The Transcendental Meditation movement (also referred to as Transcendental Meditation or TM) refers to the programs and organizations connected with the Transcendental Meditation technique founded by Maharishi Mahesh Yogi in India in the 1950s. The organization was estimated to have 900,000 participants in 1977, a million by the 1980s, and 5 million in more recent years.
Programs include the Transcendental Meditation technique, an advanced meditation practice called the TM-Sidhi program ("Yogic Flying"), an alternative health care program called Maharishi Ayurveda, and a system of building and architecture called Maharishi Sthapatya Ved. The TM movement's past and present media endeavors include a publishing company (MUM Press), a television station (KSCI), a radio station (KHOE), and a satellite television channel (Maharishi Channel). Its products and services have been offered primarily through nonprofit and educational outlets, such as the Global Country of World Peace, and the David Lynch Foundation.
The TM movement also operates a worldwide network of Transcendental Meditation teaching centers, schools, universities, health centers, and herbal supplement, solar panel, and home financing companies, plus several TM-centered communities. The global organization is reported to have an estimated net worth of USD 3.5 billion. The TM movement has been characterized in a variety of ways and has been called a spiritual movement, a new religious movement, a millenarian movement, a world affirming movement, a new social movement, a guru-centered movement, a personal growth movement, a religion, and a cult, with one observer disputing the cult label. Participation in TM programs does not require a belief system and is practiced by people from a diverse group of religious affiliations.
