The description of the Stupa springing from the earth has a very deep meaning. The earth symbolizes our bodies and minds as ordinary people. It also means this sahā-world, which consists of ordinary people. The enlightenment and salvation of the buddhas do not drop out of the clouds but spring from within ourselves. Enlightenment and salvation that spring from within ourselves are truly valuable and powerful, as the Buddha teaches us clearly here. His teaching is realistic and positive.
