Bob Thurman is an American Buddhist. At TED2006, he gave a great introduction to the ideas of interconnectedness and compassion. It’s a really good summary of the concepts; he has fun with them rather than dwelling on their nature and substance.
I found this though of personal value, who gives a great synopsis thusly:
It struck me because I’ve always considered how heartbreaking it is to be compassionate if it means taking on another person’s pain. He explains this paradox of how embracing someone else’s pain actually makes us see ourselves differently. And most remarkably, the way to help those who suffer is by having a good time. You have to listen to him to really make sense of this, but in part the key to compassion is that it is more fun (and by this I think he means rewarding) than focusing on only yourself.
