[In Chapter 4, Understanding by Faith] Sakyamuni predicted the enlightenment of the four great disciples just as he had with Sariputra. Chapters Three (“A Parable”), Four (“Understanding by Faith”), and Five (“The Simile of Herbs”) had used parables to clarify the basic lesson from Chapter Two (“Expedients”) – namely, all teachings are only expedients leading to the One Buddha Vehicle. The parables were followed up with assurances of future Buddhahood. In the next chapter, “The Parable of the Magic City,” he employs a different teaching method, showing how events in the remote past can affect the present and the future. This is called teaching by affinities with the past. These three methods – doctrinal teaching, parables, and affinities – are known as the Three Stages of Preaching. All three are designed to make the basic lesson easy for us to understand.

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.

The Buddhist faith often expounds difficult doctrines consisting of abstract philosophical ideas. When it comes to the Lotus Sutra, however, such complicated dogmas do not appear on the surface. For this reason, some critics have argued that there are no doctrines in the Lotus Sutra. But this is not true. The Lotus Sutra does contain profound philosophical thoughts. Instead of using tortuous logic, however, the Sutra explains its philosophy in the simplified form of stories, drawing on examples familiar to us from everyday life. This is why we find many parables in the text.

This chapter is named “A Parable” because it contains a well-known story called, “The Burning House and the Three Carts” or “The Burning House of the Triple World.” The Lotus Sutra contains seven parables, commonly called the Seven Great Parables, and this is the first of them.

The first half of the Lotus Sutra (“Shakumon” or the “Theoretical Section”) is characterized by three stages of preaching. That is, the same subject is presented in three different ways according to the capacities of the hearers: first by a theory, then by a parable, and finally by means of a story from some previous existence. The teaching of the One Vehicle, for instance, is first presented theoretically in Chapter Two. Then it is illustrated by parables in Chapters Three, Four, Five, and Six. Finally its reason and purpose is clarified in Chapter Seven by a story from a previous existence.
