In this Dharma talk, given by Rinzan Pechovnik Osho during the first day of Odayaka sesshin (01/25/2019), Rinzan Osho examines Case #1 of the Mumonkan, "Joshu's Mu." Foundational Buddhist teaching states that all beings have Buddha Nature. Why then, when a monk asked if a dog has Buddha Nature, did Joshu say, "Mu?" ("Wu" in Chinese.) Mu is often translated as "No." Is this what Joshu met, or was he inviting the monk into an intimacy beyond yes and no, has and has not?
