I’d like to expand on a comment that “indrax” made, “* It would give UU's (and others) a place to spend months or years in a calmer lifestyle with time to explore their unique faith.”
A problem for me is that UU is primarily a community of like minded people, many of whom have found their way there from elsewhere. And that is okay as far as it goes.
But UU lacks a theology and an a “yoga” or practice that can enable people to transcend where they are, to become more whole, more integrated, more loving, etc.
A yoga or practice set could be developed. It might look like Buddhist “insight meditation.” It might contain physical practices such as T’ai Chi or yoga. It might stress community service and interpersonal relations.
