Diya’s denotes the purity, goodness, power, and good luck. The lighting of Diya means eliminating the darkness and evil powers at home. Diya’s lighting is very important during Diwali because it is celebrated on the new moon day, where there is pure darkness everywhere, to remove that darkness people light Diya’s. The lighting of Diya provides joy and hope. The Diya light denotes both the Atma and Paramatma.
