INDIA, November 5, 2012 (boldsky.com, by Anwesha): There are many reasons for which Diwali is one of the few pan-Indian festivals. Almost all of India celebrates Diwali but their myths and rituals for this festival are different. Here are few reason of why we celebrate Diwali:
1. Ram Returns To Ayodhya: In most of Northern India, Diwali celebrations mark the triumphant return of Lord Ram to his homeland Ayodhya.
2. Lakshmi Puja: The most important rite of Diwali is the Lakshmi and Ganesh puja. This puja is done on the darkest night of the year, that is the no moon day of Ashwin maas (a month of the lunar calendar).
3. The New Year: For Indian businessmen, Diwali is the starting of the new financial year. They close their books for the last year and begin new books on this day.
4. Kali Puja: In Bengal, Odisha and some parts of Bihar, Mahakali or Nishi puja is celebrated on the night of Diwali.
5. Guru Nanak: Not only Hindus but Sikhs too celebrate Diwali. This is because, on this day Guru Hargobind Ji, the sixth guru of the Sikhs was released from prison along with 62 Hindu kings.
6. Lord Mahavira: Many people believe that Lord Mahavira attained his moksha or nirvana on the 15th of October which is roughly the time around which Diwali is celebrated.
7. The Light Of Hope: A deeper spiritual meaning of Diwali comes from the fact that it is the darkest night of the year. So, to dispel the darkness of ignorance and hopelessness, people light diyas on Diwali.
