Readings: a Whole Fragment

These are the last five lines of a poem entitled "A Room" by Jane Hirshfield. There are seventeen lines preceding these five; but they stand quite well alone:

pointing to hinge and plaster and wood --

xxxYou are matter, as they are.
xxxSee how perfectly it can be done.
xxxHold, one day more, what is asked.
