Born in Madras, India, in 1946, he survived a suicide attempt as a 17 year-old university student. 'It was a very considered decision at that time - not the result of a trauma or depression. It was just the fact that life lacked meaning,' he said. From his hospital bed in New Delhi, he remembers vowing: 'I will leave no stone unturned in my pursuit of truth.' It was then he became a Christian.
