The bursting of firecrackers on Diwali has deeper roots than festive joy, it’s a continuation of an ancient Vedic tradition. According to the Skanda Purāṇa, lighting up the sky was originally a sacred act meant to honor one’s ancestors.

A verse from the Vaiṣṇava-Khaṇḍa of the Skanda Purāṇa says:
“Ulkāhastā narāḥ kuryuḥ pitṝṇāṃ mārgadarśanam…”
urging people to hold ulkas (firebrands or torches) to illuminate the path for their ancestors, ensuring that even those in darkness (naraka) could find their way.

In Sanskrit, Ulka signifies a blazing torch or meteor, anything luminous that dispels darkness. Scholars like Dr. G.V. Tagare interpret this as an early form of illuminating rituals, much like today’s fireworks. The Ananda Ramayana and other Deepavali-kṛtya texts also mention the Ulka-Dāna ritual, offering light to the souls of the departed.

This practice reflects a spiritual message: lighting the sky symbolizes remembrance, guidance, and the victory of divine light over darkness.

Thus, the modern fireworks that brighten Diwali nights are not merely celebratory, they echo an ancient Purāṇic belief that light connects the living with their ancestors and honors the eternal bond of life beyond.
