In this talk, given during the second one-day sitting of the winter 2024 practice period, Abiding Abbot Dōshin Mako Voelkel discusses the power and peace of not-knowing. In the Zen tradition, ‘not-knowing’ is not the same as the ignorance or delusion of everyday life. When we deeply and fully ‘don’t know’ we are more able to be at peace with things as they really are, and can see and respond to circumstances of our world as they arise and pass in each moment. This talk was recorded during the February one-day sitting, held at Unity Church, a neighbor of San Francisco Zen Center’s City Center congregation.
