Guru to Beatles Dies at 91

The guru to the Beatles, Maharishi Mahesh Yogi , has died at his home in the Netherlands. He was 91.

Once dismissed as hippie mysticism, the Hindu practice of mind control that Maharishi taught, called transcendental meditation, gradually gained medical respectability.

He began teaching TM in 1955 and brought the technique to the United States in 1959. But the movement really took off after the Beatles visited his ashram in India in 1968, although he had a famous falling out with the rock stars when he discovered them using drugs at his Himalayan retreat.

With the help of celebrity endorsements, Maharishi — a Hindi-language title for Great Seer — parlayed his interpretations of ancient scripture into a multi-million-dollar global empire.
