Explanation
In India, the head is considered the seat of the soul and a sacred part of the body, so patting someone on the head—especially a child or an adult—can be seen as condescending or intrusive. This is rooted in Hindu beliefs and general social norms that emphasize respect for personal space and hierarchy. Even with close friends, it's safer to avoid this gesture unless you are certain of the relationship.
Local Tip
Instead of patting the head, offer a respectful namaste with palms together or a light touch on the shoulder if appropriate.
