The memoir of John Lennon's first wife, Cynthia, tells how the Beatles -- ready for new ways of thinking -- visited the ashram of Maharishi Mahesh Yogi. Ringo ran out of the canned food he had brought along and went home after two weeks. Paul left a few days later but became a lifelong vegetarian. John and George stayed two months. John wrote a nasty song about the Maharishi, and George integrated the teachings into his daily life.
