Hekiganroku: Nansen Draws a Circle (a Genjo Roshi teisho)

Genjo Marinello Roshi gave Teisho on the Hekiganroku case 69, "Nansen Draws A Circle," at No-Rank Zen Temple's Sept. 1st Zazenkai. Sadly the recording of this talk was lost. He reprised it during the Sept. 8, 2024 Zazenkai at Chobo-Ji. It explores the Zen enso and its meaning.  How do we sit in the middle of the circle of form and non-form?
