When the Dalai Lama paid a visit to Emory University, he offered an introductory lecture to Tibetan Buddhism. The lecture is not exactly what you'd normally get in the university classroom. The talk is not entirely linear. And he spends some time speaking in English, then speaks in his native tongue (with the help of an interpreter). But, he can talk about Buddhism with the authority that few authors can, and there's a reason audiences come to see him in droves. Things really get going about 23 minutes in.
