In the week leading up to Ram Lalla's historic Pran pratishtha in Ayodhya, the Prime Minister is adhering to a 11-day 'Yam Niyam anushthan', living a life of austerity to welcome Lord Ram as per the scriptures. As a part of this religious exercise, the PM has been sleeping on the floor and drinking only coconut water, say sources. Over the last week, PM has visited a number of temples connected to Lord Ram across the country.
