Day 23 Text with annotations

Having last month repeated in gāthās the merits of the fiftieth person who rejoices at hearing even a gāthā of the Lotus Sūtra, we complete Chapter 18, The Merits of a Person Who Rejoices at Hearing This Sutra.

Anyone who persuades even a single person
To hear the Sūtra of the Lotus Flower
Of the Wonderful Dharma, saying:
“This sūtra is profound and wonderful.
It is difficult to meet it
Even during ten million kalpas,”
And causes him to go and hear it even for a moment,
Will be able to obtain the following merits:

In his future lives, he will have no disease of the mouth.
His teeth will not be few, yellow or black.
His lips will not be thick, shrunk or broken.
There will be nothing loathsome [on his lips].
His tongue will not be dry, black or short.
His nose will be high, long and straight.
His forehead will be broad and even.
His face will be handsome.
All people will wish to see him.
His breath will not be foul.
The fragrance of the utpala-flowers
Will always be emitted from his mouth.

Anyone who visits a monastery to hear
The Sūtra of the Lotus Flower of the Wonderful Dharma
And rejoices at hearing it even for a moment,
Will be able to obtain the following merits:

He will be reborn among gods and men.
He will be able to go up to the palace of heaven,
Riding in a wonderful elephant-cart or horse-cart,
Or in a palanquin of wonderful treasures.

Anyone who persuades others to sit and hear this sūtra
In the place where the Dharma is expounded,
Will be able to obtain the seat of Sakra or of Brahman
Or of a wheel-turning-holy-king by his merits.
Needless to say, boundless will be the merits
Of the person who hears this sūtra with all his heart,
And expounds its meanings,
And acts according to its teachings.

The Introduction to the Lotus Sūtra offers this on The Merits of that First Moment of Joy:

“Rejoicing” is the joy which one experiences when the significance of the Sutra first sinks in like a ray of light. When this ray of light first illuminates our soul, we have not yet undertaken any profound studies or done any difficult practices. But the merits of that first moment of joy are greater than those of any other practices we may undertake later. It is the hinge upon which everything else turns. This is the essential and most important point of this chapter. Faith is simple; it is also decisive.
