New Delhi: Prime Minister Narendra Modi on Thursday paid his tributes to B.R. Ambedkar, the chief architect of India's Constitution, on his 125th birth anniversary, saying “his economic vision was unique”. "On his jayanti, I bow to the venerable Babasaheb Ambedkar. Jai Bhim. He is a 'vishwa manav' who devoted his life in service of the poor and marginalised," the prime minister said on Twitter. "He believed in the power of education. His economic vision was unique, with a strong emphasis on welfare of the farmer as well as the worker," he added. Born on April 14, 1891 to Bhimabai Sakpal and Ramji in Madhya Pradesh, Ambedkar died on December 6, 1956. Prime Minister Modi will participate in a function to be held in Madhya Pradesh's Mhow city in connection with Ambedkar's 125 birth anniversary celebrations and launch the nationwide 'Gram Uday se Bharat Uday' campaign later in the day.
