(you perhaps):
"...all things change in time; some are made of change itself, and the poem is of these. It is not an object; the poem is a process... it is available, heard once, or... always at hand... that climate of excitement... announcing with the poem that we are about to change, that work is being done on the self."
— Muriel Rukeyser, The Life of Poetry [1949] (Paris Press, 1996) p174-175.
