This is one of the few mythological significance of Diwalii. The historical significance is: "Once, in Lord Krśńa's absence, a neighboring king, Narakasura, attacked Dwaraka, Krśńa's capital. (By the way, the Dwaraka of Krśńa's time is no more. It long since became submerged under the Arabian sea. The old city of Dwaraka is sleeping under the Arabian sea: I would say about twenty-six miles west of the present-day Dwaraka). Immediately after Narakasura attacked Dwaraka, Satyabhámá (one of the three wifes of Lord Krśńa) she was in charge of defending the kingdom and lost no time and launched a fierce counterattack against the invading forces. Narakasura's army was defeated and he died on the battlefield. The day Narakasura was killed was the day before the new-moon day of the month of Karttik [mid-October to mid-November]. The whole city of Dwaraka was transported with joy. They jubilantly celebrated by lighting fourteen candles and, on the following evening, worshiped Satyabhámá with festivities and diipávalii [elaborate lights]" Shrii Shrii Anandamurti - Awakening of the woman
