This symbol is very similar to the Bindi. It is a mark on the forehead. The Tilak for a man is a straight line and a dot for a woman. The slight differences in lines or dots help distinguish between the different sects of Hinduism. The Tilak is made out of clay or ash, which give many of them a reddish color. The Tilak is applied everyday to very serious Hindus. All Hindus wear a Tilak whenever they visit a temple (even non-Hindus are given one when they visit a temple) and on special religions ceremonies (weddings). The mixture that the Tilak is made from cools the forehead and helps mediation for it makes one more focused.
