Reflections on Zen and Sangha

My intention is to capture here some occasional reflections about Zen and especially the pillar of Buddhist tradition, Sangha. I am interested in how sanghas can be developed in ways that are healthy, how they thrive, how they manage to continue, under all kinds of circumstances, challenges, and change. I am going to turn comments on, as long as comments continue to be courteous and respectful. I welcome conversations about these topics.
