Actually, the review misquoted it as "the" world, but I googled it and found it was from a poem called "Spring". I don't recall ever seeing this poem. It's not, to my mind, very earthshaking, though it's a good enough poem. The thing is, these are exactly two lines that appear in a poem of mine: "Copernican Revolution." Though that poem has gone through many overhauls including the recent addition of a stanza, the original poem, which very much centers around those lines, was from the late eighties. The Oliver poem -- at least the book it was published in -- is from 1992. My poem is unpublished -- though it's in my well-circulated manuscript. I sure don't think Mary Oliver copied those lines from me -- but neither do I remember ever reading that poem or that book or even much Mary Oliver.
So has this ever happened to you? What would you do? Should I remove the poem from my manuscript? Here's the last stanza of "Copernican Revolution":
There’s only one question:
how to love this world, how to find
the will to serve it—
each morning, the new baby skin of light.
