Query: A Night of Serious Thinking

When I stumbled across this book twelve years ago at a used bookstore in Berkeley, I had no idea what I was in for...I was simply drawn to the title, and I had certainly never heard of Daumal at the tender age of 21. My favorite quote from the novelette: "There are only three exits here: madness and death." It is impossible for me to fathom that you, too, will not cherish this book beyond any other. Never before had I identified so readily with an author's depiction of the absurdity of modern humanity. Truly a treat. Out of print! Get it while you can!
