191. The Zen practitioner is not an isolated individual. He or she belongs to a sangha, a community of fellow practitioners that is committed to the path under the guidance of a master. As sangha members practitioners are expected to contribute to the running of the community and to help build up sangha relations. An important way to do this is through the practice of samu. Samu is a form of work in the service of the sangha. In this practice members interact with one another. By cooperating on various projects they come to respect and value one another. Membership of the sangha is a great lesson in how to step from the top of the hundred foot pole.
