I'd spent thirty years visiting the Dalai Lama, and twenty years as a journalist going to difficult places, war zones and revolutions from North Korea to Haiti and Beirut to Sri Lanka, and the question came up: What does this man have to offer to this world which seems so torn up and so attached to conflict?

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.

For if every true love affair can feel like a journey to a foreign country, where you can’t quite speak the language, and you don’t know where you’re going, and you’re pulled ever deeper into the inviting darkness, every trip to a foreign country can be a love affair, where you’re left puzzling over who you are and whom you’ve fallen in love with.

In terms of technology and science, tomorrow does know more than yesterday; but when it comes to emotions, living with uncertainty, terror, I'm not sure we know any more than Shakespeare did, or the Buddha.
