More than 700,000 have signed up for the Tolle/Oprah 10 week course, and it is also the most popular podcast on iTunes. Very impressive in terms of numbers alone, and even more impressive considering that Tolle is a genuine a mystic as any. His namesake had only a handful of listeners, at most.
I watched the first episode, and thought it was well worth it. I found it especially interesting to see how Tolle and Oprah helped bridge the gap between fundamentalism and a more open approach, and also between traditional religion and spirituality.
