Here is a discussion between Ken Wilber and Fr. Thomas Keating. These two men are two of the greatest thinkers of our time. I believe Fr. Keating has done more to transform the spiritual landscape in America that anyone since Thomas Merton. He is responsible in large part for the re-introduction of silent contemplation within many Christian communities. Fr. Thomas Keating is a deeply realized individual, and I say this not because he says brilliant things or sounds incredibly intelligent, but because he is relaxed and himself. That is what I find admirable, and so does Ken Wilber (watch his face throughout the interview; he has this goofy smirk!)
It is a bit longer than most of the videos I select, but I find it incredibly interesting, and a very enjoyable 15 minutes.
