Trust Prime Minister Narendra Modi to catch the pulse of his audience. On Monday, he laid the foundation stone for a national memorial in New Delhi to Dalit icon and the architect of the Constitution B R Ambedkar. Modi also delivered the Ambedkar Memorial Lecture. As he walked to the lectern to deliver his speech, many in the audience shouted slogans of "Modi zindabad" (long live Modi) and "Bharat Mata ki Jai" (victory to Mother India). But the PM began his speech by raising the slogan, "Jai Bhim" thrice and asked the gathering to do the same. "Jai Bhim", or victory to the vision of Ambedkar, is a slogan to acknowledge his contribution to the cause of the Dalits.
