Some of the Beach Boys and the Beatles practiced Transcendental Meditation thanks to a run-in with Maharishi Mahesh. Here’s what Jardine said about how he got started with TM.
Some Beatles were deeply involved with meditation practices, especially guitarist George Harrison. Thanks to one YouTube video, The Beach Boys’ Jardine elaborated on his experience with Maharishi Mahesh Yogi’s Transcendental Meditation — actually, two Beatles inspired him to start the practice.
In the 1960s, The Beach Boys were invited to perform for a UNICEF event in Paris, France. On the way over, they played a concert in London, England. At one point, Jardine heard a knock on his door, and “there were two Beatles standing there.” It was John Lennon and Harrison, who asked if they could come in, and Jardine obliged.
