雲門匡真禪師廣錄 2.47

2.47

One day the Master held up his staff and cited the teaching: "Ordinary people take it as real and call it 'existent'; the two vehicles analyze it and call it 'non-existent'; the pratyekabuddhas call it 'illusory existence'; the bodhisattvas recognize that its very substance is empty." He then said, "When patch-robed monks see a staff, they just call it a staff; when walking they just walk, when sitting they just sit—in no way may they stir."
