The ancient wisdom the Dalai Lama hopes will enrich the world

It isn't often you meet the leader of a world religion - rarer still that he tweaks your cheek. But that's what happened when I met the 14th Dalai Lama last month.

You know when he has entered a room. First there is a hush and, almost immediately after that, a ripple of infectious laughter. Next, there he is, his face creased into a mischievous smile, his eyes twinkling behind his tinted spectacles.

I met his holiness in Bodh Gaya, the northern Indian town where Buddha himself is said to have attained enlightenment. It is an auspicious place to meet the leader of Tibetan Buddhism, and it was also an auspicious day.
