Not long ago, the ‘Ram Ram’ chant was only limited to morning greetings to friends, family and acquaintances in the northern parts of India, where Hindu traditions have largely been Ram-centric. It was a harmless, docile and lovable phrase used mostly by Hindi-speaking folks.
Even in that same space, delineated by Hindi as the main language, in Mathura, for example, as projected by individuals representing that area, people wish each other saying ‘Radhey Radhey’.
In my part of the country, Southeast India, we would normally wish friends with a smile and folded hands saying ‘Namaskar’ (definitely not a ‘Namastey’). A Tamilian would say ‘Vanakkam’ in the same vein. This just goes to show how diverse we Indians are, even in such simple daily acts.
