 After 1968 the Maharishi fell out of the public spotlight for a period and TM was described as a passing fad . Mike Love arranged for the Beach Boys to tour with the Maharishi in the US during the summer of 1968 . However , the tour was cancelled after several appearances and was called " one of the more bizarre entertainments of the era " . Interest grew again in the mid @-@ 1970s when scientific studies began showing concrete results . The Maharishi moved to Europe in the early years of that decade and appeared twice on American television 's The Merv Griffin Show in the mid 1970s , leading to a surge of popularity called the " Merv wave " . That was followed by the introduction of " Yogic Flying " , a technique which offered the promise of levitation . In a 1975 interview , Harrison said of the Beatles ' association with Transcendental Meditation : " In retrospect , that was probably one of the greatest experiences I 've ever had … Maharishi was always put down for propagating what was basically a spiritual thing but there 's so much being propagated that 's damaging to life that I ’ m glad there are good people around like him . " In 1978 Lennon wrote that he considered his meditation a " source of creative inspiration " .
