Deepawali or Diwali is certainly the biggest and the brightest of all Hindu festivals. It's the festival of lights (deep = light and avali = a row i.e., a row of lights) that's marked by four days of celebration, which literally illumines the country with its brilliance, and dazzles all with its joy.
Each of the four days in the festival of Diwali is separated by a different tradition, but what remains true and constant is the celebration of life, its enjoyment and goodness.
According to my friend Rajeev, the fireworks are off the hook. And, he says, you'll have a great view from your terrace.
Historically, the origin of Diwali can be traced back to ancient India, when it was probably an important harvest festival. However, there are various legends pointing to the origin of Diwali or 'Deepawali.' Some believe it to be the celebration of the marriage of Lakshmi with Lord Vishnu. Whereas in Bengal the festival is dedicated to the worship of Mother Kali, the dark goddess of strength. Lord Ganesha, the elephant-headed God, the symbol of auspiciousness and wisdom, is also worshiped in most Hindu homes on this day. In Jainism, Deepawali has an added significance to the great event of Lord Mahavira attaining the eternal bliss of nirvana. Diwali also commemorates the return of Lord Rama along with Sita and Lakshman from his fourteen year long exile and vanquishing the demon-king Ravana. In joyous celebration of the return of their king, the people of Ayodhya, the Capital of Rama, illuminated the kingdom with earthen diyas (oil lamps) and burst crackers. Read more about Diwali here
