Imagine the spirit as a mansion. You'll guess we don't use many rooms. Apart from a few moments in childhood we don't dance around it in sunlight. But there's a traffic of things in and out, and what happens is that unwanted bulks can gather inside. Gather and gather, menacing us. Unable to shift them, we hide in ever-smaller spaces. And in our last hole, life offers a choice: to play out our demise in parallel theatres - psychosis, zealotry, religion, cancer, addiction - or to bow quietly out. But beware: life doesn't ask these high questions when we're confident and fresh - it waits for hopelessness.
