Transcendental meditation is like a car, a vehicle that allows you to go within. It's a mental technique. You're given a mantra - the mantra that Maharishi gives is very specific, and you start to dive into subtler levels of mind, subtler levels of intellect. You transcend the whole show, into pure bliss consciousness. From your first meditation, you say, "Whoa!" It's a unique experience, but a familiar experience.
