I have come to deep appreciate the power of dialogue. My most profound experiences have been in what Dr. Parker Palmer calls Circles of Trust, which I would describe as a method of exploring one’s spirituality outside the framework of religious traditions.
The ability to speak one’s truth and to be listened to in an open and loving way is life changing; and, of course, to do that for everyone else in the circle.
I also have seen the power of a technique called the World Café. It helps the knowledge and diversity of everyone in the group to emerge into a greater wisdom than any one individual.
