Invisible Architecture

Barbara Guest's essay "Invisible Architecture" (from Forces of Imagination) is fantastic & selecting excerpts doesn't do the work justice; but here is the butchery nonetheless:

"An architecture in the period before the poem finds an exact form and vocabulary--

before the visible appearance of the poem on the page and the invisible approach to its composition. Reaching out to develop the poem there are interruptions, some apparently for no reason--something else is happening, the poet has no control--the poem begins to quiver, to hesitate, to become insubstantial, the desire of poetry to elevate itself, to become stronger...The poem is fragile."
