Transcendental Meditation (TM) comes from the ancient Vedic Indian tradition, introduced by Maharishi Mahesh Yogi in 1958.
So how does the transcendental meditation technique work?
It is a simple, easily learned mental meditation technique, practiced for about 20 minutes twice a day, while sitting with your eyes closed. It is quite fun actually, but you do need a TM instructor to teach you the basics.
During this meditation, the mind settles down to a silent, yet awake state of awareness, while the body will be fully rested and relaxed.
I will let Deepak Chopra explain what transcendental meditation technique is.
