India is a culture in which religious life and spirituality is very much on the surface of things. That doesn't mean it doesn't have depth, but it is very visible. There are lots of temples, lots of Islamic centers, lots of gurdwaras, and lots of teachers.

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.

Be prepared for changes.

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

The journey to sacred places is the most common way that people travel in India. They are always going on pilgrimages to sacred places. They are always undertaking spiritual journeys to visit the great shrines in the Himalayan tier of pilgrimage places; these places are called tirthas, a word that means "crossing place," a place where you can cross the river to the far shore but also cross over into another dimension of life. Cross over to heaven, in one sense it's used.

People get tired of talking about American exceptionalism, but I think this is an extraordinary thing about the United States, that we are a nation of immigrants, first of all, that is built upon a pluralistic society of native people that were here to begin with. The issue of diversity is really with us from the beginning.

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.
