Raja Raja Cholan, a great king in Chola dynasty. He ruled south India during period of 985–1014. Cholas determined to conquer whole south India and did it. The other dynasty which ruled south India is Cheras and pandyas. Cheras were people belong to the west side and pandyas to the east. These kings always fight each other. In the beginning the Cheras were ruling the whole south India and they loss power to Cholas and after Cholas pandyas ruled the south India.
During this period they build many temples. All those were rich in architecture. Kings order to build big temple to create job opportunity. So no famine occurs in their state. But why they didn’t invest their time in research activities like time machine, immortal life, nuclear bombs and more useless things. There were millions and millions of people lived in this world before 16th century. Whether we can assume that no people have thought about these things.
They would have. But why didn’t they continued their dreams and make them happen?
Old people were visionaries. They brought some new things to the society when it had no more harmful to people or they saw entire impact of the new idea on human society. These computers would idea of old people but they didn’t bring them to society. Old people know that people would suffer with its impact. Old people ran behind sentiments which keep them happy. They ran behind spiritual things so they can be happy.
But we run behind money and worries run behind us. Run behind family, so worries run away from you.
