A new book on champion batsman Sachin Tendulkar, who celebrates his 36th birthday on Friday in South Africa where he is leading Mumbai Indians in the IPL 2009, was released in Mumbai to mark the occasion. The book, titled If Cricket Is a Religion, Sachin is God, authored by two graduates of IIM (Ahmedabad), Vijay Santhanam and Shyam Balasubramaniam, was unveiled by billiards ace Geet Sethi and former India Test skipper Nari Contractor on Friday. Sethi said, "No need to ask, cricket is a religion in our country and Tendulkar is the epitome of it. There's a huge visibility to Sachin, but I look beyond visibility. I look at his character and hunger (for the game)".
