More than any religious figure that I can think of, Dalai Lama goes out of his way to attend interfaith conferences; religious harmony is one of his urgent priorities in life.

To this day, at my relatively advanced age, I still don't have a place I can really call home. I've never bought property. I just move between temporary base camps. I know that the very notion of home, of having a family or community, is a hard one for me to embrace.

I think Dalai Lama efforts have been heroic.

As soon as I'm on the road, I see, often palpably, that I know nothing at all, which is always a great liberation.

Often when we think of exile we think of destruction or loss. But the Dalai Lama always says exile is reality, it's something we can make use of, and he has used it to get rid of everything that he thought was stifling and old, and to create a new, improved and much healthier Tibet.

We can better see what we don't have. The other man's grass is always greener and now we can actually go and visit his grass much more and feel the absence of green in our own lives.

So travel for me is an act of discovery and of responsibility as well a grand adventure and a constant liberation.
