No Right or Wrong in the Tao

Genjo Osho gave this teisho on the last day of Feb. Odayaka Sesshin, 2017. It examines Case 19 of the Mumonkan. What words of Zen Master Nansen broke through Joshu's delusive mind? Nansen said, "How can there be right and wrong in the Tao?" What?  No right or wrong?  How can that be?  Please have a listen.
