Thanks for offering this. Sounds like a beautiful model! I’m wondering if you have come across Parker Palmer’s book “A Hidden Wholeness?” He lays out a really beautiful framework for understanding what these kind of spaces are and WHY they are so crucial to sustaining work towards justice and integrity.
I’m a part of a group called “Freedom Beyond” that is working on a circle model that has a lot of similarities to yours, although there are no discussion topics. It could be powerful to share our experiences with our respective models!
