I will say that the power of being a stranger in someone else's religious community has its own lessons, really. It is something like the power of visiting another very happy extended family and being at their table.

My first intellectual challenge was to try to understand this incredible city of Banaras (also called Varanasi) in India and its meaning for Hindus. That was the place I lived for the first year I was in India and I've been back many times. It's a kind of home to me.

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

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.

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.

The idea that the United States government would have to figure out what to do about the headscarf is simply ludicrous. We don't get involved in that.

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.
