"Very much of my poetry is, I know an enquiry and a terror of fearful expectation, a discovery and facing of fear. I hold a beast, an angel, and a madman in me, and my enquiry is as to their working, and my problem is their subjugation and victory, downthrow & upheaval, and my effort is their self-expression."
January 1, 1970
