“I am closest of all to happiness—although I won’t attempt to define just what it is—when I turn away from the window and am aware, with the edge of my consciousness, that a moment ago I was not here, there was simply the world outside the window, and something beautiful and incomprehensible, something which there is absolutely no need to ‘comprehend,’ existed for a few seconds instead of the usual swarm of thoughts, of which one, like a locomotive, pulls all the others after it, absorbs them all and calls itself ‘I’.”
