Decorated lights decked up buildings and earthen lamps dotted houses as people across the country celebrated Diwali on Sunday with much fanfare amid some restrictions on bursting of firecrackers imposed by the Supreme Court.
People exchanged sweets and gifts, visited temples and greeted each other, with many of them taking the virtual route to convey their wishes.
There was, however, no traditional exchange of sweets with Pakistani soldiers along the International Border (IB) and Line of Control (LoC) in Jammu and Kashmir or the Indo-Pak border in Punjab, officials said.
President Ram Nath Kovind greeted the people of the country and urged them to "try to bring happiness in the lives of those who are less fortunate and needy by lighting the lamp of love, care and sharing".
Vice President M Venkaiah Naidu also extended Diwali wishes to the people. Prime Minister Narendra Modi hoped that this festival brightens everyone's "lives with prosperity and good health" and there is "happiness all around".
The Golden Temple in Amritsar was illuminated with a newly-installed special lighting system and traditional 'diyas'. It witnessed a huge rush of devotees who took a dip in its holy tank and offered prayers at the sanctum sanctorum and Akal Takht (highest Sikh temporal seat).
The task force of the Shriomani Gurdwara Parbandhak Committee was also deployed in the periphery of the Golden Temple.
'Langar' (community kitchen) arrangements were made for devotees who will stay in the temple all through Diwali night.
Like previous years, Modi celebrated Diwali with soldiers. This time it was in Jammu and Kashmir's border district of Rajouri. He praised them for their valour, saying it enables the government to take decisions hitherto considered impossible.
He said everyone wants to celebrate Diwali with their family and so he too travelled to be with his family, which is the "brave jawans of the armed forces".
Wearing a combat jacket, Modi exchanged wishes and sweets during his nearly two-hour-long stay and interaction with the troops deployed along the LoC.
In Delhi, people started bursting crackers in some areas much before the Supreme Court-set two-hour window.
With Delhi's air quality plummeting to dangerous levels around Diwali every year, the Supreme Court in 2018 banned polluting firecrackers and ordered that only green firecrackers, which is said to cause 30 per cent less pollution, can be manufactured and sold.
But the green pyrotechnics have failed to draw good response both from sellers and buyers, primarily due to lack of variety, limited stock and high prices.
Last year also, people continued to buy the conventional firecrackers and use them.
The Arvind Kejriwal government has organised a four-day mega laser show since Saturday at Connaught Place to encourage people shun crackers to cut down pollution in the national capital.
