Indian civilization has always been about having a balance, an equilibrium with your environment. Philosophically, if you go to the Upanishads, there's the balance between the inside and the outside world, and it is between the Atman and the brahman and the prakriti around you. So that beautiful equilibrium was maintained using a chariot, which will not happen using a jet today, which is guzzling fossil fuels and throwing so much of carbon dioxide emissions into the atmosphere. People, they judge the ancient civilizations using 21st century glasses again, as I started, you have to have an open mind. And just because they did not have cars or fossil fuels does not mean they did not have technology.
