And "There is no ebb and flow of birth and death" -The Buddha, Lotus Sutra, Chapter 16
April 22, 1976, first Earth Day, age 14: I dream of scenes in 3,000-year-old Lotus Sutra, which I'd never heard of. 1988: The first time I read my dream in the Sutra. Birth/Death have "no ebb and flow." I made a promise in my dream. Here, I keep it.
