How did the Caste system provide a sense of order in India?
yuradex [85]
The caste system regulated many aspects of live, such as what jobs one would have, whom one could marry and the position in the society.

These were taken to be almost impossible to change and they made the society less flexible, with less changes. People didn't see much change nor did they expect many changes, and this stability gave a sense of order.
