Addressing a Town hall event at Siri Fort auditorium here on the third and final day of his visit to India, Obama lauded Milkha and Mary Kom among others as achievers, while making a point that courage and humanitarian values unify both the nations.
Milkha said "those who live for the good of the country and those who bring laurels to the country always remain in the hearts of people".
"It is all the more heartening that it came from an inspiring person like him. His grandfather worked as a cook and he is from a humble background who rose to such a high position. It is certainly something I will cherish," said octogenarian Milkha, who missed a 400m bronze medal by a whisker in 1960 Rome Olympics.
"It is an achievement for our Prime Minister that Obama came to India for the second time and that also to grace the Republic Day Parade," Milkha said.
