FHere are some guidelines to follow during your stay in India:
Dress modestly. Women, in particular, should avoid revealing clothing. This means no sleeveless or low-cut shirts or tank tops, and no shorts. Make sure your knees are covered.
In many Hindu temples, non-Hindus are not allowed to walk inside certain parts of the temple complex.
If you are invited to someone’s home, it is customary to bring a small gift such as a box of sweets
Don’t feel offended if you are asked personal questions, such as “How much do you earn?” “Are you married?” or “Do you have kids?”
Maintain silence, avoid loud talking, and refrain from touching idols.
