Structure and Composition of the Jiva

  The Earth is called a 'Living Planet' for it supports life. It is not clear whether any other planet hosts life or not. However, it is certainly clear about what supports life.  Life or jiva is a biological entity, It is sustained by air, food and water. Thus, wherever air, food and water are available there is the possibility of formation of life.

    Now, what is life? This question is not easy to answer for it has several shades of meanings. Some think just living is life, whereas, some think there is something beyond just living! Life is, interestingly, Energy, Force, Intelligence and Light (L I F E). The motive power behind all living beings, jivas, is the Energy factor. It comes from Light (of the Sun). Life is essentially a by-product of food produced by sunlight. Food is created by a combination of elements and compounds and the jiva manifests from food! A little soil, moisture and light are enough to create miniature life forms.  The Viruses and germs that abound in atmosphere are very powerful physio-chemical entities that turn biological! Thus, chemistry is involved in creation of biological entities. The Ribose and the DNA are the basic factors in creation of jiva. There are hosts of proteins (almost 77 000!), enzymes, amino acids, vitamins, genes, harmons and chromosomes that go to build cells, which in turn construct tissues and organs of the jivas. The most intriguing factor of the jiva is the cell formation, cell division and cell  function. One single Cell can perform almost 60 000 functions in a fraction of a second! The same cell does different functions in different organs created by itself by permutation and combination. Just like a person performs different functions in family, society, and community, the same cell does the functions of creation, sustenance, development and dissolution. The cells constantly die out and create new ones and transfer all memory before they die out! The ageing process that depends on the cells development is a mystery yet to be solved! The number of cells in a jiva cannot be measured. There are a trillion cells in the brain of man! Each cell is a mini universe!
   Thus, the cell biology and genetics holds the clue in future of mankind on this planet.
