Having done TM as well as Vipassana (discussed in the original article) and other meditations, I do not recommend TM. You will do just fine (or better) with other things. TM happens to have some famous exponents (e.g. David Lynch) but I find it a somewhat cult-like money extraction machine, and the actual meditation they teach to be less worthwhile than the other flavors of meditation in which I have experience.
It feels like a huge PR stunt to sell his certified "Transcendental Meditation®" trainings. Does anyone here have an insight into that?
