Now, I just want to sit still for years on end, really, charting that inner landscape because I think anybody who travels knows that you’re not really doing so in order to move around—you’re traveling in order to be moved. And really what you’re seeing is not just the Grand Canyon or the Great Wall but some moods or intimations or places inside yourself that you never ordinarily see when you’re sleepwalking through your daily life. I thought, there’s this great undiscovered terrain that Henry David Thoreau and Thomas Merton and Emily Dickinson fearlessly investigated, and I want to follow in their footsteps.
