Prudence Farrow wanted to "Teach God quicker than anyone else," according to John Lennon. She would lock herself in her room trying to meditate for hours and hours. From A Hard Day's Write
, by Steve Turner: "At the end of the demo version of Dear Prudence John continues playing guitar and says: 'No one was to know that sooner or later she was to go completely berserk, under the care of Maharishi Mahesh Yogi. All the people around were very worried about the girl because she was going insane. So, we sang to her.'"
Prudence Farrow explained years later that she was just trying to take Transcendental Meditation seriously. She said in Mojo
magazine, September 2008: "They were trying to be cheerful, but I wished they'd go away. I don't think they realized what the training was all about."
