In February 1968, the Beatles traveled 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. (from Wikipedia)
George Harrison had lessons with Ravi Shankar on the shores of the Ganga River in 1968. This was 7 years before I met the legendary sitarist, maestro Ravi Shankar in London.
The connection between the beatles and Japan is obvious to many as John Lennon was married to Yoko Ono.
