Zen master Seung Sahn and taoist Miao

[Mornings Son]

Zen Master Seung Sahn held up his staff in front of old Shifu Miao Zhang, and said "Then, Miao Zhang, what are this staff, this sound and your mind?  Are they the same or different?  If you say "same," I will hit you thirty times.  If you say "different," I will also hit you thirty times. Why?"
Miao Zhang lifted his cane slowly and pointed it at Seung Sahn's face, and then he said "Don't know! Same or different, nobody can hit the sound of our minds."
