Since it was first published in 1980, Dan Millman's "Way of the Peaceful Warrior" has become a New Age classic. It tells the story of a chance encounter between a college-age gymnast and a man he calls Socrates who mentors him through a transformational spiritual journey. A movie of the book, called "Peaceful Warrior," opens June 2, starring Nick Nolte as Socrates. Watch clips from the film below:
