We do have very deep, diversified religion/language and customs but there are many basic similarities in all the regions. In cooking, we use the same ingredients but in different proportions among the states in the South. We need to read the history of each state to understand its traditions and culture. In South, especially Tamil Nadu, people actually worshipped nature more than idols in the ancient past. We have chithargal, saints/men who lived worshiping nature. It is at the advent of Aryan culture that idols were started to be worshipped. Recent excavations have proved this. We worship Muruga, brother of Ganpathy, second son to Lord Shiva and Parvathi but He is not worshipped in the North. And Holi is celebrated by people from North who live here. Mehendi and sangeet were never in our wedding functions but they are included now with the mix up of cultures now with different state people living together.
Instead of travelling abroad, people need to travel to each state and enjoy India's rich culture and heritage with mutual respect. We will have so many interesting things to learn from each other. That is why being national oriented is so important now.
Sorry for the long post.
