Indian culture may be hard to grasp for people from other countries, except Californians and drunk street salesmen from Barcelona. Most countries keep themselves with a national mainstream culture, a daft upper class high culture and a lot of misfit outbursts called subcultures. India needs no more than a few blocks around your tourist Hotel at Connaught Place to cover that part. If you dare to go further away to see something more, remember to wear a mental helmet of etnocentric bigotry to protect yourself from whatever is going on, or you might easily find your self drowning, like generations of intruders before you, in the Indian vortex of continously expanding cultural confusion.
