Those are big challenges in our age, not just how we live as co-citizens in societies with people of different faiths and different cultures - I mean, that's a big challenge itself - but how we think about all that as Christians, or as Jews, or as Muslims, or as Hindus. How do we think about the religious other? There's a theological dimension as well as a civic dimension to our pluralism.

I do think that the U.S. has an opportunity as a democracy to really exemplify what a religiously diverse society can be when it embraces the pluralism.

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.

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.

Pluralism isn't just diversity; it's something we create out of this diversity.

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.
