The Janeu is a sacred thread worn by Hindu males, symbolizing their initiation into the Brahmin community or other Hindu castes. It is typically made of cotton and is draped over the left shoulder, crossing the chest. The ceremony of receiving the Janeu, known as Upanayana, marks a significant rite of passage, often occurring during childhood. The Janeu represents spiritual purity and the responsibilities of adulthood. It is believed to connect the wearer to their ancestors and the divine. The thread is also associated with various rituals and is often replaced or renewed during important life events, emphasizing its ongoing significance in a person's spiritual journey.
