萬松老人評唱天童覺和尚頌古從容庵錄 3.103

3.103

Case:
Dongshan made an offering to Yunyan's portrait (who says it is false?). He then raised the previous dialogue about painting the portrait (each time it is brought out, each time it is fresh).
A monk asked, "When Yunyan said, 'Just this is it,' what was his intended meaning?" (One is glad he did not mistake it.)
Dongshan said, "At that time I nearly misunderstood my late teacher's meaning." (Measuring others by oneself.)
The monk said, "I wonder, did Yunyan still know it is there or not?" (Snapping grass to measure heaven.)
Dongshan said, "If he did not know it is there, how could he understand how to speak like that? (The sun rises over the linked mountains.) If he knew it is there, how could he be willing to speak like that?" (The full moon faces the doorway.)
