Poem is wave.
At poem's base is the depth of our unknowing. At its crest our knowing. In the movement between—poem's urgent momentum.
Because poem's very form acknowledges both what can be said or known and never said or known, poetry may be as close as we come through language to the sacred.
—Betsy Warland, "Nose to Nose" in Only This Blue
I can get behind this formulation, and in fact I've said similar things. What stops me short is the word "sacred." What does sacred mean in this context?
