Day 1 covers the first half of Chapter 1, Introductory

Having last month considered what the crowd thought of the wonder displayed by the Buddha, Maitreya Bodhisattva repeats in gāthās.

Thereupon Maitreya Bodhisattva, wishing to repeat what he had said, asked him in gāthās:

Mañjuśrī!
Why is the Leading Teacher
Emitting a great ray of light
From the white curl between his eyebrows?

[The gods] rained mandārava-flowers
And mañjūṣaka-flowers.
A breeze carrying the fragrance of candana
Is delighting the multitude.

Because of this, the ground has become
Beautiful and pure;
And this world quaked
In the six ways.

The four kinds of devotees
Are joyful.
They are happier than ever
In body and mind.

The light from [the white curls]
Between the eyebrows of the Buddha illumines
Eighteen thousand worlds to the east.
Those worlds look golden-colored.

The Introduction to the Lotus Sūtra explains the Unique Qualities of the Lotus Sutra:

[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.
