And if travel is like love, it is, in the end, mostly because it's a heightened state of awareness, in which we are mindful, receptive, undimmed by familiarity and ready to be transformed. That is why the best trips, like the best love affairs, never really end.

For more and more of us, home has really less to do with a piece of soil than, you could say, with a piece of soul. If somebody suddenly asks me, "Where's your home?" I think about my sweetheart or my closest friends or the songs that travel with me wherever I happen to be.

[The Dalai Lama] told me some years ago, "I've made every concession to China, and I've been as open and tolerant as I could, and still things get worse in Tibet." If you look at it from one point of view, as he himself says, his monastic position of forbearance and nonviolence hasn't reaped any benefits. And yet, he's thinking in terms of the long term, of centuries.

Travel spins us round in two ways at once: It shows us the sights and values and issues that we might ordinarily ignore; but it also, and more deeply, shows us all the parts of ourselves that might otherwise grow rusty.

In an age of distraction, nothing can feel more luxurious than paying attention.

Yes, we know more than ever before, and it's a wonder that we get to inhabit a world full of driverless cars and 3D printers. But that doesn't mean that we know any more about the essential things in life - love, faith, death - and it would be dangerous to assume we did. The only thing that gets us through sometimes is a proper, humbled sense that we don't have a clue, we can't be sure what's going to happen next and life will always be much larger than our ideas of it.

Our own country seemed more polarized than it's ever been and since the two terrorist attacks of 9/11, religion was in greater disrepute than at any other time in my lifetime.
