"Dear Prudence" is a song written by John Lennon, and credited to Lennon/McCartney. It was recorded by The Beatles as the second track on their 1968 double-disc album entitled The Beatles (also known as The White Album).
The subject of the song is actress Mia Farrow's sister, Prudence Farrow who was present when The Beatles went to India to study with Maharishi Mahesh Yogi.
Farrow became so serious about her meditation that she “turned into a near recluse” and “rarely came out” of the cottage she was living in. Someone asked John Lennon to “contact her and make sure she came out more often to socialize”. As a result, Lennon wrote the song Dear Prudence. In the song Lennon asks Farrow to “open up your eyes” and “see the sunny skies” reminding her that she is “part of everything”. The song was said to be “a simple plea to a friend to ‘snap out of it’". Lennon said later that “She’d been locked in for three weeks and was trying to reach God quicker than anyone else”. According to Farrow: "I would always rush straight back to my room after lectures and meals so I could meditate. John, George and Paul would all want to sit around jamming and having a good time and I'd be flying into my room. They were all serious about what they were doing, but they just weren't as fanatical as me."
