"Reverence is a state of mind not a set of rules. "
I never saw the movie series "The Adventures of Young Indiana Jones" until I came upon it on the History channel this week. Young Indy happens upon Albert Schweitzer in Africa. Schweitzer explained his philosophy for Reverence for Life to Indy while they travel up river.
It was one of those awe moments for me. The quote is one used in the movie.
P.S. After searching the library catalog and placing my hold, I learned that this is a 12 disc set produced by George Lucas. "Passion for life" is Disc 2.
