Transcendental Meditation known as TM has established all this 40 to 50 years ago in North America, courtesy of Maharishi Mahesh Yogi, but society wasn't ready for it. Packaged in new-speak, it sounds like something new and sellable. Psychologists like Persinger from Laurentian University pooh-poohed it, and others accused it of religious trappings, a false defensive reaction to something new (at least in North America).  I have been using this technique for more than 40 years. Granted there are more than one way to meditate, but I have found this mantra system from the Hindu tradition most beneficial for me. The technique is not religious, but works well if used regularly. Maharishi International University in Fairfield, Iowa has established a wealth of research documenting the beneficial effects of daily meditation as well doing research in  many other avenues of science and the humanities. 

Meditation or mindfulness does work if people use it on a regular basis.
