A mark worn in India
The bindi is a circular mark or dot worn on the forehead. It can be in many different sizes and many different colors. The word 'bindi' comes from the Sanstrit word 'bindu' which means "a drop or small dot or particle." There are rules about who wears what bindi but most people don't follow them anymore.
Both men and women can wear bindis. Mostly women wear them though and you can wear them weather you're married or not. The married women are to wear the red bindi. Never black though. People also wear body decorations with them like jewels.
In ancient times the bindi was worn for religious reasons. Now it is worn for manly decoration. It is still apart of the Indian tradition today.
