused attention, interest in solving a problem, or taking a decision.  The theta and delta brain waves are of low frequency and operate when the person is asleep, or in deep meditation. The gamma brain waves are the highest frequency brain waves capable of tackling several issues simultaneously and processing information coming from different areas or parts of the brain. It is here we find the perceptions, feelings, and word formations occur! There are fluctuations in the brain waves that cause many serious problems like delirium, autism, schizophrenia, and many neuropsychiatric disorders. There is need for further detailed study in this field.  rvous system plays a very important role in the life of all animals including man. The function of the cells that create and maintain this wonderful network needs a careful study.
