In the very begining of Shobogenzo, Dogen quotes a famous poem of Nyojo, his teacher:
My late master, the eternal buddha, says:
Whole body like a mouth, hanging in space;
Not asking if the wind is east, west, south, or north,
For all others equally, it speaks praj˝?.
Chin ten ton ryan chin ten ton.
Free, careless, empty, the bell and the sound cannot be broken in two. Is the bell just a bell? Isn't the bell bigger, much larger? How large, how big is it? And where are you in the picture?
