Namaste works everywhere
Palms together, slight bow. It works across religions, regions, and social situations. It's respectful, warm, and universally understood.
Tip: Touching elders' feet is a sign of deep respect. You'll see younger people doing this — it's a beautiful gesture.
Remove shoes often
Shoes come off at temples, mosques, many homes, and some shops. Wear easy-on, easy-off footwear. Pointing feet at people or religious objects is disrespectful.
Hospitality is overwhelming
Guests are treated as divine ('Atithi Devo Bhava'). Expect to be offered tea, food, and more food. Refusing too firmly is impolite. Accept at least something — even a small portion.
