As recently as the 1950s, Crane Brinton, the distinguished historian of ideas, could dismiss "modern groups that appeal to Eastern wisdom" as being in effect "sectarian", "marginal", and "outside the main current of Western thought and feeling".[63] Yet some Westerners have converted to Eastern religions or at least have shown an interest in them. An example is Maharishi Mahesh Yogi, whom the Beatles followed, first to Bangor in Wales in 1967, and subsequently to India to study Transcendental Meditation in 1968. The Dalai Lama, whose book The Art of Happiness became a best-seller, can attract huge crowds in New York's Central Park or London's Wembley Stadium.[64]
