Hrithik first ordered the book, which was being endorsed by Hollywood celebrities like Anthony Hopkins and Ashton Kutcher, for himself. When the book arrived, he spent time alone and finished the book in a day.
Seven days later, he turned into a non-smoker, according to a source close to the 37-year-old.
The actor has now bought 40 copies of the book to distribute amongst family, friends and needy strangers too. From the film industry, Sanjay Dutt and Bobby Deol have already been given a copy each, said the source.
