A day after linking the ongoing pan-India march of the Congress, the 'Bharat Jodo Yatra', to the epic Ramayana, and party leader Rahul Gandhi to Lord Ram, Congress leader and former Union minister Salman Khurshid today said it was a metaphor. "Our country has a culture, a thought. We name so many children after Lord Ram. Why do we do it? We never heard any child named Rahim, but we have heard Ram. Those we expect to do good work, walk the right path and also guide others to it, we name them after those we respect and revere. You know what idioms and metaphors are," he said.
