I was in Mumbai two years back and found the city gentrified and awashed with wealth. Bangalore had exploded with development and become very chaotic. And that's true of India as a whole. It is coming to terms with explosive development while trying to keep its soul. What's good about India is that it is attached to its past, its buildings. Unlike China, which doesn't pay much attention to its heritage.
One of the rewarding things about coming back to India is that it hasn't changed substantially. It's eternal, and this is true of both its glories as well as the horrors. It's one country which is as hospitable as ever. It doesn't stop anyone from coming here. Unfortunately, this is not true of all places. For instance, countries like Iran and Afghanistan have become totally inaccessible. That's very sad.
