Not only women, but Hindu men also wear a dot on the forehead, indicating their third eye. The pottu is a very auspicious symbol, reminding those who ear it of their spiritual heritage and ideals, wherever they may be. It also serves to identify a Hindu among the members of all other religions. Muslim girls often cover their face with a veil. Christian girls wear a cross.
Jewish boys wear small leather cases holding scriptural passages.
Men and women of a particular faith often wish to identify themselves to each other, and they do so by wearing religious symbols which generally are blessed in their temples, churches and synagogues. In many cases a dot on the Hindu woman's forehead is similar to a beauty mark, just as European women used to wear a black dot on their cheek as a beauty mark. An unmarried girl wears a black dot, and a married girl a red one. Nowadays the dot's color complements the color of a lady's sari. Wearing a dot on the forehead is largely a cultural symbol or a beauty symbol.
