 The Immortals of Meluha was a commercial success. Just after a week of its publication in February 2010, the book hit the best seller list of several magazines and newspapers, including The Statesman, The Economic Times, The Times of India, Rolling Stone India, among others. The book had to be re-printed for another 5,000 copies thrice within the next week, and by the end of July, it had sold around 45,000 copies across India. Both Tripathi and Tiwari decided that a transfer of the rights of the book to a larger publisher was needed, so as to take the book to higher grounds. Many publishers bid for it, but they went with Westland Publishers, who had been the distributing partner for the book. The Westland edition of the book was published on 10 September 2010, in Delhi amidst a media frenzy. It was launched by former UN diplomat Shashi Tharoor, who praised it. The edited version of The Immortals of Meluha was accompanied by the release of an audiobook for the novel. As of January 2013, The Immortals of Meluha, and its sequel, The Secret of the Nagas, have crossed a print run of a million copies. These books have continued to top the bestseller lists of Nielsen BookScan, with the gross retail sales being impressive at ₹ 22 crore (US $ 3.3 million) within two years of publishing. As of June 2015 over 2.5 million copies of the Shiva Trilogy have been sold and have also made over ₹ 60 crore (US $ 8.9 million) in revenue.
