Lalu Yadav today offered some advice, unsolicited of course, to Prime Minister Narenda Modi who announced a 1.25 lakh crore rupee mega package for Bihar yesterday. "My advice to Modiji is that he must not shout too much, else he may burst a vein," said Mr Yadav, a former Bihar chief minister, on stage at a public function at Patna's Sri Krishna Memorial Hall.
