Mental attitudes can be right or wrong; they can be noble or base. Faith that is formed through wrong mental attitudes is nothing more than superstition. Of course, there cannot be any errors in Sakyamuni’s teachings. But he expounded the law expediently in different ways according to our needs and abilities to understand. In this parable, the son, who believes himself to be base and humble, is a representation of all living beings. The father (the Buddha) educated his son with expedients in an effort to raise his base mind and make it into a noble one. This superior, noble mind is what we call the heart of the Buddha. Under the guidance of our father (the Buddha), we are all enabled to develop the heart of the Buddha, which every one of us already possesses by nature.
