Transcendental Meditation (TM) refers to a specific form of silent mantra meditation called the Transcendental Meditation technique, and less commonly to the organizations that constitute the Transcendental Meditation movement.Maharishi Mahesh Yogi (1918–2008) introduced the TM technique and TM movement in India, in the mid-1950s.
The Maharishi taught thousands of people during a series of world tours from 1958 to 1965, expressing his teachings in spiritual and religious terms. TM became more popular in the 1960s and 1970s, as the Maharishi shifted to a more technical presentation, and his meditation technique was practiced by celebrities. At this time, he began training TM teachers and created specialized organizations to present TM to specific segments of the population such as business people and students. By the early 2000s, TM had been taught to millions of people, and the worldwide TM organization had grown to include educational programs, health products, and related services.
The TM technique involves the use of a sound or mantra, and is practiced for 15–20 minutes twice per day. It is taught by certified teachers through a standard course of instruction, which costs a fee that varies by country. According to the Transcendental Meditation movement, it is a non-religious method for relaxation, stress reduction, and self-development. Varying views on whether the technique is religious or non-religious have been expressed including by sociologists, scholars, and a New Jersey court. The United States Court of Appeals upheld the federal ruling that TM was a religion and therefore could not be taught in public schools.
TM is one of the most widely practiced and researched meditation techniques. It is impossible to say whether it has any effect on health, as the research to date is of poor quality.
Transcendental Meditation dates its origin back to the Vedic traditions of India. The Transcendental Meditation program and the Transcendental Meditation movement originated with Maharishi Mahesh Yogi, founder of the organization, and continue beyond his death in 2008. In 1955, "the Maharishi began publicly teaching a traditional meditation technique" learned from his master Brahmananda Saraswati that he called Transcendental Deep Meditation and later renamed Transcendental Meditation. The Maharishi initiated thousands of people, then developed a TM teacher training program as a way to accelerate the rate of bringing the technique to more people. He also inaugurated a series of world tours which promoted Transcendental Meditation. These factors, coupled with endorsements by celebrities who practiced TM and claims that scientific research had validated the technique, helped to popularize TM in the 1960s and 1970s. By the late 2000s, TM had been taught to millions of individuals and the Maharishi was overseeing a large multinational movement. Despite organizational changes and the addition of advanced meditative techniques in the 1970s, the Transcendental Meditation technique has remained relatively unchanged.
