Chhaya, meaning "shadow" in Hindi, refers to the dark shape produced when an object blocks light. Shadows can vary in size and intensity depending on the light source and the object's distance from it. They are commonly observed during the day when sunlight casts shadows of trees, buildings, and people. In many cultures, including Indian traditions, Chhaya symbolizes protection and comfort. It is often associated with the idea of a guardian or a presence that follows and supports an individual. This concept can be seen in various art forms, literature, and folklore, where shadows represent both mystery and companionship.
