Deepawali festival was celebrated with diyas in past but gradually people changed this trend and now instead of diyas only electrical ladis,lightning & fire crackers are used. People for their convenience market & sale created all this. It decreases the importance of this day. This day becomes the most polluted day due to fire crackers. In realty there is no use of fire crackers to celebrate deepawali. Rather it creates many health problems. Right way to celebrate dipawali is cleanliness & prayer to lord Ram-Sita.
