Bob Roth, Meditation Teacher to the Stars

Oprah Winfrey, Tom Hanks and David Letterman are just some of the dozens of celebrities who sought out Bob Roth to learn Transcendental Meditation (TM), a mantra-focused meditation practice. Roth, who has been a meditation teacher for over 40 years and has a new book out called, "Strength in Stillness," talks about how he found TM and addresses the criticism and suspicions some former members have raised around TM.
