Clear Water Zendo is a Zen Buddhist practice community in Vallejo, California. Formally opened in January 2000, it offers a place for sangha members to practice clarity together through sitting, quieting the mind, and paying attention. The community emphasizes shared care of the zendo and mutual support. Its priest, Mary Mocine, trained at San Francisco Zen Center and Berkeley Zen Center, including four years at Tassajara Zen Monastery, and senior lay leaders help guide the zendo.
