... Stevens does not think of inspiration (or whatever you want to call it) as a condition of composition. He too is waiting for the spark from heaven to fall—poets have no choice about this—but he waits writing; and this—other things being equal, when it's possible, if it's possible—is the best way for a poet to wait.
