Tilaka is a special kind of mark that some people put on their forehead as part of their religion or traditions. Think of it like a sticker that you put on your forehead, but it's made out of special ingredients like sandalwood paste or clay.
People who practice Hinduism, Buddhism, or Jainism often wear tilaka to show devotion or respect to their gods or spiritual teachers. It can be a simple dot, a line, or a more complex design, and it comes in different colors depending on the occasion and the person's beliefs.
Putting on tilaka is like saying "hey, I'm proud of my beliefs and I want to show it!" It can also be used for special events or ceremonies, like weddings or religious festivals.
So, in short, tilaka is a type of mark that is worn on the forehead to show religious devotion or respect, and it can be made of different materials and designs depending on the occasion and belief system.
