Protecting your culture in a foreign land ?

In my recent trip to the US, I got the chance of visiting a temple in a locality there which does not have a huge Indian population. It was a Sunday evening and I saw many people over there dressed in Indian attire and dressing their children in traditional Indian attires as well. I being an agnostic person, wasn't really focused on worshipping the stones rather i spent my time observing people there. It was an overwhelming scene to see parents teaching and asking their children to recite verses of sanskrit shlokas. Those tiny ones could not pronounce a hindi word clearly but their recitation of shlokas was such clear and felt like music to the ears of even an agnostic person like me.

What i liked the most about the scene there was that, even though the parents had decided to settle in a foreign country for better standard of life and better future for their children, but they had not given up their culture rather they were more attached to it than many Indians back in India would be. But again I ask myself how can they justify leaving their motherland for better opportunities and then try desperately to grab on to the Indianess in them by shopping from the Indian groceries and visiting temples often. A question that can be answered in many ways by many people and still be unconvincing.

I was even more touched to see a non-Indian female being accompanied by a Indian lady who was being told the stories of the various Gods and the reason why they were worshipped. She was actually taking interest in everything and also stayed to attend the Aarti and was served with the prasadam. She bowed infront of all gods like any religious Hindu would do.

It feels overwhelming to see people from different cultures finding the Hindu culture intriguing and worth following. At the same time it is saddening to see so many capable Indians giving up everything in india to lead a comfortable life here and fulfill their American Dream. I wish to see more of such genuinely talented people to stay back or at least come back to India and make it a better step by step.
