I just read this fascinating book titled Destructive Emotions - How Can We Overcome Them? A Scientific Dialogue with the Dalai Lama. It's "narrated" by Danial Goleman (Harvard prof and author of Emotional Intelligence) and it's a bit less condescending than his other books. He is narrating a conference with neuroscientists, philosophers, psychologists, the Dalai Lama, and some other Buddhist monk dudes from various school (both Western-born and Eastern-born).
Fascinating book, I highly recommend it as a great way to get familiar with some Eastern thought without feeling too ex-JW-weirded out. ;)
Anyway, there's this guy named Paul Ekman who studies physical expression of emotion - he can determine what are called microemotions, and he trains other to do so (this is the guy that trains the Secret Service to detect liars). Let me now quote from page 131 of the hardback edition.
"Paul later told me that he had been struck by how openly and freely the Dalai Lama expressed his feelings. His face, Paul saw, was unusually expressive, revealing moment - to - moment changes not only in his emotions but in his thoughts: You could sense in his face when he was concentrating, doubting, understanding, agreeing....
...But Paul was also struck by how quickly he (the DL) recovered from distressing emotion - and that his more typical mode of response to others was always seeing the potential enjoyment or amusement, the positive side of whatever was occurring.
...While most people acquire a self-conciousness that leads them to restrain the free expression of their emotions, the Dalai Lama appeared completely unself-concious about showing them...Most children by age four or five have come to feel shame about certain feelings, and so begin a lifelong pattern of restraint in that portion of the spectrum of emotion. But the Dalai Lama appeared to Paul never to have learned to be embarrassed about how he feels - something that occurs only in the most fortunate of children."
Not that the DL is typical...but I think this is in the vein of what you were referring to, Perry. At least, I hope someone finds it relevant.
