撫州曹山本寂禪師語錄 1.16

1.16

師行脚時，問烏石觀禪師：「如何是毘盧師、法身主？」烏石曰：「我若向爾道，即別有也。」師舉似洞山，洞山曰：「好箇話頭，秖欠進語。何不問為甚麼不道？」師却去，進前語，烏石曰：「若言我不道，即瘂却我口；若言我道，即謇却我舌。」師歸舉似洞山，洞山深肯之。

When the Master was on pilgrimage, he asked Chan Master Wushi Guan, 'Who is the master of Vairocana and the lord of the dharmakāya?' Wushi said, 'If I were to tell you, there would be someone else.' The Master brought this up to Dongshan. Dongshan said, 'A fine topic for contemplation (huatou), but it just lacked a follow-up word. Why didn't you ask, "Why don't you speak?"' The Master went back and stepped forward with that question. Wushi said, 'If I say that I do not speak, that would mute my mouth; if I say that I do speak, that would stumble my tongue.' The Master returned and presented this to Dongshan, and Dongshan deeply approved of it.
