In the early 1920s, Jaydayal Goyandka and Hanuman Prasad Poddar, two Marwari businessmen-turned-spiritualists, set up the Gita Press and Kalyan magazine. As of early 2014, Gita Press had sold close to 72 million copies of the Gita, 70 million copies of Tulsidas's works and 19 million copies of scriptures like the Puranas and Upanishads. And while most other journals of the period, whether religious, literary or political, survive only in press archives, Kalyan now has a circulation of over 200,000, and its English counterpart, Kalyana-Kalpataru, of over 100,000. Gita Press created an empire that spoke in a militant Hindu nationalist voice. Featuring an extraordinary cast of characters - buccaneering entrepreneurs and hustling editors, nationalist ideologues and religious fanatics - this is essential (and exciting) reading for our times.
