Step-by-step explanation:
The Maharishi Mahesh Yogi founded the meditative philosophy known as Transcendental Meditation (TM). Originating from the ancient Vedic tradition of India, TM was popularized in the mid-20th century and gained international fame in the 1960s when The Beatles visited the Maharishi in India. Transcendental Meditation is a form of silent, mantra meditation that is practiced for 20 minutes twice a day. It's designed to allow the individual's active mind to experience a state of profound rest and relaxation, thereby achieving a unique state of consciousness. Since its introduction to the West, TM has become one of the most widely practiced and researched forms of meditation. The Maharishi's teachings have influenced people worldwide and continue to contribute to the global understanding and adoption of meditation for health and self-development.
