The idea of going on a spiritual journey is really part of the DNA of India itself.

My whole worldview has changed because of the work that I do. Specifically, the way in which I appropriate my own faith as a Christian, and the way in which I think about the faith and life of others who are very different than myself. That mutuality of regard is how we deal with difference and diversity in the world.

When immigrants come, the freedom to practice their faith is a guarantee. They may have trouble with their neighbors, but freedom of religion is part of the blueprint for America, and that is the recipe for the religious diversity that we have today.

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.

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.

Be prepared for changes.

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.
