This year 83,000 people flocked to Olympia for the second Festival for Mind and Body. Why? What is the attraction of this annual spiritual supermarket where health food stalls vie with do-it-yourself Yoga, and Tibetan Buddhists are wired to bio-feedback machines? Are these more than the fads and fashions of a gullible post-Christian age? This Everyman film looks at the Festival through the eyes of Sir George Trevelyan , once a teacher at Gordonstoun, now the leading prophet of the New Age: ' It's not a religious revolution with any dogma you've got to believe in - it's a spiritual awakening.'
