I was told a story once about the Zen master, Thich Nhat Hanh, being asked what he had learned from all his years of living in community. He is said to have replied “how to close doors very quietly.”
It’s a witty commentary — and perhaps a caution — on the importance members of a community must give to being mindful of the ways their most ordinary actions may affect others in the community.
I can’t find the source of that Thich Nhat Hanh quote, so it may not be authentic. But in looking for it I stumbled across this lovely reflection on closing doors and mindfulness from a blog on Zen meditation. It has some thoughts on aging and transitions that seem helpful in thinking about co-housing.
