In the tradition of Buddhism, each person in the lineage of teachers develops a self-understanding which adds to the situation. The process is like handing down a recipe for bread. In each generation the bread is exactly like the original bread, but possibly more flavorful because of the added experience of the bakers involved in the handing down. In each generation the bread is fresh, delicious, and healthy.
