In February 1968, the Beatles travelled to Rishikesh, in northern India, to attend an advanced Transcendental Meditation (TM) training session at the ashram of Maharishi Mahesh Yogi. Amid widespread media attention, their visit was one of the band's most productive periods. Led by George Harrison's commitment, the Beatles' interest in the Maharishi changed Western attitudes about Indian spirituality and encouraged the study of Transcendental Meditation.
The Beatles first met the Maharishi in London in August 1967 and then attended a seminar in Bangor, Wales. They had planned to attend the entire ten-day session, but their stay was cut short by the death of their manager, Brian Epstein. Wanting to learn more, they kept in contact with the Maharishi and made arrangements to spend time with him at his teaching centre located near Rishikesh, in "the Valley of the Saints" at the foothills of the Himalayas.
Along with their wives, girlfriends, assistants and numerous reporters, the Beatles arrived in India in February 1968 and joined the group of 60 people who were training to be TM teachers, including musicians Donovan, Mike Love of the Beach Boys, and flautist Paul Horn. While there, John Lennon, Paul McCartney and Harrison wrote many songs and Ringo Starr finished writing his first. Eighteen of those songs were recorded for The Beatles ("the White Album"), two songs appeared on the Abbey Road album, and others were used for various solo projects.
Starr and his wife left on 1 March, after a ten-day stay; McCartney left after one month due to other commitments; while Lennon and Harrison stayed about six weeks, then left abruptly following financial disagreements and rumours of inappropriate behaviour by the Maharishi. Harrison later apologised for the way he and Lennon had treated the Maharishi, and in 1992 gave a benefit concert for the Maharishi-associated Natural Law Party. In 2009, McCartney and Starr performed at a benefit concert for the David Lynch Foundation, which raises funds for the teaching of Transcendental Meditation to at-risk students.
