Diwali, according to the lunisolar Hindu calendar, is celebrated on the full-moon night between mid-October and mid-November. Also known as the 'Festival of Lights', Diwali is celebrated by the lighting of traditional clay lamps (diyas) and bursting fireworks. Although everybody celebrates the festival, sadly, not everyone is aware of the true significance of this holy festival.
The return of Lord Rama, after 14 years of 'vanvaas' (banishment), to the city of Ayodhya was celebrated by the lighting of 'diyas' - hence the name 'The Festival of Lights'. However, the spiritual significance of Diwali is the triumph of good over evil. Literally, this is portrayed through the slaying of Ravan by Lord Rama. This symbolically refers to the light of knowledge expelling ignorance which leads to knowledge of the oneness of everything. Diwali, in fact, is celebration of this self-enlightenment.
