What is the significance of the festival of Diwali in Hinduism?

The festival of Diwali holds great significance in Hinduism primarily as a celebration that symbolizes the victory of light over darkness, good over evil, and knowledge over ignorance. This theme is illustrated in various Hindu epics and texts, most notably in the story of Lord Rama's return to Ayodhya after defeating the demon king Ravana, which is marked by the lighting of lamps to welcome him home. The act of lighting lamps serves as a powerful metaphor for the dispelling of ignorance and the emergence of knowledge and righteousness in the world.

Diwali also encompasses various rituals and practices that reinforce these values, such as the lighting of diyas (oil lamps), fireworks, and the decoration of homes, which together create an atmosphere of joy and positivity. This festival emphasizes the importance of inner illumination and the pursuit of a good life, making the symbolism of light central to the celebration.

While the other options touch on aspects of cultural practices and seasonal changes, they do not capture the core essence of Diwali as closely as the theme of light triumphing over darkness, which is foundational to its celebration in Hinduism.
