A monk asked Xuedou, “What is your manner of teaching?”
Xuedou replied, “When guests come, one should see them.” (quoted in Zen Essence)
If you have been reading this blog from the very beginning, and have a good memory, or if you have read the Tenzokyokun a fair number of times, the name Xuedou will ring a bell. Dogen quotes his wonderful poem in that piece, and I recently dug out the three translations I have to look at with my students. I think what he is saying in this exchange is very much in line with the poem, though perhaps easier to grasp.
