With the aid of science we had built mighty civilizations thousands of years ago when most people in Europe (except in Greece and Rome) were living in forests. We had made outstanding scientific discoveries e. g. decimal system in mathematics, plastic surgery in medicine, etc. However, we subsequently took to the unscientific path of superstitions and empty rituals, which has led us to disaster. The way out of the present morass is to go back again to the path shown by our scientific ancestors, the path of Aryabhatta and Brahmagupta, Sushrut and Charak, Panini and Patanjali, Ramanujan and Raman.
