I think we have powerful role-models among us in the American West.

John Lilly suggests whales are a culture maintained by oral traditions. Stories. The experience of an individual whale is valuable to the survival of its community. I think of my family stories-Mother's in particular-how much I need them now, how much I will need them later. It has been said when an individual dies, whole worlds die with them.
