Hekiganroku: Isan's "I Would Ask You to Say It."

In this Rohatsu Sesshin Teisho, given at Chobo-ji on Dec. 7th, 2021, Rinzan Osho examines the Hekiganroku Case 70: Isan's "I Would Ask You to Say It." When asked by the master to say "It" without moving his lips or mouth, Isan replied fully. What is it to be intimate? What is it listen, to share, to commune? What is it to hear the mountain and moon speak?
