Prime Minister Narendra Modi on Friday said the nation's heritage is common to all and it cannot be divided based on political affiliations.He was speaking here at the birth centenary of late Congress leader Girdhari Lal Dogra, who was Finance Minister Arun Jaitley's father-in-law."The heritage of the country is common to all of us and it cannot be divided into compartments because of political considerations," Modi said, paying his tributes.He said the late leader worked for the country, irrespective of which political party of ideology he adhered to.In a lighter vein, Modi said the Congress leader must have had a great understanding of human beings and "that is why he chose a son-in-law like Arun Jaitley".He said that despite being the son-in-law of the late Congress leader, Jaitley held on to his own political beliefs and never used his father-in-law's clout."Otherwise we all know what embarrassment sons-in-law have become for their in-laws nowadays," said Modi, taking a dig at Congress president Sonia Gandhi's son-in-law Robert Vadra. He didn't name Robert Vadra.Modi also greeted Muslims on the eve of Eid. He then left for New Delhi.
