Maharishi Mahesh Yogi, a guru to the Beatles who introduced the West to transcendental meditation, died Tuesday at his home in the Dutch town of Vlodrop, a spokesman said. He was thought to be 91 years old.

"He died peacefully at about 7 p.m.," said Bob Roth, a spokesman for the Transcendental Meditation movement that Maharishi founded. He said his death appeared to be due to "natural causes, his age."

Once dismissed as hippie mysticism, the Hindu practice of mind control known as 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 attended one of his lectures in 1967.

Maharishi retreated last month into silence at his home on the grounds of a former Franciscan monastery, saying he wanted to dedicate his remaining days to studying the ancient Indian texts that underpin his movement.

"He had been saying he had done what he set out to do," Roth said late Tuesday.

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. His roster of famous meditators ran from Mike Love of the Beach Boys to Clint Eastwood and Deepak Chopra, a new age preacher.

After 50 years of teaching, Maharishi turned to larger themes, with grand designs to harness the power of group meditation to create world peace and to mobilize his devotees to banish poverty from the earth.
