Every human being is a part of Nature, fully equipped with all potentials physically and mentally to realize the purpose of his being. One is born and then grows, perceives the beauties and mysteries of the universe, enjoys, suffers and dies. Between these two nodes of birth and death, man experiences pain, pleasure, peace, satisfaction and ecstasy in life. The accumulated storehouse of experiences constitutes culture, which is carried over generation to generation from the primitive age to the present. When this accumulated knowledge and hence the awareness increases further and further, a time comes when the mind desires to know its origin, capability and the ultimate goal. This desire is the cause for all exploration.
