Adopt a greeting gesture that conveys hospitality. In a Buddhist culture, you might be greeted by people putting their hands together, bowing, and saying "Namaste" which means "the god within me salutes the god within you." Arabs put salt, which cleanses and purifies, before strangers to signal good will toward them.
