The issue of "who we are" has been an ongoing one. It's part of the ongoing identity crisis of America.

That is the strength of having a trusting and ongoing relationship that draws on our history and moves right on into our present, and I have that kind of marriage.

If you went to the headwaters of most rivers of the United States, you'd have a wonderful naturalistic hike or trek, but you wouldn't find a shrine there. At the headwaters of the rivers of India, they are pilgrimage places.

I grew up going around with family, camping and living in a very beautiful mountain valley, knowing the names of the mountains and the rivers. I think it's no accident that I ended up studying the geography of India and knowing the names of the mountains and the rivers and all of that. I loved it. I think it gives a sense of space and a can-do-ness that was very powerful.

There's still plenty of people who have this deep conviction that America is a Christian country and ought to say so in its Constitution, etc. But that's not the legal basis on which we're framed. So the flourishing of religion, of religious diversity, is really built into who we are.

We are built on a structure of the freedom of religion and the non-establishment of religion. That really is a pretty sturdy rudder for the U.S.

Places where one can experience some of that separation from the world of the familiar, to defamiliarize ourselves with what we take for granted and enter into the ebb and flow of another culture, it certainly is one of the more valuable things that we do as human beings.
