Transcendental Meditation (TM) is a specific form of meditation that was developed by Maharishi Mahesh Yogi in the 1950s. It is a mental technique that involves the use of a mantra, which is a sound or word that is repeated silently to help focus the mind and reach a state of deep relaxation and mental tranquility.

In TM, the practitioner sits comfortably with their eyes closed and repeats the mantra to themselves for a set period of time, typically 20 minutes twice a day. The aim of the practice is to transcend, or go beyond, the normal state of waking consciousness and access a deeper state of awareness and inner peace.

TM has been described as a simple, effortless and natural technique that can reduce stress, improve mental clarity and physical well-being, and promote a sense of inner fulfillment and happiness. It is also said to be easy to learn and integrate into daily life.

Transcendental Meditation has been the subject of some scientific research, although the results have been mixed and more research is needed to fully understand its effects. Some people find it to be a valuable tool for personal growth and well-being, while others view it as just one of many forms of meditation with limited scientific support.
