Robert Thurman is a professor of Indo-Tibetan Buddhist studies at Columbia University. He was one of the first American Buddhist monks of the Tibetan tradition and he has studied with and become a close friend of the Dali Lama. Being the father of ultra-hot Umma Thurman also adds to his impressive biography.
I have seen Thurman speak a couple of times and he is an extremely entertaining and informative speaker. The slideshow below is a comic-form adaptation of one of Thurman's lectures on buddhist mythology. It's pretty wild stuff that, while mythological, could quite possibly exist in realms of possibility
