NEW DELHI: Prime Minister Narendra Modi gave a peep into his early days as a swyamsevak on Sunday, saying how he learnt the difference between a successful and a meaningful life. At the birth centenary celebrations of Eknath Ranade, RSS leader who founded the Vivekananda Kendra, Modi said it was from him that he learnt the importance of a "sarthak" (meaningful) life, not merely a "safal" (successful) one. "This is a lesson the youth must imbibe," Modi said.
