Scientific development in a country is a continuous phenomenon. Quest and inquiries have to come from within, it cannot be artificially created as it needs mental freedom to capture new ideas-basis of inventions and discoveries. Science and arts can develop well only with social and economic security. Impoverished souls cannot devote time and energy on ideas and thoughts other than how to fill their belly. At the same time a nation becomes stagnant when there is no external threat for centuries, and that may have been the reason of decline of great powers in the history of mankind. Scientists cannot, and should not suffer from egoistic attitude, subjectivity, and self-held beliefs. Enquiry is basic to scientific development and nothing should be accepted unless proved on predetermined parameters. At the same time scientists, at times have to go against accepted social and religious norm and beliefs, and they should not shy away. There are many instances in the history of social developments where scientists have been ridiculed and subjected to harassment and ignobility. But that should not deter a scientist from the quest he may have embarked upon. Scientific development needs temporal support without which it may be difficult and time consuming. Scientific development also has to be timely and contemporary as required. Development is relative to need of the time, and of course to what extent can it be useful to the mankind in his journey to the ultimate. In this part I have discussed ancient scientific wisdom in India, dormant medieval period, and revival, if not composite at least in certain areas, and have pointed out weakness in the system.
