The koan of the Autumn Moon retreat is from one of the great teachers Yun Men. The student asks the teacher, “What is a teaching that will last a whole lifetime?” and the teacher responds, “Say something in response.” October 14, 2012.
On day two of Autumn Moon retreat, John continues with the great Koan from Yun Men.
