Book of Equanimity Case 21 — Ungan Sweeps the Ground

Ungan Sweeps the Ground — The Second Moon and the Problem of EffortBook of Equanimity (Shoyoroku), Case 21With Sensei Sōen Michael BrunnerRecorded at One River Zen (Ottawa, Illinois)The CaseAttention! As Ungan was sweeping the ground, Dogo said, “You’re hard at it!”Ungan replied, “You should know there’s one who isn’t hard at it!”Dogo said, “So, is there a second moon?”Ungan held up the broom saying, “Which moon is this?”Dogo desisted.Regarding this, Gensha remarked, “Indeed, this is the second moon.”Ummon also said, “The butler watches the maid politely.”In This EpisodeIn this teishō, Sensei Sōen Michael Brunner explores one of the most subtle dynamics in Zen practice: the split between activity and commentary.How ordinary activity becomes self-conscious effortThe moment identity forms around strivingWhat Zen calls the “second moon”Why spiritual self-improvement can reinforce dualityThe difference between immersion and evaluationHow intention functions without becoming self-centeredWhy “just keep sweeping” is not passivityThis talk examines how commentary quietly replaces functioning. When Dogo says, “You’re hard at it,” heaven and hell separate—not because sweeping changes, but because narration enters the field.Ungan’s response points beyond both effort and non-effort, yet the trap remains: if there is “one who isn’t hard at it,” has a second self appeared?Gensha’s and Ummon’s remarks sharpen the point. Even subtle spiritual refinement can become a second moon—an observer watching itself practice.Key ThemesActivity vs. identityCommentary as subtle dualityThe “board on your shoulder” metaphorBodhisattva intention vs. spiritual self-makingDogo’s desisting as embodied responseMara and the 108 distractionsReturning to functioningPractice ReflectionWhere does commentary replace action in your own life?When you are working, are you working—or evaluating yourself working?When you are practicing, are you practicing—or narrating the one who practices?The koan does not eliminate effort. It exposes the tightening around effort.Just keep sweeping.About the TeacherSensei Sōen Michael Brunner is the founding teacher of One River Zen in Ottawa, Illinois.
