Siliguri/ Kanpur, Oct 15 (ANI): With cheaper lighting options flooding the markets, Indian potters complain of slack in the sales of their traditional terracotta 'diyas' or earthen lamps ahead of Diwali, the festival of lights. In recent years, Chinese fairy lights and electric lamps and other similar alternatives to handmade lamps have entered Indian markets, giving fierce competition to the indigenous pottery industry. Potters in a village in Siliguri city of West Bengal complained that their sales have gone down. Repeated complaints to the village council were in vain. The potters do not receive any help from the government either. The major advantage of electric lights is that they are more durable than terracotta diyas, which may break after one use and need constant oil refills which add to their cost. Diwali, which will fall on October 23 this year, is celebrated with great fervour and gaiety all over India as it marks the return of Hindu god Lord Rama to Ayodhya after he defeated Ravana, the powerful king of Lanka.
