I think that with the advent of electricity, many things got changed dramatically. Nowadays, we cannot imagine living without electricity which not only lights our houses but provides power to run air cooler, AC, TV, geyser, heater, oven, mixer-grinder, electric bell, modem for broadband connection, computer and what not? Funnily enough, just imagine that there was no electricity in the palaces of Ashoka, Shahjehan, Vikramaditya, Krishna or Pulakesin.
We are gradually becoming dependent on external resources. We first take outside junk food to get sick and then take medicine to get normal. We have spoiled natural balance by disturbing the natural ecological balance resulting in pollution and inclement weather conditions.
Let us encourage each other in sharing knowledge.
