Hakubai Zen Center is in Boulder, Colorado, where we practice in the tradition of the Soto School of Japan, in the lineage of Tenzan Keibun Daiosho, and Houn Kobun Roshi.

We practice zazen while sitting, standing up, walking, lying down and getting up, brushing our teeth, eating, bathing, working, and so forth. Morning service and sitting is from 5:30-7:20 a.m. We have three or more sesshins (retreats) during the year. Other programs include baby blessings, funerals, weddings, and ordinations. See the Practice Schedule and Events for up-to-date information.

Please note the Center grounds are part of the training facility and not open to the public except by reservation. If you are interested in visiting Hakubai Zen Center, please contact us for further information. Please see our facility rental page for more information about holding an event at the center.

He is also an advocate of contemplative design and engaged in teaching with his wife through lectures and workshops. Together they have written two books: “Landscape as Spirit: Creating a Contemplative Garden," and "The Sound of Cherry Blossoms: Zen Lessons from the Garden on Design.” Daishin Sensei also recently spoke with Spirituality and Health magazine about contemplative design.

He studied art and Sanskrit at Yale, where he specialized in the Vedas. From 1972-1987, he trained in Tibetan Kagyu Buddhism with Chogyam Trungpa Rinpoche.

He is a lineage bloodline of both Tenzan Keibun Roshi and Houn Kobun Roshi.
