John Sherman was born in Camden, New Jersey. From adolescence he lived a life of crime, first to make a living and later for political reasons. His worst crimes include bank robbery and acts of sabotage. He was sent to prison several times but managed to escape. This caused him to be put on FBI's Ten Most Wanted list. He was caught again, and while serving his thirty-year sentence decided to live a life in accordance with the law.
About halfway through his sentence Gangaji came to visit Sherman's prison. He had by then been a practicing Buddhist, but it was her teaching that led to the spiritual breakthrough that was to mark him since. She introduced him to Ramana Maharshi whose constant advocacy of self-enquiry inspired Sherman to devote most of his time to that practice. After leaving prison he worked with the Gangaji Foundation.
