Maharishi Mahesh Yogi (January 12, 1918 – February 5, 2008), introduced the Transcendental Meditation technique (also known as TM) and related programs and initiatives, including schools and universities with campuses in countries like India, the United States, Mexico, the United Kingdom and China.
In approximately 1939, the Maharishi became a assistant of Swami Brahmananda Saraswati, who, from 1941 to 1953, was the Shankaracharya (spiritual leader) of Jyotir Math, located in the Indian Himalayas. The Maharishi credits the Shankaracharya (Guru Deva) with inspiring his teachings.
Maharishi Mahesh Yogi's first global tour began in 1958, from which time his techniques and programs have been taught worldwide. He became known in the Western world in part due to his interactions with The Beatles and other celebrities.
