[I]n most sutras, the Introductory and Propagation parts are short and sweet, serving merely structural functions to complete the whole. In contrast, the Lotus Sutra contains a detailed introduction in addition to a general preface. This detailed introduction, unique to the Lotus Sutra, presents teachings that foreshadow what will be expounded in the following chapters. Secondly, the Lotus Sutra is structured as if the conclusion incorporates the main part. For example, after Chapter Ten, “The Teacher of the Dharma,” most chapters in the second division deal with the matter of keeping and propagating the Sutra in future worlds, which is, in fact, the major characteristic of a conclusion.
